N'chifukwa chiyani Glass Fiber Nsalu Imayikidwa pa Dewaxing Musanalowe m'mimba ndi PTFE Emulsion? Kodi Mfundo Yofunika Kwambiri Ndi Chiyani?

Monga katswiri wopanga nsalu za PTFE zotentha kwambiri, Aokai New Materials amachita chithandizo cha kutentha kwambiri pansalu yamagalasi. Pamaso impregnation ndi PTFE (Polytetrafluoroethylene) emulsion, galasi CHIKWANGWANI nsalu akukumana dewaxing ndi degumming kuchotsa sizing wothandizila (nsalu wothandiza) pa CHIKWANGWANI padziko. Zothandizirazi zimagwira ntchito yomanga mtolo, kuthira mafuta ndi chitetezo panthawi yojambula ndi kuluka. Komabe, ngati sichichotsedwa, iwo adzasokoneza kwambiri khalidwe la PTFE ndi galasi fiber. Mfundo zake ndi izi:

1. Chotsani Zida Zamagetsi Zochepa Pamwamba ndi Kupititsa patsogolo Kunyowa

Paraffin, mafuta opaka mafuta ndi zinthu zina zopangira ma saizi ndi zinthu zotsika kwambiri padziko lapansi. Ngati anapitiriza, ndi PTFE emulsion (ndi otsika padziko mavuto koma okhwima zofunika) sangathe kufalikira wogawana pa galasi CHIKWANGWANI pamwamba, chifukwa mu zolakwika monga craters ndi maso nsomba. Kupyolera mu kuyeretsa kwa kutentha kwapamwamba kwambiri kapena kuyeretsa zosungunulira, zonyansa zimachotsedwa ndipo mphamvu ya pamwamba ya galasi fiber imachulukitsidwa, kupangitsa kuti kunyowetsa kwathunthu ndi PTFE.

2. Pewani Carbonization ndi Delamination Pa High-Temperature Sintering

Kutentha kwa sintering kwa PTFE ndikokwera kwambiri mpaka 360–380°C. Zotsalira za parafini kapena zomatira za epoxy pagalasi zomatira zimadzaza ndi kutentha kotere, kutulutsa tinthu takuda kapena mpweya. Izi sizimangowononga sing'anga (zokhudza dielectric katundu mu high-frequency copper-clad laminates) koma, mozama kwambiri, mpweya wa carbonized umapanga mawonekedwe ofooka, kuchepetsa kwambiri kugwirizanitsa mphamvu pakati pa PTFE ndi galasi fiber ndikuyambitsa delamination ya zinthu zophatikizika.

3. Khazikitsani Mphamvu Yamphamvu ya 'Mechanical Anchoring'.

Kuwotcha kwapamwamba kwambiri ndi kupukuta (makamaka kutentha kwa kutentha kwambiri) ndikoposa 'kuyeretsa' kokha. Pamene zinthu za organic zimachotsedwa, galasi la fiber pamwamba limakhazikika pang'ono kupanga ma micropores kapena kuwulula magulu ambiri a silanol (-OH). Izi zimapanga zinthu zomangirira wotsatira (mwachitsanzo, phenyl silane), kulola PTFE kupanga zomangira zamankhwala kapena zomangira zakuthupi ndi ulusi wagalasi pogwiritsa ntchito ma coupling agents - kusintha 'kutchingira' kosavuta kukhala 'kumanga' kolimba.

4. Pewani Kuwonongeka kwa Zida Zogwiritsa Ntchito Dielectric

M'mapulogalamu apamwamba kwambiri monga laminates okwera kwambiri komanso othamanga kwambiri, zinthu zotsalira za polar organic (sera, chingamu) zimawonjezera kutaya kwa dielectric pansi pa kutentha kwakukulu komanso nthawi zambiri. Dewaxing ndi degumming zimatsimikizira kuti galasi fiber-PTFE composite imakhalabe yotsika kwambiri ya dielectric mokhazikika komanso kutayika kwa dielectric.

Mwachidule, cholinga chachikulu cha mankhwalawa ndikuchotsa magawo ofooka a mawonekedwe ndikuwonetsetsa kuti PTFE, zinthu zotsika kwambiri zamphamvu, zimakwaniritsa kunyowetsa bwino komanso kulumikizana kwamphamvu kwambiri pamagalasi oyera, apamwamba kwambiri.

Zambiri pamwambapa zimaperekedwa ndi Jiangsu Aokai New Materials Technology Co., Ltd.

Kuti mumve zambiri, mawonekedwe ogwiritsira ntchito ndi mayankho makonda azinthu zathu zonse - kuphatikiza nsalu za PTFE zotentha kwambiri, matepi a PTFE, malamba a PTFE apamwamba, malamba osasunthika pamakina omangira, nsalu ya PTFE ya mbali imodzi, magalasi osamva kutentha kwambiri, magalasi osamva kutentha kwambiri, magalasi osasunthika kwambiri - chonde mverani magalasi osagwirizana ife:
