Dab tsi yogFFKM O-Rings
FFKM O-rings yog cov ntsaws ruaj ruaj uas ua los ntawm perfluoroelastomer compound uas muaj cov ntsiab lus fluorine ntau dua li FKM fluoroelastomers. Ua haujlwm zoo li ib qho O-ring kom kaw ob lossis ntau qhov chaw ntawm lub interface. Perfluoroelastomer FFKM O-ring feem ntau yog tsim nyog rau nws qhov kub thiab txias, qib tshuaj tiv thaiv hauv ntau qhov kev pabcuam tsis zoo, thiab kev pabcuam ntev.
FFKM O-Ring Khoom Description
Perfluoroelastomer (FFKM) yog ib qho polymer siab heev uas tiv taus cov pa plasma, tshuaj, cua sov, thiab chav. Cov khoom siv ultra-muaj zog carbon-fluorine bonding chemistry ua rau nws zoo tagnrho rau kev ua haujlwm siab O-rings. Vim nws cov khoom tshwj xeeb, FFKM muaj ntau daim ntawv thov hauv ntau qhov kev lag luam.
Perfluoroelastomer (FFKM) muab cov elasticity thiab yooj ntawm FKM nrog cov tshuaj tiv thaiv siab heev ntawm polytetrafluoroethylene (PTFE). Nws cov tshuaj tiv thaiv zoo heev yog vim nws cov qauv tshuaj, uas yog tsim los ntawm ultra-muaj zog carbon-fluorine bonds, muab peb cov khoom FFKM elastomer siab tshuaj, thermal, thiab oxidation kuj.
FFKM yog tsim los ntawm 72.5% fluorine nrog lub pob txha fluorinated tag nrho, uas yog qhov siab tshaj plaws ntawm fluorination tau thaum tseem khaws cov khoom elastomeric uas xav tau los tsim O-rings ua tau zoo.
Qhov zoo ntawm FFKM O-Ring
FFKM O-rings muaj kev tiv thaiv zoo rau kev puas tsuaj, kua qaub, tshuaj lom neeg feem ntau, cua sov, hluav taws xob, roj, thiab ozone raug. Cov O-rings no kuj yog huab cua thiab cua-resistant.
Cov khoom qis qis ntawm FFKM roj hmab nplhaib ua rau lawv xaiv zoo rau kev siv lub tshuab nqus tsev sealing. FFKM roj hmab O-rings yog tsis-flammable nyob rau hauv cov huab cua thiab nws tus kheej-extinguishing. Lawv muaj tsawg permeability thiab tawg decompression peev xwm.
Lawv kuj muab cov nplaim hluav taws zoo thiab cov khoom sib khi tab sis tsis tshua muaj kev tiv thaiv rau qhov txias txias dua li O-rings ua los ntawm lwm cov ntaub ntawv. Txawm li cas los xij, FFKM roj hmab O-rings tsis muaj lub zog muaj zog, ruaj khov, lossis tsim kua muag tsis muaj zog thiab tsis muaj zog tensile zoo.
- Tshuaj tiv thaiv
O-rings uas dhau los ntawm kev nthuav tawm tshuaj lom neeg tuaj yeem raug extruded los ntawm lub foob groove thiab ua rau lub foob tsis ua haujlwm. FFKM tiv taus ntau dua 1,800 chemicals, cov kuab tshuaj, thiab cov ntshav ntshav, suav nrog cov ntsiab lus nitric acid, sodium hydroxide, thiab ethylenediamine. FFKM O-rings yog qhov zoo tshaj plaws rau kev hnyav hnyav.
- Lub neej ntev
FFKM roj hmab O-rings tuaj yeem txo cov nqi los ntawm kev ncua lub sijhawm uas O-rings yuav tsum tau hloov. High-temperature kuj ua ke nrog cov tshuaj tiv thaiv yuav txo tau hardening thiab embrittlement. FFKM tseem muaj zog thiab ua haujlwm zoo txawm tias tom qab lub sijhawm ntev raug rau qhov kub thiab txias.
Ua ke nrog lawv cov txheej txheem compression qis, cov khoom zoo no tso cai rau O-rings los tuav lub foob kom ntev dua. Lub neej ntev kev pab cuam ntawm FFKM roj hmab O-rings txhais tau hais tias nquag hloov pauv, kho, thiab tshuaj xyuas txo cov nqi.
- Kev ceev faj tshwj xeeb
FFKM O-rings muaj thiab tuaj yeem tsim los rau cov xwm txheej tshwj xeeb. FDA-raws li cov khoom siv tuaj yeem siv rau hauv cov khoom noj, dej haus, thiab cov txheej txheem tshuaj.
Rau cov neeg uas xav tau kev ruaj ntseg sealing rau lub tshuab nqus tsev los yog UHV daim ntaub ntawv, huv chav tsev tsim FFKM O-rings muaj. Cov no yog tsim los rau cov xwm txheej uas yuav tsum tau muaj cov pa tawm tsawg thiab cov pa phem.
Kev siv
Ntau qhov kev lag luam siv FFKM O-rings hauv cov ntawv thov tseem ceeb uas qhov kev foob tsis raug txwv nruj heev. Cov kev lag luam no suav nrog kev ua tshuaj lom neeg, lub zog, semiconductor, tshuaj, roj thiab roj rov ua dua tshiab, aerospace thiab lwm yam lag luam.
- Hauv kev siv semiconductor, FFKM roj hmab O-rings pab tiv thaiv kev sib kis thaum muab tshuaj tiv thaiv thiab thermal stability. Txij li thaum FFKMs tiv taus qhov o thiab brittleness, cov txheej txheem siv tshuaj lom neeg kuj tuaj yeem ua kom zoo dua ntawm lawv.
- Hauv cov ntawv thov zaub mov thiab tshuaj, FFKM O-ring muab cov cua sov thiab tshuaj tiv thaiv thaum tiv thaiv kev sib kis.
- FFKM O-rings tuaj yeem tiv taus qhov kub li ntawm -15 degree F txog 608 degree F, ua rau lawv muaj kev xaiv zoo rau kev siv dav hlau. Qhov kub thiab txias tsis kam thiab kev kub siab ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev lag luam roj thiab roj.
