Hello, Hengshui Baijin Rubber Products Co., Ltd. specializes in the production of polyurethane sealant products. Polyurethane sealant is divided into two types: two-component polyurethane sealant and single-component polyurethane sealant. Let’s talk about the uses of these two types of polyurethane sealants respectively.
1. Two-component polyurethane sealant is mainly used in the civil construction industry, transportation industry, etc.
? 1. Specific applications in construction include: connection of prefabricated concrete parts and other building materials and filling and sealing of construction joints, sealing and caulking around the wooden frames of doors and windows and between concrete walls, buildings Paste caulking of lightweight structures (such as curtain walls), waterproof caulking of balconies, swimming pools, bathrooms and other facilities, sealing of connections between air conditioners and other systems, sealing of insulated double-glazed glass and insulated window frames, etc.
? 2. In civil engineering, polyurethane sealant is used for caulking of high-grade roads, bridges, airport runways and other high-grade roads, bridges, airstrips and other areas with elastic joints, as well as sewers and underground sewers and underground materials made of concrete, ceramics, PVC and other materials. The connection sealing of gas pipelines, electric wires and circuit pipes and other pipeline joints, the sealing of subway tunnels and other underground tunnel joints, etc.
3. Polyurethane sealant can also be used for flexible joints of cables (such as underground cables), potting of electronic components, and dustproof and earthquake resistance; used in thermal insulation systems such as refrigerated trucks, cold storage insulation layers and Bonding and sealing of cryogenic containers, etc.
2. One-component polyurethane sealant product usage description:
? 1. Sealing of horizontal and vertical joints and filling of gaps between the concrete panels of the main structure of the building.
? 2. Sealing of gaps between residential doors and windows and concrete or brick walls.
? 3. Sealing of joints in building curtain walls, toilet ancillary equipment, etc.
? 4. Sealing of roof gaps to prevent leakage.
? 5. Sealing of all joints in air conditioning and ventilation systems.
? 6. Bonding and sealing at the interfaces of pipes made of various materials in the water supply and drainage system.
? 7. Sealing of pipe joints and leaks in the gas supply system.
? 8. Sealing of concrete panel joints in underground tunnels.
? 9. Sealant for double house glass and sealant for heat-insulated window frames.
?10. Caulking and sealing of elastic gaps on highways, bridges, airport runways, etc.
