New technical features of insulated aluminum alloy doors and windows: Apply insulated aluminum alloy profiles. The inner and outer aluminum alloy and the heat insulation strip are combined by rolling. Insulating glass is used to improve insulation performance and sound insulation. The utility model adopts an independent sealing structure, and the sliding window adopts a double-glue double-hair four-sealed structure; the flat-opening window utilizes an equal pressure principle, adopts a hard seal and two soft seal three-seal structures, and has excellent airtightness and watertightness. The use of high-grade accessories, beautiful shape, flexible operation, safe and reliable, is conducive to the insulation effect of doors and windows. Advantages of insulated aluminum alloy doors and windows: Reduce heat transfer: use heat-insulating aluminum alloy profiles, its heat transfer coefficient is 1.8 ~ 3.5W / m2 · k · h is much lower than ordinary aluminum alloy profiles 140 ~ 170W / m2 · k · h; using hollow glass structure, its heat transfer coefficient It is 3.17~3.59W/m2·k·h which is much lower than the common aluminum alloy profile of 6.69~6.84W/m2·k·h, which effectively reduces the heat conducted through the doors and windows. Prevent condensation: The temperature of the inner surface of the profile with the insulation strip is close to the room temperature, reducing the possibility of condensation of the interior moisture on the surface of the profile due to supersaturation. Energy saving: In the winter, the window frame with insulated strips can reduce the loss of heat through the window frame by 1/3; in the summer, if there is air conditioning, the window frame with heat insulation strip can be more Reduce energy loss Protecting the environment: Through the application of insulation systems, energy consumption can be reduced, while environmental radiation due to air conditioning and heating is reduced. Good for health: The heat exchange between the human body and the environment depends on the temperature of the indoor air, the air flow rate and the outdoor air temperature. By adjusting the temperature of the door and window, it is not lower than 12 ~ 13 ° C, has reached the most comfortable environment. Noise reduction: hollow glass structure and insulated aluminum profile cavity structure with different thickness can effectively reduce the resonance effect of sound waves, prevent the transmission of sound, and reduce the noise by more than 30dB. Colorful colors: After anodizing and powder coating, it can produce more than 200 different colors of aluminum profiles in RAL color. After rolling combination, the insulated aluminum alloy doors and windows produce two-color windows with different colors indoors and outdoors.

The so-called online auction refers to the price negotiation and trading activities carried out on the Internet, that is, the use of the Internet to publicly publish the information of the goods or services to be tendered on the website, and sell it to the highest or lowest bidder through competitive bidding. Its essence is a market economic process that takes competitive price as the core, establishes the communication and interaction mechanism between producers and consumers, and jointly determines the price and quantity, so as to achieve equilibrium.
