1. Selection of sealing materials
Rubber sealing ring: Rubber sealing ring is one of the commonly used sealing materials for F-Style Oblong Can. Choose high-quality rubber sealing ring to ensure that it has good elasticity and corrosion resistance.
Silicone pad: In some new detection methods, the use of silicone pad can further improve the sealing performance. Silicone pad has good flexibility and sealing performance.
2. Sealing structure design
Double-layer sealing: The use of double-layer sealing structure can significantly improve the sealing performance. For example, the combination of primary sealing and secondary sealing can effectively prevent leakage.
Tongue-shaped sealing belt: Some new designs use tongue-shaped sealing belts. Through special structural design, it is ensured that the sealing belt fits tightly with the can wall, further improving the sealing effect.
3. Detection method
Water test: Fill the can with water, seal it and turn it upside down to observe whether there is water leakage. This is a simple and intuitive detection method.
Pressure test: Use a vacuum pump or a manual vacuum pump to extract the air in the can to create a low-pressure environment. Observe whether the can maintains its shape and there is no air leakage.
Bubble test: Fill the can with water and seal it, and observe whether bubbles escape from the edge of the can or the lid. The appearance of bubbles indicates that there may be problems with the sealing.
Professional equipment detection: For occasions requiring high-precision testing, professional sealing test equipment such as vacuum suction cups and pressure sensors can be used to accurately measure the pressure difference between the inside and outside of the can.
4. Regular maintenance and inspection
Visual inspection: Regularly check whether the can body and lid have cracks, dents or damage, and check whether the sealing ring has wear or aging.
Regular replacement of seals: Even if the seal performs well in the test, it should be replaced regularly to prevent sealing failure due to aging.
5. Sealing measures for special application scenarios
Nitrogen sealing protection system: For F-Style Oblong Can that stores volatile or hazardous liquids, a nitrogen or other inert gas sealing protection system can be used to prevent gas leakage.
Floating roof tank seal: In some large storage tanks, the floating roof design can reduce the contact between liquid and air, reduce volatilization losses, and reduce edge sealing losses through efficient sealing structures.
