The interview was quite smooth.

Zhang Xiaofan talked about a lot of things, which can be regarded as popularizing the knowledge of coatings for the people.

Of course, the biggest task was accomplished, which was to instill the concept of food-grade coatings in people.

Of course, Zhang Xiaofan's ultimate goal is to promote this product.

When most of the people in Yuezhou knew that food-grade paint was a good thing.

When they are shopping for products.

For example, Zhang Xiaofan mentioned air conditioners, guardrail shelves, refrigerators, electric fans, and a series of products that people can easily access.

When they buy these products, they will pay attention to whether the coating on it is a food-grade coating.

In this way, as long as 1 to 2 months, Zhang Xiaofan continues to push to the masses through various ways of media, and Zhimei new materials and food-grade coatings are a reciprocal relationship.

This is what Zhang Xiaofan needs to achieve.

The promotion of food-grade coatings is a means, and it is the final result or to achieve the famous new material of Zhimei.

So Zhang Xiaofan is already preparing to advertise on TV stations.

This time, the target is Yuezhou.

In other places, Zhang Xiaofan's hand couldn't reach it at all, so he could only give up first.

And Zhang Xiaofan really wants to get a title of Yuezhou famous and high-quality products.

Or it is a product exempted from inspection in Yuezhou, and a famous brand product in Yuezhou.

With these titles, then Zhimei New Materials is really famous.

In the past, solid powder coatings were all hidden behind the scenes.

Even ten years later, that's true.

Few people will know which factory company produces the coating and the solid powder coating on the products they use.

What Zhang Xiaofan has to do is to put the solid powder coating companies hidden behind the scenes in front of the stage.

So far, Zhang Xiaofan has not seen any solid powder coating industry that has been advertised on TV.

Maybe there may be some in the print media, but who pays attention to these things, very little.

After the interview, Zhang Xiaofan called Qin Wei'an.

"What? Is the interview over?"

"Thanks!"

"Heh! This has nothing to do with me, if you want to thank you, you can go to thank Zhang, he should have pushed this matter behind. ”

"I don't have his phone, so I can't take the initiative to come to the door so straight!

Why don't you call me?"

Zhang Xiaofan really wants his phone number, and it can be seen from the last time that Zhang Yunlong's status will definitely not be too low.

"Come on, you, just do your good product, just the status of others, do you care if you feel grateful!"

"How can I say that I am also a ...... in the paint industry"

Before Zhang Xiaofan finished speaking, Qin Wei'an directly interrupted.

"Let's expand your company tenfold, this time because you have a good product, but you have to know that the product is something that others can imitate. ”

Or Zhang Xiaofan, who was on the phone, immediately felt a coolness in his vest.

The concept of food-grade coatings has been put forward in China, but not many people care.

This time, Zhang Xiaofan seized this opportunity to spread the concept of food-grade coatings.

But how much benefit can Zhang Xiaofan get from it?

This point depends on how big the gold content of Zhang Xiaofan's products will be?

Qin Wei'an didn't understand this, but Zhang Xiaofan understood it clearly.

Food-grade coatings do not have much technical content, as long as you do the product carefully, the purchase of raw materials is strictly controlled.

It's actually very simple to make food-grade coatings.

Many manufacturers can make it, except for paint manufacturers, of course, because if you are an oil-based coating, you can't say that it is a food-grade paint with a volatile solvent.

However, there are so many manufacturers of solid powder coatings, so that they can study food-grade coatings, although not all of them will be, but some relatively large manufacturers are still easy to come out.

There is no very cutting-edge technology for solid powder coating, that is, when selecting raw materials, choose some raw materials that are free of heavy metals, carcinogenic organic compounds, and harmless to the human body.

Then control the temperature and by-products during production, which is basically easier to study.

So Zhang Xiaofan decided to increase the progress of the research.

At present, the food-grade coatings that are being developed can basically only be used indoors.

Because of the filler.

In general, fillers are used in solid powder coatings.

Fillers have two functions, the first is to increase the rigidity of the coating.

The second is to reduce costs.

The filler used in food-grade coatings is called calcium carbonate.

This kind of thing is everywhere, and to put it bluntly, it's actually a stone.

However, calcium carbonate has many disadvantages, such as its fluidity is very poor, so it causes the flat coating to have poor leveling and low gloss.

The second is that it is very poor weather resistant.

We all know that stone has a weathering effect in geography.

The whole process of forming loose deposits on the surface of the ground or near the surface of the hard rock due to the contact process of the sun and rain atmosphere.

The calcium carbonate applied to the paint is still essentially a rock.

So they have this phenomenon.

Paints made of calcium carbonate as filler are easily weathered by rain after being exposed to the sun.

This results in smearing, which is very easy to peel off and chalify.

Therefore, the food-grade coatings produced by Zhimei New Materials cannot be used outdoors.

It can only be used indoors, and the life span of indoor use is still relatively short.

So the next goal for Zhang Xiaofan.

Very simple.

Research out ...... , uh, no, find a filler that can replace calcium carbonate without weathering.

This is not an easy task.

At present, the mainstream fillers in the coating industry are only calcium carbonate and barium sulfate.

The advantages and disadvantages of each of these are more obvious.

In the case of barium sulfate, in fact, in addition to food-grade coatings, others can generally be used.

When applied to paints, he can actually be regarded as non-toxic.

But the free barium in barium sulfate is actually a heavy metal, so Zhang Xiaofan's method.

Actually, there are two.

The first is to reduce the free amount in barium sulfate as much as possible to a safe threshold.

Or look for a filler that can replace calcium carbonate without the threat of heavy metal content.

Zhang Xiaofan prefers the first option.

However, reducing the free barium content, Zhang Xiaofan is not good at this kind of thing, and even said that he just understands.

These things need to be handled by professionals.

So Zhang Xiaofan decided to support a filler company.

Filler companies generally have a relatively low market capitalization, so they don't need to spend any money, the most important thing is to hire a technician who is very experienced in this area.

That's the key.
