Dab tsi yog cov ntaub ntawv ntawm diaphragm roj hmab
Hauv cov ntawv thov kev lag luam, ib qho ntawm cov khoom tseem ceeb ntawm lub diaphragm twj tso kua mis, ib qho cuab yeej uas tuaj yeem thauj tau ntau yam kev tshaj tawm, yog lub diaphragm. Cov khoom siv ntawm lub diaphragm muaj kev cuam tshuam ncaj qha rau kev ua haujlwm thiab kev pabcuam lub neej ntawm lub twj tso kua mis. Hauv tsab xov xwm no, peb yuav qhia ntau yam khoom siv roj hmab diaphragm, nrog rau lawv cov khoom thiab cov chaw siv.
EPDM (Ethylene Propylene Monomer)
EPDM yog cov roj hmab ua los ntawm copolymerization ntawm ethylene, propylene, thiab ib qho me me ntawm unconjugated diolefin. Nws yog lub npe hu rau nws zoo heev tiv thaiv kev laus, tshuaj, thiab dej. EPDM separators yog siv dav hauv cov khoom siv tsheb, cov khoom siv hauv tsev, thiab cov ntsaws ruaj ruaj. Nws muaj peev xwm siv tau ntev hauv qhov kub thiab txias ntawm -40 degree mus rau 130 degree thiab muaj ozone zoo thiab UV tsis kam.
PTFE (Polytetrafluoroethylene)
Polytetrafluoroethylene, tseem hu ua "Teflon", yog cov khoom siv polymer paub txog nws cov kev tiv thaiv zoo tshaj plaws thiab tsis nplaum. PTFE diaphragms yog resistant rau yuav luag tag nrho cov tshuaj, nrog rau muaj zog acids thiab bases. Nws kuj yog qhov kub thiab txias heev thiab tuaj yeem siv dav hauv qhov kub ntawm -196 degree txog 260 degree . Txawm li cas los xij, PTFE tsis tiv taus hluav taws xob thiab tuaj yeem ua rau muaj kev phom sij rau tib neeg hauv qee kis.
FKM (fluoroelastomer)
Fluoroelastomer yog cov khoom siv polymer uas muaj fluorine atoms, uas muaj huab cua zoo heev thiab tshuaj tiv thaiv. FKM separators yog resistant rau feem ntau cov organic thiab inorganic cov kuab tshuaj, nrog rau cov roj-raws li roj. Nws tuav lub zog txhua yam ntawm 200 degree, tab sis qee qhov ntim deformation yuav tshwm sim. FKM separators feem ntau yog siv rau hauv kev lag luam tshuaj, tsheb, thiab roj av.
NBR (Nitrile Butadiene Roj Hmab)
Nitrile roj hmab yog cov roj hmab hluavtaws ua los ntawm cov copolymerization ntawm butadiene thiab acrylonitrile, uas yog nyiam rau nws cov roj zoo heev thiab tshuaj tiv thaiv. NBR diaphragms tsim nyog rau kev xa cov khoom siv roj av, cov kua dej hydraulic, thiab lwm cov kua roj-raws li. Nws muaj kev ua tau zoo nyob rau hauv qhov kub thiab txias ntawm -20 degree txog 100 degree .
Neoprene
Neoprene yog cov roj hmab hluavtaws polymerized los ntawm chloroprene monomer, uas muaj cov roj zoo, tiv thaiv tshav kub, thiab kev laus ua haujlwm. Nws yog qhov tsim nyog rau kev tsim cov diaphragm twj tso kua mis diaphragms, tshwj xeeb tshaj yog nyob rau hauv lub tshav pob uas tsis yog-corrosive kua hloov, xws li dej phwj kho, kais dej, los yog seawater.
Nitrile roj hmab
Nitrile roj hmab zoo ib yam li neoprene tab sis muaj roj zoo dua thiab ua kom puas. Nws yog tsim rau kev xa cov roj av thiab cov kua roj xws li roj av lead, diesel, roj hydraulic, thiab lwm yam, nrog rau cov slurries uas tsis yog-corrosive nrog loj sib xws.
Lwm yam khoom siv
Ntxiv rau cov khoom siv roj hmab uas tau hais los saum no, kuj tseem muaj cov khoom sib cais tshwj xeeb xws li thermoplastic elastomers (TPEs), polytetrafluoroethylene copolymer (PTFE), thiab roj hmab elastomers. Cov ntaub ntawv no muaj kev xaiv ntau dua kom haum rau cov khoom siv sib txawv thiab cov yam ntxwv ntawm kev tshaj tawm.
Xaus
Xaiv cov khoom siv roj hmab diaphragm yog ib qho tseem ceeb los xyuas kom meej qhov kev ua tau zoo thiab kev ntseeg siab ntawm koj lub diaphragm twj tso kua mis. Txhua yam khoom muaj nws tus yam ntxwv ua tau zoo thiab ntau yam ntawm kev siv. Thaum tsim thiab xaiv lub diaphragm twj tso kua mis, yam xws li chemistry ntawm qhov nruab nrab, qhov kub thiab txias, qhov yuav tsum tau ua, thiab tus nqi-zoo yuav tsum tau muab rau hauv tus account. Nrog rau txoj kev loj hlob ntawm cov ntaub ntawv science, tej zaum yuav muaj ntau yam tshiab cais cov ntaub ntawv nyob rau hauv lub neej yav tom ntej kom tau raws li cov kev hloov ntawm kev lag luam.
