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 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.

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.
