Ob hom li qub sib txawv thiab tsis tuaj yeem hloov pauv vim li cas hauv qab no:
1. Qhov sib txawv tseem ceeb ntawm cov roj hmab lined npauj npaim li qub thiab fluorine lined npauj npaim li qub yog cov khoom siv hauv ob sab phlu. Roj hmab hais txog cov roj hmab nitrile lossis Buna roj hmab, uas yog elastic thiab haum rau cov xov xwm dav dav xws li dej thiab roj, tab sis qhov kub thiab txias yuav tsum tsis txhob siab dhau. Fluorine yog PTFE (polytetrafluoroethylene) los yog fluororubber, uas yog ib qho nyuaj thiab nquag hnav thiab tsim kua muag. Nws yog tsim rau corrosive media thiab tuaj yeem tiv taus qhov kub siab tshaj li nitrile roj hmab thiab nitrile roj hmab.
2. Cov qauv ntawm cov roj hmab lined wafer npauj npaim li qub thiab fluorine lined wafer npauj npaim li qub yog tib yam, thiab qhov sib txawv ntawm ob tsuas yog txwv rau cov khoom siv ntawm lub rooj zaum valve sealing nto, ib qho yog cov roj hmab zoo tib yam thiab lwm yam yog fluorine roj hmab.
3. Cov roj hmab lined flange npauj npaim valve thiab cov fluorine lined flange npauj npaim valve tsis tsuas yog muaj cov khoom sib txuas sib txawv rau lub rooj zaum valve, tab sis kuj tau hloov pauv cov qauv.
