摘要
通过试验,研究了温度对氯化钾芒硝转化法制取硫酸钾的影响试验指出,在20℃,30℃,40℃,50℃,60℃温度范围内,随温度升高,半成品钾芒硝和产品硫酸钾的Cl-含量升高,K+含量降低温度高于30℃时。
The effect of temperature on production of K 2SO 4 from KCl and Na 2SO 4 has been studied under the conditions of laboratory experiments.The results show that when temperature rises among 20~60 ℃,the contents of Cl - in semi-finished products 3K 2SO 4·Na 2SO 4 and product K 2SO 4 are raised,the contents of K + in that are decreased.When temperature exceeds 30 ℃,the product K 2SO 4 is not up to the first-rate product of ZBG21006-89.
