薄木贴面工艺对板件翘曲度的影响

以红橡、硬枫和黑胡桃薄木和杨木多层板为材料,根据影响薄木饰面家具板件翘曲度的工艺因素,对添加剂、涂胶量、热压压力、热压温度、热压时间5因素进行4水平的L16(45)正交试验,从薄木的木材学特性角度对翘曲度的差异进行了分析,用极差分析法对影响翘曲度的工艺因素进行了剖析。研究表明,对红橡贴面板的翘曲度而言,涂胶量是影响最大的因素;对于硬枫,涂胶量是最大的影响因素;对于黑胡桃,热压温度是最大的影响因素。

Influence of the technological parameters upon the warp degree of poplar plywood for veneered furniture

According to the technological paramefers,making the L16(45) orthodoxy-corrected test by added-material and adhesive content and unit press and temperature and time of hot press which affect the warp degrees of veneered furniture of poplar.Analysing the warp degree from wood characters and studying the processing parameters that affect the warp degrees by the difference method and modes.The result shows that adhesive content is vital,temperature is minor and the added material is little to the warp degrees of red-oak-veneered parts.But the adhesive content is vital,the hot time is minor and the press is little to the warp degrees of maple-veneered parts,and the time is vital,the adhesive content is minor and the press is little to the warp degrees of maple-veneered parts.
