  • The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.

  • Unless the stainless steel blade barbed rope is specially customized, it is usually produced by the mould with the knife length of 22mm, which is the BTO-22 type we usually call. This is not necessarily the specification from 11mm to 65mm are specifications. Unless the customer insists on customized length requirements, the barbed rope manufacturer will produce BTO-22 stainless steel blade barbed rope.

  • When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well. Galvanized wire, also known as hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion.

  • When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.
