A group of technicians listened more carefully, and when they heard that Zhang Xiaofan was going to lead the team, it was obvious that many people were very excited on their faces.

Now that we have entered the coating industry, this industry, and the solid powder coating industry, everyone's pursuit of technology, although the degree is different, but everyone naturally wants to forge ahead.

Everyone knows that Zhang Xiaofan's technical level is very high, so if Zhang Xiaofan leads the team, then the technicians below can learn a lot, who is not excited!

"I won't say much about the transparent coating of the wheel, Liu Qi has done a good job, and most of the technical difficulties have been overcome at present.

Just pay attention to some very small details, and now the focus of your research and development is on how to improve his weather resistance, stone chip resistance.

Another is to control the particle size, which is actually the biggest focus, but you have also done so many coatings, for the control of particle size, you should have your own experience, I will not say more. ”

Liu Qi nodded, if you want to talk about the control of granularity, he does have a lot of experience.

The current particle size control of Zhimei New Materials is definitely at the top in the world in the entire industry, and this credit should belong to Liu Qi.

Don't underestimate this granular control, he says that it is the watershed that separates the truly cutting-edge technology from the average technology.

Particle size distribution, in fact, is a worldwide issue.

The finished products of solid powder coatings are all fine particles with a particle size of about 5 microns to 100 microns.

This particle can fly into the air with a gentle blow.

The optimal particle size for powder coating is about 30 microns.

However, this also depends on the formulation of your paint, and the optimal particle size is about 25 microns to 35 meters.

If you have a product that almost 99% of the particle size is controlled around 30 microns, about 28 microns to 32 microns.

Then your product is absolutely god-level in the world, this product is very easy to spray, and the surface of this product sprayed is either very flat, or the sand will be very uniform.

This is the product standard that basically all solid powder coating manufacturers dream of.

But so far, no manufacturer has been able to reach it.

Zhimei new materials also do not meet this requirement.

So Zhang Xiaofan asked Liu Qi to increase the ratio between 28 microns and 32 microns as much as possible.

The higher this ratio, the better the quality of the product.

This is also the biggest reason why Zhimei new material products can crush the products of other manufacturers in the market at present.

"The primer, as the name suggests, is the filler primer.

This group is headed by Lin Wei. ”

Hearing his name, Lin Wei felt that his heart was about to jump out.

In his impression, such a good thing will definitely not fall on his head, although this team leader may not be the most when he distributes the bonus in the future.

For the bonus reward for R&D, if it is a group, it is not necessarily that the group leader will allocate the most, but the person who contributes the most will receive the most.

Every group discussion will have a very detailed transcript, so who came up with an idea, who came up with an idea, or who suddenly made a major discovery during the experiment?

These will be recorded, and finally several people from the technical department plus Zhang Xiaofan will conduct a value assessment, so that the bonus will be distributed.

Basically all technicians accept this assignment.

But now Lin Wei is still extremely excited, such a heavy responsibility falls on his shoulders, this is Zhang Xiaofan's trust in him, can this make him not excited?

Now basically all the technicians here have higher education than him, but he still won the position of team leader.

"Mr. Zhang, don't worry, I will definitely complete the task. ”

"Do you know how?"

At this time, Lin Wei was suddenly stunned, and he felt some pain on his face, but seriously, he really didn't have any direction.

After all, he has basically never been exposed to this kind of primer, so there is no way to talk about the direction.

In the end, I could only smile awkwardly.

"Wait a minute, I'll go through some information. ”

"When you look through the information, the daylilies are cold.

Make a note of it!"

Because he immediately flipped out his notebook, it was an attitude, and in every meeting, he would record the key content.

Zhang Xiaofan also likes him, a good memory is not as good as a bad pen.

"The biggest role of the primer is to fill the substrate and smooth out the marks on the substrate as much as possible.

Our current project is mainly aimed at automotive wheels, but we know that automotive wheels must be inverted.

Needless to say, the mold must be uneven, although they will be carefully polished, but the surface will still be rough and uneven.

So at this time, the function of this paint is revealed.

Because the most important thing you pay attention to in the primer, and you have to pay attention to, is viscosity.

The second point is the speed of reaction.

We don't know what the specific data is, so we have to rely on the data from your experiments to fill in this gap.

The third point is also quite important, and sometimes even the third point is more important than the first and second points.

The adhesion must be exceptionally good, not only for the adhesion of the aluminum alloy, but also for the adhesion of the coating itself.

As for the substrate, you yourself go to Fangnan Wheel to find their workshop director to ask for it.

They have this alloy substrate and then let their workers polish it, so that they can restore the characteristics of the wheel after it is formed. ”

It is easy to understand why adhesion should be exceptionally good.

The primer, one layer contacts the aluminum alloy and the other layer contacts the coating, so it has the adhesion of the aluminum alloy, which must be good, and the adhesion to the coating itself must also be good.

Regardless of the problem at any point, the entire layer will easily peel off.

So Zhang Xiaofan emphasized these three points.

"I see. ”

This time, Lin Wei will not erect a flagpole, Zhang Xiaofan has already given the direction, given the research points, and then as long as he grasps it himself.

Anyway, the real research and development must rely on the team members, each group has at least one doctor, two masters, seven or eight undergraduates, and the real contribution must be these team members.

Lin Wei is also very clear about this, he doesn't have much luxury for bonuses, after all, the distribution system is already there.

Now that Zhang Xiaofan has given him rights, it is the greatest trust in him.

So although he didn't say it, he was silently cheering himself up in his heart, and he must satisfy Zhang Xiaofan and the company.
