What is the thermal insulation broken bridge aluminum profile?

The heat-insulating bridge doors and windows have high strength and aging resistance. It can also be remanufactured, reused, recycled, reprocessed, and not wasted.

What is the thermal insulation broken bridge aluminum profile?

  As the main material of the aluminum alloy heat insulation broken bridge doors and windows—insulation broken bridge aluminum profiles have a good heat conduction performance.

  In order to insulate and heat insulation, the domestic introduction of the“thermal insulation broken bridge” technology to produce a “thermal insulation broken bridge "Aluminum profile", in the middle of the two aluminum profiles by adding a low thermal conductivity of non-metallic separators, can get excellent insulation properties of aluminum insulation, called "insulation broken bridge aluminum profiles." Advantages of heat-insulating bridge doors and windows: The heat-insulating bridge doors and windows have high strength and aging resistance. It can also be remanufactured, reused, recycled, reprocessed, and not wasted. The state clearly pointed out that the selection of doors and windows should consider energy saving and strength in the first place. Based on this, aluminum insulation profiles, with their superior performance, have pointed out the direction for the development of aluminum profiles in China. In order to avoid the insufficiency of the aluminum itself, a heat-insulating aluminum profile was developed. The principle of the aluminum heat-insulation is to penetrate the aluminum insulation bar and break the aluminum profile to form a broken bridge, which creates a block inside and outside the house. The barrier of hot and cold exchange effectively prevents the conduction of heat. It not only retains the advantages of aluminium profiles, but also greatly reduces the heat transfer coefficient of aluminum profiles (the entry "heat transfer coefficient" is provided by the Encyclopedia of the industry), and the energy saving effect is relatively good is the best choice for energy saving doors and windows. Isolation strips used for heat-insulating bridge aluminium profiles - is a polyamide nylon with reinforced glass fiber, a non-metallic separator with a very low thermal conductivity, so it has a good thermal insulation performance, in the same heat supply Under the circumstances, the use of heat-insulated bridge doors and windows than the ordinary doors and windows of the indoor temperature increased by 5 degrees Celsius or more, can be called a new energy-saving doors and windows.

  There are two main production methods for heat-insulating profiles (insert “insulation profiles” provided by the Encyclopedia of Industry): one is the use of heat-insulating strip materials and aluminium profiles, which are formed through mechanical teething, threading, rolling and other processes. “Insulation bridge” is called “insulation type” of heat insulation profile; the other is to pour insulation material into the insulation cavity of aluminum alloy profile, and after solidification, remove the broken bridge metal and other processes to form “insulated bridge”. "," called "casting" thermal insulation profiles. The inside and outside surfaces of the heat insulation profile can be profiles of different sections (words “section” is provided by the Industry Encyclopedia), or different color profiles of different surface treatments (words “surface treatment” provided by the Industry Encyclopedia). Due to geographical and climatic influences, there is a large gap between the coefficient of linear expansion of heat-insulating materials and aluminium profiles, and there is a large stress and gap between the two during thermal expansion and contraction; at the same time, heat insulation materials and aluminium profiles are combined. One, on the doors and windows, is equally as strong as aluminium. Therefore, it is required that the heat insulation material must also have the tensile strength, bending strength, expansion coefficient and elastic modulus close to the aluminium alloy profile, otherwise the heat-insulating bridge may be broken and destroyed.
