Aluminum plastic panel - common quality problems analysis
1, aluminum plate discoloration, decolorization
The discoloration and decoloration of aluminum plastic plate are mainly due to improper selection of plates. The aluminum-plastic plate is divided into indoor and outdoor boards, and the surface coating of the two kinds of boards is different, which determines its applicable different occasions. The plate used for indoor, the general surface spraying resin coating, the coating can not adapt to harsh natural environment, if used in outdoor, natural will speed up the process of aging, causing discoloration discoloration. The surface coating of the outdoor aluminum plastic board usually selects the coating of polyurethane coating which has strong anti-aging and anti ultraviolet ability, which is expensive. Some of the construction unit owners, high-quality fluorocarbon sheet material by posing as indoor use of aging resistance, corrosion resistance, not to a reasonable profit, resulting in the emergence of aluminum engineering discoloration, bleaching phenomenon is serious.
2, the aluminum plate open and fall off
Aluminum plate open and fall off, mainly due to the improper selection of binder. As an ideal binder for the outdoor aluminum plastic plate project, silicone rubber has unique advantages. Previously, China's silicone rubber is mainly dependent on imports, the price prohibitive for many people, only those high-rise building expensive curtain wall project to buyers. Now, China's Zhengzhou, Guangdong, Hangzhou and other places have been put into production of different brands of silicone rubber, resulting in price drop. Now, in the purchase of aluminum plate, the sales chamber recommended that special quick drying glue. This glue use can be used in indoor, outdoor climate is constantly changing, plastic, sheet off phenomenon.
3. Deformation and bulging of aluminium plastic sheet surface
Just on which a circle around the city, are not difficult to find some aluminum plate surface deformation, the engineering spoil the enthusiasm of the drum. Small facade decoration project on this phenomenon, large high-rise buildings also have this phenomenon. Before the construction, had this quality problem, we have considered the quality of the plate itself; then, after we found the concentration analysis, the main problem in the base plate pasted aluminum plate, followed by the quality problems of aluminum plate itself. Dealers often provide us with aluminum plate construction technology, the recommended use of basic materials are mainly high-density board, wood board and so on. In fact, such materials are used outdoors, the service life is very fragile, after the wind, sun, rain, will inevitably produce deformation. Since the basic materials are deformed, then as the surface layer of aluminum plastic board that there is no distortion of the rationale? It can be seen that the ideal outdoor base material should be treated with anti rust treatment, and the angle steel and square steel tube form a skeleton. If the conditions permit, the use of aluminum as a skeleton is more ideal. This kind of metal material of the skeleton, the cost is not high, high density wood keel plate many, can do to ensure project quality.
4, aluminum plate glue sewn neatly
Aluminum plate in the decoration of the surface of the building, there are generally some width gap between the plates. In order to meet the needs of beauty, the black sealant should be filled in the gap. In the glue some construction personnel in order to save time, not paper tape glue neatly, ensure the rules, but the use of protective film on the surface of the aluminum plate as a substitute. The aluminum plate in cutting, tearing protective film will produce different degrees, so use it to do protective tape alternatives, it is not possible to glue neat.
