At present, the use of aluminum profiles is more and more widely, aluminum profiles have high strength, light weight, strong stability, corrosion resistance, good plasticity, small deformation, no pollution, non-toxic, strong fire resistance, long service life (up to 50-100 years), good recycling, can be remade.
Over the years, all countries in the world have used 6063 aluminum alloy (nearly 100 kinds of aluminum alloy) as a door and window frame. Mainly in order to the metal surface anodizing effect is good, the beginning of anodizing is white, after further changing the electrolyte to achieve bronzing, these two main colors have been used in the country for more than ten years.
10 years ago, the domestic Jiangsu Changzhou has introduced aluminum surface flour spraying technology, which can spray a variety of colors, but at that time, the economic conditions did not allow, and the second is that the market did not recognize the colorful doors and Windows, which is ugly.
With the rapid development of the domestic economy, people’s aesthetic views have also changed, now people think that the color of white, bronze aluminum doors and Windows is monotonous, not rich and colorful, and then require a variety of colors, green, yellow, red, blue, only green and six kinds of more.
Aluminum in the extrusion process, such as the extrusion mold is not very good or the mold extrusion aluminum too much, the surface of aluminum will produce extrusion marks, the hand may touch the surface of aluminum uneven, in order to make the surface of aluminum smooth and flat, can not touch the extrusion marks, aluminum factory generally first with alkali corrosion, corrosion off the extrusion marks.
Sand blasting technology is an advanced method for the surface treatment of aluminum profiles in recent years, which uses special sand high-speed jet to abrade the extrusion marks on the surface of aluminum profiles. In fact, several well-known domestic large aluminum factories, aluminum extrusion export because of good mold, equipment, advanced technology, no extrusion marks, there is no need to sandblast.
The user does not purchase aluminum in order to request the finish, but requires “sandblasted aluminum”. In fact, the aluminum profile that has not been sandblasted is really good aluminum.
