Knowledge About Thermal Spray Zinc

Thermal spray zinc, I believe everyone is very familiar with it. Today, the editor will come to learn with you about the knowledge of thermal spray zinc.

In general, the principle of thermal spray zinc is to first use high-pressure air and pipelines to blow sand to the surface of the workpiece to remove rust and oxide skin on the metal surface, and at the same time increase the adsorption force of the surface to increase the adsorption force of the thermal spray layer, and then use oxygen, acetylene or electric heat source ( Large workpieces are heated by electricity, and small and medium-sized workpieces are heated by oxygen and acetylene. The zinc is atomized and sprayed onto the metal surface at an ultra-high speed through compressed air and special tools (spray guns).

The anti-corrosion effect is maintenance-free for more than 20 years due to the sandblasted hemp to ensure the effective adhesion of the coating. Although the initial investment is larger than that of spray paint, the spray paint needs to be maintained after two or three years. In the long run, the manpower and material resources are much higher than that of thermal spray zinc. The entire construction process of thermal spray zinc anticorrosion is divided into four items: surface treatment → spray zinc → sealing treatment → quality inspection.

When we're done, we're going to overhaul it.
