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.

PTFE yubushyuhe bwo hejuru ikorera inganda za PV mubikorwa bibiri bitandukanye: inzira ikoreshwa (irinda EVA kurengerwa na laminator, mask yo kugurisha) hamwe no kuramba kuramba (gupfunyika busbar, guhuza agasanduku). Kugirango ukoreshe imbere imbere, kaseti igomba kunyura IEC 61215: 1000-2000h ubushyuhe butose, UV, gusiganwa ku magare (-40 ° C kugeza + 85 ° C), hamwe na silicone PSA no kugabanuka <1%.

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.

PTFE yubushyuhe bwo hejuru ikoreshwa kumyuma ifunga ubushyuhe hamwe nudupapuro twa kashe itanga indangagaciro enye zingenzi: irinda ifumbire ya pulasitike yashonze (ikuraho igihe cyo hasi), irinda kashe ihenze ipfa, ihuza ubushyuhe / umuvuduko wa kashe ihoraho, kandi igabanya ubukana bwa firime. Birasabwa gufata kaseti ya fibre (0.13-0,25 mm) hamwe na silicone PSA (≥260 ° C). Anti-static umukara kaseti kumirongo yihuta.

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.

Inzitizi y'amazi ya barrière ya PTFE ifata kaseti igenwa cyane cyane nubusembwa (micropores, microcrack, fibre fibre) aho kuba hydrophobicity ya PTFE. Filime nziza ya PTFE itanga gusa WVTR yo hagati. Ibice byinshi byuzuzanya hamwe na lamellar yuzuza (mika, ibirahuri by'ibirahure) bitera labyrint, bigabanya cyane kwanduza imyuka. Kugirango ushireho ubuhehere bwinshi, vuga 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.

Kurwanya creep ya PTFE yubushyuhe bwo hejuru yubushyuhe munsi yumutwaro muremure uhoraho (cyane cyane kuri 200-260 ° C) bigenwa nimpamvu ebyiri: silicone PSA ihuza ubwinshi (guhuza kwinshi birinda gutemba) hamwe nubwoko bwa substrate (fiberglass-yongerewe imbaraga PTFE irwanya ubukonje bukonje; Ibifunga bidahuye birananirana vuba mubushyuhe bwinshi. Gufata neza cyane byongera ibyago byo kunyerera.
