摘要
在含有氯化钠、稳定剂、结晶改良剂的过氧化氢水溶液中,加入饱和碳酸钠溶液,直接反应生成粒状过碳酸钠。该方法工艺简单、技术可行、无需造粒工序。可以制得流动性好、活性氧含量高、高堆积密度的过碳酸钠产品,采用盐析法可提高产品的收率。
In hydrogen peroxide soiution including sodium chloride, stabilizer, crystal modifier , the saturated sodium carbonate solution is added to form into granular sodium percarbonate. The process is simple and feasible , no need for prilling procedure. The product will have good fluidity , high content of active oxygen and high bulk density , the yield can be improved by salting-out method .
