Incazelo emfushane

Ama-alumina asebenzayo aklanyelwe ngokukhethekile ukukhiqizwa kokusebenza okuphezulu kwe-refractories lapho ukupakishwa kwezinhlayiyana ezichaziwe, i-rheology nezici zokubeka ezingaguquki zibaluleke njengezinto ezibonakalayo eziphezulu zomkhiqizo wokugcina. Ama-alumina asebenzayo agaywa phansi ngokugcwele kuze kufike kumakristalu ayinhloko (okukodwa) ngezinqubo zokugaya ezisebenza kahle kakhulu. Isilinganiso sikasayizi wezinhlayiyana, i-D50, zama-alumina asebenzayo e-mono-modal, ngakho-ke acishe alingane nobubanzi bamakristalu awo awodwa. Inhlanganisela yama-alumina asebenzayo nezinye izakhi ze-matrix, njenge-tabular alumina 20μm noma i-spinel 20μm, ivumela ukulawulwa kokusabalalisa usayizi wezinhlayiyana ukuze kuzuzwe i-rheology yokubeka oyifunayo.

Izici Zomkhiqizo

Ama-alumina asebenzayo ukusuka ku-sub-micron kuya kusayizi wezinhlayiyana ezincane ezi-3. Ukusatshalaliswa kosayizi wezinhlayiya, kusukela ku-mono-modal ukuya ku-bi-modal kanye ne-multi-modal, kuvumela ukuguquguquka okugcwele ekwakhiweni kokuklama futhi kuhlinzeke ngokunethezeka kwama-alumina asebenzayo ahlanganiswe ngobunjiniyela.

I-alumina micro-powder esebenzayo, eyenziwe ngenqubo yokucwilisa ngokukhethekile, inqubo yokugaya kanye nokuhlukaniswa kosayizi wamandla amaningi, inokuhlanzeka okuphezulu, ukusabalalisa usayizi wezinhlayiya ezinhle kanye nomsebenzi omuhle kakhulu we-sintering, olungele ukusetshenziswa ekukhiqizeni ukusebenza okuphezulu kwe-refrac-tory material. , kanye nemikhiqizo ye-ceramics ye-electronic .I-alpha alumina micropowerd esebenzayo ingalawulwa kahle ekusabalaliseni usayizi wezinhlayiyana kububanzi be-submicron, okuholela ekubeni ibe nokuminyana okuhle kakhulu kokusanhlamvu okupakisha okuhle kwe-rheological nokusebenza okuzinzile kanye nomsebenzi omuhle we-sintering, odlala umdlalo oyingqayizivele. indima ku-refractory:
1. Ngokuthuthukisa ukuqoqwa kwezinhlayiyana ukunciphisa inani elingeziwe lamanzi
2. Ukumelana nokugqokwa namandla emishini kuthuthukiswa ngokwenza isigaba esiqinile se-ceramic bonding;
3. Ukusebenza kokushisa okuphezulu komkhiqizo kuthuthukiswa ngokufaka esikhundleni se-ultra-fine powder nge-refractoriness ephansi.

I-Alumina Ultrafine ephinde yasebenza Yeziphazamisi Ezisebenza Kakhulu

Ama-alumina micro-powder asebenzayo angasetshenziswa kuma-ladle castable, ama-BF trough castable, amapulagi okuhlanza, amabhulokhi ezihlalo, ama-aluminium self-flow castable, kanye namamiksi esibhamu futhi, akhiqizwa kubhekiselwa kumazinga e-Transnational Corporation. Lawa ma-powder anokungcola okuphansi, ukusatshalaliswa kosayizi wezinhlayiyana okunengqondo nokusebenza kabusha, anikeza ama-castable ukugeleza okuhle, i-dilatancy encane, isikhathi esifanele sokusebenza, isakhiwo esiminyene namandla amahle kakhulu, futhi
zithunyelwe e-Japan, USA, naseYurophu.

Ama-Alumina Asebenzayo Okusebenza Okuphezulu Kwe-Refractories

Ama-alumina asebenza ngokuphelele emhlabathini aklanyelwe ngokukhethekile ukukhiqizwa kwezinqamuleli zokusebenza okuphezulu, lapho ukupakishwa kwezinhlayiyana ezichaziwe, i-rheology nezici zokubeka ezingaguquki zibaluleke kakhulu njengezinto ezibonakalayo eziphezulu zomkhiqizo wokugcina.

Ukusebenza Komkhiqizo
Ukusatshalaliswa kosayizi wezinhlayiyana ocolekile olawulwa kakhulu kuze kufike kububanzi be-sub-micron kanye nokusebenza kwawo okuhle kakhulu kwe-sintering kunikeza ama-Reactive Aluminas imisebenzi eyingqayizivele ekwakhiweni kwe-refractory.

Okubaluleke kakhulu yilezi:
• Nciphisa ukuxuba amanzi e-monolithic refractories ngokusiza ukuthuthukisa ukupakishwa kwezinhlayiyana.
• Khulisa ukumelana nemihuzuko namandla emishini ngokwakhiwa kwamabhondi e-ceramic aqinile.
• Khulisa ukusebenza kwemishini kwezinga lokushisa eliphezulu ngokufaka esikhundleni sezinye izinto ezicwebezelayo ze-oflower refractoriness.

Ukupakisha:
I-25KG/isikhwama, i-1000kg/isikhwama noma okunye ukupakisha okuqondile ngokwezidingo zomsebenzisi.
