摘要:
 为了实现竹柳材的工业化利用，开发竹柳材刨花板。测定了3年生竹柳材基本物理化学性能；研究了竹柳材刨花的长度、宽度和厚度值的分布规律，探讨热压压力、温度、时间以及施胶量和防水剂添加量对刨花板质量的影响。结果表明：3年生竹柳气干密度为0.463 g·cm-3,体积干缩率为12.90%,pH为3.75,纤维素含量为43.86%,综纤维素为72.31%,酸不溶木素为18.68%,试验所用竹柳刨花长度、宽度和厚度值大致符合正态分布；通过正交试验得出竹柳刨花板的最优生产工艺条件为热压压力3.0 MPa、热压温度175 ℃、热压时间440 s、施胶量10%和防水剂添加量1.0%；最优工艺下的板材性能为：弹性模量2 950 MPa、静曲强度16.1 MPa、内结合强度1.02 MPa和2 h吸水厚度膨胀率6.5%。均达到了GB/T4897.3-2003国家标准要求。
Abstract:
 In order to achieve industrial utilization of Salix discolor timber and to develop particleboard,the physicochemical properties of 3-year-old S.discolor were determined.The distribution patterns of the values of particle length,width and thickness were measured.Influences of the production factors on the quality of the particleboard were discussed,such as the pressure of thermal pressing,temperature,time,resin content and amount of water-proof agent.The results showed that the density of the air-dried timber of 3-year-old S.discolor trees was 0.463 g·cm-3,the volume shrinkage:12.9%,pH:3.75,cellulose content:43.86%,hemicellulose:72.31%,acid insoluble lignin:18.68%.The particle length,width and thickness values roughly presented normal distribution.Through orthogonal experiment,the optimum production conditions of S.discolor particleboard were pressing pressure:3.0 MPa,pressing temperature:175 ℃,pressing time:440 s,resin content:10%,and amount of water-proof agent:1%.Under the optimum process conditions,the performance parameters of the particleboard were the modulus of elasticity:2 950 MPa,the modulus of elastic bending strength value:16.1 MPa,internal bonding value:1.02 MPa and the thickness swelling rate after 2 h water soaking:6.5%,which were in accordance with the national standard.
