Embodiment 1

[0022] Example 1: Including the following raw materials in parts by weight: 48 parts of sucrose, 1.1 parts of sodium chlorate, 20 parts of sulfuric acid, which are used to prepare high-purity chlorine dioxide gas in advance. The high-purity gas can be produced to a high Concentration of chlorine dioxide solution to obtain high-purity chlorine dioxide solid particles.

Embodiment 2

[0023] Example 2: The raw materials of sucrose are mainly sugar cane and sugar beet. The sugar cane or sugar beet is crushed by a machine, the sugar juice is collected, filtered and treated with lime to remove impurities, and then bleached with sulfur dioxide, the processed sugar juice is boiled and removed The impurities that sink to the bottom are scraped off the foam that floats to the water surface, and then the heat is turned off until the syrup crystallizes into high-purity sucrose, which is the main raw material for preparing chlorine dioxide gas; sodium chlorate is colorless crystals or white particles, stored in a cool and dry place The sodium chlorate in the place is taken according to the ratio and reacted with sucrose and sulfuric acid as the main raw material for the production of sulfur dioxide gas; sulfuric acid is a concentrated sulfuric acid with a mass fraction of 98.3% obtained by the contact method; sucrose, sodium chlorate and sulfuric acid The reaction equa...

Embodiment 3

[0024] Example 3: The high-purity chlorine dioxide solution, sustained-release agent, and flavor are reacted at a ratio of 0.25, 0.7, and 0.05 at 0-9 degrees Celsius. The raw materials of the sustained-release agent are ethyl cellulose and cellulose acetate The microporous structure formed by the mixture with polyethylene and slow release agent substrate slows down the volatilization rate of liquid chlorine dioxide and greatly increases the diffusion resistance, so that the total effective release time of the present invention can reach two and a half months, and the release rate is gentle After the sustained-release agent mixture is formed, it fully reacts with chlorine dioxide solution at 0-9 degrees Celsius. The sustained-release agent mixture swells. The flavor used is powder flavor, which is made by grinding and mixing solid flavors, mainly fruit Fragrance, non-toxic and harmless, can make chlorine dioxide solid particles emit fruity aroma, the mixture of powder flavor, slo...

Abstract

The invention discloses sustained-release chlorine dioxide air disinfection particles and a preparation method thereof which relate to the technical field of gas disinfection, and comprises the following raw materials in parts by weight: 48 parts of cane sugar, 1.1 parts of sodium chlorate and 20 parts of sulfuric acid, and for the method comprises the following steps: preparing high-purity chlorine dioxide gas in advance, wherein the raw materials of sucrose are mainly sugar cane and beet, crushing the cane sugar or beet by using a machine, collecting sugar juice, filtering, treating by usinglime, and removing impurities. The chlorine dioxide air disinfection particles and the preparation method thereof have the advantages that the chlorine dioxide air disinfection particles have a greatmarket prospect and is high in conversion rate and purity of generated chlorine dioxide, so that the generated chlorine dioxide disinfection particle is high in purity and good in disinfection effect, and the problem that an existing preparation method is poor in purity and disinfection effect of chlorine dioxide disinfection particles is solved; the continuous disinfection capability is realized, the cost performance is high, and the problems that the existing volatilization speed is high, the continuous disinfection capability is not realized, and the cost performance is low are solved.

Description

Technical field [0001] The invention relates to the technical field of gas disinfection, in particular to a long-lasting slow-release chlorine dioxide air disinfection particle and a preparation method thereof. Background technique [0002] In the indoor spaces of homes, hotels, office buildings, schools, hospitals, restaurants, KTV rooms, stations, terminal buildings, etc., clean air directly affects people’s health. Therefore, it is necessary to sterilize and disinfect the indoor environment regularly to ensure The indoor environment is hygienic and clean to prevent residents or the public from being harmed by poisonous and harmful gases or viruses and other pathogenic substances that affect their health or suffer from diseases. Existing indoor air disinfection methods mainly use sprayers to spray disinfectant or use disinfectant to directly wipe indoor objects; or use air purifiers to filter the room through circulation and use ultraviolet rays or disinfectant for biocidal kil...
