There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
- Packing and binding galvanized wire is in the liquid state of zinc, after a messy physical and chemical effect, not only on the steel plated thick pure zinc layer, and also generate a zinc-iron alloy layer. This kind of plating method, not only has the corrosion characteristics of the electric galvanized wire, and because of a zinc alloy layer. It also has strong corrosion resistance that can not be compared with electric galvanizing. Therefore, this plating method is particularly suitable for a variety of strong acid, alkali fog and other strong corrosive environment.
2. The cleaning agent used for cleaning should have no effect on the binding force of the coating and no corrosion on the matrix.
- Galvanized iron wire has excellent endurance and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, silk screen preparation, highway guardrail, commodity packaging and ordinary civilian categories.
- The strength, service life and hardness of positive and negative twisting rope are good. The tensile strength of steel wire is 1200N and that of iron wire is 350N. This service life is much longer than ordinary wire barbed rope.
The large roll of galvanized wire is like the literal meaning, is wrapped in a layer of zinc on the surface of low carbon steel wire material, beautify the appearance at the same time, but also improve the corrosion resistance of galvanized wire. Zinc dissolves easily in acids and also in bases, so it is called a bi-soluble metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc.
Compared with the traditional braided and twisted barbed rope, the price of raw materials is relatively high because of the relatively complex technology.
- In addition, galvanized can also improve the beauty and decoration of the product. The surface of galvanized products has a silver-white luster, with better silver light reflection performance, in some cases that need to be decorated beautifully, galvanized products are usually more attractive than non-galvanized products. In addition, due to the existence of galvanized film, the surface of the product is not easy to be eroded by external oxygen, water and other substances, and can maintain the finish and beauty for a longer time.
Some customers may not use the blade rope immediately when they buy it, some are retail, and some are temporarily not used in site construction. At this time, it is necessary for customers to follow up the characteristics of the blade rope for storage. Because they are afraid of rain, so this is needless to say, and the surface of the packaging is more afraid of the sun, so it is not recommended to prevent outdoor exposure to sunlight will cause the woven bag to become ineffective, resulting in the internal blade of the rope exposed to affect the later use.
Nemesis roller cage is used for the isolation and protection of pasture distance, railway and highway, as well as the enclosure and protection of garden apartment, government units, guard posts and border defense. The Nestor rolling cage is fixed with Nestor connecting card at intervals of 120° after the blade barbed rope is wound around the cage. After opening, the Nestor connecting card is formed into a snake belly network. After closing, the diameter of the blade barbed rope ring is 50cm.
- The steel mesh improves shock resistance and crack resistance. The longitudinal and transverse steel bars of the welded steel mesh constitute a network structure. Therefore, the bond anchorage between the steel mesh and concrete is good, and the load distribution is uniform, which significantly improves the earthquake resistance and crack resistance of the reinforced concrete structure. According to the practice test, the cracks of welding net are reduced by more than 75% than that of manual binding net. Greatly reduce the unnecessary cost of the construction process, shorten the construction cycle, the use of steel wire mesh is simple and convenient, easy to transport.
Hardness is a commonly used property index in mechanical properties of metal materials. The iron wire factory introduces a fast and economical test method for hardness testing. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad. In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting.
Hot dip galvanized hexagonal net is made of low carbon steel wire by mechanized braided welding and then by hot dip zinc treatment. The net color is white and shiny, thick zinc layer, uniform mesh, flat mesh surface, solder joint tension resistance, high corrosion resistance. The surface of the steel wire is usually protected by hot-dip galvanizing, and the thickness of the galvanized protective layer can be made according to the requirements of customers. Hot-dip galvanizing hexagonal net is another kind of twisting mesh corresponding to the galvanizing hexagonal net.
Post time: 06-04-23They are good at expressing unspoken feelings to people. Their owners feel respect, dependence, admiration and affection. The process of caring for pets inspires people’s sense of responsibility, brings more meaning to people’s life, and helps people establish the fulcrum of life and confidence in life. In fact, dogs are very malleable animals. Through scientific and rational training, you can become a popular family member.
- Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.

- The drawing process of the waste product has a great influence on the function of the product. The general selection of about 90% of the larger total surface reduction rate (see area reduction rate) and the smaller pass surface reduction rate (about 23%), to ensure the endurance of the product. On the high strength spring steel wire, pulling should be controlled each time the temperature of the steel wire outlet is lower than 150℃, to prevent the steel wire due to strain aging and change the crack, which is the main drawback of steel wire waste.

It can also be used for special mesh of floor heating in construction industry.
Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it is also necessary to conduct reasonable post-processing to avoid affecting its use effect. Of course, when the black iron wire is galvanized, it is also necessary to ensure the thickness of the galvanized layer, so that it can also reduce the possibility of rust. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.
- Whether the wire rope is chosen correctly or not directly affects the service life of the rope and causes the structural deformation, fracture and unexpected failure of the rope. Therefore, the selection principle is as follows: when the progress of unguided heavy objects is made once or repeatedly at a larger height, the non-rotating wire rope is selected:
Cold galvanized, generally speaking, do not need heating, galvanized amount is little, this galvanized parts are easy to fall off in wet environment. Hot dip galvanizing, also known as hot dip galvanizing, is to melt the zinc ingot at high temperature, put some auxiliary materials in, and then dip the metal structural parts into the galvanized groove, so that the metal members are attached to a layer of zinc layer. The advantage of hot dip galvanized is that its anticorrosion ability is strong, the adhesion and hardness of galvanized layer is better.
