摘要
在试验与生产结合的情况下,通过正交方法研究了桉木胶合板的制造工艺,运用极差和方差联合进行分析,得出了桉木生产的最佳工艺参数,即桉木的涂胶量是290g/m2,热压时间是1.9min/mm,热压压力1.4MPa,热压温度是115℃,在此参数组合下,桉木胶合板的性能达到最好,其耐水胶合强度满足Ⅱ类胶合板的要求,为1.89MPa,静曲强度54.45 MPa,弹性模量7071MPa。
This paper researched the production technology of the Eucalyptus plywood by the orthogonal experiment method under the case of combination of experiment and production.And then used the range method and variance method to analyse the data,and get the optimal technical parameters,namely the glue spread is 290g/m2,the hot pressing time is1.9min/mm,the hot pressing pressure is 1.4MPa,the hot pressing temperature is 115℃.With the optimized parameters,The wet bonding strength is 1.89MPa which meets the demand of the Class II plywood,the MOR is 54.45 MPa,the MOE is 7071MPa.
