| 中文摘要: |
| 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/m²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%。 |
| Abstract: |
| 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/m2 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. |
