Holding a few pieces of straw paper in his hand, Li Chao felt like he was in tears. Pen "Fun" Pavilion www.biquge.info

"My heart, my breeze, my redbuds!" Finally, I don't need to use the toilet anymore, and I said goodbye to small wood chips, small bamboo boards, and waste bamboo slips, which is really moving.

The straw paper in his hand was not white enough, it was very yellow, even a little gray, and it was very rough.

It's thicker and harder, but at least it's straw paper, which is ten million times better than old bamboo slips and small wood chips. In the past, Li Chao's main hobby in his spare time was to cut bamboo slips, not to write books, but to make private toilet chips.

After being injured by a burr once, Li Chao got used to making his own toilet chips, and every time he cut a piece, he had to scrape it on his face a few times to confirm that it was smooth and smooth without burrs, and then it was completed. Usually, Li Chao sometimes doesn't have any money with him, but he must bring a small bag, which contains a handful of toilet chips that he has cut himself.

Although the toilets in many large households are extremely luxuriously decorated, incense is burned inside, and even ladies are arranged to serve them, and there are even dried dates to stuff the nose.

But this toilet chip is average.

What makes Li Chao especially unbearable is that many people's toilet chips can still be recycled. Some directly make a piece of cloth, some make knotted hemp rope, some bundle wood chips or bamboo slips, and get a bucket with water next to it, and after using it, throw it in, and there will be servants to clean it, and put it aside next time for later use.

How is this acceptable?

Li Chao can accept sharing vegetables on the same plate with others, and he will never tolerate sharing a toilet chip!

It's been two years, and finally there is straw paper.

For the sake of such a few pieces of straw paper, Li Chao even set up a workshop, and after studying for a long time, he finally had the current results.

Straw paper, which is made of straw pulp and processed with lime or shell ash.

Straw paper may seem very simple, but in fact it is very complicated, Li Chao's straw paper workshop, to process straw paper, after repeated optimization, still requires a full 72 processes.

To make 1,000 catties of paper, you need 150 catties of ash, 1,000 catties of straw, and about 200 catties of firewood.

The main material of straw paper is, of course, straw. However, there is not much rice cultivation in the Guanzhong area, so other hay is used instead, but the ash is more troublesome.

To make straw paper, you have to burn the ashes first.

Before the absence of cement, plaster was an important building material. Build houses and paint walls, the rich use ash and the common people use yellow mud.

The raw material of ash is actually shells, including oyster shells, clam shells, clam shells, nail shells and other shells. Generally, the place with the most shells is naturally along the coast. Fishing for shells in the sea, there are even special hull boats fishing for shells in the offshore waters, fishing up shells from the sea, and burning ashes.

Of course, in places like Guanzhong, which are not near the sea, then collect freshwater shells.

To burn the ashes, you have to build an earthen stove first. First dig a circular shallow pit on the ground, such as a basin, the area is about two meters wide, the pit is set up with bamboo like a net, and then seal a layer of top surface with straw mixed with mud, poke a small hole for ventilation, and then surround the edge of the stove. It is about a foot high, and a bellows must be built to blow the air at a door.

Calcination day and night until it is finished.

When the stove is burned, the shells must be mixed with chaff, sprinkled with some water, and laid with straw, it is best to sprinkle the shells with water after cooling, and wait for them to oxidize naturally into powder, and then become ashes.

This kind of ash is actually about the same as lime.

To make paper, you must first burn the ashes, and if you want to burn the ashes, you must first build an earthen stove and make a bellows.

In short, everything has to start from scratch.

Compared with leather paper, hemp paper, and bamboo paper, the manufacture of straw paper is not simple at all.

The best material for making straw paper is straw. A lot of rice is planted on the terraces on Li Chaoba, and these straws are used to make paper.

The straw had to be sorted first, and the straw used to make paper had to be old but not perishable, and it had to be dried at both ends.

Then you have to dig a pond, put water in the pond according to the amount, dissolve the ash and water according to the recipe, and then stir vigorously with a wooden rake. Put the prepared straw, about 300 catties at a time, into the big pond, trample on it with people or animals, let the dry straw absorb enough gray water, and wait for the straw to turn golden yellow.

Then they were brought ashore one by one, and the ash water was drenched and returned to the pond, back and forth many times.

According to the size of the pond, more straw can also be processed, generally 300 catties per pond, but you can also dig a large pond and make 3,000 catties per pond.

After the raw materials of the straw paper are pickled, they must be steamed and roasted.

The pickled straw is coiled around the earthen stove where the cauldron is buried, the straw is cooked, and it has to be kept warm for two or three days after the barbecue is finished.

The cooked straw is cut into small pieces of about one inch with a guillotine, and then a certain amount of water is added to the mill and pounded on the water mill until it is smashed.

Li Chao used a water mill here, which was driven by water power, saving a lot of manpower and animal power.

This process is also the most laborious process, and it has to be milled evenly until it is smashed into a thin rot and a paste.

Then use a bag to pack the paste, carry it to the pond, and stir it in the water to remove turbid impurities.

This process is time-consuming, and a bag of material has to be stirred in water for at least about 20 minutes, and in winter, it will be very hard.

At this time, the straw paper has just completed the processing of raw materials, and it is necessary to start the hands-on process.

Not all the straw paper produced by the straw paper workshop is used for toilet paper. In these years, those who are willing to wipe their butts with paper are estimated to be Li Chao.

Even if this is a newly developed straw paper, it is at most used by rich and noble people.

Therefore, straw paper is actually divided into several varieties.

The biggest use is actually wrapping paper.

The triangular wrapping paper used to package one, two, and two goods, also known as medium paper, has a side length of about half a foot. The tissue paper used to pack half a kilogram of goods is about seven inches long on the side.

There is also a sand tissue paper used to package a pound of goods, with a side length of about one foot.

There is also a large paper for packaging one pound of blue to two pounds of goods, which is used to package about two pounds of hard-shell goods.

Specialized in packaging large cargo as a single material.

Medium paper, thin paper, sand thin paper, large paper, side paper, single material, six different sizes of packaging straw paper.

This is the real purpose of straw paper, as for the use of toilet paper, it is just a small variety of piggybacking.

At this time, there are no plastic bags, and the store packs goods, many times using dried lotus leaves, some valuables, and also packaging with paper or cloth.

The cost of this straw paper wrapper produced by Li Chao is much cheaper than ordinary wrapping paper, and the cost is only one-third, or even lower.

Its practical lime can also replace the ash, the total production process is to build a lime marinade pool, and then prepare the material, turn the grass, dry, marinade, turn the material, wash the pulp, make paper several large processes. But in each major process, there are many small processes, one link after another, all of which are indispensable, and one of them is wrong.

The sequence, time, and standard of each process are all technical tasks and exclusive secrets. Li Chao split the whole set of processes after the experiment into 72 small processes, and divided the production of straw paper in the workshop into multiple workshops.

At the same time, fundamentally different product categories were created, and several different production groups were set up in each workshop.

Each workshop has a manager and a craftsman who are in charge of the technology and standards of the process.

If you use lime to make straw paper, then 100 catties of straw will use 20 catties of lime and 22 catties of water. With ash ash, it is 100 catties of straw and 15 catties of ash with 15 catties of ash

"Very good, very good!"

Li Chao visited all aspects of the straw paper workshop and was very satisfied.

This straw paper workshop can actually be regarded as borrowing chickens to lay eggs, using the opportunity of the printing workshop and the five horses to cooperate, introducing the Duan family's paper workshop, and then Li Chao got some papermaking craftsmen to learn inside, and then went to other paper mills to dig some craftsmen over, and had his own straw paper workshop.

However, Li Chao's workshop does not produce other jute paper, leather paper, bamboo paper, etc., but has specially developed a new type of paper, straw paper. Straw paper is not an invention of the Li family's workshop, and there are very few of them, but there are very few such as the Li family, which makes straw paper at such a level, and the cost is so low and the efficiency is so high.

"This straw paper, make it softer again, and send a hundred bundles to my house first." Li Chao said as he directly folded more than a dozen pieces of paper on his body.

Later, toilet chips can be thrown away.

Unconsciously, Li Chaodu has become a giant in the paper industry of Datang.

Counting this straw paper, Li Chao has created a new type of leather paper, bamboo paper, and straw paper.

"You have to choose a bright name to distinguish it from other old papers, and you have to establish a brand." Li Chao is now holding three new pieces of paper in his hands, and he is very ambitious.

Paper is the carrier of words, and it is very important for culture.

Cheaper paper, coupled with the advent of printing, has made book printing and newspaper printing more convenient, simple, and inexpensive.

The paper produced in the Bashang paper mill is mainly bamboo paper, that is, the bamboo processed from the tender bamboo that branches in the spring but has not yet made leaves, Li Chao used the technology of later generations to improve the existing production methods, and made the bamboo with lower cost, but better quality, to solve the problem that the original bamboo paper is very brittle, and the jute paper in Shu has been able to be on a par with the jute paper, the cost is much cheaper than the jute paper, and it is used for printing, and the effect is better.

"Let's call it raw edge paper!" Rough-edged paper is a famous variety of bamboo paper in later generations, it is said that because there is a collection of paper like to collect Fujian, Jiangxi and other real estate on the good bamboo paper, his collection of bamboo paper are stamped on the edge, the seal has his surname, Mao. Therefore, this kind of high-quality bamboo paper was later called raw edge paper.

The other is leather paper, which is made of mulberry bark, sandalwood bark, etc. This kind of leather paper, in the middle of the Tang Dynasty, there is a very famous variety, produced in Xuanzhou Jing County, Anhui Province.

However, there is no such paper yet.

"Well, let's call it rice paper."

Li Chao directly took it.

"After that, Ba Shang Paper Mill made every effort to produce raw edge paper for printing houses and newspapers. Straw paper mills specialize in the production of straw paper, which is used as commodity wrapping paper and toilet paper. Another rice paper mill was built to produce rice paper for calligraphy and painting. ”

Looking at several different papers, Li Chao smiled happily. In the future, the largest paper supplier in the world will not be the Duan family, but his Li family!

The Duan family has jute paper in his hand, but he has rice paper, straw paper, and raw edge paper, which is far more than the Duan family.

10,000 rewards plus one more, 192,000 monthly tickets plus two more, well, I still owe 12 chapters, and another chapter has risen, I don't know if I should be happy or heartbroken.

After this plot of Xuanwumen, there will definitely be a transition period in the plot, and it is impossible to keep climactic, so why not end. Don't worry, everyone, I'll write it well, you guys take a good look, how about it? (To be continued.) )
