?? Now I don't know, a few days later, the lacquer painter looked at the five hundred taels of silver in front of him, and almost fainted.

The lacquer painter also knew that he couldn't keep such a windfall, so he gave Zhang Baiyi a hundred taels of silver, and asked him to help intercede and replace it with Zhu's spinning machine.

Where did Zhang Baiyong dare to ask for his silver, and after he shirked it, he asked his classmates in the Beijing Normal University Hall at the Patent Office if he could change it to Zhu's spinning machine.

It is useless for the imperial relatives to come over to intercede, but the Patent Office attaches the highest importance to the Ming inventors of invention patents.

Immediately sent someone to the Beiping Machinery Bureau, snatched a batch of Zhu's spinning machines handed over to a certain uncle, and handed them over to the lacquer painter at the normal price.

The lacquer craftsman was freed from poverty and became a small factory owner in an industrial city, which stimulated the students of the new schools in various counties and set off a boom of invention.

The problem of chemical protective clothing has been solved temporarily, and if it is really solved, it is necessary to wait for the prince of Fuwang to transport a batch of rubber protective clothing and brush it with a layer of raw paint with appropriate consistency, and the problem of chemical protective clothing will be completely solved.

The problem of sulfuric acid storage tanks also needs to be solved, Daming and the glass produced by Europa, the quality is uneven, and it is easy to burst again.

The explosion of the sulfuric acid tank is one thing, and the sealing problem also needs to be dealt with, otherwise the sulfuric acid extracted at the risk of high hazard is easy to volatilize.

The sulfuric acid tank could not be disposed of here, so Zhu Shun rode a Liaodong horse to Xing'anbo's private kiln, and the glass factory had not yet been built, so he first used the porcelain jar as the sulfuric acid tank.

Liaodong Malaysia stopped upstream of the Zhu's cement factory, and in order to save money for mules and horses, Xing'anbo has relocated all the private kilns to the vicinity of the ore steam factory.

When the housekeeper heard the news from his subordinates, the industrial uncle came, and he didn't care about drinking rice wine around the stove, so he called all the stewards to greet the industrial uncle.

Xing'an Bo has a courtyard here, and the housekeeper knows the friendship between the little uncle and the industrial uncle, so he asks his subordinates to prepare wine and food, and takes the industrial uncle to the other courtyard.

Zhu Shun didn't come over to get drunk with money, he went directly to the largest private kiln: "Go and find the best craftsman." ”

Zhu Shun sat in the main hall of the humble private kiln, and without taking a few sips of tea, an old craftsman who was not confused about his age walked in and saluted the industrial uncle: "The villain has seen the uncle." ”

Zhu Shun roughly conceived a sulfuric acid porcelain jar, and said: "Uncle Ben needs you to fire a porcelain jar, the whole body of the jar is a cylinder, the mouth of the jar must be threaded, and the lid of the porcelain jar must also be threaded, and the two must be able to be screwed together. ”

When the old craftsman heard that he was going to burn his old profession that he had been doing for decades, he was a little less restrained: "Uncle, how big do you need to fire?" ”

The capacity of the sulfuric acid tank is about ten liters, and Zhu Shun instructed: "One bucket is enough." ”

The old craftsman received the order, bowed, and hurried out to begin firing the sulphuric acid tank.

Zhu Shun waited in the private kiln for a day, and the housekeeper brought the sulfuric acid tank, which made him a little crying and laughing, in order to show his craftsmanship, the appearance of the old craftsman was Hongzhi yellow glaze with unicorn ornamentation.

The surface of the sulfuric acid tank should be labeled, writing the sulfuric acid concentration, production location, and production date, and it is best to fire it into a simple white porcelain jar, which should not be too fancy.

Zhu Shun took this yellow-glazed unicorn pattern porcelain jar, poured in a full amount of hot water, and put his palm on the threaded position to feel it for a moment, and no heat overflowed.

There is no problem with the quality of the sulfuric acid tank, and Zhu Shun instructed: "In the future, this kind of porcelain jar will be fired into simple white porcelain, and a thousand will be fired first and sent to Jiao Miao." ”

The housekeeper saw that Uncle Gong was satisfied, and his posture of being careful to accompany him relaxed a lot, and he saluted with a smile: "Uncle, don't worry, the little one will send the porcelain jar to the third young master as soon as possible." ”

The porcelain jar of water was just to test the breath-holding effect of the threaded porcelain jar, and further tests were needed in order to be foolproof, so Zhu Shun rewarded the housekeeper with ten taels of silver and left here.

Back in the sulfuric acid distillation laboratory, Jiao Miao had already gotten up from bed, wrapped in a cotton suit, and sat in a cold bungalow recording some data.

The third disciple Jiao Miao's palm had been severely burned, and he still insisted on recording the experimental data, Zhu Shun was unhappy at the same time, but his heart was also full of relief.

Only by adhering to this spirit of scientific research can we build Daming's chemical system from scratch and build it little by little.

Zhu Shun put down the sulfuric acid tank in his hand and called Jiao Miao and the chemists who recorded the data: "Go and bring the stored sulfuric acid over a bucket." ”

Sulfuric acid is of great significance to Daming's chemical system, and the strategic secrecy level belongs to the same level as Dongfeng Rocket, and only Jiao Miao has the key to the concrete warehouse.

When Jiao Miao was not in the distillation laboratory, he would hand it over to Zhang Baiyong for safekeeping, and personally brought all the sulfuric acid: "Master, it's not enough." ”

The efficiency of sulfuric acid produced by dry distillation is extremely low, only 10% conversion rate, and the sealing of sulfuric acid storage is very poor, and the whole Ming Dynasty only has about five or six liters of sulfuric acid.

Zhu Shun took over more than a dozen glass jars, carefully poured the remaining sulfuric acid into the sulfuric acid tank, and said calmly: "The two most important problems in sulfuric acid storage are the corrosion prevention of the sulfuric acid tank, and the other is the sealing. ”

"Porcelain has good corrosion resistance, and the storage of sulfuric acid in the future is mainly based on porcelain jars, and after screwing on the screw cap, a layer of raw paint should be brushed on the mouth of the screw cap."

Zhu Shun screwed the screw cap on, asked the tower man to bring a bucket of thick lacquer and brush it in the gap between the lid mouths, and took out a pre-made label: "This square paper is called a label." ”

"Before each tank of sulfuric acid is put into storage, the concentration of sulfuric acid, the place of production, and the date of production must be written on it."

In order to make the chemical engineering students more aware of the explanation just now, Zhu Shun picked up Jiao Miao's hard brush and recorded it in detail on the label.

As long as the chemical products are leaked, the harm and danger caused are extremely great, and Zhu Shun took the trouble to explain it several times.

It wasn't until the first batch of sulfuric acid tanks was sent over, and each chemical student practiced three or four times to confirm that no link in it would be missed, that Zhu Shun left here with confidence.

Before leaving, Zhu Shun repeatedly instructed Jiao Miao to pay attention to the storage of sulfuric acid, and to discuss the construction of the new dry distillation laboratory with the talented students of the Infrastructure Construction Department.

Thinking that Jiao Miao was focused on how to improve the refining method of sulfuric acid, and his temperament was relatively wooden, he estimated that he would not take the initiative to find a genius student from the Infrastructure Construction Department, so he handed over the construction of the new dry distillation laboratory to Zhang Baiyong.

Zhu Shun instructed some details and walked out of the sulfuric acid dry distillation laboratory full of chemical experiments.

Glanced back.

Jiao Miao and the genius students of Beijing Normal University Hall got together and argued fiercely.

Full of fanaticism.

Zhu Shun rode on the Liaodong horse, but sighed.

The first martyrs of the Industrial Revolution.

Maybe.

will arise from here.
