摘要
以烘干漂白麦草浆为原料,用六甲基二硅胺烷(HMDS)进行处理,观察处理前后二次纤维的角质化程度和强度性能,扫描电镜(SEM)观察纤维表面形态,并抄纸比较纸页性能变化.发现经HMDS处理能降低二次纤维的角质化程度,增强纤维的结合力和强度,大大提高纸页的强度性能.本法所用药品容易回收,且可循环使用,成本低而无污染.为二次纤维的推广使用提供了行之有效的解决办法,可缓解我国目前造纸原料短缺的矛盾,因此有一定的经济效益和社会效益.
Dried straw pulp was treated with hexamethyldisilazane(HMDS) . Hornification and strength properties of the secondary fibers were studied .The morphologies of secondary fibers were observed by a Scanning electron microscope (SEM),and the properties of their paper were further researched. The results showed that the HMDS treatment could reduce the Hornification of secondary fibers and enhanced the bonding properties. The strength properties of their papers were improved greatly. Chemical reagents was recycled easily, with low cost and no pollution. It provides an effective measure for using secondary fibers and resolving our material shortage. So, there will be fairly good economic benefits and social benefits.
