Yini i-ptfe hose |I-BESTEFLON

Uke wezwa ngempahla ye-PTFE kanyeIpayipi le-PTFE?Ake sibone ukuthi singayiphendula yini imibuzo ethile ngakho.

I-Polytetrafluoroethylene (i-polytetrafluoroethylene) ifushaniswa njenge-PTFE, evame ukwaziwa ngokuthi "inkosi yepulasitiki", futhi igama layo lokuhweba yi-Teflon.E-China, ngenxa yokuphimisela, i-"TEFLON" yaziwa nangokuthi i-Teflon, konke okuhunyushwa kwe-Teflon.I-Polytetrafluoroethylene yaziwa ngokuthi "inkosi yamapulasitiki", ubaba we-fluororesin Roy Planck 1936 inkampani yaseDuPont e-United States waqala ukutadisha esikhundleni seFreon.Baqoqa i-tetrafluoroethylene base beyigcina kumasilinda ukuze benze ucwaningo olulandelayo ngakusasa.Nokho, lapho kuvulwa ivalvu yokukhulula umfutho we-cylinder ngakusasa, alikho igesi elichichimayo.Babecabanga ukuthi ivuza, kodwa lapho bekala isilinda, bathola ukuthi isilinda sasingehli isisindo.Babona nge-cylinder bathola impushana emhlophe eningi, okuyi-polytetrafluoroethylene.Bathole ukuthi i-polytetrafluoroethylene inezinto ezinhle kakhulu futhi ingasetshenziswa njenge-anti melting sealing gasket yamabhomu e-athomu namagobolondo.Ngakho-ke, amasosha ase-US agcina ubuchwepheshe buyimfihlo phakathi neMpi Yezwe II.Kwaze kwaba sekupheleni kweMpi Yezwe II lapho yehliswa futhi yenziwa izimboni ngo-1946.Usesho Oluhlobene:Ipayipi lepayipi le-PTFE, Ipayipi likathayela le-PTFE

I-Polytetrafluoroethylene ingakhiwa ngokucindezelwa noma i-extrusion;kungenziwa futhi ukuhlakazeka kwamanzi ukuze kuhlanganiswe, ukufakwa esikhundleni noma i-fiber.I-Polytetrafluoroethylene (PTFE) isetshenziswa kabanzi ezimbonini zamandla e-athomu, ukuzivikela kuzwelonke, i-aerospace, i-electronics, ugesi, ubunjiniyela bamakhemikhali, imishini, izinsimbi, izinsimbi, ukwakhiwa, izindwangu, ukwelashwa kwendawo yensimbi, imithi, imithi, izindwangu, ukudla, i-metallurgy kanye izimboni zokuncibilikisa, njll., okwenza kube umkhiqizo ongabuyiseleki.

I-PTFE isifinyezo se-polytetrafluoroethylene - igama elide, kodwa isikhathi eside kufanele sisho ukuthi lihle!Igama lokuthengisa le-polytetrafluoroethylene igama elivame kakhulu le-polytetrafluoroethylene.

Kungani ipayipi le-polytetrafluoroethylene (PTFE) lisetshenziswa epayipini le-inkjet lephrinta ye-3D, ipayipi lokuphakela lomshini wekhofi, ipayipi lesistimu yokupholisa amanzi kanye nesistimu yamapayipi amabhuleki?

1) I-PTFE tube inokuqina kwamakhemikhali aphezulu futhi ingamelana nesenzo sawo wonke ama-acids aqinile, okuhlanganisa i-aqua regia, i-hydrofluoric acid, i-hydrochloric acid egxilile, i-nitric acid, i-fuming sulfuric acid, i-organic acid, isisekelo esiqinile, i-oxidant eqinile, i-ejenti yokunciphisa kanye ne-organic ehlukahlukene. izincibilikisi.Isetshenziswa kakhulu ekudluliseni uketshezi olunokhahlo oluhlukahlukene.

2) Ingasetshenziswa isikhathi eside ebangeni - 80 ℃ - + 280 ℃.Ingasebenza ekushiseni okuqandayo ngaphandle kwe-embrittlement futhi incibilike ekushiseni okuphezulu.

I-3) I-non-viscosity evelele kanye ne-anti viscosity ihle kakhulu, futhi udonga lwangaphakathi lwepayipi alunamatheli kuma-colloid namakhemikhali, ngakho-ke ngeke lwenze ungqimba olungcolile epayipini.

I-4) Ukusebenza okuhle kakhulu kokufakwa kukagesi I-Teflon iyimpahla engeyona i-polar enezici ezinhle ze-dielectric, ukumelana okuphezulu kanye nokungaguquki kwe-dielectric cishe kwe-2.0, okuyinto encane kunazo zonke izinto zokufakelwa kukagesi, futhi ukuguqulwa kwezinga lokushisa kanye nemvamisa kunomphumela omncane kuzo. .

I-5) Ukumelana nokuguga okuhle kakhulu nokumelana nemisebe, kungasetshenziswa ngaphandle isikhathi eside.

I-6) Ukuzinza okuhle kakhulu kwe-thermal, i-Teflon ine-incombustibility eyigugu kakhulu, inkomba yayo yomkhawulo we-oxygen ingaphezu kuka-95, ingancibilika kuphela emlilweni, ayikhiqizi amaconsi, futhi ingaba yi-carbonized kuphela.

7) Ukuthamba okuphezulu nokumelana nokugoba.

I-8) ukumelana nomswakama: ubuso befilimu ye-Teflon ayinawo amanzi namafutha, futhi akulula ukungcoliswa ngesisombululo ngesikhathi sokusebenza kokukhiqiza.Uma kukhona ukungcola okuncane okunamathelayo, kungasuswa ngokusula okulula.Inezinzuzo zesikhathi esifushane sokuphumula, ukonga ihora lomuntu kanye nokwenza ngcono ukusebenza kahle komsebenzi.

I-9) Ukumelana nokugqoka: ukumelana okuhle kakhulu kokugqoka ngaphansi komthwalo ophezulu.Ngaphansi komthwalo othile, inezinzuzo zokumelana nokugqoka nokunganamatheli.

Ipayipi le-Polytetrafluoroethylene linezinzuzo ezithile ngaphezu kwepayipi elivamile lerabha elinelayini.

Okokuqala, ipayipi le-polytetrafluoroethylene (PTFE) lisebenza njengesithiyo somoya, esinganamatheli ngesikhathi esifanayo sokumelana nokushisa okuphezulu, futhi singahlangabezana nezidingo zale mishini kanye nemishini yokusebenzisa amapayipi.

Okwesibili, ipayipi elilayishiwe le-PTFE linokumelana kwamakhemikhali okuphakeme kakhulu futhi lisekela uketshezi lwezimoto oluningi olungakwazi ukukunikeza irabha evamile, okuvame kakhulu ukuxutshwa kukaphethiloli okuqukethe i-ethanol.Ipayipi elivamile lenjoloba lizobola lapho libhekene nalolu hlobo lukaphethiloli futhi ekugcineni lonakele ngendlela yokuthi lingase liqale ukuvuza noma lijove uphethiloli, okuyingozi kakhulu.

Okwesithathu, i-hose ene-Teflon lined inokumelana nokushisa okuphezulu kakhulu - empeleni, izinga lokushisa elisebenzayo le-hose elithengiswa ngamashubhu e-PTFE liyi-65 ° C kuya ku- + 260 ° C. Ifaneleka kakhulu ukusetshenziswa kulawa madivayisi.

Okwesine, ipayipi le-Teflon tube Teflon hose inokucindezela okuphezulu kakhulu kokusebenza, futhi iqinisekisa ukuthi ungayisebenzisela zonke izinhlobo zezinhlelo zokusebenza zezimoto nezinduku ezishisayo.Usayizi we-An6 we-2500psi, usayizi we-an8 we-2000psi, ngisho nezinhlelo zokusebenza ezidinga kakhulu, ukucindezela kwayo kungaphezu kokwanele.

okunye?Yebo, empeleni - i-braided in hose yethu iqinisekisa impilo ende yesevisi nokubukeka okubukhali kokufakwa.Uma ukhetha insimbi engagqwali, inokubukeka okucijile futhi ikunikeza umuzwa wenduku eshisayo yobunjiniyela bamapayipi.Inayiloni emnyama uma ufuna ukubukeka okuthambile.Kodwa uyazi, inayiloni emnyama isenomugqa wensimbi engagqwali.Sidinga nje ukugqoka insimbi engagqwali enayiloni emnyama ukuze sithole ukubukeka okuhlukile.

Manje iyatholakala - Ipayipi le-Nylon Braided PTFE elinomugqa wehose ye-hot rod fuel usayizi an6.

Ngakho ipayipi le-PTFE lizwakala lilihle - yini engalungile ngalo?

Ngokuvamile, i-PTFE tube ingangena esikhundleni sezimo eziningi zeshubhu yenjoloba.Okuwukuphela kokubi kwe-PTFE tube ukuthi ukuguquguquka kwayo akukuhle njengalokho kweshubhu lerabha.Kodwa-ke, uchungechunge lwe-bellows lwe-PTFE tube lunokuguquguquka okuthile, okungaxazulula lesi sici esincane ngokuqhathaniswa.Kodwa kunezinto ezithile okudingeka uzazi.

I-1 - ye-PTFE hose enomugqa, udinga ukusebenzisa izifakelo ezifanele ezivela kumkhiqizi ofanayo ukuze uqinisekise ukuvaleka okuhle kokufakwayo.Njengoba uphawu lwenziwa nge-ferrule esikhundleni sokufaka epayipini lenjoloba, ukunakekelwa okwengeziwe kufanele kuthathwe lapho usikwa.Ukuze uthole ulwazi olwengeziwe, bheka imiyalelo yethu yokufaka.

I-radius egobayo ye-hose engu-2-ptfe iqine kakhulu ngoba kuzoba lula ukuyikhahlela uma yeqa okucacisiwe.Ukuze uthole ulwazi olwengeziwe, bheka isihloko sethu ku-bend radius.

Akunjalo ngepayipi le-hot rod fuel, kodwa uma uthenga nxazonke,Ipayipi le-PTFEngokuvamile kubiza kakhulu kune-hose ye-raber lined - intengo ye-hot rod fuel hose inhle kakhulu, ngokuvamile izikhathi eziningana intengo ye-rubber hose, futhi izohlala isikhathi eside.
