2.
In the wet-process phosphoric acid production from the Hubei phosphate ore, one of the bothersome problems is that potassium fluosilicate and sodium fluosilicate scales are liable to form on the filtration system owing to its high potassium and sodium content, which greatly restrains the application of Hubei phosphate ore.
本文首先采用人工冷却系统模拟湿法磷酸生产的真空过滤系统冷却过程,研究垢物的析出规律,实验结果得知:垢物的主要成分为氟硅酸钠和氟硅酸钾,氟硅酸钠首先析出,结构致密,其次是氟硅酸钾,最后是二水硫酸钙,氟硅酸钠对氟硅酸钾有很强的结晶诱导作用;然后在三种生产中常用的不同的材质钼二钛、聚氯乙烯和聚四氟乙烯表面进行结垢试验,发现聚四氟乙烯表面最不易结垢,而在钼二钛表面最易结垢。
补充资料:六氟铪酸钾
分子式: K2HfF 
CAS号:

性质:无色晶体物,斜方晶结构。熔点802℃。不易潮解,在空气中稳定。易溶于水,溶解度受温度影响大,100g水中25℃时溶解4.61g,100℃时溶解74.1g,溶解度比六氟锆酸钾高很多,冶金中利用这一差别分离锆和铪。将氢氧化铪溶于氟化氢和氟化钾溶液中结晶析出。作为电解法制取金属铪的原料。
