Anonymous users2024-01-24Particleboard is particleboard, as for what raw materials are, unless they are produced by themselves, it can be controlled, and the finished board is not easy to say.
1. Particleboard is divided into Class A particleboard according to its use; Class B particleboard.
Second, according to the structure of the particleboard: 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.
Fourth, according to the surface condition:
1. Unfinished particleboard: sanded particleboard; Unsanded particleboard.
2. Veneer particleboard: impregnated paper veneer particleboard; decorative laminate veneer particleboard; veneer veneer particleboard; Surface finish: particleboard; PVC veneer, particleboard, etc.
Fifth, particleboard according to the product is divided into low density (gram cubic centimeter), medium density (gram cubic centimeter), high density (gram cubic centimeter) three kinds, but usually the production of density of the particle board is gram cubic centimeter. According to the slab structure, it is divided into three structures: single layer, three layers (including multiple layers) and gradient. According to the water resistance, it is divided into indoor water resistance and outdoor water resistance.
According to the arrangement of the shavings in the slab, there are two types: directional type and random type. In addition, there are various particleboards made of non-wood materials such as cotton stalks, hemp stalks, bagasse, rice husks, etc., as well as cement wood wool boards and cement particleboards made of inorganic adhesive materials. Particleboard is available in a wide range of sizes, ranging in thickness from millimeters to 75 millimeters, with 19 millimeters as the standard thickness.
When evaluating the quality of particleboard, the physical properties often considered are density, moisture content, water absorption, thickness expansion rate, etc., and the mechanical properties are static bending strength, vertical plate surface tensile strength (internal cementation strength), nail grip force, elastic modulus and rigidity modulus, etc., and the process properties have machinability, glueability, paint finishing, etc. For special-purpose particleboard, electrical, acoustic, thermal and anti-corrosion, fireproof, flame retardant and other properties should be considered separately according to different uses.
1. The definitions are different.
Solid wood particle board: It is a wood-based board composed of wood or wooden poles, broken logs, fine wood fibers are used on both sides, long wood fibers are sandwiched in the middle, and glue is applied to the panel under heat and pressure. >>>More
1.Solid wood particle board: sawdust + adhesive molding. The finished product is relatively flat and smooth on both sides. >>>More
It is recommended to use other wooden furniture in the bedroom. >>>More
It is particleboard, and MDF is wood powder with glue.
Solid wood furniture is made of solid wood, with natural patterns of wood, natural beauty, and good quality. MDF is a man-made board made of wood fiber or other plant fibers with urea-formaldehyde resin or adhesive. The nail holding force of MDF is poor, because the fiber of MDF is very broken, the nail holding force of MDF is much worse than that of solid wood board and particleboard.
