Detailed introduction

 Dalian broken bridge aluminum doors and windows

Dalian broken bridge aluminum doors and windows There are two main production methods of thermal insulation profile. One is to use heat insulation strip material and aluminum profile to form a "heat insulation bridge" through mechanical tooth opening, threading, rolling and other processes, which is called "strip through type" of thermal insulation profile; The other is to pour the thermal insulation material into the heat insulation cavity of aluminum alloy profile. After solidification, the bridge breaking metal is removed to form the "heat insulation bridge", which is called "pouring type" heat insulation profile.

The inner and outer surfaces of the thermal insulation profiles can be profiles with different sections or different colors with different surface treatment methods. However, due to the influence of region and climate, large stress and gap between thermal insulation material and aluminum profile can be avoided due to the large difference of linear expansion coefficient between thermal insulation material and aluminum profile; at the same time, the thermal insulation material and aluminum profile are combined into a whole, which is the same as aluminum in the structure of doors, windows and curtain walls. Therefore, the thermal insulation material should have the tensile strength, bending strength, expansion coefficient and elastic modulus close to the aluminum alloy profile, otherwise the heat insulation bridge will be broken and damaged. Therefore, the selection of thermal insulation materials is very important.
