The thickness of the color steel coil is very important

Color steel coil materials are divided into five categories: packaging, home appliances, building materials, optical materials and decorative materials. Among them, the color steel materials for home appliances have fine craftsmanship and high production requirements. The thickness of the substrate and peritoneal coating, the better color steel plate substrate is 0.02~ 0.05mm, and the thickness of the coating or coating is often only 0.15mm.

Because the thickness of the substrate is very important in terms of affecting the use time of the color steel plate. When we compare the quality of the color steel plate, the price is one aspect, but we should not pay too much attention to the price. If the price of one color steel plate is much lower than the other, then we should pay attention. Use electrolysis equipment to remove oil, pickle, and put the pipe into a solution composed of zinc salts, and connect the negative electrode of the electrolysis equipment.

Place a zinc plate on the opposite side of the pipe fittings, connect it to the positive electrode of the electrolysis equipment to turn on the power supply, and use the directional movement of the current from the positive electrode to the negative electrode to deposit a layer of zinc on the pipe fittings. Cold plating pipe fittings are processed first and then galvanized. Due to the strong complexation ability of ammonia triacetic acid to zinc, the cathodic polarization effect during zinc deposition is significantly increased, the dispersion and coverage ability of the plating solution are better, and the coating is brighter.

After the oxide scale is removed by pickling, cold continuous rolling is carried out. The finished product is rolled hard coil. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of rolled hard coil increase, and the ductility and plastic index decrease, so the stamping performance will deteriorate, and it can only be used for simple deformation parts. Rolled hard coil can be used as raw material for hot-dip galvanizing plants, and the cold formability of thick plate is directly related to the yield strength and elongation of the material. The lower the yield strength value, the smaller the stress required to produce deformation; the higher the elongation value, the higher the ductility can allow to withstand a large amount of deformation without breaking.
