There are too many fake things on the market now, so shoppers should learn how to distinguish the quality of galvanized wire, the right to protect their consumers’ rights and interests. Galvanizing process of galvanized wire products is a very effective metal anticorrosion method, and it is also widely used in other industrial fields. After galvanizing, iron wire is commonly used in metal structure equipment of various industries.
Post time: 10-04-23Wire factory introduction annealing wire is widely used mainly because it has good elasticity and flexibility, in the process of annealing can be very good control of its soft and hard degree, it is mainly made of iron wire, more often used in the construction industry tied wire use. In the production of annealing wire will be processed according to the performance of the material, according to the demand for different degree of hardness of its soft change, can make it has more advantages, can reduce the consumption of metal, reduce the cost of production.
Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.
The anticorrosion of these raw materials are very different, the use of life is not the same. Cattle fence cold galvanized, also known as electroplating, galvanized little, rust in rain, but the price is cheap, the use of life in 5-6 years. Hot dip galvanizing (low zinc and high zinc) zinc content in 60 grams to 400 grams, the use of life is about 20-60 years, corrosion resistance is general.
Some customers pay more attention to the quality problem, so they pay more attention to the service life. The barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.
Wire mesh welding after galvanized is through the end of the welding and then the cold company to make wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot galvanized. After the first galvanized welding is to change the wire mesh, after the end of welding can see the welding spot; The two processes are different prices are also very different, the cost of the first plating after welding is low, the appearance is smooth, and the cost of the first welding after plating is higher, not easy to rust.
Hot-dip galvanized wire has longer service life and better corrosion resistance than ordinary steel wire. Hot dip galvanizing is a method of chemical combination of zinc metal and steel wire surface, through the formation of a strong and self-healing zinc-iron alloy protective layer on the steel wire surface, so as to prevent direct contact between the steel wire and the external environment, reduce the possibility of oxidation corrosion, and extend the service life of the steel wire.
Hexagonal guardrail net custom corrosion lost the original characteristics, in the shape, color and mechanical properties will change, resulting in equipment damage, pipeline leakage, etc., specifically, is prone to fracture, 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 than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail net and extend the service life of the product.

Post time: 11-05-23In use, there is no need for daily maintenance and maintenance, not only can save a lot of time, but also can reduce costs, but also has good stability, strong corrosion resistance, greatly prolong the service life. According to the different process is divided into different types, can choose according to their own needs. With good flexibility and elasticity, the main role of annealing wire is to control its degree of softness and hardness, in the production of annealing wire is made of steel wire, now more used in the construction industry binding use, compared with ordinary wire is also more soft, have better luster.
- For key and important parts with tensile strength greater than 1034Mpa, the stress should be removed at 200±10℃ for more than 1 hour before plating, and for carburized or surface hardened parts, the stress should be removed at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.
The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.
In the calculation process of 12*14 specifications of barbed rope, it can not be calculated according to the above calculation formula, because first of all, two specifications of raw materials are used, the thinner the wire diameter, the higher the processing cost. Generally speaking, a kilogram of 12*14 barbed rope can reach about 7.5 meters, and the ratio of warp wire to barbed rope cannot be calculated according to the traditional ratio of 7 to 3. The specific use of how much wire and silk need to go through a series of professional measurement but also increase the loss of raw materials and other factors to calculate. Thorn rope factory will also according to customer needs to calculate the reasonable amount of customer use.
- 3. Before cleaning the cage, put the birds in a safe place, and then clean out the garbage inside the cage. Clean it up with a sweep. Then use a wet rag to clean on site.
With the improvement of living standards and the reduction of family size, keeping pets is becoming a way of life for many people. According to statistics, the number of pet dogs has reached more than 100 million, and the trend is increasing rapidly every year. Beijing alone had more than 900,000 licensed dogs in 2010, according to a survey, and the number of pet cats is also very large.
Pay attention to safety in line collection and operation, others without the consent of the monitor, Ben have to get on the bus operation. The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.
- Because of the beauty, art, or in specific severe corrosion environment, galvanized layer can be applied to the above paint duplex system, as long as the paint system selection is correct, easy construction, its anticorrosion effect is 1.5~2.5 times better than the single paint and hot dip zinc life combined. With zinc layer to protect iron and steel, in addition to hot dip galvanizing method, there are several other methods, generally widely used, corrosion prevention effect is good and good economic benefits, hot dip galvanizing method.
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.
- 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:
