The electrophoretic paint process used in the trailer is analyzed!

Why should the trailer be painted

Before introducing the electrostatic spraying process, Xiaobian would like to tell you why the trailer is painted: First of all, the structural parts of the trailer are steel, which belongs to outdoor products, as long as it leaves the factory, it will have to withstand the test

Therefore, the primary role of spray paint is to protect the trailer, the paint on the surface of the general trailer belongs to the hardware paint, the internal structural parts are first pickled, passivated, baked and then sprayed, and then baked at a high temperature of 200-250 degrees, which forms a commonly known spray paint on the surface of the car; After the surface of the steel (spray paint) is painted, the surface paint can resist acids and alkalis, thereby extending the life of the trailer Paint coatingol.

In addition, if customers who buy trailers like different colors, or different manufacturers have different effects, then the painting process can also meet a variety of people who

Therefore, after the above, everyone should understand that a trailer is good or not, in addition to its own steel, the paint surface is often one of the criteria for measuring the durability of a

Previously, manual painting was used to paint the trailer, which was simple in process and low in cost, so the general quality of trailers would use manual painting

It is not an exaggeration to say that a good trailer, if manual painting is used, then the paint surface can last for three or four years, and then it is very difficult

Interest in electrophoretic paint

Therefore, electrophoretic paint came into being, since the 1950s, the first electrophoretic coating process line has been put into use in the automotive industry, and gradually popularized, the technology is becoming more and more mellow

How electrophoretic paint works

Electrophoretic paint, also known as electrophoretic paint, there are many people who still use the name of "electrophoretic paint" instead of "electrophoretic paint"

Electrophoretic coating is to immerse the conductive coating in a relatively low concentration of electrophoretic coating tank diluted with water as an anode (or cathode), and set up its corresponding cathode (or anode) in the tank, after indirect direct current at both poles for a period of time, a special coating method

The advantages of the trailer using electrophoretic paint

Because it is immersed in the paint, and it is through the adsorption of positive and negative electrons, so the trailer coated by electrophoresis, the body will not have a "hidden place", any dead angle will be covered by paint, and the trailer paint surface after electrophoresis is thin and uniform, and most importantly, the paint surface is really made into the first protective line of the body!

In fact, after the trailer passes electrophoresis, although the corrosion resistance and wear resistance can be improved, the lift is not big, and it depends on another thing topcoat process
