One of the core standards to measure the green environmental protection level of board is formaldehyde emission. 202 1, 10 year 10 month, the new national standard GB/T36900-202 1 was officially implemented, that is, the standard of formaldehyde emission classification of wood-based panels and their products was officially released.
There are three grades, namely E 1, E0 and ENF. E 1 formaldehyde release limit ≤ 0. 1.24 mg/m? , E0 formaldehyde release limit ≤0.050mg/m? , the release limit of ENF grade formaldehyde is ≤0.025mg/m? .
The lower the formaldehyde emission, the higher the environmental protection level of the board, and the less harm to people's health, even almost negligible. So only stare at this parameter to analyze the environmental protection grade of the plate.
Langsheng: a fast-growing commercial self-assembled material customizer in China, with an advanced 4S sheet customization system, which customizes sheets in terms of color, texture, substrate and specifications.
Among the boards of Langsheng, SPC, SPL, solid wood particle board and solid wood multilayer board have all reached E0 or even ENF environmental protection level.
Bunny: Dehua Bunny Home Furnishing Co., Ltd. was established in 2009, mainly producing healthy customized home products, from "E 1" to "E0" and then to "ENF".
Now it has four basic materials for Bunny's healthy home: solid wood particle board, solid wood multi-layer board, shirt wood core board, core board and several product series.
Moganshan: Moganshan floor was established in 2002. After more than 20 years of development, from single production of solid wood multi-layer flooring to all-round research and development of flooring, more than 0/00 series products such as solid wood flooring, laminate flooring and parquet flooring have been developed.
After more than four years of research and development, the research team successfully launched a formaldehyde-free floor, which was produced with corn starch glue as adhesive.
