▪ Ethylene Propylene Diene Monomer (EPDM)
EPDM roj hmab ruaj khov rau cov khoom lag luam feem ntau, yog li nws tau siv dav hauv kev lag luam khoom noj.Lwm qhov zoo dua yog tias nws tuaj yeem siv tau ntawm qhov pom zoo ntawm 140 ° C (244 ° F), tab sis kuj muaj qhov txwv.EPDM tsis tiv taus cov roj organic, roj inorganic thiab rog, tab sis nws muaj kev tiv thaiv ozone zoo heev.
▪ Silicone Roj Hmab (VMQ)
Cov yam ntxwv zoo tshaj plaws ntawm silicone roj hmab yog tias nws tuaj yeem tiv taus kub ntawm -50 ° C (-58 ° F) txog li +180 ° C (356 ° F) thiab tseem khaws nws elasticity.Kev ruaj ntseg tshuaj tseem siv tau rau cov khoom lag luam feem ntau, txawm li cas los xij, dej qab zib lye thiab acids nrog rau cov dej kub thiab chav yuav ua rau cov roj hmab silicone puas, zoo ozone kuj.
▪ Nitrile Roj Hmab (NBR)
NBR yog ib hom roj hmab uas feem ntau siv rau kev ua haujlwm.Nws ruaj khov rau feem ntau cov hydrocarbons xws li roj, roj thiab roj, nrog rau dilute alkalis thiab nitric acid, thiab nws tuaj yeem siv rau qhov kub siab tshaj plaws ntawm 95 ° C (203 ° F).Txij li thaum NBR raug rhuav tshem los ntawm ozone, nws tsis tuaj yeem raug UV lub teeb thiab yuav tsum tau khaws cia ntawm lub teeb.
▪ Fluorinated Rubber (FPM)
FPM feem ntau siv rau qhov chaw uas lwm hom roj hmab tsis haum, tshwj xeeb tshaj yog thaum kub siab txog 180 ° C (356 ° F), nrog rau kev ruaj ntseg zoo.thiab tiv thaiv ozonerau feem ntau cov khoom, tab sis yuav tsum tsis txhob haus dej kub, chav, lye, acid thiab cawv.
▪ Polytetrafluoroethylene (PTFE)
PTFE muaj kev ruaj ntseg zoo heev thiab corrosion kuj (nws yog ib qho zoo tshaj plaws corrosion-resistant cov ntaub ntawv nyob rau hauv lub ntiaj teb no niaj hnub no, tshwj tsis yog rau molten alkali hlau, PTFE tsis yog corroded los ntawm tej tshuaj reagents).Piv txwv li, thaum boiled nyob rau hauv concentrated sulfuric acid, nitric acid, hydrochloric acid, cawv, los yog txawm nyob rau hauv aqua regia, nws qhov hnyav thiab kev ua tau zoo yuav tsis hloov.Ua haujlwm kub: -25 ° C txog 250 ° C
