摘要
综述了近几年来国内外过碳酸钠制备、生产和应用发展概况。制备方法包括化学合成、晶体造粒和性能改进等,但研究重点集中在产品改性即产品稳定化方面,主要采取颗粒表面包覆技术。由于该产品的需求不断增长,国外主要生产公司均在扩产,尤其在美国和欧洲。过碳酸钠传统主要用于粉状洗涤剂中,作为漂白和消毒组分;但近年来各有关公司进行了不少新的应用研究,将其配制成高效清洁剂,将其用于液体洗涤剂,将其制成可用作水体增氧剂的固体制剂等,从而扩大产品应用范围。
The development in recent years of preparation method, production and application of sodium percarbonate at home and abroad is reviewed.The preparation method includes chemical synthesis, crystal granulation and property modification etc.However, the research is emphatically aimed at stabilization ofproduct.＇The main measure for this is coating the surface of product particles. Recently, the main production companies in the world,especially in America and Europe,have expanded their production capacity to meet the increasing need.A great amount of sodium percarbonate is traditionally used in detergent powders as bleaching and disinfecting agent.But recently relevant companies have developed some new applications including use as effective cleaning agent,use in liquid detergent, use as oxygen-enriching agent in water system, etc.All of the above-mentioned research and development are introduced.
