I-Polytetrafluoroethene,isifinyezo:I-PTFE
Isibizo: PTFE, tetrafluoroethylene, plastic king, F4.
Izinzuzo ze-PTFE
I-PTFEiyipulasitiki ekhethekile yobunjiniyela, okwamanje iyizinto ezimelana nokugqwala, ezaziwa ngokuthi "inkosi yepulasitiki".Izici eziyinhloko ukumelana nokushisa okuphezulu nokuphansi, ukumelana nokugqwala, ukufakwa okuphezulu, ukumelana nokuguga, ukuzigcoba.
Isetshenziswa ku-aerospace, electronics kanye nezinto zikagesi, imboni yamakhemikhali, imishini namathuluzi, ukudla nezokwelapha, amaphampu, amavalvu namapayipi, izimoto nemikhumbi, ama-compressor komoya, njll., futhi isiphenduke into ebaluleke kakhulu ekuxazululeni ubuchwepheshe obuningi besimanje imboni.
I-PTFE molecule inert F ama-athomu ivikela futhi ivikele ibhondi ye-CC, futhi i-CF bonding energy izinzile ngokukhethekile, iketango lamangqamuzana kunzima ukubhujiswa, isakhiwo esizinzile kakhulu.Lesi sakhiwo samangqamuzana sichaza izici ezilandelayo ezinhle kakhulu ze-PTFE.
Ukumelana nokugqwala:Ngaphezu kwezinsimbi ze-alkali ezincibilikisiwe nezincibilikisi ezimbalwa ezifana ne-alkane hydrocarbons engaphezu kuka-300 degrees Celsius, imelana nokugqwala kwesikhathi eside yinoma imaphi amanye amakhemikhali.
Ukumelana namazinga okushisa aphezulu naphansi: ingasetshenziswa isikhathi eside ku -60+260℃.
Ukugcoba okuphezulu:i-coefficient encane kakhulu yokungqubuzana phakathi kwezinto eziqinile, ngisho neqhwa alikwazi ukuqhathaniswa nalo.
Ukunganamatheli:ukungezwani okuncane kwendawo phakathi kwezinto eziqinile, akunamatheli kunoma iyiphi into.
Ukumelana Nesimo Sezulu:Impilo ende yokuguga phakathi kwamapulasitiki.
Ukungewona ubuthi:impahla ingasetshenziswa njengemithambo yegazi yokwenziwa, engeyona enobuthi futhi engeyona i-allergic kanye nokunye ukusabela okungekuhle, ngokudla nezinto zebanga lemithi.
Izakhiwo ze-insulating:ifilimu ewugqinsi njengephephandaba yanele ukumelana nogesi wamandla aphezulu angu-1500V.
Ngaphezu kwalokho, i-PTFE futhi ayinakho ukumuncwa komswakama, ukungashi, futhi idlula umoya-mpilo, ukukhanya kwe-ultraviolet.
Ukungalungi kwe-PTFE
Nakuba i-PTFE inokusebenza okuhle kakhulu okuphelele, kodwa amandla emishini aphansi, i-coefficient enkulu yokunwetshwa komugqa, ukumelana nokugqokwa okumpofu, ukumelana nokukhuphuka okuphansi, ukungahambi kahle kokushisa nokunye ukushiyeka.Kumandla emishini nezinye izimo eziyinkimbinkimbi, ezinjengokusetshenziswa embonini yokuvala ama-valve kanye nomkhawulo wangempela wokusetshenziswa okuphephile kwezinga lokushisa ngokuvamile lingaphakathi -70 ~ +150℃.Ukuze unqobe lezi phutha, i-PTFE resin ingagcwaliswa ngama-ejenti aqinisayo ukuze kuthuthukiswe izakhiwo zemishini yezinto ezibonakalayo, ukuze kwandiswe ububanzi bokusetshenziswa kwezinto zayo.
Isingeniso sezakhiwo ze-PTFE ezinemibala
Umbala wangempela we-PTFE umhlophe qhwa, kuyilapho i-PTFE enombala ingenxa yokuthi impahla eyisisekelo ye-PTFE igcwele izinto ezisizayo.Izinto ezisizayo zingahlukaniswa zibe izigaba ezimbili ngokuya ngokusetshenziswa: i-ejenti yokuthuthukisa kanye ne-ejenti ye-powder yombala.
Ikilasi le-ejenti ye-powder yombala: ligcwele impushana yombala ku-PTFE, lingaba ngokukhululekile libe mnyama, ophuzi, obomvu, oluhlaza okotshani, oluhlaza okwesibhakabhaka njalo njalo.I-ejenti ye-powder yombala iwukushintsha kuphela umbala we-PTFE, isilinganiso sesigcwalisi siyinani elincane ngakho umphumela wokusebenza kwasekuqaleni kwe-PTFE ungashaywa indiva.Ngokwethiyori, i-ejenti ye-powder yombala kufanele ikwazi ukuthikameza ukuzinza kwamakhemikhali kwe-PTFE, ukwahlukanisa, amandla okudonsa kanye nezinye izici zemishini.Ngakho-ke, ezinye izikhathi ezikhethekile kudingeka wazi ngakho.I-PTFE enombala ihlangabezana nezidingo zamakhasimende anezidingo zemibala ebonakalayo.
Ukuthenga ishubhu ye-PTFE efanele akukhona nje kuphela ngokukhetha imininingwane ehlukene yezinhlelo zokusebenza ezahlukene.Okuningi ukukhetha umenzi onokwethenjelwa.BesteflonI-Fluorine plastic Industry Co., Ltd. igxile ekukhiqizeni izinga eliphezuluAmapayipi we-PTFEnamashubhu iminyaka engu-20.Uma noma yimiphi imibuzo nezidingo ze-ptfe tube, sicela ukhululeke ukuxhumana nathi ukuze uthole iseluleko esithe xaxa sochwepheshe.
