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.

The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.

Galvanized iron wire will rust, mainly and the thickness of galvanized layer and the use of the environment, galvanized iron wire is also divided into cold galvanized iron wire and hot galvanized iron wire, in general, hot galvanized iron wire galvanized layer is thicker, rust prevention time is longer, generally can be 7 or 8 years without rust. If the galvanized layer is damaged, or long-term use in a humid environment, it will accelerate the rust time of galvanized iron wire.

Welding mesh is also known as external wall insulation wire mesh, galvanized wire mesh, galvanized welding mesh, wire mesh, row welding mesh, touch welding mesh, construction mesh, external wall insulation mesh, decorative mesh, barbed wire, square eye mesh, screen mesh, anti-crack mesh. Stainless steel welding net, is made of high quality stainless steel wire row welding, more acid resistance, alkali resistance, solid welding, beautiful, wide use and so on.

Galvanized hook mesh standard is thorough, mesh planning: 3cm-20cm, silk planning: 1.2mm-4.5mm, galvanized hook mesh 6000 square meters, some standards are available. Benefits: The selection of low carbon steel wire, surface for cold galvanized (electric galvanized) hot dip galvanized anticorrosion treatment, mesh wire strong, strong protection, long anticorrosion time.

In view of this situation, many manufacturers are committed to ensuring the corrosion resistance of titanium and titanium alloy under the premise of increasing the hardness of titanium alloy, and surface carburizing is one of the typical processing technology means. Similar to the surface carburizing treatment of steel, the surface carburizing treatment of titanium alloy is to make the active carbon atoms, diffusion to the internal of titanium alloy, the formation of a certain thickness of higher carbon content of the carburizing layer, after quenching and tempering, so that the surface layer of the workpiece to obtain high carbon content of titanium alloy wire.

Immersed six edge barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, specifically, is prone to fracture, lose the original protection function. Corrosion usually metal corrosion has three types: physical, chemical corrosion and electrochemical corrosion, and corrosion depends on the chemistry of the metal itself and the organizational structure, still have relationship with the surrounding medium, such as wet environment than dry environment is easy to rust, more less than the impurities of impurities is easy corrosion, high temperature conditions than under the condition of low temperature corrosion, etc. After understanding these, we can effectively prevent the corrosion of the six sides of the wire, prolong the service life of the product.

The main difference between the two is the carbon content. The carbon content of iron is 2.11 percent or greater, while the carbon content of steel is 2.11 percent or less. The iron carbon alloy with carbon content above 2.11% is cast iron (pig iron), which is basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different. The content of harmful impurities such as sulfur and phosphorus in steel is smaller. Steel wire general color focus, iron wire color light point, white point.

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.

The physical methods mainly include manual rust removal and mechanical rust removal, chemical rust removal is generally the use of pickling method, practical application, usually according to the appearance of the workpiece rust status and different post-treatment process, choose different rust removal methods, among which pickling rust cleaning is more commonly used. That is, the iron and steel workpiece with oxide skin or rust is etched in the acid lotion, mainly to remove the oxide or rust layer on the surface of the steel.

What’s the difference between cold galvanized wire and hot galvanized wire? It is mainly different production process. Cold galvanized iron wire, also known as electric galvanized iron wire, is the use of electrolytic galvanizing process, and hot galvanized iron wire is the use of hot penetration galvanizing process. Compared with the two, hot dip galvanized iron wire thick coating, high zinc content, has stronger anti-corrosion and anti-rust effect. Similarly, the price is also higher, cold galvanized iron wire and hot galvanized iron wire which good? Mainly for the use of scenarios and requirements to choose appropriate galvanized iron wire, appropriate is better.
