I-Jiangsu Aokai New Materials, umkhiqizi ochwepheshe wendwangu ye-PTFE eshisa kakhulu, unikeza isingeniso esigcwele. Inqubo yokumithisa indwangu ye-fiberglass ene-PTFE dispersion iwubuchwepheshe obuyisisekelo ukumboza nokufaka i-polytetrafluoroethylene ngokulinganayo ku-fiberglass substrate, ukwakha izinto eziyinhlanganisela ezibonisa ukumelana nokushisa okuphezulu, ukwahlukanisa ugesi kanye nokusebenza okungeyona induku. Imikhiqizo enjalo isetshenziswa kabanzi kuma-laminates ane-copper-clad high-frequency, amabhande okuthutha angagxili okushisa aphezulu, izinto zokwakha ulwelwesi lwezakhiwo nezinye izinkambu.
Inqubo eyisisekelo ephelele inezinyathelo eziyisikhombisa ezibalulekile kanjena:
1. I-Fiberglass Fabric Pretreatment (I-Dewaxing / Desizing)
Lesi isinyathelo esibaluleke kakhulu sokwelashwa kwangaphambili. I-ejenti yokulinganisa izindwangu (ikakhulukazi i-wax kapharafini, okuphuma kusitashi) imbozwe emicu ye-fiberglass ngesikhathi sokwaluka; ukususwa okungaphelele kuzokhinyabeza kakhulu ukuhlangana kobuso phakathi kwe-PTFE nemicu yengilazi.
· Indlela yokwelapha eyinhloko: Indwangu iqhubeka ngokudlula esithandweni sokushisa esishisayo ukuze ikhishwe nge-thermal dewaxing ku-350 ~ 400°C, i-oxidizing ngokugcwele futhi ibola wonke ama-agent e-organic sizeing.
· Ukuphathwa kokulandelela: Indwangu ekhishwe ngewax ipholiswa phansi, ngezinye izikhathi ihlanjululwe ngamanzi ahlanzekile noma izincibilikisi zamakhemikhali ukuze kuqedwe umlotha osalayo, bese yomiswa ukuze kutholakale indwangu emhlophe engenalutho elungele ukumiliselwa.
· Impahla eluhlaza: Ukuhlakazeka kwe-PTFE okugxilisiwe okunokuqukethwe okuqinile okujwayelekile okungaba ngu-60%.
· Inqubo yokuxuba: Nciphisa ukuhlakazeka kwesitoko ngamanzi akhishwe nge-deionized kuya ekugxiliseni okuhlosiwe (40%–55%) ngokusekelwe ekulayishweni kwenhlaka edingekayo kanye ne-viscosity yokufaka. I-surfactant efanelekile yengezwa ukuthuthukisa ukusebenza kokumanzisa ku-fiberglass; i-thickener ingase ifakwe ukulungisa i-viscosity uma kunesidingo.
3. Ukukhulelwa
Okuhlosiwe okuyinhloko wukungena okugcwele kwe-PTFE emulsion kuma-fiber bundles nama-interstices endwangu elukiwe.
1. Indlela ye-Dip-Squeeze (Eyamukelwa kabanzi): Indwangu iholwa ngamarola wokucwiliswa ukuze icwiliswe ngokuphelele ethangini le-emulsion, bese idlula kuma-roller wokuminyanisa. Isisindo sokugqoka silawulwa ngokulungisa i-roller nip pressure ukuze ikhiphe i-emulsion eyeqile futhi isabalalise inhlaka ngokufanayo.
2. I-Doctor Blade Coating: I-emulsion isakazwa phezu kwendwangu ngokusebenzisa izindwani zensimbi, ezilungele ukusabalalisa okuphezulu kwe-viscosity.
4. Ukomisa
Indwangu egxilile ingena kuhhavini wokomisa izinga lokushisa eliphansi osebenza ku-100~150°C.
· Injongo: Hambisa amanzi kancane kanye nama-surfactants ayingxenye, wakhe ifilimu eyomile engena-tacky yezinhlayiya ze-PTFE endaweni yefayibha.
· Inothi lokulawula izinga lokushisa: Izinga lokushisa eliphakeme kakhulu lizokwenza ngokushesha ifilimu elingaphezulu eliminyene, livale umswakamo wangaphakathi ohwamukayo wenze izimbobo namabhamuza.
5. I-Sintering (Thermal Curing)
Indwangu eyomile ifakwa ngokushesha esithandweni sokushisa esisezingeni eliphezulu ukuze iphathwe ngokushisisa ku-360~390°C (kufika ku-400°C kwamanye amabanga).
· Indlela yokwenza: I-PTFE iyi-polymer ye-thermoplastic. Emazingeni okushisa angaphezulu kakhulu kwephuzu lawo lokuncibilika (327°C), izinhlayiya ze-PTFE ziyancibilika, zigeleze futhi ziphume izinga ukuze zenze ifilimu eqhubekayo, kuzuzwe ukuhlobana kwemishini nokunamathela ngezindawo ze-fiberglass.
· Ukwehlukaniswa kwesiteji: Indawo yokucwilisa ihlukaniswe yaba irempu yokushisisa, izinga lokushisa elingashintshi le-sintering kanye nezingxenye zokupholisa ukuze kuqinisekiswe ukuhlangana kwezinhlayiyana okuphelele ngaphandle kokuwohloka kokushisa.
6. Multi-Cycle Impregnation & Sintering
Umjikelezo we-impregnation-sintering owodwa ukhiqiza kuphela ukunamathela okuzacile kakhulu okujwayele ukuba namaphutha emigodini. Ukuze ufinyelele ukujiya okuhlosiwe okuhlosiwe kanye nokuqukethwe kwe-resin (isb, 45%–65% ukulayishwa kwe-resin kuma-laminate substrates anemvamisa ephezulu ye-copper-clad), ukulandelana okugcwele kokumiliselwa → ukomiswa → ukucwiliswa kuphindaphindwa izikhathi ezi-2 kuya kwezi-4 noma ngaphezulu. Umjikelezo ngamunye uqhubeka ugcwalisa izikhala zefayibha futhi andise ukujiya kokunamathela, ekugcineni kwakheke ishidi lenhlanganisela eliminyene elingenazimbobo.
7. Ngemva Kokwelashwa & Ukugoqa
1. Ukuguqulwa kobuso: Ngemva kokudlula kokugcina kwe-sintering, ukwelashwa kwe-corona noma ikhemikhali ye-sodium-naphthalene etching ingasetshenziswa ukuze kuthuthukiswe ukunamathela kwendawo ngaphandle kokulimaza i-substrate, kube lula ukuvala ithusi okulandelayo noma ukumbozwa kwesibili.
2. Ukunquma unqenqema nokusonteka: Imiphetho yendwangu isikwa iqonde, bese indwangu eqediwe ilinyazwe kahle umshini wokuthatha.
3. Ukuhlolwa kwekhwalithi: Ukuhlolwa okuphelele kwemikhiqizo eqediwe kufaka phakathi isisindo esiyisisekelo, ukujiya, amandla aqinile, amandla e-peel, okungaguquki kwe-dielectric kanye nokukhubazeka okubukwayo.
Amaphuzu Okulawula Inqubo Eyinhloko
Amapharamitha abalulekile alawula ikhwalithi yomkhiqizo oqediwe yilena: ukukhishwa kwe-dewaxing okuphelele, ukumanzisa i-emulsion egcwele, ukomisa izinga lokushisa eliphansi kancane kancane, ukulungiselelwa okunembile kwezinga lokushisa le-sintering, kanye nokuminyana kokunamathela okungaguquki ngemva kwemijikelezo eminingi yokufaka.
