After Deng Xiaoni went out, Zhang Xiaofan was in a daze with the sales report, to be honest, the calmness he showed just now was actually for the sake of reassuring people's hearts, but when he carefully studied the report, he also fell into confusion.

Is it really wrong?

Who is wrong? Is it yourself, Professor Qin, or Deng Xiaoni, or is it the consumer?

Suddenly I feel a little stunned, the things that have been decided are better not to think nonsense, no matter what, the electrostatic spray gun is definitely a very important part of the entire coating chemical industry, Zhang Xiaofan can not give up.

Since you don't give up, then you can only move forward bravely.

If he is not familiar with precision instruments, he can only work the coating, and Zhang Xiaofan, who was a little lazy, decided to return to the capital and keep an eye on the laboratory.

At present, the company does not need to spend too much energy, because the company's technical strength is already the top in the country, so there is no need to consider the company's production technology, and now the main focus is on the new powder coating that can adapt to the new electrostatic spray gun in the future.

The sales of products are always linked, take the building materials business as an example, do cement, often come with the sale of sand pebbles, there is capital may also consider doing steel bars, and even with some small hardware such as switch appliances, some may also do floor paint, or other self-leveling materials.

Because the use of these things is associated with the effect, sand and cement pebbles, if it is a small batch, others will not buy in different places, and the same is true for hardware.

If the electrostatic spray gun has an excellent effect, the powder coating will also have a driving effect, and the quality of the powder coating has an electrostatic spray gun, which will naturally have a driving effect, but if there is a problem on either side, it will definitely affect the other party.

Just like now there is a problem with the electrostatic spray gun of Zhimei New Materials, so the sales of powder coating have also declined, Zhang Xiaofan only understands it as a decline, but Deng Xiaoni thinks that this is a fault.

The speed of messaging in an industry is always beyond your imagination.

Intentional and unintentional, coupled with the help of some people, always make some people who don't want to be famous become famous quickly, whether you have a good reputation or a bad reputation.

However, these things are now all handled by Chen Ying and Deng Xiaoni, and Zhang Xiaofan feels that the most important thing he should do now is to cooperate with Professor Qin to develop a product that makes others shut up, which is what needs to be done urgently.

And Zhang Xiaofan is also doing it now, but she is doing this, she joined the ranks of research and development, and is doing experiments in person, which actually makes many technicians who accompany her very sideways, Zhang Xiaofan is now worth billions of dollars, but no one has ever seen billions of bosses and personally do experiments.

There will never be a shortage of curious people in the world, and some people think that Zhang Xiaofan is making a show, and it is estimated that he will not be able to last for half a day, because everyone who has done experiments knows that this process is very, boring and repeating the experiment over and over again.

I think many undergraduates who have come out of chemistry majors have a relatively intuitive understanding that you have to keep an eye on an experiment for three hours or four hours, in case something happens to him in the middle, not to mention repeating these experiments ten or twenty times, one hundred times and two hundred times, this kind of thing can no longer be simply described as boring.

Professor Qin, who came to the laboratory, glanced at Zhang Xiaofan's position in surprise, and then stared at it carefully, only to really confirm that it was Zhang Xiaofan who was doing the experiment.

She came here today to have a good exchange of her thoughts with the person in charge here.

Professor Qin suddenly subconsciously glanced out the window to see if the sun was in the wrong direction today, she had also criticized Zhang Xiaofan before, and felt that as an experimenter, she should not lose her skills.

But every time Zhang Xiaofan nodded in agreement, and then, after she turned her head, she disappeared, anyway, there were various reasons.

After one or two times, she didn't bother to say something annoying, after all, she was not Zhang Xiaofan's anyone.

"Mr. Zhang, since you are here, then I don't have to worry about the two masters, one of my students put forward an idea, and the theory is to support the birth of a new type of equipment.

But I don't know if your product can meet the standard of use of this conjecture. ”

"Tell me about it first, and if not, we'll find a way to get him up to that standard. ”

Please the professor nodded, this is the attitude that a R&D person should have, I will go on it, if it doesn't work, I will find a way to let him go.

"Can your powder coatings be mixed with water to form a brief suspension?"

Professor Qin knew that what Zhang Xiaofan was doing now was how to be closer to environmental protection, so she did not mention other solvents, but chose water as the solvent.

"You mean your students came up with the idea of spraying powder coatings in a similar way to spraying paint?"

It is certainly not wrong to understand this way, the spraying of paint requires a large number of thinners, that is, the various aromatic groups we usually see - similar to benzene, toluene, xylene and the like, as well as ether ketones, the common feature of these substances is volatile, and very harmful to the human body.

Most of the smell of paint is also caused by these thinners, especially pay attention to the original thinners, benzene, toluene, xylene and the like, which are quite harmful to the human body, and very high carcinogenicity.

The use of water as a diluent proposed by Professor Qin to dilute powder coatings and water-based coatings, and using water as a solvent are completely different things.

The most important function of powder coating dilution with water is to make it flow liquid, and water-based coating with water as a diluent, which will add a lot of short-chain volatile organic compounds.

Water-based coatings will still cause great pollution to the atmosphere in the film-forming process, and will also pollute water.

However, if the powder coating is diluted with water and then sprayed, it will not pollute the water and the atmosphere because the powder coating is completely insoluble in water.

"Yes, the liquid state is easier to adhere to the surface of the object, so as to achieve the purpose of spraying. ”

"I can try this method, I will improve the particle size of the powder coating, without adding any other solvents, the powder coating particles can be temporarily suspended in the aqueous solution.

I would like to suggest that you can design a small mechanism so that the gas can pass through the aqueous solution, which can also stir the whole suspension, so that the powder coating suspension is more uniform, so that there will be no color difference when spraying, and there will be no places where only water is sprayed, and no powder coating is sprayed. ”

If you let the gas go to the bottom of the equipment and pass through the entire suspension in the form of small bubbles, you can stir the whole suspension, and the suspension will flow up and down through the left and right, so that the powder coating concentration of the upper and lower layers of the suspension is consistent.

Then the powder coating suspension is sprayed out of the nozzle with the pressure of air pressure and attached to the surface of the object to complete the entire spraying process.

"Your suggestion is very good, and we will refine your idea into the whole system. "You have to find the latest chapters by yourself when you read books?
