Umkhiqizi Intengo Enhle I-Calcium I-Alumina Cement I-CAS: 65997-16-2

incazelo emfushane:

I-Calcium I-Alumina Cement iyisimende esine-calcium calcium noma i-calcium aluminium njengengxenye yayo eyinhloko yamaminerali. Yenziwe nge-aluminium yemvelo noma i-alumina yezimboni kanye ne-calcium carbonate (i-limestone) ngokwesilinganiso esithile, esenziwa ngokushiswa noma ukuncibilika kukagesi.
Izithako nezigaba: I-Calcium I-Alumina Cement ingahlukaniswa ibe yi-aluminium ejwayelekile i-calcium calcium cement (al2O3 53-72%, CAO 21-35%) kanye ne-aluminium emsulwa i-calcium cement (al2O3 72-82%, CAO 19-23%) Izigaba ezimbili. I-aluminium evamile i-cement cement ingahlukaniswa ibe uhlobo lwensimbi ephansi (FE2O3 <2%) kanye nohlobo lwesitimela esinejubane eliphezulu (Fe2O37-16%). I-aluminium i-calcium cement enejubane eliphansi ingahlukaniswa ibe yi-alum soil cement (Al2O353 ~ 56%, CAO 33-35%), i-aluminium -60 cement (al2O359%to 61%, CAO 27-31%), kanye ne-calcium aluminium acid cement ene-calcium ephansi (Al2O3 65-70%, CAO 21 to 24%). Usimende we-calcium we-aluminium omsulwa ungahlukaniswa ngezinhlobo ezimbili: i-Al2O3 72-78%) kanye nohlobo lwe-aluminium oluphezulu kakhulu (Al2O3 78-85%). Ngaphezu kwalokho, kunesimende se-calcium se-aluminium esiqinile nesisheshayo ekuqaleni.

Ukusetshenziswa kwe-CalciumAlumina Cement

I-Calcium I-Alumina Cement isetshenziswa kakhulu njengenhlanganisela yezinto zokuthela ezingaphili kanye nezinto zokufafaza ezingaphili. Kunezidingo ezimbili eziyinhloko ze-aluminium evamile ye-calcium acid cement:
(1) Isikhathi esifanele sokufinyela ukuqinisekisa isikhathi esanele sokusebenza. Ngokuvamile, ukufinyela kokuqala kungaphezu kwehora eli-1 kanti ukufinyela kokugcina kungaphansi kwamahora ayi-8.
(2) Uma inamandla anele okuqala, ingafinyelela ku-60% ~ 70% wamandla ashiwo uphawu lwesimende ngosuku olulodwa, futhi ukulungiswa kungafinyelela ngaphezu kuka-90%.
Ngaphezu kwamaphuzu amabili angenhla, usimende we-aluminium ohlanzekile we-calcium udinga nesilinganiso esithile sokumelana nomlilo kanye nokusebenza kahle ukuze kuhlangatshezwane nezidingo zokwakha kanye nezidingo zokusetshenziswa kwezinga lokushisa eliphezulu.
Ama-castable aqinile angenasici aphakathi nendawo naphansi, njengebumba kanye nama-castable e-aluminium ephezulu, asebenzisa usimende ojwayelekile we-calcium aluminate njenge-binder. Ama-castable aqinile anamandla anjenge-rigid jade, i-mullite, i-chrome-containing rigid jade, i-corundum - spinel castables enziwe nge-calcium aluminate cement emsulwa njenge-binder. Inani lokwengeza lesimende esijwayelekile se-calcium aluminate esingenasici ajwayelekile lingu-10% ~ 20%, inani lokwengeza lesimende esingenasici aphansi angaphansi ngu-5% ~ 7%, kanti inani lokwengeza lesimende esingenasici aphansi angaphansi kuka-3%.
Phakathi kwezinto ezingajwayelekile zokuphikisa, izinto zokuthela izinto zokubopha nge-aluminiumite cement zisetshenziswa kabanzi.
(1) Izinga lokushisa lokusetshenziswa kokunisela ngobumba lingu-1300-1450 degrees. Ngokuvamile lisetshenziswa njengesithando sokushisa sensimbi. Izithando zokushisa ezahlukahlukene, ama-boiler, isithando somlilo esiqondile kanye nesithando somlilo esijikelezayo esifakwe ngaphakathi.
(2) Izinga lokushisa lokusetshenziswa kwezinto zokuthulula i-aluminium ephezulu lingu-1400-1550 degrees, elingasetshenziswa ekwelapheni ukushisa okuhlukahlukene kolwelwesi lwesithando somlilo kanye nomlomo ovuthayo. Izithando zikagesi, izingxenye zokushisa okuphezulu zesithando somlilo esiqondile, ikhanda lesithando somlilo esijikelezayo, kanye nolwelwesi lwebhoyila yesitshalo samandla.
(3) Izinga lokushisa lokusetshenziswa kweGang Jade Water lingama-degrees angu-1500-1650, elisetshenziswa kakhulu emzimbeni wolwelwesi lwama-furnace ahlukahlukene okushisa okuphezulu kanye nezingxenye zokushisa okuphezulu ukuthenga amadivayisi angangenisi amanzi ensimbi. Umugqa, ulwelwesi endaweni ephezulu engunxantathu yesithando sikagesi, isembozo sesithando se-LF, kanye nolwelwesi olungagugi lokushisa oluphezulu lwe-reactor ye-petrochemical industrial catalytic cracking.
