Of course, the quality of any kind of product is also affected by the implementation of the specification by the manufacturer. If the manufacturer of electric welding mesh has no high implementation specification in the production itself, or the procedure specification has declined in the production line, or there is no higher requirement on the production link.

Heavy hexagonal mesh is made of steel wire by special machinery woven hexagonal mesh mesh. This kind of net, after cutting, assembly can be made into fence net, mountain hanging net, vegetation three-dimensional network, combination and so on.

If the surface of galvanized wire is black and the galvanized layer is thin and uneven, the galvanized wire is partly because the inventory storage time is longer, but also because the production technical requirements of galvanized wire do not meet the standard and lead to the quality problems of galvanized wire. According to the use of galvanized wire is different, galvanized wire has soft and hard, then the galvanized wire used for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, and it can be easy for workers to operate.

To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the amount of surface-active substances brought in to Z. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

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.

This method is generally the use of hot rolled laminated plate as raw material, the annealed steel plate is first sent to the pickling workshop, with sulfuric acid or hydrochloric acid to remove the surface of the steel sheet oxygen hot galvanizing method. After pickling, the steel plate immediately enters the tank to soak and wait for galvanized, which can prevent the reoxidation of the steel plate. After pickling, water cleaning, squeeze dry, drying, into the zinc pot, the temperature has been maintained at 445-465℃.

The insulation layer of large rolls of galvanized wire and rigid thermal insulation products can be bound with double strands of galvanized iron wire, and the binding interval shall not exceed 400mm. The pipe or corresponding equipment with nominal diameter equal to or greater than 600mm shall stop reinforcement after binding, and the enclosed galvanized steel wire must be winched. The iron or wood rod should be tightened, but the tightening level should be moderate, not too tight or too loose, and not damage the wire. The consumption of wire and steel wire is generally used in drawing process and galvanized disposal.

Hook mesh is crocheted with silk heart, its mesh is uniform, flat net surface, beautiful and generous net width, thick silk diameter, not easy to corroded long life, weaving simple, beautiful and useful. Widely used for raising chickens, ducks, geese, rabbits and zoo enclosures. Protection of mechanical equipment, highway guardrail, sports site fence, road beautification with protective net. The screen in the manufacture of a box-like container, with stone filled with the cage, can be used to maintain and support seawall, hillside, road and bridge, reservoir and other civil engineering.
