Uburyo Ubushyuhe bugira ingaruka kumashanyarazi ya PTFE Imyenda yo hejuru

Imyenda ya PTFE yubushyuhe bwo hejuru ikoreshwa cyane nkumuriro wamashanyarazi mugukoresha insinga, ibice bya transformateur, guhinduranya moteri, hamwe numuyoboro mwinshi. Ariko ubushyuhe burahinduka - kuva ubukonje bukonje kugeza ubushyuhe bukabije - hindura imyitwarire yacyo. Urashobora kwishingikiriza kumyenda ya PTFE kuri 200 ° C? Bigenda bite hejuru ya 260 ° C?

Igisubizo kirasobanutse. Imiterere ya molekulire ya PTFE itanga ubwiganze buhebuje mubikorwa byayo byinshi, ariko kurenga 260 ° C bitera kwangirika bidasubirwaho. Mugihe ubushyuhe bukonje butezimbere amashanyarazi, bituma igifuniko kivunika.

Aokai PTFE yagerageje imiterere yimiterere yubushyuhe bukabije. Iyi ngingo igabanya imikorere mubice bitatu: imikorere isanzwe (-180 ° C kugeza 260 ° C), hejuru cyane (> 260 ° C), nubushyuhe buke (<0 ° C), hamwe namakuru yingenzi kubyerekeranye no kurwanya, imbaraga za dielectric, ningaruka zifatika.

Urwego rusanzwe rukora: -180 ° C kugeza 260 ° C - Gukingira cyane

Muri uru rwego, umwenda wo hejuru wa PTFE ukomeza amashanyarazi adasanzwe kandi ahamye - inyungu nyamukuru ishyigikira ikoreshwa ry’inganda.

1. Umubumbe & Ubuso Kurwanya

Mechanism: Kurwanya bigabanuka kuburyo bugereranije nubushyuhe bwiyongera kuko ubushyuhe bwo hejuru bwongera ingufu zumuriro wumunyururu wa PTFE kandi byihutisha kwimuka kwabatwara umwanda. Nubwo, no kuri 200 ° C, PTFE iruta plastiki yubuhanga bwinshi mubushyuhe bwicyumba.

Icyitonderwa kubirwanya hejuru: Kurwanya ubuso birashoboka cyane kubushuhe bwibidukikije. PTFE ni hafi ya hygroscopique; Ubushyuhe bwo hejuru bugenda bugabanuka ku bushyuhe bwo hejuru, bugatanga ubushyuhe butajegajega kuruta mu cyumba cy’ubushyuhe bwinshi.

2. Imbaraga za Dielectric (Umuvuduko wamashanyarazi)

• Kugabanuka uko ubushyuhe buzamuka. Kwiyongera kwa molekuliyumu yubushyuhe ituma ibintu byangirika kwangirika kwumuriro.

• Kuva ubushyuhe bwicyumba kugera kuri 200 ° C, imbaraga za dielectric zigihe gito zigabanuka hafi 20% –40%.

• Nubwo bimeze bityo, umwenda uhebuje ufite uburebure bwa mm 0.1 uracyashobora kwihanganira kilovolt nyinshi (cyangwa kilovili icumi kumanota manini) kuri 200 ° C - ubushobozi bwo kubika neza.

3. Dielectric Constant & Dissipation Factor - Ihindagurika Rito

Impamvu ibi bifite akamaro: Imiterere ya molekile ya PTFE hamwe na polarisiyasi ya ultra-hasi yemeza ko itumanaho rihoraho hamwe nubushyuhe bukabije bwumuriro munsi yumurongo mwinshi & serivisi yubushyuhe bwo hejuru. Ibi byujuje ibyangombwa PTFE nkibikoresho byiza-byihuta byifashishwa bya RF na microwave.

Aokai PTFE imyenda yubushyuhe bwo hejuru igaragazwa nabakiriya kugirango bahindure insimburangingo nyinshi kubera Dk ihamye (2.05 ± 0.05) hamwe na tan-ultra-low tanδ (0.0002-0.0005) hejuru ya -50 ° C kugeza 200 ° C. Dutanga raporo yikizamini cyumutungo wa dielectric tubisabwe.

Ikirere Cyinshi-Ubushyuhe bukabije: Hejuru ya 260 ° C - Gutesha agaciro bidasubirwaho

Kurenza igihe kirekire PTFE yemerewe ubushyuhe bwa serivisi itera kwangirika kudasubirwaho kumubiri na chimique - ntabwo ibintu bihindagurika.

Umuburo wingenzi: Nubwo umwenda wibanze wa fiberglass wihanganira 550-750 ° C mbere yo koroshya, fiberglass yambaye ubusa idahita yorohereza amazi nyuma yo gutwikwa kwa PTFE kandi ntishobora kwigenga kugirango ikoreshwe n’umuriro mwinshi.

Urwego rwo hasi-Ubushyuhe: Munsi ya 0 ° C - Kunoza amashanyarazi ariko Kumashanyarazi

Ibyingenzi byingenzi: Nubwo amashanyarazi yongerewe ingufu mubushyuhe buke, igifuniko cya PTFE kiba cyoroshye. Kubikoresho bya kirogenike (urugero, imirongo ya azote yuzuye, magnesi zirenze urugero), menya neza ko umwenda udaterwa no kunama gukabije cyangwa guhangayikishwa munsi ya -79 ° C. Iyo bimaze gucika, ubunyangamugayo butakara hatitawe kumashanyarazi.

Incamake - Guma muri 260 ° C kugirango ukingire neza

Muri make , mubushuhe bukomeza busabwa (≤260 ° C), ubushyuhe butera ingaruka zitari nziza kuri PTFE yubushyuhe bwo hejuru bwumuriro w'amashanyarazi. Kurwanya amajwi bikomeza kuba hejuru ya 10⊃1; ⊃3; Ω · cm kuri 200 ° C; guhora dielectric iguma kuri 2.0-2.1; ibintu byo gutandukana munsi ya 0.001. Ibi bituma PTFE imwe mubikoresho bihamye byubushyuhe bwo hejuru buraboneka - cyane cyane bifite agaciro gakoreshwa cyane aho izindi polymers zigira igihombo gikomeye.

Iyo bimaze gushyuha birenze 260 ° C, kunanirwa kwizana bitangirana no koroshya imashini no guhinduka, amaherezo bigahinduka amashanyarazi yuzuye. Hejuru ya 400 ° C, karubone ikora inzira zihoraho. Munsi ya 0 ° C, ibikoresho byamashanyarazi biratera imbere, ariko ubukana bwubukanishi bushobora gutobora igifuniko.

Ukeneye umwenda wa PTFE ufite ubushyuhe bwo hejuru hamwe nubwishingizi bwimiterere yubushyuhe bwawe? Aokai PTFE itanga amakuru yuzuye ya dielectric kuva kuri 70 ° C kugeza 260 ° C. Twandikire hamwe nubushyuhe bwawe bukora, voltage, nibisabwa inshuro.

Amakuru ya tekiniki yavuzwe haruguru yatanzwe na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.

Niba ukeneye ibindi bisobanuro bya tekiniki, ibisubizo byabigenewe, hamwe nu musaruro wihariye wibicuruzwa byuzuye birimo imyenda yubushyuhe bwo hejuru bwa PTFE, kaseti ya PTFE, umukandara wa PTFE mesh, umukandara wimashini udahuza, umukandara umwe wa PTFE hamwe nigitambaro cyo hejuru cy’ubushyuhe bukabije hamwe nigitambaro cya fiberglass , nyamuneka twandikire:

• Bwana Guo: +86 18944819998

• Bwana Liu: +86 13705266308

Twubahiriza ubunyangamugayo nubunyangamugayo kugirango dutange igisubizo kimwe cyihariye cyinganda zinganda hamwe nibitekerezo nyuma yo kugurisha.
