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. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
Galvanized wire is divided into hot dip galvanized iron wire and galvanized iron wire according to the production process. It has the characteristics of high tensile strength, good softness, zinc layer uniformity, corrosion resistance, beautiful color, good smoothness, strong adhesion and corrosion resistance. Hot dip galvanizing has better protective properties than electric galvanizing, so it is an important protective coating for steel parts used in harsh working conditions.
Solder spot, size and wire diameter of galvanized electric welding net. There are clear regulations about size and diameter of silk, as long as it meets the standard, there will not be too much difference. Galvanized welding net production is mainly welding, welding point is firm directly determine the quality of the net. Large galvanized wire purchase process need to carefully observe the solder joint, if the solder joint is too shallow, it shows that the welding is not so strong, it is easy to open welding after use.
The spring steel wire is made of high carbon and high quality carbon structural steel or carbon tool steel wire rod, and its chemical composition, gas content and non-metallic inclusion must be strictly controlled according to the use of the spring. In order to reduce the appearance of shortcomings and decarbonization layer, the consumption of rod billet to stop surface grinding, if necessary, but also stop peeling.
There are two kinds of use, namely slope protection hook mesh, coal hook mesh, mining hook mesh, coal mine support network, roadway support network. The height of the outer rail of the pavement or seat belt should not be less than 1.10 m. The net distance between balustrade members shall not be greater than 140 mm, and horizontal rail shall not be used. Hook mesh planning is necessary to be safe and reliable, anchor should be installed on the basis of the railings, its strength should meet the requirements of the standard.
Large hexagonal mesh called stone cage net, is mainly used for mountain protection, hydraulic construction and so on. Small wire hexagonal mesh is used as a good material for breeding, will twist twist hexagonal mesh in the welded iron frame on the hexagonal mesh welding into chicken coop, pigeon cage, rabbit cage cage cage, hexagonal mesh is the best material for breeding with a net.
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.
The galvanized layer forms a particular metallurgical structure that is capable of accepting mechanical damage during transport and use. Every part of the plating can be zinc plated, even in dents, sharp corners and hidden places can be fully maintained. The galvanizing process is more convenient than other coating construction methods, and can avoid the required time after the installation on the site.
2, can quickly let the dog develop home habits, let it learn to wait for the owner to take it out, prevent it from making the home dirty, dirty its nest.There is a connection between the hook mesh and the aperture, in short, the general hole small hook mesh, the wire is also very small; Aperture is large, hook mesh wire is generally larger. The weaving of the hook mesh also has certain rules, using the first pre-bent into a wavy wire, and then woven into the hook mesh. According to the knitting method, the hook mesh can be divided into: closed weaving, two-way plain weaving, one-way corrugated weaving, two-way plane weaving, two-way corrugated weaving, rectangular hole weaving.
Wire factory reminds you in the purchase of galvanized wire, should be stored in dry, ventilated conditions, do not contain corrosive gases, do not mix with organic volatile gas produced paint, plastic and other substances in a good environment. If possible, we can add reliable inner packaging for galvanized parts, and put desiccant. If the zinc layer of white spots and long hair, can only be removed by mechanical methods, and then normal passivation, or completely washed off the zinc layer after re-plating.
Traditional barbed wire is woven into wire, with the development of the economy, the rapid rise of all walks of life, the limitations of the use of traditional barbed wire gradually exposed, such as: aquaculture, to the chicken circle a cage can not be too dense, the wire can not be too thick, woven mesh wire once the mesh over the surface of the net will become soft. We also have the solutions: 1, rolling the straight wire into a wavy shape, but still not enough to feed chickens with mesh can only stretch out the chicken beak can not feed! 2, is electric welding mesh, with the current to the longitude and latitude of the wire spot welding together, mesh do more than most is not restricted.
Large roll galvanized wire is made of low carbon steel wire rod processing, is made of low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other surface treatment process processing. Large roll galvanized wire is divided into hot dip galvanized wire and cold galvanized wire (electric galvanized wire). Although galvanized galvanized wire and silver powder paint spray effect appearance is not much different. But the effect is very different, galvanized wire surface is zinc layer, good adhesion, good corrosion resistance.
There are many kinds of zinc plating solution, which can be divided into plating solution and no plating solution according to its properties. The galvanized liquid has good dispersion and covering property, the coating crystal is smooth and fine, the operation is simple, the application range is wide, and the long-term use is in the production. However, due to the toxic substances contained in the plating solution, the gas escaping from the plating process has great harm to the health of workers, and the waste water must be treated strictly before discharge.
