Application of Anti-corrosion Paint in Automobile Industry
Metal is a material that is easy to rust and oxidize. Before use, manufacturers will paint a layer of anti-rust paint on the metal surface. Anti-corrosion paint is a kind of surface used to protect objects from corrosion. This material is often used in our lives, such as cars, computer cases, shelves and so on. This article mainly explains the application of anti-corrosion paint in the automotive industry.
The car has a total of 4 layers of paint, from the inside to the outside: varnish, color paint, middle coat and electric pulse layer. You can use the paint thickness detector to measure the car paint thickness.
Varnish: improve the glossiness of the car paint surface and block a small amount of ultraviolet rays and prevent slight scratches; color paint: color paint layer, giving people the most intuitive color experience.
Intermediate coating: It has the function of connecting the color paint and the electric pulse layer. At the same time, it can resist ultraviolet rays and protect the electric pulse layer; the electric pulse layer: can protect the car body. It has the functions of anti-rust and improving the bonding force of the paint layer.
For the car, if the wound is varnish, paint and middle coat, it can be repaired. But once the electric pulse layer is injured, it cannot be repaired, because the repair of the electric pulse layer requires the entire car shell to be placed.
So once the damage to the electrical pulse layer is repaired, the possibility is very small. Anti-corrosion of automobile metal is important, but in the process of automobile anti-corrosion, the thickness detection of anti-corrosion coating on the automobile metal surface is also an indispensable step. Measuring the coating thickness with a paint thickness detector is one of the most important quality inspection indicators for automotive anti-corrosion coatings.
Paint thickness detector, also known as coating thickness gauge, is a special instrument for detecting the paint thickness on the surface of the automobile substrate. The covering surface of the car is basically covered with paint. Using a paint thickness detector to detect the paint surface thickness can directly determine the sheet metal and spray paint of a car. It can also indirectly determine the vehicle accident damage.
The LS220 paint thickness meter has a small size and is particularly suitable for carrying around when going out for inspection. It has the characteristics of fast test speed, stable test data and high measurement accuracy. Linshang LS220 paint thickness meter adopts magnetic thickness method and eddy current thickness method, which can be used to measure the non-magnetic coating thickness on the magnetic substrate. It can also be used to measure the non-conductive coating thickness on non-magnetic metal surfaces.
