On weekends, Zhang Xiaofan arranges a rest for himself.

Although for the solid powder coating industry, weekends are a luxury, but Zhang Xiaofan is also the boss, and occasionally there are important things, he will still rush to the company.

In fact, for many small company technicians, weekends are often impossible, especially in the solid powder coating industry, this kind of order-based production.

What's more, if there is an order, then start work, and if there is no order, you can rest on Monday or Saturday.

Of course, if the company grows bigger, this is easier to arrange, anyway, there are so many technicians, everyone takes turns to rest.

Zhang Xiaofan is not an exploiter, and he does not want to be an exploiter, so any employee in Zhimei New Materials has two days off a week and is paid for overtime.

Zhang Xiaofan always believes that any mental agitation is not as good as the actual interests of the impress, to improve the efficiency of the company, they must have enough interests and enough rest.

So on Saturday morning, Zhang Xiaofan likes to lie in bed.

Even if he is the only one in the bed and has no other body to accompany him, he likes to lie in bed.

And then there is always a group of people who like to disturb your dreams.

Zhang Xiaofan was woken up by the ringing of the phone on Saturday morning.

Zhang Xiaofan didn't care who was calling, his right hand pressed directly to answer the phone according to inertia.

"If you don't give me a reasonable explanation today, I'll wake you up on time at 6 o'clock every morning. ”

"Mr. Zhang......"

The voice was a little hoarse, and Zhang Xiaofan couldn't tell who it was.

"I'm waiting for your explanation. ”

"We succeeded......"

Although his voice was still hoarse, the irrepressible excitement could still be clearly expressed through the phone, so that Zhang Xiaofan could hear it.

"And then ......"

The other party still didn't report his home, Zhang Xiaofan couldn't help but glance at the phone screen and found that it was Zhou Yixin.

They succeeded, which means that the wood grain transfer paper has been printed.

This is indeed good news.

"Mr. Zhou, I'm so embarrassed, I thought it was a joke for me to be a bad friend!"

"It's okay, it's okay", Zhou Yixin smiled wryly, at this time, he couldn't help but pay attention to the time, and found that it was less than six o'clock.

Last night, there was a sudden breakthrough in the drawing of wood grain transfer paper, so he rushed out a little overnight.

I just completed a trial production in the morning, and then I couldn't wait to call Zhang Xiaofan, just to give Zhang Xiaofan good news.

He knew that Zhang Xiaofan was in a hurry, so he didn't pay attention to the time.

"I'll come over later, you guys get ready. ”

Zhang Xiaofan was a carp, quickly dressed, washed, and had breakfast, and rushed directly to them.

After seeing the sample, Zhang Xiaofan was impatient and returned to the company with the sample.

Wood grain transfer, the final color is actually difficult to predict.

After the ink passes through high temperature, there will be a variety of changes, and this change will be slightly different according to the different environment, different temperatures, and different times.

So we have to experiment, we have to keep experimenting.

Do about ten experiments in a row, with different temperatures, different times.

Then summarize which time period and which time period is more stable!

Then the temperature range and the length of time can be used as reference data for manufacturers.

This data will vary according to the different primer coatings and the different colors of the wood grain transfer paper.

The process of wood grain transfer printing is actually divided into two steps.

The first step is to spray primer paint, which is actually no different from ordinary paint, but the curing temperature and time are higher and longer than ordinary paint.

The second step is heat transfer.

Taking the door and window industry as an example, before the doors and windows are formed, they are all aluminum profiles about six meters long.

The wood grain transfer paper, the side of the pattern is aligned with the profile and wraps it.

Then put a layer of high-temperature resistant plastic bag on the outside, and then vacuum, the purpose is to make the transfer paper can be very tightly attached to the aluminum profile.

Finally, it is baked at a high temperature to transfer the pattern on the transfer paper to the aluminum profile.

This temperature control is very important, if the temperature is too high, then the ink sublimation is too much, and the pattern will be very blurry.

When the temperature is a little lower, all the ink adheres to the surface, and the pattern disappears after a little longer use, but if the temperature is too low, the transferred lines will be intermittent.

For several technicians who have mastered the transfer technology, the experimental transfer temperature range is actually very familiar.

By the afternoon, they had already produced the full report.

The next day, Zhang Xiaofan took the sample made by the experiment and came to Incheon doors and windows with Deng Xiaoni.

"Zhang Gong, can you guarantee that the effect we make is the same!"

Of course, after Mr. Wang of the Incheon doors and windows looked at it, he couldn't put it down, and this sample was a little farther away, about a meter away, and it looked like a piece of wood.

The feel on it is also very close to wood.

This made him very impressed by the technical level of this enterprise, but he didn't know if his workers could make such a level.

"There will definitely be a little difference, this thing is indisputable, even if we are the same person, the same standard, there will be a slight difference in making it twice. ”

Mr. Wang nodded, there are no two leaves in the world that are exactly the same, and he naturally knows that the paint is actually very complicated when it is formed.

"How big is the difference?"

"If you follow the criteria we give, it won't be more than 10%. ”

In fact, Zhang Xiaofan doesn't want to use 10% of this data, but the color change of the finished wood grain transfer product is actually very unstable.

He has to judge according to the quality of the transfer paper, but the transfer paper is often an unstable factor.

Therefore, Zhang Xiaofan could not give an accurate answer, and the most important point is that the color of the wood grain is very complex and cannot be judged with a colorimeter.

So I had to use the percentage data.

At this time, Mr. Wang's brows furrowed, and he felt that the color difference of 10% was a bit big.

That was Zhang Xiaofan then added.

"In fact, if we look directly at it, it is difficult to observe the difference. ”

Mr. Wang on the other side was stunned for a moment, the difference of 10%, can't the vision be judged.

Zhang Xiaofan took out a few more samples.

"Mr. Wang, take a look, can you feel the difference between them?"

The difference must be there, and it is obvious, but in Mr. Wang's subconscious, he feels that these things are on the same wood.

"Why do I feel a big difference, but ......?"
