After the explanation was completed, Zhang Xiaofan was unwilling to stay for one more minute.

It's still a little awkward to stay with Xia Churui, so if you don't see each other for a while, it will be much better at that time.

The news from Liu Pingfeng's side has not yet come, and there is no news about the charter of the speedrun radiator, which makes Zhang Xiaofan have a sense of urgency.

Especially on the side of the speedrun radiator, according to Zhang Xiaofan's guess, they should start to be anxious, after all, if the cost of competitors drops suddenly, then it will be a disaster for themselves.

In China, the price war is still the mainstream means of competition, so if the cost of competitors falls, then its selling price will definitely be lowered, which is not good news for a manufacturer.

However, there is quite bad news for Zhang Xiaofan.

Zhang Xiaofan's paint has a problem.

As long as there is a problem with any product, you must solve it quickly, otherwise it will have a great negative impact on the reputation of your product.

So Zhang Xiaofan rushed to Tianhui Ceiling Company in a hurry, hoping that there would not be too many problems.

Otherwise, Zhang Xiaofan will definitely not be able to stand this loss, Zhang Xiaofan doesn't know what is wrong now, it stands to reason that it has been tested, and there should be no big problem.

But this is the case with solid powder coatings, there are too many uncertainties in it, involving all aspects of physical and chemical knowledge, and it is difficult for Zhang Xiaofan to calculate the problem.

When I arrived at the ceiling of Tianhui, the company had completely stopped work, and if Zhang Xiaofan's product problem was not solved, I am afraid that it would not be able to start work for the time being.

"Mr. Li, I'm very sorry, I don't know what's wrong now, let's take a look at the product that went wrong first!"

Li Feiyun's expression was solemn, this time the problem was a little strange, Zhang Xiaofan's products did not have this problem at the beginning, that is, three days ago, it was fine, but the products produced now, not to mention being first-class products, this is a defective product, you and people feel faceless, and it is really not eye-catching.

"Okay, this time the problem is a bit strange, I've never encountered it before. ”

"When did it first appear? Did it start with the first box, I usually check these paints every three boxes, so if there is a problem, I guess it should be all of them, not just a part"

"That's why I feel weird, the first two days are sprayed very well, and the products can easily reach the best grades, but since three days ago, there have been problems intermittently, some of them are excellent products, and some of them are not as good as defective products. ”

The two of them came to the side of the problematic product, and after reading it, Zhang Xiaofan frowned.

There must be something wrong with the paint, not a general problem, the paint is mixed with some other things, it should be a floating agent containing silicone oil.

The float is actually a thing that uses the different tension of the surface of the paint, and after mixing with the paint, it forms an orange-like pattern, and the surface is like a water wave, which is very beautiful.

However, there are many kinds of floaters, and their surface tension will be different, and the surface tension of floaters with silicone oil is very small.

Therefore, when this floater is added to the flat type of paint, it will cause large shrinkage porosity on the surface of the paint.

Now on the whole ceiling, there are more than a dozen shrinkage holes that are deeply visible, which is very unsightly to the appearance, and these holes are the most important performance of the paint, and there is no room for exertion at all.

It is because of these shrinkage holes (you can see the holes in the substrate with a diameter of about 0.5 mm) that the oxides in the air are very easy to approach the substrate, so that the bottom is easy to rust and oxidize, starting from these small holes, the remaining parts will slowly peel off the paint, and finally cause the entire panel to rust.

We often see that the guardrail of the house starts to rust from the weld, then slowly spreads around, and finally the whole guardrail will be corroded by rust.

"Zhang Gong, what do you think is the reason?"

Zhang Xiaofan can't yet determine whether it is caused by the float, but it is 80% to 90% likely that it should be this.

"That's it, Mr. Li, let's open a few new boxes and try it, I think, find out where the reason is?"

"Okay, try it right away"

Li Feiyun personally selected ten boxes, new powder coatings.

Before I started to try it, the spray master next to me began to complain.

"Is this your powder coating? Why is the quality so poor, there have always been such problems in other people's homes before, and several have been used, but your family is the worst. ”

Zhang Xiaofan was full of smiles, but he had already put a big exclamation mark on this person in his heart.

There is definitely something wrong with this person.

"Master, I don't want to have such a problem, no, as soon as I heard that there was a problem, I rushed over immediately.

Now let's not talk about why this problem came out, the biggest thing we need now should be to solve this problem. ”

"Anyway, I won't spray, you can find the two of them!"

This master's words, not only Zhang Xiaofan's brows furrowed, but even Li Feiyun was quite unhappy, no one wants to do this kind of thing.

Now we just need to solve the problem and let the company return to normal production, and then slowly negotiate why this problem is happening, and there are some compensation issues.

"Master Jin, call everyone over and cooperate with Mr. Zhang to solve this problem as soon as possible. ”

It turned out that this person's surname was Jin, and when he heard Li Feiyun say this, he had no choice but to call three other spraying masters, and everyone started work together to see what the problem was.

Zhang Xiaofan carefully observed the behavior of the four people, let him remember all the problems he found in his heart, and did not tell Li Feiyun.

A total of 20 samples, after all came out, Zhang Xiaofan observed, holding his chin with his hand and looking serious.

Among these 20 templates, there are good ones, some bad ones, and some unsightly ones.

Zhang Xiaofan basically has the bottom in his heart, and his workers will definitely not deliberately add this kind of floating agent containing silicone oil in the past few days, the main reason is that Zhang Xiaofan has not entered this raw material at all, so the problem must be within Tianhui Ceiling Company.

Zhang Xiaofan glanced at Master Jin, squinted his eyes slightly, he didn't know if he was weak or what, he didn't dare to look at Zhang Xiaofan.

Of course, when a man sees another man, the other man will never look at him, especially if he is not familiar with him.

Of course, this point was completely ignored by Zhang Xiaofan, he always felt that there was something wrong with this master surnamed Jin, and from the beginning he came in, this master targeted him, and he didn't bring him a green hat, but when it came to the appearance of this master Jin, Zhang Xiaofan definitely didn't have any thoughts, and he didn't have any interest in cuckolding him.

"Mr. Li, let's talk while walking, basically I have found the reason.

Let's see how this matter can be solved so that you can resume production as soon as possible. ”

Li Feiyun nodded, and the two of them prepared to go in the direction of the office.
