摘要:研究了6种玻璃棉纤维的纤维形态及疏解对其纸张性能的影响。利用Morfi纤维质量分析仪对玻璃棉纤维进行分析,探讨了打浆对玻璃棉纤维形态的影响以及疏解对玻璃棉纸张性能的影响。研究发现,打浆对玻璃棉纤维的长度、平均粗度及扭结角的作用不大,而纤维的平均宽度、扭结纤维比例和卷曲纤维比例受打浆度的影响较大。疏解对BM-3纤维的纸张厚度和导热系数影响比较明显,当疏解转数小于15000转时,BM-3纤维纸张的导热系数最小。疏解对BM-1纤维纸张的透气度影响最大。

Abstract:Morfi fiber quality analyzer was used to study morphological characteristics of glass microfiber wool and the effect of disintegration of the glass wool on the property of the paper made of the glass fibers. The results showed that the thermal insulation performance of the papers made of BM-3 glass microfiber wool was better. It was mainly attributed to the smaller kink and larger crimp of BM-3 glass microfiber wool which could interweave more closely after paper making and provide better thermal insulation performance. Glass wool fiber number increased, and size decreased when the glass wool was refined and with the increase of the number of refining revolution. The pore of the papers, the thickness and air permeability of the paper decreased greatly with refining revolution increases. The thermal conductivity of the papers made of BM-1 and BM-3 increased at the beginning then tended to be stable, the thermal conductivity basically unchanged as the number of refining revolution was about 15000 r.
