Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.

We basically know that the barbed wire fence generally has two kinds of ring and linear filamentous, the overall protective wire mesh selection of galvanized, stainless steel processing raw materials, long-term use is not easy to rust. Barbed wire fence uses stainless steel barbed wire, plastic coated barbed wire, aluminum coated barbed wire, galvanized barbed wire and other raw materials through special wire drawing into the strand planning, has a strong role in protection and maintenance. Widely used on both sides of the highway, grassland, gardens and other places, because it is a field protection product and therefore updated faster, so how to use the barbed wire fence after abandonment? Here are some of the uses of discarded blades.

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.

That said, it can always deform by pulling hard without changing its integrity, so cold drawing has usually reached a limit, which is not a problem, because without this property it increases hardness, which is the desired effect. Cold wire drawing encountered more rain, when the climate is wet, easy oxidation and rust. Therefore, in the storage process should pay attention to avoid rust.

Pet cage from the use of material can be divided into plastic, wire, wire square tube, stainless steel four. General small animal cage multi-purpose is plastic and wire material, such as a lot of hamster cage, chinchilla cage are made of plastic or wire, small aquarium is plastic products, and the vast majority of small and medium-sized bird cage are wire products. The characteristics of this kind of small animal cage, is small, light, easy to carry, but also easy to clean care. For small animal cages, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violent”, or the cage under the “destruction” will occur welding or plastic crack off.

2, mesh, mesh also directly affect the price of stone cage net

Due to the influence of production process or other factors, the zinc layer of galvanized wire products will be different to a certain extent, especially ordinary galvanized can not reach the beauty of electric galvanized, ordinary galvanized wire zinc layer is mainly for anticorrosion and corrosion prevention. Large volume galvanized wire products refers to the use of high quality low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes, some galvanized wire products are made of iron wire galvanized.
