Large 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.
There is as far as possible not to show the trace of the application of wire, wire wound flower stems should be wrapped with green or brown tape, in order to cover the trace of the use of wire, in the use of wire modeling can make the drooping flower head raised, and the flower head reinforcement, for herbs and other flower material soft plants, can make the stalk straight. Wire shearing method: if you want to cut the wire, the wire should be straightened and then cut, can not bend the wire, fold and then cut, otherwise, the wire cut is not straight, will bring a small hook, affect the use.
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.
Annealing wire is widely used because it has a good elasticity and flexibility, in the annealing process can be good control of its hardness, it is mainly made of iron wire, more often used in the construction industry binding wire use. In the production of the wire factory, annealing wire will be processed according to the properties of the material, according to the needs of different to change its hardness degree, can make it has more advantages, can reduce the consumption of metal, reduce the cost of production.
Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.
With other coatings, the opposite is true. Rust builds up immediately and spreads quickly underneath the coating, causing it to peel. The depletion of zinc in the atmosphere is very slow, about 1/17 to 1/18 of the corrosion rate of steel, and is predictable. Its life span far exceeds that of any other coating. The life of the coating depends on the thickness of the coating in a particular environment. And the coating thickness is determined by the thickness of the steel, that is, the thicker the steel is easy to get thicker coating, so the thick steel part of the same steel structure must also get thicker coating, in order to ensure a longer life.
Coping methods we also have: 1, gouging, the straight wire rolled into a wavy shape, but still not enough to raise chickens with mesh can only be large enough to extend the beak can not feed! 2, is the electric welding net, with the current to wire spot welding together, mesh is not limited.
Hexagonal mesh is based on wire mesh prepared by metal wire, wire diameter of 0.3-2.0mm metal wire. Hexagonal mesh is a good choice for breeding cage, he is through hot dip galvanized or PVC coated plastic disposal, the structure is tightly combined with no bump and convex appearance. Keep chickens and ducks, isolate chicken and duck houses, and try to take care of poultry.
Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
They are good at expressing unspoken feelings to people. Their owners feel respect, dependence, admiration and affection. The process of caring for pets inspires people’s sense of responsibility, brings more meaning to people’s life, and helps people establish the fulcrum of life and confidence in life. In fact, dogs are very malleable animals. Through scientific and rational training, you can become a popular family member.
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.
