蓖麻秆刨花板的最佳制板工艺参数

Study on Optimal Technology Parameter for Particle Board Manufacturing with Ricinus communis Stalk

采用多因素多水平法,对100种不同工艺条件下制造的刨花板的性能进行研究,用于确定板材的最佳工艺参数。用主成分分析法对板材的综合性能进行研究,在充分考虑板材的生产效率、生产成本和性能稳定性的基础上确定出板材的最佳工艺:热压温度150℃,热压时间30 s/mm,施胶量12%,热压压力3.5MPa;所制板材除吸水厚度膨胀率外,其他性能均可满足国标要求。

The properties of particle board made of Ricinus communis stalk and manufactured by 100 different manufacturing technologies were comparatively studied by multiple factor and multiple level methods in order to screen out the optimal technology parameters. The comprehensive properties of the board were determined by the Principal Component Analysis. With consideration of productivity, cost and stability of the R. communis stalk particle board products, the optimum manufacturing technology was selected with following parameters： the hotpress temperature was 150 ℃ ; the hot - press time was 30 s/ram; the UF added was 12% ; and the hot pressure was 3.5 MPa. The properties of the R. communis stalk particle board could reach or exceed the requirement of PRC standards for particle board products expect to the thickness swelling index.
