Analysis of aluminium alloy window hardware fittings influence function
Aluminum alloy doors and Windows hardware fittings is the important component of the quality and performance of the function of window has the important influence. Due to the development of modern technology, doors and Windows hardware accessories (shake handshandle, armrest, slippery hold hinge, slippery course, fittings, etc), also more and more flood the market.
Modern building doors and Windows press profiles varieties can be roughly divided into: plastic window, composite materials window, aluminium alloy window, aluminium alloy window in China is now one of the mainbuilding doors and Windows products, in today’s architecture take a large proportion. In fact no matter from of wind, water tightness, air tightness, such as performance or from environmental protection, aluminium alloy window has its advantages.
Due to the aluminum alloy under natural conditions in the characteristics of the passivation extremely easily, hardware choose average metal materials, aluminum alloy doors and Windows of the form of the structure will be the big cathode small anode combination.
Using the new technology, new technology, new material is to improve the corrosion resistance of the doors and windows hardware fittings grants. Foreign hardware manufacturers by physical vapor phase coating (hereinafter referred to as PVD, also called a vacuum plating) produce appearance and corrosion excellent hardware accessories. Vacuum plating has strong adhesion, coating is not easy to fall off; Diffraction of uniform coating thickness; Coating density, pinhole bubble is less; before plating easy treatment, simple technology; With makings province, pollution-free, etc.
But in metallic and non-metallic on the surface of elemental, alloy plating or compounds. Once widely used in aviation, aerospace, electronic and optical and industry departments of various special properties of the preparation of coating. With the continuous improvement of the vacuum plating equipment, large-scale and continuous, and paint coating technology development, may obtain excellent adhesion and wear resistance, high brightness of decorative coating. Abroad of hand, hinge, etc in some parts surface, adopted vacuum plating Au, Ag, Al, Zr, TiN, lCrl8Ni9 etc, and obtain the outer surface of the excellent comprehensive performance, hold hands, cable accessories become a single function the use function and decorate double performance accessories.
Aluminum and all kinds of metal elements of all kinds of alloy made, with other material as the incomparable advantages, light quality and high strength, can be pressed to used each time all sorts of new complex profile materials. Experts predict, although in recent years the aluminum alloy doors and Windows in the low class under the impact of products, a weak market performance, but in the future of the development of real estate industry to lead, for aluminum alloy doors and windows resistance to corrosion, small amount of variant, fire the gender is strong, and long service life, environmental protection and energy saving features, it is still a decision on the market in the future of the mainstream.
In the early 1980s, aluminum alloy doors and windows in our country was published, due to its light weight, corrosion resistant, unique advantages of the original replace gradually the favour of steel window by consumer.
