Sustained-release chlorine dioxide powder applicable to purifying indoor air

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 ...
