Formaldehyde, although it exists all year round, but we all know that the best time to treat it is summer, because the temperature is high in summer, it is easy to volatilize. In particular, the higher the temperature, the more effective; at low temperature, formaldehyde volatility is not strong. So why is formaldehyde pollution more serious in the cold winter? I believe it is a big problem in the hearts of many small partners. Let's get to know about it today!
As we all know, residents living in northern China or cold areas need heating in winter. According to the relevant provisions of the national heating standard indoor air quality standard, the national heating temperature standard is 18 ℃± 2 ℃, i.e. based on 18 ℃, the fluctuation of 2 ℃ between 16 ℃ and 20 ℃ meets the heating standard.
The volatilization point of formaldehyde is 19 ℃. However, this means that the formaldehyde concentration will increase by 0.4 times every time the indoor temperature rises. After heating equipment in winter, people will increase the temperature. Many of them are hidden behind the paint, and formaldehyde will be released from the floor and furniture. The toxicity is more than 10 times higher than normal. We seldom open windows in winter, so a large amount of indoor formaldehyde will be accumulated, which is why some formaldehyde pollution in winter will be more serious 。
According to Xiaobian, many owners have encountered such a problem that the formaldehyde in the inspection room does not exceed the standard in spring and autumn, while the reason for the formaldehyde exceeding standard is found in summer and winter. Especially in winter, when heating starts, not only the pungent smell comes back, but also becomes more serious. Not only is the decoration more serious, but also some uncomfortable symptoms appear on the body, such as dizziness, nausea, eye tingling, cough fatigue and so on.
In fact, the formaldehyde concentration in indoor air is related to the following four factors: indoor temperature, indoor relative humidity, indoor air flow, and the loading degree of indoor materials. This is also why formaldehyde volatilizes, and it will be more terrible in winter, mainly because of the cold weather in winter. No matter when we close the doors and windows, there will be no air flow in the room, and harmful gases such as formaldehyde will stay in the room, which will easily lead to excessive formaldehyde. But people do not know in such an environment, in the long run, it is likely to cause formaldehyde poisoning.
So, how can we avoid formaldehyde in winter?
If you have a budget, you can find a professional formaldehyde company to deal with formaldehyde. This method is fast and effective in the short term. If you don't have a budget, you can ventilate to keep the air in the room circulating. Everyone should form a good habit of frequent ventilation whenever possible, because this is the best way to prevent and treat formaldehyde. The experimental results show that 30% free formaldehyde can be removed by ventilation for more than 6 months.
Through the above introduction, I believe you have a certain understanding of "will formaldehyde pollution be more serious in winter?" I hope the above can help you.
