In the process of composite plating, it is necessary to stir the plating solution to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. In the process of production, the acid activation solution can remove the corrosion products and oxide film on the surface of low carbon steel wire without excessive corrosion on the matrix. Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire.

Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.

The advantages of hexagonal net to do jet hanging net, the first is that the processing speed is fast, the cost is low, and it is very good to roll out when it is open because of the edge. Common specifications: 12 cm x15 cm (11cm x11 cm) 11 cm x15 cm (10 cm x10 cm) 10 cm x12 cm (9 cm x9 cm) 9 cm x13 cm (9 cm x9 cm) 8 cm x10 cm (7 cm x7 cm) common wire: 1.3mm 1.4mm 1.5mm 1.6mm 1.7mm 1.8mm 2.0mm 2.3mm 2.5mm Commonly used materials: galvanized wire hot dip galvanized wire to wire drawn zinc aluminum alloy plastic coated wire stainless steel wire.

Welding electrode has a wide range of applications, can realize a variety of materials, a variety of profiles and a variety of joint forms of welding.

Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.

3cm electric welding net refers to the square hole net of 3cm mesh, galvanized net, impregnated plastic wire mesh, metal mesh, screen. Wide 0.914 m, 1.02 m, 1.2 m, 1.5 m, 1.8 m, length of each volume in 18 to 30 m, welded wire mesh is a wire drawing, wire with advanced welding equipment on the line of welding and become, can be cold zinc, hot dipped galvanized after welding, jinsu anticorrosive processing, also can use the black wire or change wire drawing, galvanized wire, stainless steel wire welding forming, The electric welding mesh is firm, the mesh surface is smooth, is widely used in construction, breeding, isolation, handicraft manufacturing, filtration, mechanical protection, animal fencing and other aspects, according to the demand can be customized electric welding mesh coil, can also be cut into electric welding mesh.

After the optimization of the process, mass production of 0.80mm electro galvanized steel wire electro galvanized zinc layer quality is controlled within 80 ~ 90g/m2, zinc layer quality dispersion is very small; The results show that the average weight of zinc layer is 14.5g/m2, the loss of zinc layer is less than 5%, and the tensile strength of steel wire is 2300 ~ 2500MPa. It not only effectively controls the quality of zinc layer of raw steel wire, but also reduces unnecessary waste and production cost.
