Double glazed louver partition is widely used in the indoor space partition of modern buildings. Its good airtightness and watertightness are crucial to ensure the comfort of the indoor environment, energy saving and avoid leakage. The sealing structure design is the key link to achieve these performances, which deserves in-depth discussion and research.
The sealing structure of double glazed louver partition mainly includes the sealing between glass and frame, the sealing between frame and wall or other adjacent structures, and the sealing at the shutter adjustment device. Rubber sealing strips are often used between glass and frame, and their material properties such as elasticity and weather resistance directly affect the sealing effect. Sealant is often used for the connection and sealing between frame and surrounding structure, and the viscosity, curing characteristics and aging resistance of the glue need to be considered.
In order to improve the airtightness, the size of the sealing strip should be accurately matched at the sealing point between glass and frame, and the installation should be tight and without gaps. A multi-channel sealing design is adopted, such as setting sealing strips on both sides of the glass to form a double barrier and reduce the air infiltration path. For the frame connection part, the connection method is optimized, such as using mortise and tenon structure or special connectors, and filling with sealant to ensure that gas is difficult to flow through the gap.
Watertightness mainly deals with the leakage of rainwater or other liquids. In terms of design, the sealing structure should form a reasonable drainage channel, such as setting a drainage groove at the bottom of the frame so that the infiltrated water can be discharged in time. The sealant between the glass and the frame should have good water resistance and adhesion to prevent water from penetrating from the edge of the glass. At the same time, special attention should be paid to the sealing at the shutter adjustment device to avoid damage to the seal due to the rotation of the shutter. A special waterproof sealing design can be adopted, such as a rubber sealing ring combined with a waterproof cover.
The selection of sealing materials is the key. High-quality rubber sealing strips should have high elasticity, low compression permanent deformation rate and good weather resistance, and can maintain sealing performance under different temperature and humidity environments. The sealant should be selected according to the use environment. For example, silicone sealant has excellent weather resistance and adhesion. During the construction process, strictly control the quality of materials, avoid using defective or expired materials, and perform installation operations in accordance with specifications.
In order to ensure that the airtightness and watertightness of the sealing structure meet the design requirements, strict testing is required. Use professional airtightness testers and watertightness test equipment to test in accordance with relevant standards. According to the test results, the sealing structure is optimized and adjusted. If leakage points are found, the causes are analyzed and the sealing design or installation process is improved until the performance meets the requirements.
The sealing structure design of double glazed louver partition has a decisive influence on its airtight and watertight performance. By carefully designing the sealing structure components, focusing on the key points of improving airtight and watertight performance, strictly selecting sealing materials and conducting quality control, and conducting testing and verification work, the sealing performance of double glazed louver partition can be effectively improved, providing a comfortable, safe and energy-saving partition solution for indoor space.
