I-Calcium Alumina Cement

I-Calcium Alumina Cement: Umenzeli Onamandla Ohlanganisayo Wezidingo Zakho Zezimboni

Uma kukhulunywa ngezinto zikasimende,I-Calcium Alumina Cement(CAC) igqama njengenketho ethembekile nephumelelayo.Yenziwe ngenhlanganisela ye-bauxite, i-limestone, ne-calcined clinker ene-calcium aluminate njengengxenye eyinhloko, le nto kasimende esebenza nge-hydraulic inika amandla amangalisayo nokuguquguquka.Okuqukethwe kwayo kwe-alumina engaba ngu-50% kuyinikeza izakhiwo ezibophezelayo ezingavamile, okuyenza ibe ukukhetha okudingekile ezimbonini ezihlukahlukene.

Isingeniso esifushane:

I-CAC, eyaziwa nangokuthi usimende we-aluminate, itholakala ngemibala ehlukene, kusukela kokuphuzi nokunsundu kuya kokumpunga.Lokhu kuhlukahluka kombala kuvumela ukuguquguquka ekusetshenzisweni kwayo, njengoba ingakwazi ukuhlangana ngaphandle komthungo nezinto ezihlukene kanye nezindawo.Noma ngabe usebenza embonini ye-metallurgy, petrochemical, noma usimende,I-Calcium Alumina Cementikhombisa ukuthi iyi-ejenti yokubopha efanelekile.

Inzuzo:

Enye yezinzuzo ezibalulekile zeCalcium Alumina Cement amandla ayo angavamile.Ukwakheka kwayo okuyingqayizivele kuqinisekisa inqubo yokwelapha esheshayo nephumelelayo, okukwenza ukwazi ukuthola imiphumela ehlala isikhathi eside ngesikhathi esifushane.Kungakhathaliseki ukuthi wakha izindawo zezimboni noma ulungisa izakhiwo ezikhona, izakhiwo ze-CAC ezinamandla zokuhlanganisa ziqinisekisa ukuxhumana okuhlala isikhathi eside nokuthembekile.

Ngaphezu kwamandla ayo, i-CAC iphinde ikwazi ukumelana namazinga okushisa aphezulu, okuyenza ifaneleke kakhulu ukusetshenziswa kuhhavini naseziko.Ikhono layo lokumelana nokushisa okukhulu liqinisekisa ukuthi amaphrojekthi akho okwakha noma okulungisa ahlala eqinile ngisho nasezimweni ezinzima kakhulu.Lesi sici sizuzisa kakhulu ezimbonini lapho ukuzinza kwe-thermal kubalulekile ekusebenzeni kahle nokuphepha.

Ngaphezu kwalokho, i-Calcium Alumina Cement inikeza ukumelana namakhemikhali okukhethekile, okuyenza ibe ukukhetha okuhle ezindaweni ezibandakanya ukuchayeka ezinto ezonakalisayo noma ama-agent anamandla.Ukwakheka kwayo okuqinile kuvimbela ukuwohloka okubangelwa ukusabela kwamakhemikhali, okuqinisekisa ubuqotho nokuphila isikhathi eside kokufaka kwakho.Lesi sici sibaluleke kakhulu ezimbonini lapho ukugcinwa kobuqotho besakhiwo sezinto zokusebenza nezinsiza kubaluleke kakhulu.

Uma kubhekwa isimo sokuncintisana semikhakha yezimboni, ukusebenza kahle kanye nokukhiqiza kubalulekile ukuze uphumelele.I-Calcium Alumina Cement inikeza inzuzo nalokhu.Izakhiwo zayo zokubeka ngokushesha kanye nokuthuthukiswa kwamandla angaphambi kwesikhathi kunciphisa kakhulu isikhathi sokwakha futhi kuthuthukise izikhathi zephrojekthi.Ngokusebenzisa i-CAC, ungonga isikhathi esibalulekile nezisetshenziswa kuyilapho uqinisekisa imiphumela yekhwalithi ephezulu.

Isici:

I-CalciumAlumina Cementsets ngokushesha.Amandla e-1d angafinyelela ngaphezu kwamaphesenti angu-80 wamandla aphezulu, ikakhulukazi asetshenziselwa amaphrojekthi aphuthumayo, njengokuvikela izwe, imigwaqo kanye namaphrojekthi okukhanda akhethekile.

Ukushisa kwe-hydration kweCalciumAlumina Cementis kukhulu kanye nokukhululwa kokushisa kugxilile.Ukushisa kwe-hydration okukhishwe ku-1d kungu-70% kuya ku-80% wengqikithi, ukuze izinga lokushisa langaphakathi likakhonkolo likhuphuke, ngisho noma ukwakhiwa ku--10 ° C, i-CalciumAlumina Cementcan ibeka ngokushesha futhi ibe lukhuni, futhi ingasetshenziswa ebusika. amaphrojekthi wokwakha.

Ngaphansi kwezimo ezijwayelekile zokuqina, i-CalciumAlumina Cementa ine-sulfate corrosion resistance eqinile ngoba ayinayo i-tricalcium aluminate ne-calcium hydroxide, futhi inokuminyana okuphezulu.

I-CalciumAlumina Cementa inokumelana nokushisa okuphezulu.Okufana nokusetshenziswa kwe-refractory coarse aggregate (njenge-chromite, njll.) kungenziwa ngokhonkolo ongamelana nokushisa ngezinga lokushisa elingu-1300 ~ 1400℃.

Kodwa-ke, amandla esikhathi eside kanye nezinye izakhiwo zeCalciumAlumina Cementabe nomkhuba wokunciphisa, amandla esikhathi eside ancishiswa cishe ngo-40% kuya ku-50%, ngakho-ke i-CalciumAlumina Cementis ayifaneleki izakhiwo ezithwala umthwalo wesikhathi eside namaphrojekthi izinga lokushisa eliphezulu kanye nemvelo yomswakama ophezulu, ifaneleka kuphela ubunjiniyela bezempi obuphuthumayo (imigwaqo yokwakha, amabhuloho), imisebenzi yokulungisa (ukuxhuma, njll.), amaphrojekthi wesikhashana, kanye nokulungiselela ukhonkolo ongamelana nokushisa.

Ngaphezu kwalokho, ukuxutshwa kweCalciumAlumina Cementnosimende wasePortland noma umcako akukhiqizi nje kuphela ukuqina kwe-flash, kodwa futhi kubangela ukuqhekeka kukakhonkolo ngisho nokucekela phansi ngenxa yokwakheka kwe-alkaline hydrated calcium aluminate.Ngakho-ke, ngaphezu kokuxuba nge-lime noma i-Portland usimende ngesikhathi sokwakhiwa, akufanele isetshenziswe ngokuthintana nosimende wasePortland ongaqinile.

Sengiphetha, i-Calcium Alumina Cement inikeza inhlanganisela yamandla, ukuguquguquka, nokuqina, okuyenza ibe inketho yokukhetha izidingo zokuhlanganisa imboni.Kungakhathaliseki ukuthi uhileleke ku-metallurgy, amakhemikhali e-petrochemical, noma ukukhiqizwa kukasimende, i-CAC iqinisekisa imiphumela engavamile.Izakhiwo zayo zokusheshisa, amandla okuqala aphezulu, nokumelana nezinga lokushisa eliphezulu namakhemikhali kuyenza ibe yimpahla ebalulekile kunoma iyiphi iphrojekthi.Khetha i-Calcium Alumina Cement ukuze uthole izixazululo ezinamandla nezithembekile zesibopho ezihlala isikhathi eside.
