Cold galvanizing, also called electric galvanizing, is the use of electrolytic equipment to remove oil, pickling, after the pipe fitting into the composition of zinc salt solution, and connected to the negative electrode of the electrolytic equipment. Wire factory on the opposite side of the pipe fittings placed zinc plate, connected to the positive electrode of the electrolytic equipment is connected to the power supply, the use of current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings, cold plating pipe fittings is first processed after galvanized.

The use of electric welding mesh is very wide, can be used in many places. In the field of construction, especially the wall crack, has played a very important role, the traditional construction, is to put on mortar directly onto the wall, after such a long time, will appear fall off and fracture phenomenon, in order to prevent the occurrence of this phenomenon, must use welded wire mesh before rendering, welded wire mesh is fixed to the wall, above the plastering construction, Can ensure that the wall level for a long time, not easy to crack phenomenon.

In order to pack and bind galvanized wire in the surface of the sedimentary layer to local removal of surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. Small, homogeneous particles of large denier present in the bath can stabilize the foam layer. Use activated carbon mat to remove surface active substance. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to reduce the amount of surfactant introduced. The electroplating speed can be obviously reduced by the addition of organic matter. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.

4. Keep the rinsing water clean after wire pickling, which is an important link to reduce zinc consumption. The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate.

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.

Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve.

As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:

Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.
