Poor pretreatment before electroplating; Bath temperature is too low; Poor quality additives or excessive additives and organic impurities can cause poor bonding. The quality of the additive 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 lattice and create stress, causing the coating to blister.
Post time: 21-10-22Different from the general zinc barbed rope, the zinc content of the surface of the high zinc barbed rope is very high, which can reach 6-8 times of the former, so that it has a great advantage in service life. Ordinary products begin to corrosion in three or five years, while the latter takes longer time to change. Stainless steel barbed rope is in the material aspect of protection so durability is also better, these two products are known for long service life, but is high in price.
Annealed wire is a soft iron wire made of low carbon steel cold drawing, heating, constant temperature, heat preservation and other processes. The composition of iron wire varies according to its use. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet rolled into 6.5mm thick steel bar is the wire rod, and then put it into the wire drawing device into a different diameter of the line, and gradually reduce the aperture of the wire tray, cooling, annealing, plating and other processing technology made of various specifications of iron wire.
Post time: 31-03-23- Similar to two materials in the coating part melting together, and coating thickness can reach 100 microns, so high corrosion resistance, salt spray test 96h no problem, equivalent to 10 years under the usual environment; Cold galvanizing is electroplating at room temperature. Although the thickness of the coating can also be controlled, the binding strength and thickness of the coating are relatively low, so the corrosion resistance is poor.
Compared with galvanizing, hot-dip galvanizing has lower production cost and less environmental impact than galvanizing. Because the coating obtained is thicker, hot-dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for steel parts used in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, ocean exploration, metal structure, electric power transmission, shipbuilding and other industries.
- The drawing process of waste product drawing process has a great influence on product function. Generally, large total surface reduction rate (see area reduction rate) and small pass surface reduction rate (about ≤23%) are selected to ensure the tolerance of products. About high strength spring steel wire, the exit temperature of each pass steel wire should be controlled when drawing below 150℃, to prevent the steel wire from changing cracks due to strain aging, which is the main disadvantage of steel wire obsoletion.
Galvanized barbed wire (barbed wire) is made of galvanized barbed wire twisted on the main wire, so as to play a protective and isolation role. Among them twist weave way is divided into single twist weave and double twist weave. Construction methods include direct installation and spiral insertion.
Large roll galvanized wire is the use of low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes, in the use of is more widely. The temperature of large roll galvanized wire for electroplating should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.
Post time: 07-04-23The use of welding network is very wide, but also used in different industries, different places, many times the name is because of the use or use of the name, so the various uses of the welding network, destined to name a variety of different. Can be called row welding net, or zinc plating welding net or galvanized welding net. And then there’s the external insulation wire, just for insulation, usually on the outside of the wall, to reduce heat loss.
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.
- 2, galvanized welding mesh away from acid and alkali corrosion effect of acid and alkali is electric welding mesh. If the electric welding mesh is accidentally stained with acid and alkali, it should be immediately washed with clean water, and then dried with dry cotton cloth.
- Hook mesh from the point of view of weaving quality inspection requirements, hook mesh wire and silk staggered can not loose, the whole piece of hook mesh can not loose deformation. Of course, if the customer special requirements out of the net, showing loose phenomenon can not blame the production side. Whether the mesh meets the specification requirements and the wire diameter meets the wire diameter.
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.
- In fact, although galvanized hook net is a useful material for iron products, but fundamentally speaking, modern hook net through continuous transformation and improvement, even if it seems to be not useful products, also have a role in its use, here we can turn our attention to people abandoned galvanized hook net.
The stainless steel barbed rope is made of stainless steel material after processing. The barbed rope has the characteristics of corrosion resistance and aging resistance. So why is the price of stainless steel barbed rope more expensive than ordinary barbed rope? Where do you want to go?
- 4, galvanized can be used zincate galvanized or chloride galvanized process, should use appropriate additives to meet the requirements of this standard coating.
Hexagonal net structure can be used for slope support, excavation, rock face net mine support form, slope vegetation (green color), railway road isolation block, it can be made into a cage, cushion, used for rivers, flood dam and seawall erosion protection and storage reservoir, river closed cage. Driving and guiding rivers, river flood disaster is a major water and river erosion of destruction, resulting in flooding, resulting in a great deal of loss of property by the amount of soil and water dissipation. Because of this, in dealing with these problems, the application of the habitat grid structure becomes a solution plan, which has the potential to protect the bank forever.
When the large roll galvanized wire galvanizing process coating foaming, first check the bath temperature. If the bath temperature is not low, then strengthen the plating before removing oil, prevent the matrix metal in acid corrosion. If you pay attention to these problems, the foaming phenomenon still exists, it should pay attention to the amount and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, in order to reduce the content of additives, observe whether the foaming phenomenon is improved. If there is still no improvement, it is necessary to check whether the storage period of additives is too long, or whether there are too many impurities in the additives.
Galvanized hexagonal mesh is a kind of galvanized metal wire mesh, the mesh shape is hexagonal.
We must have a certain understanding of the hexagonal network, we are the beautiful appearance of the hexagonal network, hexagonal network is not only very beautiful appearance, in fact, the practical value of survival is very high. To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.
Because the coastline is generally erected for protection, but often because of environmental factors lead to serious corrosion of the barbed rope lost its function. Stainless steel barbed rope is specially set up to prevent corrosion. Stainless steel barbed rope because the environmental requirements are not very high can be very good protection itself will not have a problem to extend the use of life, so that you can ensure safety.
Hook mesh we usually see everywhere, in fact, hook mesh is a kind of fence, like the highway, stadium fence, road fence, etc., have hook mesh. So what are the effects and advantages of the use of hook net?
- Other discarded guardrails can be used as enclosures for cattle, sheep or other domestic animals. It has a good protective effect. Together these robust products do not have a variety of effects on the overall perimeter. It also shows the value of the rich guardrail network in the community, rural cultivation, or cultivation. Although the appearance of barbed wire fence is not safe after abandonment, the protective function will not be affected, so it will not affect the recovery and use.
Post time: 08-05-23- 4, the material requirements of the silk: change wire braid, electric galvanized wire braid, hot galvanized wire braid, first braid after hot plating.
