1. Shortly after use, the silicone rubber sealing strip becomes hard and brittle, and loses its elasticity and sealing function;
2. Shrink and fall off within a short time after installation;
3. False installation of sealing strips due to structural reasons;
阳光照射或受热后，密封条发粘。 4. After being exposed to sunlight or heat, the sealing strip becomes sticky.
Solution: In the selection of sealing strip materials under various chemical conditions, it must be in accordance with the actual situation. When considering the cost factor, it must also take into account the material's environment and working conditions. Under normal circumstances, fluorine rubber seals can be used at high temperatures; cold-resistant seals can be used at low temperatures.
In the case of bottom corrosion, a seal with good comprehensive performance can be selected, such as EPDM rubber seal; if it is to reach food grade, silicone rubber seal manufacturers can choose silicone rubber seal .
