Below, we will introduce the application of Jiangou silicone sealant in the field of construction.
The application of silicone sealant in the construction field began in the early 1960s. Silicone sealant has excellent aging resistance and can be used for more than 50 years under natural conditions. It has multiple colors and can match the colors of various building materials, making the appearance of buildings beautiful. It has good adhesion to building materials and is easy to apply. Its significant advantages in various applications have made silicone sealant successful in the construction industry.
Structural applications in building construction. Organic silicon building structural adhesive and organic silicon weather resistant sealant are used for bonding and sealing, which can reliably ensure the structural strength and stiffness of building curtain walls under loads such as airflow, wind pressure, ice and snow, and self weight. Silicone sealant is used to firmly and persistently bond curtain walls to aluminum frame materials, while silicone weather resistant sealant is used to fill expansion joints between curtain wall panels. Silicone sealant is an elastic material that can be stretched or compressed by 20% without being damaged in the event of severe vibration and deformation of buildings caused by occasional factors such as earthquakes, and effectively reduces the intensity and frequency of curtain wall vibration. Silicone weather resistant sealant has good water resistance, high and low temperature resistance, and aging resistance. Through its flexible connection, it can eliminate stress concentration and compensate for joint displacement that mechanical connections cannot withstand, allowing the curtain wall to withstand a large deformation of 1% in the plane.
Sealing applications in building construction. Such as the joints between panels and interior walls of high-rise buildings, the joints between door and window frames and door and window glass, the joints between prefabricated concrete slabs, marble, etc., the joints between ultra clean factories and cold storage facilities, the filling of gaps around kitchens, and the sealing of shower rooms, bathtubs, and urinals. It can also be used to repair cracks in walls and roofs.
Application in energy-saving glass processing for doors and windows. The insulation and sealing technology of energy-saving doors and windows is one of the key energy-saving technologies encouraged for development in China, and insulating glass is a representative of energy-saving materials for doors and windows. In the secondary sealing of insulating glass, the comprehensive performance of silicone sealant, such as aging resistance, service life, and environmental protection, is much better than polyurethane or polysulfide sealant. Therefore, more and more insulating glass secondary sealants are using silicone sealant.
