PLC Application in the Electrical Control System of Gas Burned Active Lime Kiln PLC在气烧活性石灰窑电气控制系统中的应用
In this paper, we discuss the hydration mechanism of anhydrite ⅱ, study accelerating actions anhydrite ⅱ with different accelerating agent, fabricate the white anhydrite cement adding burned alunite and assimilation lime as the accelerating agents. 在探讨AⅡ无水石膏水化机理的基础上,研究了不同激发剂对AⅡ无水石膏的激发作用,采用内掺煅烧明矾石和消石灰制成了硬石膏白水泥。
The results showed that refuse sugarbeet lime, burned lime and sewage sludge significantly increased wheat yield. 试验结果表明施用废弃的甜菜石灰、熟石灰和污水沉泥较大地提高了小麦产量。
In laboratory, through the use of Al 2O 3 and CaO for raw materials, the hydrated calcium aluminate was synthesized by hydro thermal treatment at normal pressure; then it was burned at low lime aluminate cement. 采用Al2O3和CaO为原料,在实验室常压下水热合成水化铝酸钙,然后低温煅烧制备活化低钙铝酸钙水泥。
