Iindaba - Irabha ye-FKM vs PTFE: Yeyiphi eyona mathiriyeli yefluorinated |BESTEFLON

Irabha yeFluorine (FKM) yi-thermosetting elastomer, ngelixa i-polytetrafluoroethylene (PTFE) i-thermoplastic.Zombini zizixhobo ezifunxa, zijikelezwe ziiathom zefluorine ziiathom zekhabhoni, ezizenza zikwazi ukumelana neekhemikhali ngendlela emangalisayo.Kweli nqaku, isisombululo se-polymer ye-TRP sithelekisa izinto ezimbini phakathi kwe-FKM kunyePTFEukumisela ukuba yeyiphi imathiriyeli yokugqibela enefluorinated kwaye ukhethe eyokugqibelaPTFE umenzi wethumbu

Izibonelelo zerabha ye-FKM kunye ne-PTFE

Imvelaphi:

I-FKM: Iinqwelomoya ngexesha leMfazwe yesibini yeHlabathi zazithwaxwa kukuvuza kwezitywina ze-nitrile, ezazingenawo ubushushu obuphantsi obufunekayo kwizicelo ezahlukeneyo.I-inertness yekhemikhali ye-fluorocarbon bond ithetha ukuba i-elastomers ene-fluorinated, okanye i-fluoroelastomers, sisigqibo sendalo.Ke irabha yeFKM yaqala ukuthengiswa ngo-1948

I-PTFE: Ngo-1938, isazinzulu saseDuPont uRoy Plancott wafumanisa i-polytetrafluoroethylene ngengozi.UPlunkett wenza ulinge ngezikhenkcezisi waza wazigcina kwiisilinda.Okwamothusayo kukuba, ezi gesi zadityaniswa, zishiya ngasemva incindi emhlophe, engadibaniyo nemichiza yaye inokumelana nobushushu obugqithiseleyo.I-DuPont yabhalisa uphawu lokuqala lwe-PTFE materials-ptfe ngo-1945

Isigwebo: Ukuphuhliswa kwe-PTFE yinto ehambelana nekamva elinomdla, elikhokelela ekuzalweni kwezinto ezingaqhelekanga.Nangona kunjalo, into enomtsalane ngokulinganayo, irabha ye-FKM, yayiyimfuneko ngokupheleleyo kwiminyaka yemfazwe.Ngesi sizathu, igalelo lembali le-FKM fluoroelastomer lithetha ukuba ngcono kancinci kulo mjikelo wokhuphiswano.

Iinkcazelo ngeempawu:

Irabha ye-FKM: Irabha ye-FKM iqulethe iibhondi ezomeleleyo ze-carbon-fluorine, iyenza ukuba ibe yimichiza ephezulu, ikwazi ukumelana nobushushu kunye ne-oxidation-resistant.I-FKM iqulethe inani elahlukileyo leebhondi ze-carbon-hydrogen (unxibelelwano olunobushushu obubuthathaka kunye nokumelana neekhemikhali), kodwa isenamandla okumelana neekhemikhali kunezinye ii-elastomers ezininzi.

I-PTFE: I-Polytetrafluoroethylene yenziwe ngekhonkco leathom zekhabhoni, ezineathom ezimbini zefluorine kwiathom yekhabhoni nganye.Ezi athom zefluorine zijikeleze ikhonkco lekhabhoni ukwenza imolekyuli eshinyeneyo enebhondi yecarbon-fluorine eyomeleleyo kunye nesakhiwo sepolymer, okwenza i-PTFE inert kwimichiza emininzi.

Isigqibo: Ngokusekwe ngokuthe ngqo kukwakheka kweekhemikhali, i-PTFE ayinazo iibhondi ze-carbon-hydrogen, nto leyo eyenza ukuba ingasebenzi ngokwekhemikhali ngaphezu kwe-FKM (nangona i-FKM isaxhathisa ngokumangalisayo kwikhemikhali).Ngesi sizathu, i-PTFE sisithunzi nje se-FKM kulo mjikelo

Izinto eziluncedo:

FKM:

Uluhlu olubanzi lobushushu (-45°C-204°C)

Ukuchasana kweekhemikhali okugqwesileyo
