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.
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.
Wire mesh production of general selection of low carbon wire, after fine and accurate active welding equipment processing, the selection of galvanized process surface treatment. After the completion of the product, the net surface is smooth and regular, good integrity, strong and consolidated, even if part of the choice or pressure will not appear lax phenomenon.
The large roll of galvanized silk should be coated with oil, the fiber core is dipped in oil, and the grease should be able to protect the fiber core from decay and corrosion, the iron wire moistens the fiber, and lubricates the wire rope from the inside. The surface is coated with oil so that all the wire surface in the rope strand is evenly coated with a layer of anti-rust lubricating grease, which is used for the mine rope with friction lifting and mineral water, to be coated with black grease with increased wear and strong water resistance. Other uses are coated with red oil oil with strong film and good rust resistance, and require it to have a thin oil layer, which is easy to keep clean during the operation.
The application of electric welding mesh is more and more widely, the technology is gradually mature, electroplating rust prevention, plastic coated treatment, used for breeding, grille, plus the frame to make a fence, etc.
The corrosion or discoloration of galvanized iron wire in the atmosphere caused by oxygen, moisture and other pollution impurities is called rust or rust. After galvanized iron wire rusting, it will affect the appearance quality, seriously affect the use, and even cause scrap, so galvanized iron wire must be properly kept and pay attention to rust prevention.
Product features: strong structure, flat surface, with good corrosion resistance, oxidation resistance. The material of small hexagonal mesh is the same as that of other hexagonal mesh, which is generally made of low carbon steel wire, stainless steel wire and galvanized steel wire as raw materials by the hexagonal mesh machine.
During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.
The duration of the protective effect of galvanized layer on large roll galvanized wire is closely related to the coating thickness. Generally speaking, in the dry main gas and indoor use, the thickness of galvanized layer only 6-12μm, and in the environment is more severe conditions, galvanized layer thickness needs 20μm “to be up to 50μm”. Therefore, the influence of environment should be considered when choosing the thickness of galvanized layer.
Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.
Galvanized wire coating is galvanized, aluminum plated, coated with nylon or plastic, etc. Zinc is divided into thin coating of steel wire after plating and thick coating of galvanized steel wire after drawing. The mechanical properties of thick coating are reduced compared with smooth steel wire rope, which should be used in severe corrosion environment. It is more resistant to corrosion, wear and heat than galvanized wire rope, using the first plating and then drawing method of production. Coated nylon or plastic wire rope is divided into two kinds of coated rope and coated stock after the rope.
Hot wire is made of high quality low carbon steel, high carbon steel, after drawing, hot galvanized processing galvanized wire. Hot dip galvanized wire production process: wire rod – drawing – annealing – drawing – annealing – galvanized. Hot dip galvanized wire has the characteristics of thick coating, strong corrosion resistance and solid coating. And according to the special needs of users, according to the industry standard to provide various specifications of galvanized wire. Hot-dip galvanized wire is of better quality than electrodip galvanized wire. In the production process, hot dip galvanized wire has more than one annealing process, so the corrosion resistance of hot dip galvanized wire is stronger than that of electric galvanized wire.
