First, the history of ceiling
Ceiling mainly used in airports, railway stations, office buildings, shopping malls, subway stations and residential and other places. There will be a gypsum board, mineral wool board, PVC, smallpox, etc. aluminum gusset and soft.
The first generation of products are gypsum board, mineral wool board;
The second generation is PVC;
The third-generation products are metal ceiling.
Now gypsum board, mineral wool board also constantly improving, there are water-proof gypsum board and mineral wool sound-absorbing panels. But they plate a single, easy to scrub for the next frame keel installation, multi-use project. PVC Products poor oxidation resistance, non-moisture-proof, non-fire, easy to deformation, discoloration, used for old-fashioned common home-improvement. With people's demands to improve the quality of the decoration, home decoration has now basically done using aluminum gusset ceiling.
Second, the development prospects of aluminum gusset ceiling
aluminum gusset plate due to more flowing lines, rich color, appearance good effect, more fire, moisture, easy to install, easy to clean and so on, designers and clients according to the color of furniture and floor colors to choose ceiling, by the consumption of earth's welcome, has now been recognized by the world. Smallpox from the gypsum board, mineral wool board, PVC,the development of aluminum gusset so far has been quite a long time. aluminum gusset is only spraying when the advent of pre-board, and later developed into the Roller Coating then coated, (of which coating used for home improvement,) is now on the market such as PVC coated film produced in Japan, emerged in a PET film, more environmental protection, to that extent, aluminum gusset in the next few years the prospects are very good.
Third, decided to aluminum gusset's quality and price positioning of the main factors
The aluminum material for the ceiling are aluminum alloy, there can be no pure aluminum (pure aluminum is too soft, strong enough). However, due to the different alloy content resulting in the mechanical properties of aluminum alloy is different from the current domestic aluminum alloy material for the ceiling is divided into five grades of approximately：
First grade: aluminum-magnesium alloy, also contains a part of the manganese, the material of the biggest advantages is the antioxidant capacity well, and also because of the manganese content, and therefore has a certain strength and stiffness, are doing the best smallpox material. Southwest China aluminum smelter performance of the most stable.
Second grade: Al-Mn alloy, the material strength and stiffness slightly better than Al-Mg alloy. However, antioxidant capacity slightly lower than the Al-Mg alloy. If both sides have carried out protection, processing, basically to solve their antioxidant capacity weaknesses better than aluminum-magnesium alloy, the domestic western Fujian aluminum and aluminum to aluminum Switzerland the most stable performance.
3rd grade: aluminum alloy, the alloy of manganese and magnesium content of less. Therefore, its strength and stiffness were significantly lower than the aluminum-magnesium alloy and aluminum-manganese alloy. Because of its soft, easy to process, as long as a certain thickness, can basically meet the most basic flatness requirements of smallpox. Antioxidant capacity but obviously not as good as aluminum-magnesium alloy and aluminum-manganese alloy. And the processing of transport and installation process easy deformation.
4th grade: ordinary aluminum alloy, the mechanical properties of such materials is not stable.
5th grade: This board raw materials are melted aluminum ingot processing plant would be beaten up aluminum, does not control the chemical composition. As the chemical composition of out of control, the performance of these materials very unstable, resulting in a serious non-smooth surface, product deformation, and easily oxidized.
From the above there are several pairs of raw materials, sub-grade technology, we is not difficult to analyze each type of ceiling molding after quality assurance. The best Lvkou Ban, their main raw materials are used, aluminum magnesium alloy southwestern Sweden Fujian aluminum plate and aluminum-manganese alloy. Now many people think that the thicker the plate like, with the above analysis of several raw materials are able to know, in the case the same raw materials, then the thicker the plate the better, but the case of the fifth grade of the board, and then thickness is not.The other surface treatment, and some manufacturers of raw materials did not meet a certain thickness, but in order to pursue the thickness of this statement, the surface processing, on the multi-layer coating spray. When consumers buy aluminum gusset on the original plate material can not have a good understanding of, the easiest way to hand feel the strength and hardness of aluminum.
