Bamboo and wood fiber wallboard does contain a certain amount of formaldehyde, but the formaldehyde content is usually low and far below the national standard, so it is regarded as an environmentally friendly material. The following is a detailed answer to the formaldehyde problem of bamboo and wood fiber wallboard:
First, bamboo and wood fiber wallboard formaldehyde sources
Bamboo and wood fiber wallboard itself is made of sawdust, wood chips, bamboo chips and other low plant biomass fiber, these raw materials themselves do not contain formaldehyde. However, in the process of plate making, adhesives such as glue are usually used in order to enhance the strength and stability of the plate. These adhesives may contain formaldehyde, resulting in bamboo and wood fiber wallboards with a certain amount of formaldehyde in the finished product.
Second, formaldehyde content of bamboo and wood fiber wallboard
Although formaldehyde-containing adhesives may be used in the process of making bamboo and wood fiber wallboards, the formaldehyde content of qualified bamboo and wood fiber wallboards is usually very low. Specifically, the amount of formaldehyde released is usually around 0.2 mg per liter to 0.3 mg per liter, far below the national standard of 1.5 mg per liter. At the same time, some high-quality bamboo and wood fiber wallboards can even meet the EO level environmental standards, that is, the formaldehyde content is less than or equal to 0.5 mg per liter (national standard), or even lower to 0.1 mg per liter, which is less than the formaldehyde content of some vegetables and fruits.
Third, bamboo and wood fiber wallboard formaldehyde treatment
It is worth noting that the bamboo fiber inside the bamboo fiber wallboard has a special ultra-fine pore structure, which makes it have a strong adsorption capacity. This structure can absorb harmful substances such as formaldehyde and toluene in the air, thereby reducing indoor formaldehyde concentration to a certain extent and improving indoor air quality.
Four, purchase advice
When buying bamboo and wood fiber wallboard, consumers should pay attention to the following points to ensure that they buy products with low formaldehyde content and good environmental performance:
Check whether the product has relevant environmental certification and testing report, such as EO-level environmental standard certification.
Observe whether there are black particles in the cut of the product to determine whether it has used inferior raw materials or adhesives.
The quality of the product is judged by measuring its weight and soaking test. In general, too heavy products may have more calcium powder, and too light products may foam seriously. In the water immersion experiment, the product of the new material will slowly float or suspend in the water, while the product of the added material or the full material will have a different rising or sinking speed.
In summary, although bamboo and wood fiber wallboard may contain a certain amount of formaldehyde in the process of board making, the formaldehyde content of qualified bamboo and wood fiber wallboard is usually very low, and far below the national standard. At the same time, the bamboo fiber inside it also has the ability to absorb harmful substances such as formaldehyde, so it can be considered as a decorative material with good environmental protection performance. When purchasing, consumers should pay attention to the environmental protection certification and testing report of the product to ensure the purchase of reliable quality products.
