Umkhiqizi Intengo Enhle I-Potassium Hydroxide CAS:1310-58-3
I-Potassium Hydroxide : I-Potassium hydroxide (ifomula yamakhemikhali :KOH, inani lefomula :56.11) impushana emhlophe noma i-flake eqinile.Iphuzu elincibilikayo lingu-360 ~ 406℃, indawo yokubilisa ngu-1320 ~ 1324℃, ukuminyana okuhlobene ngu-2.044g/cm, i-flash point ngu-52°F, inkomba ye-refractive ngu-N20/D1.421, umfutho we-vapor ngu-1mmHg (719℃).I-alkaline enamandla futhi iyagqwala.Kulula ukumunca umswakama emoyeni kanye ne-deliquescence, futhi imunce isikhutha ku-potassium carbonate.Incibilika ezingxenyeni ezingaba ngu-0.6 zamanzi ashisayo, izingxenye ezingu-0.9 zamanzi abandayo, izingxenye ezi-3 ze-ethanol nezingxenye ezingu-2.5 ze-glycerol.Uma kuchithwa emanzini, utshwala, noma ukuphathwa nge-asidi, inani elikhulu lokushisa liyakhiqizwa.I-pH yesisombululo esingu-0.1mol/L yayingu-13.5.Ubuthi obumaphakathi, umthamo obulalayo ophakathi (amagundane, ngomlomo) 1230mg/kg.Incibilika ku-ethanol, inyibilika kancane ku-ether.Ine-alkaline ngokwedlulele futhi iyagqwalisa

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