摘要
探讨Trametes hirsuta Lg-9预处理玉米秸秆皮机械法制浆,研究Trametes hirsuta Lg-9接种物的菌龄和培养方式,接种后按有无外通空气两种培养方式对秸秆皮机械浆性能的影响。结果显示,按无外通空气方式处理时,13天菌龄的接种物处理样强度性能优于26天菌龄接种物处理得到的秸秆皮浆;固态静置培养接种物处理样强度性能优于液态震荡培养接种物的处理样。与对照样相比,处理样的强度、白度和光散射系数分别降低50%~70%,1%~4%和11%~16%,光吸收系数几乎都高于对照样。处理后的秸秆皮磨浆能耗降低70%~85%。且磨浆能耗与处理后秸秆皮得率间线性相关不显著。
A study on mechanical pulping of corn stalk bark pretreated by Trametes hirsuta Lg-9 was carried out under the cultivation conditions of whether exogenous air was ventilated or not to get the effects of culture age and method of inoculums on properties of corn stalk bark mechanical pulps.The results indicated that while cultivating without exogenous air,the strength of samples that treated by 13 days inoculums were superior to that of treated by 26 days inoculums.And the strength of samples that treated by solid static cultivated inoculums were excelled to those treated by liquid shaking cultivated inoculums.Compared with the control,the strength,brightness and light scattering coefficient of all treated samples were decreased by 50%~70%,1%~4% and 11%~16% respectively while the light absorption coefficients were almost all higher than that of the control.The pulping energy consumption of corn stalk bark treated by Trametes hirsuta Lg-9 was decreased by 70%~85%.The linear correlation between refining energy consumption and yield of corn stalk bark after treatment was not significant.
