The instruction and application of PE PVDF coated aluminum co

The color coated aluminum coil roll has the properties of high mechanical strength and easy forming of steel materials, and good decoration and corrosion resistance of coating materials. Color coated coills are widely used in various industries such as architecture, household appliances, automobiles, furniture and light industrial products.

At present, the materials used in the market are cold-rolled substrate, hot-dip galvanized substrate, galvanized substrate, aluminum-zinc substrate and so on. In addition, it is the use of hot-dip galvanized steel strip as the substrate of color coated steel strip, in addition to the protection of the zinc layer, the organic coating on the zinc layer has played a role in covering and protecting, prevent steel strip rust, longer service life than galvanized strip.

Color coated aluminum coil is made of aluminum alloy after processing. Compared with ordinary aluminum coil, it has more advantages in aesthetics and better decorative effect. Color coated aluminum coil can also be divided into many different types.

1. Polyester Coated Aluminum Coil (PE coated aluminum coil): The polyester coating formed by repeated baking on the surface of the aluminum plate can form a solid continuous solid film with protective decorative properties. It is a UV-resistant coating. Polyester resin is a polymer monomer containing ester bond in the main chain, adding alkyd resin. The UV absorber can be divided into Matt and high gloss series according to gloss. It can give colorful aluminum products rich color, and has good gloss and smoothness, as well as superior texture and feel, it can also increase the sense of hierarchy and three-dimensional. Protects objects from exposure to ultraviolet light, wind, rain, frost and ice; coatings protect them. It is especially suitable for interior decoration and advertising boards.

2. Fluorocarbon coated aluminium coil (PVDF coated aluminum coil): Fluorocarbon coatings are PVDF resins, mainly refers to vinylidene fluoride homopolymer or vinylidene fluoride copolymer with other small amounts of vinyl fluoride monomer coatings. Fluorine / carbonization bond is used in the chemical structure of fluorine base material. The stability and firmness of the chemical structure make fluorocarbon coatings different from ordinary coatings. In addition to the mechanical properties of wear resistance, impact resistance has excellent performance, especially in adverse weather and environment shows long-term anti-fading, anti-ultraviolet properties. After high temperature barbecue, the molecular structure of the coating is compact and has super weatherability. Fluorocarbon coatings can be classified into two types: traditional fluorocarbon and nano fluorocarbon coatings. Especially suitable for public places, indoor and outdoor decoration, commercial chain, exhibition advertising and other decoration and display.
