[China Aluminum Network] aluminum alloy doors and windows have a good function, light weight, beautiful, good lighting, durable, easy to receive profiles and re-application rate, no pollution and other characteristics have been liked by people. However, the poor thermal insulation of the frame material affects the function of the aluminum doors and windows. Therefore, the improvement of its thermal insulation and energy-saving functions is a technical issue that will be dealt with in the future of aluminum alloy doors and windows, and it is also a preference for the development of doors and windows enterprises.
To improve the structural design to improve the functions and levels of existing doors and windows, it is necessary to improve the structural design, and to improve the construction of low-level structures that only use provincial workers, materials, and low prices, and to complete the functions of the sliding window. Case-based windows are the main transitions, completing the design of diversified systems such as single-layer, double-layer, three-layer, and small-opening fixed.
Pay attention to the selection of raw materials The general requirements of the frame material should be good strength, good insulation, easy to make all kinds of shapes, but also easy to accept the takeover and is conducive to situation maintenance. The aluminum alloy window frame material should improve its heat insulation function, should make the broken bridge or compound type.
2 Glass should be used for insulating glass, and low-E type hollow glass should be used in the north. In the south, solar-coated glass should be used in areas where solar radiant heat predominates. The booming countries in foreign countries have no need for single glass and white glass at all, because they are not willing to save energy and improve their living conditions.
(3) Insulating glass made of double-channel seals and made of polysulfide hollow glass glue should be used. The distance between the insulating glass should be a continuation of the angled structure. If a four-corner plug-in type is used, butyl rubber must be used for sealing at the joints. . Single-pass sealing of insulating glass is not effective, and the use of silicone structural sealant for secondary sealing of insulating glass is not a good choice, due to their shorter service life.
