In the early morning of this day, the sun was still shining. The sun does not distinguish between you and me, regardless of nationality, it shines on everyone.

At the lumber mill, Director Song Shida sneezed loudly.

He rubbed his nose and said jokingly, "Who's thinking about me?" ”

At this time, the lumber mill area was filled with a variety of flavors.

There is a smell of camphor, which is the camphor workshop boiling, no, it is extracting camphor.

There is also the scent of rosin, which is the rosin workshop where the rosin is extracted.

There is also a smell, which is the wood tar workshop processing wood tar.

The reason why the word processing is used is because the use of wood tar by the traversers has gone to a higher level, and they no longer directly pack and express it to the Chiji Agricultural Base, and they can now refine it.

How much wood tar can be produced from 1 ton of charcoal?

Under the careful processing of the traversers, it can produce about 2o-3o catties of wood tar.

The main component of wood tar is wood creosote oil, which can be prepared by distilling the tar made from wood, treating it with sodium hydroxide, re-acidifying and re-distilling to separate it from other components. Wood creosote is a colorless liquid that is mainly used as a disinfectant and preservative.

To be honest, if measured by the condition of cost performance, it is not very useful, and it takes a lot of time to refine it.

Therefore, for the treatment of wood tar, the traversers temporarily chose the simplest method, the precipitation method. After precipitation, the wood tar is divided into two parts, the upper layer is coarse wood vinegar, and the lower layer is the purer wood tar.

Then use the static sinking method, put the coarse wood vinegar in the container and let it stand for more than 1o days, 3 layers will be separated, and the impurities such as the upper 1o% light oil and the lower 3o% tar will be removed, and the middle part is the wood vinegar with higher purity. Then add charcoal powder to this wood vinegar in proportion to adsorb the impurities in it, and after mixing, stirring and filtration, you can get some refined wood vinegar.

Originally, I wanted to refine methanol from it, or methanol is also called wood alcohol!

However, the traversers have made a series of arguments in advance that its production is too low, and it is quite dangerous.

Pull it down, in the future, it is better to be honest and practical to make gas, not to mention the waste of tonnage with one more set of equipment, methanol is not what is urgently needed first, and it will be said later.

Wood vinegar is a good thing, and it is said that it is the first chemical product of the traversers. I have to say a few more words here.

There are so many uses for wood vinegar that it should be the first choice for travelers.

The reason is simple, in the process of making charcoal, tar appears, and it is liquefied to obtain wood vinegar.

Therefore, wood vinegar is made by concentrating the mineral energy in the wood when the tree is carbonized. It contains natural minerals such as K, Net, Fe, etc.

In fact, in the tar delivered from the estuary base to the Chiji agricultural base, what they mainly need is this thing. Spraying wood vinegar in the soil can prevent seed blight, can also be used as a disinfectant for the soil, and can kill pests such as root nodule nematodes. These are all certified in advance, as written above.

At the same time, it can promote the growth of various vegetables, fruit trees, rice, tobacco and other plants. In addition, wood vinegar can also act as a variety of fertilizer companions, inhibit the growth of weeds, reduce the amount of pesticides and act as a repellent for insect pests.

Once upon a time, when the girl Wu Yongmei kindly persuaded the Ming farmers to use it, they Ming farmers would stroke their beards and nod their heads, but why should they go.

The Ming peasants thought that since ancient times, they had never heard of farming to listen to a woman, let alone a ...... Such a woman. We are afraid of you, but that doesn't mean we have to listen to you.

But when the contrast between using it and not using it comes out, it's the difference between the size of a dog and a donkey!

This time, no one took the initiative to teach them, and the Aketo peasants immediately learned. The key question is to guide the peasants!

But the Ming peasants now ask for a horse ticket for the wood tar that they didn't want for nothing, a pound and a horse ticket.

In the eyes of Director Li Ziqiang, Director Jianguoan is also a petty person, which can be used as an argument.

Wood vinegar also deodorizes. It can be used to deodorize the foul odor of fresh items such as toilet feces disposal, livestock houses and fish markets. Spray wood vinegar on a foul-smelling place to eliminate the odor and keep the air fresh, spraying it can last for about 5 days, of course, the weather is not too hot.

This made the two ancient people who lived in the same estuary base always feel that the people of the Han and Tang groups are weirdos, and even their toilets don't stink.

Wood vinegar can also be used in the food industry ham and sausage, after the wood vinegar maceration and then smoked, not easy to insects, the taste is more delicious, in the estuary base it is mainly used to deal with pickled salted fish.

But Director Li Ziqiang said: "Ambassador, you must have dried it for my food factory, you know that I must eat salted fish porridge in the morning." I'm afraid of your purification technology - you know, once there is methanol in it - you know, your brother is still short-sighted now. ”

Director Song Shida said: "Li Zi, you don't trust people too much, right? I also eat it myself, which has been treated with wood vinegar. ”

"Really, then I'm relieved."

Even it can play a role in antibacterial and sterilization, and can be used for the treatment of dermatitis, athlete's foot, and itching diseases. After testing on Dutch and Ming patients, Dean Ma Jun officially said that it does have a very good effect on anti-itching and anti-inflammatory. The most scary thing is that it can also be used as a feed additive, which can improve the meat quality of livestock and farmed fish, improve the quality of fish eggs and improve nutrition.

Of course, the latter food medical grade wood vinegar has higher purity requirements, and the traversers generously equipped the wood tar treatment workshop at the estuary base with a low-pressure boiler and distillation equipment for the low-pressure distillation and purification of wood vinegar at the estuary base, which is relatively simple.

The Chemical Engineering Department left a technician here, he said: "What are you afraid of, the methanol content in it is less than three percent, and the boiling point of methanol is still low, only 64.7 degrees, and it is easy to wave, so it is difficult to keep it." ”

Wood vinegar is so useful, so why haven't we heard of it being used in large quantities in the world? The cost, my friend. Do you want wood tar like the travelers?

But the traversers are still worried.

How to stay in the charcoal energy stage! The traversers are in a hurry, when will they be able to rise to the coal energy stage?! But I can't help it, just wait.

The precipitated tar can belong to the industrial product, although the tar has been partially dissolved, it can still be made into purer wood tar with higher purity.

In this way, its grade has come up, and now it has become a high-temperature resistant material, with high temperature resistance up to 28o degrees, and waterproof, which is an excellent material for shipbuilding industry, paint industry, anti-corrosion and high temperature resistance. At the same time, it has the effect of growing plants in agriculture and has excellent insecticidal effect.

Having said all this, all the equipment is installed in one workshop. There are plenty of people, because there are only four people, and they still work in turns.

Wood asphalt is a kind of tar asphalt, which is obtained by processing wood tar again. What's the reprocessing, let's build a calcining furnace to burn, fortunately, it's not too difficult. But it can only be used as a transitional product.

Wood asphalt has a high content of light components, high temperature sensitivity, volatile aging, short service life, poor durability, and rarely uses wood asphalt in the engineering of that world, have you ever heard of it?

But the shipyard liked it, the plug seam was good. Director Li Ziqiang also likes it, it can be glued to the mold.

Therefore, it is certain that Director Song Shida can smell all kinds of pungent smells in this lumber mill, not that anyone thinks of him, who wants to miss him?

This lumber mill is just a general term, and it refers to this piece of land.

This also includes industries such as wood processing plants, charcoal, bricks, bamboo and rope making. It's a lively story, but there are less than a hundred travelers here, and less than a hundred indigenous temporary laborers.

Our estuary base is short of people!

Today, Director Song Shida wants two ancients to come here, and there is really a new task for them.

With the cement of the Red Star Cement Plant on the field, there is a shortage of cement packaging. Now it is necessary to kick the production of barrels and crates out of the wood processing plant, to say the wrong thing, to strip it off.

Jiang Cheng, the general manager of the timber mill, was almost angry, why do we do these low-level jobs that cost us all our body and energy every day?! Tie a bone to a dog, it can do it, right?!

The traversers rarely did not verify this mentions, and they completely agreed.

Let the Ming people do it!

Therefore, Director Song Shida decided to hand over this barrel and wooden box factory to the two ancients, and by the way, to verify whether the ancients could take on the heavy responsibility assigned by the traversers, and whether they could achieve the point of "you do things, I can rest assured".

The traversers can provide some staff, such as two Dutch coopers.

After the traversers brought the Dutch captives back to the city of Geranza, they were briefly interrogated and divided into three categories:

Mercenaries, all coolies, and the captives who had been working here would have taught them to obey the rules; Salesmen, depending on the situation, arrange different jobs; The technicians, especially those in the former shipyard, returned to their original positions and participated in the work of the traversers in building the sailboats.

Their trial has been postponed, but it is only a small change, and it is nothing.

The biggest change is that in the northern part of Taiwan, the season and the conditions of the production labor force are really not suitable for coal mining. Neither can the traversers.

The rain keeps falling, it keeps falling, so you can do it.

The traversers decided to forget it, and changed their plans.

If you don't go back, the Dutch won't be able to dig up coal even if they're dead, that's a waste.

Isn't it true that you traversers boast of the most complete plan in history?!

"Say, fuck, what are you running! Or how many people could die on the way? What a good laborer, dying on the road in vain! ”

Director Li Ziqiang is angry!

He yelled at the more than a hundred Dutch coolies who were considered qualified, and almost jumped up.

He Bin is also unambiguous, fluent in Dutch, and translated it into words. Even the tone is similar.

Director Li Ziqiang is not angry at this time, this ancient man named He Bin is a talent! Back then, if Lao Tzu had good English, he would have been Tsinghua in the morning.

In the end, Director Li Ziqiang had to select two carpenters with better skills from among these people to send to the Hekou base.

There's a shortage of people everywhere.

Director Li Ziqiang scolded angrily: "** Dutch, when will you be able to counterattack!" Lao Tzu is short of labor! ”

This sentence was too loud and the content was too inconsistent, which scared He Bin for a while.

The cooper gave it, and the rest of the people, Director Li Ziqiang, resolutely did not give it.

Sort it out for yourself, Ambassador.

Therefore, the director of the estuary base, Song Shida, decided to hand over this matter to these two ancients, no matter which one of them, go to Mingda 6 to recruit some people, and the salary is easy to say.

The ancients Li Si and Wang San lowered their heads and thought for a while, and said, "Song Dong, I have a ...... for Jianyì."

"But it doesn't hurt to say it."

"You see, it's not impossible to go to Ming University 6 to recruit people, not to mention the waste of time that comes and goes, the money for Ming labor here is still high, it's not suitable."

"Will the plan be released?"

Director Song Shida walked back and forth while thinking, is there any other way?

Li Si bent over and walked back and forth with small steps on his face, and said, "You think, this native hasn't run out yet!" It's suitable to use them, the wages are low, and it's okay to give salt......"

"Thou hast said: Those who can work are all there!"

Director Song Shida stood suddenly, what did you say before?

"Hey, that's before, now those natives who get paid for their wages have two days off a month, and when they go back to the village, they are arrogant, eating white rice every day, taking salt and cloth seriously. There are still indigenous ...... who ask me to work privately."

"Anything like this?! Why didn't you say it sooner? ”

Director Song Shida almost scolded.

"Aren't you busy these days?"

"Okay, don't talk about it, you want to contract?"

Song Shida suddenly felt that something was not right, the conversation just now was a little weird, who is the ancient?

Li Si bent over and shook his head, almost touching the ground, and said, "Thank you Song Dong!" ”

Director Song Shida was stunned, did I agree just now?

Thanks to old friends yezhongye, melage, drunk and not messy, let's pass, tfhy5523, yunshuixing for their support. Thanks also to the 114 subscribers for their support.

The book is actually a long folk song, its rhythm is the degree of reminiscence, the melody jumps gently, and the rests are hidden by the rhyme. The history of only a few hundred people is fictionalized here, and it tries to evoke the memories of many more people.

Matthiar said: "Reminiscing about the past life is tantamount to living again. "Writing and reading are both knocking on the door of memories, or both trying to live again.
