Yini izindwangu ezihlanganisiwe ze-PTFE?

Izindwangu ezihlanganisiwe ze-PTFE , ezaziwa nangokuthi izindwangu ezihlanganisiwe zeTeflon noma indwangu ehlanganisiwe ye-PTFE, yizinto zokusebenza okuphezulu ezihlanganisa izindawo ezihlukile ze-polytetrafluoroethlene (PTFE) ngamandla ahlukahlukene wendwangu. Lezi zinto ezintsha zenziwa ngokufaka ungqimba lwe-PTFE endwangu eyisisekelo, ngokujwayelekile i-fiberglass, okuholela kwinhlanganisela evuthayo yokushisa, ukuqina kwamakhemikhali, kanye nezakhiwo ezingezona ezinamathele. Izindwangu ezihlanganisiwe ze-PTFE ezihlanganisiwe ezindaweni ezifunwayo lapho izinto ezijwayelekile ziwela zifushane, zinikeza ukuqina okuphezulu, isimo sezulu, kanye nokuhlanza kalula. Inhlanganisela yabo eyingqayizivele yezimfanelo iyenza iphuthunyiswe kwizimboni eziningi, kusuka e-aerospace kanye nezimoto ekusebenzeni kokudla kanye nezicelo zokwakha.

Ukwakheka kanye nenqubo yokukhiqiza yezindwangu ezihlanganisiwe zePTFE

Ukukhetha kwendwangu

Isisekelo sezindwangu ezihlanganisiwe zePTFE zilele ekukhetheni ngokucophelela kwezinto zesisekelo. I-fiberglass imvamisa i-substrate yokuzikhethela ngenxa yesilinganiso sayo esiyingqayizivele sokuqina kwesisindo nokuqina kobukhulu. Kodwa-ke, ezinye izinto ezifana ne-ARAMID, i-polyester, noma ngisho ne-carbon fiber ingasetshenziswa ngokuya ngezidingo ezithile zohlelo lokusebenza. Indwangu eyisisekelo idlala indima ebalulekile ekunqumeni izakhiwo ezenziwayo zomkhiqizo wokugcina, kufaka phakathi amandla ashubile, ukumelana nezinyembezi kanye nokuvumelana nezimo.

Amasu okusebenza kwe-PTFE

Inqubo yokusebenzisa i-PTFE endwangu eyisisekelo ingukusebenza okuqondile futhi okuyinkimbinkimbi. Abakhiqizi basebenzisa amasu ahlukahlukene ukufezekisa ubukhulu bokuphakanyiswa kanye nobunye. Indlela eyodwa evamile kubandakanya ukusabalalisa izinhlayiya ze-PTFE ku-liquid medium, bese isetshenziswa kwindwangu ngokufaka i-dip coating noma izinqubo zokufafaza. Ngemuva kwesicelo, indwangu ehlanganisiwe ithola uchungechunge lwemijikelezo yokufudumeza, eyaziwa ngokuthi yi-sontering, lapho amazinga okushisa angadlula khona ama-700 ° F (371 ° C). Le nqubo incibilikisa izinhlayiya ze-PTFE, zibabizele engxenyeni eqhubekayo, engafinyeleleki enamathela ngokuqinile endwangu eyisisekelo.

Ukulawulwa kwekhwalithi nokuhlola ukusebenza

Izindlela zokulawula ezisezingeni eliphakeme zisetshenziswa kuyo yonke inqubo yokukhiqiza ukuze kuqinisekiswe ukuvumelana kanye nokwethenjwa kwendwangu ye-PTFE ehlanganisiwe . Kusetshenziswa imishini yokuhlola ethuthukisiwe ukuhlola amapharamitha wokhiye njengokuqina, amandla okunamathela, kanye nobushelelezi bendawo. Ukuhlolwa kokusebenza kulingisa izimo zangempela zomhlaba, ukuhlola izakhiwo njenge-hydrophobicity, ukumelana kwamakhemikhali, nokuqina ngaphansi kwamazinga okushisa aphezulu. Lezi zinhlaka eziqinile zokuqinisekiswa kwekhwalithi ziqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana noma weqa amazinga ezimboni kanye nokucaciswa kwamakhasimende.

Izakhiwo ezihlukile nezinzuzo ze-PTFE Camera Facrics

Ukuqina okushisayo nokumelana nokushisa

Enye yezimpawu eziphawuleka kakhulu zezindwangu ezihlanganisiwe zePTFE ukuqina kwazo okuhlukile okushisayo. Lezi zinto zokwenziwa zingamelana nokuvezwa okuqhubekayo kumazinga okushisa asuka ku -100 ° F kuya ku-500 ° F (-73 ° C kuya ku-260 ° C) ngaphandle kokonakaliswa. Lokhu kumelana nokushisa okuvamile kwenza izindwangu ze-PTFE zihlanganiswe ngezicelo ezisetshenziselwa izicelo ezisezingeni eliphakeme, njengezithelo zezimboni, imishini yokubopha ukushisa, kanye nezinto ze-aerospace. Amandla okugcina ubuqotho bohlelo nokusebenza ngaphansi kwezimo ezingekho emthethweni abeka izindwangu ezihlanganisiwe ze-PTFE ngaphandle kwezinto ezijwayelekile, anikeze onjiniyela kanye nokuguquguquka okungenakuqhathaniswa kwezixazululo zokuphathwa kwe-thermal.

Ukumelana kwamakhemikhali nokuphikisana nokugqwala

I-PTFE ehlukile ye-Molecular ehlukile ye-PTFE PTFE izindwangu ezihlanganisiwe izindwangu ezingenakuqhathaniswa zokungena kwamakhemikhali. Lezi zinto zokwenziwa zimelana namakhemikhali wonke, kufaka phakathi ama-acid aqinile, izisekelo, nama-solvents, ngaphandle kwezinto ezimbalwa ezingaphandle. Lokhu kumelana kwamakhemikhali okumangalisayo kwenza izindwangu ze-PTFE zihlanganiswe ezindaweni ezilimazayo, njengezitshalo zokucubungula amakhemikhali, ama-laboratories kanye nezindawo zokukhiqiza ezenza imithi. Imvelo ye-inert ye-PTFE ibuye ivimbele ukusabela kwamakhemikhali noma ukungcoliswa, ukuqinisekisa ubumsulwa bezinto ezisetshenzisiwe futhi bandise isikhathi sokuphila kwemishini yamakhemikhali anzima.

Izakhiwo ezingezinhle nokuhlanza okulula

Amandla we-PTFE aphansi we-PTFE anika izakhiwo ezinhle kakhulu ezingezona izinti endwangu ye-teflon ehlanganisiwe . Lesi sici sizuzisa kakhulu kuzinhlelo zokusebenza lapho ukukhishwa kwezinto okubonakalayo nokuhlanza okulula kubalulekile. Ngokucutshungulwa kokudla, ngokwesibonelo, amabhande e-PTFE ahlanganisiwe ahambisa ukuhambisa izinto ezibushelelezi zezinto zokudla ezinamathelayo noma ezintekenteke ngaphandle kwezinkinga zokunamathela. Indawo engeyona induku nayo yenza lula izinqubo zokuhlanza, ukunciphisa isikhathi sezindleko nezindleko. Kuzicelo zezakhiwo, izindwangu ezihlanganisiwe ze-PTFE ezisetshenziswa ezinhlakeni zeTensile zimelana nokuqongelela okungcolile futhi zingahlanzwa kalula ngamanzi, zigcina isikhalazo sabo sobuhle ngenxa yezikhathi ezengeziwe.

Izicelo kanye nezimboni zisebenzisa izindwangu ezihlanganisiwe ze-PTFE

I-Aerospace ne-Aviation

Imboni ye-aerospace ithembele kakhulu kwindwangu ehlanganisiwe ye-PTFE ngokusebenza kwayo okuhlukile ezimweni ezimbi kakhulu. Lezi zinto zokwenziwa zisetshenziswa ezindizeni zezindiza, izinhlelo zikaphethiloli, kanye nezicelo zokufaka. Izindwangu ze-PTFE Camera Call fiberglass zisebenza njengezithiyo ezinhle kakhulu zelangabi, zihlangabezana nemigomo yokuphepha ngomlilo eqinile. Ekuhlolweni kwesikhala, izinto ezihlanganisiwe ze-PTFE zisetshenziswa ezinhlelweni zokuvikela ama-spacecraft, lapho amandla abo okubekezelela ukuguquguquka kwezinga lokushisa ngokweqile futhi amelane nokuwohloka endaweni enokhahlo. Uhlobo olungasindi lwalezi zindwangu luphinde lube nomthelela ekusebenzeni kahle kophethiloli kanye nokulayishwa kwamandla ezicelo ze-aerospace.

Ukucubungula kanye nokukhiqiza izimboni

Ezimweni zezimboni, izindwangu ezihlanganisiwe ze-PTFE zithola ukusetshenziswa okubanzi ekusebenzeni okuhlukahlukene nokukhiqiza imisebenzi. Zivame ukuqashwa ngamabhande okuhambisa ukucubungula ukudla, ukupakisha, kanye nezimboni zezindwangu, lapho izimboni zazo ezingezona izinti nezici zokuhlanza okulula zithuthukisa umkhiqizo kanye nenhlanzeko. Izitshalo ezicubungula amakhemikhali zisebenzisa izindwangu ezihlanganisiwe ze-PTFE kuzinhlelo ze-Filtration, ama-gaskets, kanye nama-linings amathangi namapayipi, asebenzisa ngokunenzuzo ukumelana kwawo kwamakhemikhali nokuqina. Amandla wezezinto zokubekezelela amazinga okushisa aphakeme abenza babe nelungele ukusetshenziswa ezinhlanganweni zokomisa nokwelashwa emikhakhelweni eminingi.

Izicelo zezakhiwo nezokwakha

Imboni yezokwakha iye yamukele izindwangu ezihlanganisiwe ze-PTFE ngenhlanganisela yazo eyingqayizivele yamandla, ukuqina, kanye nesikhalazo sobuhle. Lezi zinto zokwenziwa zisetshenziswa kabanzi ekwakhiweni kwe-tensaile, kudala izakhiwo ezihlaba umxhwele nezisebenzayo ezifana nophahla lwenkundla, ama-canopies, kanye nama-façade. Izindwangu ze-PTFE ezihlanganisiwe zinikeza ukuhanjiswa okuhle kakhulu ngenkathi kuhlinzeka ngokuvikelwa kwe-UV, kubenza balungele ukudala izikhala ezikhululekile, ngokwemvelo. Izakhiwo zabo zokuzihlanza kanye nokumelana nokuwohloka kwemvelo kuqinisekisa ukusebenza okuhlala isikhathi eside kuzicelo zangaphandle. Ngaphezu kwalokho, uhlobo olungamelana nomlilo lwezindwangu ezihlanganisiwe zePTFE lunomthelela ekwakheni ukuphepha, ukuhlangana nezidingo eziqinile zezomlilo zomlilo ezinkombeni eziningi.

Ukugcina

Izindwangu ze-PTFE ezihlanganisiwe zimelela i-pinnacle yezobunjiniyela bezinto zokwakha, enikeza inhlanganisela eyingqayizivele yezakhiwo ezizenza zibaluleke kakhulu emikhakheni ehlukahlukene. Ukusuka ekushiseni kwabo okuhlukile nasekumelaneni kwamakhemikhali ezindaweni zabo ezingezona izinti nokuqina, lezi zinto zokwakha ziyaqhubeka nokucindezela imingcele yalokho okungenzeka ezindaweni ezingejwayelekile. Njengoba kuthuthukiswa ubuchwepheshe kanye nezicelo ezintsha, izindwangu ezihlanganisiwe ze-PTFE zilungele ukudlala iqhaza eliphambili ekuxazululeni izinselelo zobunjiniyela ezinzima nokushayela okusha emasimini ahlukahlukene.
