"Mr. Xiong, you have been in the industry for nearly 20 years, and I think you should have a good understanding of the country's policies.

Although the state does not currently have very mandatory requirements for VOCs in an industry, the state has obviously begun to guide in this regard. ”

“voc？”

"It's volatile organic compounds, and for your company, the volatilization of paint solvents is one aspect.

Another aspect is that during baking, there may be some by-products that volatilize into the air. ”

Xiong Wenbin was silent, probably recalling some recent national policies, and then summarizing to see if he could find some clues.

"Our company has a lot of exclusive processes, which have also been explored in the past 20 years, and all of a sudden, you asked me to change the process, no, this should be a complete change of a product.

I can't be sure that your company's products, after being used in my products, can produce products that meet our company's requirements.

It's a gamble, I hope you have a precedent for success, I've always held myself to the standard of a soldier, and the same is true for my own products.

I always put quality first, and at the same time to accept innovation, but this innovation, must know the roots. ”

It is normal to encounter Xiong Wenbin's opposition.

Any entrepreneur with normal performance will never easily change the production process of his products.

According to Xiong Wenbin, this is a gamble.

You don't know if the quality of the products produced according to this new process can meet the requirements and be loved by consumers?

This requires not only courage, but also the determination to break through.

But who would be so stupid in the face of the unknown!

"Mr. Xiong, let's not talk about changing things or not, let me tell you first, the advantages of solid powder coatings compared with oil-based coatings. ”

Xiong Wenming nodded, this thing is what it wants.

"Solid powder coatings, literally, can be known to be much better than paints in terms of environmental protection.

Mr. Xiong, you are also from a technical background, and all the materials of your current wheels should be aluminum, right?"

"That's right, since 2000, all the wheels we produce have been switched to aluminum alloy materials, and now we must be focusing on the family car market. ”

Aluminum alloy material is made of steel compared to iron material.

It's a bit too much, first, it's lighter, second, it doesn't rust, and third, it's more rigid and flexible than steel.

At present, 99% of the wheels of household cars on the market are made of aluminum alloy.

"Then your wheels, when they are taken out of the mold, still need to be polished, and the smoothness is definitely not enough when rubbing.

So at this time, the advantages of solid powder coating are revealed.

If you're spraying paint, you have to treat the rough surface, i.e. you have to apply a layer of primer, and the primer has to be very thick.

However, the solid powder coating is very strong, the rough surface of aluminum products, after spraying the solid powder coating, as long as the thickness reaches 120 microns, it can be more perfect masking, and there is no need to make a primer at all.

This is also the first and second advantage I want to say.

If you're spraying with oil-based paint, you'll have to go through at least four processes to coat the entire wheel, whereas with solid powder coatings, you'll only need to go through three steps.

From the company level, you have to have one less, which saves manpower and material resources, for a wheel, it may not be a lot, but for a year's volume, this is very large. ”

Xiong Wenbin nodded, but there was no other expression.

These two advantages alone were not enough to make him change his mind.

"The third advantage, the resistance to stone chips, is much better than paint.

The raw materials used in solid powder coatings are much longer than those used in oil-based coatings.

So the hardness of the whole coating is much stronger, and the car wheel, because it is very close to the ground, is often hit by small stones and small sand, so the more excellent hardness is definitely much better for the wheel. ”

Xiong Wenbin nodded again and again, although he didn't know whether what Zhang Xiaofan said was the truth or not, as long as he asked the people in the industry, he probably had an understanding.

Since Zhang Xiaofan dares to say it now, it proves that what Zhang Xiaofan said is at least eight points true.

This stone-resistant performance really interested Xiong Wenbin.

This thing is tested in the detection of the wheel hub, so if this solid powder coating is really used in the future, the detected effect, if it is really better than the oil-based coating, then it will indeed be of great help to the increase in sales.

"Fourthly, in terms of gloss and fullness, the paint can be said to be comparable, or even slightly higher than the oil-based paint.

However, in terms of corrosion resistance, this powder coating is much better than oil-based coatings, which is still from the chain length of the molecular formula. ”

Because the powder coating is in a state of room temperature, it is necessary to maintain a solid state, and in summer, it is necessary to prevent it from forming a lump, so its glass transition temperature is relatively high.

The high glass transition temperature is correspondingly due to the long molecular formula chain length of the product.

"I've seen it for a long time, and to be honest, I've heard of powder coatings before, but I haven't touched it.

I've been making wheels for nearly 20 years, so I'm familiar with paints.

But powder coating is really not touched, I still say the same thing.

You're trying to convince me to come up with something with real guns. ”

"That's fine, but now I have a bigger problem.

I don't know if the bear always wants to replace the entire process, or just the outermost layer of clear paint. ”

There are some manufacturers, because they want to maintain the advantage of the wheel in color, so they only replace the wheel clear paint.

And the middle layer of tinted paint, silver glitter paint, will not be replaced.

This is due to the advantages and disadvantages of oil-based paints and powder coatings, both in terms of metal powders.

In order to achieve the effect of metallic glitter on the surface of the wheel, the amount of aluminum metal glitter silver that needs to be added will be very large.

Generally, 10% is added, which is a disaster for solid powder coatings.

Solid powder coatings, for special reasons.

Therefore, if you add aluminum metal glitter silver, if you add too much of it, there will be a series of problems.

For example, when spraying, it is easy to form a build-up at the muzzle.

When the film is formed, it is very easy to form a non-dry surface, and the surface is very rough. Read the latest chapters, stay tuned
