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 home appliance class color steel material process is fine, the production requirements are high. Thickness of substrate and web coating, better color steel plate substrate is 0.02~0.05mm, lamination or coating thickness is often only 0.15mm below.

Because from the point of view of affecting the use time of color steel plate, the thickness of the substrate is very important. When we compare the quality of color steel plate, the price is one aspect, but don't pay too much attention to the price. If the price of one kind of color steel plate don't other much lower, then we have to pay attention. The use of electrolysis equipment will be fittings after degreasing, pickling, after the composition of zinc salt solution, and connect the negative pole of electrolysis equipment.

The zinc plate is placed on the opposite side of the fittings and connected to the positive pole of the electrolysis equipment to turn on the power supply, and a layer of zinc is deposited on the fittings by using the directional movement of the current from the positive pole to the negative pole, and the cold-plated fittings are processed first and then galvanized. Due to the ammonia triacetic acid on the zinc complexing ability is strong, significantly increase the cathodic polarization of zinc deposition, the plating solution of the dispersion ability and the ability to cover the better, the plating layer is brighter.

After pickling to remove the oxide skin for cold continuous rolling, the finished product is rolled hard coil, due to continuous cold deformation caused by cold hardening of rolled hard coil strength, hardness rise, toughness and plasticity indicators decline, so the stamping performance will deteriorate, can only be used for simple deformation of the parts. Rolled hard coil can be used as raw materials for hot-dip galvanizing plant, the cold formability of thick plate and the yield strength and elongation of the material has a direct relationship. The lower the yield strength value, the smaller the stress required to produce deformation; the higher the value of elongation, high ductility can be allowed to withstand large deformation without fracture.
