Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE isize fiberglass) ifite imbaraga zo kurwanya flex kuko substrate ya fiberglass isanzwe ivunika. Imyenda yoroheje (0.08mm) irokoka amagana kugeza ku bihumbi; amanota aremereye (> 0,25mm) gucamo nyuma ya mirongo. Ububoshyi bwa Satin burenze kuboha. Kugirango uhore usubiranamo, tekereza firime ikomeye ya PTFE cyangwa imyenda ishingiye kuri aramid aho.

Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE isize fiberglass) ikoreshwa cyane mugucapura imyenda no gusiga irangi kumukandara wohereza ubushyuhe (180-230 ° C), kumeza yerekana imashini yerekana imashini, kumisha imikandara ya mesh, guhuza imikandara yimashini, no gufunga imashini. Ubuso bwacyo butari inkoni birinda inkuta / ibisigisigi, kugabanya isuku kumasaha no kuzamura ubwiza bwimyenda. Imikandara itagira iherezo ituma umusaruro uhoraho.

Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE ikozweho fiberglass) nigitangazamakuru cyambere cyo kuyungurura ibintu mubihe bikabije: kuvanaho umukungugu wa gazi (sima, gutwika imyanda, guteka amakara kugeza kuri 260 ° C), kuyungurura amazi yangiza (acide, alkalis, amavuta), kuyungurura ibiryo / imiti ya sterile, hamwe na filtri ya HEPA. Ubuso butari inkoni burinda umukungugu kandi butuma isuku yoroshye. Indangamanota ya Membrane igera kumurongo urenze urugero.

Imyenda ya PTFE yubushyuhe bwo hejuru ikomeza amashanyarazi meza kuva kuri -180 ° C kugeza kuri 260 ° C: kurwanya ubukana> 10¹³ Ω · cm kuri 200 ° C, guhora dielectric ihagaze neza kuri 2.0-2.1. Hejuru ya 260 ° C, PTFE yoroshye, ibora hejuru ya 327 ° C, itakaza ubwishingizi burundu. Munsi ya 0 ° C, insulasiyo iratera imbere ariko gutwikira biba byoroshye. Guma muri 260 ° C kugirango ukore neza.

Imyenda yubushyuhe bwo hejuru ya PTFE (fiberglass ya PTFE) ni nziza kumukandara utanga ibiryo kubera ubushyuhe bwayo 260 ° C, -70 ° C ubukonje bukabije, ubuso butari inkoni, hamwe na FDA. Ibyingenzi byingenzi: amashyiga yimigati (ibisuguti, umutsima, pizza), ibyokurya bikaranze, imirongo ikonjesha bombo, tunel ikonjesha, ibyuma bifata ubushyuhe, hamwe no kuzinga. Kugabanya imyanda nigihe cyo gukora isuku.

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 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.
