After the renovation of the new house, the most critical issue is the removal of formaldehyde. Nowadays, there are many kinds of deodorants, odorants, test kits, etc. on the market. Whether it is natural absorption or chemical preparations, people can avoid formaldehyde. So how do you eliminate formaldehyde? How long does it take to renovate a new home?
The release period of formaldehyde is generally 3 to 15 years, which is very serious for the human body, especially infants, pregnant women, the elderly and chronically ill patients. Formaldehyde is mainly found in decorative materials such as siding, ceilings and various types of phenolic resin-based wood-based panels. The wall coverings, wallpapers, paints and coating tubes also contain formaldehyde. Therefore, if furniture, chemical fiber carpets, curtains, sofas, cabinets, etc. are all newly bought, it is important to remove some formaldehyde purification products in advance.
Experts said that after the house is renovated, the indoors will be kept in good ventilation for 3 months, so that the volatile harmful gases will be released as soon as possible, and then they can move into a new home. However, only 80% of the houses that can be accommodated after 3 months, 20% require more time. It is necessary to know that many harmful substances are colorless and odorless, but there is no smell or odor, which does not mean that there is no pollution. For example, the pungent odor of benzene is not large, but it is very harmful to the human body; the radioactive gas is odorless, but it can cause lung cancer.
It is best to carry out indoor formaldehyde testing after renovation. The inspection shall be arranged after the decoration and decoration have been completely completed at least 7 days later. Within 7 days, it is the highest concentration of volatile pollutants. After 7 days, it can basically be reduced to a stable state. This is the best stage of detection. (Xie Hongwei)
