The surface coating of galvanized wire can be seen whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire. High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer, we can generally judge the quality of galvanized wire.

The methods to control the thickness of galvanizing are as follows: you can slow down the lifting speed of the workpiece, control the time of galvanizing as far as possible, add the appropriate amount of thinning alloy, reduce the thickness, and improve the temperature of hot-dip galvanizing. But consider the zinc pot, iron pot should not exceed 480 degrees, ceramic pot can be 530 degrees, which can reduce the time of zinc immersion.

The impregnated hexagonal wire mesh will lose its original characteristics after corrosion, and will change in shape, color and mechanical properties, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated hexagonal wire mesh, prolong the service life of products.
