The methanal removing agent consists following elements( by weight percent): amido compound 1- 50 percent, cyanamide compound 0.5-30 percent, hydroxyl group water dissolvable macro molecule compound 0.1-20 percent, nanometer titianum dioxide 0.8-1.5 percent, water 1-30 percent. The invention is of simple operation and effective volatile matter removing performance.
Description
Technical Field
The invention relates to the technical field of eliminating toxic volatile matters in air, in particular to a device capable of eliminating organic toxic volatile matters such as indoor formaldehyde and the like.
Background
At present, when a house and the like are decorated, because the used decoration material inevitably contains harmful substances such as formaldehyde and the like, if the decoration material which does not meet the requirement of environmental protection is used, the material can more release harmful gases such as formaldehyde and the like, a human body can be poisoned after absorbing the gases containing formaldehyde and can seriously endanger the life safety of people, therefore, when a family is decorated and the decorated, the harmful substances containing formaldehyde in the room need to be eliminated so as to ensure that the harmful gases in the room can not exceed the national specified standard, otherwise, the health of people can be influenced, the method for eliminating the harmful air in the room which is usually adopted by people is to utilize a formaldehyde eliminator, the harmful gases containing formaldehyde in the room can be easily eliminated by utilizing the formaldehyde eliminator, for example, one application number is 01133329, the application date is 10-23/2001, the invention relates to a formaldehyde remover, which is an aqueous solution consisting of triethanolamine, sodium metabisulfite, disodium ethylene diamine tetraacetate, 2, 3, 4, 5, 6-pentahydroxyhexanal and distilled water, wherein the dosage of the triethanolamine, the sodium metabisulfite, the disodium ethylene diamine tetraacetate, the 2, 3, 4, 5, 6-pentahydroxyhexanal and the distilled water is respectively 0.9 to 1.1 part, 0.22 to 0.28 part, 0.2 to 0.6 part and 125 parts (by weight) to prepare a concentrated solution, and the concentrated solution is diluted to 1000 parts (by weight) by the distilled water before application. The method for eliminating formaldehyde by using the formaldehyde eliminating agent is to spray in a room, but because the volatilization of formaldehyde in the indoor furniture is a slow process and the spraying is a short-time process, the formaldehyde can be effectively eliminated by continuously spraying, otherwise, the elimination effect is influenced. The above method is troublesome to operate and has unsatisfactory effect.
Disclosure of Invention
The invention aims to solve the defects and provide paper or cloth which is simple to use and operate and has good effect of eliminating toxic volatile matters such as formaldehyde and the like.
The technical solution adopted by the present invention to solve the above technical problems is as follows:
paper or cloth for eliminating formaldehyde and indoor volatile organic matter is made up of paper or cloth as carrier through adsorbing formaldehyde eliminating solvent onto the paper or cloth and drying.
The formaldehyde elimination solvent is prepared by mixing and blending the following components in percentage by weight:
1 to 50 percent of amino compound and 0.5 to 30 percent of cyanamide compound
0.1-20% of water-soluble macromolecular compound containing hydroxyl
0.8 to 1.5 percent of nano titanium dioxide and 1 to 30 percent of water
The amine-based compound is urea. The water-soluble macromolecular compound containing hydroxyl is carboxymethyl cellulose CMC.
The cyanamide compound is dicyandiamide.
The invention adopts the technical proposal to achieve the following beneficial effects: because the paper or cloth material is used as the carrier, when the material is stored indoors, harmful substances such as formaldehyde and the like can be naturally absorbed without frequent spray treatment; the utilization rate is high, and meanwhile, when a certain amount of the absorbent is absorbed, the color of the paper or cloth material can be changed, so that people can be reminded to replace a new absorbent in time, and the operation is simple and convenient; the method overcomes the problems of the methods of eliminating formaldehyde by spraying and the like adopted by people for a long time, and the elimination rate of formaldehyde and the like reaches more than 90 percent through experimental tests, thereby being an ideal effective method for eliminating formaldehyde pollutants in the air at present.
Detailed Description
The paper or cloth of the invention is prepared by the following components (weight percentage) of formaldehyde eliminating agent:
the amino compound is urea 45%, and the cyanamide compound is dicyandiamide 15%
Carboxymethyl cellulose CMC 8.5%
Nano titanium dioxide 1.5% and water 30%
Then adsorbing the solvent on paper, and drying.
The principle of eliminating toxic volatile matters such as formaldehyde and the like by the paper or the cloth is as follows: the chemical equation for the reaction of an amine-based compound with formaldehyde is:
chemical equation of reaction of cyanamide compound and formaldehyde:
TIO2the mechanism of photocatalytic action of (a):
TIO when photons with a wavelength of less than 387.5nm are irradiated2After the surface, in the valence bandElectrons are excited to the conduction band to generate highly active photogenerated holes (h) in the valence and conduction bands, respectively+) And e-(4-7)：
Under different conditions, h+And e-Hydroxyl radicals (+ OH) are produced through a series of reactions.
At high pH, + OH readily passes OH-Direct migration to photoactive TIO2A surface, trapping the cavity to generate:
at low pH, + OH readily passes OH-With adsorbed O2 -Series (O)-、O2 -、O2 2-、O3 -) Is combined to form H2O2Further generating:
in addition to this, the present invention is,h generated+Can also be directly adsorbed on the TIO2Surface water is oxidized to + OH:
the + OH generated by the above reaction can oxidize adjacent organic pollutants, and can diffuse into liquid phase to oxidize organic pollutants, and in addition, many organic pollutants can be directly absorbed by the reaction vessel+And (4) oxidizing.
The nanometer titanium dioxide in the product can effectively eliminate other volatile organic compounds, thereby realizing the purification of indoor toxic gas.
