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.

Electro galvanizing shaft wire direct is in the electroplating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with hot dip galvanizing, electric galvanizing has lower production cost. The difference between cold galvanizing and hot galvanizing: the difference between cold galvanizing and hot galvanizing is that the amount of zinc is different. They can be identified from the color. The color of cold galvanizing is shiny silver white with yellow. Hot dip galvanized shiny hair white.

The application of electric welding mesh is more widely, at present, it has replaced the use of other parts of the screen, the cost of electric welding mesh is low, the production speed is very fast, so it is very popular. The treatment required before galvanized welding mesh is recrystallization annealing, because the welding mesh must maintain an oxide and no other impurities of pure iron active surface, if you can’t keep its surface clean will lead to poor galvanized effect, galvanized layer and iron material is not tightly combined, so this step is necessary.

5, after the light plating should be carried out light treatment.

Now more and more people are buying the barbed rope, but there are often a lot of people do not know the specifications of the blade barbed rope when they buy, here is to introduce the specific characteristics of the blade barbed rope.
