A kiln used to reduce naturally occuring forms of calcium carbonate to lime. Limestone is rock composed of calcium carbonate. 用来使碳化钙和石灰自然成形的窑。石灰石是由碳酸钙所构成的岩石。
Heat balancing of kiln and furnace for lime a kiln used to reduce naturally occuring forms of calcium carbonate to lime. 烧石灰用立窑热平衡测定与计算方法用来使碳化钙和石灰自然成形的窑。
Experiments show that causticizing by adding a small quantity of slaked lime can eliminate the interference of carbonate ions and humic acid salts. 添加少量的熟石灰可即刻消除碳酸根和腐植酸盐等有机杂质的影响。
It is well known fact that reactivity of char surface can be improved through various processes including stream treatment ( activated carbon) or treatment with lime and sodium carbonate. 这是众所周知的事实,表面反应的字符,可以通过各种治疗,包括流过程改进(活性炭),或用石灰和碳酸钠治疗。
Thus amendments of lime, calcium cyanamide or sodium carbonate to adjust soil pH value to 7 is practiced to control the disease. 实践中,石灰,石灰氮,碳酸钠皆可用来向病田土壤中添加,以使土壤pH值调整到≥7.0,并成为本病防治的主要方法。
As may be expected, the XRD results show that the most significant metal composition in the sludge obtained from the three precipitants ( lime, Sodium carbonate and Sodium sulfide) was the metal hydroxide, metal carbonate and metal sulfide respectively. 正如预料的那样,XRD实验结果表明,用这三种沉淀剂(氢氧化钙,碳酸钠和硫化钠)获得金属污泥的主要成分分别是金属氢氧化物,金属碳酸盐和金属硫化物。
The prepared acidic contaminated water was placed in each beaker and various dosages of lime, soda ash and sodium sulfide powders were added to precipitate the heavy metal as metal hydroxide, carbonate and sulfide respectively. 将准备好的酸性污染水放到每个烧杯中,加入不同剂量的氢氧化钙,碳酸钠和硫化钠粉末,使重金属以金属碱化物,盐化物和硫化物的形式沉淀出来。
