Momwe Kutentha Kumakhudzira Kuyika kwa Magetsi kwa PTFE High-Temperature Nsalu

Nsalu ya PTFE yotentha kwambiri imagwiritsidwa ntchito kwambiri ngati kutchinjiriza kwamagetsi pama waya, zigawo za thiransifoma, ma windings a mota, ndi ma frequency okwera kwambiri. Koma kutentha kumasintha - kuchokera ku kuzizira mpaka kutentha kwambiri - kumasintha khalidwe lake lotetezera. Kodi mungadalire nsalu ya PTFE pa 200 ° C? Chimachitika ndi chiyani pamwamba pa 260 ° C?

Yankho lake ndi losavuta. Mapangidwe a ma cell a PTFE amapangitsa kuti ikhale yotsekereza kwambiri pamagawo ake ambiri ogwiritsira ntchito, koma kupitilira 260°C kumayambitsa kuwonongeka kosasinthika. Ndipo ngakhale kuti kuzizira kumawonjezera mphamvu zamagetsi, kumapangitsa kuti nsaluyo ikhale yolimba.

Aokai PTFE yayesa katundu wotchinjiriza pa kutentha kwambiri. Nkhaniyi ikugawaniza magwiridwe antchito m'magulu atatu: magwiridwe antchito (-180 ° C mpaka 260 ° C), okwera kwambiri (> 260 ° C), ndi kutentha kotsika (<0 ° C), okhala ndi data yayikulu pa resistivity, mphamvu ya dielectric, ndi zotsatira zake.

Nthawi Zonse Ntchito: -180 ° C mpaka 260 ° C - Kuyimitsa Kwambiri Kwambiri

Munthawi imeneyi, nsalu zotentha kwambiri za PTFE zimasunga bwino komanso zokhazikika zotchinjiriza magetsi - phindu lalikulu lomwe limathandizira kufalikira kwamakampani.

1. Volume & Surface Resistivity

Mechanism: Resistivity imatsika pang'onopang'ono ndi kutentha kwapamwamba chifukwa kutentha kwapamwamba kumawonjezera kusuntha kwa ma cell a PTFE ndikufulumizitsa kusamuka kwa onyamula zonyansa. Komabe, ngakhale pa 200 ° C, PTFE imaposa mapulasitiki ambiri aumisiri kutentha.

Zindikirani pa kukana kwapamtunda: Kukana kwa pamwamba kumakhudzidwa kwambiri ndi chinyezi chozungulira. PTFE ndi pafupifupi sanali hygroscopic; Chinyontho cha pamwamba chimasanduka nthunzi pa kutentha kokwera, kumapereka chitetezo chokhazikika chapamwamba kuposa m'chipinda chokhala ndi chinyezi chambiri.

2. Mphamvu ya Dielectric (Kuwonongeka kwa Voltage)

• Imachepa kutentha kumakwera. Kuchuluka kwa matenthedwe a maselo kumapangitsa kuti zinthuzo zikhale pachiwopsezo cha kuwonongeka kwa magetsi.

• Kuchokera kutentha mpaka 200 ° C, mphamvu ya dielectric yaifupi imatsika pafupifupi 20% -40%.

• Ngakhale zili choncho, nsalu yamtengo wapatali yozungulira 0.1 mm yokhuthala imapirirabe ma kilovolts angapo (kapena makumi a kilovolts pamagulu okulirapo) pa 200 ° C - mphamvu yotchinjiriza yolimba imasungidwa.

3. Dielectric Constant & Dissipation Factor - Kusinthasintha Kochepa

Chifukwa chiyani izi zili zofunika: PTFE yofananira kwambiri ndi ma molekyulu a PTFE komanso polarization yotsika kwambiri imatsimikizira kufalikira kwa ma sigino okhazikika komanso kutulutsa kutentha kocheperako pansi pa ntchito yothamanga kwambiri komanso yotentha kwambiri. Izi zimayenereza PTFE ngati chinthu choyenera chotchingira ma frequency amtundu wa RF ndi ma microwave.

Nsalu ya Aokai PTFE yotentha kwambiri imatchulidwa ndi makasitomala chifukwa cha kutentha kwa thiransifoma yothamanga kwambiri chifukwa cha kukhazikika kwa Dk (2.05±0.05) ndi tanδ yotsika kwambiri (0.0002-0.0005) kudutsa -50°C mpaka 200°C osiyanasiyana. Timapereka malipoti oyesa katundu wa dielectric tikafunsidwa.

Kutentha Kwambiri Kwambiri: Pamwamba pa 260 ° C - Kuwonongeka Kosasinthika

Kupitilira kutentha kwa nthawi yayitali kwa PTFE kumayambitsa kuwonongeka kwa thupi ndi mankhwala - osati kusinthika kwa katundu.

Chenjezo lofunika: Ngakhale nsalu yoyambira ya fiberglass imatha kupirira 550-750 ° C isanafewe, galasi losavundidwa la fiberglass limayamwa mosavuta chinyontho pambuyo pakulephereka kwa PTFE ndipo silingathe kudziyimira pawokha pakutchingira kwamagetsi.

Kutentha Kwapang'ono: Pansi pa 0 ° C - Kuwongoleredwa kwa Magetsi koma Makina Osasunthika

Chotengera chofunikira: Ngakhale kutenthedwa kwamagetsi kumatenthedwe otsika, zokutira za PTFE zimakhala zolimba. Pogwiritsa ntchito ma cryogenic (mwachitsanzo, mizere ya nayitrogeni yamadzimadzi, maginito apamwamba), onetsetsani kuti nsaluyo simapindika kapena kupsinjika kwamakina pansi -79 ° C. Akaphwanyidwa, kukhulupirika kwa insulation kumatayika mosasamala kanthu za mphamvu zamagetsi.

Chidule Chachidule - Khalani Mkati mwa 260 ° C Kuti Mukhale ndi Insulation Yodalirika

Mwachidule , mkati mwa kutentha kosalekeza kovomerezeka kogwira ntchito (≤260°C), kutentha kumapangitsa kuti PTFE iwononge magetsi a nsalu yotentha kwambiri. Kusintha kwa voliyumu kumakhalabe pamwamba pa 10⊃1;⊃3; Ω·cm pa 200°C; dielectric nthawi zonse amakhala pa 2.0-2.1; dissipation factor pansi pa 0.001. Izi zimapangitsa PTFE kukhala imodzi mwazinthu zokhazikika kwambiri zotenthetsera zotenthetsera zomwe zilipo - makamaka zofunika pamapulogalamu apamwamba kwambiri pomwe ma polima ena amawonongeka kwambiri.

Akatenthedwa kwambiri kupitirira 260 ° C, kulephera kwa kutchinjiriza kumayamba kuchokera pakufewetsa ndi kusinthika kwa makina, kenako kumasanduka kuwonongeka kwathunthu kwa magetsi. Pamwamba pa 400 ° C, carbonization imapanga njira zokhazikika. Pansi pa 0°C, mphamvu zamagetsi zimakhala bwino, koma kuwonongeka kwa makina kumatha kusokoneza zokutira.

Mukufuna nsalu yotentha kwambiri ya PTFE yokhala ndi zotsimikizika zotchinjiriza pazosiyanasiyana zanu? Aokai PTFE imapereka deta yonse yoyezetsa dielectric kuchokera -70°C mpaka 260°C. Lumikizanani nafe ndi kutentha kwanu, ma voltage, ndi ma frequency omwe mukufuna.

The pamwamba luso deta operekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mungafune zina mwaukadaulo, mayankho ogwiritsira ntchito, ndi kupanga makonda azinthu zonse kuphatikiza nsalu yotentha kwambiri ya PTFE, tepi yomatira ya PTFE, lamba wa PTFE mauna otumizira, lamba wamakina osakanizika, nsalu ya PTFE yokhala ndi mbali imodzi ndi cholumikizira chosagwira kutentha kwambiri & fiberglass , chonde titumizireni:

• Bambo Guo: +86 18944819998

• Bambo Liu: + 86 13705266308

Timatsatira ukatswiri ndi kukhulupirika kuti tipereke mayankho amakampani okhazikika komanso chithandizo choganizira pambuyo pogulitsa.
