Galvanized hexagonal mesh weaving process: double stranded hexagonal mesh, can be divided into three screws and five screws.

In summary, as a commonly used anticorrosive material, electrogalvanized wire has good corrosion resistance. Its corrosion resistance mainly depends on the thickness, uniformity and structure of zinc layer, substrate material and environmental conditions and other factors. Through reasonable electroplating process and material selection, the corrosion resistance of electrogalvanized wire can be improved and its service life can be extended.

Plastic coated electric welding net: PVC plastic coated electric welding net is a kind of tall welding net, plastic coated electric welding net picture on the upper part of the protective barbed net, network cable is galvanized steel wire, plus PVC plastic treatment, in the protection of beautiful at the same time, ensure the firm and durable. Material: low carbon steel wire, PVC plastic coating manufacturing process: steel wire after welding plastic coating, can also be separate electroplating, hot plating and plastic coating. PVC plastic coated electric welding net use: industrial, agricultural, municipal, transportation and other industries of fence, decoration, protection and other facilities. PVC plastic coated electric welding mesh features: good corrosion resistance, strong weather resistance, anti-aging, beautiful and generous. Installation is simple and quick.

The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.
