What are the "bright spots" of new hot aluminum door and window hardware system technologies?

[China Aluminum Industry Network] New Technology Advantages of Hot Aluminum Door and Window Accessories: Use rolling method to combine aluminum alloy and heat insulation strips inside and outside. Insulated aluminum alloy doors and windows use insulating glass to improve insulation performance and sound insulation. Adopt independent sealing structure, push-pull window adopts double-rubber double-branch four-sealing structure; flat-open window uses isobaric principle, adopts one hard seal and two soft seal three-sealing structure, and has excellent air tightness and water tightness. Select high-end accessories, beautiful shape, flexible operation, safe and reliable hot aluminum doors and windows are conducive to better insulation of doors and windows. The advantages of heat insulation aluminum alloy door and window accessories are as follows: Reducing heat conduction: heat-insulating aluminum alloy material, whose thermal conductivity coefficient is 1.8-3.5W/m2·k·h, which is much lower than ordinary aluminum alloy material 140～170W/m2·k·h. Insulating glass structure, its thermal conductivity coefficient For 3.17 ~ 3.59W/m2 · k · h is much lower than the ordinary aluminum alloy 6.69 ~ 6.84W/m2 · k · h, effectively reducing the heat conduction through the door and window accessories. Anti-condensation: The temperature of the inner surface of the profile with the insulating strip is close to the room temperature, which reduces the possibility that the indoor moisture will condense on the surface of the profile due to over-saturation. Energy savings: In winter, window frames with thermal insulation can reduce 1/3 of the heat lost through the window frame; in the summer, if there is air conditioning, the window frame with thermal insulation can be more Reduce the loss of energy Protecting the environment: Through the application of thermal insulation systems, energy consumption can be reduced while reducing the environmental radiation due to air conditioning and heating. Health: The exchange of heat between the human body and the environment depends on the temperature of the indoor air, the speed of air flow, and the temperature of the outdoor air. By adjusting the interior temperature of doors and windows so that it is not lower than 12 ~ 13 °C, has reached a more comfortable environment. Reduce noise: The use of hollow glass structures with different thicknesses and heat-insulating aluminum cavity structures can effectively reduce the resonance effect of sound waves, prevent sound transmission, and reduce noise by more than 30 dB. Colorful and colorful: After anodizing and powder coating surface treatment, it can produce more than 200 different colors of aluminum in RAL color system. After rolling and pressing, the insulated aluminum alloy doors and windows produce indoor and outdoor two-color windows with different colors.
