Ensengeka y’ensengekera ya microporous ey’olutambi lwa Teflon olw’ebbugumu eringi eyinza etya okugerageranya okuyisa empewo n’eby’obugagga ebiziyiza n’obutakwata?

JiangsuTeflonOmukozi w’olugoye olw’ebbugumu eringi–JiangsuAokaiNewMaterialTechnologyCo.,Ltd.kijjukiza nti kino mu bukulu kibeera kya nkolagana wakati w’ekizimbe eky’obuziba n’eby’obugagga eby’okungulu/eby’emirimu mingi.

1.EnsibukoOkukontanaWakatiEkizimbe ekitono n’Eby’obugagga Okuyita kw’empewo kwetaaga okuyungibwa mu butuli obuggule, nga buyita mu mikutu egy’obuziba.

Insulation(amaanyi g’amasannyalaze) . reliesonthematerial'sdensity.Okuyingiza obuwuka obutonotono obwenkanankana n'okutabula empewo(nga amaanyi amatono ag'okumenya ennimiro ga ~3kV/mm)mu matrix ya PTFE, era obutuli obuggule buwa amakubo agayinza okufuluma ekitundu n'okulondoola ebikulu.

Airpermeabilityvs.ebintu ebitali bya muggo: Eky’obugagga ekitali kya muggo kisibuka mu kikula kyaPTFE eky’amasoboza amatono ennyo ku ngulu (~18mN/m) n’obuziba obuseeneekerevu.Micropores zongera ku bugumu bw’okungulu n’ekitundu ekikwatagana ekituufu;ebintu ebisaanuuse oba ebinyirira biyinza okuba etratethemicropores,forming'mechanicalinterlocking' thatinsteadcausesadhesion.N'olwekyo,ekintu kiteekwa okutuuka mu kiseera kye kimu okutuuka ku busobozi bw'empewo n'okuziyiza kungulu okutonnya n'okuyingira.

2.CoreApproachtoBalancedDesign:SynergisticModulationofMesoscopicStructuralParametersEkisumuluzo ky’okutebenkeza si kusaddaaka kintu kimu ku kirala, naye nga kikwataganya okutunula obunene bw’obuziba, obuziba, obuziba, obuzito, n’obujjanjabi obw’okungulu okumatiza ebyetaago byonna bisatu omulundi gumu.

2.1FugaDiameter y’obutuli obwa wakati(0.1–2μm)n’obunene bw’obutuli obufundaOkugabanya Forinsulation: Nga obutuli butono nnyo okusinga obusannyalazo kitegeeza ekkubo ery’eddembemu nga n’okutandikawo kuzitowa olw’okufulumya ekitundu, okumenya mu bbanga ly’empewo kukyagoberera etteeka lya Paschen;naye, obuwuka obutonotono obutono ennyo (submicr onscale)cansignificantlyincreasethebreakdownvoltage.Okunoonyereza kulaga nti nga average poredimeeri skept wansi wa0.5μm, DCokumenya amaanyi aga 50-μm-obuwanvu PTFEfilm ekyasobola okutuuka waggulu wa 40kV/mm.

Ku mutindo ogutali gwa muggo: Bwe kiba nti obutuli buba butono okusinga obunene bw’okuyingira obukulu obusalibwawo emisinde gy’olujegere lwa molekyo egy’okuzimbulukuka oba obuzito bw’okusaanuuka obw’ebizigo ebisaanuuka ebibuguma (okugeza, PE,PP), okusaanuuka tekusobola kusengejja obuwuka obutonotono.Bwe bikwatagana edPTFEfibril ku ngulu, ekivaamu mu kitundu ekitono ennyo ekikwatagana mu makka, n’olwekyo eby’obugagga ebitali bya muggo bisigala nga tebikosebwa.Okutwalira awamu, ebitundu by’okungulu ebitono okusinga 0.5μm bisobola bulungi okuziyiza okuyingira kw’ebiziyiza ebisinga obungi eby’okusaanuuka.

2.2OkufugaPorosityinaEkigeroEkigero(50%–70%) .

Obuziba bw’ebikozesebwa(<30%)tebusobola kuwa buyita bwa mpewo bwa nkola;obunene ennyo(>80%) bukendeeza ku bikalu ebisusse, ekireeta okwonooneka okw’amaanyi mu insulation n’eby’ebyuma. Ataporosity around60%,theairpermeability(Gurleyvalue)canbe controlledwithin20–100s/100cc,ate nga firimu 0.13mm obuwanvu esobola okukuuma amaanyi g’amasannyalaze aga ≥2kV, nga etuukana n’ebyetaago by’okusiba empewo.

Hightortuosityera ekendeeza ku kwesigama ku buziba obw’obwenkanya ku buziba okuva mu nkolagana ya square okutuuka ku kerone enafu, kisobozesa obutuli obunene katono okukozesebwa mu kuwaanyisiganya olw’okwesigamizibwa kw’obuziba obusingako.

Okuyita mu kukola kalenda y’ebbugumu, okuteekebwa mu bbugumu erya waggulu ery’ekiseera ekitono, oba okusiiga n’ekirungo kya fluoropolymer ekigonvu ennyo (okugeza, TeflonAF), enjuyi ezikwatagana n’ekintu ekikola zifuna enjuba ezifaananako ne firimu enzito.Obuziba obutonotono buggalwa wansi ku minzaani ya nanometer oba okusaanuuka ekitundu n’okusibirwa, okutuuka ku mutindo ogutali gwa stick n’okulinnyisa okufuuwa. Ebinene bibeera n’oluwuzi lw’olususu olulina obutuli obunene: Wansi w’olususu, ebintu bikyakuuma omukutu omunene ogw’obutuli obw’obuwuka obutonotono obuyungiddwa.Gaasi esobola okutambuzibwa mu mabbali n’obuwanvu okuyita mu mbiriizi oba okuyita mu butuli obusigaddewo obw’obunene bwa nano mu lususu, nga bukuuma obutambuzi obusukka mu buziba.

Ebivaamu: Insulation efugibwa layeri enzito, omulimu ogutali gwa muggo gukakasibwa amasoboza g’olutimbe oluwanvu ennyo ku ngulu n’obutundu obutono obutono, n’okuyita kw’empewo kwesigama mu layeri ezisaasaana wakati ionandedgeconvection.Bwe bakozesa mu byuma ebisiba ebbugumu, engulu tepu tenywerera ku firimu esaanuuse, ate ng’obunnyogovu n’ebiwunya bisobola okugobwa okuyita mu mbiriizi z’ekiwujjo ekitono.

2.5Okujjanjaba ku nguluOluvannyuma lw’Okujjanjaba:Super-Oleophobic/HydrophobicModificationAwatali PoreBlockage Nga tuyita mu kusimbuliza pulasima okuva ku monomera emu oba omukka ogw’okuteekebwa mu layeri egonvu ennyo (<50nm) eya perfluorinated, okusiiga n’amasoboza ag’okungulu aga wansi kiyinza okukolebwa mu bbugwe ow’omunda mu bitundu by’obuwuka obutonotono.Kino kiziyiza okuteekebwa kw’ebintu ebikwatagana nga tebizibidde mikutu gya butuli. Obujjanjabi buno buba n'okungulu nga'micro/nanodual-phobicity,'okulongoosa eby'obugagga ebitali bya muggo okutuuka ku anti-obucaafu, nga kumpi tebufiiriddwa kuyita mu mpewo.

Okutwala ekitambi kyaPTFE ekissa omukka (obuwanvu bwa mm 0.13) ekikoleddwa mu ngeri esinga obulungi ng’ekyokulabirako:

4.Okumaliriza

Enzikiriziganya y’ensengekera y’obutuli obutonotono mu butambi obussa Teflon obw’ebbugumu erya waggulu bukulu butuukibwako okuyita mu yinginiya w’enkula , nga tugabanya eby’obugagga bisatu mu mitendera gy’enzimba egy’enjawulo:

Enkola y’okuziyiza n’etali ya muggo eweebwa ebinene ebiriraanye kungulu oba obuwuka obutono ennyo;

Okuyita kw’empewo kukwatibwako omukutu oguyungiddwa munda, ogw’obuziba obunene (tortuous macroporousnetwork). Nga obutuli bw’okungulu bwe bufugibwa mu kitundu ekitono, obutuli obw’omunda n’obuziba bwe bugattibwa bulungi n’ensengekera y’okusereba, tape esobola omulundi gumu okutuuka ku nkola ennungi ey’okuyita mu mpewo, okuziyiza, n’obutali muggo mu ngeri yonna.
