Problems solved by technology

[0002] After the explosion-proof tools are made into finished products, they must be surface treated. Some use ancient pickling, boiling dry, and some use painting or electroplating, which still cannot solve the oxidation problem of explosion-proof tools. During use or storage and transportation, There are still green moss-like changes, and some even reduce their unique explosion-proof performance after such surface treatment

Embodiment

[0006] Example: A copper alloy explosion-proof tool surface spraying process. First, the finished explosion-proof tool is transferred to a polishing workshop for careful removal of contamination, and then it enters the surface treatment workshop, where the tool is suspended in a dry powder spraying room. When multiple workpieces are treated together The distance between the workpieces is not less than 75mm, the horizontal height is kept at 900mm, and the red epoxy polyester mixed powder coating is sprayed on the surface of the tool with an electrostatic generator. The film thickness is 6-8mm, and the electrostatic value is controlled at 40-60kv After resting for 2-3 minutes, it is transferred to the receiving frame through the free track, and slowly slides it into the drying furnace at a constant speed. After heating to 180 °C, it is kept for 25-30 minutes. After completion, it is transferred to the polishing workshop again, and the working contact Surface polished.

Abstract

The invention relates to a spraying process for explosion-proof tool surface. At first, explosion-proof tool is sent to polishing workshop for careful pollution removal; then the product is sent to the surface treatment workshop and is hung in dry powder injection room. The distance between products is less than 75mm. The horizontal height maintains in 900mm. red epoxy dion mixed powder coating is sprayed on product surfaces by electrostatic generator. The thickness of added film is 6-8mm and electrostatic value is controlled in 40-60Kv. After resting for 2-3min the product is shifted to receiving frame by free railway and is sent to drying furnace slowly in sliding with uniform speed. After temperature is increased to 180deg.C the temperature is maintained for 25-30min. After it the product is sent to the polishing workshop again and working contact face of product is polished. The invention is provided with improved explosion-proof performance of tool, beautiful appearance, near zero oxidation degree, improved surface hardness and adhesive force.

Description

technical field [0001] The invention relates to a surface spraying process of a copper alloy explosion-proof tool. Background technique [0002] Explosion-proof tools must be surface-treated after they are made into finished products. Some use ancient pickling, boiling dry, and some use painting or electroplating, which still cannot solve the oxidation problem of explosion-proof tools. During use or during storage and transportation, There is still green moss-like change, and some even after such surface treatment, its unique explosion-proof performance is reduced. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a surface spraying process for copper alloy explosion-proof tools. [0004] The technical scheme of the present invention is: a copper alloy explosion-proof tool surface spraying process, which is characterized in that: first, the explosion-proof tool is subjected to surface decontaminat...
