Basic principles of glue-injection broken bridge insulation technology for aluminum profiles

The aluminum alloy profile is divided into two parts, the inner and outer parts, and polyurethane insulation glue is used to connect the two parts. By using pouring and cutting bridge methods, polyurethane insulation materials can isolate the heat conduction between the inner aluminum alloy profile and the outer layer, effectively preventing heat from transferring from warm indoors to cold outdoors. The processing method is: first, it is necessary to add a heat insulation groove when designing the profile. Then, pour the two-component heat-insulating castable glue into the heat-insulating tank in a certain proportion. Finally, after the heat-insulating casting glue reacts quickly to form a strong polymer, the temporary bridge at the bottom of the heat-insulating tank is cut off.
