The coating of color-coated aluminum coils is divided into: لفائف الألمنيوم المطلية بالبوليستر (PE), لفائف الألمنيوم المطلية بالفلوروكربون (PVDF). يمكن لطلاء البوليستر المتشكل عن طريق تحميص سطح لوح الألمنيوم لعدة مرات أن يشكل طبقة صلبة مستمرة ملتصقة بقوة ولها خصائص زخرفية واقية. إنه طلاء مضاد للأشعة فوق البنفسجية. يتكون راتنجات البوليستر من بوليمر جزيئي عالي يحتوي على روابط استر في السلسلة الرئيسية, ويضاف راتنج الألكيد. يمكن تقسيم ممتص الأشعة فوق البنفسجية إلى سلسلة غير لامعة وعالية اللمعان وفقًا لللمعان. 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. مناسب بشكل خاص للديكور الداخلي واللوحات الإعلانية.
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.
يمكن تقسيم الطلاءات الفلوروكربونية إلى طلاءات فلوروكربونية تقليدية وطلاءات نانو فلوروكربون وفقًا لهيكل تشكيل طبقة السطح. . Coating manufacturers guarantee the service life of coatings starting from 10 سنين, 15 years to more than 20 سنين. 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 سنين, which actually proved the stability and durability of fluorocarbon coatings. The performance is 30 و 80 percent higher than the other two coatings, and the fluorocarbon coating ensures the use in various harsh environments.
