Laymen may not know the surface treatment process of zinc steel guardrail, but experts know it clearly. When consulting manufacturers, they will ask whether their guardrail is plastic sprayed guardrail or spray painted guardrail. In fact, the current zinc steel guardrails are plastic sprayed guardrails, and the painted guardrails are generally iron guardrails, which is a simple coloring of the guardrail surface.

 

 

The raw material of zinc steel guardrail spraying is a kind of solid powder. It melts on the surface of various guardrails and fences at high temperature, and the adhesion protective layer is better. Paint is a kind of liquid. Liquid paint can be brushed on the object surface with a brush or sprayed on the object surface with a spray gun. However, when painting, if you are not careful, the paint will flow down like water, resulting in water lines or uneven and bumpy phenomena. However, some skilled workers will find it difficult to distinguish plastic spraying and paint.

 

 

The process principle of plastic spraying is to use the corona discharge phenomenon to make the powder coating adsorb on the workpiece. The process is as follows: the powder coating is sent to the spray gun by the powder supply system through compressed air gas, and the high voltage generated by the high-voltage electrostatic generator is added at the front end of the spray gun. Due to corona discharge, dense charges are generated near it. When the powder is ejected from the gun nozzle, charged coating particles are formed, which are attracted to the workpiece with opposite polarity under the action of electrostatic force, With the increase of sprayed powder, the charge accumulates more. When it reaches a certain thickness, due to electrostatic repulsion, it will not continue to adsorb, so that the whole workpiece can obtain a certain thickness of powder coating, and then the powder is melted, leveled and solidified by heating, that is, a hard film is formed on the surface of the workpiece.

 

 

Compared with the traditional spray painting process, electrostatic spray technology has significant advantages, no pollution to the environment and no toxicity to human body; The coating has excellent appearance quality, strong adhesion and mechanical strength; The curing time of spraying construction is short; The corrosion and wear resistance of the coating is much higher; Some construction sites have clearly proposed that electrostatic plastic spraying process must be used; In the process of electrostatic powder spraying, there will be no common flow phenomenon in the painting process, and there are many varieties and rich colors, which can be integrated with various environments. Different styles can be selected according to the regional environment to highlight personality.

 

 

If your budget is enough, it is recommended that you use zinc steel guardrail, which has a long service life and does not require a lot of manpower, material and financial resources for subsequent maintenance. Plastic sprayed guardrail also has less pollution to the environment. Now we advocate building a green living environment and purifying your and my living environment. We also need to start from ourselves. Choosing plastic sprayed zinc steel guardrail is your support for environmental protection!
