Return to the red age

PS: The chapter name of the previous chapter is wrong. You need to wait for the editor to change it. Don’t blame me if you can’t change it yourself.

But just think about it, because this won't happen overnight.

"High-pressure explosion-proof hose, this is a must. It will be widely used in the future." Liu Hai sent Sun Aiguo away and sat down to read a book again, thinking in his mind while reading.

High-pressure explosion-proof hoses mainly have several layers of mesh coatings of different materials, two, four, or six.

Modern methods generally use two layers of nylon mesh, two layers of steel wire, or other composite materials. In this way, the explosion-proof hose has sufficient elasticity and the overall product is relatively soft.

Those using all-steel wire are slightly less elastic, heavier, and the overall product is harder.

In fact, the entire product line is not complicated. The first is a nozzle mold with a heated extrusion device to squeeze the rubber particles into a tube shape. There will be the first coating at the outlet of the nozzle. Generally, it is a rotating one. A net-weaving machine has several wire posts wrapped with steel wire or nylon thread.

Then go to the next step to heat the rubber particles and the second layer of coating, so you need to add a few of these in the middle of several layers.

Of course, it sounds like a long story, but in fact, it only takes a few seconds from rubber particles to finished product. The key is the temperature of the mold, the running speed of the mold, and the speed of weaving the covering net, all of which are combined.

But with this set of equipment, Liu Hai felt that he could do it alone for at least a year.

"Where's the handicraft workshop?" Bangs then lowered the technical difficulty.

This belongs to the kind of workshop of Batie. This is very simple. First weave the film structure, and then put the film on a device similar to filling sausages. The sausage comes out where the rubber tube comes out. The rubber tube comes out. Just start covering.

This has a drawback, that is, it can only produce as many lengths as it wants at a time, fifty meters, thirty meters, etc.

Explosion-proof high-pressure hoses are involved in many industries, including airplanes, ships, trains, various mining machinery, and various processing equipment. It is a threshold that cannot be bypassed.

Liu Hai decided to do it because he was still young, but the 500-ton hydraulic press could only be hard-wired with seamless steel pipes for the time being.

This requires fixing the motor and everything else so that nothing can move.

Fortunately, the 500-ton hydraulic motor is not very static. In addition, the thickness of the rubber pad can be added to the seamless steel pipe joint to reduce vibration.

"Anyway, it's just to fool Big Brother. It won't be a big problem if you turn it on and run it for a few hours, or even ten days and a half."

The next day, Sunday, while others were still working overtime in the factory, Liu Hai went to Teacher Zhu's house to make up lessons.

"Brother, brother." Xiao Lin saw Liu Hai coming on a motorcycle and rushed out of the house in a flash.

Liu Hai took the little girl for a run in a sensible manner. The little girl talked about the kindergarten in a small mouth, and Liu Hai also agreed.

"Teacher, this is my homework. I'll go to Petrov's side first. I'll give you the car key and you can ride as you like." Liu Hai handed the homework to the teacher and said.

When the little girl heard this, she looked at her old father.

"Go ahead and come home for lunch." Teacher Zhu nodded.

On Petrov's side, several people gathered together when they heard Liu Hai coming. This time Liu Hai ordered some fried peanuts and some sugar from the factory canteen.

"That's great." Petrov took a big sip as he came up and said happily.

Chatting while attending class.

"Petrov, is it complicated to make explosion-proof high-pressure pipes?"

"This is not very complicated. The key issue is..."

"That's right, the design and manufacturing of the mold is the key, as well as the running speed of each part, etc..." Several foreign teachers drank a lot and replied with their tongues open.

Liu Hai was studying and asked at the same time: "Petrov, you guys are talking about the rotation of the excavator, how is it connected to the machine below."

"This technology is relatively complex and uses..."

Before noon, Petrov and the others went to sleep happily. There must be ears in this place, so Liu Hai asked about mechanical things.

I was enjoying the wind outside and smelled of alcohol. It was no longer hot in Kyoto in September. When I returned to the village tonight, Li Bing's clothes were ready, including new ones and old ones.

Liu Hai thinks that the current situation is very good. If you have a partner, there are men out there who don't want women. The more successful a man is, the more women there will be.

Marriage is very troublesome, so I can only mess around like this. It is impossible for Wang Hongmei to marry me anyway, and I am just right...

"It's this child. Is it my problem or Wang Hongmei's problem?"

We had dinner at the teacher's house at noon. At five o'clock in the afternoon, Liu Hai rode a motorcycle to Li Bing's place to load a sack of things. Liu Hai went to the supply and marketing cooperative to buy some things. Although Wang Hongmei was not her lover, she was My own woman will still feel pain when she should, but I can't guarantee that there will be no problem with the other supplies.

"Feeling a bit like Mistress Bao?" Liu Hai was riding a motorcycle and speeding on the road.

A motorcycle is fast. Liu Hai arrived home before it got dark. This time he took a day off and returned to the city the day after tomorrow.

"Xiaohai, you're back." When he heard the movement of the motorcycle, the first person to come was the captain.

"What's wrong?" Liu Hai was washing the pot, and when he heard this, he said.

"I don't know what it is. The chickens and ducks in the village have caused harm to the chickens and ducks, and they have also harmed several sheep. I told the township, and the township sent militiamen, saying it was a leopard. They guarded it for two days, but failed to guard it. The sheep were lost. Already." The captain said.

When Liu Hai heard this, he was not surprised at all. Now that the forest has been cut down, the animals at the bottom of the food chain are gone, and the only ones at the top of the food chain come to the village.

Liu Hai understood and said, "Uncle, where did the leopard come from?"

"We've looked for it. It's on the east side of the pass."

"That's fine, I'll go up the mountain to have a look tomorrow." Liu Hai nodded and replied.

"Zhong, I will send someone to accompany you tomorrow." The captain said.

Liu Hai said: "Okay."

Wang Hongmei heard the sound of the motorcycle and came in the evening. Looking at the clothes Liu Hai had brought back, she stretched out her hand to touch and asked, "Is this for me?"

"Take it back and change it. Put the old clothes and fabrics at home outside, otherwise it will be seen by others." Liu Hai nodded and said.

"Uh-huh."

"And you?"

"My factory over there needs to distribute clothes." Liu Hai thought, motorcycles will be put on the schedule, and three-wheeled motorcycles can be mounted. Otherwise, it would be scary to think about riding this in winter.

A breakup was better than a wedding, and they went back and forth several times. Liu Hai was recharging his energy when he suddenly heard the sound of a gong outside.

"I guess the leopard came down the mountain." Wang Hongmei said after hearing this.

"You continue to sleep." When Liu Hai heard the leopard, Wang Hongmei suddenly felt bad and stood up as she spoke.

Liu Hai rushed out with a rifle and a submachine gun on his back. When he came out, he found that it was already dawn, but Liu Hai did not go to see the excitement, but rushed directly to the pass.

After a quick march, we arrived at the pass. Standing on the pass, we could see the torches and the voices of people in the village far down the mountain. Then we took out a tactical helmet, but it was covered with a layer of camouflage cloth and the battery was placed on the waist. Inside the schoolbag.

"Two!" Soon Liu Hai found two shadows running from the bottom of the mountain. They looked quite big, and they were one behind the other. They were swimming leisurely. They were also holding a sheep in their mouths. The sheep's carcass was still hot. It's so clear in thermal imaging.
