PTFE Coated O-Rings Applications
I-Aegis, i-Aflas, i-Butyl, i-Fluorosilicone, i-Hypalon okanye nayiphi na i-compound isicelo sakho esithile esinokuyifuna.I-O-Rings ezicatyiswe kunye ne-Ecapsulated yenye inketho kwakhona:
- I-Coated or Encapsulated - I-Coated O-Rings ifakwe kwi-PTFE, kunye ne-coating ebambelele kwi-O-Ring (ngokuqhelekileyo i-Silicone okanye i-Viton okanye i-NBR).I-O-Rings efakwe kwi-O-Ring (ngokuqhelekileyo i-Silicone okanye i-Viton) ehlanganiswe ne-PTFE ityhubhu.I-PTFE yokwambathisa ye-O-Rings yeyona nto ifanelekileyo yokugquma i-low-friction apho ukuguquguquka kokusebenza kuyingqwalasela enkulu.I-O-Ring efihliweyo iziphatha njengolwelo oluphezulu lwe-viscous, naluphi na uxinzelelo kwi-seal luhanjiswa kuwo onke amacala.Ii-O-Rings ezicatyiswe ziyafumaneka kwimibala ebanzi.
- Iikhompawundi ezikhethekileyo zemathiriyeli - Ukuba unemfuno yekhompawundi ethile engeyiyo imigangatho yeshishini eliqhelekileyo, sinokusebenza kunye nabavelisi ukuvelisa loo ngqungquthela ethile ukuhlangabezana neemfuno zakho.
- I-Mil-Spec, i-Mil-Std okanye i-Milspecs ngumgangatho wokukhusela wase-United States osetyenziselwa ukufezekisa iinjongo zokulinganisa yiSebe lezoKhuselo lase-US.IiRocket Seals zinokuvelisa nayiphi na i-Mil-Spec ngokusebenzisa inethiwekhi yethu enkulu yababoneleli abathembekileyo.
- Izinto zokutya ze-FDA, ukutyunjwa kwamanye amazwe, i-USP, i-KTW, i-DVGW, i-BAM, i-WRAS (i-WRC), i-NSF, i-Underwriters Laboratories (UL), i-Aerospace (AMS) kunye ne-Mil-Spec - i-Rocket inamava kunye nokuhlangabezana neemfuno zakho kuyo yonke imigangatho yoshishino.
ungakhetha umbala olandelayo okanye omnye umbala ongaphezulu.
Yaziwa ngcono ngegama lebhrendi iTeflon, i-polytetrafluoroethylene (PTFE) ibonelela ngomphezulu ongasimi kwi-cookware, ipolishi yeenzipho, izixhobo zokulungisa iinwele, unyango lwelaphu/ikhaphethi, kunye neebhleyidi zokucima i-windshield.Nangona kunjalo, abavelisi babona iinzuzo ezongeziweyo ekusebenziseni i-PTFE njengendlela yokwenza umgangatho we-O-rings.O-amakhonkcoeyakhiwe kusetyenziswa i-PTFE ibonelela ngokugqithisileyo kwe-thermal kunye neekhemikhali zokugquma, kwaye banokuxhathisa ukukhuhla kunye namanzi ngokunjalo.
I-PTFE KUNYE NE-TEFLON
Nangona behluke kwi-branding, i-PTFE kunye neTeflon babelana ngemvelaphi efanayo kunye neepropati.
PTFE
I-PTFE yipolima yokwenziwa ephuma kwiqhina lekhemikhali phakathi kwekhabhoni kunye nefluorine, ithatha ithuba lokuqhelana neeradicals zasimahla zokupholisa ngetetrafluoroethylene.Esi sixhobo safunyanwa ngempazamo ngo-1938, xa usokhemesti waseDuPont uRoy J. Plunkett wazama ukwenza uhlobo olutsha lwesikhenkcisi, waza waxuba ezi mathiriyeli ngaphandle kokwazi ukusabela okuya kubangela.
I-TEFLON
I-Kinetic Chemicals, inkampani yobambiswano phakathi kweDuPont kunye neGeneral Motors, iphawulwe nge-PTFE phantsi kwegama le-brand Teflon ngo-1945. Eyona nto, iTeflon yi-PTFE.Nangona kunjalo, i-PTFE ikwafumaneka phantsi koluhlu lwamanye amagama ebhrendi, anje:
- I-Daikin-Polyflon
- Fluon
- Dyneon
IIPROPATI
Iipropati ezininzi zahlula i-PTFE kwezinye izinto, kuquka:
- I-coefficient yokukhuhlana ephantsi: I-PTFE ine-coefficient yesithathu esezantsi yokukhuhlana kwayo nayiphi na into eyaziwa ngumntu, okuthetha ukuba yinyani.
- Imisebenzi kumaqondo obushushu agqithisileyo: Ilinganiswe kwi-600 K, i-PTFE inyibilika kwi-327ºC okanye i-620ºF, kwaye isebenza kakuhle kumaqondo obushushu asezantsi njenge -268ºC okanye −450ºF.
- Ixhathisa amanzi: Amaso amanzi phezulu kumphezulu we-PTFE, okuthetha ukuba imiphezulu enyangwa ngolu lwazi imelana ne-oxidation.
- Nonreactive: PTFE ayisebenzi ngobuninzi bezinto ezonakalisayo, iyenza ilungele ukusetyenziswa kwimibhobho, iivalvu, itywina, kunye ne-O-rings.
UDIDI LOBUSHUSHU ELIPHEZULU lwe-PTFE
Uluhlu lobushushu (-1,000F ukuya +4,000F), nonreactivity, ukumelana kwamanzi, kunye neempawu eziphantsi ukukhuhlana kwe-PTFE kwenza kube yinto efanelekileyo yokwakha ama-O-rings ukuze asetyenziswe kwiintlobo ezahlukeneyo zezicelo.Ezi propati zenza i-PTFE O-rings ibe lukhetho olufanelekileyo kwizicelo ezixhathisa imozulu kunye nezicelo ezibandakanya umbane kunye nokugqunyelelwa kwe-thermal.
Ngenxa yobuninzi babo,PTFE O-amakhonkco"Azinyibiliki" - endaweni yoko, ziyaxinzelelwa kwaye zixinzelelwe ukunika ukumila okuyimfuneko.
TEFLON/PTFE SEALS
O-amakhonkcoezenziwe PTFE zikho kwiintlobo ngeentlobo izicelo zoshishino ezifuna amatywina anokumelana nobunzima.I-PTFE O-rings ibonakala kwizicelo ezininzi ezivezwe kwezi zinto zilandelayo zomngcipheko:
Izicelo eziphezulu | Ubuthathaka boomatshini |
