  • In addition, the corrosion resistance of hot-dip galvanized wire will also be affected by other factors. For example, in different environments, especially in some special chemical environments, such as acidic or alkaline environments, the corrosion resistance of hot-dip galvanized wire may be affected to a certain extent. At this time, it may be necessary to use other materials that are more resistant to corrosion to replace the hot-dip galvanized wire.

  • 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.

  • The technical term “galvanized” means that metal has been specially treated with zinc. Essentially, the wire is covered with a very thin layer of zinc. It is this thin layer of zinc that gives galvanized wire its many properties. Galvanizing can be done by dipping wire into a pool of zinc or by electroplating.

  • After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron in the dry air is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements, its production cost is lower, use and scale is wider, better protection function, so it is an important material for iron and steel parts in a strict working environment.

  • The wire mesh is finished by fine welding of active welding equipment. The material can be divided into cold drawing wire, hot dip galvanized, cold galvanized, dip plastic and so on. To be used for bridge reinforcement, deck paving, building reinforcement, etc.

  • The material of wire mesh can choose galvanized wire, stainless steel wire, copper wire, coated wire, lacquer wire, etc., different materials are used in different fields, such as construction, culture, decoration, etc.

  • Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.

  • “At present, many international well-known pet manufacturers have also seized the huge business opportunities of the pet economy, and they continue to develop high-tech pet products, which are favored by consumers.” China’s pet industry should constantly introduce new varieties, strengthen research and development of pet food and supplies, and improve the content of science and technology to win a place in the market competition, an industry insider said.
