- After passivation treatment of galvanized layer, it can generate a layer of bright old and beautiful color passivation film, which can significantly improve its protective performance. There are many kinds of galvanized solution, according to its properties can be divided into cyanide bath and cyanide bath two categories. Cyanide zinc plating solution has good dispersion ability and coverage ability, the coating crystal is smooth and meticulous, simple operation, wide application range, in the production is used for a long time.

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.

Replace the column that corroded or misinterpreted and so on resulting in the loss of effect, place the replacement area together from the beginning, and reinforce the column with unstable pile foundation in time. The second is about the protection of galvanized barbed rope itself, to repair the damaged local, will be severely replaced by rust.

When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire.
- 3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag
- Hot dip galvanized steel wire surface smooth, smooth, no cracks, joints, thorns, scars and corrosion, galvanized layer uniform, strong adhesion, corrosion resistance lasting, toughness and elasticity is excellent. The tensile strength should be between 900Mpa-2200Mpa (wire diameter Φ0.2mm-Φ4.4mm). The number of torsion (Φ0.5mm) in more than 20 times, repeated bending should be more than 13 times. The thickness of galvanizing is thin, usually only 3-15 microns, bright, smooth, beautiful appearance, poor corrosion resistance, generally a few months will rust.
- The above is xiaobian for you to introduce the anticorrosion ability of the better barbed rope. You can choose the right barbed rope products according to your actual situation.

With the opening of metro in large and medium-sized cities, as well as the vigorous promotion of subway service in network tools, those who have been accustomed to the subway as a daily means of transportation and urban traffic. These citizens, who love the subway, rely on it and enjoy its speed, often like to call themselves the U-pin price. Is widely used in industry, agriculture, farming, construction, transportation and other welded wire mesh is used in the field of high quality low carbon wire line of welding and become, then after cold, hot dip plating, PVC plastic coated surface passivation, such as plasticizing processing, production of metal mesh with smooth surface, uniform mesh, solder joint is firm, stability, corrosion resistance, good corrosion resistance characteristics.
- Widely used in mining, petroleum, chemical industry, construction, mechanical accessories, protective net, packaging net, barbecue net, barbecue oven net, sintering furnace net, hardware products with net, hardware products with net, arts and crafts with net, vibrating screen net, net basket, food machinery with net, barbecue with net, wall net, grain with net, highway, railway, infrastructure with net.

The wire used for barbed wire is woven or welded with low carbon steel wire, medium carbon steel wire, high carbon steel wire, stainless steel wire and other materials. The production process includes: general braid, embossed braid and spot welding. If the material is steel wire, after equipment processing into a network, it is called wire mesh.

Industrial rust prevention method: coated with asphalt, iron roof, coated with asphalt, you can prevent rust. Metal coating: Some metal surface will form a dense oxide film, can be coated on the surface of the metal composed of this metal screen. Such as: galvanized iron, tinplate plating, bicycle underwire and some medical equipment are coated with chromium and nickel.

Abandoned barbed wire guardrail network will generally choose classification pick up, classification gathering pick up and other methods, better to promote the better use of the whole highway guardrail network, abandoned metal guardrail network is still common copper mesh profile.

When buying large galvanized wire, first look at the hardness of galvanized wire, only after the hardness reaches the standard can be used. The hardness standard of large coil galvanized wire is a very important performance index and an economical test method. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad.
-
The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.

3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag

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.
- (4) Stop the use of more than two strands of galvanized iron wire around the operation method.
