O-Ring FEP / PFA Encapsulated / Ntim

Qhuav Taw Qhia

Lub qhwv-ncig O-Ring muab cov elasticity thiab sealing zog ntawm cov roj hmab nrog cov tshuaj tiv thaiv ntawm Teflon. Nws muaj SILICONE roj hmab lossis FKM roj hmab sab hauv thiab nyias nyias Teflon FEP lossis Teflon PFA overcoat. , cov roj hmab no ntxiv rau Teflon O-RING muaj cov khoom sib khi zoo heev. Feem ntau, roj hmab O-RING yog ib qho yooj yim rau hnav, muaj cov tshuaj tsis zoo corrosion kuj thiab roj permeability tsis kam (tshwj tsis yog FFKM). Ntshiab Teflon O-RING muaj zog dua thiab tuaj yeem tiv taus compression tab sis tsis zoo elasticity. Sab nrauv Teflon FEP / Teflon PFA ORING muaj qhov ua haujlwm zoo rau cov kuab tshuaj o thiab tshuaj lom neeg ruaj khov (tshwj tsis yog nws raug tawm tsam los ntawm cov hlau, fluorine thiab qee qhov halides ntawm qhov kub siab), thiab O-RING nyob ze ntawm cov roj hmab muaj elasticity zoo, kev sib txhuam coefficient. ntawm Teflon FEP / Teflon PFA tsawg heev (tsuas yog 0.1 ~ 0.2), thiab nws muaj kev tiv thaiv zoo heev rau roj permeation. Cov khoom no ua rau cov coated O-Ring tiag tiag siv rau hauv qhov chaw hnyav.
