Problems solved by technology

The method of using the above-mentioned formaldehyde remover to eliminate formaldehyde is to spray indoors, but since the volatilization of formaldehyde in indoor furniture is a slow process, and spraying is a short-term process, it needs to be sprayed continuously to effectively eliminate, otherwise it will affect Eliminate the effect
The above method is cumbersome to operate and the effect is not ideal

Embodiment Construction

[0013] Paper or cloth of the present invention is to prepare solvent with the following components (percentage by weight) of the following formaldehyde scavenger:

[0014] Amino compounds such as urea 45% Cyanamide compounds such as dicyandiamide 15%

[0015] Carboxymethylcellulose CMC 8.5%

[0016] Nano Titanium Dioxide 1.5% Water 30%

[0017] Then the above solvent is adsorbed on the paper, and it is made to dry.

[0018] The paper or cloth of the present invention eliminates the principle of toxic volatiles such as formaldehyde: the chemical equation of the reaction between the amino compound and formaldehyde is:

[0019]

[0020] The chemical equation for the reaction of cyanamide compounds with formaldehyde:

[0021]

[0022] TIO 2 Mechanism of photocatalytic action:

[0023] When photons with a wavelength less than 387.5nm irradiate the TIO 2 After the surface, the electrons in the valence band will be excited to the conduction band, thereby generating hi...

Abstract

The invention discloses a paper or cloth which removes methanal and indoor organic volatile matter which features that it is base on paper or cloth material, absorb methanal removing agent on paper or cloth and dry the basal material to get product. 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 [0001] The invention relates to the technical field for eliminating air toxic volatiles, and more specifically relates to an object capable of eliminating indoor formaldehyde and other organic toxic volatiles. Background technique [0002] At present, when decorating houses, etc., because the decoration materials used inevitably contain harmful substances such as formaldehyde, if the decoration materials that do not meet the environmental protection requirements are used, the materials will release more harmful gases such as formaldehyde, which will harm the human body. After absorbing this gas containing formaldehyde, it will be poisoned, and in severe cases, it will endanger people's life safety. Therefore, during and after the decoration of the family, it is necessary to eliminate the harmful substances containing formaldehyde in the room to ensure indoor safety. Harmful gases cannot exceed the national standard, otherwise it will affect people's health. T...
