Home decoration will produce serious indoor air pollution, among which formaldehyde is the most harmful to human health. If formaldehyde pollution cannot be removed in time, it will become a major hidden danger to the health of the family. So what are the hazards caused by not removing formaldehyde promptly and correctly after decoration, and what is the most effective way to remove formaldehyde?
Five major hazards of improper formaldehyde removal after decoration
Mucous membrane irritation: The most obvious harm of formaldehyde is the irritation to the skin and mucous membranes. When formaldehyde exceeds a certain concentration, it can cause redness and swelling of the eyes, sore throat, respiratory tract pain, and redness of the eyes. Inflammation, chest tightness, asthma, dermatitis and other symptoms.
Damage to the brains of children: Formaldehyde may affect or even damage the brains of children and adolescents who are in the growth and development period, leading to serious consequences such as mental retardation, inattention, and memory loss that are irreparable.
Acute poisoning reaction: When the concentration seriously exceeds the standard, the symptoms of acute formaldehyde poisoning will include burning pain in the throat, difficulty breathing, pulmonary edema, allergic purpura, allergic dermatitis, elevated transaminase and other symptoms.
Decreased immunity: The elderly, teenagers and children with weak constitutions are very sensitive to formaldehyde. Experimental data shows that children who live in formaldehyde-polluted environments for a long time are more likely to catch a cold in winter than children in healthy environments. It can be seen that formaldehyde has a greater impact on human immunity. direct impact.
Carcinogen: Formaldehyde has been identified by the World Health Organization as a carcinogen and deformity substance. It is a recognized source of allergy and one of the potential strong mutagens. Formaldehyde ranks second on my country's priority list of toxic chemicals.
What is the most effective way to remove formaldehyde?
Ventilation method. Ventilation is required for more than half a year after decoration before moving in. Ventilation can remove most of the indoor air pollution, which is environmentally friendly and saves money. However, the ventilation method also has its limitations because there are many dead corners in the room where the air does not circulate. The formaldehyde concentration here is often the highest, so the ventilation method can only remove % to % of the pollutants.
Physical adsorption method. The physical adsorption method uses porous materials such as activated carbon and Maya blue to adsorb organic pollutants. Among them, activated carbon has the advantages of low price and wide application range. The disadvantage is that it can only absorb but not adsorb pollutants. When the activated carbon is saturated, the pollutants will evaporate back into the indoor air. Therefore, activated carbon bags need to be replaced every month to avoid secondary pollution. Compared with activated carbon, Maya blue has weak electricity that can not only absorb pollution molecules but also lock them to prevent formaldehyde from evaporating into the air again causing secondary pollution. The photocatalyst contained in the component can decompose pollutants into harmless substances under light, so it is used Maya Blue is best dried monthly but does not need to be replaced. However, the disadvantage of Maya blue is that the cost is too high and the price is often higher than that of activated carbon, so it has not been widely used. At the same time, it should be noted that when purchasing physical adsorption materials, products with vacuum packaging should be selected.
Chemical decomposition method. The commonly used material for formaldehyde removal by chemical decomposition is photocatalyst. Photocatalyst can decompose harmful organic matter in the air under light conditions and generate harmless gases such as water and carbon dioxide to achieve the purpose of controlling pollution. Photocatalysts have the advantage of being safe and harmless without secondary pollution. However, photocatalysts can only react under strong light irradiation, so the effect is not ideal when used indoors. Therefore, photocatalysts are often used as a component of Maya Blue to combine formaldehyde removal to achieve the desired results. Better governance results.
