I-Jiangsu Aokai New Materials, umenzi oqeqeshiweyo we-PTFE yelaphu lobushushu obuphezulu, unikezela ngentshayelelo epheleleyo. Inkqubo yokufakwa kwelaphu le-fiberglass kunye ne-PTFE dispersion yeyona teknoloji ingundoqo yokugqoka kunye ne-sinter polytetrafluoroethylene kwi-fiberglass substrate, ukwenza izinto ezidibeneyo ezinokumelana nobushushu obuphezulu, ukugquma kombane kunye nokusebenza okungaguqukiyo. Iimveliso ezinjalo zisetyenziswa ngokubanzi kwi-laminates ye-copper-clad high-frequency, i-high-temperature non-stick conveyor belts, izixhobo ze-membrane zokwakha kunye nezinye iindawo.
Inkqubo epheleleyo esisiseko inamanyathelo asixhenxe angundoqo ngolu hlobo lulandelayo:
1. I-Fiberglass Fabric Fabric Pretreatment (I-Dewaxing / Desizing)
Eli lelona nyathelo libalulekileyo lonyango lwangaphambili. Isixhobo sokulinganisa i-agent ye-textile (ingakumbi i-wax yeparafini, i-starch derivatives) iqatywe kwiifilaments ze-fiberglass ngexesha lokuluka; Ukususwa okungaphelelanga kuya kuphazamisa kakhulu i-interfacial bonding phakathi kwe-PTFE kunye nemicu yeglasi.
· Indlela yonyango ephambili: Ilaphu lidlula ngokuqhubekayo kwiziko lobushushu obuphezulu bobushushu obuphantsi kwe-thermal dewaxing kwi-350 ~ 400 ° C, i-oxidizing ngokupheleleyo kunye nokubola zonke ii-agent ze-organic sizing.
• Ukuphathwa okulandelelweyo: Ilaphu elinyibilikisiweyo lipholiswa phantsi, ngamanye amaxesha lihlanjululwe ngamanzi acocekileyo okanye izinyibilikisi zekhemikhali ukuze kususwe uthuthu olushiyekileyo, lize lomiswe ukuze kufunyanwe ilaphu elimhlophe elingenanto elicocekileyo elilungele ukumiliselwa.
· Imathiriyeli ekrwada: Usasazo olugxininisiweyo lwe-PTFE olunomxholo osemgangathweni oqinileyo malunga nama-60%.
· Inkqubo yokuxuba: Nciphisa i-stock disspersion ngamanzi a-deionized kugxininiso ekujoliswe kulo (40% -55%) ngokusekelwe kwi-resin efunekayo yokulayishwa kunye ne-impregnation viscosity. I-surfactant efanelekileyo yongezwa ukunyusa ukusebenza kokumanzisa kwi-fiberglass; i-thickener inokudityaniswa ukulungisa i-viscosity xa kuyimfuneko.
3. Ukukhulelwa
Eyona nto iphambili ekujoliswe kuyo kukungena ngokupheleleyo kwe-PTFE emulsion kwi-fiber bundles kunye ne-interstices yelaphu elilukiweyo.
1. I-Dip-Csqueeze Method (Eyona nto yamkelwe ngokubanzi): Ilaphu likhokelwa ngokuntywiliselwa ngeerola ukuze zicwilise ngokupheleleyo kwitanki ye-emulsion, emva koko idlule ngepere yeerola zokucudisa. Ubunzima bokugquma bulawulwa ngokulungelelanisa uxinzelelo lwe-roller nip ukukhupha i-emulsion engaphezulu kunye nokusabalalisa i-resin ngokufanayo.
2. UGqirha Blade Coating: I-Emulsion isasazeke phezu komphezulu welaphu ngamacangci esinyithi, alungele ukusasazeka kwe-viscosity ephezulu.
4. Ukomisa
Ilaphu elimiliselweyo lingena kwi-oven yokomisa ubushushu obuphantsi obusebenza ku-100 ~ 150°C.
· Injongo: Phumeza amanzi ngobunono kunye nee-surfactants ezingaphelelanga, wenze ifilim eyomileyo nengeyo-tacky yamasuntswana e-PTFE kumphezulu wefiber.
· Inqaku lolawulo lobushushu: Ubushushu obugqithisileyo buza kwenza ifilim yomhlaba exineneyo ngokukhawuleza, ibambe ukufuma kwangaphakathi okutshekayo ukwenza imingxunya kunye namadyungudyungu.
5. Sintering (Thermal Curing)
Ilaphu elomileyo lifakwe ngokukhawuleza kwi-furnace ye-sintering yokushisa ukushisa kwi-360 ~ 390 ° C (ukuya kwi-400 ° C kwamanye amabanga).
· I-Mechanism: I-PTFE yipolymer ye-thermoplastic. Kwiqondo lokushisa elikude ngaphezu kwendawo yokunyibilika kwayo (327 ° C), iinqununu ze-PTFE ziyanyibilika, zigeleze kwaye ziphume kwinqanaba ukuze zenze ifilimu eqhubekayo, ukufezekisa ukudibanisa komatshini kunye nokunamathela kunye neendawo ze-fiberglass.
· Ulwahlulo lwenqanaba: Indawo yokuntywila yohlulwe ngokwendawo yokufudumeza, iqondo lobushushu elingaguqukiyo kunye namacandelo okupholisa ukuqinisekisa ukudityaniswa okupheleleyo kwamasuntswana ngaphandle kokuthotywa kobushushu.
6. I-Multi-Cycle Impregnation & Sintering
Umjikelo we-impregnation-sintering enye uvelisa kuphela i-ultra-thin coating ethanda ukuba neziphene zepinhole. Ukufikelela kwithagethi yokugquma ukuqina kunye nomxholo we-resin (umzekelo, i-45% -65% yokulayishwa kwe-resin kwi-high-frequency copper-clad laminate substrates), ulandelelwano olupheleleyo lokukhulelwa → ukomisa → i-sintering iphinda iphindwe kabini ukuya kwii-4 amaxesha okanye ngaphezulu. Umjikelo ngamnye uzalise ngakumbi izithuba zefiber kwaye unyuse ubukhulu bokugquma, ekugqibeleni wenze icwecwe elishinyeneyo elishinyeneyo elingenamibhobho.
7. Emva koNyango & Ukugquma
1. Ukuguqulwa komphezulu: Emva kokupasa kokugqibela kwe-sintering, unyango lwe-corona okanye ikhemikhali ye-sodium-naphthalene etching ingasetyenziselwa ukuphucula ukunamathela komphezulu ngaphandle kokonakalisa i-substrate, iququzelele i-copper cladding elandelayo okanye i-coating yesibini.
2. I-Edge yokucheba kunye nokujika: Imiphetho yelaphu iyasikwa ngokuthe tye, emva koko ilaphu eligqityiweyo lihlatywe kakuhle ngumatshini wokuthatha.
3. Ukuhlolwa komgangatho: Uvavanyo olugcweleyo lweemveliso ezigqityiweyo kubandakanya ubunzima obusisiseko, ubukhulu, amandla okuqina, amandla e-peel, i-dielectric engaguqukiyo kunye neziphene ezibonakalayo.
Amanqaku oLawulo lweNkqubo engundoqo
Iiparamitha ezibalulekileyo ezilawula umgangatho wemveliso ogqityiweyo zezi: ukukhupha ngokupheleleyo / ukukhupha, ukumanzisa i-emulsion epheleleyo, ukomisa ubushushu obuphantsi kancinci kancinci, ukusetwa kweqondo lobushushu elichanekileyo, kunye nokuxinana kokutyabeka emva kwemijikelo emininzi yokufakwa.
Lo mxholo wobugcisa ungentla unikwe ngu I-Jiangsu Aokai yeZixhobo eziNtsha zeTekhnoloji Co., Ltd.
