Preparation method and product of stable chlorine dioxide

Abstract

The invention discloses a preparation method of stable chlorine dioxide. The chlorine dioxide gas can be used to prepare stable chlorine dioxide which has good stability and can be stored for long term. Sodium phosphate and hydrogen peroxide are used as basic components for stabilizing chlorine dioxide, and can have self-stabilization function in the absorption process and efficiently absorb chlorine dioxide to form a stable chlorine dioxide solution. The prepared product has the following advantages: the content of active chlorine dioxide is high, the stability is good, the production cost is low, the operations are convenient, other stabilizers are not required to be added in production, the storage stability is good, the product is safe in use and the like. When in use, an acid activator is added in the product to generate chlorine dioxide gas. The prepared stable chlorine dioxide has good slow release property; and according to the type and concentration of the used acid activator, the slow release of the product can be easily controlled, chlorine dioxide can be released thoroughly and the utilization rate is high. The product can be widely used in the disinfection, sterilization, preservation, deodorizing and the like of various industries.

Description

Technical field: [0001] The invention belongs to the field of a new generation of sterilization, disinfection and antistaling agent-chlorine dioxide and stable chlorine dioxide. The invention can prepare the chlorine dioxide gas into a stable chlorine dioxide solution with good stability and long-term storage. Background technique: [0002] The preparation of stable chlorine dioxide solution is usually made by absorbing chlorine dioxide gas with a stable solution prepared by sodium percarbonate, sodium perborate, sodium carbonate and hydrogen peroxide. Although the stable chlorine dioxide solution prepared by the above-mentioned absorption liquid has been applied in many industries, there are also some problems. Because the stability of multiple chlorine dioxide needs to be added in the preparation process, the product is in some fields. For example, the use in the food industry is limited, and at the same time, such stable chlorine dioxide solutions usually have short stab...

Problems solved by technology

Although the stable chlorine dioxide solution prepared by the above-mentioned absorption liquid has been applied in many industries, there are also some problems. Because the stability of multiple chlorine dioxide needs to be added in the preparation process, the product is in some fields. For example, the use in the food industry is limited, and at the same time, such stable chlorine dioxide solutions usually have short stability periods and are easily decomposed and deactivated, which also affect their application in some fields.
