过碳酸钠(2Na_2CO_3·3H_2O_2)俗称固体双氧水,外观为白色自由流动颗粒,是过氧化氢与碳酸钠的加成化合物。过碳酸钠不仅具有液体双氧水的功能,可在较低的水温下迅速分解释放出氧气从而实现漂白、去污、杀菌、除异味等功能,而且它也可同时分解生成碳酸钠。碳酸钠能提高水的 pH,降低硬水中钙、镁离子的浓度,使水软化。过碳酸钠可以被制成各类消毒剂、供氧剂,用于鱼塘水体供氧、工业废水处理、医用消毒、急救等。此外,过碳酸钠也可用于食品漂白、纸浆漂白和纺织印染。
Sodium percarbonate (2Na_2CO_3 · 3H_2O_2) commonly known as solid hydrogen peroxide, the appearance of white free-flowing particles, hydrogen peroxide and sodium carbonate addition compounds. Sodium percarbonate not only has the function of liquid hydrogen peroxide, it can rapidly decompose and release oxygen at lower water temperature to realize the functions of bleaching, decontamination, sterilization and odor removal, and it can also decompose to produce sodium carbonate at the same time. Sodium carbonate can increase the pH of water, reduce the concentration of calcium and magnesium ions in hard water, and soften the water. Sodium percarbonate can be made into various types of disinfectants, oxygen supply, for fish pond water oxygen, industrial wastewater treatment, medical disinfection, first aid and so on. In addition, sodium percarbonate can also be used for food bleaching, pulp bleaching and textile printing and dyeing.
