In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.

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.

The spray blade has strong adhesion and mechanical strength, and is widely used in the isolation and protection of the boundary of grassland and railway, as well as the protection of garden apartments, units and prisons. The following Haorong for you to introduce the characteristics of spray blade rope.

On the highway, barbed rope protection net is generally to prevent people and animals from crossing the highway at will, so as not to interfere with driving and reduce accidents, as well as effectively prevent illegal occupation of road land and other issues of traffic safety facilities. There are many forms of barbed rope protective nets, commonly used metal, woven net, barbed wire and often green gracilaria. Metal braided net is set in crowded areas, barbed wire is used in areas with few people and animals, and the structure of hedges and barbed wire is used in toll stations and service areas. In the past two years, considering the beauty of the problem, in the Pearl River Delta region of some highways with fruit plastic spot welding network (usually said guardrail network), this barbed rope protection network is more good-looking, durable, the overall effect is good, but the construction requirements are higher, more expensive. General sections should not be used, in the city center, scenic spots or strong requirements for beautiful sections can be used.

If the coating roughness is not caused by the above reasons, it may be caused by impurities in the plating solution. Can take a small amount of electroplating solution, after filtration test, then take a small amount of electroplating solution, after zinc powder treatment test, check the problem is caused by solid particles or copper, lead and other foreign metal impurities. Test them one by one and it’s not hard to find the cause of the problem. Galvanized iron wire coating foaming, binding force is not good.

Galvanized silk hook mesh is widely used in warehouses, east and west refrigeration, protective reinforcement, park, zoo fence, Marine fishing fence and construction site fence, machinery and equipment protection. There are two kinds of use, that is, slope protection hook net (slope protection net), coal mine hook net (mine hook net, coal mine support net, roadway support net).

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.
