1. Zinc pot operators must stick to their posts

There is also a scaly or boride film or oxide. To remove the photosynovium or oxide commonly used methods are: lead grease removal method, acoustic cleaning method, alkali washing or pickling electrolysis grease to oxide method, these methods in the use of gas or steam harmful to human body, pollution, not environmental protection.

Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire, the use of low carbon steel wire processing, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Galvanized iron wire can be cut off the tie wire used in the building, the length of 20cm 30cm 40cm, can be cut off according to requirements.

3) wire surface coating: some businesses say their pet cage with what stainless steel, in fact, we also know that the price of stainless steel will not be very cheap, most of the cage surface coating is a layer of anti-rust coating, the material is mainly PE powder, but some color is different. The cage of good quality will be cleaned before coated with PE powder, and then baked at a high temperature of 200 degrees, so that PE powder can stick firmly on the wire.

The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.
