Sei Girazi Fiber Mucheka Iri Pasi Pakudonhedza Waxing Isati Yaiswa nePTFE Emulsion? Chii chinonzi Principle?

Senyanzvi yekugadzira machira ePTFE akakwira-tembiricha, Aokai New Materials inoitisa kurapa kwepamusoro-tembiricha pajira regirazi fiber. Isati yaiswa nePTFE (Polytetrafluoroethylene) emulsion, jira regirazi refayibha rinoita dewaxing uye degumming kubvisa sizing agents (machira ekubatsira) pane fiber pamusoro. Aya anobatsira anoshandira kuunganidza, mafuta uye kudzivirira panguva yekudhirowa kwefiber uye kuruka. Zvisinei, kana isina kubviswa, ivo vanozokanganisa zvakanyanya kuumbwa kwemhando yePTFE uye girazi fiber. Nheyo idzi dzinonyanya seizvi:

1. Bvisa Low Surface Energy Substances uye Kuvandudza Wettability

Parafini, mafuta ekuzora uye zvimwe zvikamu mu saizi ejenti zvakaderera pamusoro pesimba zvinhu. Kana ikachengetwa, iyo PTFE emulsion (ine kuderera kwepasi tension asi zvakasimba zvinodiwa) haigoni kupararira zvakaenzana pagirazi fiber pamusoro, zvichikonzera kukanganisa kwakadai se craters uye maziso ehove. Kuburikidza nepamusoro-tembiricha yekuchenesa kupisa kana kuchenesa kuchenesa, zvinosvibisa zvinobviswa uye simba repamusoro regirazi fiber rinowedzerwa, zvichiita kuti kunyorova kwakazara nePTFE.

2. Kudzivirira Carbonization uye Delamination Panguva Yepamusoro-Tembiricha Sintering

Tembiricha yekupisa yePTFE yakakwira kusvika 360–380°C. Parafini yakasara kana epoxy adhesives pamusoro pegirazi faibha pamusoro inopenya patembiricha yakakwira kudaro, ichigadzira zvimedu zvitema kana gasi. Izvi hazvingosvibisi svikiro (zvichikanganisa dielectric properties mu-high-frequency copper-clad laminates) asi, zvakanyanya, iyo carbonized layer inogadzira chimiro chisina simba, ichideredza zvakanyanya simba rekubatanidza pakati pePTFE negirazi fiber uye kukonzera delamination yezvakagadzirwa zvinhu.

3. Gadzira Yakasimba 'Mechanical Anchoring' Mhedzisiro

Dewaxing yemhando yepamusoro uye degumming (kunyanya kupisa-kupisa kupisa) kunopfuura 'kuchenesa'. Sezvo organic zvinhu zvichibviswa, iyo girazi fiber pamusoro inoiswa zvishoma kuti igadzire mamicropores kana kufumura mamwe mapoka e silanol (-OH). Izvi zvinogadzira mamiriro ezvekuzotevera coupling agent coating (semuenzaniso, phenyl silane), zvichibvumira PTFE kuumba kemikari zvisungo kana zvepanyama anchoring poindi negirazi faibha kuburikidza nemaajenti ekubatanidza - kushandura 'kupfeka' kuri nyore kuita 'bonding' yakasimba.

4. Dzivisa Kuparara kweInterfacial Dielectric Properties

Mumashandisirwo epamusoro-soro akadai se-high-frequency uye high-speed copper-clad laminates, zvakasara zvepolar organic substances (wax, gum) zvakanyanya kuwedzera dielectric kurasikirwa pasi pekushisa kwepamusoro uye nguva yakawanda. Dewaxing uye degumming inovimbisa iyo girazi fiber-PTFE inoumbwa inochengetedza yakaderera dielectric kugara uye dielectric kurasikirwa.

Mukupfupisa, chinangwa chikuru chekurapa uku ndechekubvisa maratidziro asina kusimba uye kuve nechokwadi chekuti PTFE, yakaderera pamusoro pesimba zvinhu, inowana yakakwana yekunyorova uye yakakwirira-simba bonding pane yakachena, yepamusoro-pamusoro-simba regirazi fiber.

Ruzivo rwuri pamusoro rwunopihwa neJiangsu Aokai New Materials Technology Co., Ltd.

Kuti uwane ruzivo rwakadzama, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere - zvinosanganisira PTFE yakakwirira-tembiricha machira, PTFE yakakwirira-tembiricha matepi, PTFE yakakwirira-tembiricha mesh mabhandi, seamless mabhandi emichina yekubatanidza, jira rimwechete-sided PTFE, yakakwirira-tembiricha inodzivirira girazi, machira akasununguka anotenderedza - faibha isingagadzirwe girazi isu:
