Problems solved by technology

However, because chlorine dioxide is a very active and unstable yellow-green gas, and the solution is volatile, it is usually inconvenient to make compressed gas or concentrated solution, which greatly reduces the convenience of chlorine dioxide.
[0005] At present, the existing technology is to use diatomite, kaolin, clay, bentonite, and sodium silicate as adsorbents or binders to absorb a stable chlorine dioxide solution, and then dry and press to obtain chlorine dioxide disinfection particles. The disinfection granules produced by this method are easy to absorb water and swell in a high-humidity environment (generally referring to a relative humidity greater than 80%), destroying the strength of the granules, and breaking the sustained-release state of the granules, thereby limiting its application in a high-humidity environment

preparation example Construction

[0061] The present invention provides the preparation method of solid-carried chlorine dioxide air disinfection granules described in the above scheme, comprising the following steps:

[0062] Mix the raw materials corresponding to the composition of the inner core with water, use a dry granulator to granulate the obtained mixture, and obtain the inner core granules after drying;

[0063] The raw materials corresponding to the shell components are mixed with water to obtain a coating solution; the inner core particles are coated with the coating liquid to form a shell layer on the surface of the inner core particles, and after drying, solid-carried chlorine dioxide air disinfection granules are obtained.

[0064] The invention mixes raw materials corresponding to the composition of the inner core with water, uses a dry granulator to granulate the obtained mixture, and obtains inner core particles after drying.

[0065] Before mixing, the present invention preferably grinds the...

Embodiment 1

[0084] Embodiment 1 (containing humidity-conditioning agent)

[0085] The core composition is: 72 parts of curing agent (specifically: 55 parts of dicalcium silicate, 10 parts of tricalcium silicate, 5 parts of calcium sulfate, 1 part of tricalcium aluminate, 1 part of zeolite), the first chlorine dioxide generator 10 parts (specifically: 5 parts of sodium chlorite, 5 parts of potassium chlorite), 5 parts of filler (specifically: 2 parts of calcium bicarbonate, 3 parts of diatomaceous earth), 3 parts of fragrance (specifically, 3 parts of lavender essence ), 5 parts of coloring agent (5 parts of iron yellow), 3 parts of first sustained-release agent (specifically: 2 parts of hydroxypropyl methylcellulose, 1 part of polyethylene glycol 80001), 4.5 parts of activator (specifically: : 1 part of citric acid, 1 part of sodium percarbonate, 1.5 parts of potassium dihydrogen phosphate, 1 part of disodium hydrogen phosphate);

[0086] The shell is composed of: 70 parts of the second ...

Embodiment 2

[0093] Embodiment 2 (does not contain humidity conditioner)

[0094] The difference from Example 1 is that there is no humidity-conditioning agent in the shell, and the colorant is changed from iron yellow to cobalt blue.

Abstract

The invention provides a solid-carrying chlorine dioxide air disinfection granule and its preparation method and application, belonging to the technical field of air purification disinfectants. The solid-carried chlorine dioxide air disinfection granules of the present invention contain a curing agent. In a high-humidity environment, the strength of the solid-carried chlorine dioxide air disinfection granules will basically not change due to the presence of the curing agent, and the particle strength will not be reduced due to high moisture. The strength makes the granules broken and soft, so the solid-carried chlorine dioxide air disinfection granules of the present invention can be used in high-humidity environments (relative humidity > 80%) for disinfection, sterilization and deodorization. The present invention can be used in an environment with a relative humidity of 10-100% by using a humidity-regulating agent in the shell; when the humidity-regulating agent is not used, it can be used in an environment with a relative humidity of 30-100%.

Description

technical field [0001] The invention relates to the technical field of air purification and disinfectants, in particular to a solid-carried chlorine dioxide air disinfection granule, a preparation method and application thereof. Background technique [0002] With the rapid development of the economy and the continuous improvement of living standards, people have higher and higher requirements for the comfort and aesthetics of the living environment and working environment. At the same time, it also brings a series of problems to control indoor air pollution. [0003] At present, indoor pollutants mainly include formaldehyde, benzene, ammonia, radon, aromatic hydrocarbons, tetrachloroethylene, p-dichlorobenzene, chlorine, carbon monoxide, hydrogen sulfide, organic amines, mercaptans and sulfides. These pollutants and various pathogenic microorganisms in the air not only affect people's mood, but also pose a great threat to people's health. There are many kinds of air purifie...
