Galvanized iron wire is a substance we often see in life. It is the zinc gradually plated on the metal surface through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, the corrosion resistance is poor, and the corrosion will rust in a few months. Galvanized wire has the characteristics of thick galvanized layer, strong corrosion resistance, strong galvanized layer, etc., the products are widely used in construction, highway walls, Zahua, weaving nets.

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.

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.

Zinc is a silver-white metal, brittle at room temperature, soluble in acid can also be soluble in alkali, known as amphoteric metal. Pure zinc in dry air is more stable, in humid air or containing carbon dioxide and oxygen water is small, the surface will generate a layer of basic zinc carbonate based thin film layer, it can delay the corrosion rate of zinc layer. The corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride is stronger.

It is precisely because of the advantages of electric welding mesh (explanation: can overwhelm the favorable situation of the other side), the electric welding mesh in the market is widely used in urban roads, real estate, development zones, residential areas, gardens and all kinds of enterprises and institutions of decoration beautification and security protection works. Stainless steel wire mesh is one of stainless steel wire mesh products.

Hot dip galvanizing is to remove oil from the workpiece, pickling, dipping, drying after dipping into the dissolved zinc solution for a certain time, can be brought out. Hot dip galvanizing is an effective way to prevent corrosion of metal. It is mainly used for metal structure facilities in various industries. It is to immerse the steel parts after rust removal into the melting zinc liquid at about 500℃, so that the surface of the steel members is attached with zinc layer, so as to play the purpose of anti-corrosion. The galvanized layer is more firm.

2. Adjust the drawing process parameters of the water tank

Different from the general zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach the former 6-8 times, so in the service life also has a great advantage, ordinary products three or five years began to corrosion and the latter will take longer to change. Stainless steel barbed rope is in the material aspect of protection, so the durability is also better, these two products are long in the service life, but in the price is high.

Large roll galvanized wire is processed by low carbon steel wire rod, through drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Large roll galvanized wire electroplating temperature should be controlled in 30-50℃. Because of the strong corrosivity of chloride ions in bath, quartz glass heater is generally used. Continuous production does not need heating, but need cooling cooling.
