I-Calcium Alumina Cement

I-Calcium Alumina Cement: I-ejenti Enamandla Yokubopha Izidingo Zakho Zezimboni

Uma kukhulunywa ngezinto zokwakha usimende,I-Calcium Alumina Cement(CAC) ivelele njengenketho ethembekile nephumelelayo. Yenziwe ngengxube ye-bauxite, i-limestone, kanye ne-calcined clinker ene-calcium aluminate njengesakhi esiyinhloko, le nto yokufaka i-hydraulic cementing inikeza amandla amangalisayo kanye nokuguquguquka okuphawulekayo. Okuqukethwe kwayo kwe-alumina okungaba ngu-50% kuyinika izakhiwo zokubopha eziyingqayizivele, okwenza kube ukukhetha okubalulekile ezimbonini ezahlukahlukene.

Isingeniso esifushane：

I-CAC, eyaziwa nangokuthi i-aluminate cement, itholakala ngemibala ehlukene, kusukela kophuzi nonsundu kuya kompunga. Lokhu kuhlukahluka kombala kuvumela ukuguquguquka ekusetshenzisweni kwayo, njengoba ingahlangana kalula nezinto ezahlukene kanye nezindawo. Kungakhathaliseki ukuthi usebenza kuma-oven ensimbi, e-petrochemical, noma esimende embonini,I-Calcium Alumina Cementkufakazela ukuthi iyi-ejenti yokubopha efanelekile.

Inzuzo:

Enye yezinzuzo ezibalulekile ze-Calcium Alumina Cement amandla ayo angavamile. Ukwakheka kwayo okuyingqayizivele kuqinisekisa inqubo yokwelapha esheshayo nephumelelayo, okukuvumela ukuthi uthole imiphumela eqinile ngesikhathi esifushane. Kungakhathaliseki ukuthi wakha izikhungo zezimboni noma ulungisa izakhiwo ezikhona, izakhiwo ezinamandla zokubopha ze-CAC ziqinisekisa ukuxhumana okuhlala isikhathi eside nokwethembekile.

Ngaphezu kwamandla ayo, i-CAC iphinde ibe nokumelana okuhle kakhulu namazinga okushisa aphezulu, okwenza ifaneleke kakhulu ukusetshenziswa kuma-oven nama-oven. Amandla ayo okumelana nokushisa okukhulu aqinisekisa ukuthi amaphrojekthi akho okwakha noma okulungisa ahlala eqinile ngisho nasezimweni ezinzima kakhulu. Lesi sici siwusizo kakhulu ezimbonini lapho ukuzinza kokushisa kubalulekile ekusebenzeni kahle nasekuphepheni.

Ngaphezu kwalokho, i-Calcium Alumina Cement inikeza ukumelana kwamakhemikhali okumangalisayo, okwenza kube ukukhetha okuhle kakhulu ezindaweni ezihilela ukuchayeka ezintweni ezibolayo noma izinto ezinolaka. Ukwakheka kwayo okuqinile kuvimbela ukuwohloka okubangelwa ukusabela kwamakhemikhali, okuqinisekisa ubuqotho kanye nobude besikhathi sokufakwa kwakho. Lesi sici sibaluleke kakhulu ezimbonini lapho ukugcina ubuqotho besakhiwo semishini nezindawo kubaluleke kakhulu.

Uma ubheka indawo yokuncintisana yemikhakha yezimboni, ukusebenza kahle kanye nokukhiqiza kubalulekile empumelelweni. I-Calcium Alumina Cement inikeza inzuzo kulokhu futhi. Izakhiwo zayo ezisheshayo kanye nokuthuthukiswa kwamandla okuqala kunciphisa kakhulu isikhathi sokwakha futhi kuthuthukisa isikhathi sephrojekthi. Ngokusebenzisa i-CAC, ungonga isikhathi nezinsiza ezibalulekile ngenkathi uqinisekisa imiphumela esezingeni eliphezulu.

Isici：

Ama-Cementsets e-Calcium Alumina ngokushesha. Amandla e-1d angafinyelela ngaphezu kwama-80% wamandla aphezulu kakhulu, asetshenziswa kakhulu kumaphrojekthi aphuthumayo, njengokuvikela izwe, imigwaqo kanye namaphrojekthi okulungisa okukhethekile.

Ukushisa komswakama kweCalciumAlumina Cementi kukhulu futhi ukukhishwa kokushisa kugxilile. Ukushisa komswakama okukhishwa ku-1d kungu-70% kuya ku-80% wesamba, ukuze izinga lokushisa langaphakathi lekhonkrithi likhuphuke kakhulu, noma ngabe ukwakhiwa ku--10 ° C, iCalciumAlumina Cement ingaqina ngokushesha, futhi ingasetshenziswa kumaphrojekthi okwakha asebusika.

Ngaphansi kwezimo ezivamile zokuqina, i-CalciumAlumina Cement inokumelana nokugqwala kwe-sulfate okunamandla ngoba ayinayo i-triccalcium aluminate kanye ne-calcium hydroxide, futhi inobuningi obukhulu.

I-CalciumI-Alumina Cement inokumelana nokushisa okuphezulu. Njengokusetshenziswa kwe-aggregate eqinile engaphikisi (njenge-chromite, njll.) ingenziwa ngokhonkolo omelana nokushisa onezinga lokushisa elingu-1300 ~ 1400℃.

Kodwa-ke, amandla esikhathi eside kanye nezinye izakhiwo ze-CalciumAlumina Cement zinomkhuba wokuncipha, amandla esikhathi eside ancishiswa cishe ngo-40% kuya ku-50%, ngakho-ke i-CalciumAlumina Cementi ayifanele izakhiwo namaphrojekthi athwala umthwalo wesikhathi eside ezindaweni ezinokushisa okuphezulu kanye nomswakama ophezulu, ifanele kuphela ubunjiniyela bezempi obuphuthumayo (ukwakha imigwaqo, amabhuloho), imisebenzi yokulungisa (ukuxhuma, njll.), amaphrojekthi esikhashana, kanye nokulungiswa kokhonkolo olumelana nokushisa.

Ngaphezu kwalokho, ukuxuba i-CalciumAlumina Cement ne-Portland cement noma i-lime akugcini nje ngokukhiqiza ukuqina kwe-flash, kodwa futhi kubangela ukuthi ukhonkolo uqhekeke futhi ubhubhise ngenxa yokwakheka kwe-calcium aluminate enamanzi amaningi e-alkaline. Ngakho-ke, ngaphezu kokuxuba ne-lime noma i-Portland cement ngesikhathi sokwakha, akufanele isetshenziswe lapho ithintana ne-Portland cement engaqinisiwe.

Ekuphetheni, i-Calcium Alumina Cement inikeza inhlanganisela yamandla, ukuguquguquka, kanye nokuqina, okwenza kube yinto ekhethwayo yezidingo zokubopha zezimboni. Kungakhathaliseki ukuthi uhilelekile ekukhiqizweni kwensimbi, amakhemikhali kaphethroli, noma usimende, i-CAC iqinisekisa imiphumela emihle kakhulu. Izakhiwo zayo ezisheshisa, amandla aphezulu okuqala, kanye nokumelana namazinga okushisa aphezulu namakhemikhali kuyenza ibe yimpahla ebalulekile kunoma yimuphi umsebenzi. Khetha i-Calcium Alumina Cement ukuze uthole izixazululo zokubopha ezinamandla nezithembekile ezihlala isikhathi eside.
