Embodiment 1

[0032] The invention relates to a slow-release chlorine dioxide disinfection and purification powder and a preparation method thereof, which overcomes the defect in the prior art that the production process of the slow-release chlorine dioxide air disinfectant is complicated by using silica gel as a colloid, and provides A powder product form has been developed. This powder product can absorb and react to remove harmful substances such as formaldehyde. It has the functions of purifying the air, killing bacteria in the air, and removing odors from the air. It is mainly used as an air disinfectant and purifier.

[0033] In this embodiment, the formulation of the slow-release chlorine dioxide disinfection and purification powder mainly consists of 10% chlorine dioxide precursor, 20% activator, 5% slow-release agent, 12% gel, 45% Filler, 8% inert composition.

[0034] Make it through the following steps:

[0035] A: Prepare materials, prepare chlorine dioxide precursor, activator...

Embodiment 2

[0045] In this embodiment, the formulation of the slow-release chlorine dioxide disinfection and purification powder mainly consists of 5% chlorine dioxide precursor, 12% activator, 10% slow-release agent, 20% gel, 43% Filler, 10% inert composition.

[0046] Make it through the following steps:

[0047] A: Prepare materials, prepare chlorine dioxide precursor, activator, slow-release agent, gel, filler and inert agent respectively:

[0048] The chlorine dioxide precursor selects powdered sodium chlorite for use; the activator selects powdered sodium bisulfate for use; the purpose of the slow-release agent is to control the rate of moisture absorption, and has the effect of slowly absorbing moisture. In the actual preparation process, Powdered polyethylene glycol can be used; powdered AQUAGEL PLUS gel can be used as gel agent; powdered anhydrous sodium sulfate can be used as filler; activated carbon can be used as inert agent.

[0049] B: Drying: Put the chlorine dioxide prec...

Embodiment 3

[0057] In this embodiment, the formulation of the slow-release chlorine dioxide disinfection and purification powder mainly consists of 8% chlorine dioxide precursor, 16% activator, 8% slow-release agent, 16% gel, 47% Filler, 5% inert composition.

[0058] Make it through the following steps:

[0059] A: Prepare materials, prepare chlorine dioxide precursor, activator, slow-release agent, gel, filler and inert agent respectively:

[0060] The chlorine dioxide precursor is selected from powdered sodium chlorite, potassium chlorite and barium chlorite, and the ratio of sodium chlorite: potassium chlorite: barium chlorite is 1:1:1 by weight ratio; activation The agent uses powdered sodium bisulfate, sodium sulfate and magnesium bisulfate, and the ratio of sodium bisulfate, sodium sulfate and magnesium bisulfate is 1:1:1 by weight; the purpose of the slow-release agent is to control moisture The rate of absorption has the effect of slowly absorbing water. In the actual preparati...

Abstract

The invention discloses slow-release chlorine dioxide sterilizing and purifying powder; the formula of the slow-release chlorine dioxide sterilizing and purifying powder contains the following components in percentage by weight: 5-10% of a chloride dioxide precursor, 12-20% of an activating agent, 5-10% of a slow-release agent, 12-20% of gels, 43-47% of filler and 5-10% of an inert agent. The preparation method of the slow-release chlorine dioxide sterilizing and purifying powder comprises the steps of preparing materials, drying, mixing, etc. The preparation method is quite simple in operating process, and is especially suitable for industrial mass production; the preparation cost is low; the slow-release chlorine dioxide sterilizing and purifying powder can remove use of such air purifiers as formaldehyde and benzene series in air; the sterilizing and purifying powder has a good application prospect in the fields of household environmental protection, health and vaccination, etc., and has such advantages as easiness for storage and long shelf life; and the sterilizing and purifying powder is suitable for being widely popularized and used.

Description

technical field [0001] The invention relates to a slow-release chlorine dioxide disinfection and purification powder and a preparation method thereof, specifically relates to the purification treatment of harmful substances such as formaldehyde in indoor air, and belongs to the field of air purification. Background technique [0002] Formaldehyde, also known as formaldehyde, is a colorless gas with a pungent smell. Its density is slightly higher than that of air. It is easily soluble in water. It is a very volatile organic compound. It is mainly used in various decorative materials, such as wall stickers. Cloth, wall-mounted chemical fibers, carpets, foam plastics, paints and coatings, etc., therefore, are also one of the biggest indoor pollutants that endanger human health. In the modern home environment, excessive concentration of formaldehyde can cause symptoms such as nausea, vomiting, coughing, chest tightness, asthma and even emphysema. The requirements for comfort an...
