在可控施胶压榨设备上,对葡萄牙蓝桉为原料的原纸施加1～5层壳聚糖及壳聚糖衍生物涂布层,通过控制不同的涂布量,研究和评定了壳聚糖涂布纸张的组成结构、物理性能、光学性能、形态学、表面特性和印刷适性。壳聚糖在纤维表面的分布情况用荧光壳聚糖衍生物进行实验分析。结果表明,壳聚糖在纸张表面具有高度均一的分布,并且进行3层涂布后壳聚糖涂料不再向纸页孔洞中渗透;同时,采用壳聚糖涂布对最终的成纸性能有积极的影响。
On the controllable size press equipment, 1 to 5 layers of chitosan and chitosan derivative coating layers were applied on the base paper of Portuguese gum eucalyptus. Chitosan was researched and evaluated by controlling different coating amount. Coated paper composition, physical properties, optical properties, morphology, surface properties and printability. The distribution of chitosan on the surface of the fibers was experimentally analyzed with fluorescent chitosan derivatives. The results show that the chitosan has a highly uniform distribution on the surface of the paper, and the chitosan coating no longer penetrates into the paper hole after three layers of coating. At the same time, Positive effect.
