Alien Industrial Tyrannosaurus-Rex

　　 PTFE has a brother called polyvinylidene fluoride.

　　 Although they said they went out of the same category, their temperaments are quite different.

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

PVDF has good chemical stability and electrical insulation properties, so that the manufactured equipment can meet TOCS and flame retardant requirements. It is widely used in the storage and transportation of high-purity chemicals in the semiconductor industry. The porous membrane, gel, Separator, etc., are used in lithium secondary batteries, and this application has become one of the fastest growing markets for PVDF demand.

PVDF is one of the most important raw materials for fluorocarbon coatings. Fluorocarbon coatings prepared from it have developed to the sixth generation. Because PVDF resin has super weather resistance, it can be used outdoors for a long time without maintenance. This type of coating is It 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. For example, PVDF and ABS resin can be blended to obtain composite materials, which have been widely used in construction, automobile decoration, home appliance shells, etc.

　　 are some very boring materials.

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

　　 The research and manufacturing of raw materials is so boring.

　　 However, if there is no raw material, it is impossible to make all kinds of machinery.

　　 Europe and the United States have advanced technology and strong strength. The most fundamental reason is that other people's raw material technology has been leading for more than 30 years.

　　 It is very difficult for latecomers to catch up.

　　 Five minutes later, the first machine appeared.

　　 Its size is still very large, a full half the size of a football field.

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

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

　　 It would be great if it could be brought out.

　　 is definitely punching Nanshan Nursing Home and kicking Beihai Kindergarten!

　　 Wang Bu'an looked around.

　　 There is nothing unusual.

　　 The appearance of the large machine is quiet, without any sound.

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

　　 Continue to apply.

　　 Continue random selection.

　　 The second machine.

　　 mainly produces smart polymer gels. Mainly used in biotechnology. For him, it is of no use for the time being.

　　 Wang Bu'an shook his head secretly.

　　 I don’t have anything I want!

　　What do you want most? It is hard alloy, high temperature corrosion resistant alloy, titanium alloy, high performance copper alloy!

　　 It's a pity, Cybertron wouldn't give it to itself?

　　 There is no way, I can only bear it.

　　 Continue to apply.

　　 The third machine.

random selection.

　　 is actually a digital printing material.

　　 This thing is a bit interesting. The market price is also very expensive. But it is mainly used in consumer products. Little help to the machinery industry.

　　 Continue to apply.

　　 Continue random selection.

　　 The fourth machine is here.

　　 mainly produces low-expansion coefficient aluminum-silicon alloy materials and aluminum silicon carbide materials.

good stuff.

　　 is indeed a good thing.

　　Al-silicon alloy is also indispensable in machinery manufacturing.

It is a very important industrial alloy, which is widely used in aviation, transportation, construction, automobile and other important industries. It is also used to manufacture low and medium strength castings with complex shapes, such as cover plates, motor housings, brackets, etc. 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 an element of the third main group, and silicon is a semiconductor element, and the solid solubility between the two is very small.

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

　　 What is aluminum silicon carbide?

　　 It fully combines the different advantages of silicon carbide ceramic and metal aluminum, with high thermal conductivity, thermal expansion coefficient matching the chip, low density, light weight, high hardness and high bending strength. It is a leader in the new generation of electronic packaging materials, meeting the requirements of lightness and high density of packaging, suitable for applications in aviation, aerospace, high-speed rail and microwave fields, and is the material of choice for solving thermal management problems.

　　 Very abstract term, right?

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

　　 Of course, cans are definitely not.

　　Aluminum silicon carbide is very expensive, it is impossible 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 is not as expensive as titanium alloy.

　　 Continue to apply.

　　 Continue random selection.

　　No. 5 machine: mainly produces lithium niobate crystals. It is mainly used for various optical communications.

　　 Machine No. 6: LED phosphor. Mainly used for liquid crystal displays, weak lighting sources, luminous materials, etc. Both are in the field of civilian consumption.

　　 In general, bad luck.

　　 I didn't get the raw materials I needed urgently.

　　 Looking at the few remaining faith points, Wang Bu'an had to express regret and wait for the next time.

　　 Wait until I feel lucky.

"Jingle Bell!"

"Jingle Bell!"

　　 The phone and watch rang suddenly.

　　 is a very strange phone number. The display is from Qianzhou local.

　　 is connected.

　　 Cheng Kailong’s voice came.

　　 "Wang Buyan, come out." The other party said anxiously, "Remember, come alone, don't bring others."

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

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

　　 "Okay!" Wang Buyan agreed.

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

　　 is actually a certain highway exit.

　　 Cheng Kailong’s off-road vehicle stopped near the exit.

　　 Wang Bu slowly leaned the car up.

　　 Cheng Kailong's off-road vehicle started slowly, leading him all the way.

　　 After walking for two or three kilometers, Cheng Kailong's off-road vehicle finally stopped when he reached a place where there was no village in front of him and no shop behind.

　　 Wang Buan stopped in confusion, opened the door, but did not get off.

　　 He is upset.

　　What the **** is Cheng Kailong doing?

　　 This guy is mysterious, what the **** is he doing? Are you teasing yourself?

　　In other words, you don't go to study the 10,000-ton drive, but come here mysteriously to work as an agent. Are you a little bit unsuccessful!

　　 If the people of the whole country are like you, they don’t do their jobs, how can they realize the Chinese dream?

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

　　 "Let's talk, what's the matter." Wang Bu'an said coldly.

　　 "You get off the car. You can't say it in the car. It's not safe." Cheng Kailong shook his head and said.

　　 Wang Bu got out of the car in peace.

　　 The two walked to the wilderness on the side of the road. No one was around.

　　 "You are being watched by the people from Dongying." Cheng Kailong said word by word, "The mother and daughter of Yuanmeiren jewelry are staring at you."

　　 "They? Impossible..." Wang Bu'an was conditioned to deny it.

　　 planted!

　　 slander!

　　What is the relationship between yourself and Yuanmeijin jewelry?

　　 I can't fight them at all, okay? We never met. Why would you pull me and them together? Ridiculous...

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

　　 "Are they spies? Dongying's?" Wang Buyan immediately became interested.

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

　　 He likes the male protagonist in the spy movie the most.

agile.

　　 romantic and suave.

　　 It is clearly the undercover of the underground party, and it is clearly digging the corner of the party-state, but it is often regarded as the pillar of the party-state.

　　 Not only that, there are always beauties of all kinds around me.

　　 It's a pity that they are all TV shows.

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

　　 or five seconds of appearance.

　　 "Guess?" Cheng Kailong was actually sold out.

　　 "Extra high class!" Wang Buan answered without hesitation, "Yoko Nantian, Yunzi Nantian!"

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

　　 "Isn't it?" Wang Bu'an was slightly surprised. UU reading www.uukANAnshu.com

　　 "They are just commercial espionage. It has nothing to do with extra-high school."

　　 "Then maybe they were trained in the super advanced course. They specialize in the spy business. You must not take it lightly..."

　　 "Do you doubt our country's counterintelligence capabilities?"

　　 "Not really."

　　 Wang Bu'an had to shut up hesitatingly.

　　Do you doubt Guoan?

　　 of course is impossible.

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

　　 He pondered secretly.

　　The two Yuanmeis are actually commercial spies?

　　 Interesting!

　　 I wonder if they rely on sacrificing hue in exchange for information?

If so……

　　 can consider swapping!

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

　　If it can be realized...

　　 stop!

　　 stop!

　　 stop!

　　 Wang Bu'an squeezed his face hard.

　　How can you be so dirty?

　　How can you be so wretched?

　　 Anyway, those are also from the heavens, so how can they give them a chance to take advantage?

　　 Even if you want to have friendly exchanges, you should take the initiative!

　　 But, there are two of them.

　　I can't do it alone...

　　 "Did you feel left out recently? It seems that you haven't been taken seriously?" Cheng Kailong said faintly, "So that I feel that I am not able to meet my talents?"

　　 "Is it your deliberate arrangement?" Wang Bu'an suddenly realized, "I just said..."

　　 "How many pairs of underwear you wear, we all know very well."

　　 "I don't wear it at all."
