Kuyini ipayipi le-ptfe | BESTEFLON

Uke wezwa ngezinto ze-PTFE kanyeIpayipi le-PTFEAke sibone ukuthi singaphendula yini imibuzo ethile ngakho.

I-Polytetrafluoroethylene (i-polytetrafluoroethylene) ifushaniswe ngokuthi i-PTFE, eyaziwa kakhulu ngokuthi "inkosi yepulasitiki", futhi igama layo lokuhweba yi-Teflon. E-China, ngenxa yokuphinyiselwa kwayo, igama elithi "TEFLON" liyaziwa nangokuthi i-Teflon, konke okuwukuguqulwa kwe-Teflon. I-Polytetrafluoroethylene yaziwa nangokuthi "inkosi yamapulasitiki", uyise we-fluororesin Roy Planck 1936 DuPont company e-United States yaqala ukutadisha izinto ezithatha indawo ye-Freon. Baqoqa i-tetrafluoroethylene ethile bayigcina kumasilinda ukuze bayenze ukuhlolwa okulandelayo ngosuku olulandelayo. Kodwa-ke, lapho i-valve yokusiza ukucindezeleka kwesilinda ivulwa ngosuku olulandelayo, akukho gesi eyachichima. Babecabanga ukuthi kwakuvuza, kodwa lapho bekala isilinda, bathola ukuthi isilinda asizange sehlise isisindo. Babona isilinda bathola i-powder emhlophe eningi, okuyi-polytetrafluoroethylene. Bathola ukuthi i-polytetrafluoroethylene inezakhiwo ezinhle kakhulu futhi ingasetshenziswa njenge-gasket yokuvala elwa nokuncibilikisa amabhomu namagobolondo e-athomu. Ngakho-ke, amasosha ase-US agcina ubuchwepheshe buyimfihlo ngesikhathi seMpi Yezwe II. Kwaze kwaba sekupheleni kweMpi Yezwe II lapho yasuswa khona ohlwini lwezinkampani futhi yathuthukiswa ngo-1946. Ukusesha Okuhlobene:Ipayipi elinezintambo ze-PTFE, Ipayipi le-PTFE elihlanganisiwe

I-Polytetrafluoroethylene ingakhiwa ngokucindezelwa noma ngokukhipha; ingenziwa futhi ibe ukuhlakazwa kwamanzi ukuze kugqunywe, kufakwe noma kufakwe ifayibha. I-Polytetrafluoroethylene (PTFE) isetshenziswa kabanzi embonini yamandla e-athomu, ukuvikela izwe, izindiza, izinto zikagesi, ubunjiniyela bamakhemikhali, imishini, izinsimbi, izinsimbi, ukwakhiwa, indwangu, ukwelashwa kwendawo yensimbi, imithi, ezokwelapha, indwangu, ukudla, insimbi kanye nezimboni zokuncibilikisa, njll., okwenza kube umkhiqizo ongenakuphindwa.

I-PTFE yisifinyezo se-polytetrafluoroethylene - igama elide, kodwa elithi long kumele lisho ukuthi lihle! Igama lophawu lokuhweba le-polytetrafluoroethylene yigama elivame kakhulu le-polytetrafluoroethylene.

Kungani ipayipi le-polytetrafluoroethylene (PTFE) lisetshenziswa epayipini le-inkjet lephrinta ye-3D, epayipini lokufaka ikhofi lomshini, epayipini lesistimu yokupholisa amanzi kanye nasepayipini lamabhuleki?

1) Ishubhu le-PTFE linokuqina okuphezulu kwamakhemikhali futhi lingamelana nokusebenza kwawo wonke ama-asidi aqinile, okuhlanganisa i-aqua regia, i-hydrofluoric acid, i-hydrochloric acid egxilile, i-nitric acid, i-fuming sulfuric acid, i-organic acid, isisekelo esinamandla, i-oxidant enamandla, i-reducing agent kanye nezinyibilikisi ezahlukahlukene eziphilayo. Lisetshenziswa kabanzi ekudluliseni uketshezi oluhlukahlukene olunamandla.

2) Ingasetshenziswa isikhathi eside ebangeni eliphakathi kuka-80 ℃ - + 280 ℃. Ingasebenza emazingeni okushisa abandayo ngaphandle kokuqhekeka nokuncibilika emazingeni okushisa aphezulu.

3) Ukungabi nokuqina okuvelele kanye nokungaqinisi kuhle kakhulu, futhi udonga lwangaphakathi lwepayipi alunamatheli kuma-colloid namakhemikhali, ngakho ngeke lwakha ungqimba lokungcola epayipini.

4) Ukusebenza kahle kakhulu kokufakwa kokushisa kagesi I-Teflon iyinto engeyona i-polar kakhulu enezakhiwo ezinhle ze-dielectric, ukumelana okuphezulu kanye ne-dielectric constant engaba ngu-2.0, okuyiyona encane kunazo zonke izinto zokufakwa kokushisa kagesi, futhi ukushintsha kwezinga lokushisa kanye nemvamisa akunawo umthelela omkhulu kuzo.

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

6) Ukuqina okuhle kakhulu kokushisa, i-Teflon inamandla okungashi kakhulu, inkomba yayo yomkhawulo we-oxygen ingaphezu kwama-95, ingancibilika kuphela elangeni, ayikhiqizi amaconsi, futhi ingashiswa kuphela.

7) Ukuthamba okuphezulu nokumelana nokugoba.

8) ukumelana nomswakama: ubuso befilimu ye-Teflon abunamanzi namafutha, futhi akulula ukungcoliswa ngesisombululo ngesikhathi sokusebenza kokukhiqiza. Uma kunokungcola okuncane okunamathele, kungasuswa ngokusula okulula. Inezinzuzo zokungasebenzi isikhathi esifushane, ukonga ihora lomsebenzi kanye nokuthuthukisa ukusebenza kahle.

9) Ukumelana nokuguguleka: ukumelana okuhle kakhulu nokuguguleka ngaphansi komthwalo omkhulu. Ngaphansi komthwalo othile, inezinzuzo zokumelana nokuguguleka kanye nokunganamatheli.

Ipayipi le-polytetrafluoroethylene linezinzuzo ezithile kunepayipi elijwayelekile elinomugqa wezambatho.

Okokuqala, ipayipi le-polytetrafluoroethylene (PTFE) lisebenza njengesivikelo somusi, esinganamatheli ngesikhathi esifanayo sokumelana nokushisa okuphezulu, futhi lingahlangabezana nezidingo zale mishini nemishini yokusebenzisa amapayipi.

Okwesibili, ipayipi eline-PTFE linokumelana okuphezulu kwamakhemikhali futhi lisekela uhla lweziketshezi zezimoto ezinganikezwa irabha evamile, okuvame kakhulu yizingxube zikaphethiloli eziqukethe i-ethanol. Ipayipi elijwayelekile lerabha lizobola uma livezwa kulolu hlobo lukaphethiloli futhi ekugcineni lonakale kuze kube yilapho lingase liqale ukuvuza noma ukufaka uphethiloli, okuyingozi kakhulu.

Okwesithathu, ipayipi eline-Teflon linokumelana nokushisa okuphezulu kakhulu - empeleni, izinga lokushisa lokusebenza lepayipi elithengiswa ngamashubhu e-PTFE liphakathi kuka-65° C kuya ku-+ 260° C. Lifaneleka kakhulu ukusetshenziswa kulawa madivayisi.

Okwesine, ithubhu le-Teflon ipayipi le-Teflon linomfutho ophezulu kakhulu wokusebenza, futhi liqinisekisa ukuthi ungalisebenzisa kuzo zonke izinhlobo zezicelo zezimoto kanye ne-hot rod. Usayizi we-An6 we-2500psi, usayizi we-an8 we-2000psi, ngisho nezinhlelo zokusebenza ezidinga kakhulu, umfutho walo ungaphezu kokwanele.

okunye? Yebo, empeleni - okulukiwe epayipini lethu kuqinisekisa impilo ende yesevisi kanye nokubukeka okubukhali kokufakwa. Uma ukhetha insimbi engagqwali, inokubukeka okubukhali futhi ikunikeza umuzwa wenduku eshisayo yobungcweti bobunjiniyela bepayipi. I-nylon emnyama uma ufuna ukubukeka okuthambile. Kodwa uyazi, i-nylon emnyama isenayo i-lining yensimbi engagqwali. Sidinga nje ukumboza insimbi engagqwali nge-nylon emnyama ukuze sithole ukubukeka okuhlukile.

Manje isiyatholakala - ipayipi eliluhlaza okwesibhakabhaka nelibomvu le-Nylon Braided PTFE eline-hot rod fuel hose elinosayizi we-an6.

Ngakho-ke ipayipi le-PTFE lizwakala kahle - yini inkinga ngalo?

Ngokuvamile, ithubhu le-PTFE lingathatha indawo yezimo eziningi zethubhu yerabha. Okuwukuphela kwenkinga yethubhu le-PTFE ukuthi ukuguquguquka kwalo akukuhle njengokwethubhu yerabha. Kodwa-ke, uchungechunge lwethubhu le-PTFE olunezinzwa ezithile lunokuguquguquka okuthile, okungaxazulula lesi sici esincane ngokuqhathaniswa. Kodwa kunezinto ezithile okudingeka uzazi.

1 - ngepayipi elinezintambo ze-PTFE, udinga ukusebenzisa izihlanganisi ezifanele ezivela kumkhiqizi ofanayo ukuqinisekisa ukuvalwa okuhle kwezihlanganisi. Njengoba isihlanganisi senziwe nge-ferrule esikhundleni se-insert epayipini lerabha, kudingeka kuqashelwe kakhulu lapho usika. Ukuze uthole ulwazi olwengeziwe, bheka imiyalelo yethu yokufaka.

Irediyasi yokugoba yepayipi le-2-ptfe iqinile kakhulu ngoba kuzoba lula ukuyigoba uma idlula isilinganiso. Ukuze uthole ulwazi olwengeziwe, bheka isihloko sethu mayelana nerediyasi yokugoba.

Akunjalo ngepayipi likaphethiloli elishisayo, kodwa uma ubhekabheka,Ipayipi le-PTFEngokuvamile kubiza kakhulu kunepayipi elifakwe irabha - intengo yepayipi likaphethiloli elishisayo inhle kakhulu, imvamisa intengo iphindwe kaningana kunepayipi lerabha, futhi izohlala isikhathi eside.
