Itheyiphu yokunamathisela ye-PTFE , eyaziwa nangokuthi i-Teflon adhesive tape, igqama ngezinto zayo ezingabambisi futhi zimelana namakhemikhali. Lezi zici eziyingqayizivele zisuka esakhiweni samangqamuzana e-polytetrafluoroethylene (PTFE), ehlanganisa amabhondi e-carbon-fluorine aqinile. Lokhu kumiswa kudala amandla aphansi angaphezulu, okuvimbela izinto ekubambeleleni kuwo. Ukwengeza, ukungabi namakhemikhali kwamakhemikhali we-PTFE kuyenza imelane nezinhlobonhlobo zamakhemikhali, ama-acids, nezincibilikisi. Inhlanganisela yalezi zakhiwo yenza itheyiphu yokunamathisela ye-PTFE Teflon ibe yinto eyigugu ezimbonini ezihlukahlukene, kusukela ekucutshungulweni kokudla kuye ekukhiqizeni amakhemikhali, lapho izindawo ezinganamathiki nokumelana namakhemikhali kubalulekile ekugcineni ukusebenza kahle nokuphepha.

Isayensi Engemuva Kwezakhiwo Ezingagxili ze-PTFE
Isakhiwo samangqamuzana e-PTFE
Isakhiwo samangqamuzana esiyingqayizivele se-PTFE iyisisekelo sezakhiwo zayo ezinganamathi. I-polymer iqukethe i-carbon backbone ene-athomu ye-fluorine enamathiselwe kukhabhoni ngayinye. Leli lungiselelo lakha i-molecule ezinzile futhi elinganayo. Amabhondi e-carbon-fluorine aqinile abangela into enamandla angaphezulu aphansi kakhulu, okusho ukuthi ezinye izinto zinobunzima bokunamathela endaweni yayo.
Amandla Asezindaweni Eziphansi Nemiphumela Yawo
Amandla aphansi angaphezulu wetheyiphu yokunamathela ye-PTFE abalulekile ekuziphatheni kwawo okunganamatheli. Lesi sakhiwo sisho ukuthi ingaphezulu letheyiphu likhanga kancane kwezinye izinto. Uma izinto zihlangana ne-PTFE, zihlangabezana nendawo enikeza ukuxhumana okuncane noma okungekho kwamangqamuzana. Ngenxa yalokho, uketshezi luyakhuphuka futhi okuqinile kusheleleke kalula, okwenza itheyiphu yokunamathela ye-PTFE Teflon ilungele izinhlelo zokusebenza lapho ukuvimbela ukunamathela kubalulekile.
Ukuqhathanisa Nezinye Izinto
Uma kuqhathaniswa nezinye izinto, izakhiwo ze-PTFE ezinganamatheli zihlukile ngempela. Ngokungafani nezinsimbi, amapulasitiki, noma amanye ama-fluoropolymers, i-PTFE ibonisa ikhono elingenakuqhathaniswa lokuxosha izinto. Lokhu kwenza itheyiphu yokunamathela ye-PTFE ibe phezulu ezinhlelweni lapho ezinye izinto zingase zehluleke ngenxa yokunamathela noma izinkinga zokunamathela. Ukusebenza kwetheyiphu ezinhlelweni ezinganamatheli kuvame ukudlula ezinye izindlela, okuyenza ibe ukukhetha okuthandwayo ezimbonini ezisukela ekulungiseni ukudla kuye emkhathini.
Ukumelana Kwamakhemikhali kwe-PTFE Adhesive Tape
Ukungabi Nalutho Kwekhemikhali Kuchaziwe
Ukumelana kwamakhemikhali kwe-PTFE Teflon adhesive tape kusekelwe ekungangeni kwayo kwamakhemikhali. Lesi sakhiwo sisuka kumabhondi e-carbon-fluorine aqinile ku-molecule ye-PTFE. Lezi zibopho zizinzile kangangokuthi zimelana nokuphuka noma ukusabela ngamakhemikhali amaningi. Ngenxa yalokho, i-PTFE ihlala ingathinteki uhla olubanzi lwezinto, okuhlanganisa ama-asidi aqinile, izisekelo, nezinyibilikisi eziphilayo. Lokhu kuzinza kwamakhemikhali kwenza itheyiphu yokunamathela ye-PTFE ibe yisinqumo esifanelekile sohlelo lokusebenza ezindaweni zamakhemikhali ezinokhahlo.
Ibanga Lokumelana Namakhemikhali
Itheyiphu yokunamathisela ye-PTFE ibonisa ukumelana okuphawulekayo nohlu olubanzi lwamakhemikhali. Ihlala ingathinteki i-hydrochloric acid, i-sulfuric acid, nezinyibilikisi ezihlukahlukene ze-organic ezinganciphisa ezinye izinto eziningi. I-tape iphinde imelane ne-oxidation kanye nesimo sezulu, igcina izakhiwo zayo ngisho nasezimweni zangaphandle eziyinselele. Lo mkhakha obanzi wokumelana namakhemikhali uvumela itheyiphu yokunamathela ye-PTFE Teflon ukuthi isetshenziswe ezinhlelweni ezihlukene, kusukela kumishini yaselabhorethri kuya ezimbonini zokucubungula amakhemikhali.
Imikhawulo Nokucatshangelwa
Nakuba ukumelana kwamakhemikhali kwe-PTFE kuhlaba umxhwele, kubalulekile ukuqaphela ukuthi akunamandla okumelana nazo zonke izinto. Izinhlanganisela ezithile ezisebenza kakhulu, njenge-elemental fluorine noma izinsimbi ze-alkali ezincibilikisiwe, zingathinta i-PTFE. Ukwengeza, emazingeni okushisa aphezulu kakhulu, amanye amakhemikhali angase aqale ukusebenzisana ne-PTFE. Ukuqonda le mikhawulo kubalulekile ekukhetheni ibanga elilungile letheyiphu yokunamathela ye-PTFE yezinhlelo zokusebenza ezithile. Ukucatshangelwa okufanele kwezimo zokusebenza kuqinisekisa ukusebenza kahle nokuphila isikhathi eside kwe-tape ezindaweni ezihlukahlukene zamakhemikhali.
Izicelo Ezisebenzisa Ukumelana Non-Stick kanye Nekhemikhali
Ukusetshenziswa Kwezimboni
Ezilungiselelweni zezimboni, izakhiwo ze-PTFE ezinamathelayo ezinganamatheli futhi zimelana namakhemikhali zithola izinhlelo zokusebenza eziningi. Itheyiphu ivame ukusetshenziswa njengolwelwesi oluvikelayo emathangini okugcina amakhemikhali namapayipi, ukuvimbela ukugqwala nokuhlasela kwamakhemikhali. Embonini yendwangu, i-PTFE Teflon adhesive tape isetshenziswa emishinini yokuvala ukushisa ukuze kuvinjelwe indwangu ukuthi inganamatheli ngesikhathi senqubo yokuvala. Imboni ye-aerospace isebenzisa itheyiphu ukuhlanganisa izintambo zezintambo futhi njengesendlalelo esivikelayo ezinhlelweni zikaphethiloli, isizakala ngokumelana kwayo namakhemikhali kanye nezakhiwo zokungqubuzana okuphansi.
Ukucubungula Ukudla kanye Nokupakishwa
Imboni yokudla izuza kakhulu kuzici ze -PTFE ezinamathelayo ezinganamatheli. Ivamise ukusetshenziswa emishinini yokupakisha ukudla, lapho indawo yayo enganamathele ivimba izinto ezinamathelayo nezinhlayiya zokudla ukuthi zinganqwabelana, kuqinisekiswe ukusebenza kahle nokugcina izindinganiso zokuhlanzeka. Emabhikawozi, amabhande okuthutha anama-PTFE namashidi okubhaka avimbela inhlama nezimpahla ezibhakiwe ukuthi zinganamatheli, athuthukise ikhwalithi yomkhiqizo futhi anciphise imfucuza. I-inertness yamakhemikhali ye-PTFE iphinde iqinisekise ukuthi azikho izinto ezingafuneki ezingena emikhiqizweni yokudla, okwenza kuphephe ekusetshenzisweni kokudla okuqondile.
Izicelo Zaselabhorethri Nezokwelapha
Ezilungiselelweni zaselabhorethri, ukumelana namakhemikhali we-PTFE Teflon adhesive tape kubaluleke kakhulu. Isetshenziselwa ukuvala amalunga ezitsheni zengilazi nezinto zokusebenza ezichayeke kumakhemikhali abolayo, okuqinisekisa ubuqotho bokuhlolwa. I-tape iphinde ithole ukusetshenziswa kumishini ye-chromatography, lapho izakhiwo zayo ezingezona izinduku zivimbela ukungcoliswa kwesampula. Ezinhlelweni zezokwelapha, iteyiphu yokunamathisela ye-PTFE isetshenziswa ekwenzeni amadivaysi athile afakelwayo ngenxa yokuhambisana kwayo kwezinto eziphilayo kanye nokumelana noketshezi lomzimba. Izakhiwo zayo ezingezona izinduku ziyenza ibe wusizo emikhiqizweni yokunakekela amanxeba, okuvumela izinguquko zokugqokisa ezilula, ezingenabuhlungu.
Isiphetho
Izakhiwo ze -PTFE ezinamathelayo ezingavamile ezinganamatheli futhi zimelana namakhemikhali ziyenza ibe yinto ebaluleke kakhulu kuzo zonke izimboni. Isakhiwo sayo samangqamuzana esiyingqayizivele sinikeza amandla angaphezulu aphansi axosha izinto, kuyilapho ukungabi namakhemikhali kwawo kunikeza isivikelo ezinhlobonhlobo zezinto ezigqwalayo. Kusukela kuzicelo zezimboni kuya ekucutshungulweni kokudla kanye nasekusetshenzisweni kwezokwelapha, i-PTFE Teflon adhesive tape iyaqhubeka nokufakazela ukubaluleka kwayo ezimeni lapho izinto zendabuko kusilela khona. Njengoba izimboni zithuthuka futhi zibhekana nezinselele ezintsha, ukuguquguquka nokuthembeka kwetheyiphu yokunamathela ye-PTFE kuqinisekisa ukuhambisana nokubaluleka kwayo okuqhubekayo ekukhiqizeni kwesimanje kanye nentuthuko yezobuchwepheshe.
