| 摘要:本研究以无机硅酸盐矿物纤维为研究对象，通过对比不同打浆度下的纤维形态变化，分析打浆对纸张性能的影响。结果表明，随着打浆时间增加，浆料打浆度不断提高，束状矿物纤维逐步松解分丝，同时出现明显的细化絮团，纤维湿重随之下降；打浆80 min后，纤维平均长度为576 μm，比未打浆时减少了26.6%，而纤维平均宽度为26.3 μm，比未打浆时增加了11.0%；所制备无机硅酸盐矿物纤维纸的抗张指数呈现先升高后下降的趋势，撕裂指数则随着纤维平均长度的减小而逐步降低；当硅酸盐矿物纤维的打浆时间45 min、打浆度76 °SR、湿重10.6 g时，所制备的无机矿物纤维纸的结合强度达到最佳。 |
| Abstract:This study focused on inorganic silicate mineral fibers as the research subject. By comparing the changes in fiber morphology under different beating degrees， it analyzed the impact of beating on paper properties. The results showed that as the beating time increased， the beating degree of the pulp continuously rose. Bundled mineral fibers gradually loosened and separated into individual fibers， accompanied by the formation of noticeable refined flocs， while the fiber wet weight decreased accordingly. After beating for 80 min， the average fiber length was 576 μm， representing a 26.6% reduction compared to that of unbeaten fibers， whereas the average fiber width was 26.3 μm， showing an 11.0% increase over the unbeaten state. The tensile index of the prepared inorganic silicate mineral fiber paper initially rose and then declined， while the tear index gradually decreased as the average fiber length shortened. When the beating time of silicate mineral fibers was 45 min， the beating degree reached 76 °SR， and the wet weight was 10.6 g， the bonding strength of the prepared inorganic mineral fiber paper achieved the optimal level. |
