摘要
在分析玻纤单丝向玻璃微珠转化的理论基础上,以石墨板承载热处理试验,研究玻纤废丝转化为玻璃微珠的转化过程及单丝长度、热处理温度与时间对微珠化的影响。热膨胀曲线测定、显微镜观察微珠情况等手段表明:在高于玻纤软化点110℃左右的温度下热处理20 min左右,能使玻纤单丝转化为具有较高球形度的玻璃微珠;微珠直径主要受单丝长度与直径的影响,长度越大,需要热处理时间越长,甚至难以转化为玻璃微珠。
Based on the theoretical analysis of glass filaments conversion to glass beads, with graphite plate bearing heat treatment test, study the transformation process of glass fiber waste into the glass beads and influence of filament length, heat treatment temperature and time on the beads. Measure of thermal expansion curve, observe of microscope beads shows that glass fiber monofilament can be translated into glass beads with a higher degree of spherical by heat treatment for 20 min in around 110 ℃ higher than glass fiber softening point; Beads diameter mainly affected by length and the diameter of filament, the longer of the length, the the greater of the heat treatment time need, even hard to translate into glass beads.
