Umkhiqizi Intengo Enhle I-CalciumAlumina Cement CAS:65997-16-2

incazelo emfushane:

I-CalciumAlumina Cement iyisimende ene-calcium calcium noma i-calcium aluminium njengengxenye yayo eyinhloko yamaminerali.Yenziwe nge-aluminium yemvelo noma i-alumina yezimboni kanye ne-calcium carbonate (i-limestone) ngokwengxenye ethile, eyenziwa ngokushiswa noma ukuncibilika kukagesi.
Izithako nezigaba: I-CalciumAlumina Cement ingahlukaniswa ibe yi-aluminium evamile ye-calcium kasimende (al2O3 53-72%, i-CAO 21-35%) kanye ne-aluminium ehlanzekile ye-calcium usimende (al2O3 72-82%, CAO 19-23 %) Izigaba ezimbili.I-aluminium evamile usimende ingahlukaniswa ngohlobo lwe-iron ephansi (FE2O3 <2%) kanye nohlobo lwesitimela esinesivinini esikhulu (Fe2O37-16%).I-Low-rail -ihlobo lwe-aluminium -uhlobo lwe-calcium usimende ingahlukaniswa kusimende wenhlabathi ye-alum (Al2O353 ~ 56 %, CAO 33-35%), i-aluminium -60 usimende (al2O359% kuya ku-61%, i-CAO 27-31%), futhi iphansi -calcium aluminium acid usimende (Al2O3 65-70%, CAO 21 kuya 24%).I-aluminium ehlanzekile ye-calcium usimende ingahlukaniswa ngezinhlobo ezimbili: i-Al2O3 72-78%) kanye nohlobo lwe-aluminium oluphezulu kakhulu (Al2O3 78-85%).Ngaphezu kwalokho, kukhona usimende we-calcium we-calcium oqinile futhi oqinile wangaphambi kwesikhathi.

Izicelo zeCalciumAlumina Cement

I-CalciumAlumina Cement isetshenziswa kakhulu njengenhlanganisela yokuthela okuphikisayo kanye nezinto zokufafaza eziphikisayo.Kunezidingo ezimbili eziyinhloko zikasimende ojwayelekile we-aluminium calcium acid:
(1) Isikhathi esifanelekile sokuminyanisa ukuze kuqinisekiswe isikhathi esanele sokusebenza.Ngokuvamile, ukufingqa kokuqala kukhulu kune-1h futhi ukufingqa kokugcina kungaphansi kuka-8h.
(2) Ngokuqina okwanele kwangaphambi kwesikhathi, kungafinyelela ku-60% ~ 70% wamandla ashiwo umaka usimende usuku olulodwa, futhi ukugcinwa kungafinyelela ngaphezu kwama-90%.
Ngaphezu kwamaphuzu amabili angenhla, usimende we-aluminium ohlanzekile we-calcium nawo udinga inani elithile lokumelana nomlilo nokusebenza okuhle kokusebenza ukuze kuhlangatshezwane nezidingo zokwakha kanye nezidingo zokusetshenziswa kwezinga lokushisa eliphezulu.
Ama-castable e-refractory esezingeni eliphakathi neliphansi, njengobumba nezinsimbi ezisansimbi eziphezulu ze-aluminium, zisebenzisa usimende ojwayelekile we-calcium aluminate njengesibophezelo.Ama-castable e-high-grade refractory afana ne-jade eqinile, i-mullite, i-chrome-containtain rigid jade, i-corundum - i-spinel castables yenziwe ngosimende omsulwa we-calcium aluminate njenge-binder.Inani elingeziwe likasimende we-calcium aluminate we-refractory ojwayelekile owenziwe ngensimbi ngu-10% ~ 20%, inani elingeziwe le-cast-refractory eliphansi likasimende lingama-5% ~ 7%, futhi inani elingeziwe likasimende olahlekayo we-ultra-low lingaphansi kuka-3%.
Phakathi kwezinto eziphikisayo ezingavamile, izinto zokuthululela ama-agent abophayo nge-aluminium simende zisetshenziswa kabanzi.
(1) Izinga lokushisa lokusebenzisa lokunisela ngobumba yi-1300-1450 degrees.Ngokuvamile isetshenziswa njengesithando somlilo sensimbi.Izinhlobo ezahlukene zokushisa ezishisayo, ama-boilers, ihhonela elime mpo kanye neziko elijikelezayo elifakwe ulayini.
(2) Izinga lokushisa elisetshenziswayo lezinto zokuthulula eziphezulu ze-aluminium zingama-degree angu-1400-1550, angasetshenziswa ulwelwesi oluhlukahlukene lwesithando somlilo nomlomo ovuthayo.Izithando zomlilo zikagesi, izingxenye ezishisa kakhulu zokushisa kwe-lime, i-rotary kiln head, kanye nolayini lukabhayela wezitshalo zamandla.
(3) Izinga lokushisa lokusebenzisa i-Gang Jade Water lingama-degree angu-1500-1650, asetshenziswa kakhulu emzimbeni wolwelwesi lwezithando zokushisa eziphakeme ezihlukahlukene kanye nezingxenye ezishisa kakhulu zokushisa ukuze kuthengwe amadivaysi ensimbi angangenisi amanzi.Ulayini, ulayini endaweni engunxantathu ephezulu yesithando somlilo sikagesi, ikhava yesithando somlilo se-LF, kanye nolwelwesi olumelana nokushisa okuphezulu kwe-petrochemical industrial catalytic cracking reactor.
