中文摘要:

以一次性竹筷为原料,采用预水解与硫酸盐蒸煮工艺相结合的方法制备浆粕,考察预水解条件并结合正交试验法对蒸煮条件进行筛选,同时利用光学显微镜观察纤维微观形貌。结果表明,较佳的制备条件为预水解时间30min,酸的质量分数1%,蒸煮时间110min,硫化度23%,绿氧用量0.3%,用碱量15%。在此实验条件下可制得得浆率45.68%,卡伯值74.8,聚合度307.03的浆粕。光学显微镜的观察结果表明,所制得的浆粕纤维表面结构受到破坏,纤维表面出现不均匀的裂纹与凹槽。

英文摘要:

Abstract : The bamboo pulp was prepared by the method of preliminary hydrolysis and kraft cooking with the disposable chopsticks as raw materials. The preliminary hydrolysis conditions were discussed and the kraft cooking conditions were investigated in detail with orthogonal design method, and the optical microscope was used to observe the structure of micro fibers. The results showed that the optimal reaction conditions were the preliminary hydrolysis time of 30 min, the acid content for 1% the kraft cooking time of 110 min, the sulfidi ty content for 23%, green oxygen content for 0.3%, the alkali charge content of 15%. The verification test results showed that the yield of pulp can amount to 45.68%, kappa number for 74.8 and the degree of poly merization for 307.03. It was also observed with an optical microscope that the structure of micro fibers was damaged surface. by preliminary hydrolysis and kraft cooking, and some cracks and grooves were emerged on the fiber
