Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment, the present invention is further described:

[0013] The formaldehyde adsorption board includes an aqueous layer 3, the aqueous layer 3 is soaked with an amino acid aqueous solution, the aqueous layer 3 is wrapped with a porous layer 2, and the porous layer 2 is wrapped with a breathable water-blocking layer 1.

[0014] The above-mentioned formaldehyde adsorption plate, in which the aqueous layer 3 is infiltrated with an amino acid aqueous solution, can be infiltrated into the pores of the porous layer 2, and the polluted air enters the porous layer 2 through the breathable water blocking layer 1 and contacts with the amino acid solution, and the formaldehyde reacts with the amino acid, To achieve the purpose of removing formaldehyde.

[0015] Specifically, the aqueous layer 3 can store and adsorb the amino acid aqueous solution, for example, it can be made of cotton, sponge or the like.

[0016] The aqueou...

Abstract

The invention relates to a formaldehyde absorption board.The formaldehyde absorption board comprises a water-containing layer, wherein the aqueous solution of amino acid infiltrates the water-containing layer, a porous layer wraps the water-containing layer, a breathable waterproof layer wraps the porous layer, the porous layer is made of bentonite or activated carbon, the water-containing layer is made of cotton and sponges, and the aqueous solution of the amino acid is the aqueous solution of one or more of glycine, alanine, valine, leucine, tryptophan, methionine, proline, tyrosine, cysteine amino acid, asparagine, threonine, serine and glutamic acid.The formaldehyde absorption board has the advantages that the aqueous solution of the amino acid infiltrates the water-containing layer, the aqueous solution of the amino acid can outwardly infiltrate to enter the pores of the porous layer and contact with air, and the amino acid reacts with the formaldehyde so as to remove the formaldehyde; the formaldehyde absorption board is of a board shape, the contact area with the air can be increased, and the formaldehyde removing effect is increased.

Description

technical field [0001] The invention relates to a formaldehyde adsorption plate. Background technique [0002] At present, the building materials and furniture used in house decoration often bring formaldehyde pollution. At present, the common method to remove formaldehyde is to set up carbon packs. However, the contact area of ​​carbon packs with air is small, and the adsorption effect is not ideal. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a formaldehyde adsorption plate, which has a larger air contact area and can absorb and remove formaldehyde more quickly. [0004] The technical scheme adopted by the present invention to solve its technical problems is: [0005] The formaldehyde adsorption board comprises an aquifer, the aquifer is soaked with an amino acid aqueous solution, a porous layer is wrapped outside the aquifer, and the porous layer is wrapped with a breathable water-blocking layer; the porous...
