Broken wire is the iron bright wire, fire wire, galvanized wire, plastic coated wire, paint wire and other metal wire, wire factory according to customer requirements for straightening after sizing cut, has the characteristics of easy transportation, easy to use, widely used in the construction industry, handicrafts, daily civilian and other fields. No limit on length, packing as required. Annealing wire also known as black oiled wire, black annealing wire, fire wire, black iron wire. Compared with cold drawing, black annealed wire is more economical as raw material for nails.

Compared with galvanizing, hot-dip galvanizing has lower production cost and less environmental impact than galvanizing. Because the coating obtained is thicker, hot-dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for steel parts used in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, ocean exploration, metal structure, electric power transmission, shipbuilding and other industries.

5, after the light plating should be carried out light treatment.

A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.

Stainless steel barbed wire is mainly used in the place near the sea more, wet salty air for metal corrosion is particularly serious, and the selection of stainless steel barbed wire is in order to prevent corrosion.

Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Solid particles or excessive foreign metal impurities in the electroplating solution can cause such problems. Solution: If the coating of large galvanized wire is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.

A pet carrier can be used as an indoor or outdoor pet house. The dog cage is equipped with a fixed food basin and water fountain, and the foot plate pet cage rubber pad has bayonets on four sides to be splintered. It can be spliced, cut and disassembled according to the size of the cage. It is convenient and easy to clean. It can solve the problem of pinching the feet of the puppies in the ordinary cage and prevent the puppies from causing adverse reactions in the development. The dividers are breathable and comfortable, and can be used as heat shields for pets in summer. A puppy with small feet, no feet, no pinching.

The physical methods mainly include manual rust removal and mechanical rust removal, chemical rust removal is generally the use of pickling method, practical application, usually according to the appearance of the workpiece rust status and different post-treatment process, choose different rust removal methods, among which pickling rust cleaning is more commonly used. That is, the iron and steel workpiece with oxide skin or rust is etched in the acid lotion, mainly to remove the oxide or rust layer on the surface of the steel.
