The Manufacturing of Rice Straw Particle Board With Modified Phenol-formaldehyde Resin
Introduction Agricultural residues are the renewable resources that can be utilized as raw materials for particle board manufacturing, especially the rice straw due to its availability. Straw contains 29%-35% cellulose, 16%-21% lignin, and 26%-32% pentosan, so it is considered as the alternative to wood fiber. But there are higher amount of SiO2 in the component of the rice straw that formed a non-polar structure on the epidermis of the fiber and a thin layer of wax on the surface, which affected the absorbance of adhesive, combination of hydrogen bonds, and, consequently, the decreasing of the physical and mechanical properties of the particle board. It was of importance that the treating on the surface of the straw was allowed greater penetration of the adhesive to give the rises to the physical and mechanical properties. At the same time, it was necessary to modify the adhesive by adding certain proportion modifier to make the chemical reaction occur easily and yield stronger chemical bonds between adhesive and stalk of the rice straw.
