"Manager He, do you think that is the boss?"

He Qian was sitting in the office, discussing something with a technician, and suddenly the technician said to He Qian.

I thought I didn’t go directly to He Qian after joining the powder coating company, so I was wandering around the workshop.

Take a look at the work appearance of employees, their mental state, and the cleanliness of a workshop, whether the tools are arranged neatly, and whether there is any missing tools?

Does anyone have any staff not equipped with masks and earplugs?

Li Wei is very strict in preventing and treating occupational diseases. After all, powder coatings are plastic particles. If they are inhaled into the lungs, they will always have more or less impact on their bodies. Although it is not the source of pneumoconiosis, it will definitely have an impact on their health.

Therefore, you must wear a mask of 95 and also wear it in a standard way.

The earplugs are because the sound of the entire workshop is relatively loud and has exceeded the national decibel number, so earplugs must be worn to relieve it.

He Qianchao, who was discussing technology in the office, took a look outside the window and found that it was really Li Wei.

"Let him see, the boss likes to look around anyway.

If you change it here, 89 grams may be a bit too much. You change it to 87 grams and then do an experiment."

"OK."

Sure enough, it didn't take long, about five or six minutes later, Li Wei came to the office.

"boss"

"I came here today to ask, where has the development of low-temperature curing coatings been progressing?"

"Now we can do it at about 150 degrees, and it takes about 18 minutes."

"This is far from it, what accelerator do you use?"

Why can normal coatings cure under low temperature conditions?

It must be because of the accelerator.

Anyone who has studied chemistry should know that adding promoters can make the chemical reaction more intense.

In other words, adding accelerators can change the conditions of chemical reactions.

The accelerator mentioned by Li Wei is an accelerator that reduces the reaction temperature.

“Imidazole”

This is a very commonly used accelerator. It can not only be used indoors, but also outdoors.

"Have you ever thought about using special low-temperature curing epoxy? Dow Chemical should have it, and you can ask someone to ask.

If there are curing agents, imidazole-modified phenols can be used.

These two combinations should reduce the curing temperature to about 130 degrees, and the time should be between 25 minutes and 30 minutes.

Did you use pure epoxy?”

There are roughly three types of powder coatings.

Pure epoxy type, the main film-forming substances are epoxy plus curing agents.

Epoxy polyester type, the main film-forming substances are epoxy and polyester.

Polyester type, the main film-forming substance is polyester curing agent.

Pure epoxy has a high cost because no matter when, the price of epoxy is basically much higher than that of polyester.

However, low-temperature curing coatings are also sold at a high price, so don't worry.

"The dicyandiamide curing agent is used for pure epoxy."

"Isn't there another way to accelerate the double clean-up?"

"The goods have not arrived yet, I ordered a pack of samples. I don't know when they will be able to deliver them."

"Try it and take a look, I'll try it anyway.

We make this low-temperature curing coating to develop wood coatings.

You also know that the board will deform when it encounters high temperatures, so your temperature is best to control it to around 120 degrees, and it cannot exceed 130 degrees at most.

And during this period, you can also study how paint sprayed on wood can show better leveling.

Provide you with some ideas

The first thing you can do is soak the wood in water. Of course, there must be conductive materials in this water.

The second is to add a layer of conductive material on the wood. This material must have good viscosity with the wood and will not affect its performance after reaching 120 degrees."

"I've written it down, and I feel that this paint has a very wide range of applications."

“Yes, the biggest application point should be in the home furnishing industry.

Nowadays, there are fewer and fewer log furniture, and people are more willing to use some granular boards or multi-layer plywood.

This kind of board needs to be surface-treated, and this is our business opportunity.”

We often see that white wooden boards have a smooth surface, roughly flat luster, and good thickness. The surface of this board may be painted, of course, paint, or powder coating.

This is not important. As long as the conductivity problem is solved and the low-temperature curing problem is solved, then powder coatings can be used.

Although the surface effect may be a bit unsatisfactory, it is cheap.

The cost of spraying paint and spraying powder is completely different, and the price of paint is obviously much higher.

Of course, the more you go back, the more you have the advantages of powder coating.

Because environmental protection problems will become more and more serious, the country will pay more and more attention to this aspect.

Then many manufacturers have no way to spray paint, so about 10 years later, various places will carry out oil-to-powder conversion.

That is, reduce or eliminate the use of paint, and switch to environmentally friendly paint, powder coating or water-based paint.

However, one thing that must be said is that water-based paint may not be less pollution than paint, so when it comes to environmentally friendly paints, powder coatings are the first priority.

"You can order more raw materials and let them get more samples. I think we should grasp it. The competition for conventional paints will only increase.

We should also play some new tricks, and don’t keep staring at traditional things and keep thinking about them.

I won’t talk about wood and plastic, and then the most common paint with glass as the carrier should be sprayed on the wine bottle.

We must follow up on this point, and almost no one realizes that there can be painted on the bottle.

If we enter this market first, then this moat will be quite solid.

What's the reason?

Because this market is actually very small, most wine bottles are transparent.

But there are a small number of manufacturers who like colored wine bottles.

For example, white wine and red wine.

Let’s rule out the white ones first, that’s the red ones. I think this is our opportunity.

They still use paint now. If they switch to powder coating and then put on environmentally friendly hats, it will definitely be a surprise."

He Qian didn't know how to respond, he thought it was better to do technology.

The boss's idea seems a bit imaginative.

The glass bottle is sprayed with powder coating, and it always feels a bit whimsical.

But when I think of my boss’s past record, it seems that this is not impossible.

But if you don’t know why, it always feels a little strange.

"Wine bottle?"

"I didn't expect it, it didn't matter, I have the chance to see it in the future.

Our goal is that as long as it can be made of paint, we must be able to do all the powder coatings.

This is something that all powder people want to do!”
