The Difference between Particle Board and Solid Wood Particle Board

图片
Particle board   and solid wood particle board are both artificial board materials, and there are some differences between them. Here are some main differences between them: 1. Different raw materials: Particle board is made from wood chips and shavings, while solid wood particle board is made from wood, small wood pieces, or wood waste. 2. Different density: Particle board has a lower density, usually between 0.8-1.2g/cm3, while solid wood particle board has a higher density, usually between 0.9-1.3g/cm3. 3. Different manufacturing processes: Particle board is made by mixing the wood chips and other raw materials together, and then pressing them into sheets. Solid wood particle board is made by mixing wood, small wood pieces, or wood waste materials together, and then pressing them into sheets. 4. Surface treatment varies: The surface of particle board is usually treated with surface coatings, while the surface of solid wood particle board is typically treated using methods such as pa

Assessment of the Quality of Particle Board

Particle board , also known as chipboard, is a type of engineered wood board produced by cutting fast-growing timber and wood chips into certain-sized fragments. After drying, it is mixed with glue, hardening agents, waterproofing agents, etc., and pressed under specific temperature and pressure to form a board. The arrangement of particles is not uniform. Although particle board is also called chipboard, it is not the same as solid wood particle board. Solid wood particle board has a similar manufacturing process to particle board but is far superior in quality. 1. From the appearance, the size and shape of the wood chips in the central area of the cross-section should be observed. Usually, the length is between 5-10mm. If it is too long, the structure will be loose, if it is too short, the resistance to deformation will be poor, which means the static flexural strength does not meet the standard. 2. The moisture resistance of engineered boards depends on their density and moisture re
