preparation example Construction

[0042] The present invention also provides a method for preparing the formaldehyde-removing filter screen described in the above technical solution, comprising the following steps:

[0043] a) impregnating the small carrier with a guanine solution, and then drying to obtain a small carrier loaded with a guanine active ingredient;

[0044] b) immobilizing the small carrier loaded with the guanine active ingredient on a porous large carrier to obtain a formaldehyde purification layer;

[0045] c) Fixing primary effect mesh cloth layers on both sides of the formaldehyde purification layer to obtain a formaldehyde removal filter.

[0046] Wherein, the types, characteristics and sources of the guanine, the small carrier, the porous large carrier and the primary effect mesh layer are all consistent with those described in the above technical solution, and will not be repeated here.

[0047] According to the present invention, the small carrier is impregnated with the guanine soluti...

Abstract

The invention provides a formaldehyde degradation filter screen, a preparation method thereof and a purifier. The formaldehyde degradation filter screen provided by the invention comprises a first initial-effect screen cloth layer, a formaldehyde purification layer and a second initial-effect screen cloth layer which are in contact in sequence; the formaldehyde purification layer comprises a smallcarrier carrying guanine active components and a porous large carrier fixing the small carrier, and the small carrier is fixed on the mesh surface of the porous large carrier. The formaldehyde degradation filter screen provided by the invention is safe and environment-friendly, low in cost, and capable of effectively degrading formaldehyde.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a filter screen for removing formaldehyde, a preparation method thereof and a purifier. Background technique [0002] Formaldehyde is a substance that is extremely harmful to the human body. In house decoration, furniture, wall paint, wallpaper and other materials may release formaldehyde, which is harmful to human health. Therefore, how to effectively remove formaldehyde has always been the focus of attention. [0003] At present, there are formaldehyde removal devices such as formaldehyde removal purification filters or purifiers on the market. The existing formaldehyde removal purification filters mostly use catalysts or activated carbon / silicon dioxide loaded with reactants to achieve the purpose of formaldehyde removal. However, the catalyst production process is not environmentally friendly, the cost is high, and it requires a certain amount of energy to function;...
