Imboni yephepha ihlala ifuna izindlela zokuthuthukisa ikhwalithi yephepha nokunciphisa izindleko zokukhiqiza. I-silicon dioxide (i-silicon dioxide/i-carbon black/i-silica) isibe yisithako esibalulekile ekwenzeni iphepha ngenxa yesakhiwo sayo esiyingqayizivele somzimba kanye nezakhiwo zamakhemikhali. Izinhlayiya zayo eziyindilinga ezincane, ezinendawo ethile evame ukwedlula ama-200 m²/g, zixhumana ezingeni lama-molecule nemicu yephepha, okwenza kube nokuthuthukiswa okunemisebenzi eminingi. Ingasetshenziswa njengesigcwalisi, i-pigment yokumboza, kanye ne-ejenti yosayizi enkambisweni yokwenza iphepha, ithuthukisa ngempumelelo amandla ephepha, ukushelela, kanye nokuphrinta. Kungakhathaliseki ukuthi yiphepha elimbozwe kahle kakhulu lokuphrinta noma iphepha elithambile lokusetshenziswa nsuku zonke, i-carbon black emhlophe ingadlala indima ebalulekile ekwenzeni ngcono ukusebenza komkhiqizo.

Ikhabhoni yethu emhlophe evuvukele ephepheni elimboziwe idlula enkambisweni ekhethekile yokwenziwa kwe-hydrothermal, iqinisekisa usayizi wezinhlayiya omaphakathi ongu-20-30nm. Lobu bunjiniyela bokunemba kunciphisa ukujiya kobuso bekhabhoni kube ngaphansi kuka-0.5μm, okwenza iphepha elimboziwe libe nobuso obubushelelezi obufana nesibuko. Ngesikhathi sokuphrinta, uyinki ungamuncwa ngokulinganayo, kugwenywe izinkinga ezifana nokufiphala kweyinki nombala ongalingani. Umkhiqizi wephepha lokuphrinta ohamba phambili eJapane wenze isivivinyo sezinyanga eziyisithupha, enezela u-10% womnyama wethu omhlophe wekhabhoni efomini yabo yokumboza iphepha elimboziwe. Imiphumela yayimangalisa: ukwanda okungu-25% kokukhazimula kwephepha, ukuthuthuka okungu-15% encazelweni yokuphrinta, kanye nokwanda okungu-20% esivinini sokomisa kwekhabhoni, okuthuthukisa kakhulu ukusebenza kahle kokukhiqiza. Ngaphezu kwalokho, ukumelana kwephepha ekukhuculukeni kukhuphuke ngo-18%, kwandisa isikhathi salo sokuphelelwa yisikhathi futhi kwathuthukisa ukuncintisana kwalo emakethe.

Kwiphepha lezicubu, ubumnene namandla kuyizinkomba ezimbili ezibalulekile abathengi abazikhathalelayo. Iphepha lezicubu lendabuko livame ukuba nenkinga yokungabi namandla—kulula ukuliphula uma limanzi. Ukwengeza inani elifanele lekhabhoni elimhlophe elimnyama ephepheni lezicubu kungaxazulula le nkinga. Indawo enkulu yobuso bekhabhoni elimhlophe elimnyama liyivumela ukuthi yakhe izibopho ze-hydrogen nezintambo ze-cellulose ephepheni, okwandisa amandla okubopha phakathi kwezintambo. Uma inani lokwengeza lingu-1-2%, amandla okuqina okomile ephepha lezicubu angandiswa ngo-10%, futhi amandla okuqina okumanzi angandiswa ngo-15%, kuyilapho ubumnene bephepha lezicubu bungathinteki. Lokhu kungenxa yokuthi izinhlayiya ezincane kakhulu zekhabhoni elimhlophe elimnyama zingagcwalisa izikhala phakathi kwezintambo ngaphandle kokwakha isakhiwo esiqinile, okuqinisekisa ukuthi iphepha lezicubu lihlala lithambile futhi likhululekile ukulisebenzisa.

Umkhiqizo wephepha lezicubu laseYurophu uhlanganise umbala wethu omnyama wekhabhoni emhlophe emgqeni wawo wokukhiqiza futhi wenza izivivinyo zabathengi ezingaboni. Imiphumela ibonise ukuthi abathengi abangu-82% bathanda umkhiqizo othuthukisiwe, becaphuna amandla awo athuthukisiwe kanye nobuthambile obungashintshi. Ngenxa yalokho, imikhiqizo yabo yathola udumo olukhulu kubathengi, futhi ukuthengiswa kwanda ngo-30% zingakapheli izinyanga eziyisithupha. Ukuhlaziywa okwengeziwe kwembule ukuthi ukwengezwa kombala omnyama wekhabhoni emhlophe nakho kuthuthukise ukumelana kwephepha ekuphuzeni, kugcina ubumhlophe balo isikhathi eside.

Ekukhiqizweni kwamaphepha akhethekile njengephepha lokuhlunga kanye nephepha lokufaka ugesi, izakhiwo ezihlukile ze-white carbon black nazo zisetshenziswa ngokugcwele. Iphepha lokuhlunga lokwelashwa kwamanzi kudingeka libe nezimbobo ezinhle kanye namandla okumunca. Ukwengeza i-silica efumile enosayizi wezinhlayiya ongu-5-10nm ephepheni lephepha lokuhlunga kungandisa izimbobo zephepha ngo-20%. Izinhlayiya ze-silica zinamandla amakhulu okumunca ukungcola okufana nama-ion ensimbi esindayo kanye nezinto eziphilayo emanzini, okwenza iphepha lokuhlunga libe nokusebenza kahle kokuhlunga okuphezulu, futhi ukunemba kokuhlunga kungafinyelela ku-0.1μm.

Kuphrojekthi yokuhlola enkampanini yokuhlanza amanzi, i-silica yethu evuthayo yasetshenziswa ekukhiqizweni kwephepha lokuhlunga. Imiphumela ibonise ukuthi izinga lokususwa kwama-ion ensimbi esindayo likhuphuke lisuka ku-75% laya ku-92%, kanti izinga lokususwa kwezinto ezingcolisayo eziphilayo likhuphuke ngo-25%. Ikhwalithi yamanzi ahlanziwe ihlangabezane nezindinganiso zamanzi okuphuza eziqinile zomhlaba wonke.

Iphepha lokuvikela ugesi lidinga amandla aphezulu e-dielectric kanye nokumelana nokushisa. Ukwengeza umnyama omhlophe wekhabhoni ocwebezelayo ohlanzekile kakhulu (okuqukethwe kwe-SiO₂ ≥99.9%) ku-pulp yephepha lokuvikela kungathuthukisa amandla e-dielectric ephepha kusuka ku-15kV/mm kuya ku-25kV/mm futhi kwandise izinga lokumelana nokushisa kusuka ku-Class A (105°C) kuya ku-Class B (130°C), okwenza lifaneleke ukusetshenziswa emishinini kagesi enamandla aphezulu.

Inkampani yethu ibambisene nomkhiqizi we-transformer ukuhlola ukusebenza kwephepha lokuvikela ngombala wethu omnyama wekhabhoni omhlophe. Ngemva kwamahora ayi-1000 okusebenza okuqhubekayo ku-120°C, iphepha lokuvikela ligcine ukusebenza okuhle kakhulu kokuvikela ngogesi, ngaphandle kokuwohloka okukhulu kwamandla e-dielectric. Lokhu kuphumelela kuvumele umenzi ukuthi athuthukise isizukulwane esisha sama-transformer asebenza kahle kakhulu, kunciphisa ukulahlekelwa kwamandla ngo-12%.

Inkampani yethu inikeza imikhiqizo ehlukahlukene ye-carbon black embonini yephepha, okuhlanganisa amamaki asakazeka kalula, ahlanzekile kakhulu, kanye namamaki amahle kakhulu. Amamaki ngalinye alungiselelwe izinqubo zokwenza iphepha—isibonelo, i-carbon black yethu emhlophe embozwe ngephepha inenani eliphansi lokumuncwa kwamafutha (≤150ml/100g), okunganciphisa inani le-binder elisetshenziswa embozweni, kwehlisa izindleko zokukhiqiza; i-carbon black yethu emhlophe embozwe ngephepha ine-water binder enhle, iqinisekisa ukusabalala ngokulinganayo epulp. Yonke imikhiqizo yethu ihlangabezana nezidingo zokuvikela imvelo zemboni yephepha, ngaphandle kwezinsimbi ezisindayo noma izinto eziyingozi, futhi ingabola endaweni yemvelo, kunciphisa ukungcola kwemvelo.

Ngokuphathelene nokuphathwa kwempahla, singahlinzeka ngokupakisha okuningi (500kg/isikhwama) kanye nokupakisha okuncane (25kg/isikhwama) ngokwezidingo zamakhasimende, futhi sibambisane nezinkampani zochwepheshe zokuphathwa kwempahla ukuqinisekisa ukuthi imikhiqizo ilethwa efektri yamakhasimende ngesikhathi esifanele nangendlela ephephile. Ithimba lethu lenkonzo yangemva kokuthengisa liyatholakala amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto ukubhekana nanoma yiziphi izinkinga ezihlobene nomkhiqizo, linikeze amakhasimende ulwazi olungenakukhathazeka.
