Safe removal method of formaldehyde in newly decorated classroom

Abstract

The invention discloses a formaldehyde remover and a safe removal method of formaldehyde pollution in a newly decorated classroom. The formaldehyde remover comprises 20-60 parts of tea extract, 20-60 parts of grape seed extract, 1-5 parts of sodium dodecylsulfate, 1-10 parts of dispersing agent, 0-100 parts of nano negative ion powder, 0-400 parts of water-based polyurethane resin and 958-365 parts of water. The invention also discloses a safe removal method of formaldehyde in a newly decorated classroom. The method comprises the following steps: spraying the specific-formula formaldehyde remover according to the air-wall-desk and chair-carpet-curtain sequence; and after finishing spray, closing the doors and windows, keeping the indoor space closed for 20-40 minutes, and ventilating. After being used for treating the newly decorated classroom, the formaldehyde remover can efficiently remove formaldehyde and remove the peculiar smell pollution, is capable of continuously releasing negative ions beneficial to the human body, effectively lowers the PM2.5 and other pollutants in the classroom, and is safe with no residue.

Description

technical field [0001] The invention relates to a formaldehyde remover for treating source formaldehyde pollution according to the particularity of classrooms, in particular to a method for safely removing formaldehyde in newly decorated classrooms. Background technique [0002] Formaldehyde is a highly toxic substance, and it ranks second on the list of priority control of toxic chemicals in China. Formaldehyde is defined as carcinogenic and teratogenic shape material by the World Health Organization, is the allergen of generally acknowledging, also is one of potential strong mutagen. Studies have shown that formaldehyde has strong carcinogenic and short cancer effects. The lot of documents record, formaldehyde mainly shows aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction to health effects. When its concentration reaches 0.06-0.07mg / m3 in the air, mild asthma will occur in children. When the...

Problems solved by technology

[0008] The ventilation method is to discharge harmful gases to the outside through the flow of air. This is a simple and effective method. The only disadvantage is that the release cycle of formaldehyde is long, which generally takes three to fifteen years. Cannot meet the requirement of removing formaldehyde

However, its disadvantages are that one is passive adsorption, and the other is that once the adsorption is saturated, the pollutants such as formaldehyde adsorbed in it will be released into the air environment again, causing secondary pollution to the environment.

The law of human life is generally outdoors during the day and indoors at night. When people need air purification most, plants cannot play a corresponding role;

[0020] Second, the absorption of harmful substances by plants is extremely limited

The invention claims that it can effectively adsorb and remove formaldehyde and other pollution when used in newly decorated rooms, but it is obviously a passive adsorption, which does not solve the problem of the source of pollution, and cannot increase the negative ion concentration in the room, nor can it reduce PM2. 5 and other dust pollution

[0024] Due to the particularity of the classroom, children are also particularly vulnerable to formaldehyde and PM2.5, and because the classroom is frequently used and the density of children is high, it is often necessary to close the doors and windows to maintain a good teaching environment, which is aggravated The degree of air pollution in the classroom

At the same time, ordinary chemically synthesized formaldehyde scavengers not only have certain toxicity, but also have potential safety hazards, and improper use may cause secondary pollution

The purpose of the present invention is to provide a method for safely removing formaldehyde in a newly decorated classroom, using tea extract and grape seed extract to make a formaldehyde remover, and using a specific spraying method to solve the problem of safely removing formaldehyde and odor in newly decorated classrooms problem
