Is formaldehyde 04 serious?

With the improvement of people's living standards, people now have more and more material needs. In order to make the living environment more comfortable, people will buy new houses in some places with more beautiful environments. The decoration of new houses has always been a headache for everyone, because after the decoration, a lot of harmful gases will be produced, especially formaldehyde, which is more harmful to the human body, so it must be removed. So is formaldehyde 04 serious?

First, is formaldehyde 04 serious? 04 refers to 0.4ppm, which is 5 times higher than the standard. The national standard stipulates that a new house can only be occupied when the formaldehyde concentration is lower than 0.08ppm. If it is 0.4, there will be a noticeable odor, discomfort, and a sore eye.

Second, since the formaldehyde release cycle is relatively long, 3 to 15 years, especially in the high temperature of summer, furniture will also release a large amount of formaldehyde, so it is urgent to solve the formaldehyde problem in new houses. Formaldehyde concentration value: above 0.5mg/m3 is considered to be seriously exceeded. Formaldehyde is a gas with a strong pungent odor and is easily soluble in water. Its 40% aqueous solution is called formalin. The impact of formaldehyde on human health is mainly manifested in olfactory stimulation, allergies, abnormal lung function, abnormal liver function and abnormal immune function. Long-term exposure to low doses of formaldehyde can cause chronic respiratory diseases, nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, and genetic mutations in the cell nucleus. Suggestions: Plants have a strong ability to absorb formaldehyde, such as cactus, spider plant, aloe, Clivia, cycad, chrysanthemum, etc. Folk remedy: put tea dregs, grapefruit peels, onion slices, pineapple chunks, etc. in the newly renovated room or fumigate the entire room with white vinegar. Using tea leaves, grapefruit peels, onion slices, pineapple chunks and other folk methods can actually only play a covering role, such as covering up the odor in the toilet. But these things don't absorb formaldehyde in the air.

Is formaldehyde 04 serious? It is very serious. Open windows for ventilation: After decoration, you must open windows for ventilation. No matter what you use to remove formaldehyde, you still need to keep ventilation. This is the most effective. If you are worried that opening the windows alone will not be enough to dissipate all the formaldehyde, you can use other methods in combination. Chemical method: There are many formaldehyde removers on the market, but these formaldehyde removers are made of all kinds of raw materials and grades. Many of them are inferior raw materials that will cause clean pollution. It is recommended that you be careful when choosing. Physical adsorption method: Use some Maya blue or activated carbon. These materials are good formaldehyde adsorbents. There are many tiny pores in their materials, so they can absorb a lot of formaldehyde. The effect of activated carbon will be much worse, but it is cheaper.
