Umenzi wexabiso eliLungileyo iCalciumAlumina Cement CAS:65997-16-2

inkcazelo emfutshane:

I-CalciumAlumina Cement yisamente ene-calcium calcium okanye i-calcium aluminiyam njengenxalenye yayo yeminerali.Yenziwe nge-aluminiyam yendalo okanye i-alumina ye-industrial kunye ne-calcium carbonate (i-limestone) ngokomlinganiselo othile, owenziwe ngokutshisa okanye ukunyibilika kombane.
Izithako kunye neendidi: I-CalciumAlumina Cement inokwahlulwa ibe yi-aluminium eqhelekileyo ye-calcium i-samente ye-calcium (al2O3 53-72%, i-CAO 21-35%) kunye ne-aluminium ecocekileyo ye-samente ye-aluminium (al2O3 72-82%, CAO 19-23%) Iindidi ezimbini.I-aluminiyam eqhelekileyo yesamente yesamente inokwahlulwa ibe yi-iron ephantsi (FE2O3 <2%) kunye nohlobo lwe-high-speed rail (Fe2O37-16%).Umzila ophantsi-uhlobo lwe-aluminium -uhlobo lwesamente ye-calcium inokwahlulwa ibe yi-alum yomhlaba isamente (Al2O353 ~ 56 %, CAO 33-35%), i-aluminium -60 i-samente (al2O359% ukuya kwi-61%, i-CAO 27-31%), kwaye iphantsi. -i-calcium aluminium i-samente ye-asidi (Al2O3 65-70%, i-CAO 21 ukuya kwi-24%).I-aluminium ecocekileyo ye-samente ye-calcium ingahlulwa ibe ziindidi ezimbini: i-Al2O3 72-78%) kunye ne-ultra-high aluminium uhlobo (Al2O3 78-85%).Ukongeza, kukho i-samente ye-aluminiyam calcium ekhawulezayo kwaye eqinile.

Ukusetyenziswa kweCalciumAlumina Cement

I-CalciumAlumina Cement isetyenziswa ikakhulu njengendibaniselwano yokugalela okuchasayo kunye nezixhobo zokutshiza.Kukho iimfuneko ezimbini eziphambili zesamente ye-aluminiyam ye-calcium acid:
(1) Ixesha elifanelekileyo lokuthomalalisa ukuqinisekisa ixesha elaneleyo lokusebenza.Ngokuqhelekileyo, i-condensation yokuqala inkulu kune-1h kwaye i-condensation yokugqibela ingaphantsi kwe-8h.
(2) Ngokuqina okwaneleyo kwangaphambili, kunokufikelela kwi-60% ~ 70% yamandla achazwe ngummakishi wesamente ngosuku olunye, kwaye ukugcinwa kunokufikelela ngaphezu kwe-90%.
Ukongeza kula manqaku mabini angentla, i-calcium ecocekileyo ye-aluminium i-samente ifuna kwakhona umlinganiselo othile wokumelana nomlilo kunye nokusebenza kakuhle kokusebenza ukuhlangabezana neemfuno zokwakha kunye neemfuno zokusetyenziswa kokushisa okuphezulu.
Izinto ezinqatyisiweyo ezinqambileyo zomgangatho ophakathi kunye nomgangatho ophantsi, njengodongwe kunye ne-aluminium ephezulu yokuphosa, sebenzisa i-samente ye-calcium aluminate njenge-binder.Umgangatho ophezulu we-refractory castables ezifana ne-jade eqinile, i-mullite, i-chrome-equlethe i-jade eqinile, i-corundum - i-spinel castables yenziwe nge-samente ye-calcium aluminate ecocekileyo njenge-binder.Isixa esongeziweyo se-samente ye-aluminate ye-samente ye-refractory eqhelekileyo yi-10% ~ 20%, isixa-mali esongezelelweyo se-samente ephantsi ye-refractory castable yi-5% ~ 7%, kunye nemali eyongezelelweyo ye-ultra-low cement castable ingaphantsi kwe-3%.
Phakathi kwezinto ezichaseneyo ezingaqhelekanga, izinto zokuthululela ama-agent abophezelayo nge-samente ye-aluminium zisetyenziswa ngokubanzi.
(1) Ubushushu bokusetyenziswa kokunkcenkceshela ngodongwe yi-1300-1450 degrees.Ngokuqhelekileyo isetyenziswa njengesithando somlilo sentsimbi.Iziko lonyango olushushu olwahlukeneyo, iibhoyila, iziko elithe nkqo kunye ne-rotary kiln lined.
(2) Ubushushu bokusetyenziswa kwezixhobo zokugalela i-aluminiyam ephezulu yi-1400-1550 degrees, enokuthi isetyenziswe kwi-thermal treatment lining yesithando somlilo kunye nomlomo ovuthayo.Iziko lombane, amacandelo anobushushu obuphezulu ekalika ethe nkqo kwikontini, intloko yebhoyila ejikelezayo, kunye nebhoyila yeplanti yombane.
(3) Ubushushu bokusetyenziswa kweGang Jade Water yi-1500-1650 degrees, esetyenziswa kakhulu kwi-lining body of furnaces ezahlukeneyo zobushushu obuphezulu kunye namacandelo aphezulu obushushu bokuthenga izixhobo zentsimbi zokufunxa amanzi.Umgca, umgca kwindawo ephezulu ye-triangular yesithando sombane, isigqubuthelo sesithando somlilo seLF, kunye nobushushu obuphezulu obunganyangekiyo kwilayini yepetrochemical industrial catalytic cracking reactor.
