After the introduction of color coated steel in the United States in 1936, it was first applied to movable shutters, rain barriers and so on. The production process has been improved from the initial one coating and one baking to two coating and two baking or three coating and three baking, and the color coated steel sheets are widely used in construction, automobile, container, instrument shells, etc.
Color coated plate and aluminized zinc plate are very new environmental protection products, representing the future direction of the development of new green environmental protection materials, as the consensus of mankind, reducing carbon emissions and protecting the earth is a new issue we are facing together at present and even in the future, let's work together!
The use of color coated steel plate in different industries is analyzed in two aspects, one is the outer plate of color coated steel sheet, under normal circumstances on the choice of different areas on the line, but also to consider the impact of the small environment. That is, whether there is a corrosive medium falling on the plant enclosure in the vicinity, such as the gas emitted from the boiler, sulfur dioxide dust, etc. This should be considered in the design of the height of the chimney and the main local wind direction, etc.
Non-ferrous metal smelter (copper, zinc, aluminum, lead, etc.) is the most challenging color coated steel plate use life. However, reasonable choice of materials, design, and environmental protection input can ensure or improve the service life of color coated steel sheets 10 years for replacement or maintenance should be able to do.
Mechanical manufacturing industry (automobile, steam turbine, machine tool, etc.) basically will not bring negative impact on color coated corrosion, but it should be noted that these industries may have heat treatment furnace, boiler, etc. will also affect the local environment, and poor handling will bring corrosion of color coated steel coil, especially at the processing damage or cutting edge.
The primary consideration for civil construction is beautiful and durable. Therefore, it is quite important for the coating to resist discoloration and chalking as well as the integrity and delicacy of the coating surface. Public and civil buildings are concerned about many people and close, therefore, the choice of coating generally adopts PVDF or HDP, and mostly chooses light color.
