高性能分离膜生产设备液体槽用橡胶密封型材的研制

Development of Rubber Sealing Profiles for Liquid Tanks in High-performance Separation Film Production Equipment

介绍了高性能分离膜生产设备液体槽用橡胶密封型材的工作原理、配方组成和工艺设计。结果表明,采用EPDM基材、白炭黑/高岭土补强体系、硫黄/过氧化二异丙苯/N-环己基-2-苯并噻唑次磺酰胺/三烯丙基异氰脲酸酯并用硫化体系,研制的橡胶密封型材具有优异的耐水性、耐酸碱性、耐次氯酸钠性、耐溶剂性、高回弹性、低变形、耐老化性和高抗污染性等;有效解决了液体槽槽体与独立辊架横梁之间的密封,确保了生产过程中的稳定性和液体处理膜质量控制。

The working principle,recipe and process design of rubber sealing profiles for liquid tanks in high-performance separation membrane production equipment were introduced.The results showed that the rubber sealing profile developed by using EPDM,silica/kaolin reinforcing system,sulfur/diisopropylene peroxide/N-cyclohexyl-2-benzothiazolesulfonamide/triallyl isocyanurate vulcanization system had excellent water,acid and alkali,sodium hypochlorite,solvent resistance,high resilience,low deformation,aging resistance and high pollution resistance.It effectively solved the sealing between the liquid tank body and the independent roller frame beam,ensuring stability in the production process and quality control of liquid treatment film.
