Color-coated aluminum coil coatings are divided into: polyester-coated aluminum coil (PE), fluorocarbon-coated aluminum coil (PVDF).
The polyester coating formed by baking and coating the surface of the aluminum plate multiple times can form a firmly attached continuous solid film with protective and decorative properties. It is an anti-UV coating. The polyester resin uses a high-molecular polymer containing ester bonds in the main chain as the monomer, and adds alkyd resin. The ultraviolet 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 attacked 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. Especially suitable for interior decoration and advertising boards.
The uses, advantages and disadvantages of color steel coils
1. Purpose Colored steel coils are made of high-quality hot-dip galvanized sheets or color-coated steel sheets. They have the characteristics of light weight, high strength, anti-corrosion and durability, convenient construction, and beautiful appearance. They are widely used in construction, home furnishing, transportation and other fields. . 1. Construction field Color steel coils are widely used in the construction field, such as industrial plants, warehouses, shopping malls, stadiums, municipal buildings, etc. Color steel coils can be used as roofs, walls, ceilings and other parts of buildings. They not only have a beautiful appearance, but also provide good thermal insulation, sound insulation and waterproof effects. They have a long service life and low cost, so they are very popular.
2. Home Furnishing Field Colored steel coils are also widely used in the home furnishing field, such as house roofs, wall decorations, garages, walls, etc. Color steel coils have the functions of windproof, waterproof, thermal insulation and sound insulation, and can effectively protect the safety of buildings and people's property.
