Li Wei is staying in the office here, and the workers are busy, so He Qian does the experiment by himself.

Not long after, Long Zheng called.

"Mr. Li, good news!"

"Oh? What's the price?"

“20,000”

Li Wei was shocked by this. It was only a few days ago, and the price before the festival was 17,000 yuan.

In three to five days, an increase of 800,1000 per day.

Too scary.

This is the raw material, this is the chemical raw material.

This is also why the futures market can make people want to die.

Because you don't know where the price will be in the next moment, maybe you will enter the billionaire level overnight.

Of course, for Li Wei, it's just a matter of making millions.

Unlike those who are powerful in the futures market, they make hundreds of millions of dollars in profits, and of course the same is true for losses.

However, there is no futures market for epoxy. If there is one, Li Wei is ready to play, which is definitely quite exciting.

"Do you think it can be shipped now?"

"I can't say this well, mainly depends on how Mr. Li chooses. I think it may exceed 21,000, because there is no news about the Korean company.

And after the repair, there will definitely be some trial operation, maybe one month or half a month.

Of course, this price is not absolute, and it may be a pullback."

"You can start contacting now. Is there a very out of stock in the market now?

The price I offer here is only 22,000, and I can pay the shipping fee here.”

"There are still a little bit of goods on the market, so I'll try to contact you."

"I have 94 tons from Hengtai. There are 100 tons from Shanyuan."

"I see."

The price of 194 tons of epoxy is more than 4 million.

Li Wei is very excited now. The assets he earned in his previous life are estimated to be more than 4 million.

But now, the money you earn is equivalent to half of your assets in your previous life.

No wonder in my previous life, when I sat together and talked to those big bosses, they often talked about not their own business, but the business in the world.

We are talking about the raw materials market. No wonder they say it doesn’t matter if they don’t make money in their own business. As long as I can maintain the high speed of my company and as long as I can ensure that my raw materials use remains at a high level, I can use this to negotiate with the upstream, whether it is to lower the price or the account period, it is very favorable.

Those large paint companies purchase a large amount of preparations when the price is low, and do not replenish raw materials when the price is high, and then replenish them when the price is low. In this way, the overall cost will decrease and the price difference of their own products will be released.

When the company becomes stronger, Li Wei will definitely do the same.

But now my company uses the raw material epoxy very low, and the amount per month is only a few tons.

In the eyes of those raw material suppliers, they almost don’t like the amount of a few tons. Not to mention the right to bargain, even if you have a account period, they are compressed very tightly.

Not long after, He Qian walked in.

"Boss, I just measured it and the average particle size is 65."

This particle size is slightly thin and needs to be made thicker.

Li Wei's testing equipment is very comprehensive, with two particle size detectors, one water dispersed and the other laser, and the two are worth 200,000 yuan, such as salt spray detectors, 100-meter knife, pencil hardness detectors, viscosity detectors, photoaging detectors, etc.

Because Li Wei's company now has a relatively large amount of recycling materials, it is necessary to conduct very strict testing of the products, otherwise the company's reputation will be affected once problems occur.

"Get a pipe and try the fluidized barrel."

"OK"

The spraying method of fluidized beds (fluidization barrels) is completely different from the electrostatic spraying method.

Fluidized bed: A large number of solid particles are suspended in the flowing fluid, so that the solid particles have some apparent characteristics of the fluid.

To put it simply.

It is to fill the powder coating with a lot of air to make it feel like very dense dust in the container, which can flow in the container.

Therefore, when the pipe enters the container from top to bottom, the inner and outer walls of the pipe can be contacted with the powder coating.

After the pipe is preheated, the surface temperature reaches more than 100 degrees. The temperature of more than 100 degrees can be melting and adhesion of powder coating. Therefore, when the pipe is raised, powder coating is attached to the inner and outer surfaces. Then the pipe is followed by the assembly line and then baked for a period of time before coming out, and the paint is painted.

If electrostatic powder spraying is used, the inner wall of the tube cannot be sprayed. The first one is due to the air flow relationship and the second one is due to the electrostatic relationship.

A pipe is several meters long and charged powder particles driven by airflow may accumulate at 20 cm and will not spray on the inner wall of the pipe, far away.

Half an hour later.

"Get me a flashlight, forget it, let's go to the lab!"

I don’t know if it was a lazy cancer attack, but Li Wei also wanted He Qian to help him go to the laboratory and bring the strong light flashlight over.

But as soon as he said it, he decided to go to the laboratory.

"From the light of the strong flashlight, we can see that the inner wall of the pipe is still relatively uniform. Let's test how much thickness is just now?"

DidiDidi...

He Qian tested seven or eight positions.

"Average about 90"

"Okay, it proves that your method is still good. You can continue to do experiments.

If you want to add filler, reduce filler, or change it to other colors, you can try it out, which will have an impact on the thickness of the coating.

The most important thing is to adjust the particle size to 100-120 microns.”

The other company requires 120 microns and 90 microns when the laboratory comes out. The technical goal should be to achieve it.

However, you can also add or reduce the filler, and then change the particle size of the powder coating accordingly to see if the cost can be reduced.

Filling is filler.

Powder coatings have 4 major components: polyester, curing agent, pigment filler and additive.

There are many ways to reduce costs, one of which is to add filler.

Because the price of fillers is generally between one to three pieces, while for other polyesters or curing agents, the price is usually above 13 pieces.

However, this method reduces costs, one very important point must be paid attention to.

The technical parameters must meet the customer's requirements.

For example, it must meet the requirements or even exceed the requirements in terms of adhesion, weather resistance, bending resistance and other properties.

Of course, many customers do not have a technical standard.

Then you must meet your company's technical standards.

This is very important.

No matter how much lower your price than others, no matter how reliable your relationship with your customers is, your product will still be the one that can help you speak in the end.

Li Wei has a deep understanding of this point. Bad money drives out good money. This situation is very common in the future. Whether it is celebrity traffic or public trust, they will bring traffic to bad money drives out good money.
