Rectangular sealing strip
Rectangular sealing strip is a sealing material used to fill or seal rectangular gaps, usually made of rubber, silicone, fluororubber and other materials. Its cross section is rectangular, with good sealing performance and elasticity, and can be used for sealing and sound insulation in various mechanical equipment, building doors and windows, automobiles and other fields.
specification
Material: Common materials include nitrile rubber (NBR) fluororubber (FKM) silicone (VMQ) etc.
Size: Usually specified in terms of length (L) width (W) and thickness (T). For example the size of a rectangular sealing strip can be: L = 100mm W = 20mm T = 5mm. These dimensions can be customized according to specific needs to meet the requirements of different application scenarios.
Cross-sectional shape: Rectangular
Color: usually black gray white etc. can also be customized according to customer needs.
Quality control of rectangular sealing strips usually includes raw material inspection, production process control, finished product inspection and performance testing. Through strict quality control, ensure that the sealing strip has good sealing performance, durability and stability.
Rectangular sealing strips are widely used in the following fields:
Mechanical equipment: used to fill or seal the gaps of mechanical equipment to prevent liquid or gas leakage.
Building doors and windows: used for sealing door and window frames to prevent the intrusion of wind, rain and noise.
Automobile industry: used for sealing car doors, windows and other parts to improve the airtightness and comfort of the vehicle.
Clean the installation surface: ensure that the installation surface is clean, dry, free of oil and dust.
Determine the sealing position: determine the installation position of the sealing strip according to the position and gap to be sealed.
Cutting and installation: according to actual needs, cut the sealing strip into a suitable size and install it in the sealing position.
Storage: Rectangular sealing strips should be stored in a cool, dry and ventilated place, avoiding direct sunlight and high temperature environment.
Avoid contact with chemicals: Avoid long-term contact of rectangular sealing strips with oils, solvents and other chemicals to avoid affecting their performance.
Packaging and transportation methods:
Packaging: Usually plastic bags, cartons or boxes are used to protect the sealing strips from contamination or damage.
Transportation: Transportation by land, sea or air to ensure that the product is not damaged during transportation.
1. How to choose the right material for rectangular sealing strips?
- The choice of material should be determined according to the specific working environment and requirements. For example, NBR is suitable for general industrial occasions, FKM is suitable for high temperature and chemically corrosive environments, and silicone is suitable for high temperature and food-grade applications.
2. What is the temperature resistance range of rectangular sealing strips?
- The temperature resistance range of rectangular sealing strips of different materials is slightly different, usually between -40°C and +200°C.
3. How to check the sealing effect after the rectangular sealing strip is installed?
- After installation, you can check the sealing effect by applying some water or oil to the seal and observing whether there is leakage.
4. Can rectangular sealing strips be reused?
- Generally, rectangular sealing strips can be reused, but when removing and reinstalling, you should carefully check whether there is any damage on the surface to ensure the sealing effect.
