On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
In sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in the high temperature and high humidity atmosphere containing organic acid, galvanized wire galvanized layer is easy to be corroded. The uniformity of the galvanized layer on the surface of galvanized wire and the color of galvanized wire, the galvanized layer on the surface of high-quality galvanized wire is uniform, zinc adhesion is good, and the color is white, there is no leakage plating and rust points and other problems.
U nail price is made of high quality stainless steel wire row welding; For example, machine protective cover, animal animal fence, flower fence, window guard bar, channel fence, poultry cage and home office food basket, paper basket and decorative articles, more acid, alkali, welding firm, beautiful and other characteristics.
Plastic coated welding net: PVC plastic coated welding net is a kind of tall appearance of the welding net, plastic coated welding net picture upper protective barbed net, cable for galvanized steel wire, PVC coated plastic treatment, in the protection of beautiful at the same time, to ensure the strong and durable. Material: low carbon steel wire, PVC coated plastic manufacturing process: steel wire welding coated plastic, can also be separate plating, hot plating and coated plastic. PVC coated plastic welding net uses: industrial, agricultural, municipal, transportation and other industries fence, decoration, protection and other facilities.
The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.
The iron wire used for the barbed wire is woven or welded into low carbon steel wire, medium carbon steel wire, high carbon steel wire, stainless steel wire and other materials. Production process: general braided, embossed braided and spot welding. If the material is steel wire, after equipment processing into a network, it is called wire mesh.
