The new national standard is applicable to all kinds of indoor wood-based panels and their products, such as fiberboard, particleboard, plywood, joinery board, recombined decorative materials, laminated veneer lumber, laminated veneer lumber, wood-based panels, wood wallboard and wooden doors. It is clearly defined that the formaldehyde emission of indoor wood-based panels and their products is divided into three levels according to the limited value, namely, E 1 level, E0 level and ENF level:
E 1 grade ≤0. 124mg/m? ;
E0 grade ≤0.050mg/m? ;
ENF grade ≤0.025mg/m? ; ENF standard allows formaldehyde to exist in the plate, but it cannot exceed 0.025mg/m? This is the highest limit; The lower limit is the highest aldehyde content of the board itself.
The new national standard is an encouragement to enterprises that always adhere to the R&D environmental protection concept (note: the ENF level of the new national standard is the aldehyde-free level of the original enterprise standard).
Combined with the new requirements of the market for quality and healthy life, the original wood board 1 has been comprehensively upgraded in terms of core materials, environmental protection grade, intelligent manufacturing technology, product stability and applicability. Once again, lead the market with excellent performance and quality, and bring consumers a brand-new healthy value experience. Using rotary cutting log chips and log processing fine materials as base materials, the logs are finely decomposed and fully pressed and combined, almost no waste is produced, and the utilization rate of wood can reach over 99%. Products with high environmental protection utilization rate are strongly advocated by the industry. It is a real environmental protection product with high utilization rate and brings remarkable economic value to social development.
The original board 1 uses subtropical evergreen trees, which are called "safe trees" and contain no toxic substances. The moisture content of wood is less than or equal to 8%, the coefficient of shrinkage and expansion is small, the density is moderate, and the properties of wood are more stable than other wood. The tree species grows in an environment with sufficient rainfall and light, and has strong structure, good corrosion resistance, flexible texture and strong deformation stability.
The original board 1 follows the Classification Standard of Formaldehyde Emission from Wood-based Panels and Their Products (GB 39600-202 1), and the formaldehyde emission is as low as 0.0 15mg/m, which meets the Enf standard. After high temperature drying and hot pressing, the products can effectively eliminate parasites and fungi in wood, stay away from formaldehyde from the source, and help the health and safety level of home improvement to a new level.
Using aldehyde-free MDI glue widely requisitioned in people's livelihood, medical care and other fields, the health grade is better than natural raw materials. Layer-by-layer planer and MDI are bonded and solidified into a whole, with precise and compact structure and strong water resistance, which has become a new type of environmental protection material with high utilization rate.
