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 surface of the board used in the room is usually sprayed with resin coating, which can not adapt to the bad outdoor environment. If it is used outdoors, it will accelerate its aging process and cause discoloration and 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 construction units deceive the owners, and use the indoor panels to imitate the quality of anti aging and corrosion resistant fluorocarbon sheets to squeeze unreasonable profits, thus causing serious discoloration and decolorization of the aluminum plate used in the project.
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. In the past, China's silicone rubber mainly rely on imports, its value makes many people flinch, only those high rise buildings on the curtain wall project worth daring to dare to ask. 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. In the past, in the construction, there have been such quality problems, we once thought that the quality of the plate itself; later, through the focus of analysis, it is found that the main problem is sticking on the base plate of aluminum plastic board, followed by the quality 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 construction of glue, some construction personnel in order to save time, without paper glue to ensure the regular and tidy, but use the protective film of aluminum plastic board surface as a substitute. Due to the cutting of aluminum plastic plate, the protective film will have different degrees of tearing, so it can not be used as a substitute for protective tape, it is impossible to clean up the glue seam neatly.
