Formaldehyde hidden dangers in furniture
Do you fully understand the hazards of formaldehyde hidden in furniture? When buying furniture, we can first pull out the drawers and open the cabinet door to experience whether it is so exciting that it makes people cry. If you feel this way, it means that the formaldehyde content of this set of furniture is seriously exceeding the standard. In addition, the furniture made of wood-based panels should be vigilant if it has not been fully edge-sealed. All furniture parts made of wood-based panels should be strictly edge-sealed, especially particleboards for furniture should be required to be fully edge-sealed, which can limit the release of harmful substances in wood-based panels. It should also be noted that due to the use of a large number of low-quality and low-priced materials in some furniture, the price of the furniture is relatively cheap, and the price can easily be bargained for thousands of yuan. Consumers must be careful about this kind of seemingly cheap furniture. You may not see any faults, and you may be happy after using it for a while, and you will realize the truth of “you get what you pay for” after a period of time.
In this environment, people feel stinging eyes and itchy throat as if they are in a closed room sprayed with pesticides. Experiments have shown that when the room temperature rises to 30°C and the indoor relative humidity is 45%, the formaldehyde release concentration in the air is 0.223 mg/m3, which is 2.23 times higher than the national “Indoor Air Quality Standard”; when the room temperature rises to 34 ℃, relative humidity at 50%, the concentration of formaldehyde release exceeds the standard by 5.53 times; and when the room temperature is 18 ℃, relative humidity at 30%, the concentration of formaldehyde in the air is only 0.033 mg/m3, far lower than the national standard.
According to the investigation by the indoor environmental testing agency, in addition to formaldehyde, there are three other indoor pollutants in summer: ammonia pollution caused by the release of concrete antifreeze caused by construction in winter; biological pollution inside the air conditioner, such as “legionella” etc.; Indoor environmental odor pollution, especially the odor pollution produced by chemicals, plastic (16550, 215.00, 1.32%, bar) supplies, toilets and kitchens. Although the above smells may not be harmful to the human body, over time, it will cause symptoms such as vomiting and headache, and even induce various chronic diseases.
Four tips to avoid pollution
In order to avoid indoor formaldehyde pollution in summer, you may wish to take the following methods: open windows for ventilation. Do not rely too much on air conditioners for indoor heatstroke prevention in summer, because most household air conditioners can only adjust the room temperature and have no ventilation function. Windows can be opened when it is cool in the morning and evening to effectively reduce the concentration of indoor pollutants. Families with pregnant women or infants should pay special attention. When the air conditioner is turned on, you can also leave a small gap for the window in the shade. Don’t be afraid of formaldehyde pollution, four secrets to keep you away from formaldehyde pollution
Place some activated charcoal at the source of the pollution. Pollution sources are generally places where man-made panels are used a lot, such as heating hoods, drawers, wardrobes, bookcases, and bed boxes. After putting in the activated carbon, the furniture must be tightly closed, and the released formaldehyde and other harmful gases will be absorbed by the activated carbon to avoid pollution. Put an aquarium indoors. Pollutants such as formaldehyde will dissolve in water, and the aquarium can play a role in reducing indoor pollution. If the concentration of formaldehyde and other pollutants is too high, you can buy an indoor air purifier to treat it. The treatment methods include chemical decomposition, molecular sieve filtration, activated carbon adsorption, negative ion catalysis, etc., and some use sealing wax to seal the furniture surface, so as to achieve inhibition The purpose of releasing harmful gases.
Don’t rush to put the newly bought furniture into the living room. If possible, it is best to put it in an empty room and use it after a while. The newly renovated family has purchased new furniture, it is best not to rush in, so that the harmful gas in the furniture can be released as soon as possible. Pay attention to the quilts placed in the closet in summer, as they will absorb a lot of formaldehyde, so they must be fully aired before use. The fabric sofa should not only pay attention to the fabric, but also pay more attention to the inner filling. The filling material should be solid and evenly elastic. It can rebound quickly after pressing, leaning, squeezing, and releasing pressure, and there is no polluting substance.
