摘要
采用氢氧化钠水溶液预处理刨花，并用这些刨花压制单层酚醛刨花板。经１％碱液处理刨花３０ｍｉｎ，可提高板材尺寸稳定性，尤其是可将板材的不可逆厚度膨胀降至极小。
A method of alkaline pretreatment of particles was designed to produce three types of chips.The pretreatment of particles in 1%aqueous solution of NaOH for 30 minutes offered a possibility of producing PF bonded particleboards with minimal irrecoverable swell and a reduction in thickness swelling.The method used in this study could be used to produce more stable PF particleboard.
