Embodiment

[0012] The preparation method of the air purification filter element provided in this embodiment comprises the following steps:

[0013] (1) Get calcium oxide, calcium peroxide, gac, potassium carbonate and deionized water and mix and stir in the ratio of 5:3:3:1:12 to prepare the mixture;

[0014] (2) add tackiness agent and manganese dioxide after stirring, the preparation ratio of tackiness agent, manganese dioxide and mixture is 3:1:4, make purification coating after stirring;

[0015] (3) Mix the de-purification paint and water in a ratio of 1:4 to prepare a purification mixture, intrude the honeycomb board into the purification mixture, soak for 1-2 hours, take it out and dry it naturally, and then cover it with a film after drying. A layer of air filter membrane, and the air purification filter element is made after the film covering is completed. .

[0016] As a preference, the thickness of the Lu-made honeycomb panel is 2cm.

[0017] The invention has the advantage...

Abstract

The invention discloses a method for preparing an air purification filter element, which comprises the following steps: (1) mixing and stirring calcium oxide, calcium peroxide, activated carbon, potassium carbonate and deionized water according to the ratio of 5:3:3:1:12 to prepare Obtain mixture; (2) add tackiness agent and manganese dioxide after stirring, the preparation ratio of tackiness agent, manganese dioxide and mixture is 3:1:4, make purification coating after stirring and mixing; (3) remove purification coating and Water is mixed according to the ratio of 1:4 to prepare the purified mixed solution. The honeycomb board is intruded into the purified mixed solution, soaked for 1-2 hours, taken out to dry naturally, and covered with a film after drying, covered with a layer of air filter membrane, covered with a film After the completion, the air purification filter element is produced. The invention has the advantages of simple structure, reasonable design, small wind resistance, high air purification efficiency and good purification effect.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a method for preparing an air purification filter element. Background technique [0002] At present, indoor air purification technology mainly includes three categories. The first type is physical adsorption through porous materials such as activated carbon, clay, and molecular sieves. However, the amount of adsorption is usually limited, and desorption will be caused when the temperature and humidity change. The second category is to catalyze oxidation by photocatalysis or plasma and negative ion technology. But usually these methods are slow to remove formaldehyde and cannot be completely removed. The third type is to directly oxidize formaldehyde through potassium permanganate, calcium peroxide, etc., so as to achieve the purpose of removing formaldehyde. This type of method usually has a fast reaction rate and a high removal rate. Removal of formalde...
