[CHINA ALUMINUM NETWORK] Heat-dissipating aluminum profiles can be divided into two categories according to the processing technology: roll-embedded and glue-injected. At present, there is no corresponding standard for heat-insulating aluminum profiles. In Europe, the heat-dissipating system generally adopts a pass-in process. In North America and South Korea, AAMATIR-A8-90 structural specifications for aluminum-alloy heat-insulating aluminum alloy structural sections for injection molding are implemented. China's broken bridge thermal insulation curtain wall and door and window products are both pass type and plastic injection type.
(1)Rolling and embedding is the special heat insulation strip for aluminum doors and windows, inserted into the special slots of two aluminum profiles inside and outside, rolled by special machinery, and the insulation strip is connected with the internal and external profiles. This method is in Europe. All countries, especially Germany, Italy, and other countries in Central Europe are widely used.
(2) The basic principle of the plastic injection type is to divide the aluminum alloy profile into two parts, using a specially formulated polymer insulating polymer - a heat-insulating adhesive for bonding. As a result, an effective heat insulation layer is formed between the inner and outer parts of the Baiyin aluminum alloy profile, so that the way to dissipate the heat through the door window frame or the fan profile is blocked, thereby achieving the purpose of high energy efficiency heat insulation.
