What Are The Semi-Trailer Painting Processes ?

Why do semi trailers need to be painted ? First of all, the structural parts of the trailer are steel, belong to the outdoor supplies, need to withstand the wind and sun, gravel impact, cargo wear paint and other all the time test. Therefore, the primary role of painting is to protect the semi-trailer.

So after the above you should understand, a trailer is good, in addition to its own steel and configuration, paint is often a measure of a trailer durable one of the criteria. Good paint can extend the life of the semi-trailer paint, painting process is divided into manual painting, electrophoresis paint and electrostatic powder spraying process. The following are the advantages and disadvantages of these three painting processes.

Manual Painting

This method process is simple and low cost, so the general quality of the trailer will use manual painting. And the low cost process must have its defects

1. the service life is not more than 3 years

2. dead ends in hidden places cannot be painted.

3. uneven thickness and large gap of paint surface.

4. loss and waste of energy, not environmentally friendly.

5. easy to paint off after bending and extrusion, poor corrosion and rust resistance of the paint surface, not durable.

Electrophoretic Paint

The cost of electrophoresis paint is much more expensive compared with manual spraying, but after electrophoresis painting of semi-trailer, any dead corner will be covered by paint, and the paint surface of the trailer after electrophoresis is thin and even, the most important thing is that after electrophoresis of semi-trailer, corrosion resistance and wear resistance are greatly improved.

Electrostatic Powder Spraying

1. Uniform spraying of coating surface and bright color.

2. High spraying quality and strong coating adhesion ability.

3. Improve labor productivity, easy to realize automatic flowing operation, save labor cost.

4. Substantial improvement of the utilization rate of paint, energy saving and environmental protection.

These are the advantages and disadvantages of these three painting processes, and the next article will introduce the types of paint for semi-trailers.
