Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE isize fiberglass) imara igihe kirekire iyo ibitswe munsi ya 260 ° C, kure yimigezi ikarishye, kandi igasukurwa nibikoresho byoroshye. Ibintu nyamukuru bigabanya ubuzima: kwangirika kwubushyuhe hejuru ya 260 ° C, guhungabana kwubushyuhe buturutse kubushyuhe bwihuse / gukonjesha, umunaniro wubukanishi uva kunama no guhagarika umutima, igitero cyimiti ituruka kumyuma ya alkali yashongeshejwe cyangwa okiside ikomeye, kwangirika kwabashitsi mubyuma mugihe cyo gukora isuku, hamwe na UV ikoreshwa hanze. Ubwiza bwo gutwikira hamwe na substrate nabyo bifite akamaro.

Imyenda yubushyuhe bwa PTFE ihagaze neza kugeza kuri 300 ° C, ariko mumuriro irabora kandi ikarekura imyuka yuburozi cyane: hydrogène fluoride (HF) (korora, pulmonary edema) na perfluoroisobutylene (PFIB) (idafite ibara, impumuro nziza, ~ 10x uburozi burenze fosgene, nta antidote). Nanone umwuka wa karubone, ibisigazwa bya PFOA, na dioxyde de tronc. Ibisumizi bisanzwe byumwotsi ntacyo bikora; koresha ibikoresho byo guhumeka wenyine (SCBA). Ibimenyetso birashobora gutinda.

Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE ikozweho fiberglass) nibyiza byo gushyushya microwave kuko yohereza microwave idakoresheje ingufu, irwanya 260 ° C, kandi ifite ubuso butari inkoni. Mubisabwa harimo matike yo gutekesha microwave, imikandara yumye yumye, imishwarara ya reaction yo gusya imiti, hamwe na microwave popcorn yamashashi. Amanota ya FDA aboneka kubiryo.

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 buruta ubudodo busanzwe. 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.

Ibikoresho byo kurangiza bikoreshwa kumyenda ya fiberglass mbere yo gutwikira PTFE nibyingenzi mubikorwa bya nyuma bya PTFE yubushyuhe bwo hejuru. Ibikoresho byo guhuza organosilane birema ibiraro bya molekuline hagati ya fibre yikirahure idasanzwe na PTFE kama, bikongerera imbaraga ibishishwa kuva kuri <2 N / cm kugeza 4-8 + N / cm. Kuvura neza kandi byongera imbaraga zo kurwanya ubushyuhe (260 ° C +), imikorere ya dielectric, hamwe no kurwanya imiti. Imyenda itavuwe iganisha ku gusiba, kubyimba, no kubaho igihe gito.

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 hamwe.
