What are the classifications of particleboard? What exactly does E1 grade E2 particleboard mean?

E1 and E0 standards are divided by European countries according to the free formaldehyde content in wood-based panels, and they are also the standards for the production and use of man-made panels in China's home furnishing industry, namely.

The free formaldehyde content of E1 grade is 9mg 100g

E0 grade formaldehyde content 3mg 100g

Another calculation standard: E1 level, E0

Therefore, the environmental protection standard of the board is not the absence of formaldehyde, but the emission of formaldehyde meets the above standards.

Although the E0 grade board has higher environmental protection standards, its toughness and moisture-proof ability are relatively low because it does not contain green moisture-proof agents and adhesives, and is generally used as a substrate for furniture, but it is not suitable for application in the humid environment of the kitchen.

Grade Marker Limit Scope of Use.

The e0 can be used indoors directly.

The E1 can be used indoors directly.

E2 must be finished and allowed for indoor use.

1. Particleboard, also known as particle board, is a kind of wood-based board made by cutting various branches and buds, small wood, fast-growing wood, sawdust, etc. into pieces of a certain specification, after drying, mixed with rubber, hardener, waterproofing agent, etc., and pressed under a certain temperature and pressure, the particles are unevenly arranged. Although particleboard is also called particle board, it is not the same kind of board as solid wood particle board. Solid wood particle board is only similar to particleboard, but the quality is much higher than particleboard.

2. According to the structure of the particleboard, it is divided into: single-layer structure particleboard; three-layer structure particleboard; particleboard with gradient structure; OSB; waffle particleboard; Molded particleboard.

3. According to the manufacturing method: flat-pressed particleboard; Extruded particleboard. According to the raw materials used: wood particleboard; bagasse particleboard; flax chipboard; cotton straw particleboard; bamboo, particleboard, etc.; cement particleboard; Gypsum particleboard.

Summary. Comparatively, E1 grade plates are better.

Comparatively, E1 grade plates are better.

The main advantages are as follows:

E1 board refers to the environmental protection standard of formaldehyde emission of board is divided into E1, that is, the formaldehyde content per 100g is less than or equal to 15mg, particleboard, MDF, plywood and various wood-based panels use a large number of Zhengpi adhesives, and the adhesives mostly use formaldehyde as the solvent raw material.

The biggest feature of E1 environmental protection board is that the "man-made board" is auspicious and wide, not a pure natural "solid wood", and the board is a standard board made of natural solid wood fiber through glue bonding and other processes, without adding any benzene, formaldehyde and other harmful substances in the production process, so that we can move in immediately after the decoration, so it is preferable to choose the formaldehyde-free board when selecting the board.

The quality of E1 environmental protection board is strictly controlled by layers, its plate surface is smooth and smooth, and the internal and external structure is also blind and even, E1 level environmental protection board type home or household is a full board furniture, and solid wood furniture is mainly logs, or logs as the main frame of grinding, but also with a small number of boards, E1 level board quality is relatively good, but you must choose a regular factory.

Therefore, according to his advantages, we recommend the choice of E1 grade plate for these two types.

First of all, there are points from the thickness, as well as from the amount of formaldehyde released, and there should be varieties to share!
