摘要
通过不同浓度微纳纤丝/MF混合液对秸秆纤维板进行不同浸注时间处理后,分析可知:微纳纤丝的浓度越大,对提高秸秆纤维板的静曲强度和弹性模量效果越好;而增加浸渍时间虽然有利于提高秸秆纤维板的平均密度,但同时会提高其密度梯度。较佳的工艺参数分别是秸秆纤维板密度:0.8g/cm^3;微纳纤丝浓度:1.0%;浸渍时间:8h。
The straw fiberboard was treated by mixtures consist of MF and different concentrations of macro/nano fibrils suspension under different periods of impregnation time. The higher the concentration of micro/nano fibrils suspension was, and the better the MOR and MOE of the treated straw fiberboard would be. Increasing the impregnation time was beneficial to enhancing average density of the fiberboard, but its density grad was also raised. The optimum technology parameters were 0.8g/cm^3 of straw fiberboard density, 1.0% of micro/nano fibrils concentration, and 8 hours of impregnation time.
