Introduce why the bridge cutoff aluminum insulation strip should be used in the lower window door products
Bridge cutoff aluminum windows and doors are very popular modern window and door commodities. The bridge cutoff aluminum insulation strip in its prefabricated components plays the role of heat insulation, wind blocking and rain blocking, and has excellent practical effects of environmental protection and energy conservation, which has been praised by people.
Like other plastic products, non anti-aging is a common symptom of plastic products. According to relevant research, general engineering plastics have obviously aged indoors for at least many months and more than two years, and their physical properties have been reduced to varying degrees. Therefore, the technical standard of nylon heat insulation strip also requires the aging resistance of door and window sealant strip. After the conditions of 140 ℃± 2 ℃ and 100h are solved, the characteristic root of its transverse compressive strength is specified to exceed 50MPa. Because nylon heat insulation strips are used for windows, doors and building curtain walls, the service life index value of the design scheme is generally more than 20-30 years, which also meets the requirements of the reality. Therefore, it is very important to carry out further scientific research on the anti-aging characteristics of thermal insulation bridge breaking materials, especially the prediction and analysis of static data service life indicators of nylon thermal insulation strips.
Analysis of Transverse Bending Strength Characteristics of Broken Bridge Aluminum Insulating Bars
The bridge cutoff aluminum thermal insulation strip (acrylic resin 66. PA66) is one of the important types of engineering plastics. The thermal insulation bridge cutoff made of polyester 66+25% glass fiber as the main raw material has high impact toughness, good wear resistance, self lubrication and thermal stability. It is mainly used to connect the core of the inner and outer frames of the aluminum alloy profile thermal insulation profile to a part of the core. It has the function of cooling and heating bridges. It has excellent ultra-low temperature characteristics, can self rest, and is resistant to corrosion of most carbonate solutions, oil and organic solutions. In addition, the thermal expansion coefficient of glass fiber reinforced polyester 66 thermal insulation bridge cutoff is close to that of aluminum alloy profiles, and the overall performance is good after composite with aluminum profiles. Practical experience has proved that this is also an ideal aluminum door and window insulation material successfully developed and designed today.
Accompanied by the implementation of one part of the technical standard: bridge cutoff aluminum insulation strip, people from all walks of life have paid attention to the quality of thermal insulation bridge cutoff products. The new standard has brought a solid quality evaluation index system for the thermal insulation broken bridge used for curtain wall doors and windows in China in the future. Because the curtain wall doors and windows will be subjected to a certain degree of transverse air pressure in different use scenarios, the transverse bending strength characteristics of nylon insulation strips on both sides of aluminum alloy profiles are important indicators to measure the deformation resistance of raw materials. At this stage, there are no standards and specifications for testing the transverse bending strength of acrylic resin insulated broken bridges in the sales market. Therefore, scientific researchers have determined the appropriate testing conditions for testing the transverse bending strength of acrylic resin insulated broken bridges through scientific research on different interface tests and the impact of the load speed of the tensile machine on the transverse bending strength of insulated broken bridges.
That's all for the explanation of bridge cutoff aluminum insulation strip. Thank you for watching. Let's see you next time.
