Selection of primary and secondary sealing materials for the floating disk in the storage tank for sulfolane solvent
Thread Content
Dear teachers: As the title suggests, which type of sealing material should be used for the primary and secondary seals of the internal floating disk in the sulfolane solvent storage tank?
For storage tanks holding sulfolane solvent, the selection of primary and secondary sealing materials for the internal floating disk should take into account chemical stability and corrosion resistance. It is recommended to use polytetrafluoroethylene (PTFE) or silicone rubber as sealing materials, as these two materials exhibit good chemical inertness and corrosion resistance to sulfolane. .
