Umenzi Ixabiso Elilungileyo I-Potassium Hydroxide CAS:1310-58-3
I-Potassium Hydroxide: I-Potassium hydroxide (ifomula yeekhemikhali:KOH, ubuninzi befomula:56.11) umgubo omhlophe okanye i-flake eqinile.Iqondo lokunyibilika liyi-360 ~ 406 ℃, indawo yokubilisa yi-1320 ~ 1324 ℃, ukuxinana kwe-2.044g / cm, i-flash point yi-52 ° F, i-index refractive yi-N20 / D1.421, uxinzelelo lomphunga ngu-1mmHg. (719℃).I-alkaline eyomeleleyo kunye ne-corrosion.Kulula ukufunxa ukufuma emoyeni kunye ne-deliquescence, kunye nokufunxa i-carbon dioxide kwi-potassium carbonate.Inyibilika malunga neengxenye ze-0.6 zamanzi ashushu, iinxalenye ze-0.9 zamanzi abandayo, iinxalenye ezi-3 ze-ethanol kunye ne-2.5 ye-glycerol.Xa inyibilika emanzini, utywala, okanye iphathwa nge-asidi, inani elikhulu lobushushu lenziwa.I-pH yesisombululo se-0.1mol / L yayiyi-13.5.Ubuthi obuphakathi, umthamo obulalayo ophakathi (iigundane, ngomlomo) 1230mg / kg.Inyibilika kwi-ethanol, inyibilika kancinane kwi-ether.Inealkaline ngokugqithisileyo kwaye iyadleka

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