摘要
用正交实验方法研究了添加剂及其量、添加方式、温度等对湿法磷酸脱氟和回收氟硅酸钠的影响。结果表明 ,添加剂最好采用碳酸钠 ,添加剂量以 110 - 12 0 %理论用量为宜 ,添加方式采用干粉好些 。
This paper studies the effect of additive and its quantity,additive fashion,and temperature on removal ratio of fluorine and yield of fluosilicate sodium.The result show that it is better to use sodium carbonate as additive,in 110-120% of its theory quantity,in dry powder form,and at a lower temperature.
