Is the formaldehyde content of plywood high?

1. Compared with other solid wood boards, the formaldehyde content of plywood is still quite high. Because plywood is made of three different layers of wood bark, glue is mainly used in processing, and formaldehyde in glue is an inevitable problem.

2. Formaldehyde release from plywood is generally from both ends, and its release amount is relatively small. Although the qualified plywood products produced by regular manufacturers will cause indoor formaldehyde pollution to a certain extent, the formaldehyde pollution concentration is still within the scope stipulated by national standards, and generally will not exceed the standard, which will not have a great impact on the human body.

3. The formaldehyde emission of plywood varies from 1 year to 15 years according to different processes. Under normal circumstances, formaldehyde in plywood volatilizes quickly in the first 1-3 years, and it will be less in the later period, so if plywood is used for decoration, attention should be paid to maintaining indoor ventilation in the first three years.

4. Even if the plywood is E 1 grade plywood which meets the national environmental protection standards, its formaldehyde emission will increase with the increase of temperature, even exceeding the national formaldehyde concentration standard. Therefore, in hot weather, we should try to avoid sealed air conditioning and keep indoor ventilation. On weekdays, fans, exhaust fans and other electrical appliances can also be turned on to speed up the flow of indoor air.
