Perfluoroelastomer (FFKM) O-Izangqa
IINKCUKACHA ZEMVELISO
I-Perfluoroelastomer (i-FFKM) i-O-rings imele incopho yobuchwephesha bokutywinwa, inika umsebenzi ongenakulinganiswa kwiindawo ezifunwa kakhulu zoshishino. Ezi zindandatho ze-O zenziwe ngebhondi ye-carbon-fluorine, ebanika i-thermal ekhethekileyo, i-oxidative, kunye nokuzinza kweekhemikhali. Olu lwakhiwo olulodwa lweemolekyuli luqinisekisa ukuba i-FFKM O-rings inokumelana neendaba ezinobundlobongela, okwenza ukuba zithembeke kakhulu kuzo zombini izicelo eziguqukayo kunye ne-static. Iyakwazi ukuxhathisa umhlwa kwizinto zekhemikhali ezingaphezu kwe-1,600 ezinjengeeasidi ezomeleleyo, iialkali ezomeleleyo, izinyibilikisi eziphilayo, ubushushu obuphezulu bomphunga, ii-ethers, iiketones, izinto ezipholileyo, iikhompawundi ezinenitrogen, iihydrocarbons, iialcohols, aldehydes, furans, kunye neekhompawundi zeeamino.
Iimpawu eziphambili zeFFKM O-Rings
Nangona zombini i-perfluorocarbon (FFKM) kunye ne-fluorocarbon (FKM) i-O-rings zisetyenziselwa ukutywinwa kwezicelo, zihluke kakhulu ekubunjweni kweekhemikhali kunye nokukwazi ukusebenza.
Ukubunjwa kwemichiza: Izangqa ze-FKM O-zenziwe ngemathiriyeli ye-fluorocarbon kwaye zilungele ukusetyenziswa ngokubanzi ukuya kuma-400°F (204°C). Banikezela ukuxhathisa okulungileyo kwiintlobo zeekhemikhali kunye nolwelo kodwa abanako ukumelana neemeko ezigqithisileyo ngokufanelekileyo njenge-FFKM.
Ukusebenza okugqithisileyo kokusiNgqongileyo: I-FFKM O-izangqa ziyilelwe iimeko ezingqongileyo ezigqithisileyo. Ukukwazi kwabo ukusebenza kumaqondo obushushu aphezulu kwaye baxhathise uluhlu olubanzi lweekhemikhali kubenza babe lolona khetho lukhethwayo lwezicelo kumashishini afana ne-aerospace, ukusetyenzwa kweekhemikhali, kunye nokuveliswa kwe-semiconductor.
Ukuqwalaselwa kweendleko: Izinto ze-FFKM zibiza kakhulu kune-FKM ngenxa yokusebenza kwazo okuphezulu kunye neenkqubo ezikhethekileyo zokuvelisa. Nangona kunjalo, utyalo-mali kwi-FFKM O-rings lufanelekile ngokukwazi kwabo ukukhusela ukungaphumeleli kwentlekele kunye nokuqinisekisa ukuthembeka kwexesha elide kwizicelo ezibalulekileyo.
I-FFKM vs. FKM: Ukuqonda iiyantlukwano
Indlela yokutywina
IRingi ye-ED isebenza kumgaqo wokunyanzeliswa koomatshini kunye noxinzelelo lwamanzi. Xa ifakwe phakathi kweeflange ezimbini zokufakelwa kwe-hydraulic, iprofayili ekhethekileyo ye-angle ye-ED Ring ihambelana neendawo zokukhwelana, idala itywina lokuqala. Njengoko uxinzelelo lwe-hydraulic fluid lusanda ngaphakathi kwenkqubo, uxinzelelo lolwelo lusebenza kwiRingi ye-ED, ibangela ukuba yande ngokusasazeka. Oku kwandiswa kwandisa uxinzelelo loqhagamshelwano phakathi kwe-ED Ring kunye ne-flange surfaces, ukuphucula ngakumbi isitywina kunye nokuhlawulela nakuphi na ukungahambi kakuhle kwendawo okanye ukungahambi kakuhle okuncinci.
Ukuzixhasa kunye nokuzilungisa
Enye yeenzuzo eziphambili zeRingi ye-ED kukuzingca kunye namandla okuzilungisa. Uyilo lweringi luqinisekisa ukuba luhlala luzinze phakathi kodibaniso ngexesha lofakelo kunye nokusebenza. Olu phawu lokuzimela lunceda ukugcina uxinzelelo loqhagamshelwano olungaguqukiyo kuwo wonke umphezulu wokutywina, ukunciphisa umngcipheko wokuvuza ngenxa yokungahambi kakuhle. Ukongezelela, ukukwazi kwe-ED Ring ukulungelelanisa kwiingcinezelo ezahlukeneyo kunye namaqondo okushisa aqinisekisa ukuthembeka kwexesha elide kunye nokusebenza okungaguqukiyo, nakwiimeko zokusebenza ezinamandla.
Ukutywinwa okunamandla phantsi koxinzelelo
Kwiinkqubo zoxinzelelo oluphezulu lwe-hydraulic, ukukwazi kwe-ED Ring ukutywina ngokuguquguqukayo phantsi koxinzelelo kubalulekile. Njengoko uxinzelelo lolwelo lunyuka, iipropathi zezinto ze-ED Ring ziyivumela ukuba icinezele kwaye yandise, igcine itywina eliqinileyo ngaphandle kokonakala okanye ukuphuma. Esi sixhobo sokutywina esiguquguqukayo siqinisekisa ukuba iRingi ye-ED ihlala isebenza kubo bonke ubomi bokusebenza kwenkqubo ye-hydraulic, ukuthintela ukuvuza kwamanzi kunye nokugcina ukusebenza kakuhle kwenkqubo.
