Ubushyuhe bwikirahure (Tg) bwa silicone yumuvuduko ukabije ni -120 ° C - munsi cyane ugereranije na acrylic. Iyi ultra-low Tg ituma PTFE yubushyuhe bwo hejuru ya kaseti ihindagurika kandi ikomera ndetse no kuri -70 ° C, ikarinda gucika intege kandi igafasha kwizerwa mubikorwa bya cryogenic.

PTFE yubushyuhe bwo hejuru irashobora guturika cyangwa kuvunika mugihe cyunamye no gufungura. Iyi ngingo isobanura uburyo bwo kwirinda ibi binyuze mu guhitamo neza substrate (fibre fibre yongerewe imbaraga), uburebure bwiza (0.18mm nkibisanzwe), guhitamo silicone, hamwe nubuhanga bwo kwishyiriraho.

Imyenda ya PTFE itanga ubushyuhe budasanzwe itanga imiti idasanzwe, irwanya aside ikomeye, alkalis, ibishishwa kama, hamwe na gaze yangirika. Iyi ngingo irambuye ibintu birwanya imbaraga, aho bigarukira (ibyuma bya alkali byashongeshejwe, ibintu bikomeye bya fluorine), nibintu byingenzi nkubushyuhe, kwibanda, hamwe nuburemere bwimashini.

Guhitamo impapuro zo gusohora cyangwa firime substrate no kurekura bigira ingaruka itaziguye kububiko no gukuramo imikorere ya PTFE yubushyuhe bwo hejuru. Iyi ngingo igereranya PET na kraft impapuro substrates hamwe na silicone na fluorine yo kurekura, irasaba guhuza uburyo bwiza bwo gukuramo zeru-ibisigara no kwizerwa igihe kirekire.

Kaseti ya PTFE yubushyuhe bwo hejuru ikoreshwa cyane mugukwirakwiza amashanyarazi, ariko ibihe byinshi hamwe na voltage nyinshi bitera ingaruka zidasanzwe: gusenyuka kwamashanyarazi, gusohora igice, gusaza k'umuriro, gutakaza ibimenyetso byumuvuduko mwinshi, no kumva ibidukikije. Iyi ngingo isobanura buri kaga nuburyo bwo kubyirinda.

Kwinjiza PTFE ntabwo bigarukira gusa kumyenda ya fiberglass. Iyi ngingo itangiza ubundi buryo 7 - aramid, fibre karubone, PBI, ibyuma byoroshye, grafite, asibesitosi (ikuweho), hamwe na ceramic yuzuza - hamwe nibikorwa byabo, ibyiza, imipaka, hamwe nibikorwa byingenzi.

Imyenda ihumeka cyane PTFE yubushyuhe bwo hejuru ikomatanya ibintu bidafite inkoni, ituze ryumuriro, hamwe nikirere. Iyi ngingo irasobanura ibyingenzi byingenzi mukumisha imyenda, gutunganya ibiryo, gukora inganda, ibikoresho bya elegitoroniki, gutanga pneumatike, kurengera ibidukikije, nibikoresho byubaka.

Iyi ngingo isobanura uburyo bwo kwirinda kwanduza no kwangiza imikorere kuruhande rudafatanye na kaseti ya PTFE yubushyuhe bwo hejuru mugihe cyo gutwikira. Ingamba zingenzi zirimo kugenzura inkomoko (kuvura neza neza), kwigunga kumubiri (firime ikingira, imashini idafatika, gukama zone), hamwe no gucunga neza inzira.

Iyi ngingo isobanura impamvu imyenda ya alkali idafite fiberglass nigitereko gikundwa kumyenda yubushyuhe bwo hejuru bwa PTFE. Irimo guhuza imiti ikoresheje ibikoresho bya silane hamwe nibintu byingenzi bifatika nkubushyuhe bwumuriro, guhagarara neza, hamwe no kurwanya ruswa - kwemeza imikorere irambye mubidukikije.

Gukoresha PTFE yubushyuhe bwo hejuru hejuru yumurongo ugoramye kandi udasanzwe udafite ibibyimba byinshi kandi bigenda neza, inzira isanzwe irakenewe, harimo kwitonda neza, ubuhanga bwo gukoresha umwuga hamwe ningamba zifatika zifasha. Muri byo, substrate kwitegura nintambwe ikomeye cyane, igena hafi 70% yingaruka zanyuma.
