Umenzi Ixabiso Elihle lePotassium Hydroxide CAS:1310-58-3
I-Potassium Hydroxide: I-Potassium hydroxide (ifomula yekhemikhali: KOH, ubungakanani befomula: 56.11) umgubo omhlophe okanye i-flake solid. Iqondo lokunyibilika yi-360~406℃, iqondo lokubila yi-1320~1324℃, uxinano oluhambelanayo yi-2.044g/cm, i-flash point yi-52°F, i-refractive index yi-N20 /D1.421, uxinzelelo lomphunga yi-1mmHg(719℃). I-alkaline enamandla kwaye iyabola. Kulula ukufunxa umswakama emoyeni nakwi-deliquescence, kwaye ifunxe i-carbon dioxide kwi-potassium carbonate. Inyibilika malunga ne-0.6 yeenxalenye zamanzi ashushu, i-0.9 yeenxalenye zamanzi abandayo, i-3 yeenxalenye ze-ethanol kunye ne-2.5 yeenxalenye ze-glycerol. Xa inyibilikiswa emanzini, kwi-alcohol, okanye inyangwe nge-asidi, kuveliswa ubushushu obuninzi. I-pH yesisombululo se-0.1mol/L yayiyi-13.5. Ityhefu ephakathi, idosi ephakathi ebulalayo (iimpuku, yomlomo) yi-1230mg/kg. Iyanyibilika kwi-ethanol, inyibilika kancinci kwi-ether. Ine-alkaline kakhulu kwaye iyabola

Umenzi Ixabiso Elihle leCalciumAlumina Cement CAS:65997-16-2
I-Calcium I-Alumina Cement yisamente ene-calcium calcium okanye i-calcium aluminium njengeyona nto iphambili kwiiminerali. Yenziwe nge-aluminium yendalo okanye i-alumina yemizi-mveliso kunye ne-calcium carbonate (ilitye lekalika) ngokwemilinganiselo ethile, eyenziwa ngokutshiswa okanye ngokunyibilika ngombane.
Izithako kunye neendidi: I-CalciumAlumina Cement inokwahlulwahlulwa ibe yi-aluminium eqhelekileyo ye-calcium calcium cement (al2O3 53-72%, CAO 21-35%) kunye ne-aluminium ecocekileyo ye-calcium cement (al2O3 72-82%, CAO 19-23%) Iindidi ezimbini. I-aluminium eqhelekileyo yesamente isamente inokwahlulwahlulwa ibe yi-low-iron type (FE2O3 <2%) kunye ne-high-speed rail type (Fe2O37-16%). I-low-rail aluminium yesamente ye-calcium inokwahlulwa ibe yi-alum soil cement (Al2O353 ~ 56%, CAO 33-35%), i-aluminium -60 cement (al2O359%to 61%, CAO 27-31%), kunye ne-low-calcium aluminium acid cement (Al2O3 65-70%, CAO 21 to 24%). Isamente ye-calcium ye-aluminium ecocekileyo inokwahlulwa ibe ziintlobo ezimbini: i-Al2O3 72-78%) kunye ne-aluminium ephezulu kakhulu (Al2O3 78-85%). Ukongeza, kukho isamente ye-calcium ye-aluminium enamandla nekhawulezayo ekuqaleni.I-CAS: 65997-16-2
