Many consumers have this kind of question: the building materials they buy are all environmentally friendly products. However, after the end of the renovation, professional institutions have tested the indoor environmental quality and found that the formaldehyde and benzene in the air are exceeding the standard. Why?
The indoor pollutants after renovation mainly come from the building materials and furniture used. The reason why the indoor environment of the building materials is still exceeding the standard is that the building materials are not containing no pollutants but only under certain indicators. Too much use of the standard materials has created the problem of â€œcontamination stackingâ€ of decorative materials. Taking formaldehyde as an example, suppose that in a set of 80 square meters of living room, using 10 environmentally-friendly large core boards, the formaldehyde content in the indoor environment may be in line with national standards, but if 30 large core boards are used in this set of living rooms Then, the indoor formaldehyde content is likely to exceed the standard, causing pollution.
Since there is inevitably a certain degree of material superimposed pollution in the decoration, how to prevent it?
Considering environmental protection in the design process, the concept of â€œenvironmental designâ€ proposed by B&Q is applied, and the problem of material usage is taken into account in the design of the scheme, and the amount of material per unit area is strictly calculated. When the designer measures the house, it will calculate the carrying capacity of the house space, and measure how much the load will cause the harmful substances to exceed the standard. Based on the measurement, the amount of use of various decorative materials is matched. At the same time, when designing, keep a good amount of pre-emptive content for the purchase of furniture and other decorative items. Finally, we must focus on selecting major pollutants such as stone, ceramic tile, paint, and artificial board. We must use brand products that meet national standards.
How can we eliminate the pollution of a renovated house? Here are three economic and practical methods of governance:
Frequently opening windows for ventilation is the easiest and most effective way to remove indoor exhaust. However, since this method does not have much effect on those pollutants that emit slowly, it is impossible to eradicate, but this method is the most basic and necessary.
Activated carbon adsorption
The developed void structure of activated carbon makes it have a large surface area, and it is easy to fully contact with toxic and harmful gases in the air. The strong adsorption field around the activated carbon pores will immediately inhale the toxic gas molecules into the pores, so the activated carbon has a strong adsorption capacity. .
Chlorophytum, aloe vera, and tigertail orchid can absorb a large amount of indoor formaldehyde and other pollutants, eliminating and preventing indoor air pollution.
