| Abstract: | In order to explore the production process of thin and long high-density particleboards, particles in special ap-pearance were selected in experiment, which were thin and long. When other elements were fixed, the effects of three technologi-cal parameters, including hot pressing temperature, particleboard density and consumption of adhesive, on MOR, MOE, internal bonding strength and absorbent thickness swelling of the particleboard were studied, and the optimum parameters were obtained.After reasonable analysis on the data, it was concluded that, to certain extent, hot pressing temperature, particleboard density and the consumption of adhesive all had influence on physical and mechanical properties of the particleboard, in which hot pressing temperature and particleboard density had greater effects. The optimum technological parameters are: hot pressing temperature is 155℃, particleboard density is 0.88 g/cm3 and the consumption of adhesive is 12%. |
