Now, of course, it's just a matter of negotiation.

If they saw Zhang Xiaofan's data, it was estimated that they would be scolding immediately, but Zhang Xiaofan was also ready for them to regret it.

After all, even if you sign a contract, you may regret it, let alone just negotiate it now.

Then it doesn't matter, when the data is collected, Zhang Xiaofan can unite one or two companies and get stuck at this level.

The test data must be based only on the test data of an authoritative third-party testing agency.

However, generally large companies will have such test data.

"But I would like to remind you that the oiliness data is just about food-grade paints, not only the content of heavy metals and carcinogenic chemicals.

We must have a responsibility, a responsibility for the cause of environmental protection, and a responsibility for the global atmosphere.

Water-based coatings will definitely have this kind of product, and when Minister Zhang chatted with me, he also made it clear that oil-based coatings should be excluded. ”

Zhang Xiaofan's words made many people very dissatisfied, water-based coatings are still in the development stage, and have not developed to a mature stage.

Each company has its own water-based coatings, but in terms of quality, it does not meet the standards of oil-based coatings, and some companies are still in the research and development stage and do not produce in large quantities.

But Zhang Xiaofan's statement is equivalent to making them give up most of their profits, because water-based coatings are not yet the mainstream.

"This is absolutely not going to work!"

Li Hao quickly stood up and said to Zhang Xiaofan categorically.

If they say yes now, it's like cutting off their arms.

"Oil-based coatings are still the mainstream coatings on the market, and the water-based coatings are not mature enough to be applied to the market on a large scale.

Now recycling technology, the development of more and more perfect, as long as the recycling system is built according to our design, it is difficult to cause great pollution to the atmosphere, after baking oil-based paint, is fully in line with this standard.

Cured oil-based paints have very low levels of heavy metals and organic carcinogens, and many of them even meet EU standards, so I think oil-based paints should not be excluded. ”

Zhang Xiaofan naturally knows that oil-based coatings cannot be ruled out, and eight of the ten companies are mainly oil-based paint companies.

If oil-based paints are excluded, it is conceivable that the consequences must be very serious.

"I'm afraid I can't make the decision on this, but you can make a few copies of your company's test data first, and everyone will discuss it first.

If the company has water-based coatings, it is naturally better, although the current water-based coatings are still in the research and development stage, but I think companies must also have finished products.

At least you have to get a copy of the data, if there is no water-based coating company.

Those oil-based paints with a strong smell, you don't need to take the data, now there is not an oil-based paint with a clean odor, at least this level, otherwise, I don't even need to say it now. ”

The biggest pollution caused by oil-based paint to the environment is its volatiles, which are an organic solvent that will escape into the atmosphere with the coating of paint, causing pollution to the atmosphere.

Paint thinners can be roughly divided into five main categories.

Hydrocarbon solvents, ester solvents, ketone solvents, alcohol solvents, alcohol ether solvents.

No matter what kind of it is, it is very harmful to the human body.

When it comes to odorless paint, he still needs solvents, so he can't really say it's non-toxic.

And now, although this technology is only mastered by a few super-large paint companies, most of them are in Japan.

It was only in 98 years that the concept of deodorization was proposed and applied in practice.

This involves photocatalyst technology, which mainly talks about the decomposition of some odorous, toxic, and odorous chemicals into water or carbon dioxide, or nitric oxide through photocatalyst action, so as to achieve the purpose of deodorization.

However, this photocatalyst must have a premise, that is, it must be exposed to ultraviolet rays.

To put it bluntly, there must be an ultraviolet light source, and sunlight is also possible.

said to Zhang Xiaofan.

They didn't have the courage to ask Zhang Yinlong, so there was no way so far, and now they could only be handled by Zhang Xiaofan.

Since Zhang Xiaofan said that he would talk about other things after looking at the test data.

Then I have to take out and make a few copies of my own test data.

"Wait a minute, I'll find someone to help. ”

Zhang Xiaofan is looking for someone, naturally looking for a person who is very good at excel technology.

This kind of person is fairly easy to find in the government department.

What Zhang Xiaofan wants to do is to input all the testing data of each company into the computer.

Each item is then divided into rows, and comparisons are made on each line.

Who's the best.

In fact, in other words, who has the lowest content of heavy metals and carcinogenic organic compounds.

Whoever is better will be better.

This is not done for a purpose, and it will definitely leave them dumbfounded.

However, it takes time to enter data, and Zhang Xiaofan can afford to wait, but the other nine companies, because they don't know what Zhang Xiaofan is going to do, are full of impatience on their faces.

Anyway, there is always a bad feeling, especially when I look at Zhang Xiaofan's expression of an old god.

Then the typer next to him crackled on the keyboard without distraction.

The office is unusually quiet, in fact, there is no need to call someone to come over here to input this kind of thing, just hand over the data to the typist and let him solve it, but Zhang Xiaofan just called over.

Most people are afraid of the unknown.

Before Zhang Xiaofan said it, they could only rely on guessing.

Maybe this data is typed out for the people above, and it may be a basis for Zhang Xiaofan to persuade the people above.

Anyway, they really didn't know what Zhang Xiaofan's plans were.

After nearly 40 minutes, the data entry was finally completed.

"Wait a minute, now each row is an item, put these lines, from 1 all the way to 27 items, these 27 lines, each row takes the smallest number, and marks it red.

Lines 27 to 30, whichever is the highest.

Line 31 takes the smallest number.

……

Then all in red. ”

Zhang Xiaofan said as he operated.

Then print out all the pages. ”

On the computer, the shock is completely invisible.

Once these papers are printed, it is too obvious, everyone is a technician, and they know that what Zhang Xiaofan said about red is that in this project, the manufacturer of red is the best.

Now it's clear that when you look at it completely, almost all of them are marked red.

Almost everyone looked at Zhang Xiaofan in disbelief.

Except for one project, Zhimei New Materials did not get the red, and all the other projects were the best.

How is this possible!
