Teflon has a brother called polyvinylidene fluoride.

Although it is said that they are from the same school, the temperament of the two is very different.

The application of polyvinylidene fluoride is mainly concentrated in the three major fields of petrochemical, electronic and electrical and fluorocarbon coatings, and is one of the best materials for pumps, valves, pipes, pipeline fittings, storage tanks and heat exchangers for the whole or lining of the fluid handling system of petrochemical equipment due to its good chemical resistance, processability, fatigue and creep resistance.

PVDF's good chemical stability and electrical insulation properties enable the equipment to meet TOCS and flame retardant requirements, and is widely used in the storage and transportation of high-purity chemicals in the semiconductor industry.

PVDF is one of the most important raw materials for fluorocarbon coatings, and the fluorocarbon coatings prepared from it have been developed to the sixth generation, because PVDF resin has super weather resistance, it can be used outdoors for a long time without maintenance, this kind of coating is widely used in power stations, airports, highways, high-rise buildings, etc.

In addition, PVDF resin can also be blended and modified with other resins, such as PVDF and ABS resin blended to obtain composite materials, which have been widely used in construction, automobile decoration, home appliance shells, etc.

It's all very boring stuff.

Those who can understand will naturally understand. Those who can't understand it are probably not interested at all.

The research and manufacture of raw materials is so boring.

However, without raw materials, it is impossible to manufacture various machines.

The most fundamental reason for the advanced technology and strong strength of Europe and the United States is that the raw material technology of others is more than 30 years ahead.

It is not easy for latecomers to catch up.

Five minutes later, the first machine appeared.

It's still huge, half a football field.

Of course, indispensable, there is also a robot elf.

It's a pity that these robot elves can only be active in the industrial park.

It would be nice if I could bring it out.

It's definitely a punch to the Nanshan Nursing Home and a kick to the Beihai Kindergarten!

Wang Buyan looked around.

Nothing out of the ordinary.

The advent of large machines was silent, without any sound.

By the time the people next to him noticed that there was a behemoth nearby, the machine was already firmly located in the wilderness.

Continue with the application.

Continue with the random selection.

The second machine.

It is mainly for the production of intelligent polymer gels. Mainly used in biotechnology. For him, it was of little use for the time being.

Wang Buan shook his head secretly.

I don't have anything I want!

What do you want most? Cemented alloy, high-temperature corrosion-resistant alloy, titanium alloy, high-performance copper alloy!

It's a pity that the planet Cybertron refuses to give it to itself?

There is no way but to endure it.

Continue with the application.

The third machine.

Randomly selected.

It's actually a digital printing material.

This stuff is kind of interesting. The market price is also expensive. But it is mainly used in the field of consumer goods. It will not help much for the machinery industry.

Continue with the application.

Continue with the random selection.

Here comes the fourth machine.

It is mainly used to produce aluminum-silicon alloy materials with low expansion coefficient and aluminum-silicon carbide materials.

Good stuff.

Good stuff indeed.

In the machinery manufacturing industry, aluminum-silicon alloys are also indispensable.

It is a very important industrial alloy, which is widely used in aviation, transportation, construction, automobile and other important industries, and is also used to manufacture low and medium strength castings with complex shapes, such as cover plates, motor shells, brackets, etc., and is also used as brazing solder. The alloy is a typical eutectic alloy with a simple phase diagram and no intermediate compounds. It has the advantages of good casting performance, high specific strength, and low price. Aluminum is the third main group element, while silicon is a semiconductor element, and the solid solubility between the two is very small.

Due to its light weight, good thermal conductivity, certain strength, hardness and corrosion resistance, and excellent casting performance, aluminum-silicon alloy is widely used in the automobile industry and machine manufacturing industry to make some parts used under sliding friction conditions.

What is aluminum silicon carbide?

It fully combines the different advantages of silicon carbide ceramics and metal aluminum, with high thermal conductivity, a coefficient of thermal expansion matched to the chip, low density, light weight, and high hardness and flexural strength. It is a leader in the new generation of electronic packaging materials, which meets the requirements of lightness and high density of packaging, and is suitable for the application of aviation, aerospace, high-speed rail and microwave and other fields, and is the preferred material to solve thermal management problems.

Pretty abstract term, right?

Think about the outer skin of a rocket, think about the outer skin of a missile, it's pretty much like that.

Of course, cans are definitely not.

Aluminum silicon carbide is very valuable and cannot be used to make cans.

Some parts of the aircraft can also be made of aluminum silicon carbide. Relatively speaking, the cost will be lower. After all, it's not as expensive as titanium alloys.

Continue with the application.

Continue with the random selection.

Machine No. 5: Mainly for the production of lithium niobate crystals. It is mainly used for various optical communications.

Machine No. 6: LED phosphor. It is mainly used for liquid crystal display, weak lighting source, luminous materials, etc. All of them are in the field of civilian consumption.

In general, bad luck.

I didn't get any raw materials I needed.

Looking at the few faith points left, Wang Buan had no choice but to express regret, let's wait for next time.

I'll wait until my luck is better.

"Jingle bell!"

"Jingle bell!"

The phone and watch rang suddenly.

It's a very unfamiliar phone number. The display is from Qianzhou local.

Put through.

Cheng Kailong's voice came.

"Wang Buan, you come out for a while. The other party said anxiously, "Remember, come alone, don't bring anyone else." ”

"What's the matter?" Wang Buan frowned and said, "It's so mysterious." ”

"You'll know when you come. Cheng Kailong said an address.

"Okay!" Wang Buan agreed.

He drove alone to the address that Cheng Kailong told him.

It's actually a high-speed exit.

Cheng Kailong's off-road vehicle was parked near the exit.

Wang Buan slowly leaned over the car.

Cheng Kailong's off-road vehicle started slowly and took him all the way.

After walking for two or three kilometers, Cheng Kailong's off-road vehicle finally stopped.

Wang Buan stopped suspiciously, opened the car door, but did not get out of the car.

He was in a bad mood.

What is Cheng Kailong doing?

What the hell is this guy doing? Is he teasing himself?

In other words, you didn't study the 10,000-ton drive well, but came here mysteriously to be an agent, aren't you a little out of business!

If the people of the whole country are like you who do not do their jobs and do their jobs, how can they realize the Chinese dream?

Cheng Kailong came to his window and motioned for him to get out of the car.

"Tell me, what's the matter. Wang Buan said coldly.

"You get out of the car. Can't say it in the car. Insecurity. Cheng Kailong shook his head and said.

Wang Buan got out of the car stupidly.

The two walked to the wilderness by the side of the road. There was no one around.

"You're being targeted by Dongying's people. Cheng Kailong said word by word, "The mother and daughter flower of Kite Beauty Jewelry are eyeing you." ”

"They'......re impossible," Wang Bu'an reflexively denied.

Planting!

Slander!

What is the relationship between myself and Kite Beauty Jewelry?

I can't fight with them at all, right? We haven't met at all. How could you get me involved with them......?

Immediately, he immediately remembered Chu Yulan's mysterious appearance. Doesn't she just want to borrow money for the kite jewelry?

"Are they spies?" Wang Bu'an immediately became interested.

In other words, spy movies have always been his favorite!

He likes the actor in spy movies the most.

Agile.

Graceful.

is obviously an undercover agent of the underground party, and he is obviously digging into the corner of the party-state, but he is always regarded as a pillar of talent by the party-state.

Not only that, but there are always all kinds of beautiful women around you.

It's a pity that it's all TV series.

If it is realistic, Wang Buan estimates that he can only live for two episodes.

Or maybe it's five seconds.

"Guess?" Cheng Kailong actually sold off.

"Special high class!" Wang Bu'an replied without thinking, "Nantian Yoko, Nanzao Yunzi!"

"You watch too much TV. Cheng Kailong shook his head and said.

"Isn't it?" Wang Bu'an was slightly surprised.

"They're just commercial spies. It has nothing to do with the extra high school. ”

"Maybe they're trained in a special high school. Specializing in the espionage business. You must not take it lightly......"

"Are you suspicious of our country's counterintelligence capabilities?"

"Not really. ”

Wang Buan had no choice but to shut up.

Suspicious of national security?

Of course it is impossible.

What does national security do. He couldn't even think about it.

He pondered secretly.

The two kites are actually commercial spies?

Interesting!

I wonder if they relied on sacrificing hue in exchange for intelligence?

If yes......

You might want to consider swapping it!

After all, every man has some evil thoughts in his heart.

If it is achievable......

Stop!

Stop!

Stop!

Wang Buan pinched his face hard.

How can you be so dirty?

How can you be so lewd?

Anyway, they are also people from the Heavenly Empire, how can they be given the opportunity to take advantage?

Even if you want to have a friendly exchange, you should take the initiative yourself!

But there are two of them.

You may not be able to do it yourself......

"Have you felt neglected lately, as if you haven't been taken seriously?" Cheng Kailong said lightly, "So that you feel like you don't have a talent?"

"Could it be your deliberate arrangement?" Wang Bu'an suddenly realized, "I'll just say ......"

"You wear a few pairs of bottoms, we all know that. ”

"I don't wear it at all. ”
