How much does the thickness of the paint affect the performance of the car?

The paint finish of many cars is actually different, and now there are also metallic paints, but not all black cars are metallic. People think that metallic paint is actually harder and can be a little better than ordinary car paint. Do you know the difference between the thickness of the paint?

Many people think that it is better to have a thicker paint on the car, because in this case it is more wear-resistant, but is this really the case? Does the thickness of the paint affect the car?

How much do you know about car companies and the technology of current car paint? In fact, the thickness of the paint is mainly related to the current advanced technology, in the past, because the technology was not advanced enough, so the need for thick paint, but now the technology is developing rapidly, thin paint can also replace thick paint, the function is actually the same, so there is no bad car paint, the following will introduce you to the current paint.

In the past, there were actually four layers of paint on the car, consisting of primer, electrophoretic paint, intermediate coat paint, base paint and clear coat. And everyone knows that Germany's car manufacturing technology is very rigorous, and its paint thickness is relatively thick. In this case, people generally think that the German car is better, and the Japanese car is thinner, but there is actually no difference in quality, the Japanese car just removes the middle layer, in fact, the current technology has no middle layer for the car and the four layers are no different, and the formula of the knowledge paint is different.

Many people are worried about the impact of the thickness of the paint on the car, and they think that the paint will be more fragile than before and the scratch resistance will be affected by the following. But there is no impact on the current technology, because it can affect the hardness of the paint that can affect the scratching of Chengdu, when the three-layer and the four-layer are the same as the hardness of the car, there is no difference, this is mainly in the outermost layer of paint film. The outermost layer is the real impact on the car.

After talking about the difference between the thickness of the car paint, does the thickness of the car paint have an impact on the car, do you feel that you no longer worry about the problem of car paint, in fact, the technology is more developed now, so many things are changing, our car is the same, the equipment on the car is becoming more and more advanced, the thin and thick car paint is not scratch resistant has no direct impact, even if the previous four layers of car paint will be scraped when there is a crash.

In fact, the thickness of the paint is mainly related to the current advanced technology, in the past, because the technology was not advanced enough, so the thick paint was needed, but now the technology is developing rapidly, the thin paint can also replace the thick paint, the function is actually the same, so there is no bad car paint.

The power of the engine is distributed to the four wheels, which greatly improves the vehicle's handling and capacity.

It will not matter, the role of the car paint is the aesthetics of the car.

What doesn't make a difference is the aesthetics.

I think it will increase the aesthetics, and it doesn't have any effect.

There should be no difference, maybe a little more beautiful.

It doesn't have a direct impact, it's too much to underestimate the current technology.

It doesn't make a difference, it's just a beauty.

It doesn't matter much, after all, the paint is part of the car's appearance.

The thickness of the paint is related to the model, color, and specific partsIt is generally between 120 and 180 micronsThe hardness of the Mohs scale is only, and the thickness of the roof, door panels, and front lid varies slightly.

Automobile paint should not only have good mechanical properties, good fullness and high gloss, but also have good adhesion, high hardness and strong scratch resistance, and at the same time have excellent weather resistance, scratch resistance, gloss durability, and excellent gasoline, alcohol, acid, alkali and salt spray resistance.

Clause. First, it is for the cheapest pure entry-level economic mini car (the price of the naked car is less than 50,000 yuan), its paint surface can not be less than 90 m, our paint thickness requirements for this grade of models can be said to be relatively low, when the result is less than 90 m, it can be regarded as paint cutting corners.

Clause. Second, it is for any model with a price higher than 50,000 yuan: the minimum cannot be less than 120 m (hard index), if it is lower than 120 m, it can also be regarded as the manufacturer's cutting corners on the paint surface.

For most well-known brand cars, the thickness of the paint film is generally between 120 and 180 microns, and the thickness of the roof, door panels, and front cover varies slightly. Anything below 110 microns is a bit watery, and it's too thick and unnecessary. There are also individual imported luxury cars that are higher than 200 microns.

The thickness of the paint seems to be thicker, I remember that Japanese cars are generally 30-40um, while European and American cars are 50-60um, I am just not sure, I want to get a definite answer, so I asked this question; Generally, the paint surface of a car can withstand 7-8 polishes.

There are standard types of paint coatings for this car, and the corresponding paint film thickness is also different, generally in 40 60um; For details, see QC T484 automotive coating standard.

Well: There are many layers of car paint, and then there is a thick layer of paint under the exterior polishing paint.

It is related to the model, color, and specific parts, generally around 100 m, and the Mohs hardness is only equivalent to the hardness of 2-4h pencil lead.

Automobile body paint is the outermost coating of the vehicle, which is a direct reflection of the exterior decoration and anti-corrosion of the vehicle. In addition to the appearance design of the automobile body and the surface accuracy of the body processing (for example, the gloss of the arc surface or the protruding surface is better than that of the flat surface), the advantages and disadvantages of the gloss are also related to the matching process of the selected paint and surface coating. It is necessary to carry out careful coating design and have good coating environmental conditions in order to make the surface coating have excellent decoration.

At the same time, automotive coating is a high-level protective coating, and the resulting topcoat coating film must have excellent corrosion resistance, weather resistance and fracture resistance.

No, the paint surface can be maintained at a standard thickness, and it is useless if it is very thick, and it does not need to be too thick, so it will not play a role in protecting the car.

Of course not. If the paint is too thick, it is very bad for the car. On the contrary, the thinner the better, the better for the car.

No. The thinner and lighter the better, which will make the car more shiny and will also make the car more advanced.

No. This also has a degree, if it is too thick, it may crack, and if it is too thin, there is no better effect.

Abnormal.

The thickness of automotive paint is normal between 120 and 180 microns, and the hardness of Mohs scale is between to. Car paint is the paint sprayed on the body of the car, which is divided into four layers, the outer layer is the varnish layer, then the topcoat, and then the primer and electrophoretic plating.

Spraying paint on the body of the car can create a kind of protection on the surface of the car body, so that it will not be easily corroded, and it can also extend the life of the car and increase the aesthetics of the car. Generally, before the car leaves the factory, the manufacturer will set a variety of body colors, and the body color is determined by the paint applied to the body.

First: it is for the cheapest pure entry-level economic mini car (the price of the naked car is less than 50,000 yuan), its paint surface can not be less than 90 m, our paint thickness requirements for this grade of models can be said to be relatively low, when the result is less than 90 m, we can also regard it as a paint corner.

Second: it is stipulated for any model with a price higher than 50,000 yuan: the minimum cannot be less than 120 m (hard index), if it is less than 120 m, we can also regard it as the manufacturer's cutting corners on the paint surface.

The thickness of the paint is generally about 120-180 microns, so it is normal to use a paint film meter to detect the paint in the range of 120-180.

The average thickness of the paint is 136 microns, in the case of Mercedes.

The hardness of paint is measured according to the national standard hardness pencil, which can be divided into 17 categories from 6b to 9h, and the hardness of general paint is between b-3h. The hardness standard of ordinary car paint is 2h, and the hardness of special car paint is generally 2-5h.

In the industry, there is a saying that Japanese car paint is softer, German car paint is harder, this is not absolute, but also divided into specific models, the average hardness of Japanese car paint is 2-4h, and the average hardness of German car paint is between 3-5h.

The thickness of the automobile paint is limited by the minimum value of the paint thickness of the vehicle according to the national standard "QC T 484-1999 Paint Quality Standard". What is the minimum limit, that is, aside from the paint quality, that is, the paint surface of this car cannot be lower than how much um is qualified. According to this standard, the minimum value of paint surface is divided into the following reference standards:

1. For the cheapest pure entry-level economic mini car (the price of the naked car is less than 50,000), its paint surface can not be less than 90um, and our paint thickness requirements for this grade model can be said to be relatively low. Less than 90um is considered to be a paint cut corner.

2. For the standard of any model higher than 50,000 yuan, this standard should be improved: the minimum cannot be less than 120um (hard index). Less than 120um is considered to be a paint cut.

The thickness of the paint surface is also different for the same part of different models.

Different requirements are made for different models of cars, and the standard name is "QC T 484-1999 Paint Quality Standard".

It is stated therein: First: it is the standard for the cheapest pure entry-level economic mini car (the price of the naked car is less than 50,000), and its paint surface can not be less than 90um, and the paint thickness requirements for this grade model can be said to be relatively low. Less than 90um is considered to be a paint cut corner.

Second: the standard is for any model higher than 50,000 yuan, and this standard will be improved: the minimum cannot be less than 120um (hard index). Less than 120um is considered to be a paint cut.

The thickness of the car paint is only 20 m (20 m = 1 50 mm) and the Mohs hardness is only equivalent to the hardness of a pencil lead of 2-4 hours.

Very thin, this is related to the model, color, and specific parts, generally more than 100 m.

60 seconds a day, easy to understand the car, pay attention to the "spare tire to say the car".

Is it a quality problem that cracks after painting?
