The aluminum panel is the cart, ordinary nylon plate, the wheel is not conductive wheel, why use aluminum surface will be static, but not in the nylon plate, not easy to produce electrostatic in high resistance material?
The problem is on the oxide film or coating of the aluminum profile!Aluminum is very lively! Very easily in the air and oxygen, carbon dioxide, water oxidation and galvanic reaction generated! White aluminium hydroxide and aluminum carbonate! So that its surface will lose luster! In order to solve this problem! Is usually on the surface of aluminum shaped material is covered with a layer of very thin oxide film or electrostatic synthesis there are also cover coating thin polyester film!! this makes the surface and is completely isolated from the air!
Electrostatic powder spraying on aluminum surface is not to prevent static electricity, it is to use the static electricity to spray the powder on the surface of the aluminum.
To protect its surface finish!These thin film aluminum surface coverage of excellent conductivity and it is insulated! Then in normal environment and similar objects formed aluminum will static capacitance effect! This principle is that it can form the electrostatic charge accumulation!
