Traveling through the sword to engage in military industry

Compared to Li Yunlong's almost cheat-like progress, the progress of Zhu Zhendong, Chen Deren, Zhao Chengzhong, and Zhou Xueer was much slower.

They were responsible for the future industrial production of sulfuric acid. Ren Zhong got them several sets of beakers, crucibles, some sulfur ore, and even a small bottle of industrial concentrated sulfuric acid -- which Ren Zhong had initially obtained for them to use for nitrocellulose experiments.

There was also documentation on the industrial production process, but Zhu Zhendong and the others were obviously encountering many difficulties in verifying this process flow through experiments.

Therefore, as soon as they saw Ren Zhong, their faces were full of question marks, and they surrounded Ren Zhong with a hundred thousand whys.

(Don't ask what they said specifically, the author doesn't understand either, skip it, skip it!)

Fortunately, Ren Zhong had the foresight to hire a tutor in the main world to personally go through these experiments, and under the guidance of the teacher, he solved all the problems in the practical operation and successfully manufactured sulfuric acid under laboratory conditions. Although these things were not difficult for a chemistry teacher, it was because the chemical industry had undergone nearly a hundred years of development, and chemistry teachers had mastered the knowledge gained from the industrial practice of countless predecessors.

That's why he was able to guide Ren Zhong with ease to achieve a rough chemical experiment process for industrial sulfuric acid production.

In fact, even university professors would have to rack their brains to solve the problems encountered by Zhu Zhendong and the others.

Teachers with modern chemical knowledge are too scarce in this era.

Compared to Li Yunlong, Ren Zhong's operation obviously became more mysterious and taller in the eyes of Zhu Zhendong and the others.

Originally, they thought that the information provided by Ren Zhong was incorrect, so they couldn't achieve it. They had been hesitating between doubting themselves and doubting the information these days. As a result, after Ren Zhong's explanation, they realized that they hadn't thoroughly understood the details, and there were many flaws in the operation. In the final analysis, it was because they were too weak. After Ren Zhong's guidance, they suddenly became enlightened and gained a lot.

Zhu Zhendong and the others no longer had their original arrogance. Not only did they take notes of Ren Zhong's answers, preparing to review them from time to time, but Zhu Zhendong thought even further. He planned to unite everyone, based on the information provided by Ren Zhong, combined with Ren Zhong's current practical experience and guidance, to rewrite and refine the sulfuric acid process into a new textbook!

Of course, Ren Zhong didn't know what he was thinking now. If he knew, Ren Zhong couldn't help but give a thumbs up. Such a model employee who had already achieved self-motivation was really worthy of every boss's cherishment.

After spending some time pouring out the knowledge he had learned from his tutor to Zhu Zhendong and the others, Ren Zhong gained a wave of new admiration and felt very comfortable, and immediately felt that his efforts had not been in vain.

However, thinking of what he had asked Zhao Lidong and Wang Wenhui to do, this thing was even more difficult. How to learn to retell these two aspects of technology so that the Liangjian world could realize it made Ren Zhong immediately feel a headache.

The reason why he chose the lead-acid battery, this obviously outdated electric vehicle technology route, was because after Ren Zhong simply understood the manufacturing process of lithium batteries, he found that there was no basis for re-manufacturing them in the Liangjian world.

Lead-acid batteries had been invented in the Liangjian world for nearly a century. The current process of Lisai battery production seems very low in Ren Zhong's main world, but in the Liangjian world, it is basically the upper limit of technology that can barely be achieved! Once mass production is realized in the Liangjian world, it will probably be the world's top lead-acid battery.

Unfortunately, in China in this world, even if there is a "Provisional Patent Regulations", in Ren Zhong's view, it is useless. In troubled times, human lives are like grass, and high-end things like patents have no space for survival.

And Europe and the United States are also full of war now, Ren Zhong does not have the ability to register any patents in these places at this stage, so he will not consider this for the time being.

After all, some things, if he doesn't say it and seals the technology within the base area, even if someone wants to reverse engineer the finished product in the future, it will not be possible in the short term.

Therefore, Ren Zhong really doesn't know whether the millions of dollars invested in the battery factory can be earned back in the main world, but if it can be made in the Liangjian world, it will be a real profit!

With the start of the industrial process, there are too many places in the Liangjian world that use batteries. There is no space to transport them, and it is impossible for Ren Zhong to transport dozens of kilograms like an ant moving house, and Ren Zhong will not be able to meet the needs of the Liangjian world even if he is exhausted.

The happy mood only lasted for a short while, and Ren Zhong was re-pressed by the heavy burden on his body, and began to plan and design for the industrial production of sulfuric acid in the Liangjian world.

The production capacity of each set of cylinder-tower method is extremely low compared to the hundreds of millions of tons of sulfuric acid production capacity in the main world. According to the historical data Ren Zhong consulted, the sulfuric acid production capacity of the base area was only a few dozen kilograms per day in the early stage, and even after expanding the production capacity, it was only about a thousand kilograms per day. Compared to the wide range of uses of sulfuric acid, it is simply a drop in the bucket.

Propellant is just a simple application of concentrated sulfuric acid. Explosives, chemicals, fertilizers, pharmaceuticals, and many other industrial applications, such as ammonium nitrate, nitrocellulose, nitroglycerin, and lead-acid batteries, which Ren Zhong is currently working on, are inseparable from it. Some metals need to be treated with concentrated sulfuric acid oxidation to improve their corrosion resistance.

The production volume of sulfuric acid must be increased to one or even two orders of magnitude higher than in the original time and space in order to make the strength of the base area achieve rapid progress.

It is far from enough to rely solely on a production line that Li Yunlong is building in the clothing factory. According to Ren Zhong's plan, after the sulfuric acid industrial production line in the clothing factory is successfully tested, it will be built into a demonstration point, and then it will be promoted on a large scale in the base area. At least in the current few stable large base areas, cylinder-tower sulfuric acid production lines must be blooming everywhere.

Considering the Japanese devils' mopping up, the cylinder-tower sulfuric acid production plant will also be destroyed by the Japanese devils from time to time. The risk of the centralized production model being wiped out in one pot is too great. This also forces the base area to engage in a distributed production model. Just set up a set of cylinder-tower sulfuric acid production lines in one place, so that if the Japanese devils come and can't hold on, then a few grenades will blow up this production line, so that the Japanese devils get nothing.

As long as this group of skilled workers is transferred and protected in advance, according to Lao Li's construction speed as an infrastructure maniac, even if he starts from scratch to build a cylinder-tower from the earthen kiln, it will only take more than a month to build a new production line.

The main focus is on speed and efficiency!

The latest novels are first published on Liu 9 Shu Ba!

It is only 1940 now, and the strength of the base area is weak. Faced with the Japanese devils' mopping up, the leaders have to transfer frequently, so the production line cannot be fixed in one place.

Even Ren Zhong's newly discovered large cave can only be temporarily closed to avoid the limelight when the Japanese devils come to mop up.
