Broken Bridge aluminum doors and windows products are recognized by consumers because of their excellent heat insulation and sound insulation functions. At the same time, with the continuous development of the Broken Bridge aluminum doors and windows industry, many powerful brands have emerged.
When choosing Bridge-cutoff aluminum alloy, various factors should be considered comprehensively. Here are some small experiences that I hope will be helpful to you. 1. Window surface: the window frame should be clean, smooth, smooth, with no scratches or bumps on the large surface and no open welding fracture on the profile. 2. Hardware: the hardware should be complete, the position is correct, the installation is firm, the use is flexible, and the use function can be achieved. 3. Glass sealing strip: the contact between the sealing strip and glass and glazing rebate should be smooth, and no curling or grooving should be allowed. 4. Sealing quality: When the doors and windows are half closed, there is no obvious gap between the fan and the frame, and the sealing strip on the sealing surface should be in a compressed state. 5. Glass: The glass should be flat, installed firmly, and there should be no looseness. Single-layer glass should not directly contact the profile. The inner and outer surfaces of double-layer glass should be clean, and there should be no dust and water vapor in the glass interlayer, barrier cannot be cocked. 6. Layering: the layering with sealing strip must be tightly attached to the glass. There should be no obvious gap at the joint between the layering and the profile, and the joint gap should be less than or equal to 1mm. 7. Splicing materials: splicing materials should be closely connected with window frames, and sealed with caulking paste at the same time, without shaking. The spacing between screws should be less than or equal to 600mm, and both ends of lined reinforced steel should be fixed firmly with the opening. 8. Switch parts: the flat opening, sliding or rotating window should be closed tightly. 9. Connection between frame and wall: The window frame should be horizontal and vertical, and the height should be consistent. The spacing between the fixed pieces should be less than or equal to 600mm. The frame and the wall should be firmly connected. The gap should be filled with elastic materials and filled with full, and the surface seam paste should be sealed, no cracks. 10. Drainage hole: the position of the drainage hole should be correct, and it should be smooth at the same time. The quality of Windows produced in the market is mixed. How to identify its advantages and disadvantages? It can be observed mainly from three aspects, namely profiles, hardware accessories and processing technology. 1. From the aspect of profiles, the surface finish of profiles, the rationality of cavity structure, the wall thickness of profiles and the rationality of profile coordination are all the standards to measure the advantages and disadvantages of profiles. At present, the profiles used in windows in Shanghai have some famous brand products produced by designated manufacturing enterprises, which basically adopt foreign patent formula and have stable and reliable quality. 2. From the aspect of hardware accessories, the identification of its advantages and disadvantages mainly depends on its flexibility, sealing performance, wear resistance and corrosion resistance. The accessories mainly consider the lined steel placed in the profile cavity. The Good lined steel should be galvanized A3 steel with a wall thickness of at least 1.2mm. At present, some production stalls often do tricks on lined steel to reduce prices, attract businesses and deceive consumers. 3. From the perspective of processing technology, its quality mainly depends on the appearance quality of doors and windows, the accuracy of processing size, low angular strength, and the matching rationality of hardware accessories. Aluminum Alloy is a kind of non-ferrous metal structural material widely used in industry and has been widely used in aviation, aerospace, automobile, machinery manufacturing, ships and chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welded structural parts is increasing day by day, which makes the research on the weldability of aluminum alloy further. The wide application of aluminum alloy promotes the development of aluminum alloy welding technology, and at the same time, the development of welding technology expands the application field of aluminum alloy. Therefore, the welding technology of aluminum alloy is becoming one of the research hotspots. The density of pure aluminum is small (& rho;= 2.7g/cm3), About 1/3 of iron, low melting point (660 ℃), aluminum is a face-centered cubic structure, so it has high plasticity (& delta;:32~40), & psi;:70 ~ 90%), easy to process, can be made into various profiles and plates. Good corrosion resistance; But the strength of pure aluminum is very low, and the annealing State & sigma; B value is about 8kgf/mm2, so it is not suitable for structural materials. Through long-term production practice and scientific experiments, people gradually strengthen aluminum by adding alloy elements and using heat treatment and other methods, thus obtaining a series of aluminum alloys. The alloy formed by adding certain elements can have higher strength while maintaining the advantages of pure aluminum such as light weight, & sigma; B values reach 24 ~ 60kgf/mm2 respectively. In this way, its "specific strength" (the ratio of strength to specific gravity & sigma; B/& rho;) is better than many alloy steels and becomes an ideal structural material, which is widely used in machinery manufacturing, transportation machinery, in terms of power machinery and aviation industry, aircraft fuselage, skin, gas compressor, etc. are often made of aluminum alloy to reduce self-weight. Using aluminum alloy instead of steel plate welding, the structural weight can be reduced by more than 50%. Aluminum Alloy has low density, but high strength, close to or over high quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and anticorrosion, and is widely used in industry, the usage is second only to steel. Aluminum Alloy is divided into two categories: cast aluminum alloy, used in cast State; Deformed aluminum alloy, able to withstand pressure processing, can be processed into aluminum alloy materials of various forms and specifications. It is mainly used for manufacturing aviation equipment, building doors and windows, etc. Aluminum alloy can be divided into deformed aluminum alloy and cast aluminum alloy according to the processing method. Wrought aluminum alloy is divided into non-heat treatment enhancement type aluminum alloy and heat treatment enhancement type aluminum alloy. Non-heat treatment enhancement type cannot improve mechanical properties through heat treatment, but can only be strengthened through cold processing Deformation. It mainly includes high purity aluminum, industrial high purity aluminum, industrial pure aluminum and rust-proof aluminum. Heat-treatable enhancement type aluminum alloy can improve mechanical properties by means of heat treatment such as quenching and aging. It can be divided into hard aluminum, forging aluminium, super hard aluminum and special aluminum alloy. Some aluminum alloys can use heat treatment to obtain good mechanical properties, physical properties and corrosion resistance. Cast aluminum alloy can be divided into aluminum-silicon alloy, Aluminum copper alloy, aluminum magnesium, Aluminum-zinc alloy and aluminum-rare earth alloy, among which aluminum-silicon alloy has simple aluminum-silicon alloy (which cannot be strengthened by heat treatment, has low mechanical properties and good casting properties), special aluminum-silicon alloy (which can be strengthened by heat treatment, high mechanical properties, good casting performance),2008 Beijing Olympic Games torch "xiangyun" is aluminum.
