The materials used in the renovation will emit some harmful gases. Therefore, the construction must pay attention to window ventilation, but in the rainy season, not only no wind, but also low pressure, humid air, poor ventilation effect, therefore, the problem of air pollution during the rainy season decoration should be caused Pay attention.
Causes more serious indoor environmental pollution
Since the rainy season is characterized by air humidity and low air pressure, indoor air decoration is more likely to cause pollution than other seasons. Why is this? According to the analysis of experts from the China Indoor Decoration Association's Indoor Environmental Testing Center, there are several main reasons:
First, before the onset of the rainy season, the weather is hot and the humidity is increased. At this time, the release of toxic and harmful gases in the decoration materials will increase. According to studies conducted by experts from Japan's indoor environment, when the indoor temperature reaches 30 degrees Celsius, the highest amount of indoor toxic and harmful gases is released.
The second is that in the hot weather, construction workers will emit more pollutants through the respiratory tract, skin, sweat glands, etc. than usual. In addition, in order to protect newly-painted or painted doors, windows, walls, ceilings, etc. from damage by mosquitoes, insects, flies, etc., mosquitoes, insects, and sterilization are also required, which will also cause indoor air pollution. .
Third, during the rainy season decoration, some special decoration processes need to be protected against moisture, moisture and dust. For example, when painting furniture and walls, they need to close the doors and windows, which is more likely to cause a large accumulation of indoor pollutants.
The fourth is that the rainy weather is depressed. Even if all the doors and windows are opened, the normal convection of the indoor and outdoor air will be weakened, resulting in poor indoor ventilation, and it will be difficult for some toxic and harmful gases released from the decoration materials to dissipate as soon as possible.
Indoor air pollution source
1, interior decoration materials
According to spot checks conducted by the Ministry of Health, the Ministry of Construction, and the environmental protection department, 68% of the materials currently contain toxic gas pollution. These materials include paints, plywood, particleboard, and interior wall paints, which contain indoor “invisible killers†that are harmful to the human body. Common organic vapors such as formaldehyde and benzene.
2. Pollution of the building itself
Some properties use concrete antifreeze in winter construction. When the property is put into use, with the increase in temperature and humidity in the summer, another room “invisible killerâ€â€”ammonia—is slowly released from the wall, which can cause excessive ammonia concentration in the indoor environment. , directly endanger human health.
3, the pollution caused by indoor furniture
It is understood that air pollution caused by furniture has become the third largest source of pollution after construction pollution and decoration pollution.
According to experts, formaldehyde and other toxic gases are contained in the adhesives and sheets of furniture. During the construction of the rainy season, due to poor indoor ventilation, air pollution caused by furniture is difficult to purify in time, which will also cause adverse effects on human health.
How to solve the problem of indoor environmental pollution in the rainy season
For this issue, experts from the China Indoor Decoration Association Indoor Environment Monitoring Center made the following suggestions:
First, pay attention to the choice of decoration materials. It is necessary to choose non-toxic and less toxic decorative materials produced by national authoritative departments or brand-name and regular manufacturers;
Second, it is best to ask the formal home improvement company for construction. When signing a decoration contract, it is necessary to propose additional provisions concerning indoor environmental standards, and to submit indoor air quality inspection reports at the time of delivery;
Third, we must do a good job in ventilation and air purification of the renovated room. If there are conditions, ventilate as much as possible. If there is no condition, use indoor ventilation devices and air purification devices that are effective in reducing indoor harmful gases.
4. Pay attention to the labor protection work of workers and residents, especially for painters, wear anti-drug apparatus as far as possible during construction, try not to stay overnight in the paint, if there are headaches, nausea, asthma, sore throat and other symptoms Don't be careless. Ask your doctor for treatment as soon as possible.
Fifth, do a good job in the decoration room interior environment testing and governance.
