The coating of color-coated aluminum coils is divided into: polyester-pinahiran aluminyo coils (PE), fluorocarbon pinahiran aluminyo coils (PVDF). Ang polyester coating na nabuo sa pamamagitan ng pagbe bake ng ibabaw ng aluminyo plate para sa maraming beses ay maaaring bumuo ng isang solidly adhered tuluy tuloy Solid films ay may proteksiyon pandekorasyon katangian. Ito ay isang anti UV patong. Ang polyester dagta ay gawa sa isang mataas na molekular na polimer na naglalaman ng mga bono ng ester sa pangunahing kadena, at isang alkyd dagta ang idinagdag. Ang ultraviolet absorber ay maaaring hatiin sa matt at mataas na gloss series ayon sa gloss. It can endow colorful aluminum products with rich colors, 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 be 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. Lalo na angkop para sa panloob na dekorasyon at mga board ng advertising.
Fluorocarbon Coated Prepainted Aluminum Coil (PVDF)
Fluorocarbon coatings are PVDF resins, mainly referring 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 bonded by fluorine/carbon bonds. The stability and firmness of this chemical structure make the physical properties of fluorocarbon coatings different from ordinary coatings. In addition to the abrasion resistance and impact resistance in terms of mechanical properties, it has excellent performance, especially in harsh climates and environments, it shows long-term fading resistance and UV resistance. After high-temperature baking to form a film, the molecular structure of the coating is tight and has weather resistance.
Fluorocarbon coatings ay maaaring nahahati sa tradisyonal na fluorocarbon coatings at nano fluorocarbon coatings ayon sa ibabaw film formation istraktura. . Coating manufacturers guarantee the service life of coatings starting from 10 mga taon, 15 years to more than 20 mga taon. General coatings have been tested and compared. The coated samples were exposed to hot sunlight in Florida, USA, and exposed to the harsh environment of humid and salty air for 12 mga taon, which actually proved the stability and durability of fluorocarbon coatings. The performance is 30 at 80 percent higher than the other two coatings, and the fluorocarbon coating ensures the use in various harsh environments.
