Zhang Ran is so proud, of course, there is a reason!

The mother acid is not good, and the lead plate is even more difficult, he knows it, but he can't stand the fact that he knows a little bit about everything in the era of the information explosion!

I know a little bit about everything, which is certainly not a good thing.

Take Zhang Ran's slight understanding of how to make sulfuric acid, he has to rely on himself to grope for sulfuric acid to make it, and he doesn't know when he will go.

But with such a professional as Deng Fang, plus his little understanding, he can roughly point out the direction of research......

Zhang Ran thinks that this can definitely achieve the effect of one plus one greater than three!

As soon as Deng Fang left, Zhang Ran called Wang Changtian over and asked him to pass the word to those landlords and quickly help him find someone who could burn pottery.

"Is our detachment going to open a pottery factory again?"

Wang Changtian stared at Niu Da when he heard this, and said in his heart that this is a fertilizer factory and a copper smelter in the detachment, and explosives and grenades are still being made in the mountains.

Coughing dryly, Wang Changtian took out an expression of the old-timers to teach the younger generations to be a man, and was ready to explain to Zhang Ran that being a man should do one line of love and one line, and don't engage in those things that are a hammer in the east and a stick in the west, otherwise I am afraid that in the end, I will not be able to please everywhere!

After getting along for a while, Zhang Ran knew what he wanted to do as soon as he saw Wang Changtian's expression, and immediately waved his hand and said: "I am preparing to open a pottery factory, but the purpose of opening a pottery factory is to open a fertilizer factory at the end!" ”

As soon as he heard that it was related to the fertilizer factory, Wang Changtian immediately swallowed the words that came to his mouth back into his stomach, and said with a grim face: "Then this matter of finding a potter who can burn pottery, captain, you don't have to trouble those landlords, I will find someone directly!" ”

"Do you know pottery burners? I haven't heard you say that before! "Zhang Ran is happy.

Wang Changtian rolled his eyes and said, "You didn't ask me before—besides, do you still need to know this pottery burner?" Those who carry burdens to exchange pottery for food have to come to every village here several times throughout the year, as long as they find them, are they afraid that they will not be able to find pottery? ”

“……”

Zhang Ran looked at Wang Changtian's back depressedly, and said in his heart that this guy, when he saw himself at the beginning, he was like a mouse seeing a cat, and now this has changed from a security chief to a secretary who handles the affairs of the people in the base, and the more the official is in charge, the more he is in charge, and his temper is also following the leader-he dares to choke with himself!

He didn't mind, though.

On the contrary, it is a good sign!

If Wang Changtian is his Zhang Ran's echo worm, if there is any emergency, it will be easy to catch blind!

And now, he will be able to deal with the complex situation in the future, instead of waiting for Zhang Ran to make a decision.

Therefore, as long as Wang Changtian's behavior did not violate the rules set at the beginning, and he was choked with a few words, he would never go to his heart.

"When the pottery burners come, let them burn some pottery jars, and try the tower jar method used by the Eighth Route Army to prepare sulfuric acid in history!" Zhang Ran pinched his chin and said.

The preparation of sulfuric acid by the tower cylinder method is an evolution from the most advanced tower method.

One of the biggest changes is that the lead chamber used to stop corrosion in the tower method has been replaced by an acid-resistant clay jar glaze.

According to historical records, in the most difficult period of the Anti-Japanese War, in order to prepare high explosives, the headquarters of the Eighth Route Army ordered the local military industry to overcome the problem of preparing sulfuric acid, because there were not enough lead plates to make lead chambers, which once brought the entire research process to a standstill.

In the end, it was the invention of the tower cylinder method that finally made sulfuric acid, and then began to manufacture high explosives for the production of various weapons and ammunition on a large scale, thus laying a solid foundation for the final victory.

Zhang Ran felt that the true eight-way people in history could use the tower cylinder method to prepare sulfuric acid, and there was no reason why he couldn't use the tower cylinder method to make it!

After all, this fake Eighth Road is also shining for the country, the nation, and the party's revolutionary cause!

Historically, the Eighth Route Army produced sulfuric acid, and then developed to be able to produce high explosives in batches and stably, which is already 40 years later!

With the large-scale application of these high explosives in the battlefield behind enemy lines, it has made it more difficult for little devils to move forward on the battlefield behind enemy lines, greatly relieving the military pressure on the frontal battlefield.

The successful preparation of sulfuric acid in the battlefield behind enemy lines can be said to be one of the biggest turning points in this national war of resistance against Japan!

"I will get the sulfuric acid out in advance, so that this turning point will come early, maybe I can win this war as soon as possible, so that many soldiers who would have died in the war do not have to die on the battlefield, so that more people can be saved from the poisoning of the Japanese army......"

Thinking about it like this, Zhang Ran suddenly felt that the responsibility on his shoulders was heavy, and his eyes became more and more determined.

The tower cylinder method can solve the lead plate problem, but the mother acid problem still cannot be solved.

This mother acid can't be used with just sulfuric acid - preferably high-purity concentrated sulfuric acid!

In this way, the sulfuric acid produced will also be of higher purity and concentration!

Only high-purity concentrated sulfuric acid can be applied to the preparation of various nitrifying high explosives, otherwise it will seriously affect the preparation and production of explosives.

Looking for the mother acid, Zhang Ran had already explained to Ma Feitian and others, and asked the landlords to help find clues.

But these things can't be found just by looking for them, so maybe when they will be found!

If you wait a few years to find the mother acid, then the daylily is afraid that it will be cold!

But when the diesel engine came back, he remembered an experiment he had done in high school on sulfuric acid.

Sulfur-containing gas, coupled with sufficient oxygen input, allows it to undergo high-temperature reaction in a confined space to form gaseous sulfur trioxide, and then injects water to obtain dilute sulfuric acid.

Since there are no other impurities involved in the whole process, dilute sulfuric acid will be relatively pure, as long as the evaporation reaction is carried out, concentrated sulfuric acid can be obtained, which can definitely be used as mother acid.

Sulfur gas, after the start of the copper smelter, with Deng Fang's help, Zhang Ran believed that it was not difficult to collect.

The difficulty lies in oxygen.

Of course, it is easy to produce oxygen from various chemicals, but there is nothing here, so this condition is not available.

The diesel engine reminded Zhang Ran of the easiest way to obtain oxygen, which is to split water by electric current to obtain hydrogen and oxygen digas.

As for the diesel engine power generation, it is easy to solve the problem of alternating current, and the use of copper wire around a few coils can achieve AC to DC......

And so the problem comes back!

There is a diesel engine, but there is no diesel!

"You can't let Lao Tzu learn from the little devil to dig up roots and steam root oil to generate electricity from now on, right?"

Zhang Ran was entangled.

As a last resort, he really didn't want to do such a thankless.

Of course, root oil can be used, after all, when the little devil was forced to go to Liangshan, he also thought about using root oil to fly a plane!

The problem is not whether the root oil can be used, but that there are too many disadvantages.

I am afraid that calling on the entire base area to organize people to set up boilers and start boiling oil, not to mention that they may not be able to supply this diesel engine to burn, the key is that there are too many carbon elements in the root oil, and the carbon deposition is serious.

There is such a diesel engine in the base, and he doesn't want to repair it every once in a while because of a carbon deposit problem, and it won't take long to scrap it!

"I have to find a way to get more diesel fuel and stock it up, and if I don't have to, I can just forget about the root oil......

Zhang Ran made this decision silently, and then took out a small notebook to record what things the base area urgently needed to prepare.

Mother acid, diesel, various engine oils, butter, coke, clay jars......

Zhang Ran looked at the dense things on the small notebook, and couldn't help but have a big head for a while, knocking on his head and wailing, saying in his heart that he was the supreme leader of the base area, and he was really a wretch!

These broken things, a few decades later, you can live with anything in a casual turn in the small county, and now in order to get these things, he is worried that his brain is hurting......

After wailing, Zhang Ran began to write down another thing that must be found, emery!

If the railway that the little devils are currently building outside the provincial city is completed, it will be only more than 300 miles away from the base area, which is the best source of high-quality steel, and even the blast furnace ironmaking will be saved.

It's a pity that the big railroad track can't be lifted at all!

If he finds enough emery, Zhang Ran thinks that he can make the grinding wheel, and finally find a way to make a simple cutting machine.

When the time comes, if you want to make the big railroad track that can't be lifted into a few sections, you can make a few sections!

Thinking of this, Zhang Ran slapped his thigh in annoyance, and said that he was in too much of a hurry to escape, and he forgot to tell Gu Xiangyang's guy, let them do no trouble on the railway every day, and let the little devil repair the railway first!

If the little devil railway can't be repaired, why don't you go to the wool of the little devil?
