I-PTFE film tape ibonwa kabanzi ngendawo yayo ehlukile engeyona induku, ukumelana okushisa okuphezulu, nokuqina kwamakhemikhali, okwenza kube yisixazululo esithandwayo ezinhlelweni ezahlukahlukene zezimboni. Le tampu yenziwa ngefilimu ye-polytetrafluoroethylene (PTFE), ivame ukuhlanganiswa nokunamathela kwe-silicone ohlangothini olulodwa, ukuvumela ukunamathela ngokuphepha ukuze kuthathwe ngokuphepha lapho kugcina izakhiwo zayo zokusebenza okuphezulu. Ukusetshenziswa kwalo kufinyelela kuzo zonke izimboni ezifuna ukuthembeka ezimweni ezimbi kakhulu - ukubekwa uphawu kokushisa, ukufakwa kukagesi, kanye nokusebenza kwamakhemikhali ukuba phakathi kokuvamile.
Ngamandla ayo okwenza ngaphansi kwemibandela efunwayo, i-PTFE film tape isibe yinto eyisisekelo kuzo zombili izimo zezobuchwepheshe ezijwayelekile nezikhethekile.

Ngabe i-PTFE film tape ithuthukisa kanjani izinqubo zokushisa zokushisa?
Ensimini yokushisa yokushisa, i-PTFE film tape idlala indima ebalulekile ekuqinisekiseni ukusebenza okuhlanzekile, okusebenzayo, kanye nokungaguquki - ikakhulukazi izimboni zokupakisha zezokwelapha. Indawo yayo engeyona induku, eyakhiwe yi-PTFE Coating, yenzelwe ngokukhethekile ukwenza njengesithiyo phakathi kwezinto ezivuthayo nezinto zokwakha. Lokhu kuvimbela amafilimu epulasitiki ekuncibilikiseni imigoqo yokufudumeza, eqeda isikhathi sokuphumula esibangelwa ukwakheka kokunamathela noma okusele ezintweni ezibonakalayo.
Ukumelana Nezinga lokushisa kwezimpawu ezizinzile
Ukubekezelela okuphezulu kwe-Ptfe, ukufinyelela kuze kufike ku-260 ° C (500 ° F), kwenza kubekelwe ngokukhethekile ngezindawo ezifunwayo njengemishini yokubopha esheshayo. Lokhu kumelana nokushisa kuvumela itheyiphu ukwenza ngokuthembekile ngaphansi kokuvezwa isikhathi eside kumazinga okushisa aphakeme, ukunciphisa amathuba okuthambisa, ukugoqa, noma ukuqhekeka okunamathela. Ukuqina kwayo kusiza ukugcina imijikelezo yokuvala kahle uphawu, ukunciphisa ukuphazamiseka kanye nokwenza ngcono ukukhiqizwa kokukhiqiza okuphelele.
Umshini othuthukisiwe isikhathi eside nokukhiqiza
Ngokunciphisa ukungqubuzana nokugqokwa ezingxenyeni zokubopha uphawu, itheyiphu yefilimu ye-PTFE inweba impilo yenkonzo yendawo evuthayo. Ama-opharetha nawo ayazuza eziteshini ezimbalwa zokukhiqiza ukuze ahlanze noma afake esikhundleni ama-heater avaliwe. Imishini isebenza ngokushelela ngokushelela, futhi nezikhathi zokulungiswa zidelwa, ezinomthelela ekukhiqizweni jikelele.
Ukuguquguquka kwesicelo
Ukusetshenziswa kwayo akugcini kumathuluzi e-vertical and ave ovundlile. Amateyipu asuselwa e-PTFE nawo alungele imishini yokuvalwa kokubopha, ama-rotary heaters, nezinhlelo zokupakisha ze-blister. Kuzo zonke zalezi zinhlelo zokusebenza, zinikeza indawo yokukhishwa ebushelelezi evumela izinto ezivaliwe zisuswe ngokuhlanzeka nangendlela efanele.
Ngamafuphi, i-PTFE film tape isiza abakhiqizi ukuthi balondoloze ikhwalithi yokupakisha yomkhiqizo engaguquki, banciphise isikhathi sokusebenza, futhi banwebe impilo yezingxenye zokushisa ukushisa okubizayo.
I-PTFE film tape in electrical insertation application
Itheyiphu yefilimu ye-PTFE isungulwe kahle ngokulinganayo ekukhiqizweni kukagesi nakwe-elekthronikhi, lapho ubuqotho bokufakelwa kanye nokuqina okushisayo kubalulekile. Ngenxa yamandla ayo aphezulu we-dielectric kanye nokumelana nezici zezemvelo, le tepi isetshenziswa kaningi ekusongwe kwentambo, ukuguqulwa kwe-transform, kanye nokuvikelwa kwesifunda.
Ukuqina kukagesi ezimeni ezinzima
Le teyipu igcina izakhiwo ezinhle kakhulu ze-dielectric wonke ngaphezulu kwesibalo esibanzi samazinga okushisa kanye namazinga omswakama. Ukuthi kuvezwa ama-voltages aphezulu, ukukhanya kwe-ultraviolet, noma umswakama, ukunamathela kwe-PTFE kunikeza ungqimba oluthembekile lokufakelwa okuvimbela ukuqeda nokuvuza kukagesi. Kuwusizo ikakhulukazi ezindaweni lapho izinto ezijwayelekile zokufakelwa zingahle zinciphise noma zehluleke.
Ukumelana nokuwohloka kwamakhemikhali nokushisayo
I-PTFE yokungena kwamakhemikhali yenza ukuthi itheyiphu imelane nama-acid, izisekelo, kanye nezinsolo ezivame ukwethula ezinhlelweni zikagesi ezisebenza kakhulu. Kuhlanganiswe nokumelana kwayo kokushisa, lokhu kunciphisa ubungozi bokuhluleka kwezithako ngenxa yokuvezwa kwezikhathi ezengeziwe. Lokhu kuqina kubaluleke kakhulu e-aerospace, ezithunzini zokufakwa kukagesi kwezimboni.
I-Anti-Frict kanye nokutholwa komswakama okuphansi
I-coefflent ephansi ye-tape ephansi isiza ukunciphisa ukugqokwa kwezinto ezishukumisayo ezishukumisayo, njengamakhoyili nangama-actuators. Ngokwengeziwe, ukumunca umswakama okuphansi kuvimbela ukuwohloka kwe-dielectric ngesikhathi kungazelelwe izinguquko zokushisa noma ezimweni sezulu ezinomswakama. Lezi zici zifaka isandla ekuthembekeni kwesikhathi eside kokufakwa kwangaphakathi nangaphandle.
Ngokunikela nge-detable, amelana namakhemikhali, kanye nesixazululo esizinzile kagesi, i-PTFE Film Tape inikeza onjiniyela abanenketho ethembekile yokuvikela izakhi zikagesi ezibucayi.
Ingabe i-PTFE film tape ilungele izindawo ezicubungula amakhemikhali?
Izindawo zokucubungula amakhemikhali ziphakathi kwezilungiselelo ezifunwa kakhulu zezimboni, ezibonakala ngamazinga okushisa aphezulu, izinto ezilimazayo, kanye nengcindezi engaguquki. Itheyiphu yefilimu ye-PTFE ilungele kahle le mibandela ngenxa yenhlanganisela yayo eyingqayizivele yokuhlanekezelwa kwamakhemikhali, indawo enganamatheli, nokukhuthazela okushisayo.
Ukumelana kakhulu kwamakhemikhali
Enye yezindawo ezibaluleke kakhulu zetheyiphu yefilimu ye-PTFE yikhono layo ukumelana cishe nawo wonke ama-ejenti amakhemikhali, kufaka phakathi ama-acidi anolaka kanye nama-alkali aqinile. Lokhu kwenza kube yi-lining encamelayo noma ukumboza izikhala ezivezwe ama-splashes amakhemikhali noma ama-growrosive vapors. Ngokungafani nezinye izinto eziningi, i-PTFE ayizenzi noma iphendule ngisho nangemva kokuvezwa isikhathi eside.
Izicelo ekusongeleni ngepayipi nokubopha uphawu lwe-valve
Ezitshalweni zamakhemikhali, itheyiphu yefilimu ye-PTFE ivame ukusetshenziselwa ukusonga amapayipi, ama-valve, nama-flanges ukuhlinzeka ngesendlalelo esengeziwe sokuvikelwa ekuvuthweni nasekugqwalweni. Ukuxhaswa kwayo okunamathela kuvumela uhlelo lokusebenza olulula, kanti indawo engeyona induku iqinisekisa ukuthi ukwakha izinsalela zamakhemikhali kuncishisiwe. Lesi sici senza lula ukuhlanza nokulungiswa, okubalulekile ezindaweni lapho ukungcoliswa kufanele kugwenywe.
Ukusebenza okuphezulu ngaphansi kwengcindezi eshisayo
Ukusabela kwamakhemikhali kuvame ukukhiqiza ukushisa, kanye nemishini ezindaweni ezinjalo kumele ibekezelele ukuhamba ngebhayisikile. Itheyiphu yefilimu ye-PTFE ingakhuthazelela lezi zimo ngaphandle kokuyekethisa ubuqotho bayo bomzimba. Kuyaphikisa ukuqhekeka, ukubhebhana, noma ukugqashula ngisho nangemva kokuchayeka okuguqukayo kumazinga okushisa aguqukayo.
I-PTFE film film tape amandla okwenza ngaphansi kwengcindezi yamakhemikhali ne-thermaal yenza kube yisixazululo esithembekile ezindaweni lapho ukuphepha nokuthembeka ngokwenyama kubalulekile.
Ukubeka kafushane
I-PTFE film tape ifakazela ukuthi impahla ebaluleke kakhulu ezindaweni ezahlukahlukene zobuchwepheshe. Ukuthi uthuthukisa ukusebenza kwemishini yokubopha ukushisa, ukuvikela izinkambiso zikagesi ezibucayi, noma zibeke izimo ezinzima zezitshalo zamakhemikhali, okungezona induku, imvelo eqinile, futhi imvelo emelana namakhemikhali ikuvumela ukuba ihlangabezane nezidingo ezifunwa kwezimboni. Impilo yayo ende yenkonzo kanye nokufakwa kalula kuthuthukisa umsebenzi wayo kuyo yonke imikhakha. Ngeminye imininingwane noma ukucela isampula, zizwe ukhululekile ukuxhumana nathi mandy@akptfe.com.
