ã€China Aluminum Industry Network】Aluminum plastic board has entered the home decoration in recent years, because it has a smooth appearance, colorful, strong impact resistance, convenient cleaning, durable, convenient construction and is widely used. Aluminium-plastic panels are divided into two categories: external wall engineering boards and interior wall decorative boards. The latter is usually used for home decoration. Aluminium-plastic board is divided into two sides and one side. The double-sided aluminum-plastic panels are rust-proof high-strength aluminum alloy panels. Front spray, reverse aluminum nature. The single-sided aluminum-plastic plate only has a layer of aluminum alloy plate on the outside, and the strength is slightly poor, and the price is also cheaper. The appearance of paint quality, good use of imported aluminum-plastic hot-press spraying process, paint film uniform color, strong adhesion, scratch after the paint is not easy to remove.
Aluminum plates for home decoration are usually used in restaurants, kitchens, bathhouses, and room heating covers, partitions, etc. When constructing, the first plate base must be boring and flat. It is better to use a multilayer board or blockboard as the bottom layer to avoid Attack cracking deformation. Secondly, it is necessary to notice that the adhesive must be even when the aluminum-plastic panel is posted. After the strong plastic thinner is volatilized, it can be posted by touching it with a sticky hand and tapping it with a wooden hammer. Third, when the aluminum-plastic composite panel is in use, it should be divided into several pieces according to the planning requirements. Should not be used throughout the entire area or in large areas, otherwise it will lead to empty drums. Fourth, the aluminum-plastic plate joints are usually sealed with glass glue. When the glass glue is sealed, it must be evenly full. After drying, the outer surface should be cleaned and the thickness of the lines should be common.
Aluminium composite panel features
Aluminium plastic plates are good materials for easy processing and molding. It is a commodity that seeks efficiency and time, and it can shorten the construction period and reduce the cost. Aluminium-plastic panels can be cut, cut, grooved, band sawed, drilled, and processed with meditation. They can also be cold-formed, cold-folded, and cold-rolled. They can also be riveted, screwed, or glued together.
Common quality questions analysis
Discoloration and decolorization of plastic panels
Discoloration and decolorization of aluminum-plastic panels are primarily due to the improper selection of panels. Aluminium-plastic panels are divided into indoor panels and outdoor panels. The outer coatings of the two panels are different, which determines the applicable occasions. The panels used in the interior are usually coated with a resin coating. This coating cannot adapt to the harsh outdoor environment. If it is used outdoors, it will naturally accelerate its aging process and cause discoloration and discoloration. The exterior coating of outdoor aluminum-plastic composite panels is usually made of a polyfluoroelastomerum coating with anti-aging and anti-ultraviolet resistance. The price of this kind of plate is expensive. Some construction companies have deceived the owners to use indoor panels to pretend to be resistant to aging and corrosion-resistant high-quality fluorocarbon plates and to exploit unreasonable profits. Therefore, aluminum sheets used in the construction process have experienced severe discoloration and decolorization.
Plastic plate opening and falling
Aluminium-plastic panels have been opened and dropped mainly due to improper selection of adhesives. As the ideal binder for the outdoor aluminum-plastic board project, silicone rubber has unique advantages. At one time, China's silicone adhesives relied heavily on imports, and their worth was daunting to many people. If only those expensive high-rise building curtain projects would dare to look. Today, China's Zhengzhou, Guangdong, Hangzhou and other places have put into production a different brand of silicone rubber, resulting in a sharp drop in prices. Today, at the time of the purchase of aluminum-plastic board, the seller will introduce the special kind of quick-drying adhesive. The glue is still used indoors and used outdoors in climate change, showing the appearance of sheet opening and falling.
Distortion and drumming of aluminum-plastic panel
It is not difficult to find some projects in which the appearance of aluminum-plastic panels is distorted and drums are burned. The appearance of this small facade decoration project is also reflected in large high-rise buildings. Once in the construction, this kind of quality doubt was presented. We used to think that it was the quality of the plate itself. Later, through our concentrated analysis, we discovered that the first question is on the bottom sheet of the aluminum-plastic composite board, followed by aluminum-plastic. The quality of the board itself is questionable. Distributors often provide us with construction techniques for aluminum-plastic panels. The underlying data used in the introduction are mainly high-density boards, wood boards, and the like. Originally, when such data was used outdoors, its service life was very weak. After wind, sun, and rain, it was bound to be deformed. Already the underlying material has been deformed, then as a surface layer of aluminum-plastic plate that there is no distortion of the reason? Visible, the ambulation of the underlying data should be through the anti-rust treatment after the angle steel, square steel pipe frame is better. If the conditions permit, the use of aluminum profiles as skeletons will be even more ambitious. The skeleton of this type of metal data is not much more expensive than wood keel and high density boards, and it can indeed ensure the quality of the project.
Aluminum plastic plate glue regularity
When aluminum-plastic composite panels are used to decorate buildings, there is usually a gap of a certain width between the panels. For beautiful needs, it is usually necessary to fill the gap with a black sealant. During construction, some construction workers do not use paper tape to ensure the regularity and rules of plastic injection in order to save time. Instead, they use the maintenance film of aluminum-plastic panel as an alternative. Because when the aluminum-plastic panel is cut, the maintenance film will have a different degree of tearing, so use it as a substitute for the maintenance tape, and it will not be able to tidy up the glue.
The data contains:
The main technical indicators of aluminum-plastic plate: coating thickness, gloss error, pencil hardness, adhesion, impact resistance, acid, alkali, oil, solvent, etc.
The data fee aluminum plastic panel current market price is about 60-100 yuan a (1220X2440mm) about 20-30 yuan per square meter, thickness 3mm, aluminum thickness 0.05 mm
Labor costs: Aluminium-plastic panel ceiling includes wood keel, dig light hole, MDF bottom layer, aluminum-plastic plate adhesive (keel distance 400-600MM) 18 yuan / square meter Where light steel keel contains scaffolding, put line, mix Materials, keel manufacturing equipment, ceiling 3M to 11 yuan / square meter; wood keel 10 yuan / square meter.
Wooden keel or light steel keel sealing paper cover, dig light hole 4 yuan / square meter
The aluminum keel board surface layer on the wooden keel includes the device and digs the light hole 4 yuan/square meter.
Silicone construction sealant not counted.
