Sail across the sea

Chapter 283 Don’t talk nonsense about this.
Yun Zhongming negotiated with Gao Fan through the Science and Industry Committee to come to Maple Forest Research Institute to help. The main purpose was to ask Gao Fan to help him improve the resin formulas in several special coatings.

Coatings are a large category of chemical products, but the idea of ​​developing coatings is not complicated.Most coatings consist of four basic ingredients: base resin, solvent, pigments and fillers, and additives.The development of coatings is based on these four basic ingredients.

The base resin is used to form a coating on the substrate, and the pigments and fillers are bonded together through the resin.Common base resins include natural resin, phenolic resin, alkyd resin, nitrocellulose amino resin, polyester resin, epoxy resin, polyurethane resin, acrylic resin, etc.

The function of the solvent is to dissolve the resin during the manufacturing and construction process of the paint. After the solvent evaporates, the resin will re-solidify to form a film-like coating on the construction surface.

Pigments and fillers are added based on the function of the paint.Among them, Xinglong Paint Factory's reflective paint adds a large number of glass microspheres with reflective effects to the resin.

Glass microspheres, also called glass microspheres, are the same material as the glass that people use daily, but they are very small in size, roughly 0.15 to 0.3 mm in diameter. The shape is irregular and can be a standard sphere, or Can be an ellipsoid.

High-quality glass microspheres can be manufactured through special equipment, and their raw materials are various waste glasses.

The glass microspheres used in the production of reflective coatings do not have high quality requirements. Their source is fly ash produced in the production process of coal-fired power plants or fertilizer plants.

In order to make coal burn more fully, power plants or fertilizer plants will crush the coal, mix it with clay to make briquettes, and then burn it.The high temperature generated during combustion will fuse the minerals in the clay into silicate glass, which will form a large number of glass microspheres when cooled.

It was under Gao Fan's guidance that Chen Xingquan took away a large amount of fly ash from a local power plant without spending a penny, and then extracted glass microspheres from it as fillers in reflective paint.

The last component in the coating is various additives, including wetting and dispersing agents, leveling agents, defoaming agents, adhesion promoters, etc., which need not be detailed here.

Yun Zhongming found Gao Fan because he saw the reflective paint from Xinglong Paint Factory.However, the products Yun Zhongming's team is currently developing are not reflective coatings, but several special coatings used in the military for waterproofing, anti-corrosion, camouflage and other purposes in buildings.

The functions of special coatings are mainly achieved by changing fillers and additives.In these aspects, Yun Zhongming's team has made significant progress.However, they have encountered some difficulties in developing resin for coatings and are looking for solutions.

At this time, Yun Zhongming accidentally obtained a reflective paint sample from Xinglong Paint Factory. The resin used in it has the advantages of wear resistance, cold resistance, high temperature resistance, etc., and judging from the quotation of the paint, the cost of the resin is undoubtedly Very low, which aroused Yun Zhongming's interest.

As for asking Gao Fan to drop what he was doing and come to help because he was interested, and also directly said, "Don't leave once you're here," this was the prerogative of the military industry system.

After listening to Gao Fan's question about whether to stay or not, Yun Zhongming didn't care that it was better to talk about the project first.Anyway, if Gao Fan comes here this time, he won't be able to leave until he finishes the current project.

It is not that easy to develop a modified resin based on Yun Zhongming's idea.Even after several rounds of experiments and tests, it would take a year and a half.So he had enough time to brainwash Gao Fan and make him realize that staying at Maplewood Research Institute was the best choice in life.

"Forget it, let's go to the laboratory first. I'll introduce you to the engineers in our laboratory. Let me tell you, these people are the top experts in chemical industry in the country. You can learn anything from them and it will be better. The lessons you listened to in college classes were much better." Yun Zhongming boasted.

"Okay, I was just thinking of asking the seniors for more advice." Gao Fan replied humbly.

In his mind, there was another calculation:
Since your people are all top experts, why did you bother to find me?
No matter how high your level is, can you beat my time traveler Golden Finger who is 40 years ahead of his time?
Of course, now that I'm here, I won't hesitate to wave my golden finger a few more times.Being able to improve the country's military technology by one or two levels can be regarded as an explanation to the Space-Time Management Bureau, right?

With this thought, Gao Fan followed Yun Zhongming with a smile and walked towards the experimental building in District [-].

Maple Grove Research Institute was founded in the 50s and received strong guidance from Soviet experts in its early days.The experimental building in District [-] has a typical Soviet style. The exterior facade looks rough and majestic. Each floor inside is more than three meters high and has wide corridors.As Yun Zhongming walked among them, listening to the footsteps echoing in the corridor, Gao Fan seemed to have heard the BGM of "Holy War" in his ears.

On both sides of the corridor are laboratories, with signs hanging on the doors and numbers written on them, which shows that the concept of confidentiality has penetrated into every detail.

However, for the personnel within District [-], the division of labor in each laboratory does not need to be kept secret, and in many cases different laboratories need to exchange information and share technological breakthroughs.

Gao Fan was a person who passed the political review, so Yun Zhongming didn't have to hide anything from Gao Fan. As he walked, he introduced the research scope of each laboratory to Gao Fan, which also meant to test Gao Fan's knowledge.

"This is Laboratory 03. Their current research focus is on absorbing materials. Do you understand the role of absorbing materials?"

"Reduce the reflection of radar waves and use it to enhance the stealth performance of aircraft and warships."

"Yes, yes, the gap between us and Western countries in this regard is still relatively large. Last year, we proposed cooperation in this field to the United States, but they did not agree."

"I saw in a magazine that the United States is developing a new generation of fighter jets, with stealth being the most important performance indicator. They are not willing to disclose this advanced technology to us."

"You're right. Look, this laboratory here is currently doing research on insulation materials. Hehe, what they are doing is not the rubber on the wires you have at home."

"Teflon?"

"..."

"I just made a wild guess. There is a lot of research on this abroad now, and many uses in the military field have been disclosed."

"You can't go out and talk nonsense about this..."

"That's for sure, I've just been educated on secrecy."

"The things they do in the previous laboratory are relatively unpopular. I guess you have never heard of it."

"what?"

"Photoresist."

"Photoresist!"

Gao Fan stopped for a moment, looked at the number "08" on the laboratory door, and thought slightly.
