The production process of large coil galvanized wire is relatively simple. The wire after cleaning is put into electroplating solution first. Of course, the plating solution should contain zinc oxide, a direct current of steel, another zinc plate in the plating solution. The zinc is transferred to the surface of the steel as a molecule. If it shows a bright and beautiful color, the wire is coated with zinc.

Electric galvanized wire direct selling is in the plating tank through the current one-way to gradually zinc plating on the metal appearance, the 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, the production cost of electric galvanizing is lower. 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 galvanizing shiny white.

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.

What kind of wire mesh fence should be used for chickens, ducks, geese and other light poultry? The so-called good refers to the high cost performance, that is, the use effect can be achieved, such as the size of the mesh, the size, etc., and the cost can be reduced to the greatest extent.

Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.

After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.

A pet carrier can be used as an indoor and outdoor pet house. The dog cage is equipped with a fixed food basin and drinking water, and the foot plate pet cage rubber pad has bayonets on four sides to be collated. According to the cage size can be splicing, cutting, disassembly is convenient, easy to clean, can solve the puppy in the ordinary cage foot clamping problem, prevent the puppy in the development of adverse reactions. The dividers are breathable and comfortable, and can be used as heat shields for pets in summer. A puppy with small feet that does not hold its feet or pinch its feet.

The external environment has great influence on the preservation of galvanized wire mesh. In the rainy season, it is necessary to pay attention to the air humidity of the workshop, warehouse and other departments. It is recommended to use a humidifier. Usually, the moisture absorption of book paper is larger than that of powder paper, and the pH value is higher. Generally speaking, in the normal environment of storage wire, storage time of two years is not corroded wire phenomenon. However, it should be noted that in the process of handling the iron wire, it should be handled gently to avoid the position of the coiling coil, which will cause the smooth pulling of the wire and affect the production.

If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.

The technical term “galvanizing” means that the metal has been specially treated with zinc. Essentially, it’s wire covered with a very thin layer of zinc. It is because of this thin layer of zinc that galvanized wire has many characteristics. Zinc can be galvanized by dipping the wire into a zinc bath or by electroplating.
