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

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

1.EnsibukoOkukontanaWakatiEkizimbe ekitono n’Eby’obugagga Obuyita mu mpewo kyetaagisa okuyunga obutuli obuggule, nga buyita mu mikutu egy’obuziba.

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

Airpermeabilityvs.ebintu ebitali bya muggo: Eky’obugagga ekitali kya muggo kisibuka mu kikula kyaPTFE eky’amaanyi amatono ennyo ag’okungulu (~18mN/m) n’okusereba ku ngulu.Micropores byongera ku bukaluba 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 kuyita kw'empewo n'okuziyiza kungulu okutonnya n'okuyingira.

2.CoreApproachtoBalancedDesign:SynergisticModulationofMesoscopicStructuralParameters Ekisumuluzo 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.

Fornon-stickperformance: Omulimu gw’okukola emirimu egy’enjawulo: Bwe kiba nti obutuli buba butono okusinga obunene bw’okuyingira obukulu obusalibwawo emisinde gy’olujegere lwa molekyu obw’enzirugavu oba obuzito bw’okusaanuuka obw’ebizigo ebisaanuuka eby’ebbugumu (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, ebituli by’okungulu ebitono okusinga 0.5μm bisobola bulungi okuziyiza okuyingira kw’ebintu ebisinga okusaanuuka.

2.2OkufugaPorosityinaEkigeroEkigero(50%–70%) .

Obuziba bw’ebikozesebwa(<30%)tebusobola kuwa buyita bwa mpewo bwa nkola;obunene ennyo(>80%) bukendeeza ku bikalu ebiyitiridde,ekireeta okwonooneka okw’amaanyi mu insulation ne mechanicalproperties. Ataporosity around60%,theairpermeability(Gurleyvalue)canbe controlledmuthin20–100s/100cc,ate nga firimu 0.13mm obuwanvu esobola okukuuma amaanyi g’amasannyalaze aga ≥2kV, nga etuukana n’ebyetaago by’okuziyiza empewo.

Okuyita mu kukola kalenda mu bbugumu, okuteekebwa mu bbugumu erya waggulu ery’ekiseera ekitono, oba okusiiga n’ekirungo kya fluoropolymer ekigonvu ennyo (okugeza, TeflonAF), enjuyi ezikwatagana n’ekintu ekikola zifuna engulu 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 olussa olw’obutuli obunene: Wansi w’olususu, ebintu bikyakuuma omukutu omunene ogw’obutuli obw’obuwuka obutonotono obuyungiddwa.Gaasi esobola okutambuza 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 aga wansi ennyo ku ngulu nga n’obutundu obutono ennyo, n’okuyita kw’empewo kwesigama mu layeri ezisaasaana wakati ionandedgeconvection.Bwe bakozesa ebyuma ebisiba ebbugumu, engulu tepu tenywerera ku firimu esaanuuse, ate ng’obunnyogovu n’ebiwunya bisobola okugobwa okuyita mu mbiriizi z’ekiwujjo ekitono.

Obujjanjabi buno buteeka kungulu ne'micro/nanodual-phobicity,'okulongoosa eby'obugagga ebitali bya muggo okutuuka ku anti-obucaafu, nga kumpi tewali kufiirwa 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 bugabanya eby’obugagga bisatu mu mitendera gy’enzimba egy’enjawulo:

Enkola y’okuziyiza (insulation) n’etali ya muggo (insulation and non -stickperformance) eweebwa ebinene ebiriraanye n’okungulu 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 mu kiseera kye kimu okutuuka ku nkola ennungi ey’okuyita mu mpewo, okuziyiza, n’obutali muggo mu ngeri yonna.
