Large volume galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 grams/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, silk screen preparation, highway guardrail, product packaging and daily civil and other fields. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire).

First of all, we need to pay attention to the material of the barbed wire, because the galvanized barbed wire itself includes cold plating and hot plating. The properties and prices of the two are obviously different, and it is easy to be confused by a little negligence.

Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, which is characterized by beautiful, lightweight, folding, easy to store. The surface treatment of pet cage is generally: cold galvanized, hot galvanized, spray, dip, chromium plating, nickel plating and other methods.

In order to pack and bundle galvanized wire on the surface of the deposit layer to remove the surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. Small homogeneous particles of large denier present in the tank can stabilize the foam layer. To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the intake of surfactant. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.

Specific requirements for the safety of galvanized wire production: clean up all tools and other objects that hinder production in the galvanized wire production environment. Operators in the pickling process, pay attention to the action should be careful, not careless, into the pickling tank must be handled lightly, to prevent splashing on the body. When adding acid, the acid must be slowly poured into the water. It is forbidden to pour the water into the acid, so as to prevent the acid from splashing out and hurting people. Do not hurt yourself or others.

On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
