Izakhiwo Ezihlukile ze-PTFE Film Tape yezicelo zikagesi
I-Superior Electrical Insulation
Itheyiphu yefilimu ye-PTFE inamandla akhethekile e-dielectric, iyenza iphumelele kakhulu ekunikezeni ukwahlukanisa okuthembekile kukagesi. Lesi sakhiwo esiyingqayizivele sisiza ukuvimbela ukuvuza kwamanje, i-arcing, kanye nokuwohloka kukagesi, ngisho nasezindaweni ezine-voltage ephezulu. Ukungaguquguquki kwayo okuphansi kwe-dielectric kuthuthukisa ukusebenza ngokunciphisa ukulahleka kwesignali kanye nokunciphisa ukuphazamiseka kwe-electromagnetic, okubalulekile ezinhlelweni zikagesi ezibucayi. Njengomphumela, itheyiphu yefilimu ye-PTFE ivamise ukusetshenziswa ezinhlelweni ezifana nokufakwa kwamakhoyili, ukugoqa ikhebula, ukuvikelwa kwebhodi lesifunda, nokunye ukufakwa kukagesi okufunayo.
Ukumelana Nokushisa
Esinye sezici ezihlaba umxhwele kakhulu zetheyiphu yefilimu ye-PTFE yikhono layo lokumelana nezinga lokushisa elidlulele, kusukela ku -70°C kuya ku-260°C (-94°F kuya ku-500°F). Lokhu kubekezelelana okuphezulu kokushisa kuqinisekisa ukuthi i-tape ihlala izinzile, iguquguquka, futhi isebenza kuzo zombili izimo ze-cryogenic nezishisa kakhulu. Ilungele izindawo lapho ukuhamba kwamabhayisikili ashisayo kwenzeka khona noma lapho izingxenye zichayeka ekushiseni okukhulu, njengasemoyeni, ezimotweni, noma kumasistimu okucubungula izimboni. Abakhiqizi be-teflon tape bayaqaphela ukuthi ukusebenza kwayo kuhlala kungashintshi, okuyenza ibe ukukhetha okunokwethenjelwa kwezinhlelo zokusebenza ezibucayi lokushisa.
Ukungangeni Kwamakhemikhali
Itheyiphu yefilimu ye-PTFE imelana ngokwemvelo nezinhlobonhlobo zamakhemikhali, izincibilikisi, nezinto ezonakalisayo, ngenxa yesakhiwo sayo esiyingqayizivele samangqamuzana. Lokhu kungenzi lutho kwamakhemikhali kuyenza ikwazi ukugcina ubuqotho bayo ngisho nalapho ibhekene nezinto ezinolaka, okuhlanganisa ama-asidi, izisekelo, uwoyela, namafutha. Itheyiphu ayilulazi, ikhukhumale, noma ilahlekelwe ukunamathela ngaphansi kwezimo zemvelo ezinzima, okuyenza ibe yisixazululo esihle kakhulu sezimboni, ukucubungula amakhemikhali, kanye nezicelo zasolwandle. Ukuqina kwayo kuqinisekisa ukwethembeka kwesikhathi eside futhi kunciphisa isidingo sokushintshwa njalo ezilungiselelweni eziyinselele yamakhemikhali.
