The search for adhesives with abundant resources and low prices is an important factor in the development of particleboard production. Therefore, the effective utilization of forest resources and paper pulping waste liquid has been paid more and more attention. Tannin formaldehyde glue and sulfite pulp waste liquid glue have been used as adhesives, and inorganic adhesives made of cement, gypsum, etc. have also been applied; and more attractive is the new technology of glueless bonding, its emergence This will revolutionize the particleboard industry. As for the particle board itself, since the directional structure is superior to the random structure in terms of mechanical properties, it can be used to replace plywood or even partially sawn board, so it has a great development prospect. More new materials and processes will appear on the surface finish of particleboard, and it is possible to form an independent new industrial category through the specialization of prefabrication of multi-variety multi-functional facing materials.
