Sidee buu qaab-dhismeedka microporous u qaabayn karaa ee Teflon la neefsan karo cajalad heerkulkiisu sarreeyo dheellitirnaanta daalacashada hawada la dahaarka iyo guryaha non-dheg?
JiangsuTeflon-Heerkulka Sare-Saaraha Dharka-JiangsuAokaiNewMaterialTechnologyCo.,Ltd.waxa ay xasuusinaysaa in tani ay muhiimad gaar ah u leedahay xoojinta is-dhexgalka inta u dhaxaysa qaab-dhismeedka iyo korka/hababka hawl-fulinta badan.
Airpermeabilityvs.non-sticmaalka hantida: Hantida aan ku dhegganayn waxay ka soo jeedaan PTFE tamar aad u hooseeya (~ 18mN/m) iyo wejiga siman. etratethemicropores, samaynta 'farsamo is-dhexgal' taas oo sabab u ah sahayda. Sidaa darteed, maaddadu waxay si isku mar ah u gaari kartaa heerka hawada iyo kor u kaca iska caabinta qoynta iyo dhexgalka.
2.Core ApproachtoBalancedDesign:SynergisticModulation of MesoscopicStructuralParameters The keytobalance is not sadaqidda hanti mid kale,balse isku-dubarid poresize,porosity,poregradient, tortuosity,iyo korka daaweynta si loo qanciyo dhammaan si joogto ah oo joogto ah.
2.1Xakamaynta Celceliska Dhexroorka Cirifka (0.1-2μm) iyo Cabbirka Dhiirrigelinta Qaybinta Cidhiidhiga: Marka ay aad u yaraato oo ay ka yaraato elektarooniga waxay ka dhigan tahay dariiqa xorta ah iyo bilaabista waxay ka dhigaysaa qulqulka qayb ahaan, burburka hawadu waxay ku socotaa sharciga Baasaska; si kastaba ha ahaatee, fayrasyada aadka u sarreeya (submicr) onscale) si mug leh u kordhiso burburka tamarta
Waxqabad la'aanta: Marka ay aad u yaraato wax ka yar waxyaabaha muhiimka ah ee dhex galka ah waxaa lagu go'aamiyay molecularchainradiusofgyrationorthemeltviscosity of hot-meltadhesives(tusaale,PE,PP),mawduuca ma soo saari karo micropores. edPTFEfibrilson dusha sare, taas oo keentay in aan aad u aadka u-mallactualcontactarea, sothen-stickproperty-ku hadhsan yihiin sunnadu.
2.2ControlPorosityina Dhexdhexaad (50%-70%)
Toolowporosity(<30%) ma bixin karto wax-qabad la taaban karo; aad u sarreeya (> 80%) waxay hoos u dhigtaa mawduuca xad dhaafka ah, taasoo sababta xumaanta sii xumaanaysa ee ka-hortagga iyo hantida farsamada. Ataporosity agagaarka 60%, heerkulbeegga hawada (Gurleyvalue) waxaa lagu xakameyn karaa gudaha 20-100s/100cc, halka filim0.13mm dhumucdiisuna ay sii wadi karto xoogga koronto ee≥2kV, kulanka inta badan shuruudaha kuleyl-sealing.
2.3AdoptaHigh-Tortuosity3DNetworkPoreStructure
The ' node-fibril' qaab dhismeedka PTFE si dabiici ah u qaabeeya sare tortuosity (τ≈2.54) .Gaasku waa in ay maraan waddooyin maran, taas oo kordhinaysa burburka hawada marinnada si wax ku ool ah u xakameeyo qaabaynta toosan-iyada oo la sii daayo channels. Hightortuosity waxay soo saartaa ku-tiirsanaanta ku-tiirsanaanta wax-ku-oolnimada ka-soo-baxa ka-soo-baxa is-barbardhigga ilaa weakerone, oo u oggolaanaysa in yar-yar oo-soo-noqoto-baddelka beddelka ku-tiirsanaanta sare.
2.4DhismahaAsymmetricGradient-DenseSurface-Dense Dusha sare, Dense Dusha sare ee gudaha oo ka liidata
Iyada oo loo marayo xisaabinta kulaylka, heerkulka muddada-gaaban-dhexeeya, ama ku daboosha ultra-thinfluoropolymer (tusaale, TeflonAF), xidhiidhka dusha sare ee shayga shaqada ee la helo muuqaal similartoadensefilim ah. The bulkretain si aad u boodo leh lakabka Neefsashada: Hoos lakabka maqaarka, walxuhu wali waxay sii wadaan shaqada shabakad aad u sareysa oo ku xiran micropores.
Saamaynta: Xakamaynta waxaa ka sarreeya lakabka dheesha, waxqabadka aan ku dhegganayn waxa lagu dammaanad qaaday dheeshu aadka u hooseeysa ee dusha sare ee fayraska gyandultra-finepores, iyo wax-soo-saarka reliesoninterlayerdiffus ionandedgeconvection.Marka la isticmaalo mishiinada kuleyliyaha lagu xidho,dabacadaha dusha kuma dhejina filimaanta,halka qoyaanka iyo isbeddellada lagu eryi karo iyada oo loo marayo qalabka softheerhemicroporouslayer.

Byplasmagraftingoffluorinatedmonomersorvapordepositionofanextremelythin(<50nm) lakabka dareeraha leh, oo lagu dahaadhayso dabaqa hoose ee dabaqa saaraha ayaa laga samayn karaa gudaha gidaarka softhemicropores.Tani waxay ka hortagtaa walxo-qoyan oo qoyan iyada oo aan la xidhin kanaalada. Daawayntani waxay ku siinaysaa wejiga 'yaro/nanodual-naceyb,' cusboonaysiinta hantida aan ku dhegganayn carrada-iska-hortagga ah, oo leh ugu yaraan masiibo.

4.Gabagabadii
Dheellitirka qaab-dhismeedka microporous-ka ee lagu neefsan karoTeflon-heerkulka sare ayaa si dhab ah loogu guuleystey injineernimada morphological , qaybinta hantida saddex-lahaan ee heerarka kala duwan ee qaabdhismeedka:
dahaarka iyo waxqabadka aan-ku dhegga lahayn ayaa lagu bixiyaa korka-korka-denseskinorultra-finemicropores;
Heerkulka hawada waxaa lagu maamulaa iyada oo gudaha ku xiran, shabakad makroporous ah oo dhib badan. Marka la eego muuqaalka korka ayaa la xakameynayaa qayb-hoosaadka-micrones-ka ah, gudaha gudaha iyo qulqulka si sax ah ayaa loogu daray qaab-dhismeedka radient, tape waxay isla mar ahaantaa u heli kartaa xayndaabyada, dahaarka, iyo waxqabadka aan-dhejin ee ku-meel-gaadhka ah ee tilmaamaha.
Had iyo jeer waxay kor u qaaddaa xirfadda falsafada adeegga ay waddo daacadnimada waddaniga ah, iyo ku dhiirranaanta inaad ku siiso hal-joojin iyo adeeg feejignaan leh!
