Post time: 23-06-22- Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer. When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.

- Purpose of galvanized hexagonal net: building wall fixed, heat preservation, heat insulation; Power plant tied pipe, boiler warm; Anti-freezing, residential protection, landscaping protection; Raising chickens and ducks, isolating chicken and duck houses, to protect poultry; To protect and support seawalls, hillsides, roads and Bridges and other waterworks.
Post time: 21-03-23- Generally speaking steel does not rust easily with chromium content of 10.5%. The higher the content of chromium and nickel, the better the corrosion resistance, such as 304 material nickel content in 8-10%, chromium content of 18-20%, such stainless steel in general is not rust.
Large roll galvanized wire is the use of low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes, in the use of is more widely. The temperature of large roll galvanized wire for electroplating should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.
This process has no mold, low processing cost, easy forming, can process a variety of shapes and other characteristics are widely used. But the products of the guardrail are powder impregnated plastic. According to whether it needs heating, it is divided into hot dipping and cold dipping. According to the raw materials of dipping, it can be divided into liquid dipping and powder dipping. Hot-dip galvanizing, as a metal anticorrosion method, is usually to put the steel structure to be derusted into the zinc liquid at about 500℃, so that the zinc layer is attached to the surface of the steel structure.
Post time: 20-07-22Wire flexibility and elongation is good, can withstand the pressure of mechanical operation, in our country’s industry has played a very important role. There are many kinds of iron wire, the most common is to give black iron wire, galvanized iron wire. The corrosion resistance of the outer coating is effectively improved, but the phenomenon of crevice corrosion will be found after long-term use.
In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.

After the corrosion of impregnated hexagonal wire mesh, the original characteristics will be lost, and the shape, color and mechanical properties will be changed, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated six-sided wire mesh, prolong the service life of the product.
Stainless steel blade barbed wire production process is similar to galvanized blade barbed wire production process, usually according to the mold to determine the size of the blade.
Hook mesh we usually see everywhere, in fact, hook mesh is a kind of fence, like the highway, stadium fence, road fence, etc., have hook mesh. So what are the effects and advantages of the use of hook net?
Products are widely used in construction, handicrafts, wire mesh, highway guardrail, product packaging and daily civilian and other fields. Galvanized wire is divided into hot galvanizing, cold galvanizing, electric galvanizing, hot galvanizing price is high, the price of electric galvanizing is low. Hot dip galvanizing is not easy to rust, electric galvanizing is easy to rust, this is a simple discrimination. 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.
- Determine the size of the cage based on the actual size of the dog as an adult. In general, the cage should be three times the size of the dog’s body, with enough room for the dog to turn around and so on.
- Through drawing forming, pickling rust removal, high temperature annealing, hot dip galvanizing. Cooling process and other processing. Electric galvanized iron wire selection of high quality low carbon steel as raw material, after drawing, galvanizing and other processes completed. It has the characteristics of galvanized layer, strong corrosion resistance and strong galvanized layer, etc. Electric galvanized iron wire is widely used in construction, highway wall, tie-flower, net weaving and other industries.
- Six: spray blade barbed rope features mechanical strength, adhesion, corrosion resistance, aging resistance, etc., will greatly increase the service life of the barbed rope, anti-UV, anti-aging weathering.
- 4. When the dog is tired or nervous, it can enjoy its own private space in the cage and let it have a good rest.
- Alias: gabion mesh, heavy hexagonal mesh, ecological mesh, wire mesh, etc.
There are many important details that need to be paid special attention to during the production of barbed rope or blade barbed rope by the barbed rope factory. If any improper, it will cause unnecessary losses.

Post time: 01-09-22If 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.
