Perfluoroelastomer Center
Perfluoroelastomers (FFKM) yog ib tsev neeg tshwj xeeb ntawm cov tshuaj thiab cov cua sov elastomers. Nrog rau txoj kev loj hlob ntawm fluoroelastomers (FKM) hauv xyoo 1950, muaj kev xav tau ntau ntxiv rau cov polymers nrog cov tshuaj tiv thaiv ntau dua thiab muaj peev xwm tiv taus qhov kub siab dua. Yug los ntawm qhov kev xav tau no thaum xyoo 1960s lig, perfluoroelastomers muab cov tshuaj tiv thaiv ntawm PTFE nrog qhov yooj thiab elasticity ntawm cov pa FKM.
Lub sijhawm los yuav FFKM yog thawj zaug tsawg thiab txwv rau cov txheej txheem tshuaj lom neeg thiab qhov chaw ua haujlwm. Tab sis qhov ntau thiab ntev ntawm FFKM sai sai tau coj mus rau nws txoj kev saws me nyuam nyob rau hauv ntau yam kev siv. Perfluoroelastomers tam sim no tau siv dav hauv kev txhim kho kev ua haujlwm siab FFKM O-rings siv hauv kev ua tshuaj lom neeg thiab kev thauj mus los, roj thiab roj, thiab kev lag luam aerospace, txo qis sijhawm thiab txuas ntxiv kev pab cuam lub neej hauv ntau cov txheej txheem kev lag luam.
SJK tau tsim ntau yam khoom siv perfluoroelastomer rau ntau yam kev lag luam thiab kev siv. FFKM O-rings, cov ntsaws ruaj ruaj thiab gaskets yog qee yam khoom siv uas peb tsim nrog FFKM. Hauv kev nrhiav kev ua tau zoo, peb tau tsim peb tus kheej tshwj xeeb FFKM uas muaj qib siab tshaj plaws ntawm kev ua tau zoo thiab feem ntau tuaj yeem siv rau hauv cov ntawv thov uas lwm cov polymers tsuas tuaj yeem ua tsis tau.
Cov khoom ntawm FFKM O-rings
FFKM O-rings muab tshuaj zoo heev thiab kub ua haujlwm. Lawv muab cov sealing quab yuam, tsis kam thiab rov ua haujlwm ntawm cov pa elastomeric O-rings nrog cov tshuaj tsis haum ntawm PTFE. FFKM's carbon-fluorine daim ntawv cog lus yog suav tias yog qhov muaj zog tshaj ib daim ntawv cog lus hauv cov organic chemistry, lav cov tshuaj siab, kub thiab oxidation tsis kam hauv peb cov FFKM O-rings tiav.
Cov ntsiab lus fluorine nce ntxiv txhim kho cov tshuaj tiv thaiv ntawm hydrocarbons. Yog li ntawd, FFKM muaj 72.5 feem pua fluorine, nrog rau cov pob txha fluorinated tag nrho, qhov siab tshaj plaws ntawm fluorination tau, thaum tseem khaws cov khoom elastomeric uas yuav tsum tau muaj rau cov tshuab sealing. FFKM's ether pawg (ROR) muab nws cov khoom elastomeric thiab elasticity, tsis muaj cov perfluoroelastomers yuav coj zoo li PTFE.
FFKM polymer saw tseem muaj peb lub monomer hu ua kho qhov chaw monomer (CSM). Thaum ua tiav raws li txoj cai, qhov no tso cai rau tsim cov kev sib txuas ntawm peb sab. Qhov kev sib txuas peb sab no tsis tsuas yog ua kom cov khoom siv elasticity, tab sis kuj nce qhov siab tshaj plaws kev khiav hauj lwm kub ntawm FFKM saum toj no lub melting point ntawm PTFE, muab FFKM lub siab tshaj plaws thermal stability thiab tshuaj tiv thaiv ntawm tej elastomer.
Feem ntau, 3 hom kev kho tshuab siv nyob rau hauv perfluoroelastomers, muab FFKM O-rings ntau yam ntawm kev ua tau zoo. tag nrho cov no yog:
Peroxide Kho - Qhov no muab FFKM qib siab tshaj plaws ntawm cov tshuaj tiv thaiv thaum muab kub ua haujlwm. Qhov kev kho no tau ua tiav tiav hauv kwv yees li 90 feem pua ntawm cov ntawv thov.
Hloov kho Peroxide Curing - Txoj kev kho no ua rau kom qhov kub thiab txias ntawm FFKM mus rau 100 degree yam tsis muaj kev cuam tshuam tshuaj lom neeg. Qib no yog tsim nyog rau qhov chaw uas yuav tsum tau muaj qhov kub thiab txias.
Nitrile Cure (Triazine) - Txoj kev kho no muab qhov ua haujlwm siab tshaj plaws rau FFKM, txawm li cas los xij cov qib no tsis tuaj yeem siv nrog dej kub, chav dej lossis amines ntawm qhov kub siab.
Ib qho kev hloov pauv hauv ether pawg ntawm FFKM tuaj yeem muab FFKM nrog kev ua haujlwm kub qis dua. TRP muaj ob qhov ua tau zoo cryogenic FFKMs nrog lub peev xwm sib khi zoo li qub mus rau -45oC.
Ib daim ntawv teev npe tag nrho ntawm SJK FFKMs tuaj yeem pom nyob rau hauv cov nplooj ntawv cov ntaub ntawv ntawm lub vev xaib no.
