"You look very beautiful with these products, but their shortcomings are also very obvious.

The environment in which the car is usually placed is quite harsh, there will be all kinds of animal feces, dust, sunlight, and acid rain.

These things are actually more obvious for the surface erosion of the coating.

Therefore, when we use materials, we must choose some pigment products with excellent weather resistance and excellent acid and alkali resistance.

To put it bluntly, it is necessary to withstand the sun's rays and the wind and rain. ”

Zhang Xiaofan said so much, Li Boshi was even more puzzled.

Now that you know what to use these pigments, you have solved the problem for now.

Why are there still many technical difficulties?

"But we chose these materials, which are quite different from traditional metallic pigments.

To put it bluntly, metallic pigments are made of metal, such as silver, which is made of aluminum.

The golden bronze ones are all of bronze.

The bonding between the metallic pigment and the primer is relatively easy.

Through bonding technology, they can be made to have a bonding rate of more than 90%.

However, the pearlescent pigments we use now have better performance, but they do not have such good warp bonding ability.

With bonding technology, only about 40% of the bonding can be achieved.

So, if you're doing mass production, when you're doing a lot of spraying, you're going to find a lot of color differences in a lot of places.

This is due to the pearlescent pigment, because of the different spray guns, or different distances, the powder rate is also different.

This results in different colors, resulting in color aberrations.

This is not a good sign for your car, although it doesn't have much of an impact on the overall quality.

However, for the Geely automobile brand, it will make consumers feel that you are not rigorous enough, the quality of materials is relatively poor, and the workmanship is sloppy. ”

Li Boshi nodded frequently.

"I've been taught, thank you very much to Mr. Zhang for explaining these things to me, if you don't understand some things, I always feel that he is very simple.

It turned out to be a metallic pigment, and there was so much knowledge.

No wonder Zhou Zhou said that your company's technical strength is among the top in the world.

Sure enough, from the perspective of Mr. Zhang's technical literacy, your company's technical strength can definitely be regarded as the top. ”

How to listen to it and start praising himself, Zhang Xiaofan himself felt embarrassed.

It is not wrong to say that the technology is top in the world, but there are many of these things, and they are not developed by themselves.

These technologies were brought over by Zhang Xiaofan from the future, and the developers of these technologies have nothing to do with Zhang Xiaofan.

Those technology pioneers don't know what they are busy with now, maybe they see the automotive coatings developed by Zhimei New Materials, and then catch up, so as to catch up with the technical level of Zhimei New Materials.

Or like any other technician, through counter-reasoning, or through some other way to get the technical recipe.

So as to sit back and enjoy the results, these things are just a drink and a peck, and there will always be a fixed number.

Technology in this world is like this, you copy mine, I copy yours.

See who has more resources and who has strong ability.

Coating technology is like this, after others know your formula, you can avoid patents by slightly modifying the formula here.

This is also why 95% of paint manufacturers have technical formulas, and even some advanced formulas, but they have never paid any penny of technology transfer fees.

So once a manufacturer develops a new technology, the first thing to do is to keep it secret, keep it secret, and keep it secret.

But there are too many smart people in the world, and the technical barriers are not necessarily how thick, especially some technologies developed by small companies, you will find that when you get the sample, you can clearly feel that you can actually do this technology.

It's just that it may not be so good, but the technical barriers are not necessarily as usual.

The two talked a lot, from cars to paints, including some car prospects.

"Mr. Zhang, do you really think so?"

"This is not only I think, many manufacturers around the world should know, this is definitely the future direction.

After all, oil reserves are limited, and of course it is undeniable that we can adopt other biogasoline, but one way or another.

Electric vehicles are definitely the best way to do the future, because they can achieve true zero pollution.

Of course, the pollution generated by hydropower plants is something that the power industry needs to improve.

For the automotive industry, electric vehicles are absolutely pollution-free.

Moreover, the after-sales service of electric vehicles is very simple, the maintenance cost is very low, and the operation cost is also very low.

If there is a very big breakthrough in battery technology, electric vehicles will also usher in a leap forward. ”

Zhang Xiaofan's words made Li Boshi suddenly fall into deep thought.

Obviously, the first thing that restricts the development of electric vehicles is battery technology.

If the range is not enough, few people will have the urge to buy it.

The other is the battery management system, which is still not advanced enough at the moment.

The battery itself is not a stable thing, so in the process of charging and discharging the battery, it is necessary to keep the overall current stable at all times.

Of course, the motor is also one aspect, but so far, the motor technology is still enough to be applied to electric vehicles.

"These things are not up to me, and I agree with the prospects of electric vehicles and the direction of his research.

In fact, many people know it, but technology is such a thing, so it's quite easy, and when you really do it, you will find that it is 108,000 miles away from what you think.

So I've always admired Mr. Zhang, but I've heard that your company's technology is brought out by Mr. Zhang. ”

Li Boshi is indeed very envious of Zhang Xiaofan, although now Zhimei New Materials is still a small enterprise compared to Jili Automobile.

But in terms of technology, Zhimei new materials have basically stood at the top of ordinary coatings, not to mention anything else, let's say this automotive powder coating, according to Li Boshi's understanding, now can be applied on a large scale only how to new materials.

There is only one in the whole world, so don't you need to say it!

However, although the scale of the current Geely Automobile is relatively large, compared with the entire world automobile system, whether it is scale or technology, the ranking is old.

So how not to envy!

Zhang Xiaofan didn't feel anything about this, after all, he was standing on the shoulders of several giants.

There is certainly a little bit of pride, but not conceit.
