Particle Board for Construction
Particleboard Advantages
A. It has good sound absorption and sound insulation properties; particleboard is heat-insulating and sound-absorbing;
B. The interior is granular with a cross-staggered structure, the performance of each part is basically the same, and the lateral load-bearing capacity is relatively poor;
C. The surface of the particle board is smooth and can be used for various veneers;
D. In the production process of particleboard, the amount of glue used is small, and the environmental protection factor is relatively high.
Particleboard Quality Judgment
1. From the appearance point of view, look at the size and shape of the wood chips in the center of the cross-section. The length is generally 5-10MM in length. If the length is too long, the structure is loose, and if it is too short, the deformation resistance is poor, and the so-called static bending strength does not meet the standard;
2. The moisture resistance of wood-based panels depends on its density and moisture-proof agent. No matter how good the moisture resistance is when soaked in water, moisture resistance refers to moisture resistance, not water resistance, so it must be distinguished in future use. Northern regions, including The moisture content of panels in North China, Northwest, and Northeast China should generally be controlled at 8-10%; in southern regions including coastal areas, the moisture content should be controlled between 9-14%, otherwise the panels are prone to moisture absorption and deformation.
3. In terms of surface flatness and smoothness, generally it has to be polished with about 200# sandpaper when leaving the factory. Generally, it is better to be finer, but at certain times, such as sticking fireproof boards, etc., it is too fine to be bad. Hang glue.
