Problems solved by technology

[0004] There are also bibliographical reports on the preparation of the stable chlorine dioxide powder disinfectant of binary packaging at present, but basically solid sodium chlorite adds some such as sodium chloride or sodium bicarbonate to form stabilizers and some liquid inorganic acids such as hydrochloric acid as For binary packaging products such as activators, the biggest disadvantage of this type of product is that hydrochloric acid itself is corrosive and requires a closed environment during operation, and operators need to wear self-priming filter gas masks, acid and alkali resistant clothing, and Acid and alkali-resistant gloves, keep away from flammable and combustible materials, and avoid contact with alkalis, amines, and alkali metals
And it is very inconvenient for users to purchase and use
Therefore, the promotion and application of the product are limited

Abstract

The invention discloses reactive chlorine dioxide powder in binary packing and its preparation method. The powder comprises individually packed powder A and powder B, wherein, the powder A consists of: 70-90 wt% of a native agent, 10-30 wt% of a stabilizing agent, and the powder B consists of: 60-80 wt% of an acidifying agent, 10-20 wt% of a catalyst, and 10-20 wt% of a foaming agent. The preparation method includes: grinding each raw material substances and sieving them through a sieve of 100-120 meshes, reserving the raw material substances of an intermediate particle size, and drying them at a temperature of 40-120DEG C respectively, then weighing the corresponding mass parts of substances of powder A and powder B respectively, and respectively conducting uniform mixing, drying, and packaging, thus obtaining binary reactive chlorine dioxide powder A and powder B. The powder of the invention is characterized by convenient transportation and usage, simple and practical operation, good stability and high conversion rate.

Description

technical field [0001] The invention belongs to the technical field of chlorine dioxide disinfection, in particular to a binary reaction type chlorine dioxide powder composed of sodium chlorite, solid acid and other accelerators, and the invention also relates to a preparation method of the powder. Background technique [0002] As a water-soluble strong oxidant, chlorine dioxide has high-efficiency and broad-spectrum bactericidal ability. It can kill microorganisms such as bacteria and viruses, as well as oxidatively decompose amino acids and other reducing substances in proteins. ions react; and, compared with other chlorine-based products, chlorine dioxide does not produce teratogenic, carcinogenic, mutagenic chloroform and other organic halides during sterilization, and the effects of killing viruses, bacteria, deodorizing, bleaching, etc. are Cl 2 2.5 times higher than that, and the World Health Organization (WHO) classifies its safety as A1. Based on the oxidative and...
