Common aluminum composite panel Quality Analysis

Plastic composite board is based on a composite coating chemically treated surface materials, polyethylene plastic core material processed in special aluminum composite panel production line. Since the late eighties early nineties as a new type of decorative material imported from Korea and Taiwan to China, with its economy, optional color diversity, convenient method of construction, excellent processing performance, must good fire resistance and noble qualities, people of all ages quickly. Aluminum composite panel in recent years has entered the home decoration, because of its smooth surface, colorful, strong impact resistance, easy to clean, durable, fast construction has been widely adopted.

Home decoration aluminum composite panel is generally used in the dining room, kitchen, bathroom and room heating cover, cut off shape, construction, first the plate base surface to dry flat, preferably with multilayer, Blockboard do underlying prevent crack and deformation. Second paste aluminum composite panel to pay attention to the gluing must be uniform to be the glue thinner volatile touch sticky hands to paste with a wooden hammer percussion compaction. Third, aluminum plate Note that when used according to design requirements is divided into a number of blocks. Should not be the whole or a large area, otherwise easily lead to the hollowing open plastic. Aluminum composite panel seams matchboard glass glue sealing requirements of glass, plastic injection seal must be uniform and full and you want to clean up the surface dry clean, line thickness consistent.

The wall engineering board of aluminum composite panel and interior wall decorative board two categories, home decoration generally use the latter. Aluminum composite panel is divided into two kinds of duplex and simplex. Sided aluminum composite panel surface are rust-proof high-strength aluminum alloy plate. Positive spray, negative aluminum color. The single-sided aluminum composite panel, only the surface layer of aluminum alloy plate, somewhat less intensity, the price is cheaper. Quality of the surface of the painting, a good aluminum-plastic spray process imported hot pressing, film color uniformity, strong adhesion, zoned touch is not easy to paint stripping.

Characteristics of aluminum composite panel

Aluminum composite panel is easy to process, the molding material. The pursuit of efficiency, quality products to fight for time, it can shorten the duration and reduce costs. Aluminum composite panel can be cutting, cutting, slotting, band saw, drilling, processing countersunk, can also be cold-formed, cold folding, cold-rolled, also can be riveting, screwing or gluing adhesive etc..

Common quality problems

Aluminum composite panel glue seams and edges

Aluminum composite panel in the renovation of the building surface, the gap between the plates generally have a certain width. For aesthetic needs, are generally required to fill in the gap in the black sealant. Gluing some construction workers need in order to save time, not paper tape to ensure the gluing neat, the rules, but to use the surface of the protective film of aluminum composite panel as a substitute. Aluminum composite panel cutting, protective film will produce different degrees of tearing the protective tape alternatives do with it, it is not possible to glue seam straight and neat.

Chipboard discoloration, bleaching

Aluminum composite panel discoloration, decoloration, improper sheet selection. Aluminum composite panel is divided into indoor board and outdoor board, the surface coating of the two plates, and decided to apply different occasions. Plates, used by the indoor surface spray resin coating, this coating can not adapt to the harsh outdoor natural environment, will accelerate the aging process if used in outdoor, naturally, causing discoloration discoloration. Outdoor surface coating of the aluminum plate is generally used in anti-aging, anti-UV ability bomb lipid coating of polyvinyl fluoride, this sheet is expensive. Some construction unit to deceive owners, posing as anti-aging, anti-corrosion quality fluorocarbon plate, squeeze unreasonable profits, resulting aluminum plate used in the engineering of severe discoloration, discoloration indoor sheet.

Chipboard open plastic off

Open plastic, aluminum composite panel off, mainly due to the improper selection of binders. As a the ideal outdoor aluminum composite panel works binder, silicone rubber has a unique advantage. Previously, the China silicone rubber is mainly dependent on imports, its worth discourage a lot of people, only those who are worth a lot of money on a high-rise building curtain wall engineering dared cares. Now, China's Zhengzhou, Guangdong, Hangzhou has put into operation a different brand of silicone rubber, causing prices to plunge. Now, in the purchase of aluminum composite panel sales Chamber of Commerce recommended the kind of dedicated fast rubber. This glue is acceptable for indoor use with the outdoor climate variability, giving rise to the plate to open the rubber off phenomenon.

Aluminum composite panel surface deformation, from the dark

Casually stroll on the circle in which city, are not difficult to find some of the aluminum composite panel surface deformation, from the big drum unpleasant engineering. Little facade renovation project on this phenomenon, a large high-rise buildings on this phenomenon. Construction this quality problems, we have considered the quality of the plate itself reason; Later, after everyone's centralized analysis found, the main problem lies in the paste aluminum composite panel grassroots plate, followed by aluminum-plastic the quality of the board itself. Dealers often provide us with the aluminum plate construction technology, the recommended primary materials HDF, wood panels and the like. In fact, the use of such material in outdoor life is very fragile, wind, sun, rain, would have a deformation. Since the grassroots materials are deformed, then as a surface layer of aluminum composite panel that no deformation of the reason? Visible, the ideal outdoor grassroots material after anti-rust treatment angle iron, square steel tubes formed skeleton better. If conditions permit, the use of aluminum as a skeleton on the more desirable. The skeleton of the type of metal material, its cost is not higher than wood keel, high-density board many can be assured that the quality of the project.

Materials include:

The main technical indicators: aluminum composite panel coating thickness, gloss deviation, pencil hardness, adhesion, impact resistance, acid, alkali, oil, solvents, etc..

The current market price of the cost of materials aluminum composite panel about a 60-100 yuan (1220X2440mm) 20-30 yuan per square meter, the thickness of 3mm, about 0.05 mm thick aluminum plate.

Labor costs: aluminum composite panel ceiling wood keel, digging lights hole, MDF grassroots, aluminum composite panel adhesive (the keel pitch 400-600MM) 18 yuan / square meters which type of light steel keel including scaffolding, actinomycetes, mix material, Keel fabrication and installation, smallpox storey 3M to 11 yuan / square meter; wooden keel 10 yuan / square meter.

Paper seal on wood joist or light steel keel including closure plate lights dug hole 4 yuan / square meter.
