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 lunokwahlulwa lube yi-alum yomhlaba isamente (Al2O353 ~ 56%, CAO 33-35%), i-aluminium -60 yesamente (al2O359% ukuya kwi-61%, i-CAO 27-31%), kunye ne-calcium ephantsi ye-aluminiyam i-samente ye-asidi, i-5O20% ye-samente ye-calcium, i-5O20% ye-3% ye-520% (Al-2O20%). 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 yokugalelwa kwe-refractory 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.
