Since the end of the 1970s, China's aluminum alloy doors and windows, the curtain wall industry began to start, the promotion and application of aluminum alloy glass curtain walls in the building, from nothing, from imitation to self-developing, from the construction of small projects to contract Large-scale engineering projects, from production construction, low-end products to production high-tech products, from low-rise building doors and windows to the construction high-level glass curtain wall, from only the high-grade models that can only process simple medium and low-grade profiles to extrusion comprades, from relying on imports to import The external contracting project, aluminum alloy doors and windows and glass curtain walls have been quickly developed.
By the 1990s, the emergence of new building materials has promoted the further development of the building curtain wall. A new type of building curtain wall has appeared in all parts of the country, namely a metal curtain wall, and the so-called metal curtain wall is a building wall of the wall panel material for a metal sheet. Simply put, it is to replace the glass in the glass curtain wall into a curtain wall form of a metal sheet, but due to the difference between the difference between the face, it should be considered in the design. Due to the excellent processability of the metal sheet, the variety of colors can be fully adapted to the design of various complex shapes, which can arbitrarily increase the recessed and protruding lines, and various types of curve lines can be processed. The architects have been favored by the architect with a huge way, and thus the development of sharp flying.
The flat light polishing groove is usually provided that there are two major purposes of this slot, that is, the aluminum alloy treated with sand polishing and eliminates gray.
1 flat light polishing: flat light polishing tanks can generate a thickness of oxide film, and can greatly increase the brightness of aluminum. Since the anodization causes the aluminum alloy after the sand, first-line polishing treatment, the surface light is formed, and the surface light forms a dense oxide layer, and the luster is fixed down, and then the anodization is reduced, and the loss is reduced; in addition, Shenyang aluminum Profiles are polished from sand surface to the anode oxidation, it is necessary to wash it, and may be stedomed in air or water washing tanks, producing corrosion, and prefabricate the chemical oxide film of a certain thickness, to avoid it. In the oxidation, a pycloid or flower material is produced in the water washing tank and improve the yield.
