What is the difference between cold spray and hot spray?

Guardrail spray is divided into cold spray and hot spray two kinds. The cold spray layer is thin and has many defects. The thermal spray layer can remove moisture, increase the amount of powder, and increase the thickness of the coating, which is very beneficial to improve the service life of the guardrail in the outdoor.

When painting, the distance between the painting gun and the guardrail should be appropriate, generally 200mm. Adjust the electrostatic voltage of 60 to 80 kV, so that the compressed air does not contain oil, water and dust. Filter type recovery device to ensure that the powder does not overflow, reasonable recovery.

Commonly used guardrail spray ordinary pure polyester powder coating, curing temperature is generally 180 to 200℃, adjust the transport speed, so that the guardrail at this temperature continuous baking for 20 to 25 days. For the column, due to the larger wall thickness of the column, the baking time should also be appropriately extended.
