Aluminum Products Profile
Selection of aluminum products, first of all depends on its material. High quality aluminum alloy doors and windows with aluminum, thickness, strength and oxidation film, are in line with the requirements of the related state standards. Wall thickness should be more than 1.2mm, the film thickness up to 10 micron. If more than the national standard, or even meet European standards of products is the best choice. In the aluminium profile we can know that high quality aluminum alloy doors and windows, fine processing, installation is exquisite, good sealing performance, convenient switching. Poor quality of aluminum alloy doors and windows, materials and specifications are not up to standard, and the processing is also uneven, poor sealing performance, not only air leaks, and encountered strong winds and the external force under the condition of excessive prone to glass breakage phenomenon, cause the glass scraping or fall.
The Appearance of Aluminum Alloy Doors and Windows
Aluminum alloy doors and windows appearance is also the crucial link, surface of aluminum alloy doors and windows have artificial coloring oxide film and forming composite coating, such composite membranes not only corrosion resistance, wear resistance, and have a certain degree of fire prevention function, extremely high gloss, the choice should be as much as possible, try to choose the regular aluminum alloy doors and windows products manufacturers, selected processing precision, accurate, flexible opening and closing, no noise, and the decorative effect of refined products. In general, the quality of aluminum alloy doors and windows for high production cost, the price ratio of the inferior aluminum alloy door and window about 30% higher. There are only a wall thickness of 0.6-0.8 mm aluminum production of aluminum alloy doors and windows, the tensile strength and yield strength is much lower than the national relevant standards, use is very safe, not because of greed for cheap and ignored their safety factors. Aluminum alloy doors and windows usually assessment following properties: strength, air tightness, water tightness, opening and closing force, sound insulation, heat insulation, nylon guide wheel durability, locking and unlocking durability factor.
Aluminum Heat Sink Extrusions Technology
Aluminum electrophoresis refers to the extrusion of aluminum alloy is placed in the electrophoresis groove through the DC is formed on the surface of a layer of dense resin membrane process. Electrophoresis tank made of acrylic resin, solvent and water. The aluminum heat sink extrusions process includes electrophoresis, electrolysis, electrochemical deposition and other process. Aluminum electrophoresis painting after characteristics; acid resistance and alkali resistance, pollution resistance, delay the aging of aluminum profiles, durable, shiny bright, not easy to fade.
