摘要
以漂白针叶木浆作纤维原料,以表面活性剂为发泡剂,采用泡沫成形技术和平板干燥方式制备了定量为(100±2)g/m^(2)的泡沫成形纸,并考察了3种表面活性剂十二烷基硫酸钠(SDS,阴离子型)、十六烷基三甲基溴化铵(CTAB,阳离子型)、脂肪醇聚氧乙烯醚(AEO-9,非离子型)的发泡性能,以及其对纸张性能的影响。结果表明,3种表面活性剂有不同的发泡特性,AEO-9、CTAB和SDS的最佳发泡浓度分别为1.0、0.5和1.5 g/L。在纤维打浆度为20°SR时,相比传统成形纸,AEO-9泡沫成形制备的纸张,其匀度指数从51.9提升至85.2,提高了64.2%,松厚度从3.95提升至5.43,提高了37.5%。
Using bleached softwood pulp as the fiber raw material and surfactants as foaming agents,a foam-molded paper with basis weight of(100±2)g/m^(2)was prepared by foam forming technology and flat drying method.The foaming properties of three surfactants like sodium dodecyl sulfate(SDS),cetyltrimethylammonium bromide(CTAB),and fatty alcohol polyoxyethylene ether(AEO-9)were investigated,as well as their effects on paper properties.The results showed that the three surfactants exhibited different foaming characteristics,with optimal foaming concentrations of 1.0 g/L for AEO-9,0.5 g/L for CTAB,and 1.5 g/L for SDS.At pulp beating degree of 20°SR,the paper prepared by foam forming with AEO-9 showed that the evenness index increased from 51.9 to 85.2,and the bulk increased from 3.95 to 5.43,with increase of 64.2%and 37.5%,respectively,compared to traditional formed paper.
