Li Feiyun's answer was still to consider it, and Li Chunhua accepted it when he saw it, so he left not long after.

From beginning to end, Li Chunhua never mentioned it again, doing the matter of deputy supplier.

He knew that if he mentioned it again, it would definitely arouse Li Feiyun's disgust, so that this matter would be ruined, but now he will accept it when he sees it, which may have an unexpected effect.

Obviously, Li Chunhua's words did work, and not long after Li Chunhua left, Li Feiyun thought about it and felt that it was more reassuring to call Zhang Xiaofan.

"Zhang Gong, tell me about the reason why this paint film is falling off in pieces? I'll see if there are any other problems on our side!"

Zhang Xiaofan thought it was very strange, this matter was obvious, it was a chemical added in the cleaning pool that hindered the combination of paint film and substrate.

I don't know what Zhang Xiaofan is about this, because there are more such things.

The combination of the coating and the substrate.

The main forces are generally divided into two types.

The first type of physical force

The surface of all substrates looks flat, but in fact, there are many potholes in the microscopic aspect, and the coating is liquid in the molten state during the curing process, so it can be easily drilled into these holes, and then a physical hook is formed.

The second is the chemical force.

There is mainly the force of hydrogen bond formation, and the force of van der Waals force is actually very small.

Therefore, when there is a chemical substance that can destroy this physical or chemical force, the paint can not adhere to the substrate, thus forming a large piece of peeling.

"The reason for the formation of this large piece of paint is actually more complicated.

It may be the cause of the substrate, or it may be the cause of the paint.

However, all kinds of reasons need to be analyzed through the actual situation.

Naturally, it is impossible to generalize. ”

That's all Zhang Xiaofan can say, although I don't know why Li Feiyun suddenly asked this.

"And what is the reason for the peeling of the paint this time?"

This time, Zhang Xiaofan began to be a little vigilant, he had already analyzed it with him last time, and after cleaning the cleaning pool, there was no more paint falling off.

This is well understood, and it is indeed a problem in the cleaning pool.

But Li Feiyun suddenly asked this question today, so this one is worth studying.

"It's obvious that someone has put some kind of chemical in the tank, but I don't know exactly what it is. ”

"Alright, okay, I see. ”

Li Feiyun hung up the phone after finishing speaking, which made Zhang Xiaofan even more inexplicable.

And there is a very bad feeling, this is a sixth sense, men's sixth sense is actually sometimes more accurate than women, Zhang Xiaofan really doubts that someone is saying bad things about people behind their backs.

Li Chunhua is a little proud now, and today he feels that he has played perfectly.

As long as Master Jin can complete his instructions today or tomorrow or the day after tomorrow, then the list of Tianhui ceilings will be secure.

Such a list of Tianhui ceilings is not small for the entire Guanlan Group, not to mention that for Li Chunhua, the significance is extraordinary.

After all, it's about whether he can establish your own paint company in the future.

After all, he has been in Guanlan Group for nearly 20 years, and he is still very confident about the R&D capabilities of Guanlan Group.

Most of the recipes are leveled left and right, and will not be too high on the market.

The main reason why Guanlan Group is still thriving is because of the role of the brand.

If Li Chunhua opens a solid powder coating company by himself in the future, then the importance of formula is very obvious.

This is the truth that he thought about for a long time to understand, and this is why she has been holding on to Zhang Xiaofan.

The direction of the event designed by himself, in the end, Zhang Xiaofan must be unable to bear it, and then exert another pressure on himself, which will naturally make Zhang Xiaofan, a young man, comply.

And soon there will be another thing that will make Zhang Xiaofan anxious.

The more he thought about it, the more he felt that things would definitely go his way, so his mood was getting better and better, and he could even hum a song when he walked.

Basically, all colleagues can feel that Li Chunhua is in a very good mood.

But Zhang Xiaofan was very depressed, he always felt that something was going to happen, but he didn't know where it would happen.

The reason for this is Li Feiyun's phone call, so Zhang Xiaofan is ready to visit the ceiling of Tianhui again.

The first is to have a good chat with Li Feiyun, and the second is to see if anyone has put chemicals again.

As long as this person is caught, then everything will be revealed.

Then Zhang Xiaofan was shackled by another thing.

Someone reported that Zhimei New Materials violated the pollutant discharge.

Zhang Xiaofan felt that things seemed to be a little unexpected, and his own beautiful new material did not belong to paints and coatings.

Therefore, there is no way to talk about pollution, and there is basically no possibility of air and water pollution in the production process of solid powder coatings.

The only pollution can only be said to be noise pollution, but Zhang Xiaofan has taken this into account when designing the factory.

It is difficult to hear the roar of the machine even if you stand on the edge of the factory, which is due to the proper use of sound insulation materials, and the sound in the workshop is difficult to hear.

And the sound that workers hear during production will not exceed 65 decibels.

This is a reasonable range, and it is difficult to want a completely soundless machine.

Then this matter is obvious, that is, someone wants to disgust Zhang Xiaofan and overwhelm him.

Zhang Xiaofan even wondered if Li Feiyun's incident would be related to the current reporting incident?

So now Zhang Xiaofan you can't go to the ceiling of Tianhui.

He has to stay in the company because he is a corporate legal person.

Wait a minute, and immediately there will be a staff member from the Environmental Protection Bureau who will come and conduct a sampling inspection.

Zhang Xiaofan has a lot of things to prepare.

Business license, production license, pollutant discharge permit, and so on.

It may be delicious and delicious.

At least a pack of cigarettes is indispensable, after all, they come all the way, and you should give a small gift if you feel reasonable.

Whether to receive it or not is their business, and whether to send it or not is a question of whether you understand human feelings.

The EPA's work efficiency is quite fast.

I heard that I received a report in the morning, and then I started to contact Zhang Xiaofan at noon, and called Zhang Xiaofan at one o'clock in the afternoon, and I was almost there, but I didn't know where to go, and Zhang Xiaofan sent someone to pick it up.

Zhang Xiaofan sent someone to politely pick them up.

Then two people started testing.

Since the sewage outlet could not be found, the water quality test was also missed, but a bottle of sewage was still collected under the pipe in the living area.

Originally, solid powder coating companies did not need a sewage outlet, because there was no waste water coming out at all, but as inspectors, they did not know.

So they searched for an hour and finally gave up.

It is only the sewage discharge of domestic water that is sampled, and the other is the gas collected on the left and right sides of the upwind and downwind of the plant.
