摘要
本文研究了温度和盐基度指标对以钛白副产硫酸亚铁为主要原料的聚合硫酸铁稳定性的影响。结果表明,盐基度为10%的产品,常温放置的稳定性较好,若在散热不好的设施中储存,可以采用降低盐基度的方式来提高产品的稳定性。
The effects of temperature and basicity index on the stability of polymeric ferric sulfate with ferrous sulfate as the main raw material were studied. The results showed that the product with 10% basicity had good stability at room temperature. In storage facilities with poor heat dissipation, the method of reducing basicity could be improved the product stability.
