Paint thickness tester Used in Auto Industry
1. Car paint types
Common car paints on the market are roughly divided into three types. They are ordinary paint, metallic paint and pearl paint.
Ordinary lacquer is the most common one. It is composed of resins, pigments and additives. Metallic paint is added with aluminum powder, copper powder and other metal particles on the basis of ordinary paint, so it looks shiny in the sun. Pearlescent paint is not very different from metallic paint. Mica particles are added on the basis of ordinary paint. The color change will occur under different angles of irradiation and the light reflectivity is better. Linshang LS220 paint thickness tester can be used to detect the automobile paint film thickness.
2. Car paint thickness
Those who have researched second-hand cars should know that judging whether second-hand cars have had an accident or not. An useful method is to use paint thickness tester to detect the car paint thickness. If the car paint is re-made after an accident, the general car paint thickness will be more than 200 microns. And the general original car paint thickness is 110 microns to 140 microns. Therefore, it is not that the thicker the car paint, the better. And the degree of wear resistance has nothing to do with the thickness of the car paint.
The car paint on the previous car actually has four layers, consisting of the primer electrophoretic paint, the middle coat, the color paint layer and the varnish layer. The thickness of ordinary German cars is slightly thicker than that of Japanese cars. In this case, most people think that German cars are better, but there is no difference in quality.
Due to the advancement of the current material technology, the same effect can be achieved without using multiple layers. At this time, the original middle coating is removed, and the corresponding car paint thickness is also reduced to a certain extent, which is actually not It is cutting corners.
LS220 paint thickness tester is a professional instrument for detecting the thickness of automobile paint film. The paint thickness tester has the digital function and digital of analog signal terminal. Probe technology can ensure the stability of the paint thickness tester sensor signal and provide good test accuracy for the paint thickness tester.
3. Car paint vanish coating
The hardness index mainly depends on the "varnish coating" in the paint layer, which is the outermost layer. In other words, the previous four-layer paint is now a three-layer paint, which is much thinner than before, but this does not affect the scratch resistance of the car paint. The general car paint hardness is H, the harder is 2H and some high-end car surface paint may be harder, even reaching the level of 3H or 4H, almost comparable to the hardness of crystal plating.
Therefore, the original car paint thickness has nothing to do with the quality of the car. The current car technology is more developed, not only the car paint thickness has changed, but many places on the car are changing. The car paint thickness and whether the car is scratch-resistant have no direct effect, even if the previous four-layer car paint will be scratched in the event of a collision. The paint thickness tester that measures the car paint thickness is also called a coating thickness gauge, which is a special instrument for detecting the automobile paint surface thickness.
The covering surface of the car is basically covered with a paint coating. The paint surface thickness can be directly judged by the paint thickness tester to determine the sheet metal and spray paint of a car. The size of the vehicle accident damage can also be indirectly determined. The LS220 paint thickness tester is small and is particularly suitable for carrying around when going out for inspection. And it has the characteristics of fast test speed, stable test data and high measurement accuracy.
