What is the indoor formaldehyde detection standard? Is there a national standard? thank you

Only when the formaldehyde content in indoor air is less than or equal to ≤0.08 mg/m3 can you live normally. If it exceeds this standard, even if it is only slightly polluted, it is not suitable for living. Don't take chances. Cases of indoor air pollution abound. Never gamble on the life and health of your family. There are also many methods used by in addition to formaldehyde in daily life. Let's take a look at them with Bian Xiao.

First, Ruishi

It has regular honeycomb voids inside, huge specific surface area, and can adsorb formaldehyde efficiently, with strong adsorption capacity, which can reach more than 20 times that of traditional activated carbon. It not only has large adsorption capacity, but also has ion exchange function, which can decompose harmful substances such as formaldehyde into harmless carbon dioxide and water, and can be used for a long time without replacement. It should be noted that it is an irregular gray ore, not a round particle.

Secondly, activated carbon

Using activated carbon is also a good choice. Activated carbon has abundant pores on the surface, which can absorb indoor odor and has certain effect on pollution control. However, the treatment capacity of activated carbon is limited, and it will be saturated after about half a month of use, so it can't continue to work. In order to achieve the purpose of treatment, it is necessary to constantly replace the new charcoal bag, which invisibly increases the treatment expenditure.

Third, open the window for ventilation.

It is a simple and effective method to open doors and windows to make the air circulate naturally and discharge harmful gases outdoors through airflow. Try to keep indoor windows ventilated for a long time, or use electric fans to accelerate indoor and outdoor air flow, and force ventilation for one month, the decoration taste will be greatly reduced. It is best to put the newly bought furniture in the vent, and the smell is directly excluded from the outdoor.

Four, formaldehyde scavenger

The formaldehyde scavenger reacts with formaldehyde under certain conditions to generate other substances that are harmless to health, thus reducing the indoor formaldehyde concentration. However, it is also a chemical substance, and it may become another indoor pollution source if it is not used properly.

Verb (abbreviation for verb) high temperature

As we all know, formaldehyde will volatilize at high temperature. We can use some heating equipment to raise the temperature in our home a lot, so that a large amount of formaldehyde gas can be volatilized, and then in addition to formaldehyde can be ventilated by opening windows. After repeated operations, most of the formaldehyde in the house can be removed, but we must pay attention to safety when using heating equipment to avoid fire.

All three heads are better than Zhuge Liang, and they are all the same except formaldehyde. It is recommended to combine several methods to make formaldehyde more stable in a safe range.
