Beijing Diya Sanitary Ware Production Mode of Broken Bridge Aluminum Doors and Windows in Shijiazhuang Yuan Teng

There are two main production methods of thermal insulation profiles. One is to form a "thermal insulation bridge" with thermal insulation strip and aluminum profile through mechanical tooth opening, threading and rolling, which is called "threading" of thermal insulation profile; The other is to pour the heat insulation material into the heat insulation cavity of aluminum alloy profile, and then remove the broken bridge metal through solidification to form "heat insulation bridge", which is called "pouring" heat insulation profile.

The inner surface and the outer surface of the heat insulation profile can be profiles with different sections or profiles with different colors with different surface treatments.

However, due to the influence of geography and climate, the linear expansion coefficient of thermal insulation materials and aluminum profiles has been avoided, and there is a large stress and gap between them when they expand when heated and contract when cooled. At the same time, heat insulation materials and aluminum profiles are integrated, and they are equally stressed with aluminum in doors, windows and curtain wall structures.

Therefore, thermal insulation materials must have tensile strength, bending strength, expansion coefficient and elastic modulus close to those of aluminum alloy profiles, otherwise the thermal insulation bridge will be broken and destroyed.

Therefore, the selection of thermal insulation materials is very important.
