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. There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time.

The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.

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.

Poor pretreatment before electroplating; Bath temperature is too low; Poor quality additives or excessive additives and organic impurities can cause poor bonding. The quality of the additive also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the lattice and create stress, causing the coating to blister.

There is no need to carry out daily maintenance and maintenance when in use, which can not only save a lot of time, but also reduce the cost, but also has good stability, strong corrosion resistance, greatly extend the service life. According to the different technology is divided into different types, can be selected according to their own needs, has better flexibility and elasticity. The main function of annealing wire is to control its hardness, when the annealing wire is made of steel wire.

5, according to the wire diameter thickness to adjust zinc dipping time

The production process of stainless steel blade piercing rope is basically similar to that of galvanized blade piercing rope, and the blade size is usually determined according to the mold.

Many people do not know how to choose high quality cut wire, I will give you a detailed introduction. The raw material of cutting wire is divided into: stainless steel cutting wire, copper cutting wire, steel wire cutting wire, copper plated steel wire cutting wire, galvanized steel wire cutting wire, iron wire cutting wire, aluminum wire cutting wire and so on.

Hot dip galvanizing is also called hot dip zinc and hot dip galvanizing: is an effective way of metal corrosion, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel parts is attached with zinc layer, so as to play the purpose of anticorrosion. Hot dip galvanizing process: finished product pickling – washing – adding bath aid – drying – hanging plating – cooling – drug – cleaning – grinding – hot dip galvanizing completion. Hot dip galvanizing is developed from the older method of hot dip galvanizing. It has a history of 140 years since it was applied to industry in France in 1836. However, the hot dip galvanizing industry has been developed on a large scale in the past 30 years with the rapid development of hot dip galvanizing wire.

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.
