Anti-Japanese War: Many children bring blessings, we, Lao Li, have become a great power

Chapter 29, a small reveal, Zhang Wanhe was shocked: One day without seeing Li Yunlong is like three autumns! (Additional update!)

Exchange for something?

Zhang Wanhe immediately became excited:"Is it Sakata's Saguan sword?"

"Do you want a Japanese mother-in-law?"

"Hahaha...fuck you!"

The two laughed loudly

"Back to business! Li Yunlong took out the information for making smokeless gunpowder:"Come on, Lao Zhang... take a look!""

"What's this?"

Zhang Wanhe opened it doubtfully, and his expression was immediately stunned.

"How to make smokeless gunpowder?"

"Where did it come from?"

"I invented it……"Li Yunlong:"How about it? Can this thing be exchanged for a thousand military uniforms?""

"this……"Zhang Wanhe is hard to handle!

So, he handed the information to Li Tianming, the director of the arsenal:"Let's see if this method is feasible?"

Li Tianming was overjoyed when he saw it.

"It turns out that our breakthrough point is here... No wonder……"

"Haha... I didn't expect that this is the barrier to the production method of smokeless gunpowder!"

"Ha ha……"

Li Tianming is so happy!

In fact, the arsenal is also conducting research on smokeless gunpowder, but it has been unable to break through the bottleneck.

Research has stalled.

I have even thought of stopping research.

Your energy is limited, so there is no need to waste time. did not expect……

"Haha, I really didn’t expect that! Li Tianming was very excited:"Captain Li, you wrote this recipe!""

I can't believe it.

A guy with muddy legs can actually defeat the technology of smokeless gunpowder!

Li Yunlong nodded.

"We military workers are so impressed! As for the excitement, Li Tianming still had some doubts:"It's just that using a water tank as a container...is it possible?"

Li Yunlong:"Whether it works or not, won't you know if you try it?""

"Guard, go and bring me the water tank from the cooking class!"

"Yes, Minister!"

Soon, the water tank and the necessary materials including the ceramic pipes were ready.

Li Yunlong was not unambiguous and started working on the spot.

He used a hammer and wedge to cut out the required holes in the water tank and put a pair of water The cylinders are buckled together, and the joints are sealed with lead water to form a"reaction chamber". The entire reaction device consists of five reaction chambers, which are connected in series with lead pipes. These reaction chambers are collectively called"towers".

First The first tower and the last tower are equipped with small pieces of coke as a filling for damping.

There are two devices at the front: one is a box riveted from iron sheets.

Sulfur is ignited in it and blown with a bellows to produce sulfur dioxide gas. , and the excess air is introduced into the front tower.

The other is a cast iron kettle, which is filled with nitrate and sulfuric acid. After heating, nitrogen oxide gas is produced, which is also introduced into the front tower.

"After the"equipment" is started, the things flowing out from several towers are poured back and forth manually, and sulfuric acid should be obtained under the first tower. The dilute sulfuric acid is made and flows out from the small holes under each tank. After evaporation and concentration, Obtained white and transparent sulfuric acid.

After the operation, Li Tianming and Zhang Wanhe were stunned.

"My dear... Li Yunlong, you are a fucking genius!"

"The brain is so useful! Looking at the sulfuric acid, Li Tianming was completely impressed:"Captain Li, you can't imagine the technical barriers that our engineering department cannot break!""

"It was broken by you!"

"You have made a huge contribution to the research and development of our military industry!!"

"Li Yunlong informed, thank you!

Li Yunlong:"Director Li, this is serious. We are all for the revolutionary cause!""

"It’s just a different division of labor!"

"Without your silent dedication of the first generation of military workers, we would not have the weapon to fight the enemy bravely!"

"You can copy this method and carry out mass production!"

"must! must!"Li Tianming said excitedly:"In this way, we have solved the problem of high concentration of sulfuric acid!"

"The remaining nitrocellulose and charcoal can be easily solved!"

"As long as smokeless gunpowder is produced, the power of our bullets and cannonballs will increase by more than one level!

Li Yunlong continued:"That's right!""

"If you want to increase the production of sulfuric acid, Director Li, you can do this……"

Stack 4 water tanks on top of each other and open the middle to form a tall tower with a larger volume.

Seven or nine such towers are connected in series with ceramic tubes and glass tubes with larger diameters.

The front and rear towers are filled with acid-resistant porcelain tiles.

Ancillary equipment has also been enlarged accordingly

"In this way, the daily output of sulfuric acid will increase dozens of times."

Ten times?

Li Tianming's eyes widened with disbelief on his face.

Li Yunlong:"Of course, in the follow-up, you can still do this……"

"Porcelain bowls are placed crosswise in each reaction tower in the middle to make the reaction more complete."

"Use the flue to introduce the hot smoker that heats the iron can, increase the temperature of the front tower from outside the tower, and once again increase the efficiency of acid formation in the front tower.……"

After listening, Zhang Wanhe and Li Tianming fell in love with Li Yunlong, who had already admired him.

"Lao Li, when did you become a top student?"

"When talking about this professional terminology, it’s like a set!"

"Is this still the Li Yunlong I know?"

…… ps: The normal update has been completed, and the next step is to add more updates. Is anyone still watching? I haven't received a single flower today. So pitiful/

Please give me flowers, monthly tickets, and evaluation votes! Some wealthy person can give me a reward! I really want to break out in the tenth update!
