Embodiment 1

[0020] The invention relates to a slow-release chlorine dioxide powder suitable for indoor air purification, which overcomes the complicated manufacturing process of using silica gel as a colloid to make slow-release chlorine dioxide air disinfectants in the prior art, 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.

[0021] 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, 47% Filler, 10% activated carbon composition.

[0022] Make it through the following steps:

[0023] A: Prepare materials, prepare chlorine dioxide precursor, activator, slow-release agent, gel, f...

Embodiment 2

[0033] 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% activated carbon composition.

Abstract

The invention discloses sustained-release chlorine dioxide powder applicable to purifying indoor air. The formula of the sustained-release chlorine dioxide powder mainly comprises the following components in percentage by weight: 5-10 percent of a chlorine dioxide precursor, 12-20 percent of an activating agent, 5-10 percent of a sustained-releasing agent, 12-20 percent of gel, 43-47 percent of packing and 5-10 percent of activated carbon. The sustained-release chlorine dioxide powder can be used as air purifiers to remove formaldehyde, benzene series and the like in the air, and the chlorine dioxide released by the powder can be used for effectively oxidizing the formaldehyde in the indoor air, and no secondary pollutants generate in the oxidizing process, so that the sustained-release chlorine dioxide powder has an excellent application prospect in the fields of household environmental friendliness, healthy epidemic prevention and the like.

Description

technical field [0001] The invention is a slow-release chlorine dioxide powder suitable for indoor air purification, specifically relates to the purification treatment of formaldehyde and other harmful substances 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 and aesthetics are getting higher ...
