Arc spraying zinc-one of the representative thermal spraying technologies
It has the characteristics of strong practicability, fast construction speed, and excellent quality. For the steel structure parts exposed to the outdoors and the ocean atmosphere for a long time, the arc spray zinc and aluminum spray have good corrosion resistance. The coating has the cathodic protection effect of the sacrificial anode, and long-term corrosion protection for the substrate.
Arc zinc spraying belongs to the category of thermal spraying technology. The so-called arc zinc spraying, in short, is through the arc spraying zinc equipment, and under the action of electric current, with the help of high-pressure air, the hot melted pure zinc wire liquid is shot at high speed to the coated object ( The coated object can be steel, metal alloy, ceramic, plastic, etc.), a dense and uniform zinc layer is formed on the surface of the coated object, so that the coated object has anti-corrosion, decoration or a special purpose construction method.
