Weishi coatings.

A very simple office with a furnishing.

Li Yang sat on the top.

Then there were two people sitting next to them, probably in their 30s, and three young people sitting on the other side of the table.

"It's this ingredient list, and what we're doing today is to analyze and weed out some ingredients that are completely unnecessary. ”

This time, the formula sent by Professor Wu was completely different from the previous one, and the previous Professor Wu had even basically calibrated which material was which.

But this time, it was just an ingredient list.

The most important thing is that there are nearly 49 kinds of ingredients in it that meet the testing standards, which will be a very big project for Li Yang and them.

Since there are 49 kinds of ingredients in the ingredient list sent by Professor Wu.

In other words, Professor Wu has no way to rule out any of these 49 types.

This actually surprised Li Yang very much, you know, there are some ingredients that Professor Wu can't rule out.

It is entirely conceivable how similar there is, and it can also reflect the depth of the understanding of the technical staff who designed the formulation, the basis of chemistry and the coating.

Li Yang is actually very worried, people who can design such a formula will definitely be able to design other better formulas.

If Weishi Coating, here to exert a lot of manpower and material resources to develop this formula, but if the technician of the new material of the United States suddenly comes up with a new formula, will it take manpower and material resources to study this formula?

But now the boss has given a death order, and for this vast market, the boss does not want to give up.

So Li Yang had no choice but to bite the bullet and call a group of experienced technicians to eliminate some unnecessary ingredients first.

One person counts short, three people count long.

Maybe others don't have many advantages, but there are always one or two shining points, so Li Yang doesn't want to give up any opportunity to reduce manpower and material resources.

"Let's take a look at this ingredient list first, at least half of it is interference, so you have to think about it carefully, see which ingredients you think are impossible, and then explain why. ”

The two older technicians looked serious, after all, Li Yang asked them to analyze that it must be Li Yang, and it was difficult to find out the interference components.

But for the three young technicians, they are more excited, after all, this is an opportunity for their own performance, and it is difficult to have such an opportunity in their work, so now they are thinking about how to seize this opportunity and find out those interferences.

The two older technicians frowned more and more, and there were a lot of two or three very high levels of content, which would add more difficulty to the work of distinguishing.

Seeing the five people below meditating, Li Yang himself was also thinking, he actually watched it all night last night, but he really couldn't find any clues.

That's why I brought it over today for everyone to discuss.

In fact, Li Yang is more optimistic about the three young technicians, after all, their minds are still very active.

It's not at all like I've been in the position of chief engineer for a long time, and what I want is stability and stability.

Then, after a long period of stability, the ability to innovate and the activity of thinking are much worse.

Once a person stays in a comfortable environment for too long and does too many repetitive things, the person's mind and spirit will be lazy, and he will no longer say anything like innovation.

At this time, a young technician stood up, and you remember that his name was Wang Dawei.

"Mr. Li, I don't think this is possible. ”

As he spoke, Wang Dawei spread the ingredient list on the table, and then pointed out an ingredient.

"Tell me, come, let's listen to it and see if it makes sense. ”

Seeing five people coming around, Wang Dawei was actually a little nervous.

However, seeing Li Yang's encouraging eyes, Wang Dawei also mustered up courage.

"Mr. Li once told us that for flat powder, it is best to have as few functional groups as possible, so that his leveling effect can be more prominent.

But if you look at this ingredient, it actually contains both carboxyl and hydroxyl groups, and it actually contains methyl and phenyl groups.

I counted carefully, and there were about 14 functional groups, and there were as many as six functional groups that could participate in the reaction.

Does it affect the flatness of the coating?"

At first, it seemed to make some sense, but Li Yang thought about it carefully, since Professor Wu had handed over this formula to Weishi Coating.

That proves that they have tested it in the laboratory, which means that this ingredient does not affect the flatness of the coating.

So it's basically ruled out, but you can't directly deny this Wang Dawei, which may discourage his self-confidence.

But then Wang Dawei's words made Li Yang suddenly brightened.

"And he shouldn't be involved in the reaction, and if he does, then there will definitely be some flaws in the flatness, and it will be added very little, only 0.3%, which means that it will not participate in the reaction and will not have an impact on the overall performance of the coating. ”

Li Yang didn't pay attention to the ingredient that Wang Dawei had just proposed.

Instead, he suddenly thought of a possibility.

The components of any paint are made up of four components.

Why do we have to rule out the impossible?

Let's pick out all the possibilities first, and then spend time trying to eliminate the impossible.

It's a lot less work.

"Everyone came here, just now I thought of a very important point, we know that the coating has four major components, these two are epoxy resin and polyester resin, which is undoubted, this is barium sulfate, this is titanium dioxide......"

He calls you one sentence at a time, picking out all the necessary ingredients.

"Okay, these 14 kinds, let's not think about them anymore, these main materials.

What we need to do now is to map these main materials to the raw materials of each manufacturer, because the raw material content of each manufacturer will be different.

So what we have to do now, first, is to supply the raw materials that we know to the manufacturers and let them provide the ingredient content list.

Surely the ingredients of each raw material supplier will not be very pure, so he will definitely have some extremely trace ingredients attached to it.

After we get the ingredient list of these manufacturers, let's compare the ingredient list to see which ingredients are attached, which can reduce some of our workload.

Now let's go our separate ways, everybody is responsible for the part, you are responsible for the epoxy part and the polyester part......"

After Li Yang divided the work among everyone, he began to do some work himself, contact Professor Wu, tell him what he thought, and then ask Professor Wu to come over to help, preferably bring all his students over.

Because when it comes to basic chemistry, Professor Wu and his students have a very solid foundation, so they can better analyze what is necessary and what is unnecessary.
