The main component of plastic spraying material is polyester, which belongs to high temperature electrostatic spraying. The purpose of plastic spraying is to improve the anti-corrosion ability of objects. The color of plastic powder depends on one's own preference.

Most of the noise barriers are installed in the factory workshop near the residential area, which can be seen by people in and out. After the installation of the noise barrier in the residential area, it can not be like an airtight wall. Therefore, people have to work hard on the material and color. In the past, they used to use blue, which is the same as the sky, and the world is one. Also useful green, green eye. But now when we buy noise barriers, most of us appeal to use gray. Why are we keen on gray? Let's see if it makes sense for noise barrier manufacturers to analyze it.

Gray is not "color", can not be called "color". Gray is always measured by "degree", because its quality is only the reflection of non color, that is, the share of black and white is different. For example, 18% black is called 18 degree gray. If we say that the gray level, visually play for the difference between light and shade. Gray can shine other colors, white in strong light, and refract similar light source against other colors. Color can set off mood and artistic conception, can represent fashion, indifference, sports, this is a kind of charm.

In the eyes of artists, gray is always a pretty secret color. Its rich sense of hierarchy and color makes people addicted. Gray is tolerant, broad and low, which is a kind of quiet to comfort the people.
