How to know whether the smell in the furniture is formaldehyde and how to identify

When the indoor content is 0 1 mg m3, there is peculiar smell and discomfort; 0 5 mg m3 can irritate the eyes and cause tearing; 0 6 mg m3 causes throat discomfort or pain; Higher concentrations can cause nausea, vomiting, coughing, chest tightness, wheezing and even emphysema; When 30 mg m3 is reached in air, it can cause immediate death.

The concentration of formaldehyde in indoor air is related to the following four factors: 1 indoor temperature, 2 indoor relative humidity, 3 indoor material loading degree (i.e., the surface area of formaldehyde emitting materials per cubic meter of indoor space), 4 indoor air exchange (i.e., indoor air circulation). Under the conditions of high temperature, high humidity, negative pressure and high load, the intensity of emission will be exacerbated.

The measured data show that under certain conditions, the concentration of formaldehyde in the air in the small environment of the living room can be gathered above the standard allowable level, and the release period is relatively long, the study of Yokohama National University in Japan shows that the release period of indoor formaldehyde is 3-15 years.

How to reduce indoor formaldehyde concentration.

1. Try to use interior decoration and decoration materials with low formaldehyde content and formaldehyde-free content, which is the foundation for reducing formaldehyde content in indoor air. During construction, the paint and coating for surface decoration are fully cured to form a stable layer that inhibits formaldehyde emissions.

2 When buying furniture, you should choose products with less pungent odor, because the greater the pungent odor, the higher the formaldehyde release. At the same time, it is necessary to check whether the particleboard used for furniture is fully edge-banded. Families with conditions can leave the newly purchased furniture vacant for a period of time before reuse.

3 Keep indoor air circulation. This is an effective way to remove indoor formaldehyde, you can choose an effective air ventilation device, or open the window for ventilation when the outdoor air is good, which is conducive to the formaldehyde emission and discharge of indoor materials.

4. The renovated room should not be moved in immediately, but should have a certain amount of time to let the formaldehyde in the material be emitted with a higher force.

5. Reasonably control and regulate the indoor temperature and relative humidity, formaldehyde is a slow volatile substance, with the increase of temperature, volatilization will be faster.

6 Hanging flowers and plants indoors is beneficial. It will reduce the concentration of harmful gases in the room, so you may wish to give it a try.

7. If the indoor formaldehyde content is relatively high, you can ask the indoor environment testing experts to test it, so as to understand the degree of formaldehyde exceeding the standard in the indoor air, so as to take corresponding treatment measures. The indoor environmental testing center has some measures and treatment methods to reduce indoor formaldehyde, which can be selected according to the degree of indoor air pollution.

The only correct way to identify is to entrust a testing agency with CMA certification to test, otherwise, it will not only cost unjust money, but also cause endless trouble. Recently, a report in the "Labor Daily" "Bluffing people to promote products and false detection" is very good, and it is recommended to take a look.

Formaldehyde content. Manual identification is mainly determined by smelling whether it is pungent or not.

The cheapest and most effective solution is to put more spider plants. The results are superb.

As long as your nose doesn't smell right, it's possible.
