Is the joinery board environmentally friendly?
Only E 1 blockboard can be used for home decoration. If the product is E2-grade joinery board, even if it is qualified, its formaldehyde content may be more than 3 times that of E 1 grade joinery board, so it must not be used for home decoration. Third, the unfinished joinery board, especially the renovated backboard, all kinds of cabinet inner panels and heating covers, should be purified and sealed. Experts have developed formaldehyde sealant, formaldehyde sealing wax and aerosol to eliminate and seal formaldehyde, which have the best effect when used in decoration. However, if the dosage of E 1 grade large core board is too large, it may also cause the overall indoor formaldehyde content to exceed the standard, so even if it meets the standard, it may not be absolutely harmless to the human body.
General 100 square meters room, using no more than 20 blockboards. At the same time, other interior decoration should be considered. If you use too much, the formaldehyde in the indoor environment will exceed the standard. In particular, don't use joinery board as the lining under the floor, so as not to cause formaldehyde in the indoor air to exceed the standard seriously.
Advantages and disadvantages of joinery board
Advantages of joinery board
1. Compared with particleboard and medium density fiberboard, the natural wood characteristics of blockboard are more in line with human requirements for natural ecology. It has the advantages of light weight, easy processing, good nail holding force and no deformation, and is an ideal material for interior decoration and high-grade furniture production.
2. Compared with solid wood board, joinery board is stable in size, difficult to deform, effectively overcomes the anisotropy of wood and has high transverse strength. Because the principle of symmetrical blank assembly is strictly observed, the warping deformation of the plate is effectively avoided. The joinery board has beautiful surface, wide format and convenient use.
3. The joinery board has the characteristics of good screw grip, high strength, firmness, sound absorption and heat insulation. The moisture content of blockboard is not high, which is between 10%- 13%. Easy to process, widely used in furniture, doors and windows and sleeves, partitions, fake walls, heating covers, curtain boxes and so on.
4. Due to the internal use of solid wood strips, the requirements for processing equipment are not high, which is convenient for on-site construction.
Disadvantages of joinery board:
1. Because urea-formaldehyde glue is widely used in the production of blockboard, the formaldehyde emission is generally high and the environmental protection standard is generally low, which is also the reason why most blockboards have a pungent taste.
2. Most of the joinery boards on the market cut corners in production, and there are large gaps when the solid wood strips are spliced, and there are holes in the boards generally. If nails are nailed in the gap, there is basically no nail holding force.
3. The solid wood strips inside the blockboard are spliced vertically, so the vertical bending and compressive strength is poor, and long-term stress will lead to obvious lateral deformation of the board.
4. The solid wood strips inside the blockboard are made of different materials and have different densities, which are easy to warp and deform after simple drying; The structure is twisted and deformed, which affects the appearance and use effect.
Because of the rough surface of blockboard, carpenters usually use a lot of glue or paint when processing the surface on site, so the furniture made of this board is extremely environmentally unfriendly, which is also the main reason for the pungent smell when decorating. This kind of furniture made on the spot is the chief culprit of cancer and gene mutation, which is very harmful to human body.
