What are the door and window curtain wall seals? Sealing strip fixed advantage

January 21, 2023

The doors and windows used in high-rise buildings not only require good decorative effects, but also excellent sound insulation, heat insulation, sealing and dustproof performance. Accessory curtain wall strips for doors and windows ensure that all of the above excellent performance is achieved. If the door and window curtain wall seals are not properly selected, it will cause quality problems. Then everyone will follow the Xiaobian together to see the relevant content of the door and window curtain wall seals .

First, the sealing strip's fixing method advantages


1) Embedding advantages: easy to install and replace, you can first assemble the window on the wall and then assemble the strip; Disadvantages: easy to fall off when subjected to large external force.


2) Advantages of wearing people: good fit with profiles, not easy to fall off; disadvantages: not easy to replace, must be worn before the profile group window.


3) Adhesive strip is glued to the contact part of the strip and the profile. When the adhesive protective film is peeled off during construction, the strip can be directly adhered to the profile (used for interior doors and windows, anti-collision parts of furniture) .


Second, the performance of high temperature vulcanization SiR High temperature vulcanization SiR has many unique advantages:


1) The surface is smooth and the colors are various.

2) Excellent cold resistance and heat resistance. SiR can be used for a long time in a temperature range of 70,200 ° C, especially suitable for use in countries with large latitudes.


On the windows and walls of the summer sun in the south of China, the temperature can easily reach 70 °C, while the winter temperature of -40 °C in the Mohe area is also very common. The huge temperature difference makes PVC, thermoplastic elastomer (TPE/TPR), EPDM sealing strip The use is severely constrained: general plastics, rubber or elastomers are already embrittled at 20 ° C and cannot be applied even at 0 ° C. The SiR has almost no change in physical properties in the temperature range of 50200 °C.


3) Excellent weathering resistance. The natural aging resistance and ozone aging resistance of SiR is superior to other known rubbers and elastomers. Because the surface energy of SiR is low, it does not adhere to organic matter, and under the action of sun, rain, water and ozone, it is aged for 30 years, and its performance is not significantly reduced.


4) Good compressive deformation ability (Table 1), the deformation of high temperature SiR is only 10% after 70 h at 150 °C. The hardness of SiR can be adjusted between Shore 3055 A to achieve the best sealing performance.


5) Good human safety.


6) Good air permeability and selective air permeability. The oxygen transmission rate of SiR is 25 times that of natural rubber and 428.6 times that of butyl rubber (IIR), which is beneficial to maintain the freshness of the living room air.


How about, I read the relevant introduction to the door and window curtain wall seals, and I also learned a lot about the door and window curtain wall seals.
