Abstract

The invention provides a formaldehyde removal agent, and relates to the field of air purification. The formaldehyde removal agent disclosed by the invention adopts a composite formula and contains various effective formaldehyde removal components, such as a biological decomposition enzyme, an organic matter A and a photocatalyst, wherein the organic matter A is organic acid or organic alkali. The formaldehyde removal agent not only can be used in a spray form, but also can be loaded on a nano material, filter cloth or filter paper and other formed objects so as to be used, has better stability, and is convenient to store and use; the formaldehyde removal agent has a good aldehyde removal effect even in a closed space or a space with weak light; the formaldehyde removal agent can quickly, efficiently and irreversibly remove aldehyde harmful gases harmful to human bodies in a living space at room temperature through reasonable adjustment of the raw materials and the ratio and the synergistic effect of the effective components, does not cause secondary pollution, and has the advantages of environmental protection and no toxicity.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an aldehyde remover capable of quickly, efficiently and irreversibly removing aldehyde harmful gases. Background technique [0002] Formaldehyde is a highly reactive substance and has been used in building materials and furniture since ancient times as a hardening agent for phenolic and melamine-based adhesives. On the other hand, formaldehyde is highly irritating and cytotoxic, so it is desired to be decomposed and removed as an environmental pollutant. Especially in the indoor environment, as one of the causes of residential syndrome, more and more attention has been paid to it. The national standard "Code for Control of Indoor Environmental Pollution in Civil Construction Engineering" GB50325-2020 has set 0.08mg / m 3 The following indoor environment pointer values. [0003] To remove gaseous formaldehyde released from houses, furniture, etc. into the living space, th...
