  • The anticorrosion of these raw materials is very different, and the use of life is not the same. Niu LAN net cold galvanized, also known as electroplating, galvanized quantity is very little, rust in rain, but the price is cheap, the use of life in 5-6 years. Hot dip galvanizing (low zinc and high zinc) on the amount of zinc in 60 grams to 400 grams, the service life is about 20-60 years, corrosion resistance is general.

  • Thus, when zinc is sufficient in a solid melt, the two atoms of zinc and iron disperse with each other. The zinc atoms in the iron matrix are moved into the lattice of the matrix, and the iron elements are gradually formed into alloys. The zinc composition of iron and intermetallic compound FeZn13 in molten zinc solution and the bottom of hot galvanized sheet can be used as zinc slag. The pure zinc layer composed of zinc leaching solution is hexagonal crystal.

  • Large roll galvanized wire is the use of low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes, in the use of is more widely. The temperature of large roll galvanized wire for electroplating should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.
