Analysis of aluminum plate - common quality problems
1, aluminum plate color, decolorization
Aluminum plate discoloration, discoloration, mainly due to improper selection of board. The aluminum plate is divided into indoor and outdoor plate plate, two plates of different surface coatings, determines the different applicable 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 outdoor aluminum plate is generally used in anti-aging, polyvinyl fluoride coating elastic fat strong UV resistance, this plate 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 outdoor aluminum plate engineering, silicone rubber has excellent conditions richly endowed by nature. 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 prices. Now, in the purchase of aluminum plate, sales chamber of Commerce recommended that special glue. This glue use can be used in indoor, outdoor climate is constantly changing, plastic, sheet off phenomenon.
3, aluminum plate surface deformation, drum
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. This small window decoration, 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 the construction technology of aluminum plate, the recommended base material is mainly high density board, wood board etc.. In fact, this kind of material used in outdoor, its service life is very fragile, through wind, sun and rain, will produce deformation. Since the base material is deformed, then as aluminum plate surface layer that has no deformation of the reason? Thus, the outdoor base material should be ideal after anti rust treatment of angle steel, square steel tube skeleton form is preferred. If conditions permit, using aluminum as frame 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 seams and glue
Aluminum plate in the decoration of the building surface, the gap with a certain width generally between plates. In order to satisfy the aesthetic needs, are generally required to fill in the gaps in the black sealant. 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.
