For a long time, Zhang Xiaofan didn't speak, just stared at Liu Qi.

Liu Qi was the first technician he recruited, and he is still relatively satisfied with it.

Maybe as the chief technical engineer of a branch, the qualifications are not very sufficient.

Thinking at a young age can seem more rigid.

Looking at Liu Qicheng's frightened expression, Zhang Xiaofan's heart still softened.

It should still be salvageable.

The best way is to let him get in touch with the different paints and learn more about them.

As long as he knows more and knows more than others, then he will definitely be better than others in terms of innovation.

Sometimes the chief technical engineer of a branch not only wants to be more active in thinking, but also to be a little loyal.

Recently, Liu Qi has performed very well.

So Zhang Xiaofan still decided to cultivate it, but he still had to scold what should be scolded.

"You didn't do anything wrong, it's because I think you have too little to think, maybe my recipe is limiting your thinking, but I want you to forget about it.

Use your imagination well, young people, don't be old-fashioned, experiment with everything, and be a little bolder.

It doesn't matter if you're wrong, I'll take it for you in the back.

But I'm afraid you won't dare to do it!"

Liu Qi lowered his head, his face was very red.

"Mr. Zhang, I'm sorry to live up to your expectations. ”

Zhang Xiaofan's face immediately fell.

"You didn't live up to my expectations, you restrained yourself.

I told you about a recipe for paint, but it's divided into four parts.

You can move the film-forming substance, and you can move the rest.

Like this high-gloss barium sulfate, you can completely replace it with precipitated barium sulfate, so that the color will be a little whiter? Titanium dioxide can be completely replaced by DuPont's, they have the whitest titanium dioxide in the world.

Why don't you add ultramarines to the pigment all the time?

Is it because none of my formulas have ultramarines?

Did you know that ultramarines cover the color yellow very well, and ultramarines are blue-violet and just cancel each other out with yellow.

Although the overall color will be a little blacker, you can add extra ultramarine to make the overall color more blue-violet.

Does this color look much whiter?

You must not think about it from your own point of view, I know that you think that after adding these pigments, the whole color will be black.

But we are professionals, what about those who are not professionals?

They don't have that much color knowledge, they just know what looks white and what looks black.

Do you understand what I mean?

It's how it looks!"

We all know that there are three primary colors of color.

Blue, yellow, red.

These are the three primary colors of color.

These three colors form exactly an equilateral triangle.

In the field of color, it is known as the Iron Triangle of Color.

The three colors are in opposition to each other.

If it's authentic red, blue, yellow.

Red and blue are mixed together, and turning purple can offset yellow.

Red and yellow are mixed together and turning orange can offset blue.

Blue and yellow are mixed together and turning green can counteract red.

When the three pigments of red, blue and yellow are the same, they will become black completely.

This is the relationship between the iron triangle of colors.

Of course, the various pigments we see on the market are not authentic red, orange, red, green, blue, and purple.

Therefore, in terms of practical application, it is necessary to achieve the desired color through the experience and knowledge of technicians and continuous experiments.

That's why Zhang Xiaofan asked Liu Qi to join ultramarine, a color that offsets yellow.

Because of the first generation of fluorescent paint, its color is yellowish.

So it looks very old, when you add ultramarine, a pigment.

It will make the overall color look very white, and it will have a new feeling.

But how did Liu Qi do it?

He has been experimenting with different fluorescent materials and producing finished paints in different colors.

These different paints will have different sheens at night.

During the day, it looks like the color is not much different from the light he can emit at night.

Zhang Xiaofan didn't ask for this.

Zhang Xiaofan's request is that even if this color looks red during the day, I want him to glow yellow at night.

Because today's enterprises are becoming more and more picky, and the requirements are becoming more and more complicated.

Therefore, Zhang Xiaofan only thinks that we must do the corresponding work before they ask for it, and when the time comes, we can only have whatever color we want, and we can fluoresce whatever fluorescent light we want.

"I'm going to arrange it right now, I'm going to experiment right away. ”

Zhang Xiaofan still appreciates this attitude, which is also the attitude that a scientific researcher should have.

As soon as you think of an idea, you can do it right away.

If you stay in the stage of thinking forever and don't do it, you can't make anything.

This is especially true for paints.

Anyway, it only takes about half an hour to make a sample.

What if I was wasting that half an hour?

Make a model, no matter what, you will be rewarded!

"Go ahead, go ahead, use your brains, and don't limit yourself to the circle of recipes.

Think about it from someone else's point of view.

Although you are a technician, I hope that the principle of things is that you stand from the perspective of a technician, but for other external things, you have to stand from the perspective of consumers. ”

Liu Qi nodded gratefully, she knew that Zhang Xiaofan was teaching him how to make a good technique.

"Then I'll arrange it right away, and then what materials should be included? I'll make a bill with the purchasing department when the time comes. ”

Zhang Xiaofan nodded, although the company has a purchasing department, but in fact, the director of the company's procurement department is himself.

It's not time to let go completely, after all, the purchasing department is too easy to degenerate.

And now I am also a part-time worker, and I have to be the chief engineer of the technical department.

These two parts are the most perishable, because many raw material suppliers have to supply goods to the company, and the people they are looking for are usually the purchasing department and the technical chief engineer.

In the case of the same quality and price, how can it be done in.

Naturally, it is to give rebates, rebates to technicians, and rebates to the purchasing department.

Now most of the domestic salesmen feel that giving rebates is a very direct, rough and simple marketing method.

Zhang Xiaofan can't avoid it here.

Because many people have told him about this before, but the materials used by Zhang Xiaofan are all specified, and he must use this company, no kickbacks, but you have to give me a drop in the price.

This matter will definitely not be avoided in the future, and what Zhang Xiaofan can do is to supervise as much as possible.

Anyway, which company is the raw material purchased, Zhang Xiaofan has regulations.

This minimizes corruption in the technical department and procurement.

Zhang Xiaofan doesn't want to change the chief engineer of the technical department or the head of the purchasing department often.

This doesn't do much good for the company.

And the way to reduce corruption is to increase wages and benefits as much as possible.

That Zhang Xiaofan also knew that people's greed was difficult to control, and even some strong-willed people were easily corrupted by this kind of thing.

Therefore, the necessary supervision department must be established.

When the branch is opened in the future, various departments will definitely open it together with his branch.

Ask for a little referral vote.
