There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time. However, because the plating solution contains highly toxic cyanide, the gas escaping in the plating process is harmful to the health of workers, and the waste water must be treated strictly before discharge.

In fact, iron wire has been widely used in our daily life, and it has very good performance. Iron wire production developed earlier because of its simple technology and wide application. Plastic spraying refers to the plastic powder, sprayed on the product of a surface treatment method. Plastic spraying is often referred to as electrostatic powder spraying, the use of electrostatic generator to make plastic powder charged, adsorbed on the surface of the iron plate, and then after 180 ~ 220℃ baking, so that the powder melt and adhere to the metal surface, plastic spraying products are used for indoor use of the box, paint film showing flat or matte effect.
