I-JiangsuTeflonHigh-TemperatureClothManufacturer–JiangsuAokaiNewMaterialTechnologyCo.,Ltd.ikhumbuza ukuba le nto ibalulekilematterofsynergy phakathi kwesakhiwo esineporousandsurface/bulkfunctionalproperties.
1.Imithombo yongquzulwanoPhakathi koLwakhiwo oluNcinci kunye neePropathi Ukungenwa komoya kufuna ukuqhagamshelwa kwimingxuma evulekileyo, kunye negesi edlula kwiitshaneli eziyingozi.
I-Insulation(dielectricstrength) reliesonthematerial'sdensity.Ukwazisa imicroporesisequivalenttomixingair(ngethalowbreakdownfieldfieldstrengthof~3kV/mm)kwiPTFEmatrix,kwayeipores zibonelela ngeendlela ezinokwenzeka zokukhupha ngokuyinxenye kunye nokulandela umkhondo wephepha.
Airpermeabilityvs.non-stickproperty: Ipropathi engeyiyo intonga isuka kwi-PTFE'se-extremely lowsurfaceenergy(~18mN/m)kunye nomphezulu ogudileyo.I-Microporesis yandisa ubungako bobunzima kunye ne-realcontactarea;imoltenmaterialsorviscousmediamaypen i-etratethemicropores, ukwenza'ukutshixana ngoomatshini'ekuthi endaweni kubangele ukuncamathelisa.Ngoko ke,itheatriya kufuneka ngaxeshanye ifezekise ukungenwa komoya kunye nokuxhathisa umphezulu ukumanzi nokungena.
2.INdlela engundoqo yokuYilwa okuLingeneyo:UModelo lweSynergisticStructural Parameters Isitshixo ulungelelwaniso aluchazisi enye ipropathi kwenye, kodwa ngolungelelwano ukuhambisa ubungakanani, iporosity, iporegradient, ubuxhwanguxhwangu, kunye nokuphathwa kobuso ukuze kwaneliswe zonke ezi mfuno ngaxeshanye.
2.1LawulauMndilili wePoreDiameter(0.1–2μm) kunye nePoreSize Distribution Insulation: Xa i-poresize incinci kune-electronithetha indlela ekhululekileyo kwaye ukuqaliswa ubungakanani bokukhupha inxalenye, ukutshatyalaliswa emoyeni kwisithuba somoya kusalandela umthetho wePaschen; nangona kunjalo, iimicropores ezintle kakhulu(submicr ngokomlinganiselo) umlinganiselo wokuqhawuka kwamandla. Uphononongo lubonisa ukuba xa umndilili weporediyamitha uhlala ungaphantsi kwe-0.5μm, ukophuka kweDCukomelela okofa50-μm-ukuqinaPTFEifilimu ingafikelela ngaphezu kwe-40kV/mm.
Fornon-stickperformance: Xa i-poresize incinci kunobungakanani bokungena okubalulekileyo kugqitywe yi-molecularchain radiusofgyrationorthemeltviscosityofhot-meltadhesives(umzekelo,PE,PP),ithemelt ayinakuhluza kwimicropores. I-edPTFE i-fibrilsomphezulu,isiphumo singenanxane-nxane incinci kakhulu,iproperty ye-sothenon-stick ihlala ingachaphazelekanga.Ngokubanzi,iporesssssmaller than0.5μmnokuthintela ukungenangobuninzi be-meltadhesives.
2.2UlawuloPorositiyinaUluhlu oluPhakathi (50%–70%)
Ukutshona kwee-olowporosity(<30%)akunakubonelela ngokusebenza komoya ukutshoneleka;iphezulu kakhulu(>80%)yicutha umanyano oluluqilima ngokugqithileyo,kubangela ukuwohloka okubukhalikukhuseleko kunye neepropathi zoomatshini. I-Ataporosityaround60%,i-airpermeability(Gurleyvalue) inokulawulwa ngaphakathi kwe-20–100s/100cc,ngelixa ifilm0.13mmthickcanmaintainadielectricstrengthof≥2kV,idibana ne-mostheat-sealinginsulationrequirements.
2.3AdoptaHigh-Tortuosity3DNetworkPoreStructure(asused byJiangsuTeflonHigh-TemperatureClothManufacturer)
I'i-node-fibril'ulwakhiwoofePTFE ngokwendalo lwenza ukuqina kwe-hightortuosity(τ≈2.54).Igesi kufuneka idlule kwiindledlana eziyingozi,eyonde kokuqhekeka umoyapathandeicinezela ngokufanelekileyoulwakhiwo oluthe ngqo-lokukhupha imijelo. I-Hightortuosityayayeyehlisa ukuxhomekekakokungaphelelwa komoya kwiporesizekulwalamano lwesikweri ukuya kwi-weakerone,ivumela iporestobe isebenzisekancinciinguqukokuthembela okuphezulu.
2.4I-ConstructanAsymmetricGradientPoreStructure-DenseSurface,I-PorousInterior Densesurfaceskinlayer(ukutyeba1–5μm)
Ngokuhamba kobushushu, ixesha elifutshane-ubushushu obuphezulu, okanye ukugquma nge-anultra-thinfluoropolymer(umzekelo, iTeflonAF), uqhagamshelwano nomphezulu wento esebenzayo ifuna ubuso obufana nefilim. Ubuninzi bugcina isaleko esiphefumla kakhulu: Ngaphantsi kwesiqwenga solusu,izinto eziphathekayo zigcina inethiwekhi edityanisiweyo yemicropores.
Isiphumo: I-Insulation ilawulwa yi-denselayer, umsebenzi ongasebenziyo uqinisekiswa ngamandla obuso bomdensela uphantsi kakhulu kunye ne-ultra-finepores, i-andairpermeabilityreliesoninterlayerdiffus ionandedgeconvection.Xa isetyenziswa koomatshini bokutywina obubushushu, ubuso betape ayincangathi kwifilimu enyibilikisiweyo, ngelixa ubumanzi kunye nokuguquguqukayo kunokukhutshwa ngaphaya kwemida yesaleko semicroporous.
2.5I-SurfacePost-Treatment:Super-Oleophobic/HydrophobicModificationNgaphandle kwePoreBlockage I-byplasmagraftingoffluorinatedmonomersordepositionofanextremelythin(<50nm)perfluorinatedlayer,ayamekwenomgangatho ongaphantsiubuso obungamandla angemikwinto yangaphakathi yeemicropores. Olu nyango lujongeka phezulu'nge-micro/nanodual-phobicity,'uphuculo lwepropertytoanti-soiling engeyiyo intonga, ephantse yakwazi ukudlula.
