What are the classifications of boards?

1. Ecological paint-free board - paper with different colors or textures is soaked in melamine resin adhesive, then dried to a certain degree of solidification, and then paved on particle board, moisture-proof board, Decorative boards made of medium density fiberboard, plywood, blockboard, multi-layer board or other hard fiberboard surface, which are hot-pressed.

2.3D solid wood board - solid wood board is a wood board made of complete wood (logs). Solid wood boards are generally classified according to the name of the board substance (log material), and there is no unified standard specification; solid wood boards are durable and have natural texture. Most of them have the unique aroma of natural wood, have good hygroscopicity and breathability, and are beneficial to human health. , does not cause environmental pollution, and is a high-quality board for making high-end furniture and decorating houses.

3. Wooden board veneer is a current practice in some high-end decorations. Generally, a 3mm decorative panel is attached to the 9mm base plate, and then fixed with mosquito nails. The main reason why wood veneer can be made into various shapes is that it appears, and wood veneer panels have various natural textures, which can bring gorgeous effects to the interior.

4. Blockboard - refers to a special type of board made based on the production of plywood, using wooden slats or hollow boards as core boards, covered with two or more layers of plywood on both sides, and pressed by glue plywood.

5. Multi-layer board - Multi-layer board has a more popular name, plywood. It is made of wood segments that are rotary cut into thin veneers. Sometimes it is also sliced ??into thin wood. , a multi-layer board made of glue and then glued together with adhesive.

Generally speaking, the structure of plywood must abide by the production principles of symmetry and perpendicular fibers of adjacent layers of veneers. Therefore, when selecting multi-layer boards, choose those with clear wood grain and uniform color. , a plate that looks smooth and smooth in appearance and feels flat and not rough.

6. OSB board - OSB board is European pine board. It is made of small diameter wood, thinning wood and wood core, and is processed into long shavings (usually 40-100mm long, 5-20 mm wide, 0.3-0.7 mm thick), a directional structural plate made by processes such as degreasing, drying, sizing, directional paving, and hot pressing.

7. Flame-retardant board - Flame-retardant board, also known as flame-retardant board, includes flame-retardant density board, flame-retardant plywood, etc. In the production process of artificial boards, it is made through complex processes. Fire retardants are added to artificial boards made in the board production line.

8. Integrated lumber - Integrated lumber is also known as finger-jointed board, finger-jointed lumber or integrated board. Solid wood laminated lumber refers to narrow and short wooden strips that are lengthened using adhesives (some boards are made of toothed wood. type connection), and then spread the wide boards horizontally and sand the upper and lower sides. The process of solid wood integrated lumber is basically the same as that of solid wood wide paneling, but because the material specifications are smaller, there are many splicings in the length direction, that is, the panels are made of small pieces of solid wood that have been deeply processed like "fingers". The wooden boards adopt a zigzag interface, which is similar to the interlocking fingers of two hands, so it is called finger-jointed board. Since the log strips are cross-bonded, the bonding structure itself has a certain bonding force, and since there is no need to glue the surface panels up and down, the amount of glue used is extremely small.

9. Gypsum board - Gypsum board is a material made from construction gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, and good sound insulation, heat insulation and fire prevention properties. It is one of the new lightweight panels currently being developed.
