Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Hot dip galvanizing is dipped in zinc liquid melted by heating. It has fast production speed, thick but uneven coating. The market thickness is 45g and can reach more than 300g. The color is dark, the zinc metal is consumed, and the matrix metal is formed into the entry layer, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can adhere to decades.
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.
No matter how good the quality of hot-dip galvanized barbed rope is, it is only attached to the surface of the wire with galvanized layer, and with the cause of chemical reaction, the zinc layer on the surface will gradually lose its effect because of oxidation reaction, which is more prominent in the humid area of the environment. And because, after all, the wire will rust, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
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.
Hot dip galvanizing, also known as hot dip galvanizing, is a method of obtaining a metal covering layer by immersing a steel member into a molten zinc solution. With the rapid development of high-voltage power transmission, transportation and communication, the protection requirements for steel parts are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electrogalvanized layer is 5 ~ 15μm, and the large roll galvanized wire layer is generally more than 35μm, or even up to 200μm. Hot dip galvanized coating ability is good, dense coating, no organic inclusions.
Usually according to the general people, the blade barbed rope is the guardrail, widely used in garden apartments, military bases, private residential areas, government machinery where there is a fence, generally used blade barbed rope. The biggest advantage of the blade is that the protective effect is good, and the installation and maintenance is very convenient, strong isolation ability, good resistance effect, etc.
The construction of inner wall and outer wall steel wire mesh can effectively solve the wall cracks, falling off, empty drum phenomenon. Hot dip galvanized steel wire mesh material requirements: net surface leveling, width and length to meet the project required standards, welding process, weight, zinc, etc., with more production and operation, detection certificate is complete.
(2) Packing and binding galvanized shaft wire order notes: ① the galvanized iron wire shall not be damaged when the tightening. (2) Stop the use of more than two strands of galvanized iron wire around the operation method. ③ The diameter of galvanized wire for pulling should not be less than 4mm, and the diameter of galvanized wire for binding should not be less than 2.6mm. (4) Galvanized iron wire shall not be used as waist hoop down reinforcement, usually not used as a whole binding. Warehouse galvanized wire is mainly used to block and distinguish the function of the area, warehouse galvanized wire is one of the primary use of galvanized wire, warehouse galvanized wire primary layout features are as follows: layout: Column mesh frame, column to choose square steel pipe, galvanized wire frame is also a small square pipe as the data, column and mesh frame corresponding direction are welded connecting ear piece (flat iron), column and mesh frame through the connection of the ear piece bolt fixed, column bottom welding plate, column bottom plate through expansion bolts and fixed on the ground.
