3. Acid activation acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts, without excessive corrosion on the matrix.
4. Keep the rinse water clean after pickling the steel wireLarge roll galvanized wire is made of low carbon steel wire rod processing, is made of low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other surface treatment process processing. Large roll galvanized wire is divided into hot dip galvanized wire and cold galvanized wire (electric galvanized wire). Although galvanized galvanized wire and silver powder paint spray effect appearance is not much different. But the effect is very different, galvanized wire surface is zinc layer, good adhesion, good corrosion resistance.
Six: The characteristics of spray blade barbed rope are mechanical strength, adhesion, corrosion resistance, aging resistance, etc., which will greatly increase the service life of the barbed rope, anti-ultraviolet, anti-aging weathering.Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
Railway is not only the main artery of national economy, but also an important means of mass transportation to protect people’s travel. It plays an important role in the process of economic and social development. Therefore, the safety issue is an important guarantee for railway transportation, one is a symbol of the railway transportation enterprise product quality, the other is also the focus of social attention. The off-road collision accident is one of the focus of public opinion on the railway industry. How to grasp the off-road safety management, eliminate the off-road collision accident from the source, maximize the protection of people’s life and property safety, and reduce the non-operational cost of railway enterprises is a key content of railway safety work in the new era. We should install protective nets on both sides of the railway, which are also barbed wire protective nets, so as to prevent accidents.
Hook mesh wire diameter has thickness, fine wire diameter is generally 0.5mm-2.0mm, thick wire diameter can be in 5mm-22mm. Hook mesh is also customized according to different uses, in general, fine silk can be woven into a relatively small hole, thick silk is generally called heavy hook mesh, mainly used in the screening of stones and coal, in short, hook mesh has an important role in many professions.
Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
The advantage of galvanized iron wire after annealing: after annealing increases the elongation of the iron wire. Makes the product softer and increases the range of application. After electric galvanizing hot dip galvanizing. Copper electroplating is widely used and screen production. Galvanized iron wire is a soft iron wire product processed by low carbon steel wire through cold drawing, heating, constant temperature, and even heat preservation. Generally, the quality of ordinary galvanized iron wire will be relatively soft, the softness is relatively balanced, and the color is consistent. It is mainly used in construction, mining, chemical industry and so on.
3. Zinc layer structure: The structure of zinc layer includes grain size, grain shape and the combination of zinc layer and substrate, etc., which has a certain impact on corrosion resistance. In general, the finer the grain size, the denser the structure, and the better the corrosion resistance.
Large roll galvanized wire is simply galvanized iron wire, usually used wire is often visible, because iron is very easy to be corroded and rusted, so it is necessary to put a layer of other not easy to rust metal plating in the outer layer, to achieve the effect of corrosion resistance and rust resistance, the effect of zinc can do more. Therefore, many customers often require hardware factories to produce galvanized iron wire, which requires the use of galvanized iron wire equipment.
Packing is also very important. The cut wire should be bundled and tightly packed with plastic film, and then placed in a regular box. The whole box should be filled and sealed. It is better not to have half a box.Silk screen material can choose galvanized wire, stainless steel wire, copper wire, plastic coated wire, paint wire, etc., different materials used in different fields, such as construction, breeding, decoration, etc.
