The corrosion or discoloration of galvanized iron wire in the atmosphere caused by oxygen, moisture and other pollution impurities is called rust or rust. After galvanized iron wire rusting, it will affect the appearance quality, seriously affect the use, and even cause scrap, so galvanized iron wire must be properly kept and pay attention to rust prevention.

The use of electric welding mesh is very wide, can be used in many places. In the field of construction, especially the wall crack, has played a very important role, the traditional construction, is to put on mortar directly onto the wall, after such a long time, will appear fall off and fracture phenomenon, in order to prevent the occurrence of this phenomenon, must use welded wire mesh before rendering, welded wire mesh is fixed to the wall, above the plastering construction, Can ensure that the wall level for a long time, not easy to crack phenomenon.

After the corrosion of impregnated hexagonal wire mesh, the original characteristics will be lost, and the shape, color and mechanical properties will be changed, 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 is easier to rust than dry environment, 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 six-sided wire mesh, prolong the service life of the product.

The protective duration of the galvanized layer of large roll galvanized wire is closely related to the thickness of the coating. Generally speaking, in relatively dry main gas and indoor use, and in harsh environmental conditions, the thickness of galvanized layer needs to be very high. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. After passivation treatment of galvanized layer, a layer of bright old and beautiful color passivation film can be generated, which can significantly improve its protective performance.

Razor wire, also known as razor wire and razor net, is a new type of protective net. Blade barbed wire has beautiful, economic and practical, good anti-resistance effect, convenient construction and other excellent characteristics, at present, blade barbed wire has been widely used in many countries of industrial and mining enterprises, garden apartments, border posts, military fields, prisons, detention houses, government buildings and other countries of the security facilities.
