Publication number: CN1231954A
Applicant: Wang Fuxing
The straight-grained multi-layered wood consists of an upper and lower surface layer and at least one intermediate layer, wherein the intermediate layer is in the same direction as the upper and lower layers of the wood fibers, and is cut at one side of the intermediate layer. The longitudinal and transverse incisions are arranged at intervals, and the longitudinal incisions and the transverse incisions are discontinuously intersecting. After the combination of the adhesive and the cold press and hot press forming, the twisting deformation will not occur, and the cut surface can be very flush when cutting into a small size, and the processing convenience is convenient. .
Flame retardant particle board production technology promotion
Production and business unit: Wood Industry Research Institute
Prospects for application or promotion: This achievement is a key scientific research project of the Ministry of Forestry, completed by the Institute of Wood Industry of the Chinese Academy of Forestry, and passed the technical appraisal organized by the Science and Technology Department of the Ministry of Forestry in 1991. The flame retardant particleboard is a new type of particleboard which is made of wood or non-wood process shavings, added special additives and adhesives in the process of adding, and is stirred, formed and hot pressed. The physical and mechanical properties reach the national standard GB4897-85 particleboard, low toxicity, and the surface can also be finished. This achievement has solved the key technology of the influence of flame retardant on the strength and hygroscopicity of the board, and is at the leading level in China. Flame retardant performance: Oxygen index above 39 flame penetration time of more than 30 minutes, (thickness 14 mm, temperature 1000 ° C), smokeless, self-extinguishing is suitable for particleboard production line. The product can be applied to the interior partition walls, floors and interior decoration of high-rise buildings with fire protection requirements.
