PTFE: "King of fluoropolymers" nrog innate Dej Peedellency
PTFE lub hydrophobicity tsis tiav los ntawm post - kev; Nws cov tshuaj tua dej yog qhov xam ntawm qib molecular. Qhov no feem ntau yog vim nws cov qauv siv lub cev lossis tshuaj lom neeg:
Cov fluorocarbon muaj zog fluorocaron
Qhov tseem ceeb ntawm PTFE molecule yog muaj cov pa roj carbon atoms puag ncig los ntawm lub hnab ntawv me me ntawm electronegative attronefine atoms. Cov qauv no tsim kom muaj qhov chaw du nrog lub zog qis thiab cov tshuaj lom neeg hauv inertness.
Zoo heev Thermal stability thiab tshuaj lom in inertness
PTFE tswj tau kev ua tau ruaj khov hla ntau ({20℃rau 260 degree) thiab nyob rau hauv cov peev xwm hnyav-deb ntawm lub peev xwm ntawm cov polymers.
Intrinsic hydrophobicity thiab oleophlicity
Nws tsis tshua muaj hluav taws xob hnyav ua rau nws nyuaj rau ob qho tib si, ua rau lub kaum sab xis loj nkag mus thiab ua rau cov kua txhawm rau txhawm rau txhawm rau yooj yim.
Ib qho chaw ntawm hydrophobicity: molecular qauv thiab micropore morphology
Hom CNC Machininghe hydrophobicity ntawm PTFE cov dab tsi tsis yog vim ib qho kev cuam tshuam tab sis theej lub synergistic nyhuv ntawm lawv cov yam ntxwv molecular thiab lub cev qauv:
"Tiv thaiv kev tiv thaiv" ntawm qib molecular
Lub siab ua lub zog ntawm c- f fluorine atoms tiv thaiv cov roj ntsha ua kom muaj txiaj ntsig los tiv thaiv cov dej sib xyaw ua ke, tiv thaiv cov dej sib xyaw kom tsis txhob muaj cov dej ntws los ntawm kev ua kom zoo nkauj.
Ib tug "kev tiv thaiv txheej txheem" ntawm qib microscopic
PTFE WAIRBranes, tsim los ntawm tus txheej txheem ncab tshwj xeeb, muaj cov lej tsis muaj ntau Cov pores no tsis tsuas yog pom kev ua tau zoo, tab sis lawv cov microstructure ntxiv nce cov dej sib cuag, ua tiav ib qho nyhuv superhydrophobic nyhuv.
Qhov no dual - viewing mechanism pab tauPTFE HEPAakuvfqhuab qhiasTxhawm rau kom muaj huab cua tsis txaus ntseeg, nyob hauv dej hiav txwv mat, thiab txawm tias thaum lub sijhawm me me, tsis muaj kev cuam tshuam kev ua yeeb yam.
Daim Ntawv Thov Kev Pab Cuam
Kev tiv thaiv muaj kev tiv thaiv
Hauv kev tso tawm cov tshuab hluav taws xob thiab cov tshuaj tiv thaiv cov tshuaj lom neeg, PTFE hydround thiab fermentation lom, thiab ua kom muaj kev lom zem.
Precision Electronics Raug
Kev sib dhos thiab cov kab ke Microelectronic yog qhov tsis tshua pom zoo rau cov av noo.PTFE HEPAakuvfqhuab qhiasXyuas kom muaj airflow qhuav, tiv thaiv kev oxidation thiab luv luv ntawm Circuit Court laug cam, thiab kev tswj hwm cov hluav taws xob zoo li qub.
Kev Tiv Thaiv Kho Mob thiab Khoom Siv
PTFE tsis yog tsuas yog cov tub ntxhais lub tshuab lim no zoo li qub nyob rau hauv N95 lub khob ntsej muag, nws hydrophobicity ua kom muaj kev tiv thaiv zoo sib xws txawm tias muaj kev tiv thaiv noo noo txawm tias muaj kev tiv thaiv noo noo. Hauv kev ua yeeb yam thiab tshuaj loog pleev kob ntawm cov cua sov los ntawm txhaws cov pa, txhim kho cov cuab yeej kev nyab xeeb thiab kev pabcuam kev nyab xeeb.
Kev tiv thaiv ib puag ncig thiab lub zog
Nyob rau hauv kev tso siab tshuaj xyuas cov ntaub pua chaw pov tseg thiab tshuaj lom neeg siv roj kom zoo, PTFE HEPAakuvfqhuab qhiasCais cov dej txia dej thiab cov kua qaub los ntawm cov roj uas tsis muaj roj, tiv thaiv cov twj paj nruag prealisTical los ntawm kev puas tsuaj.
