Abstract

The invention discloses a novel efficient formaldehyde catalyzing material and a digital display formaldehyde purifier prepared from the same. The novel efficient formaldehyde catalyzing material comprises a carrier and a formaldehyde catalyzing coating coated on the carrier, the carrier comprises a non-woven fabric layer and a composite fabric layer which are fixed together, and the formaldehydecatalyzing coating is prepared from the following raw materials: high-porosity manganese oxide fiber microspheres, methylglycine proline, an adhesive, nano titanium dioxide, permanganate, distilled water, a defoaming agent and a dispersing agent. The preparation method of the high-porosity manganese oxide fiber microspheres comprises the following steps of: twisting and gathering manganese oxide fiber membranes with a width of 1.5m and disorderly distributed internal fibers to form manganese oxide fiber bundle strips, then performing cutting off and extrusion to form the porous structure nanofiber microspheres. Due to the fact that a large number of micropores exist in the surfaces and the interiors of the high-porosity manganese oxide fiber microspheres in the coating, the efficient formaldehyde catalyzing material can rapidly adsorb formaldehyde in the air and undergo catalytic decomposition, and the formaldehyde removing rate is high.

Description

technical field [0001] The invention relates to the technical field of formaldehyde catalytic materials, in particular to a novel high-efficiency catalytic formaldehyde material and a digital display formaldehyde purifier prepared therefrom. Background technique [0002] Formaldehyde, also known as formaldehyde. It is a colorless gas with a special irritating odor, which is irritating to human eyes and nose. The main hazard of formaldehyde is the irritation to the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable, greater than 0.08m 3 High formaldehyde concentration can cause eye redness, itching, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc. Newly renovated rooms have high formaldehyde content, which is the main cause of many diseases. Long-term exposure to formaldehyde increases the risk of developing special cancers such as Hodgkin's lymphoma, multiple myelo...
