Fiberglass umwenda wo kugabanya ubushyuhe nintandaro yambere ya PTFE kaseti ihindagurika. Ku bushyuhe bwa PTFE (360-400 ° C), impungenge zo kuboha zisigaye. Niba bidakumiriwe, imyenda iragabanuka; niba bikumiriwe, guhangayika byihishe bifunze, bigatera kugabanuka nyuma mugihe cyo gukiza (150-200 ° C) no gushyushya-kurangiza. Igisubizo: koresha fiberglass mbere yubushyuhe hamwe na <0.5% kugabanuka kuri 400 ° C, ukuraho imihangayiko isigaye mbere yo gutwikira.

Inkoko muri emulioni ya PTFE ikora imirimo ine yingenzi: guhagarika ihagarikwa (birinda gutuza uduce duto twa PTFE), imyitwarire yo kunanura imisatsi (ubukonje bwinshi kuruhuka, hasi munsi yimyigaragambyo yo gutwikira byoroshye), kugenzura ubujyakuzimu bwimbitse (igenga imizigo yipakira kumyenda ya fiberglass), hamwe nuburinganire bwa firime (birinda gucika mugihe cyo kumisha). Icyangombwa gikenewe: umubyimba ugomba kubora burundu kuri ~ 380 ° C yubushyuhe, hasigara ivu rya zeru kugirango habeho isuku no gutwika amashanyarazi.

Aokai PTFE yerekanye ibicuruzwa byuzuye muri APFE Shanghai 2026 (Booth 6T602, Hall 6). Ibicuruzwa byerekanwe birimo kaseti ya PTFE yongerewe imbaraga, firime nziza ya PTFE, amanota arwanya static, hamwe n’umukandara woherejwe n'ubushyuhe bwo hejuru - bikubiyemo gutunganya ibiryo, PV lamination, bateri ya lithium, ibikoresho bya elegitoroniki, hamwe no gupakira. Imurikagurisha rizatangira ku ya 26 Kamena.Ibicuruzwa byose bishyigikira ibisobanuro byihariye.

Ubuvuzi bwa PTFE kubwo guhuza bifashisha uburyo bubiri bwingenzi: gushonga ubushyuhe bwo hejuru (guhangana nikirere cyiza, imbaraga za MPa 9.5 hamwe na agent ihuza, ariko ikarekura imyuka yubumara) hamwe na sodium-naphthalene (5 MPa guhita ifata, idirishya ryamasaha 24-48, imyanda iteje akaga). Hitamo ukurikije kugenzura ibidukikije nigihe kirekire nibikorwa bigufi.

Gupima ubwiza bwa PTFE burimo ibipimo bitandatu byingenzi: ibirimo bikomeye (60 ± 2% kuri T / FSI 067-2021), pH (9.0-11.0), ingano yubunini bwagabanijwe (laser diffaction / DLS), viscosity (12-30 mPa · s kuri 25 ° C), gutuza (centrifugal, ubushyuhe, gukonjesha-thaw), no kugaragara. Aka gatabo gakubiyemo uburyo busanzwe bwo gupima kuri buri kintu.

Gukoresha PTFE yubushyuhe bwo hejuru cyane hejuru yumurongo uhetamye kandi udasanzwe udafite ibibyimba no gukubita impande zose, inzira isanzwe irakenewe, harimo kwitonda neza, ubuhanga bwo gukoresha umwuga hamwe ningamba zifatika zifasha. Muri byo, substrate kwitegura nintambwe ikomeye cyane, igena hafi 70% yingaruka zanyuma.

Kuruhande rwamabwiriza agenga ibidukikije arushijeho gukomera, emulioni ya PFOS / PFOA idafite PTFE nigicuruzwa cyazamuwe cyakozwe kugirango gisimbuze inzira gakondo ya PFOA irimo polymerisiyasi. Ikomeza ibintu byingenzi bya PTFE mugihe izamura cyane ibidukikije byumutekano numutekano wubuzima.

Coefficente yo kwagura ubushyuhe bwa PTFE yubushyuhe bwo hejuru ntabwo ari agaciro gahamye. Iguma hasi cyane mubushyuhe bwicyumba kugeza kuri 100 ° C (hafi 0.5 × 10⁻⁵ / ° C), ariko ikazamuka cyane mugihe cy'ubushyuhe bwinshi.

Nkumushinga wumwuga wimyenda yubushyuhe bwo hejuru ya PTFE, Jiangsu Aokai Ibikoresho bishya bisangiye tekinike yibanze. Kugira ngo wirinde burrs, gusibanganya no gutandukana kurwego mugihe cyo gutemba, ni ngombwa kugenzura buri gihe ibintu bine byingenzi: ibikoresho byo gukata, ibikoresho, ibikoresho fatizo an

Nkumushinga wumwimerere wa kaseti ya PTFE yubushyuhe bwo hejuru, Jiangsu Aokai Ibikoresho bishya rero birasobanura ingaruka zuburyo bwo gukonjesha nigipimo cyo gukonjesha kumikorere ya kaseti ya PTFE yakize.I. Ibyingenzi bya Crystallisation ya PTFE Ibiranga no gukonjesha igipimo cyo gukonjesha PTFE su
