Formaldehyde content standard of wood floor:
Generally, the formaldehyde content of wood floors is divided into three grades: E0≤0.5 mg/L, E 1≤ 1.5 mg/L, and E2 ≤ 5.0 mg/L. According to European standards, the formaldehyde content of floors should not exceed 9 mg per 100 g, otherwise it will be judged as unqualified products. According to China's Hygienic Standard for Formaldehyde in Indoor Air, the maximum allowable concentration of formaldehyde in indoor air is 0.08 mg/m3.
How to remove formaldehyde from wooden floor;
1, ventilation to formaldehyde.
Ventilation is the simplest way to reduce indoor formaldehyde content, which makes indoor air convection, thus reducing indoor harmful substances content. Therefore, whether in winter or summer, it is very important to keep indoor ventilation as much as possible.

3. Photocatalytic decomposition to formaldehyde
It is also good to choose photocatalyst to remove formaldehyde. Stimulated by light, the catalyst contained in photocatalyst generates negative ions and hydroxyl radicals with oxygen and water, which can decompose pollutants such as formaldehyde oxide, thus purifying the air.
4, chemical method to formaldehyde
Many people will choose in addition to formaldehyde, an institution in in addition to formaldehyde, and use drugs such as spray. Although this method is effective, it also has shortcomings. First, it is easy to cause secondary pollution and damage furniture. Second, formaldehyde cannot be removed at one time.
