"Is there any explanation for this?"

"At present, there are basically three types of coatings in the market.

Oil-based coatings, water-based coatings and solid powder coatings.

The advantages and disadvantages of the three coatings are actually more obvious.

Oil-based paints are naturally polluting the environment and have a great impact on human health.

In the case of solid powder coatings, in terms of metal coatings, in terms of ease of spraying, they are slightly inferior.

In the case of water-based paints, the overall performance is much worse. ”

Xiong Wenming nodded, although he didn't know much about it before, but now that Zhang Xiaofan has accepted it, he has a preliminary understanding.

"Does this have anything to do with what you just said, just changing the clear paint, or changing the whole process?"

"If you switch all the processes, then all your paints have to be replaced, all of your paints are changed from oil-based paints to powder coatings. ”

"Then it must have been all changed, and if it is changed, it must be changed comprehensively!

Since you just said that, solid powder coatings have so many advantages compared with oil-based coatings, and for the environment, they are environmentally friendly and have no harm to the human body.

If you want to change it, you can simply change it completely, which not only saves process time, but also contributes to the environment. ”

Xiong Wenbin said very simply, obviously, this retired soldier still retains the style of a soldier, either he doesn't do it, or he wants to do it best.

"Mr. Yang, 99% of the wheels on the market are all shining silver.

However, solid powder coating is just in the flash metal coating, which is a relatively weak weakness. ”

This made Xiong Wenbin even more puzzled, just now you said that the powder coating was so good, and now you say that there is a weakness.

"Mr. Xiong, the glitter silver paint of the wheels is made of aluminum silver paste, and the content is very high, basically more than 10%.

This does not have much effect on paints with organic solvents, but for powder coatings, the impact is significant.

Powder coating does not use aluminum silver paste, but uses solid metal aluminum powder, a metal aluminum powder, the content of which should not exceed 4% in powder coating.

There will be a problem with powder, 4% metal aluminum powder, after adding can not achieve the effect, can not be like paint, the whole layout looks silvery. ”

This time, Xiong Wenbin knew.

"What you're saying is that if you use powder coatings, you won't be as effective as the oil-based paints that we're using today.

The metallic glitter isn't strong enough, and the metallic sheen isn't enough?"

"Yes, exactly. ”

Xiong Wenbin hesitated, if the current effect cannot be achieved, it means that his product is worse than the previous surface effect.

At least it looks worse, and the wheel looks beautiful on the outside because of its metallic glitter effect.

If the metallic glitter effect of powder coating is not as good as that of oil-based paint, is it necessary to use it?

"It's about a few percent, compared to the oil-based paints we are currently using. ”

"About seventy percent, but ordinary people should not be able to see it, only professional technicians can distinguish the difference. ”

Xiong Wenbin sighed, it didn't make much sense to say this.

Ordinary people can't see the difference, so what's the point of saying that?

Since ordinary people can't see the difference, it means that there is no difference, after all, wheel users are still ordinary people.

"And what do you mean?"

"I'm afraid that your company's products will not pass the acceptance of the car manufacturer. ”

"You're not wrong about that, they have very sharp eyes, and basically they can check out the slightest flaw and return it.

So the metallic glitter effect you are talking about is not as good as oil-based paint, I didn't think of it just now, but you said it. ”

For Zhang Xiaofan to consider him, Xiong Wenbin was touched once.

"So can you try to raise the product to this level?"

As soon as Xiong Wenbin's words came out, Zhang Xiaofan gave himself a thumbs up in his heart.

The potential meaning of this sentence is that if the effect of Zhang Xiaofan's products can reach the effect of the current oil-based coatings, then the production process can be converted and Zhang Xiaofan's products can be used.

This is simply a natural sound, and it can be seen on his face that Zhang Xiaofan is very happy.

"Mr. Xiong, I think so.

I designed three spraying processes for the entire wheel industry.

There are three coats of paint in total.

The first layer, primer.

The function of this layer is to fill, increase adhesion, and reduce the cost of the whole process.

I know that your aluminum wheels, when they first came out of the mold, the surface was very rough, and they needed to be polished once, and the surface was also rough.

Therefore, it is necessary to fill the coating, in order to flatten the entire surface, so as to better pave the way for the subsequent coating.

The price of this layer of paint is around 40 per kilogram.

The second layer, the coloring layer.

This layer is the shimmering silver powder layer, and the effect of this layer is to make the entire wheel look metallic.

The third layer is the overshadow layer.

That is, the clear coat, the effect of this layer, improves the gloss, and there is also a protective effect. ”

Xiong Wenbin nodded again and again, the powder coating spraying process designed by Zhang Xiaofan is quite reasonable for aluminum wheels.

"Your process is very reasonable, it is very in line with the process of aluminum wheels, compared to oil-based paints, your powder coating process is one layer less.

This does have a great throttling effect on cost saving and manpower saving.

Now that you've proposed this process, what level have you reached in your research and development?"

This is the CEO with a technical background, they can often ask very good questions, and sometimes they don't understand technology, so they don't come over to negotiate.

So sometimes a boss who doesn't understand technology isn't necessarily a bad thing.

"At present, we have developed two layers, the first layer and the third layer, and we can basically come up with finished products.

The middle layer of coloring, at present, due to the lack of technical depth, the effect is not as good as that of oil-based paint.

In fact, all the powder coating companies in the world have been committed to research, closer to oil-based coating products, but it is still a little bit worse.

This is not just a problem for one of our manufacturers, but a problem for all powder coating manufacturers.

Recently, however, I had an idea, and I decided to personally lead a team to study this glittering silver paint, and I must achieve this effect of more than 90%.

I don't know if Mr. Xiong is willing to give us this opportunity, but when the time comes, I will make a model and ask Mr. Xiong to verify it himself. ”
