Use in daily life does not need to carry out maintenance and maintenance, save a lot of time, but also save maintenance and maintenance costs. The annealed wire has good stability and corrosion resistance, which greatly prolongs its service life. There are many kinds, which can be selected according to different uses. The device for making anneal wire is simple, which improves the utilization rate of the device. The material properties of annealed wire can meet different processing requirements.
In reinforced concrete structure, the crack width of cold wire drawing is smaller than that of circular steel bar or even that of hot rolled thread bar. So cold wire drawing is more popular in the construction industry. The material for cold drawing is made of steel bars and can be simply explained how it is made, that is, its production process is simple. It’s based on steel bars, which are constantly stretched evenly, stretching the bars into something very thin, like wire drawing, without plasticity.
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.

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.
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.
- 2, pasture installation of thorn rope spacing, if it is cattle or horses due to the larger size, the spacing can be appropriately relaxed. But if it’s a sheep, it’s a smaller animal and you have to make it a little bit narrower.
- 2. The cleaning agent used for cleaning should have no effect on the binding force of the coating and no corrosion on the matrix.
- The material of the electric welding net is black wire, galvanized wire and wire drawing. The mesh is 1 inch, 2/1 inch, 3/1 inch, 4/1 inch, 4/3 inch, 8/5 inch, etc. Different materials, different mesh, used in different places. Therefore, electric welding net is an indispensable building material in the construction industry.
- Galvanized iron wire is divided into hot-dip galvanized wire and cold galvanized wire, using low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, hot-dip galvanized, cooling and other processes. With good toughness and elasticity, the amount of zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Galvanized iron wire can cut off the tie wire used in the building, the length is 20cm 30cm 40cm, can be cut off according to the requirements.

Post time: 19-04-23Stainless steel barbed rope according to the different categories of nickel applications are not the same, in the dry indoor environment using 304 stainless steel effect is quite good. However, in both rural and urban areas, to maintain its appearance outdoors, it is necessary to stop washing frequently. In heavily polluted industrial areas and coastal areas, the surface will be so dirty that it will rust. But to achieve aesthetic effect in outdoor environment, it is necessary to use nickel stainless steel. Therefore, 304 stainless steel is commonly used for curtain wall, side wall, roof and other building uses, but in the corrosive industrial or Marine atmosphere, it is best to use 316 stainless steel.
Post time: 12-04-23The external environment has a great influence on the storage of cold drawn wire. Especially during the rainy season, special attention should be paid to the air humidity of workshops and warehouses. It is recommended to use moisture test paper with a value between 8 and 10. If the PH value is high, attention should be paid to the corrosion of the internal cold drawing wire. Cold drawing wire in normal environment storage for two years no problem, cold drawing wire will not be corroded. However, it is necessary to place the coil gently during the handling process to avoid the winding position leading to the cable is not smooth.
Galvanized electric welding net is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machinery and equipment protective cover, animal guardrail, pot flower guardrail, window fence, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration. It is suitable for general engineering building wall, pouring concrete, multi-storey building, etc., which plays an important structural role in the thermal insulation system. In the construction of the building, the thermal insulation board of hot-dip galvanized electric welding grid is placed on the inside of the outer mold of the wall to be concreted. The external thermal insulation board and the wall are one kind of live, and the thermal insulation board and the wall are integrated into one body after the removal of the mold.
6, passivation to remove hydrogen parts should be passivation after the removal of hydrogen, passivation before the application of 1%H2SO4 or 1% hydrochloric acid activation 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
The main raw materials of blade barbed wire are galvanized wire and galvanized sheet. Because the price of galvanized sheet is more expensive than galvanized wire, it is directly reflected in the price of blade barbed wire. There is also the difference in processing technology also leads to the difference in the price of the blade. The traditional barbed rope is made of mechanical wringing, which has a relatively small amount of labor and high production efficiency. However, the blade barbed rope is processed manually after secondary mechanical processing. So whether from the labor force or from the production efficiency also said that there is a large gap. These factors lead to the price of the blade barbed rope is more expensive.
