What are the powder-coated aluminium sheets for curtain walls? The spaying is a common seen coating method of color coated aluminum sheet, while the electrostatic spraying has powder spraying and fluorocarbon spraying two types. The POWDER COATED ALUMINUM SHEETS is processed by powder spaying which have low cost and applied in curtain walls. The raw materials of powder coating polyurethane, polyurethane resin, epoxy resin, hydroxy polyester resin and epoxy/polyester resin, which can be prepared in various colors. The characteristics of powder coated aluminum are: the spraying equipment has manual and automatic hanging type, coating thickness is more than 30 microns, the powder coated aluminum sheet coil has impact resistance, abrasion resistance, corrosion resistance, weather resistance, etc., and the coating price is lower than that of fluorocarbon. The powder coated aluminum can not stand the sun’s ultraviolet radiation as the fluorocarbon coating, after long-term exposure, the surface will cause natural fading. Another kind of electrostatic spraying is liquid spraying, also known as fluorocarbon spraying. It belongs to the high-grade spray, and the price is higher, the fluorocarbon coated aluminum sheet has been widely used in aluminum curtain wall. Due to its excellent characteristics, it has been increasingly valued and favored by the construction industry and users. Fluorocarbon surface painting has excellent resistance to fading, anti-blooming, anti-air pollution (acid rain, etc.), strong UV resistance, strong crack resistance and ability to withstand harsh weather conditions.
Why are curtain walls of luxury buildings made of aluminum plates? From the tallest Princess Tower to the dearest Hongkong Tianhui, why do designers of luxury buildings select aluminum wall panels as curtain walls as if they have made an agreement? Generally speaking, nowadays building designers choose materials based on three factors: aesthetic requirement, safety and environmental consideration. The metal reflectivity of aluminum panels gives off a grand noble elegance which makes a building more attractive, prominent and superior. The metal color or painted color can last decades without decaying. The curtain walls are of full closed type, and that effectively solves the problem of revealing of air conditioner and water supply pipelines. The safety of aluminium plates first refer to their light weight and good strength. With much smaller density than other metals, aluminum sheets weigh far less under the same size. The hardness of the panels and profile 6061 sheet is sufficient to withstand exterior pressure from the nature. Their tensile strength reaches 130MPA and cutting resistance 75MPA, overshadowing all other curtain wall materials. The other aspect of safety means that buildings with aluminum curtain walls are clear from water leakage problem which keeps irritating dwellers of buildings with stone and brick walls. There’s a gap of about 12mm between the curtain wall and the wall body, and there’s little possibility for water to leak. At the same time, the gap functions as an insulation layer that reduces the wall temperature effectively. This greatly saves power consumption of air conditioners in summer. Last but not least, the walls are made of PVDF PANINTED ALUMINUM PANELS . In comparison with common paintings, PVDF has stronger resistance against oxidation, acid rain, UV etc. Try an inquiry to aluminum manufacturer with twenty years experience:Laura@maynowei.cn0086 17622976371 (wechat, skype, whatsapp)
