There are large core board, density board (fiberboard), multi-layer solid wood board, solid wood particle board, cedar board, and paint-free boards.
(1) large core board: also known as blockboard, also called plywood. The board will be processed into a certain specification of wood strips, by the splicing machine splicing and become, splicing and then by the cold, hot press glue pressed into.
Advantages: good nail grip, high strength, with a firm, sound-absorbing, insulation and other characteristics, the moisture content of the woodworking board is not high, between 10% -13%, easy to process.
Disadvantages: the production process uses a large number of urea-formaldehyde glue, formaldehyde emission is high, environmental standards are low, relatively pungent flavor. Veneer material is not the same, the density of different sizes, prone to warping and deformation, affecting the appearance and effect of the use of large-core board surface roughness, the need for on-site carpentry reprocessing.
(2) density board: also known as fiberboard, according to the density of different can be divided into high-density board, medium density board, low-density version, the current market is mainly used in the medium density board, which is often referred to as medium fiberboard.
Advantages: flat, smooth surface, easy to finish processing and gluing. All kinds of wood veneer, adhesive paper film, veneer panels, light metal sheet, melamine board and other materials can be glued on the surface of the density board.
Disadvantages: the interior is a log milled fibers, slightly worse than solid wood particle board, moisture absorption, water absorption, the thickness of the expansion rate is higher. As a result of the need to use a larger amount of adhesive, and its powdered fibers after pressing, it is difficult to release, to a certain extent, the environmental protection factor is not guaranteed.
(3) multi-layer solid wood panels: is made of three or more layers of veneer, thin plate through the wood glue paste high temperature and high pressure manufacturing. The main substrate is a crisscross arrangement of multi-layer plywood, supplemented by polymer glue, high-quality solid wood veneer for the surface of the material, by the cold press, hot press, sanding, health and other procedures to the production and become.
Advantages: the use of veneer longitudinal and horizontal gluing, high temperature and high pressure pressing, structural stability, not easy to deform, high strength, good intrinsic quality, good flatness, solidity, reducing the use of adhesive glue. The production process uses polymer glue to reduce formaldehyde content, green and environmental protection.
Disadvantages: Because the production cost is relatively high compared to other called, so its price is relatively high compared to other plates.
(4) solid wood particle board: branch, small diameter wood, fast-growing wood and other substrates cut into certain specifications of the wood chips, after drying, mixed with aldehyde-free adhesives, hardeners, waterproofing agents, etc., high temperature and high pressure pressure pressure and become a man-made panels, its profile is similar to the granular, so it is known as the solid wood particle board is particle board, the particle board, the "upgraded version! "
Advantages
Advantages: uniform texture, than ordinary particleboard and powdered density board nail grip, resistance to bending pressure, stability are stronger, environmental performance is better than the medium fiberboard. After high temperature, high pressure, sterilization treatment, so it is not easy to mold and insects, is the most good material for the panel furniture industry.
Disadvantages: due to its own structure, resulting in the inability to have too many changes in the shape. Material reasons, if the wood grinding is not organized and level, then it will come out uneven.
(5) fir board: also called fir integrated board, fir finger-jointed board. With a short small material through the finger mortise and tenon joint length, splicing width synthesized large format thick plate, do not use a lot of glue, bonding process characteristics, is one of the most environmentally friendly decorative panels for interior decoration. At present, more is used cedar, so commonly known as cedar board.
Advantages: all high-quality wood, the amount of glue is only seven-tenths of the woodworking board, is an environmentally friendly products. Durable, no insects, deformation, smooth, smooth, making homes, furniture, the surface does not have to paste the panel, labor-saving materials, affordable.
Disadvantages: poor quality, low-priced integrated board, the water content does not meet the standard, easy to deform, time will crack.
(6) paint-free board: the surface of a layer of melamine paper with a wood pattern, so that the good furniture will not have to brush paint, more environmentally friendly? Health.
Advantages: natural texture, clear wood grain, no color difference on the surface of the product, with off-fire self-extinguishing, wash-resistant, wear-resistant, moisture-proof, corrosion-resistant, acid-resistant, alkali-proof, non-sticky dust, not easy to mildew and black. And do not have to paint, can save labor and paint after construction, shorten the construction time.
Disadvantages: higher prices, shorter life, relatively delicate, once broken, very difficult to repair
