potassium carbonate 碳酸鉀。

potassium chlorate

Taking the lest total internal losing exergy for target function , the distribute of difference in temperature among the three - effect is also acquired . an experimental device for three - effect falling - film evaporation was designed and constructed . the experiments of potassium carbonate solution was finished under different temperature of vapor and different input material liquid volume 建立了三效降膜蒸發的實驗裝置,以碳酸鉀溶液為原料進行了不同加熱蒸汽溫度、不同進料量的實驗研究,得到了實驗設備的(火用)損分布,并研究了各部分損失的(火用)及有效利用的(火用)值與加熱生蒸汽溫度與進料量的關系。

In comparison with sol - gel system catalyzed by potassium carbonate and sodium carbonate , the gel time was markedly shortened and the densities of the prepared carbon aerogels were obviously reduced 相對以k _ 2co _ 3和na _ 2co _ 3為催化劑的凝膠體系,凝膠化時間大大縮短,所得氣凝膠密度降低。
