Whether it's new house decoration or new furniture, formaldehyde is released, and the harm can induce tumor or cancer, which makes many people pay attention to prevention. So how to detect whether indoor formaldehyde exceeds the standard? Excessive formaldehyde will induce a series of diseases, so we must pay attention to it.
What to do if formaldehyde exceeds the standard
Ventilate regularly to prevent formaldehyde from gathering indoors
In autumn and winter, because the outdoor temperature is very low (especially in the North), indoor air conditioning and heating, many people rarely open windows for ventilation, even if the house has just been decorated, this is very harmful. Not often ventilated, indoor formaldehyde will accumulate in a limited space, formaldehyde concentration will rise quickly. And such air is inhaled by human body for a long time, it will cause damage to our body, and may cause cancer seriously.
Therefore, the autumn decoration should pay attention to frequent ventilation. Experts suggest that when decorating, we should take advantage of the strong autumn wind and always keep the ventilation. We can open the windows in the morning and evening to improve the indoor air quality. In addition, if the furniture is made at home, the on-site operation of paint and wood products should be reduced, and auxiliary materials such as paint, coating and adhesive should also be well-known brands.
Pay attention to putting some formaldehyde absorbing plants indoors
Some green plants with strong formaldehyde absorption can also be placed in the room, such as Chlorophytum, Huwei orchid, aloe, ivy, Agave, etc., which can release oxygen, absorb formaldehyde and other harmful substances, and also play a certain role in regulating the indoor dry and wet environment. You can also use humidifier and air freshener to adjust the air quality indoors.
Pay attention to environmental protection furniture
The best way to prevent formaldehyde from exceeding the standard of furniture bought at home or made to order is to go to a well-known manufacturer to make furniture to order. For example, if you make your own wardrobe, you'd better go to a large overall wardrobe manufacturer. The quality is generally guaranteed, and the products are also very environmentally friendly, so you don't need to worry about formaldehyde exceeding the standard.
Simple and generous decoration, avoid using too many chemical materials
Indoor formaldehyde exceeds the standard mainly because the raw materials used for decoration and some unqualified furniture contain a large amount of formaldehyde, and formaldehyde can be completely distributed for a long time. No matter how much environmental protection furniture has more or less formaldehyde, so if you want to reduce the formaldehyde content, it is not necessary to decorate too complex, simple and generous.
Indoor ventilation after decoration
We all know that after the interior decoration, it will take some time to move in. The reason is to let formaldehyde emission. During this period, try to keep indoor air circulation and open windows for ventilation.
How to detect whether indoor formaldehyde exceeds the standard
1. Self experience method
This is a relatively rough detection method, but it can not estimate the concentration of this kind of harmful gas in detail. It can be mainly carried out from the following aspects: for example, after moving into a new home, the disease rate of family members becomes higher, the resistance of family members becomes worse, and there is a sharp smell when they are near the wall or furniture. In this way, they can basically feel that the formaldehyde in the home exceeds the standard.
2. Physiological response of animals and plants
This is also a relatively rough test method. For example, when entering a newly installed house, the small animals raised in the home suddenly often do not eat, and they are lazy without previous liveliness, immunity decline, etc., and the plants in the home begin to wither and die slowly, which can be regarded as the harm of indoor formaldehyde.
3. Formaldehyde self test box
This is a relatively simple test method. Before the professionals come to the door for testing, they can buy their own self-test box for testing. If they find that formaldehyde exceeds the standard, they can ask the indoor environmental protection company for testing. The self-test box is similar to the pH test paper. We can roughly estimate whether formaldehyde exceeds the standard according to the color comparison.
4. Ask professional indoor environmental protection company to test
This is one of the most effective ways to test the concentration. Because this kind of hazardous gas is invisible, if you can't know the concentration of formaldehyde by any means, the professional indoor inspection company will test the specific concentration of formaldehyde on the spot through professional testing tools and equipment.
