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 byonyine (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 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.

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.

Ububiko bwa fibre yububiko - busanzwe, twill, cyangwa satine - bigira ingaruka zikomeye kumiterere ya PTFE yubushyuhe bwo hejuru. Ububoshyi bwa Satin butanga imbaraga zo kurira cyane (2-3x igaragara) kandi byoroshye, nibyiza kugoreka imbaraga. Ububoshyi bwibibaya butanga icyerekezo cyiza kandi gihamye, gikwiranye na static progaramu. Twill iringaniza imitungo yose kugirango ikoreshwe muri rusange.

Uburinganire bwimyenda ya PTFE yubushyuhe bwo hejuru bugenwa nimpamvu enye: gutondekanya (ingano ya 0.15-0.35 μ mm, viscosity, ibintu bikomeye), gutwikira & gucumura (gutwikira icyuma gikundwa kuburinganire), ubuziranenge bwibisobanuro (kuboha, kubanza kubivura), hamwe nibidukikije (20-25 ° C, <60% RH). Dip + blade ikomatanyirijwe hamwe iringaniza kwinjira no kugaragara neza.
