Manufacture Of Regenerated Particle Board By The Wasted Particle Products

This article is about the recycle of waste particleboard. In order to find the effect on particleboard's capacity, lots of experiments upon the process of material prepare and hot-press phase have been done. Though the tests on waste particleboard and renzaoban, the best process of material prepare and hot-press phase is fixed.Poach the waste particleboard in the hot water with different temperature and different time; Observ the shape of particle smashed; Taking in to accout of energy wasting and produce efficiency, the best process of material prepare is found; Use orthogonal experiments to make particleboard, then do tests on them. According to the results of tests, choose the rate of waste particle and fresh particle, amount of glue and time of hot-press, then find the best process of hot-press.The result of experiments indicates: taking into the account of the companies' remand in the produce and the condition, such process can be choosed in order to get the best capacity: in the process of material prepare, poach the waste particleboard in the 50 degree water for four hours; in the process of hot-press, hot-press dimension is 400mm×400mm×16mm,aim density is 0.75g/cm~3, amount of glue is 11%,hot press time is 49s/mm,the rate of old paring is 60%.
