摘要
利用扫描电子显微镜、X射线衍射、紫外光谱和红外光谱等现代分析技术,对蔗渣爆破法制浆进行了微观研究。研究结果表明,蒸汽爆破后纤维、细胞壁S1和S2层受到不同程度的破坏,使纤维素的相对结晶度增大,而绝对结晶度下降。爆破浆洗涤液的紫外光谱图中,在280 nm处出现了明显的吸收峰,可推断爆破法制浆过程使木素发生了降解。另外,红外光谱图分析表明,爆破处理只是使蔗渣纤维的部分吸收峰的强度发生变化,主体化学结构没有明显变化。
In this paper, the advanced analytic techniques including SEM, X-ray diffraction spectrum, UV spectrum and IR spectrum were apphed to investigate the explosion pulp on a micro-level. The results showed that explosion treatment caused many breakage of fibber as well as S1 and S2 of the wall cell. The relative crystallinity of cellulose treated by explosion increased, while the absolute crystallinity decreased. There was a strong peak in wavelength of 280nm of UV spectrum when the washing effluent was analyzed and this data illustrated that the lignln was destroyed in explosion treatment. In addition, the IR spectrum analysis showed that explosion treament only changed the intensity of the absorption peak partially while the main chemical structure of lignin had not changed yet.
