Aluminum alloy windows

Aluminum window's glass can be adopted as: LOW glass, laminating glass, coated glass, ordinary insulating glass, single layer glass.

aluminum alloy: heat insulation broken bridge aluminum alloy window, ordinary aluminum alloy window, the surface treatment can be treated with oxidation, powder spraying, electrophoresis, fluorocarbon spray, fluorocarbon paint, series are: 50, 60, 70, 80, 90 and so on.

Aluminum alloy profiles are the main materials for making aluminum alloy doors and windows. There are 70 series, 75 series, 80 series, 85 series and 90 series of specifications for aluminum alloy sliding windows. The profies specifications of the aluminum alloy flat windows commonly used are 45 series, 50 series, 55 series and 60 series, it is suggested that customer should select the suitable profiles according to the design requirements of aluminum alloy doors and windows.

The section geometry size of aluminum alloy profiles for aluminum alloy doors and windows has been serialized. The product standard "aluminum alloy doors and windows" (GB/T 8478 - 2008) stipulates that the measured wall thickness of aluminum alloy doors and windows for production of aluminum alloy doors and windows should not be less than 1.1mm. There are no special requirements for drawing. Our company mostly adopts 1.4mm window profiles if customer no specific requirement.

The advantages of ordinary aluminum alloy windows are good weatherability and anti-aging ability,while shortcomings are heat insulation is not as good as other materials.

Aluminum alloy window of heat insulated broken bridge: adopting heat insulated broken bridge aluminum profile and hollow glass, it has the functions of energy-saving, sound insulation, noise-proof, dust-proof and waterproof. The K value of the heat transfer coefficient of the broken bridge aluminum window is below 3W/ K, which is less than half of the heat dissipation of the door and window, the heating cost is reduced by about 30%, the sound insulation is up to 29 decibels, and the water tightness and air tightness are good, which all reach the national A1 windows standard.

Surface treatment

1,Oxidation treatment: the oxide film is thinner, the thickness is about 0.5 ~ 4 microns, and it is porous, soft, and has good adsorbability.  It can be used as the base of the organic coating, but its wear resistance and corrosion resistance are not as good as the anodic oxide film; electrochemical oxidation, the chemical oxidation treatment equipment of aluminum and aluminum alloy is simple, easy to operate and high production efficiency. It does not consume electric energy, and has wide application range. It is not restricted by the size and shape of parts.

2.Powder electrostatic spraying: Powder electrostatic spraying profiles are characterized by excellent corrosion resistance, acid and alkali salt spray resistance is much better than the oxide colored aluminum door profiles. External protection and decoration for equipment are usually carried out on the basis of oxidation. Before the coating ,the aluminum parts should be pre treated before painting, so that the coating and workpiece can be firmly combined.

There are three methods of phosphating (phosphate), chromizing (chromium - free chromizing) and chemical oxidation.

3, electrophoretic coating aluminum alloy doors and windows: electrophoretic coating material surface gloss soft, can resist the cement, mortar acid rain of the invading, 90% of the aluminum doors and windows in Japan are coated with electrophoretic.

4, The fluorocarbon coating has excellent corrosion resistance and weatherability. It can resist acid rain, salt mist and various air pollutants. It has excellent cold and heat resistance. It can resist intense ultraviolet radiation,and can keep the color without fading and powdery for a long time, and has long service life.
