"Uncle Zhao, please rest assured! I'm going to do my best. Wei Bao thought of Zhao Jinfeng's delicate appearance, and secretly made up his mind that he must work hard to make achievements on the road to the imperial examination, at least to get a child. Come to Daming, how can you improve your cultural attainments, right?

When Zhao Kehu heard this, he said happily: "That's good!" As long as you are willing to work hard, there is nothing you can't do, especially a smart person like Wei Gongzi. ”

Wei Bao smiled slightly, didn't say anything, and secretly thought that if Zhao Kehu knew that his goal was only Tongsheng, he would probably be angry and spurt blood.

Everyone says that he is smart, but he knows that his brain is just an ordinary person, if he is not a little more knowledgeable than the people of this era, he is smart.

But what things are heard too much, it's easy to take people seriously, everyone says he's smart, and now, Wei Bao sometimes thinks himself, it seems, he's quite smart?

Although there was no wine, the meal was sumptuous, and everyone ate and drank with great joy.

In the afternoon, more than 200 shareholders discussed how to do a good business, how to select management, who to be partners, and how to operate.

Xu Rui didn't want to go, because she had done it in Qinglou before, and she didn't like to participate in crowded occasions.

But she was hosted by Wei Bao's secretariat, so she had to go.

Although Xu Rui refused to say it explicitly, Wei Bao could guess Xu Rui's concerns, and then Wei Bao thought of a way to simply let Xu Rui change into men's clothes, thicken her eyebrows, and not apply fat powder, and come to the men's style of Wang Qixian's beauty. In addition, she was still in the process of development, and the female college changed eighteen. In this way, even if you meet a former acquaintance, you can't recognize her, at most you will feel a little familiar.

Moreover, in fact, Xu Rui has been out of the Qinglou for a month, even if she meets someone she knew before, if she doesn't speak, it is not easy to recognize her, like Wu Sanfeng has been to Yihong Courtyard before, and he has seen Xu Rui, but he didn't recognize her. No one would have thought that the original top brand of Yihong Courtyard was not only from Liang, but also became a personal maid by Wei Bao's side.

As soon as Xu Rui wore men's clothes and a scholar's hat, her appearance suddenly changed greatly.

provoked Wang Qiuya and Fan Xiaolin to praise again and again, and they all said that they were good-looking.

"Childe, I will wear men's clothes in the future!" Fan Xiaolin said coquettishly to Wei Bao.

Wei Bao felt funny, looking at Xu Rui dressed in men's clothes, but it was difficult to hide the two bulging breasts, and suddenly felt that it was an alternative stimulation, and suddenly became angry, and without thinking about it, he promised Fan Xiaolin and said: "Okay, you can wear whatever you want, men wear women's clothes are disgusting, women wear men's clothes, I think it's very good, it's good-looking." ”

Fan Xiaolin couldn't help but be overjoyed when she saw Wei Bao agree, and nodded happily.

"Qiu Ya, why don't you change into men's clothes in the future? It's also much more convenient to go out with your son like this. Fan Xiaolin proposed to Wang Qiuya: "In the future, the women under me, as well as the people in the secretariat under you and Xu Rui, everyone will change into men's clothes!" Who says women can't do things? Let's prove that we can not only do things, but also do better than men! ”

After Wei Bao heard this, he couldn't help but nod his head, feeling that Fan Xiaolin's words were very progressive, which was a manifestation of ideological enlightenment, and should be encouraged.

Wang Qiuya was originally blushing and pink-faced, but she was reluctant, but seeing Wei Bao's encouragement, she thought that Wei Bao liked to see women wear men's clothes, and out of her admiration for Wei Bao, Wang Qiuya shyly agreed to wear men's clothes in the future. But I secretly thought that I used to have no money and couldn't afford to wear good clothes, but now I have silver, but I can only wear men's clothes, which is a pity. And I'm afraid of the jokes of my father and mother, and I always feel that women are embarrassed to wear men's clothes.

In fact, in the eyes of Wei Bao, a modern person, there is not much difference between women's clothing and men's clothing in this era! A man's coat is also a robe, and the difference is only in the top itself.

Women who have not been married are tightly wrapped, and women who have become relatives have a larger scale and will show their breasts slightly. The overall costume is similar to the 98 version of [Water Margin], although the interpretation is of the Song Dynasty, but the costumes of the Ming Dynasty have not been greatly changed. It's just a little more delicate, and the overall style is in the same vein.

In the afternoon, Xu Rui went to the board meeting, Fan Xiaolin went to work with her logistics, and Wei Bao took Wang Qiuya to the chemical factory.

His own plan is to go to Shanhaiguan the day after tomorrow to prepare for scientific research, and at that time, it will be time to launch new products in Shanhaiguan's Tiandi firms! On this day of the first shot, he, the chairman, will definitely be present.

In two days, the quality of soap and kerosene lamps had to be improved, and mass production was required, and matches had to be produced in large quantities, which was a lot of pressure.

Although these are relatively easy things to come up with, they belong to the extracurricular homework of modern middle school students' chemistry classes, and the difficulty of the manual work level of interest groups. But for the three knives of Wei Bao, it is still Alexander.

Match is based on the principle of object friction heat generation, using the chemical activity of strong oxidant and reducing agent, to make a kind of fire tool that can friction fire.

In the second half of the eighteenth century, yellow phosphorus was mainly used as an ignition agent. Because yellow phosphorus was toxic, it was gradually replaced by phosphorus sulfide matches. Although the latter is non-toxic, it may spontaneously combust at any time and is very unsafe.

In 1855, the match factory established in Sweden in the world successfully developed safety matches, which were gradually adopted by countries all over the world.

It's 1624, and if Wei Bao could make matches now, it would be more than 200 years earlier than the original history! Even if it can stimulate the progress of Europeans to a certain extent, it is already scary to double the gap of more than 200 years, and it is absolutely impossible to achieve the level of scientific and technological cognition of Wei Bao within a hundred years.

The sides of the matchbox are coated with red phosphorus (ignition agent), antimony trisulfide (Sb2S3, flammable) and glass powder; The substances on the match head are generally KClO3, MnO2 (oxidant) and S (flammable).

When the two sides are rubbed, the heat generated by the friction causes the red phosphorus in contact with KClO3 and the other to ignite and cause the flammable material on the match head to burn, causing the match stick to catch fire. The advantage of safety matches is that red phosphorus is not toxic, and it and the oxidizer adhere to the side of the matchbox and the matchstick, respectively, so that the two do not come into contact when not in use. That's why it's called a safety match.

At the beginning of the twentieth century, modern matches were introduced to China and were called foreign fire, fanhuo, etc.

Before Wei Bao and Wang Qiuya arrived at the chemical factory, Wei Bao first found a way to record how to make matches from his mobile phone through the index.

The three 'Crossing Giant Enthusiast' brothers all have records about matches, and it seems that these brothers have a consensus and have all thought of using matches as a fist product to make a fortune in ancient times.

After copying it, Wei Bao read it all and suddenly realized a new problem, he seemed to have neglected the packaging, and the packaging had to use a lot of paper!

And the production of matchboxes directly requires the use of paper!

"Gotta get a paper mill!" Wei Bao said to himself: "I don't know if there are any people in the Military Industry Department who know how to make paper, if not, I have to ask more than 3,000 people whether there are masters who know how to make paper." If there are more than 3,000 people, then you have to go outside and look for it! ”

Wei Bao suddenly felt that time was really too tight! It seems that he forced himself to be like this, if he didn't do the preparation work first, and didn't have a perfect formed product, he started to prepare to sell goods.

Wait for the shops, events, sales joint-stock companies, all aspects are ready, can't get a decent product, don't you shoot yourself in the foot?

Wei Bao copied the cheat sheet, and then hurriedly took Wang Qiuya, under the attendants of his entourage, to the chemical factory.

As I walked along the road, I went through it in my head, thinking about how to start manufacturing and what the steps were.

For the production of matches, Wei Bao is not particularly nervous, because now he has the main chemical raw materials.

The most basic three acids and two alkalis, namely nitric acid, sulfuric acid, hydrochloric acid and sodium hydroxide NaOH, sodium carbonate Na2CO3.

Wei Bao now has these raw materials at hand.

Sodium carbonate is not alkali, it is salt, commonly known as soda ash and soda, which is alkaline.

After a whole set of generating units is put into Warship Bay, the industrial production of these chemical basic raw materials is no longer a problem. As long as the scale is not a few tons per day, but a dozen tons, it will do.

Although the time was tight, Wei Bao went to see the manufacturing progress of the steam engine first.

"It's almost finished, and it will definitely be installed and put into production before midnight tonight." Song Yingxing reported to Wei Gongzi.

Wei Bao nodded, and took a closer look at the remanufactured steam engine, which was one size smaller than the original, and the biggest change was in the boiler.

The boiler has an exhaust device added.

Although this will increase energy consumption, it can greatly improve the safety factor, and the pressure gauge will open the valve in time to release the gas if there is a slight danger warning.

"When you use it, let the boiler worker check it more, before the boiler wall is about to crack, there will be a strange sound, once you feel that something is wrong, you will quickly stop the machine and renovate it." The blacksmith in charge also said.

Wei Bao snorted, "Well done!" "Although I blew up a boiler, I feel that the tuition fee of a few hundred taels of silver is not wronged, at least now everyone has greatly improved their safety awareness, and it is easy to do it with such a safety concept and the concept of maintenance. After all, I have never been in contact with industrial production before, and I have not been in contact with mechanical engineering.

When Wei Bao arrived at the chemical plant, the R&D and improvement of soap and the R&D and improvement of kerosene lamp glass covers were still in progress, and a group of people from the Military Industry Administration were working intensively.

"President."

"President."

As soon as everyone saw Wei Gongzi enter the shed, they immediately stopped what they were doing and stood straight one by one.

According to Wei Bao's requirements, the Military Industry Administration also belongs to the military system, and they have undergone simple military training in the past few days. It's not that they want to fight, but they just have a military posture and military appearance, and they have the appearance of soldiers.

Wei Bao waved his hand: "Let's do things!" As he spoke, he walked over and picked up a piece of soap and looked at it, which was much smoother than the soap he had seen in the previous two days.

"The appearance has improved a lot, and I don't grind my hands anymore." Wei Bao stroked the bar of soap.

"Yes, we deliberately did the grinding, the material was grinded more finely, and the impurities were also cleaned." Deng Erxian replied: "It's just that if you do this, it's too laborious, and I'm afraid that the output won't go up." ”

Wei Bao nodded, secretly thinking that it was all manual work, and the output was a problem: "Let's get the quality up first!" The output is gradually increasing, and when the time comes, it is necessary to use the assembly line, stirring with a steam engine, and using a steam engine to drive. "Now there are no belts, but using wood for gears and wood for transmission boards should be able to make an assembly line.

Everyone didn't know what the assembly line meant, Deng Erxian asked this question on behalf of everyone, everyone could see that President Wei liked Deng Erxian and liked to talk to her, so she talked to the president, and Deng Erxian had a lively personality and an active brain, everyone liked her, and she was the only woman here, and she was tall and big, almost like a man, in short, Deng Erxian is a girl who is very suitable for doing scientific research with a group of big men.

Wei Bao casually drew the mixer and assembly line on the drawing, the assembly line is similar to the pumping truck with feet, everyone already has the concept of mechanical manufacturing, and they are all blacksmiths, they can understand at a glance, they can't help nodding, and they all secretly praise President Wei is really smart, and he can think of anything.

"How to pack? Have you all thought about it? Wei Bao asked.

"I've thought about it, don't you use thatch, aren't all soaphorns packed with thatch? Save money and trouble. Deng Erxian replied.

Wei Bao was almost defeated, with thatch? How ugly is that? "Packed in a carton! It doesn't add much cost, but it is much more beautiful! And it can also help the business advertise! ”

Wei Bao has paid attention to the goods on the market, and the businessmen of this era already have a strong concept of advertising, but most of them advertise the store! I will not advertise the product itself, such as the product packaging, even if it is packaged in paper, at most the colors of red, red, green and green are brighter, and I will never think of printing the store and product name.

"It's good to use a carton, it must look much better, and it should be easy to preserve!" President, my brother and I can make paper! Deng Erxian raised his hand and said.

Wei Bao couldn't help but laugh, "You and your brother are really all-rounders?" Looking for the two of you to enter the Military Industry Department, it is considered to be the right person. ”

"Most people here do." Deng Erxian said with a smile: "As long as you are a child of a craftsman, most of them are generalists, and you have to know everything, because the local government often sends some messy chores." ”

Wei Bao nodded, thinking that the current circulation of commodities and the circulation of the population is also a bit beneficial, and indeed every small area has been built into a small world that can be self-sufficient, and a small society has also created the fact that most of the craftsmen are generalists.

Wei Bao immediately asked everyone about some knowledge about papermaking.

Papermaking was an important invention of the working people of ancient China. There are two forms: mechanical and manual. The mechanism is to continuously carry out on the paper machine, dilute the pulp suitable for the paper quality to a certain concentration with water, preliminarily dewater the net part of the paper machine, form wet paper sheets, and then press and dehydrate, and then dry into paper.

By hand, a frame with bamboo curtains, polyester mesh or copper mesh is used to copy the fibers scattered in the water into wet paper sheets, which are pressed and dehydrated, and then dried or dried into paper.

The biggest difference between the mechanism and the handmade paper is that because the handmade paper is manually pulped, the fibers in the pulp are well preserved; The machine-made paper is pulped by machine, and the pulp fibers are crushed.

This makes handmade paper much better than machine-made paper in toughness and tensile force. There is an uneven distribution of fibers in the longitudinal and horizontal direction due to the difference in pulp net speed in machine-made paper, and there is no uneven distribution ratio of fibers in handmade paper, especially in calligraphy and painting paper, such as rice paper.

After the invention of papermaking in 105 AD, papermaking spread from Henan to other economically and culturally developed regions. Cai Lun was enshrined in Yangxian County, Shaanxi Province as the Marquis of Longting, and papermaking technology spread to Hanzhong and gradually spread to Sichuan.

Since the beginning of the Jin Dynasty, China's famous calligraphers and painters have emerged, which has greatly promoted the development of calligraphy and painting paper. For example, Wang Xizhi, a calligrapher in the Eastern Jin Dynasty, greatly improved the use of calligraphy and painting paper during his father and son period.

The writing paper of the Jin Dynasty and the Northern and Southern Dynasties was made of hemp and bark, and the surface of the paper was coated with starch and white mineral paint and polished.

After the Sui Dynasty unified the north and south, the Tang and Song dynasties inherited and developed the achievements of papermaking for hundreds of years, and opened up the heyday of handmade papermaking in China in the Tang and Song dynasties: the prevalence of calligraphy and painting and Buddhism in the Tang Dynasty made the demand for paper increase dramatically, and the raw materials for papermaking expanded to use rattan and mulberry bark.

The calligraphy and painting paper is also boiled into paint with starch nitrate, then waxed, and finally polished and calendered with coarse cloth or stones. The writing paper is also dyed yellow with barberry to ward off beetles.

During the Northern Song Dynasty, Anhui Province has adopted the method of harvesting at night by day, bleaching hemp fiber to make paper, and the raw paper copied out is smooth and white, and has good durability.

In the Southern Song Dynasty, bamboo paper was abundant in the south of our country, Wang Anshi, Su Dongpo, etc. all liked to write on bamboo paper, thinking that the bamboo paper ink was bright and bright, and the pen was bright, which was imitated by many literati and ink writers at that time, thus promoting the development of bamboo paper. The Song Dynasty was not only rich in bamboo paper, but also began to use rice and wheat straw to make paper. In the Northern Song Dynasty, Su Yijian's "Four Scores of Study" recorded that Zhejiang people used wheat and rice stalks to make pulp and oil rattan to make paper.

By the Ming Dynasty, the technology of making paper from bamboo had been perfected, and Song Yingxing's "Tiangong Kaiwu" systematically described the production process of making paper from bamboo, with illustrations of the production equipment and operation process. It is the earliest work that systematically describes the papermaking process in China.

The paper industry is a processing industry that mainly provides commodity materials such as packaging, printing and information industries, and is also a general competitive processing industry with a high degree of marketization and nationalization.

The development of the paper industry is closely related to the national economic and social development, and the economic development provides strong support for the development of the paper industry.

The equipment investment in the paper industry accounts for about 60% of the total investment, and the degree of automation is higher than that of the general paper industry; Every time you increase the production capacity of 10,000 tons of pulp, you need to invest a lot! Wei Bao estimated according to the prices of this era, if it really wants to be able to mechanize production, at least three or four hundred thousand taels of silver will be smashed in!

Due to the large investment in paper industry equipment and high fixed costs, expanding the scale has become an effective means for enterprises to reduce costs and enhance competitiveness.

The paper industry uses raw materials such as wood, bamboo, reeds and other raw plant fibers and waste paper and other recycled fibers, which is a resource-constrained industry and highly dependent on fiber sources.

Wei Bao took out the cheat sheet and compared the difference between the 'ancient' papermaking process and the modern papermaking process on the cheat sheet.

Wei Bao found that one of the elements of papermaking is fiber pulping and percussion, using a stirring knife and high-horsepower machinery to make the plant fibers bifurcate and break, and then copied into paper with greater binding force, unlike smooth filamentous fibers that are easy to slip off; In addition, the debris and paste produced after pulping have the function of filling pores and bonding paper when making paper. Ancient or modern hand-made paper, the use of frame bamboo in the pulp to sieve the floating fibers in the pulp, because the sieving action has the front and back short sides and the left and right long sides of the sieve, so the hand-made paper fibers can be very uniform in various directions and freely arranged, without the silk flow problem mentioned in this article.

In addition, the modern waterless dry papermaking method uses air to disperse and glue the paper, and its fibers are also arranged in a free form and there is no filament flow direction.

The silk flow of paper has a great impact on the "properties" and "shapes" of paper, such as tear resistance, curl, elongation, shrinkage and processing origami, book stiffness and opening adaptability, etc., all have an absolute impact.

The modern papermaking process can be divided into the main steps of pulping, modulation, copying, processing, etc.: pulping is the first step of papermaking, and there are generally three methods of converting wood into pulp, such as mechanical pulping, chemical pulping and semi-chemical pulping.

The modulation of paper stock is another key point of papermaking, and the strength, tone, printability, and length of paper shelf life after the paper is completed are directly related to it.

The common modulation process can be roughly divided into the following three steps: 1. Loose slurry; 2. Beating; 3. Glue and filling.

The main work of the process papermaking department is to make the thin paper stock evenly interwoven and dehydrated, and then dry, calender, roll the paper, cut, sort and package.

Wei Bao took the cheat sheet and explained the contents of the cheat sheet while discussing with everyone, which gave everyone a lot of inspiration.

"How long does it take to get the paper out?" This is Wei Bao's main concern, for fear of delaying the sale of soap and kerosene lamps.

"Within three days, it will definitely be possible, and Childe can be thick or thin if he wants." Deng Erxian said with confidence: "If I was in the village, I wouldn't dare to say it so quickly, but in the chemical plant, I would definitely be able to do it." More than 30 skilled masters work together, cooperate together, and do everything quickly. ”

Wei Bao nodded and said: "The paper will be produced within two days, and the paper for packaging will be the main one." Wei Bao said, taking out a sample of the packaging box, and another sample of the match, "I want this kind of paper!" ”

A group of people circulated the samples given by the president, touched them, pinched them, and flicked them with their fingers, all of which said that there was no problem.

Wei Bao was relieved, feeling that he still had to solve the problem on the spot, and discussed with his technical workers to do it, and the effect was much better. I thought it was a simple thing, but I didn't expect it to be difficult in the production process.

Wei Bao originally thought it was very simple, but he didn't expect that after the steam engine from the modern water station was transferred, although the bubbles were significantly reduced and uniform, much better than the original, but the oval interface was still crooked and twisted, and it could not meet the requirements of mass production.

"Why still not?" Wei Bao asked.

Everyone didn't speak, and even Deng Erxian looked embarrassed: "I don't know, everyone has been experimenting, there will still be bubbles, and no matter how you do it, there is no way to make it as regular as the sample given by the president." ”

Wei Bao sighed, "I can only change it to a square one first!" Make a glass cover out of four small pieces of glass. The base and the top cap have also been changed to square shapes! This will solve the glass problem for the time being. However, if you do this, it is not only aesthetically pleasing, but also increases the cost! In the future, it will take tens of thousands of tens of thousands of productions, and the cost of adding one cent of silver will be increased, and a hundred will be one or two pieces of silver! A thousand is ten taels of silver! 10,000 is 100 taels of silver! A million is 10,000 taels of silver thrown into the water! So, this problem should be solved as soon as possible. ”

Wei Bao said. He's very cost-conscious. The lower the cost, the greater the profit, and in order to compete with the candles, lanterns, and oil lamps that are now popular on the market! If you can't sell expensive, cost is even more critical.

A group of people from the Military Industry Department agreed in unison.

Now that the problems of soap and kerosene lamps have been solved temporarily, Wei Bao breathed a sigh of relief, and only matches remained.

Thinking that matches would use a large amount of incendiary materials, which is forbidden, he originally wanted to make them in a chemical factory, so he temporarily changed his mind: "Dong Huojin, Fu Jiguang, Qian Xuexue, Zheng Ergou, Deng Daliang, Deng Erxian, a few of you will arrange what I just said, and then come with me." ”

Wei Bao called out a few backbones and wanted to take them to Gunship Bay to research and development, planning to put the match factory in Warship Bay! He said to Wang Qiuya again: "You go back first, I still have some things." ”

Wang Qiuya was a little unhappy when she saw Wei Bao driving her away, and felt that Wei Bao seemed to have something behind her, and didn't seem to treat her as 'her own person': 'Where are you going?' I can't go? ’

Seeing Wang Qiuya's appearance, Wei Bao was a little unhappy and a little soft-hearted, and said softly: "It's not that I can't let you go, that place is not suitable for you to go for the time being, be obedient." I'll be back later today. ”

Wang Qiuya saw Wei Bao approaching her, and whispered to herself softly, she immediately became happy, and nodded obediently: "Hmm." ”

Wei Bao smiled, secretly thinking that it is better to often restrain his temper, many times, using a soft way, than a tough way, the effect is much better. He is already a 'leader', not a modern petty manager, and he always maintains his demeanor, whether it is in front of his own women or his subordinates, it is better than speaking sharply.

Dong Huojin, Fu Jiguang, Qian Xuexue, Zheng Ergou, Deng Daliang, and Deng Erxian hurriedly changed the production process of kerosene lamps according to what President Wei just said.

Then there is the determination of the papermaking process. According to the mechanical stirring proposed by Wei Gongzi just now, the production process was established.

Wei Bao has been listening to the scene, rarely expressing opinions, in fact, others have experience, he has no experience, can only talk about the three 'crossing giant enthusiasm' brothers copied the information on the Internet in the early stage, and other further insights, he can't put forward them, so if he wants to open his mouth to guide, it is better not to speak.

An hour later, the group headed for Gunship Bay.

After Wei Bao entered Warship Bay, he said what he was going to do: "I showed you the matchbox just now, and the matchfactory is located in Warship Bay. Wei Bao said, took out a box of matches, and struck a match with a bang, "This is a match!" ”

In the same way that Wei Bao demonstrated matches to a group of Lizheng, A Chang and wealthy people in the lobby of the State Guest House before, a group of people from the Military Industry Department also widened their eyes one by one in surprise, and they all let out a sigh.

Dong Huojin even seemed to think of something, "President, a little spark can make the whole little stick burn in an instant!" It's the same principle as a smokeless fire. ”

Wei Bao nodded, "It's the same." Although I don't know what Dong Huojin thought, I feel that this sentence after another can be regarded as an affirmation of his thoughts. Wei Bao knew that Dong Huojin had not developed the smokeless fire gourd these days without him giving specific production materials, he must be in a hurry, and he must have encountered a bottleneck, but Wei Bao never urged him from beginning to end.

"President, can I give it a try?" Deng Erxian asked.

Wei Bao nodded and handed the match to Deng Erxian.

Deng Erxian learned from the president, took out a match from the matchbox, wiped it lightly on the match skin, snorted, she also struck the match, and said in surprise: "It's so convenient, I don't know how much more convenient than the fire fold?" ”

The fire flap, flint, and fire fold are a set, and the fire fold is a simple lighting and fire appliance that is easy to carry.

The best method of making paper is to soak the white (red) potato vines in water, take them out and beat them flat, then soak them and add cotton, reed tassels and then hammer them, dry them, add nitrate, sulfur, rosin, camphor and other flammable substances and a variety of spices. Finally, fold into a long flat tube or twist it into a rope, burn it at night as if there is no fire and put it in the bamboo tube, take it out and burn it when you use it, it is very flammable, but the cost is very high, and it is only suitable for rich people. Ordinary people still can't afford it.

However, the paper of the ordinary fire origami is just ordinary unpunched paper money (money paper burned to the dead), and it can also be straw paper. When making, the paper is cut into a length longer than the bamboo tube, and then rolled up with moderate tightness, rolled into a thick size in the bamboo tube, and finally inserted into the bamboo tube. Then light it and cover it with a ventilated lid. When it's time to use it, pull off the lid and blow gently on the fire fold, and blow skillfully.

In the countryside, it is mostly used for smoking shisha and making fires.

"Matches can not only light kerosene lamps, but also replace fire breakers altogether." Wei Bao said: "The fire fold is troublesome to make, and it will be extinguished after a long time, besides, the paper is so expensive, it is used to start a fire, and the average person can't bear it at all, most people still use the flint to hit the fire, and they can't light it after knocking thirty or forty times!" I've had enough of this before. ”

When everyone heard this, they laughed together, everyone has the experience of flint hitting to make fire, and the convenience is not comparable to the president's match!

"Flammable wood is made into small sticks, that is, match stems, and one end of which is dipped in wax oil and potassium chlorate, called match heads, to make matches. The packaging box is coated with a phosphorus surface containing red phosphorus and white phosphorus. When using, the match can be ignited by rubbing it on the phosphorus surface, which is extremely convenient. The general process of manufacturing process mainly includes: sawing wood, peeling bark, rotating blades, cutting stems, and drying; screening, stemming, stemming, oiling, slurry preparation, dipping, drying, unstemming, spinning box pieces, cutting box pieces, pasting boxes, drying; Set of boxes. The carton is: printing, indentation, slitting, pasting, boxing, boxing, phosphosphosphine preparation, phosphorus brushing, encapsulation, and packing. Wei Bao said to the match.

It would be nice if it could be produced mechanically, but Wei Bao had no way at all: "You do it manually first, I have the material formula here!" See if you can figure it out yourself, think of more ideas in the future, and every step requires mechanical production to save manpower. ”

"Yes, President." Everyone agreed in unison.

Fu Jiguang recorded every step of President Wei's words in detail, and then took the cheat sheet given by the president and copied it again, and read it to everyone in the process.

Although it has only been a few days since the literacy eradication, a group of people from the Military Industry Administration and the Industrial Bureau already know a lot of words, and adults are not slow to learn things, but they have a bad memory, and they are easy to forget after learning, and their speed is definitely not worse than that of children.

Wei Bao also dispensed medicine with everyone on the side, and replaced tetraphosphorus trisulfide with sulfur in the safety match head. The general frictional heat is not enough to make the medicine head react, only when the phosphorus layer on the side of the matchbox is scratched, the frictional heat first causes the sulfur to react with potassium chlorate, releasing more heat energy, and promoting the chemical substances in the medicine head to react and ignite.

The chemical reaction is too violent, and the fire is too violent, which is not conducive to use. In order to control the speed of fire, some fillers such as quartz powder need to be added to the medicine head to make the medicine hair fire slow and stable; In addition, potassium dichromate and pigments are added to improve moisture resistance and appearance.

The raw material of the match is a contraband, but when it is made into a finished product, people do not know what the specific raw material is used, and no one can say anything.
