可以加硫酸钡或者滑石粉做填充,降成本!不能用碳酸钙,并且滑石粉中也不能含有碳酸钙!
另外朋友要注意:在购买硫酸钡时,看是沉淀钡还是天然钡,加工的阻燃PP,沉淀钡颜色要白!
在购买滑石粉时,一定要在正规的厂家,不要有碳酸钙,否则对PP阻燃剂或PP阻燃母粒的阻燃性能影响很大!
沉淀溶液酸度控制在0.05~0.1N,酸度在,硫酸钡溶解度大;酸度小,易引起吸附式共沉淀,使结果偏低 4.根与氯酸根必须赶尽,反复用处理,消除钡盐与硫酸钡共沉淀
鉴定特征:板状晶体,硬度小,近直角相交的完全解理,密度大,遇酸不起泡,并以此与相似的方解石相区别。
开放分类: 化工、重晶石、冶金矿产、石油钻井、添料等等。
氨水加的多溶液会显碱性,导致Ca沉淀不好,加NH4Cl就是用来中和的氧化钙溶解度随温度升高而降低,60℃下比常温沉淀更彻底.
