【摘要】 以国内南方的马尾松纤维为原料,利用高速搅拌作用将二氧化钛粒子加填进入纤维细胞腔内,探讨了加填工艺参数及助剂阳离子聚丙烯酰胺(CPAM)的使用对加填的影响,用扫描电镜观察了加填前后纤维的横截面。结果表明:打浆后的浆料纤维不适用于细胞腔加填;混合搅拌30～45min、浆料浓度0.5%～2.0%时加填效果较好;增大填料浓度能提高加填量;使用CPAM能提高加填量,其使用量0.05%～0.4%时效果较好;电镜观察显示加填后填料粒子很好地留着在细胞腔内。更多还原

【Abstract】 With South China’s masson pine fiber as raw material, titanium oxide particle was loaded into fiber cell lumen with high speed stirringaction. The technological parameter for loading and the effect of auxiliary agent cationic polyacrylamide(CPAM) on the loading are investigated.The cross section of fibers before and after loading were observed with scanning electron microscope. The results show that the pulp fiber afterbeating is not applicable to cell lumen loading; the condition for preferable effect is mixture stirring for 30-45min and pulp concentration at 0.5%-2.0%; CPAM can increase loading volume and the preferable dosage is 0.05%-0.4% and the electron microscope observation proves thatafter loading the filler particle can retained preferably in the cell lumen.更多还原
