The other is to consider the inner plate of color coated steel plate (double-layer composite steel plate) or back paint (single-layer plate). What should be explained here is that the roof inner panel is more likely to corrode than the wall inner panel.
If the workers can work in this environment, it is possible to use color coated steel plate. But the quality of indoor environment or the investment of environmental protection devices will directly affect the service life of color coated steel plate.
A few years ago, Baosteel had two end users in Guangxi, both producing electrolytic aluminum. However, the service life of the color coated steel plate is very different. One company has been in operation for one year and the color coated steel plate
has been worn out, and the other is still in use for more than 6 years.
(1) Nonferrous metal smelter
Nonferrous metal smelters (copper, zinc, aluminum, lead, etc.) are the most challenging service life of color coated steel plates. However, reasonable selection of materials, design, and environmental protection investment
can ensure or improve the service life of color coated steel plate. 10 years of replacement or maintenance should be possible.
(2) A steel plant, power plant, etc
Corrosive media can also be produced in iron and steel plants and power plants,
but color coated steel plates have long-term use experience.
(3) Machinery manufacturing industry
The mechanical manufacturing industry (automobile, steam turbine, machine tool, etc.) basically will not have a negative impact on the color
coating corrosion, but it should be noted that these industries may have heat treatment furnaces, boilers, etc., which will also affect the local environment. If not handled properly, the color coated steel plate will be corroded, especially at the processing
damage or cutting edge.
(4) Warehousing logistics
This industry is developing rapidly, and light steel is used most. It does not corrode the color coated steel plate. It mainly considers the influence of the environment on the selection of
color coated steel plate. Generally, such projects are concentrated in the industrial environment and coastal areas where the industry is developed and the traffic is busy
(5) Public and civil buildings.
Beauty and durability are the primary
factors to be considered. Therefore, it is very important for the coating to resist discoloration and powdering and to make the coating surface complete and fine. Public and civil buildings pay attention to many people, and close to each other. Therefore,
PVDF or HDP is generally used for coating selection, and light color is often selected.
