I-JiangsuTeflonHigh-TemperatureClothManufacturer–JiangsuAokaiNewMaterialTechnologyCo.,Ltd.ikhumbuza ukuba le nto ibalulekilematterofsynergy phakathi kwesakhiwo esineporousandsurface/bulkfunctionalproperties.
1.Imithombo yongquzulwanoPhakathi koLwakhiwo oluNcinci kunye neePropathi Ukungenwa komoya kufuna ukudityaniswa kwemingxuma 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'esezantsi ngokugqithisileyo kumphezulu wamandla(~18mN/m) kunye nomphezulu ogudileyo.I-Microporesis yandisa ubungako bobunzima kunye neyona nto idibene nonxibelelwano;imoltenmaterialsorviscousmediamaypen i-etratethemicropores, ukwenza'ukutshixana ngoomatshini'ekuthi endaweni kubangele ukunamathela.Ngoko ke,itheatriya kufuneka ngaxeshanye ifezekise ukungenwa komoya kunye nokunganyangeki komphezulu ukumanzi nokungena.
2.Indlela engundoqo yoYilo oluLingeneyo:Uhlengahlengiso lweMesoscopicStructural Parameters Isitshixo ulungelelwaniso aluchazisiipropathi enye kwenye,kodwa ngolungelelwano ukuhambisa ubungakanani,iporosity,poregradient, tortuosity,kunye nokuphathwa komphezulu ukuze kwaneliswe zonke ezi mfuno ngaxeshanye.
2.1LawulauMndilili wePoreDiameter(0.1–2μm) kunye nePoreSize Distribution Insulation: Xa i-poresizeism incinci kune-electronithetha indlela ekhululekile kwaye ukuqaliswa ubungakanani bokukhupha inxalenye, ukuphuka emoyeni kwisithuba somoya kusalandela umthetho wePaschen; nangona kunjalo, iimicropores ezintle kakhulu(submicr ngokomlinganiselo) umlinganiselo wokuqhawuka ngamandla.Uphononongo lubonisa ukuba xa umndilili weporeemitha uhlala ungaphantsi kwe-0.5μm, ukophuka kweDCukomelela okofa50-μm-ukuqinaPTFEifilimu ingafikelela ngaphezu kwe-40kV/mm.
Fornon-stickperformance: Xa i-poresize incinci kune-criticalukungena ubungakanani kugqitywe yi-molecularchain radiusofgyrationorthemeltviscosityofhot-meltadhesives(umzekelo,PE,PP),ithemelt ayinakuhluza kwimicropores.Iyofowunelwa kuphela I-edPTFE i-fibrilsomphezulu, isiphumo singenanxane-nxane incinci kakhulu, iproperty ye-sothenon-stick ihlala ingachaphazelekanga. Ngokubanzi, umphezulu weporesssmaller than0.5μmnokuthintela ukungena ngobuninzi be-meltadhesives.
2.2LawulaPorositynaUluhlu oluPhakathi (50%–70%)
Ukutshona kwee-olowporosity(<30%)akunakubonelela ngokwenzekayo emoyeni;uphezulu kakhulu(>80%)ukwehlisaukholo oluqinileyo ngokugqithileyo,okubangela ukuwohloka okubukhalikukhuseleko kunye neepropathi zoomatshini. I-Ataporosityaround60%,i-airpermeability(Gurleyvalue) inokulawulwa ngaphakathi kwe-20–100s/100cc,ngelixa ifilm0.13mmthickcanmaintainadielectricstrengthof≥2kV,idibana neemfuno zokuqinisa umbane.
2.3AdoptaHigh-Tortuosity3DNetworkPoreStructure(asused byJiangsuTeflonHigh-TemperatureClothManufacturer)
I'i-node-fibril'ulwakhiwoofePTFE ngokwendalo lwenza ukuqina kwe-hightortuosity(τ≈2.54).I-Gasesmayidlule kwiindledlanaezinzima,eyongeza uqhekeko-moyaipathandeicinezela ngokufanelekileyoulwakhiwo lwemijelo ethe ngqo-yokukhupha. I-Hightortuosityakwayeyehlisa ukuxhomekekakokungaphelelwa komoya kwiporesizekulwalamano lwesikweri ukuya kwi-weakerone,ivumela iporestobeinkulu kancinane ukuba isetyenziselweinguqu ekuthembekeni 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 obufanayo nefilim. Ubuninzi bugcina isaleko esiphefumla kakhulu: Ngaphantsi kwesiqwenga solusu,izinto eziphathekayo zigcina inethiwekhi edityaniswe kakhulu 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 betapeayinamatheli kwifilimu enyibilikisiweyo,ngelixa ubumanzi kunye nezinto eziguquguqukayo zinokukhutshwa ngaphaya kwemida yesaleko semicroporous.

Olu nyango lujongeka phezulu'nge-micro/nanodual-phobicity,'uphuculo lwepropertytoanti-soiling engeyiyo intonga, ephantse yakwazi ukudlula.
