The ceiling of metal ceilings originates from Europe and the United States and other countries. Ten years ago, the decoration of aluminum ceilings (mainly aluminum-magnesium ceilings) was considered as high-end products, and the price was also around 200 yuan. It was rarely used in the country. Now with the improvement of technology and technology The transformation of aluminum ceilings has begun to be rationalized in terms of price.
First, the development history of smallpox
Ceilings are mainly used in airports, railway stations, office buildings, shopping malls, subway stations and residential buildings. There are plasterboards, mineral wool boards, PVC, aluminum gussets, and soft ceilings on the market.
The first generation products are gypsum board and mineral wool board;
The second generation is PVC;
The third generation of products is metal ceilings.
Now gypsum board, mineral wool board is also constantly improving, there are waterproof gypsum board and sound-absorbing mineral wool board. However, they have a single plate type and are not easily scrubbed. They are used for installation of a lighter keel and are used in engineering. PVC products have poor oxidation resistance, are not moisture-proof, fire-proof, easily deformed, and discolored, and are often used in old-fashioned ordinary homes. With the improvement of the quality of the decoration of the people, now the home decoration has basically been using aluminum buckle board to do the ceiling.
Second, the development prospects of aluminum buckle smallpox
Due to the large number of aluminum buckle plate types, smooth lines, rich colors, good appearance, and more fire-proof, moisture-proof, easy to install, easy to clean, etc., designers and customers can choose the ceiling of the ceiling according to the color of the furniture and the floor color. Welcomed by consumer goods, it has now been recognized by the world. It has been a long time since the development of ceilings from plasterboards, mineral wool boards, PVC, and aluminum buckle boards. When the aluminum buckle plate was first introduced, it was only a spraying plate, and later it developed into a roller coating and then a coating film (more of which was used for home decoration.) This coating is a PVC film on the market and a PET film is produced in Japan. In view of environmental protection, the outlook for aluminum buckling boards in the next few years is very good.
Third, the market ceiling brand
Currently, there are many aluminum buckle plate manufacturers on the market. In the supermarkets, foreign well-known brands mainly include â€œLeslon of the Netherlandsâ€ and â€œSimon of the United Statesâ€. The famous domestic brands mainly include â€œXifeiâ€ and â€œModern (Ossbau)â€. "Brilliant", "West Aluminum" and so on. In fact, most of the so-called imported brands use imported technology and imported production lines. Their production processing plants and raw materials are all domestic.
IV. Main factors determining the quality and price positioning of aluminum buckles
The aluminum materials used for the ceiling are all aluminum alloys, and it is impossible to have pure aluminum (the pure aluminum is too soft and the strength is not enough). However, due to the different alloy contents and the different mechanical properties of aluminum alloys, the aluminum alloys currently used in domestic ceiling materials are divided into five grades:
The first grade: aluminum-magnesium alloy, also contains part of manganese, the biggest advantage of this material is good anti-oxidation ability, at the same time because of the content of manganese, so it has a certain strength and rigidity, it is the best material for making smallpox. The performance of aluminum processing in the Southwest Aluminum Factory in China is the most stable.
Second grade: aluminum-manganese alloy, the strength and rigidity of this material is slightly better than aluminum-magnesium alloy. However, the antioxidant capacity is slightly lower than that of aluminum-magnesium alloys. If both sides of the protective treatment, basically to solve its anti-oxidation ability is not as good as aluminum-magnesium alloy good shortcomings, the domestic aluminum and Rui Aluminum Aluminum processing performance is the most stable.
The third grade: aluminum alloy, the alloy has less manganese and magnesium content. Therefore, its strength and rigidity are significantly lower than aluminum-magnesium alloys and aluminum-manganese alloys. Because it is soft and easy to process, as long as it reaches a certain thickness, it can basically meet the most basic flatness requirements of smallpox. However, its antioxidant capacity is obviously inferior to aluminum-magnesium alloy and aluminum-manganese alloy. And it is easy to deform during processing, transportation and installation.
Fourth grade: ordinary aluminum alloy, the mechanical properties of this material is not stable.
The fifth grade: The raw material of this kind of plate is the aluminum processing plant melting aluminum ingots into aluminum plates and does not control the chemical composition at all. Due to the uncontrolled chemical composition, the properties of these materials are extremely unstable, leading to serious irregularities on the surface of the product, deformation of the product, and extreme oxidation.
From the above points on the classification of raw materials, we can easily analyze the quality assurance of each type of ceiling molding. The best aluminum gussets, their main raw materials are used in the southwestern aluminum-magnesium alloy plate and Raychem aluminum aluminum-manganese alloy plate. Now many people think that the thicker the plate is, it can be understood through the above analysis of several raw materials, if the same raw materials, then the thicker the better the plate, but if the plate is the fifth grade, then thick is not. Another surface treatment, some manufacturers do not achieve a certain thickness of raw materials, but in order to pursue the thickness of the statement, in the surface treatment, spray a layer of paint. Ordinary consumers do not have a good understanding of the material of the original plate when they purchase the aluminum pinch. The simplest way is to feel the strength and hardness of the aluminum plate by hand.
