Formaldehyde is a very common chemical in the life that is very harmful to the human body. It is especially concentrated in the newly renovated new house, and the formaldehyde release period is long, and it can not be completely removed in a short time, which is extremely harmful to the human body. Then, after the renovation of the new house, how long does it take to stay in the air? How can we accelerate the release of formaldehyde? Next, we will analyze it in detail.
Key point 1: The degree of pollution in the home - how much formaldehyde exceeds the standard.
After the decoration, the formaldehyde in the home is over-standard, and the time required for ventilation must be prolonged. Generally, the mild pollution ventilation can be basically 3 months-6 months.
Key point 2: Specific pollution situation - the density of furniture, ventilation is good.
If the density of furniture is large, ventilation is definitely not complete. If the ventilation conditions are not good, it will affect the efficiency of ventilation. Therefore, if the ventilation is not good, it is usually extended for more than 3 months.
Key point 3: There are no elderly, pregnant women, infants and young children in the family.
People with poor physical fitness have poor resistance and have higher requirements for indoor formaldehyde concentration. Therefore, it is best to ventilate for 2 or 3 months after reaching the standard.
In general, it takes more than half a year, but if there are people with poor ventilation, high pollution, or poor physical fitness, it is necessary to extend the ventilation cycle according to the specific circumstances.
In addition to ventilation, there are many ways to use formaldehyde in indoors. Xiaobian has selected several simple and convenient methods:
Method 1: Ventilation Method Ventilation is a traditional method of removing formaldehyde. It works quickly. When the wind speed is high enough, the formaldehyde can reach the standard in a few minutes, but the effect is not lasting, and the window is useless. Moreover, the decoration materials used in new houses are more and more serious, and the pollution is more serious than the original one. It is slower to remove aldehydes by ventilation alone, so it is recommended to use them together with other methods of removing formaldehyde.
Method 2: Activated carbon Activated carbon is a relatively primitive adsorbent material, and its formaldehyde adsorption amount is relatively low. However, activated carbon is easy to adsorb and saturate. After saturation, it must be replaced with new ones, otherwise it will cause formaldehyde to rebound. It is generally recommended to change it from 20 days to 1 month, and it is best to replace the new house in the first year if it is replaced more than 10 times.
Method 3: Luoting Stone Luoting Stone was originally one of the purification raw materials for large-scale air purification equipment. In recent years, it has gradually become one of the mainstream methods for household formaldehyde removal. It not only has a large amount of formaldehyde adsorption, but also completely decomposes formaldehyde, so it will not be saturated. It can be used for more than 3 years in one time, and it does not need to be replaced, which is suitable for the long-term release of formaldehyde.
Method 4: In addition to formaldehyde plants Some plants also have certain functions in addition to formaldehyde, such as spider plant and green radish, etc., but Xiao Bian reminds that plants only help to remove aldehydes, and must not be used as the main means of removing formaldehyde.
