Calcium alumina usimende

Calcium alumina usimende: I-ejenti enamandla enamandla yezidingo zakho zezimboni

Uma kukhulunywa ngezinto zokwehla,Calcium alumina usimende(I-CAC) ivelele njengenketho ethembekile futhi esebenza kahle. Kwenziwe ngokuhlanganiswa kwe-bauxite, i-limestone, futhi ibanjiwe i-clinker nge-calcium ehambelana nengxenye eyinhloko, le ndaba ye-hydraulic cempting inikeza amandla amangalisayo kanye nokusebenza ngokuhlukahlukene. Okuqukethwe kwayo kwe-alumina okungama-50% kulinikeza izakhiwo ezibophayo ezihlukile, okwenza kube ukukhetha okusemqoka ezimbonini ezahlukahlukene.

Isingeniso Esifushane:

I-CAC, eyaziwa nangokuthi i-Aluminate Cement, iyatholakala ngemithunzi ehlukene, isukela kuphuzi nonsundu kuya ku-grey. Lokhu kuhlukahluka ngombala kuvumela ukuguquguquka ekusetshenzisweni kohlelo lwayo, ngoba kungahlangana ngomthungo ngezinto ezahlukahlukene kanye nezindawo ezihlukile. Noma ngabe usebenza nge-metallurgy, embonini ye-petrochemical, noma usimende embonini,Calcium alumina usimendekufakazela ukuthi yi-ejenti enobufakazi efanelekile.

Inzuzo:

Enye yezinzuzo ezisemqoka zeCalcium Alumina Cement ngamandla alo angavamile. Ukwakheka kwalo okuhlukile kuqinisekisa inqubo esheshayo nesebenzayo yelapha, okwenza ukuthi uzuze imiphumela eqinile ngesikhathi esifushane. Noma ngabe wakha izikhungo zezimboni noma ukulungisa izakhiwo ezikhona, izakhiwo ze-CAC ezinamandla ze-CAC ziqinisekisa ukuxhumana okuhlala njalo nokunokwethenjelwa.

Ngaphezu kwamandla ayo, i-CAC futhi iqhosha ngokumelana kahle namazinga okushisa aphezulu, okwenza kube lula kakhulu izinhlelo zokusebenza kuma-kilns nasemafeni. Amandla awo okumelana nokushisa okwedlulele okuqinisekisa ukuthi amaphrojekthi akho okwakha noma wokulungisa ahlala eqinile ngisho nasezinhlangeni ezinzima. Lesi sici sinenzuzo ikakhulukazi ezimbonini lapho ukuzinza okushisayo kubalulekile ekusebenzeni kahle nokuphepha.

Ngaphezu kwalokho, usimende we-calcium alumina unikeza ukumelana okuhlukile kwamakhemikhali, okwenza kube yindlela efanelekile yezindawo ezibandakanya ukuvezwa kwezinto ezilimazayo noma ama-ejenti anolaka. Ukwakheka kwaso okuqinile kuvimbela ukonakala okubangelwa ukusabela kwamakhemikhali, kuqinisekisa ubuqotho kanye nokuphila isikhathi eside kokufakwa kwakho. Lesi sici sibaluleke kakhulu ezimbonini lapho kugcinwa khona ubuqotho bemishini nezinsizakusebenza bubaluleke kakhulu.

Uma kucatshangelwa isimo sokuncintisana semikhakha yezimboni, ukusebenza kahle kanye nokukhiqiza kubalulekile ukuze uphumelele. UCalcium Alumina Cement unikeza inzuzo kulokhu. Izakhiwo zayo zokusetha okusheshayo kanye nokuthuthukiswa kwamandla okuphezulu okuphezulu kwehlisa kakhulu isikhathi sokwakha futhi kuthuthukise izikhathi ze-Project Project. Ngokusebenzisa i-CAC, ungagcina isikhathi esibalulekile nezinsizakusebenza ngenkathi uqinisekisa imiphumela ephezulu.

Ubuso:

Calcimalumina cements ngokushesha. Amandla we-1D angafinyelela ngaphezu kwama-80% wamandla aphezulu kakhulu, asetshenziselwa ikakhulukazi amaphrojekthi aphuthumayo, njengokuvikela izwe, imigwaqo kanye namaphrojekthi akhethekile wokulungisa.

Ukushisa kwe-hydration kweCalciusAlumina Cemende enkulu nokukhishwa kokushisa kugxiliwe. Ukushisa kwe-hydration kukhishwe ku-1D kungama-70% kuya ku-80% wenani eliphelele, ukuze izinga lokushisa langaphakathi likhuphuke likhuphuke, noma ngabe ukwakhiwa ku--10 ° C, kusetshenziswe kanzima, futhi kungasetjenziswa ebusika amaphrojekthi wokwakha.

Ngaphansi kwezimo ezijwayelekile zokuqina, iCalciusAlumina Cementhas eqinile yokuphikiswa kwesisulu se-sulfate ngoba ayiqukethe i-tricalcium aliccate kanye ne-calcium hydroxide, futhi inobukhulu obuphezulu.

Calcimalumina Cemementhas Ukuvikelwa Okuphezulu Okushisa. Okufana nokusetshenziswa kobumbano obukhali obuqili (njenge-chromite, njll.) Kungenziwa ngokhonkolo omelana nokushisa ngokushisa kuka-1300 ~ 1400 ℃.

Kodwa-ke, amandla esikhathi eside nezinye izakhiwo zeCalciusAlumina Cememethave umkhuba wokuncishiswa, amandla wesikhathi eside ancishiswa cishe ngama-40% kuya kwangama-50%, ngakho-ke iCalciusAlumina Cemendes ayilungele izinhlaka zemithwalo yesikhathi eside ku Ukushisa okuphezulu nendawo yomswakama ephezulu, kulungele kuphela ubunjiniyela bezempi abaphuthumayo (imigwaqo yokwakha, amabhuloho), imisebenzi yokulungisa (ukufakwa, njll.), amaphrojekthi wesikhashana, kanye nokulungiselela kokhonkolo ovimbela ukushisa.

Ngaphezu kwalokho, ukuxutshwa kweCalciusAlumina CememendWith Portland usimende noma i-lime akukhiqizi kuphela ukuqina kwe-flash, kepha futhi kubangela ukuthi ukhonkolo ukuqhekeka futhi sichithe ngisho ngenxa yokwakhiwa kwe-calcium egcwele kakhulu ye-alkaline hydrate ahambelana. Ngakho-ke, ngaphezu kokuxubana nosimende noma i-portland cement ngesikhathi sokwakha, akufanele kusetshenziswe ekuxhumaneni nomhlaseli ongahlangene nePorland Cement.

Ekuphetheni, usimende we-calcium alumina unikeza inhlanganisela yamandla, ukuguquguquka, kanye nokuqina, ukukwenza kube ukukhetha kwezidingo zezimboni zezimboni. Noma ngabe ubamba iqhaza ku-metallurgy, ama-petrochemicals, noma ukukhiqizwa kosimende, i-CAC iqinisekisa imiphumela ekhethekile. Izakhiwo zayo zokubeka ngokushesha, amandla aphezulu asekuqaleni, kanye nokumelana namazinga okushisa aphezulu namakhemikhali akwenza kube yimpahla ebalulekile kunoma yiliphi iphrojekthi. Khetha usimende we-Alumina we-Cilcium Alumina ngezixazululo ezinamandla ezinamandla nezinokwethenjelwa ezivezwa isikhathi.
