Incazelo emfushane:

I-BD SEALS ihlinzeka ngezixazululo eziningi ze-O-ring, i-gasket, & nengxenye ebunjwe ngokwezifiso, okuhlanganisa: PTFE (Teflon), Paralyne (N, C, D kanye ne-HT),

I-HNBR, i-FKM, i-FPM, i-VITON, i-NBR, i-HNBR Silicone, i-Moly, ijazi le-plasma, nezinye izinketho zokuhlanganisa okukhethekile.Ukukhetha kokunamathela kuncike kakhulu ekusetshenzisweni nasembonini.

PTFE Coated O-Rings Izicelo

I-Aegis, i-Aflas, i-Butyl, i-Fluorosilicone, i-Hypalon nanoma iyiphi inhlanganisela uhlelo lwakho oluqondile olungase ludinge.Ama-O-Rings Ahlanganisiwe futhi Ahlanganisiwe angenye inketho futhi:

Ahlanganiswe noma Ahlanganisiwe - Ama-O-Rings ahlanganiswe yi-PTFE, okunamathelayo okunamathela ku-O-Ring (imvamisa i-Silicone noma i-Viton noma i-NBR).I-O-Rings Ehlanganisiwe iyi-O-Ring (imvamisa i-Silicone noma i-Viton) embozwe ngeshubhu le-PTFE.Ukufakwa kwe-PTFE kwe-O-Rings kuwukunamathela okufanelekile kokungqubuzana okuphansi lapho ukuguquguquka kokusebenza kuwukucatshangelwa okukhulu.I-O-Ring evalekile iziphatha njengoketshezi olubonakalayo oluphezulu, noma yikuphi ukucindezela esigxivizweni kudluliselwa kuzo zonke izinhlangothi.Ama-O-Rings ahlanganisiwe atholakala ngemibala eminingi ehlukahlukene.
Izinhlanganisela ezikhethekile zezinto zokwakha - Uma unesidingo senhlanganisela ethile engeyona indinganiso evamile yemboni, singasebenzisana nabakhiqizi ukukhiqiza leyo nhlanganisela ethize ukuze ihlangabezane nezidingo zakho.
I-Mil-Spec, i-Mil-Std noma i-Milspecs izinga lokuzivikela lase-United States elisetshenziselwa ukufeza izinjongo zokumiswa nguMnyango Wezokuvikela wase-US.Ama-Rocket Seals angathola noma iyiphi i-Mil-Spec ngokusebenzisa inethiwekhi yethu enkulu yabahlinzeki abahlonishwayo.
Izinto zebanga lokudla ze-FDA, amagama angaphandle, i-USP, i-KTW, i-DVGW, i-BAM, i-WRAS (WRC), i-NSF, i-Underwriters Laboratories (UL), i-Aerospace (AMS) kanye ne-Mil-Spec - I-Rocket inolwazi lokuhlangabezana nezidingo zakho kuwo wonke amazinga omkhakha.

ungakhetha umbala olandelayo noma omunye umbala owengeziwe.

Eyaziwa kangcono ngegama lomkhiqizo i-Teflon, i-polytetrafluoroethylene (PTFE) inikeza indawo engaqinile ku-cookware, i-nail polish, amathuluzi okwenza izinwele, ukwelashwa kwendwangu/ukhaphethi, nama-wiper blades.Kodwa-ke, abakhiqizi babona izinzuzo ezengeziwe ngokusebenzisa i-PTFE njengendlela yokwenza ama-O-rings ekhwalithi.O-izindandathoeyakhelwe kusetshenziswa i-PTFE inikeza ukufakwa okushisayo okuphakeme namakhemikhali, futhi ingamelana nokungqubuzana namanzi futhi.

I-PTFE VERSUS TEFLON

Nakuba zihluka ngokufaka uphawu, i-PTFE ne-Teflon babelana ngomsuka nezici ezifanayo.

I-PTFE

I-PTFE i-polymer yokwenziwa esuselwe ekuhlanganeni kwamakhemikhali phakathi kwekhabhoni ne-fluorine, isizakala ngokuthambekela kwama-radicals mahhala ukupholisa nge-tetrafluoroethylene.Le nto yatholwa ngephutha ngo-1938, lapho usokhemisi waseDuPont u-Roy J. Plunkett ezama ukwakha uhlobo olusha lwesiqandisi, futhi wahlanganisa lezi zinto ngaphandle kokwazi ukusabela okwakuzobangelwa.

I-TEFLON

I-Kinetic Chemicals, inkampani ebambisene phakathi kwe-DuPont ne-General Motors, ebizwa nge-PTFE ngaphansi kwegama lomkhiqizo i-Teflon ngo-1945. Ngamafuphi, i-Teflon yi-PTFE.Kodwa-ke, i-PTFE iyatholakala futhi ngaphansi kwezinhlobonhlobo zamanye amagama emikhiqizo, njenge:

I-Daikin-Polyflon
I-Fluon
Dyneon

IZIMPAHLA

Izakhiwo eziningana zihlukanisa i-PTFE kwezinye izinto, okuhlanganisa:

I-low friction coefficient: I-PTFE ine-coefficient yesithathu ephansi yokungqubuzana kwanoma iyiphi into eyaziwa ngumuntu, okusho ukuthi ngempela
Imisebenzi emazingeni okushisa okweqile: Ilinganiselwe ku-600 K, i-PTFE inyibilika ku-327ºC noma ku-620ºF, futhi isebenza kahle emazingeni okushisa aphansi njengo-−268ºC noma −450ºF.
Imelana namanzi: Amanzi enza ubuhlalu phezulu phezu kwe-PTFE, okusho ukuthi izindawo eziphathwayo ngale nto zimelana ne-oxidation.
Ayisebenzi: I-PTFE ayiphenduli ngobuningi bezinto ezonakalisayo, iyenze ibe ilungele ukusetshenziswa kumapayipi, amavalvu, ama-seal, nama-O-rings.

I-PTFE'S ELIPHEZULU LWETEMPERATURE RANGE

Izinga lokushisa (-1,000F kuya ku-+4,000F), ukungenzi lutho, ukumelana namanzi, kanye nezakhiwo eziphansi zokungqubuzana kwe-PTFE kukwenza kube impahla ekahle yokwakha ama-O-rings ukuze asetshenziswe kuzinhlelo zokusebenza ezihlukahlukene.Lezi zakhiwo zenza i-PTFE O-rings ibe yinketho ekahle yezinhlelo zokusebenza ezimelana nesimo sezulu kanye nezinhlelo zokusebenza ezibandakanya ugesi nokushisa okushisayo.

Ngenxa yobuningi babo,I-PTFE O-rings“Azincibilikisiwe”— esikhundleni salokho, ziyacindezelwa futhi zifakwe emanzini ukuze zinikeze isimo esidingekayo.

I-TEFLON/PTFE SEALS

O-izindandathoezenziwe nge-PTFE zikhona ezinhlobonhlobo zezicelo zezimboni ezidinga izimpawu ezingamelana nobunzima.I-PTFE O-rings ivela ezinhlelweni eziningi ezivezwe kuzinto ezilandelayo eziyingozi:

Izinhlelo zokusebenza eziphezulu	Ubuthakathaka Bemishini
Ngaphandle Izinto zokugcoba Amakhabhoni Ama-Acids Ama-alkali Izihlanzi Utshwala Ama-ketones I-Steam Iziqandisi	High Vacuum Seals I-Low-Compress Vacuum Sealing Flanges I-Super-Heated Steam
