Abstract

The invention provides a sodium hypochlorite stabilizer, which is provided with a liquid combination form or a solid combination form. Solid stabilizer comprises the following substances in parts by weight: 1 to 4 parts of sodium phosphate, 1 to 3 parts of disodium hydrogen phosphate, 1 to 3 parts of sodium dihydrogen phosphate and 3 to 7 parts of sodium silicate; the liquid combination form comprises 9 to 13 parts of water on the basis of the solid stabilizer. Four substances are prepared in a given proportion, so favorable factors are maximized and unfavorable factors are minimized, and advantages of each substance are maintained, weaknesses of each substance are overcome, so the stability of the sodium hypochlorite solution can obtain a satisfactory effect.

Description

technical field [0001] The invention relates to a method for jointly preparing a special stabilizer for sodium hypochlorite by using sodium phosphate, disodium hydrogen phosphate, sodium dihydrogen phosphate and sodium silicate, and belongs to the technical field of disinfectants. Background technique [0002] Sodium hypochlorite (NaClO) is a widely used inorganic salt as well as a strong oxidant, bleach, disinfectant and deodorant. Sodium hypochlorite aqueous solution, commonly known as bleaching water, is a by-product of the chlor-alkali industry. It is mainly used for the bleaching of pulp and fabrics, the treatment of upper and lower water, the disinfection and sterilization of hospitals, restaurants, hotels and homes, and is also an important industrial raw material. Currently commercially available industrial sodium hypochlorite is often an aqueous solution with an effective rate of ≥10%, and the aqueous sodium hypochlorite solution will decompose naturally at normal t...
