  • The surface of alluvium before hot dip galvanizing of orchard special electric galvanized shaft wire can partially remove the surface film layer, surface impurity and other shortcomings according to the basic technology to find and solve; Excessive foam is caused by soap and soapable surface active substances such as human fat into the tank. A moderate rate of foam production would be fine. There are many fine homogeneous particles in the tank, can stabilize the foam layer, with activated carbon mat to remove surface active substances. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to reduce the amount of surface-active substances introduced. The introduction of organic matter can make the electroplating process speed drop sharply. Although the secret recipe of organic chemistry is beneficial to the high accumulation rate, the thickness of the coating can not meet the requirements after the organic matter is brought in, so the activated carbon can be used to solve the tank.

  • Galvanized wire is processed from low carbon steel wire rod, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire is widely used. Electroplating temperature should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.
