以107杨为研究对象,采用过氧化氢和冰醋酸混合液对应拉木和正常木进行处理获得2种离析纤维;采用铬酸对正常木进行处理获得1种离析纤维;采用硫酸盐制备正常木化学浆获得1种化学浆纤维,并取出一半化学浆进行打浆处理获得1种打浆纤维。使用原子力显微镜(AFM)对上述5种不同处理方法获得的纤维表面形貌进行观察比较。结果表明,应拉木纤维比正常木纤维容易观测到清晰初生壁表面;铬酸离析方法比过氧化氢和冰醋酸混合液离析方法容易观测到清晰初生壁表面;相比离析纤维,化学浆纤维次生壁微纤丝的定向排列方式清晰可见;打浆后纤维较化学浆纤维,微纤丝定向排列被干扰,出现分丝帚化。
To 107 Yang as the research object, the mixture of hydrogen peroxide and glacial acetic acid was used to treat two kinds of fiber, which were treated with normal wood and normal wood. The normal wood was treated with chromic acid to obtain one kind of isolated fiber. Sulfate was used to prepare normal wood Chemical pulp to obtain a chemical pulp fiber, and remove half of the chemical pulp beating treatment to obtain a beating fiber. Atomic force microscopy (AFM) was used to compare the surface morphology of the fibers obtained by the above five different treatments. The results showed that clear primary wall surface was easily observed in tensile fiber compared with normal wood fiber. Clear primary wall surface was easily observed by chromic acid segregation method compared with hydrogen peroxide and glacial acetic acid. Compared with segregation fiber, chemical pulp fiber Secondary wall microfibrils orientation arrangement is clearly visible; beating fibers than chemical pulp fibers, microfibrils directional arrangement was disturbed, there is split silk broom.
