Chapter 250 Chemical Factory ([-])
The combined equipment includes two sets of electrolyzers from the third workshop.

Electrolyzers are essential for the production of many chemicals.Caustic soda, chlorine and hydrogen can be produced by electrolysis of salt water; various chlorates, permanganates and persulfates can be produced by electrolytic oxidation.

In addition, wet electrolysis can refine metal copper, silver, gold and platinum.The electroplating and electropolishing samples in the factory are also realized through aqueous solution electrolysis.

With the three workshops, the traversing crowd can release a lurking gold-absorbing beast: the mirror.

As early as the 16th century before the appearance of the crossover, the Venetians had invented the cylinder method to make plate glass, and at the same time invented the tin amalgam method of using mercury to attach tin foil to the glass to make mirrors. This version 2.0 mirror makes Traditional metal mirrors are gradually reduced.

In history, silver nitrate was used to make mirrors, but it was not until 1835 that the German chemist Liebig appeared on the scene.He mixed silver nitrate with a reducing agent to precipitate silver from silver nitrate, and then attached it to glass to make a 3.0 version of the mirror.As for the real electroplated silver mirror, it will take nearly 100 years before the British will invent this technology.

And now that the third workshop has been established, Transit will soon be able to use the electroplating method to manufacture version 4.0 modern mirrors.

After blasting away the troublemaker gang headed by the emperor, Hong Xu, under the admiring eyes of the other three chemical dogs, began to gather workers to assign production tasks.

There are not many workers in the chemical plant.

Although as long as Hong Xu opens his mouth, three to five hundred people can be sent over if they speak, but this kind of routine doesn't work well in chemical plants—where accidents can happen if you turn a wrong valve, the more laymen, the more everyone dies. quick.

Therefore, in the newly opened chemical plant, excluding those who do rough work in the periphery, there are only 32 people who are qualified to be on the production line.

Among these 32 people, 20 are ordinary workers, and then there are 4 time-travelers with 2 apprentices each. No way, it's just so shabby.

Ordinary workers were brutally selected during the previous brutal production.These people belong to natural selection products with meek personality and good obedience—carefree, those who let themselves go are either disabled or dead.

And apprentices are even more precious.

Chemistry is an advanced science. If a person wants to get in touch with the fur of chemistry, he must have at least graduated from elementary school in basic mathematics.

Although the core education department of the crossing force: primary school, it has now expanded to 3 schools.But it has only been more than a year since everyone landed, and a large number of primary school students have not yet graduated.

Although the art class, music class, computer class, English class, morality and life class have been cancelled, but even so, it is impossible for students to graduate in mathematics within one year. Those who are kept for further study cannot be used as technicians.

Therefore, the technical talents that Hong Xu and the others needed could only be found among literate teenagers.This requirement is very strict: Ming people who are old and whose knowledge structure has solidified are useless. What Hong Xu and the others need are people who are around sixteen or seventeen years old, who are enthusiastic about learning and can endure hardships in factories.

Through the pre-screening of the workers' study rooms in every community, coupled with another big killer: the lure of high wages, Hong Xu and the others managed to find a group of apprentices before the factory was built.

Before they came to Dayuan, most of these apprentices were clerks and weavers in the Jiangnan area. The tide disaster that occurred near Hangzhou at the end of July this year bankrupted a large number of rural self-cultivators and urban working class in the rich areas of Jiangnan.

And as the area with the highest literacy rate in Ming Dynasty, these refugees who were robbed and transported from the south of the Yangtze River made it possible for the various departments under the crossing group to have a good year.

You must know that the quality of the weavers from the Jiangnan area is much higher than that of those mud-legged ones who only know how to farm.

Many of these medieval workers were literate, knew how to cooperate, and could endure boring industrial processes. With casual training, these people could almost seamlessly connect to the various factories under the jurisdiction of the kiln area.

Among the 8 apprentices under Hong Xu and the others, half were from the Zhihu family.

After convening the workers and apprentices to emphasize the precautions again, following Hong Xu's order, everyone put on imported orange protective clothing, and then everyone took their positions, started the equipment, ignited the boiler, and started the first operation of the Heishigou Chemical Plant. A trial production: sulfuric acid.

The production process of sulfuric acid is relatively simple and suitable for practice.Workers first pour the bright yellow sulfur lumps from the Taipei Volcano Group into the feeding port, and these sulfur lumps will be transported into the molten sulfur tank by belts.

The molten sulfur tank quickly heats the sulfur to liquid and sends it to storage tanks.During this process, the whole process will be accompanied by 0.5MPA steam in order to keep the liquid state of sulfur.

After liquid sulfur enters the tank, it will first be pressurized by the refined sulfur pump, then atomized by the sulfur gun, and finally sprayed into the sulfur furnace.

The environment required in the sulfur incinerator is also very harsh: the air must first be filtered, then pressurized by a blower, and concentrated sulfuric acid is absorbed and dried before being sent into the furnace cavity.

Next is a series of absorption and concentration procedures.Sulfur gas will circulate continuously in the absorption tower and nicotinic acid tower. After passing through the circulation tank, circulation pump, spraying, concentration and other processes, what finally enters the storage tank is the finished sulfuric acid with a concentration of more than 98%.

The entire technological process was completed without much disturbance under the operation of four traversing people.After all, Travelers came from the 4st century. Even on this simple sulfuric acid production line, there are still various monitoring, temperature control, and automatic management control terminals, and the operator does not need to go through a lot of trouble.

The finished sulfuric acid ended up in some thick glass jars.This is probably the most high-tech support that the kiln area can give to the chemical plant now, and the only thing left is those thick black reaction tank brackets and carts.

After the whole process was completed, Hong Xu and the others immediately turned into people's teachers, and immediately began to give lectures to the workers in various positions.

Hong Xu has no special requirements for ordinary workers.These semi-literate people do not have the concept of pressure, gas-liquid state, or pH value in their minds. They are actually the same as the workers on the assembly line of later generations, as long as they complete a few fixed actions on their posts. It is said that following the rules is the greatest success.

The focus is on those 8 apprentices.

These young people, who were trained as future section chiefs, workshop directors, and factory managers, followed the teacher respectfully, shuttled through the sea of ​​valves and pipelines, and listened to the incomparably detailed on-site lectures.They can ask questions at any time and get answered without tires.

　There are a lot of things going on recently, so I will do less for the time being. In addition, thank you for your long-term rewards and votes. After this busy period, I will retreat to the momentum, hehe!
