PTFE Xabagta Xabagta ?
Sidee buu qaab-dhismeedka microporous u qaabayn karaa sharooto heerkul-sare ah oo Teflon ah oo la neefsan karo oo dheellitiri kara dahaadhka iyo guryaha aan dhegta lahayn
Sidee bay u nakhshadaysaa qaab-dhismeedka microporous ee Teflon la neefsan karo ee sharooto heerkulkiisu sarreeyo dheellitirnaanta dabaysha iyo guryaha aan dhegta lahayn?
JiangsuTeflon-Heerkulka Sare-Saaraha Dharka-JiangsuAokaiNewMaterialTechnologyCo.,Ltd.waxa ay xasuusinaysaa in tani ay muhiimad gaar ah u leedahay in la kordhiyo isku dhafka dhismaha iyo korka/hantiyada waaweyn ee shaqeeya.
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 isku xira' taas oo sabab u ah sabirka. 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 hantida mid kale,balse isku-dubbarididdaporesize,porosity,poregradient,dhirrada,iyo korka-daawaynta 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, micropores aadka u liidata (submicr) onscale) si mug leh u kordhiso burburka tamarta
Waxqabad la'aanta: Marka ay aad u yaraato wax ka yar waxyaabaha muhiimka ah ee loo yaqaan 'molecular chainradiusofgyrationorthemeltviscosity of hot-meltadhesives(tusaale,PE,PP),mawduuca ma soo saari karo micropores-ka. edPTFEfibrilson dusha sare, taasoo keentay in aan aad u aadka u aadka u mallactualcontactarea, sothen-stickproperty ayaa weli ah waxyeello.
2.2ControlPorosityina Dhexdhexaad (50%-70%)
Toolowporosity (<30%) ma bixin karto wax-qabad la taaban karo; aad u sarreeya (> 80%) waxay hoos u dhigtaa maadada adag si xad dhaaf ah, taasoo sababta xumaanta sii xumaanaysa ee ku-tiirsanaanta 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 inuu maraa dariiqyada togan, kaas oo kordhiya burburka hawada si wax ku ool ah si uu u xakameeyo habka toosan - iyada oo la sii daayo kanaalada. Hightortuosity waxay soo saartaa ku-tiirsanaanta ku-tiirsanaanta wax-ku-oolka ah ee ka-soo-baxa ka-soo-baxa is-barbardhigga ilaa weakerone, oo u oggolaanaysa in yar-yar oo-soo-noqoto-baddelka beddelka isku-halaynta sare.
2.4DhismahaAsymmetricGradient-DenseSurface, Dense Dusha sare ee gudaha,Dhinaca gudaha ee cufnaanta lakabka sare (qararan1-5μm)
Iyada oo loo marayo xisaabinta kulaylka, heerkulka muddada-gaaban-dhexeeya, ama ku daboosha ultra-thinfluoropolymer-ka (tusaale, TeflonAF), xidhiidhka dusha sare ee shayga shaqada ee la helo muuqaal la mid ah filimaanta. The bulkretainsa aadka u bool-boossan lakabka Neefsashada: Hoos lakabka maqaarka, walxuhu wali waxay sii wadaan shaqada shabakad aad u sareysa oo ku xidhan micropores.
Saamaynta: Xakamaynta waxaa u badan lakabka, waxqabadka aan dhejiska lahayn waxaa lagu dammaanad qaaday galmoodka dheemanka hoose ee korka hoose ee gyandultra-finepores, iyo daciifnimada reliesoninterlayerdiffus ionandedgeconvection.Marka la isticmaalo mishiinada kuleyliyaha lagu xidho,dabada dusheeda kuma dhegganfilmka moleten,halka qoyaanka iyo isbedbedelaya waxa lagu eryi karaa iyada oo loo marayo softehemicroporouslayer.

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 dhismaha:
dahaarka iyo waxqabadka aan ku dhegganayn ayaa lagu bixiyaa korka-korka-denseskinorultra-finemicropores;
Xakamaynta hawada waxaa lagu maamulaa gudaha gudaha, 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-ku waxay isla mar ahaantaa u heli kartaa fayrasyada guga, dahaarka, iyo waxqabadka aan-dhejinta lahayn ee ku-meel-gaadhka ah ee tilmaamaha.
Had iyo jeer waxay kor u qaaddaa xirfadda falsafada adeegga ay waddo daacadnimada dalka, iyo ku dhiirranaanta inaad ku siiso hal-joojin iyo adeeg fiiro gaar ah leh!
