Application industry: chemical workshop, chemical tank insulation and anti-corrosion projects.

Industry characteristics: Chemical products have volatile characteristics, and are prone to acidic or alkaline volatile substances. When exposed to water, dewdrops are easily attached to the surface of the color plate, causing corrosion on the coating of the color coated plate. It may be further corroded to the zinc layer or even the steel plate.

Material selection criteria: Considering the special requirements of the chemical industry for anti-corrosion requirements, it is recommended to use PVDF fluorocarbon color plate, constant color anti-fading plate or HDP high weather resistant color plate. The substrate is made of Z275 galvanized sheet or AZ150 galvanized sheet. 20-25 μm. Of course, it is also possible to appropriately lower the standard according to the specific project cost and requirements.
