Intambara hamwe nubudodo bwimyenda ya fiberglass igena imikorere ya PTFE yubushyuhe bwo hejuru. Ubucucike buri hejuru bwongera imbaraga zingirakamaro hamwe nubuso bworoshye ariko bigabanya imbaraga zamarira (inverted U-curve), guhinduka, no kwinjirira. Ubucucike bwiza buringaniza kwinjira, kurwanya amarira, guhinduka, no kurangiza hejuru. Ubucucike buke bukwiranye no kugonda; ubucucike bukabije kubutari inkoni.

Calendering - gukanda umwenda ushyizweho na PTFE hagati yindorerwamo zishyushye zishyushye kuri 360-380 ° C - uhindura kuburyo bugaragara imiterere yimiterere, kurekura ibintu, kudahinduka, hamwe nubukanishi. Igabanya ubukana kuva kuri Ra 0.5-1.0 mkm kugeza kuri <0,05 mm, ifunga pinholes, itezimbere imyambarire, ariko igabanya imbaraga zamarira no guhinduka. Ibyingenzi kurekura imirongo hamwe no gukwirakwiza amashanyarazi.

Imyenda ya PTFE yubushyuhe bwo hejuru hamwe nigitambara cya silicone byombi bikoresha umwenda wa fiberglass nkibanze ariko bitandukanye mubikoresho byo gutwikira (PTFE resin vs silicone rubber). PTFE irusha abandi kutagira inkoni, kwambara, no kurwanya imiti igera kuri 260 ° C. Umwenda wa Silicone utanga ibintu byoroshye guhinduka, kubika amashanyarazi, no kurwanya umuriro (kugeza kuri 230 ° C). Hitamo ukurikije ibyo ushyira imbere.

Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE membrane material) ni ihitamo ryiza kubwubatsi bubi. Ibyiza byingenzi: ubuzima bwimyaka 30+ yo hanze, kwisukura hejuru (amazi yimvura yoza umwanda), kohereza urumuri rworoshye (6-13%), Urwego rwumuriro A, nimbaraga zisa nicyuma munsi ya 1.5 kg / m². Ikoreshwa muri stade, ibibuga byindege, ninyubako zishushanyije kwisi yose.

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 zayo, imbogamizi (ibyuma bya alkali byashongeshejwe, imiti ikomeye ya fluorine), nibintu byingenzi nkubushyuhe, kwibanda, hamwe no guhangayika.

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

Iyi ngingo isobanura impamvu umwenda wa fiberglass udafite alkali ari substrate yemewe kumyenda yubushyuhe bwo hejuru bwa PTFE. Ikubiyemo imiti ihuza imiti ikoresheje ibikoresho bya silane hamwe nibintu byingenzi bifatika nkubushyuhe bwumuriro, guhagarara neza, hamwe no kurwanya ruswa - kwemeza imikorere irambye mubidukikije.
