Solid Wood Multilayer Board, Also Known As Plywood
May 31, 2017

[Solid wood multilayer board concept]

Solid wood multi-layer board, also known as plywood, is birch, poplar, eucalyptus, Paulownia and other pieces of wood cut into veneer, or wooden square cut into thin wood, using the world's leading Bayer soy protein glue for the adhesive, Glued three or more than three layers of thin plate, usually with odd-numbered veneer, and the adjacent layer of the fiber in the direction of the vertical arrangement of glue from the series of wood.

Its surface layer is selected high-quality wood after drying, fat, health after a few steps from the process, the surface should not have decay, dead, wormhole, cracks, folder skin and other defects, but for small knot, color can not Too demanding, because this is a natural property of wood. In some places multi-layer solid wood moisture content is generally 5% -14%.

Solid wood multi-layer board is the use of pure natural wood substrate and soy protein glue adhesive non-formaldehyde added environmental protection process, with expensive, natural, non-formaldehyde release of renewable soybean protein glue instead of the traditional aldehyde glue, to the United States California P2 (formaldehyde release Content ≤ 0.09mg / L) level, with the current domestic highest environmental rating, formaldehyde emission less than the national standard E0 (formaldehyde emission ≤ 0.5mg / L) level of one-fifth, ecologically more environmentally friendly.

Health and environmental protection of solid wood multilayer, in the sheet forming process to avoid the use of liquid glue, formaldehyde is generally present in the liquid glue, so solid wood multilayer board than the particle board more environmentally friendly and healthier. It has all the advantages of natural wood, such as light weight, high strength, beautiful texture, insulation, etc., but also make up for some natural defects in natural wood such as knots, small format, deformation, vertical and horizontal mechanical differences and other shortcomings.

 Relative to the solid wood, but also can achieve the role of saving social resources. It uses fast-growing forest production, in the production process can achieve a reasonable use of logs, save a lot of primary wood.

[Advantages of solid wood multilayer]

Solid wood multilayer board is based on the traditional plywood innovation and development of the second generation of environmentally friendly plywood, in addition to the traditional plywood with insulation, deformation, large format, no warping, light weight, high strength, beautiful texture, construction (High environmental protection, high value, high density, low expansion, no degumming) "quality advantage. It also has the advantages of" three high and one low ", which is not suitable for traditional plywood.

Solid wood multilayer board is a multi-layer veneer to suppress, so solid wood multilayer waterproof and stability are very good, solid wood multilayer strength with its grassroots level, for each additional layer, its strength will be corresponding Enhanced, of course, its price will be correspondingly increased. Solid wood multilayer board is a combination of MDF and particleboard advantages. Both the structural stability of the MDF, moisture, moisture, and the particle board of light, easy to move, and no hard wood processing, can not be the second disassembly, not susceptible to environmental impact. The drawback of the solid wood multilayer board is that the price is also higher than that of the particle board / MDF because the production cost is higher than that of the particle board / MDF.

1, high environmental protection: solid wood multilayer board does not contain formaldehyde and benzene, health and environmental protection, 100% non-toxic harmless, is the real health of environmentally friendly wood, the detection of solid wood multilayer formaldehyde emission of not more than 0.1 mg / m , In line with the world's most stringent F4 star standard, can be called zero formaldehyde. Truly realized from the production, distribution, construction and use of the four links of health, environmental protection.

2, high value: plate price, health is priceless.

3, high density: solid wood multilayer production process using high temperature, high pressure, hot pressure for a long time. Hot pressing temperature is more than 30% higher than the traditional plywood; hot pressing pressure is twice that of traditional plywood; hot pressing time is three times that of ordinary plywood; so the density of solid wood multilayer board is 30% higher than that of traditional plywood, Tight, more nail holding force, higher flexural compressive strength.

4, low expansion: solid wood multilayer hot pressing time is long, low moisture content of the plate, no expansion, no shrinkage, no deformation.

5, not degumming: the use of soy protein glue for the adhesive, protein adhesives volatile particularly low, different from formaldehyde has a very strong volatility, no external force is not degumming.
