Originally, I wanted to give them ten taels of silver per month, but the Jingshi University Hall has hundreds of genius students who are studying various researches, and each person is ten taels, which is tens of thousands of taels a year.

With the current capacity of the industrial association, it cannot afford to support such a large amount, and the construction of the industrial city will require money, and the research of steam engine ships in Matsue Prefecture will also require money.

So much silver has already been squeezed out of his teeth, and it is estimated that Huang Zongxi is going to cry out again and have no money.

Only when the industrial association goes out of Shuntianfu and extends industrialization to the entire north of Beizhili, and earns more silver, can these scientific researchers for the country and the nation barely live the life of small squires.

Walking out of the upside-down seat, Zhu Shun took twenty or thirty genius students to the bungalow that is usually used to record data.

With the current weather in the Ming Dynasty, people can freeze to death in winter, and there is not even a stove in the bungalows of these chemical geniuses.

Zhu Shun really couldn't imagine how the young students persevered in the face of such a difficult environment and made milestone achievements in chemical engineering.

Zhu Shun called a palanquin driver: "Go and inform Lizhouqiao, Uncle Ben doesn't care what he uses, even if any cement factory is suspended, a group of workers will be dispatched to build a new sulfuric acid dry distillation laboratory." ”

"Ondols, stoves, coal-heated blast furnace water towers, these infrastructure must be in place, and as for other anti-chemical issues, we must also come up with a feasible design."

The sedan chair man was about to leave the cold bungalow with his feet up, but Zhu Shun stopped him again and continued: "Tell Zhang Tao of the Industrial Department and ask him to give Uncle Ben an explanation." ”

"How did he act as the director of the Industrial Bureau, how did he let the students live such a hard life here, in addition, he asked Huang Zongxi to approve a large amount of salt, which had to be sent over every month, and an appropriate amount of salt should be added to the blast furnace water tower for bathing."

The palanquin man arched his hand, rode a Liaodong horse, and disappeared into the snowstorm.

After Zhu Shun explained this, there was a grinding 'zila' friction sound in his ears, and the chemical geniuses did not relax for a moment and began to take the initiative to record some data again.

Zhu Shun sighed in his heart and said calmly: "Things are not in a hurry, let's talk about the chemical defense of sulfuric acid, that is, the protection problem." ”

The toothless student said again: "Actually, the dean has been thinking about chemical defense for a long time, and he has looked through a large number of ancient books and found a cloth called Huohuan cloth. ”

"According to the records of "Liezi", "Bozi", and "Book of the Later Han", there is a kind of fire cloth that cannot be burned by fire, and the fire of Dean Jue cannot be burned, which should avoid the erosion of sulfuric acid."

"It's a pity that after the Han Dynasty, this kind of fire raccoon cloth was lost."

A kind of cloth that can't be burned by fire, Zhu Shun thought about it, it should be asbestos cloth.

Asbestos is indeed a good anti-chemical material, which can be used for anti-corrosion, heat insulation, fire prevention, heat preservation, etc., and has a wide range of uses.

Zhu Shun knows the origin of some asbestos mines, but he only knows the specific location of asbestos mines in a certain county, and a group of geography students who are good at exploration are needed to find them.

Asbestos cloth doesn't have to think about it for the time being, so I can only think of another way.

Zhu Shun had already had an eyebrow on the problem of chemical protection suits, and handed over the rubber drawings to Fuwang Shizi, in addition to the rubber gloves that can be used in most laboratories, there are also full-body rubber suits specially designed for the sulfuric acid dry distillation laboratory.

General natural rubber does not prevent strong acids and alkalis, Zhu Shun bought a full-body rubber suit from the hands of King Fu, and he liked the sealing.

The woven cloth, no matter how tight it looks, only looks, there are many invisible gaps.

The whole body rubber clothing can be used directly to hold water, and of course this problem does not occur.

With another thing that Daming has, it can be anti-sulfuric acid burning.

Raw lacquer.

The Ming Ordnance Bureau is used to brush the lacquer of arrow shafts and gun shafts, which is a natural anti-chemical material, in addition to weathering resistance, it is not afraid of any strong acid and alkali corrosion.

Lacquer does not belong to the monopoly of the imperial court, but it can also be bought, after all, many businessmen who make official hat chairs and eight immortal tables also use lacquer to brush on the tables and chairs.

With an idea, Zhu Shun wrote a letter and handed it to a palanquin driver, asking him to go to Xinningbo Mansion and buy a few barrels of raw lacquer.

The next day.

Several architecture students came to the vicinity of the sulfuric acid distillation laboratory first, exploring the terrain and looking for a suitable location for the construction of a new dry distillation laboratory.

Not long after, a master craftsman with several lacquer painters stopped at the door with two mule carts, all covered in raw paint.

Zhu Shun only needed a few barrels, but he didn't expect Xin Ningbo to order someone to pull two mule carts, it seems that Xin Ningbo attaches great importance to Zhu Shun's words.

Raw lacquer is also harmful to the body, Zhu Shun will not do it himself, so he called the craftsman: "Go and make a bucket of raw lacquer, put a piece of cloth in it and soak it." ”

The craftsman came over and hurriedly saluted Zhu Shun: "The little one has seen the uncle." ”

After getting Zhu Shun's order, the craftsman was not verbose, and began to mix raw lacquer, and he didn't know what consistency the raw lacquer needed from the industrial uncle, so he mixed seven or eight common consistencies.

The blending of lacquer is carried out in a cold bungalow, and Zhu Shun saw seven or eight kinds of lacquer with different consistencies, and then remembered that the lacquer has taken a long time to dry, and if it is really a kind of experiment, it will definitely waste a lot of time.

Zhu Shun took out an ingot and two taels of silver and rewarded it to the craftsman: "Good job, reward for you." ”

The craftsman hurriedly saluted, revealing a flattering smile: "Thank you, uncle." ”

Seeing the appearance of the craftsman, Zhu Shun, who used to be a craftsman, felt a lot of emotion in his heart.

After a few days, the lacquer-soaked cloth was almost all dry.

Zhu Shun spread the cloth soaked in raw lacquer of different consistencies on the hardwood table: "Pewter, go and get a bottle of sulfuric acid." ”

After a few days of contact, Zhu Shun knew that the name of the student who lost his teeth was Zhang Baiyong, and the name was much better than that of ordinary students, and it was quite meaningful, so he chatted a few more words.

Zhang Baiyong's father is not a farmer, he is an alchemist, this is his own statement, in fact, he is a charlatan.

Usually refining some mercury pills to cheat some silver from the hands of those little squires who are eager for immortality, but unfortunately he often walks by the river with wet shoes and is beaten to death by the squire.

Perhaps because of some family traditions, Zhang Baiyong is second only to Jiao Miao in chemistry among twenty or thirty genius students.

Zhu Shun took the sulfuric acid in Zhang Baipea's hand, poured it on the surface of the eight pieces of lacquered cloth, and began to observe the changes of the lacquered cloth.

The surface of the first four pieces of lacquered cloth showed slight penetration, and these four pieces of lacquered cloth were eliminated, and the last four pieces of lacquered cloth did not have any penetration, and all of them remained.

After the lacquer dried, there was not much damage to the body, Zhu Shun picked up four pieces of lacquered cloth, kept pinching and pinching, and finally decided to use the sixth lacquered cloth.

The fifth piece of lacquered cloth is still a little thin, and the seventh and eighth pieces are too thick, which will cause inconvenience when worn.

Zhu Shun put down the lacquered cloth and instructed: "Bai Yong, record the data of the sixth piece, sort it out and hand it over to the patent office of the Beijing Normal University Hall, you take 20% of the patent silver and give it 20% to this lacquer painter." ”

The lacquer painter didn't know what patent silver was, anyway, he had silver to take, so he hurriedly saluted Zhu Shun.
