The derusting steel parts are immersed in the melted zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to achieve the purpose of anti-corrosion. The surface of galvanized wire coating can see whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire.

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.

The silver powder is actually a mixture of aluminum powder and polymer after painting the film, the film is brittle, easy to appear adhesion problems, and corrosion resistance is also slightly poor. Galvanizing refers to the surface of metal, alloy or other materials coated with a layer of zinc to play the role of beautiful, rust prevention and other surface treatment technology. Zinc dissolves easily in acids and also in bases, so it’s an amphoteric metal. Zinc changes little in dry air.

Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be prevented from being used in some outdoor guardrail or fence, especially on handicrafts, handicrafts are also of great use, galvanized iron wire, the surface is not easy to rust and oxidation. Now many hardware manufacturers produce iron wire, and iron wire is very easy to rust, if you need to use in outdoor or humid places, generally customers will require the use of galvanized iron wire equipment to give the wire a layer of zinc, the thickness can be determined according to user requirements.

Annealing wire is widely used because it has a good elasticity and flexibility, in the annealing process can be good control of its hardness, it is mainly made of iron wire, more often used in the construction industry binding wire use. In the production of the wire factory, annealing wire will be processed according to the properties of the material, according to the needs of different to change its hardness degree, can make it has more advantages, can reduce the consumption of metal, reduce the cost of production.

Cold wire drawing is a kind of cold processing of metal. The raw material is wire rod, which is produced by peeling, galvanizing and other processes. Galvanized cold drawing is used more in building materials. Its testing standards are also different. The strength of cold drawing is relatively high. Because of the high strength of steel, it plays a very important role in construction. It saves the construction steel in building materials, and also reduces the cost of the project. It also plays a very important role in the structure of concrete.

Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, The softness is also very uniform, the color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry, etc.

Now large roll galvanized wire in our life the use of more and more, to galvanized wire products bring a great market, galvanized wire products are more and more types. The surface coating of good quality galvanized wire is continuous and smooth. When the plating parts are installed and combined, there can be no flow hanging, slag or drop remaining, and no surface defects such as iron exposure. Good quality galvanized wire, coating must be uniform, roughly uniform in copper sulfate solution soaking five times without exposing iron. And with hammering test does not bulge, do not fall off. This is a good galvanized wire should have characteristics.

The application range of positive and negative twisting barbed rope is also very wide, is a good choice for purchasing barbed rope, then positive and negative twisting barbed rope compared with other barbed rope advantages? The following Haorong barbed rope factory for you to introduce the positive and negative twisting of the three advantages of barbed rope

If the surface of galvanized wire is black and the galvanized layer is thin and uneven, the galvanized wire is partly because the inventory storage time is longer, but also because the production technical requirements of galvanized wire do not meet the standard and lead to the quality problems of galvanized wire. According to the use of galvanized wire is different, galvanized wire has soft and hard, then the galvanized wire used for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, and it can be easy for workers to operate.
