Shenjiang University.

School of Chemistry and Chemical Engineering.

Inside a standard laboratory.

Professor Wu looked at the table in front of him with great excitement.

There are rows of molecular formulas, chemical names and contents.

"Good job. ”

Professor Wu patted Chen Dong on the shoulder very kindly.

I didn't go back at all during the Chinese New Year, and I have been doing experiments, analyzing various data, and doing various spectra.

Until today, all the analysis and testing have finally been completed, looking at the molecular formulas one by one.

Professor Wu pondered in his heart what kind of material these things were.

Take out a piece of paper and start the elimination method.

Paints are such things, and raw materials must be distinguished.

It can be divided into four main categories.

First, film-forming substances.

The film-forming substance is mainly composed of two components, the first is the resin, and the second is the curing agent.

These two things react when exposed to high temperatures or ultraviolet rays to solidify into inert organic matter, which can adhere to the surface of metal or other things to form a common protective layer to protect the substrate from corrosion.

Resin is one of the most important raw materials for coatings, which can be epoxy resin or polyester resin.

These are synthesized by organic matter.

Second, fillers.

This is easy to understand, in fact, it is a powder ground from ore, which is added to the coating to increase the rigidity of the coating and reduce the cost.

This amount must be appropriate, add less, the cost will be very high, but if you add more, the quality of the paint will also drop a lot.

Third, pigments.

That is, red, orange, yellow, green, blue, purple, black and white.

Fourth, additives.

Additives are not used in many coatings, but they are very important.

For example, we commonly see a flat highlight, matte surface, or orange vein.

These are to be achieved through additives, additives can make our coatings more beautiful and beautiful, or look very beautiful patterns, or increase the service life of the coating, and so on.

What Professor Wu is doing now is to slowly turn these molecular formulas into various raw materials through his own transformation.

This is an epoxy resin with a content of 30.7%.

This resin containing hydroxyl group should react with epoxy with a content of 29.3%.

……

This should be a leveling agent.

This is benzoin.

……

What is this?

Vitamin C?

And vitamin A?

This afternoon I was completely confused, is it useful to add these vitamins?

Does this have any special implications?

The front one is okay to say.

are some very commonly used things, what epoxy resins, polyester resins, additives, pigments.

These are relatively easy to understand, in fact, many minor ingredients can be completely ignored.

Because the raw materials used by each manufacturer are different, many of his small ingredients will also make great differences.

But no matter how small the ingredients are, there will not be a vitamin series in them.

Could it be that this product is so delicate because of the addition of vitamins?

Professor Wu put this question out of his mind for the time being.

Now he's more entangled.

The resin generally used by domestic manufacturers either contains a carboxyl group alone or a hydroxyl group alone.

But there is a polyester resin in it, which contains both hydroxyl and carboxyl groups.

In fact, few manufacturers will apply this kind of resin, he is very unstable, people who have studied chemistry know that the hydroxyl group and the carboxyl group will react by themselves.

The same product contains both carboxyl and hydroxyl groups, which react on their own if the conditions are right.

But the most beautiful one is used.

Either there are two possibilities.

The first is the technician, who is very confident in his own technology, and he can perfectly control the proportion of the reaction of each ingredient, starting with my bold addition of this product with low stability.

There is also a possibility that this is a raw material that is not purchased by the manufacturer, and the polyester resin itself contains this unstable component.

Which one is it?

Now Professor Wu is very entangled in whether to add this thing or not.

If this thing is added, in case the balance of the formula of one's own anti-reasoning is not reached, then there will be an unpredictable reaction.

And most importantly, the temperature you have is different, and it may produce different results.

This made Professor Wu scratch his ears and cheeks a little.

Another big trouble is that the raw materials purchased by this Zhimei new material are purchased.

I don't know which one it is, and the products they produce will definitely be quite different from different raw material manufacturers.

This may lead to the fact that if the products of different manufacturers are used, even if the formula is completely consistent, the effect of the new material will not be achieved.

Professor Wu has written at least a dozen possible recipes.

And the materials have to be tested one by one, which is simply torturous.

Count it down and ignore some of the tiniest ingredients.

Zhimei New Materials produces at least 48 such coatings.

In the past, the coatings of other manufacturers can be recognized with more than 20 kinds of ingredients.

Professor Wu, now you can be sure.

Zhimei New Material must have added a lot of interfering ingredients to it.

But what puzzled Professor Wu was why this technician was so bold.

Dare to add this kind of thing so easily, isn't he afraid of unpredictable changes in the entire paint?

The most frustrating thing is that he dared to add vitamins.

Right now, I'm very unsure if vitamins will work in the paint, or just interfere with the ingredients.

Zhang Xiaofan's secret interference ingredients on the formula did add a lot of trouble to Professor Wu.

The further back he wrote, the more irritated Professor Wu became.

Originally, I thought that various molecular formulas came out, but I only had to reason backwards to know which material and which material it was.

But now Professor Wu has completely abandoned this idea.

He felt that the person who designed the recipe was too fucked up, how many experiments it had to be done, how many interfering ingredients to be eliminated.

However, when he thought of the profits generated by this paint, Professor Wu's heart was itching, and now he is coming to the ceiling, and the monthly consumption is nearly 100 tons.

I am very sure that the cost of this formula is relatively low, and it is even lower than the current Weishi Paint any ordinary coating.

That is, the profit of one ton is definitely above 12000.

The profit is nearly 1.2 million a month, and according to the sharing ratio, I will say that I can get at least 350,000.

With such a big profit, Professor Wu is reluctant to give up.

You know, there will be more and more ceiling manufacturers, will find the most beautiful new materials, this kind of high-quality coatings.

As a result, the output of Weishi will be further reduced, and Professor Wu's share will be even lower.

Comparing the two, I just feel that I must speed up the pace of realization and call the people of Weishi over.

More people have great strength, eliminate some interfering ingredients as soon as possible, and then restore the true color of the paint.
