What kind of steel coil products are used in sulfuric acid environment?

Product introduction
Color-coated aluminum coil coatings are divided into polyester-coated aluminum coils (PE), and fluorocarbon-coated aluminum coils (PVDF). The polyester coating formed by baking and coating the surface of the aluminum plate multiple times can form a firmly adherent continuous layer. The solid film has protective and decorative properties. It is an anti-UV coating. The polyester resin uses a polymer containing ester bonds in the main chain as a monomer and adds alkyd resin. The UV absorber can be divided into matte and high-gloss series according to the glossiness. It can give color aluminum products rich colors, and has good gloss and smoothness, as well as superior texture and feel, and can also increase the sense of layering and three-dimensionality. It can protect objects exposed to the atmosphere and attack by ultraviolet radiation, wind, rain, frost, and snow; due to temperature differences, freeze-thaw cycles, corrosive gases, and microorganisms, the coating can play a protective role.
Fluorocarbon-coated aluminum coil (PVDF)
Fluorocarbon coatings are coatings made of PVDF resin, which mainly refers to vinylidene fluoride homopolymers or copolymers of vinylidene fluoride and other small amounts of fluorine-containing vinyl monomers. The chemical structure of the hydrofluoric acid base material is combined with fluorine/carbon bonds. This stable and strong chemical structure makes the physical properties of fluorocarbon coatings different from ordinary coatings. In addition to its excellent wear resistance and impact resistance in terms of mechanical properties, it also shows long-term fading resistance and UV resistance in harsh climates and environments. After high-temperature baking to form a film, the molecular structure of the coating is tight and has super weather resistance. Fluorocarbon coatings can be divided into traditional fluorocarbon and nano-fluorocarbon coatings according to the surface film formation structure. Due to the characteristics of the aluminum coil and the characteristics of fluorocarbon paint, this product can be used in a sulfuric acid environment. Most of the customers use it for building roof tiles. It can be guaranteed not to fade for 10 years in the harsh environment of sulfuric acid.
