The human body must not inhale too much dust, which will have a great impact on the internal environment of the human body, although we will inhale dust when we breathe every day.

That's because our human body structure is very delicate, there are nose hairs that can block part of it, mouth and throat mucus can also block part of it, and we also have tiny cilia in our throat, which can also block part of it.

However, there will always be some dust entering the lungs, and these things are actually difficult to photograph, especially those with a particle size of less than 2.5 microns, which are basically difficult to expel them.

This dust is also the main culprit of inflammation in the lungs and throat, why do many people have laryngitis repeatedly? It is because the living environment is not good enough, so we often do nasal cleaning, which is beneficial.

Some details of powder coating are difficult for others to notice, and any powder coating product of Zhimei New Materials, with a particle size of less than 2.5 microns, is almost none, and even less than 5 microns has a very small powder particle content.

This is very strict about the size distribution of the product, which may feel very easy to spray when used and not prone to some dust, but they don't think about it deeply.

Zhang Xiaofan makes such a product, it must be for the health of the workers who use this product, the finer the particles, the more difficult it is to be blocked by the protective product, so this is why Zhang Xiaofan is very strict in particle size control.

Others use their own products, is a kind of trust in themselves, so some things should be considered for them, many powder coating spraying workers sit for ten years, which makes them accumulate a large number of powder particles in their lungs, which is a very big hidden danger to health, so to avoid this situation as much as possible, that is, in the powder particle size distribution, to control very strictly.

In this way, particles less than five microns will be very few, or even close to zero, so that these examples can be excreted by the oral mucosa, nose hair, and cilia.

If you add protective gear, you can inhale very, very little dust into your lungs, even less than walking on a country road.

Chen Ying handled the incident very quickly, and then the compensation was also processed very quickly, and it was processed in less than a week.

Those spray guns that did not have problems were also recalled, but these would have to pay very little compensation, or even only the purchase price of the machinery.

Zhang Xiaofan came to the capital the next day, and Professor Qin's laboratory did not stop experimenting, and he was constantly looking for a solution.

"I'm sorry! I was a little excited last time. ”

Zhang Xiaofan's first sentence when he met was to apologize, because the biggest responsibility for this matter still lies with Zhang Xiaofan himself, because these products were agreed to be mass-produced and sold after Zhang Xiaofan's testing was completed.

If you don't think about completely putting the blame on others, you are always suspected of shirking your responsibility.

"I now have two solutions, the first is to enhance the tightness of the machinery, and the second is to completely overturn the previous solution and redesign. ”

Professor Please seemed to be a little deaf to Zhang Xiaofan's apology, but his face changed slightly, and then he didn't say anything, and directly said his own plan.

"Sealing equipment, after all, is a symptom rather than a cure, maybe there will be no problems in a year or two, but the machine will be used for a long time will have many problems, which is harmful to our company's reputation, I do not approve of this plan.

I think we should still redesign, and my idea is to use as rough a design solution as possible, because in the future we will be dealing with more than just skilled workers.

It will be more for the general public without any technical means, so I think our products should be easier to use, can adapt to all kinds of harsh environments, whether it is high temperature, low temperature, humidity, or a lot of dust.

In such an environment, the normal operation of the machinery should be ensured, and we should reduce the probability of mechanical equipment problems as much as possible, so my idea is actually.

For extensive devices, especially its control panel, we need to reduce the buttons, reduce the knobs, preferably just a switch on, and then you can use it.

The equipment does not need to be sealed, or even one or two screws can be disassembled, and then they can simply repair the equipment that has problems. ”

In today's increasingly close mechanical and electronic equipment, Zhang Xiaofan's ideas are indeed somewhat different.

However, Professor Qin thinks that this idea is very good, rough equipment does not mean that the performance will be lower than that of precision equipment, but only that such equipment can be used as usual in harsh environments, and will not make the equipment suddenly strike.

Devices that can adapt to a variety of environments, or devices that can be easily operated by ordinary people, but although their functions may not be very comprehensive, they are much ahead of other devices in terms of certain functions.

"I've been to a few spraying factories in the past few days, and the environment there is really worrying, I don't know if these workers will be able to withstand it in a few months or years?"

"If they use our products, the problem is relatively simple, our products have very few particle sizes below five microns, so as long as they wear protective products, there is basically no such risk. ”

"Really?"

For Zhang Xiaofan's statement, Professor Qin has some doubts, she has been to the spraying factory, since the products are powder coatings, then there must be some general characteristics of powder coatings, such as the dust flying in the sky, in the workshop are extremely blurred.

"This is naturally true, we have particle size detectors, these can be detected by instruments, I don't have to lie.

Professor Qin can go to our company, you are willing to pick one, we have it in stock, or it has just been produced, you can personally check the particle size, you can know if I am lying. ”

"You've done a great job of that. ”

Since Zhang Xiaofan said so, the possibility of Zhang Xiaofan lying is relatively low, but Professor Qin, who is more serious, is really ready to go, because she wants to determine how meaningful what she is doing now will be?

"Basic operation. ”

However, Zhang Xiaofan regretted it as soon as he finished speaking, and he didn't know whether Professor Qin understood the meaning of these four words.

"Okay, I'll consider your ideas carefully, and I'll give you a complete plan in a few days.

I'm going to do experiments, you go ahead and get busy with yours. "You have to find the latest chapters by yourself when you read books?
