摘要

摘要:
为探究硫酸钙晶须增强填料对树脂结合剂磨片的增强效果，采用热压成形方法制备实验样条及树脂磨片，探究不同晶须长度和质量分数对样条硬度、抗弯强度及微观结构的影响，并研究磨片对人造花岗石的磨削性能。结果表明：晶须质量分数不变，随着晶须长度增加，样条的抗弯强度降低，硬度基本保持不变；晶须长度不变，随着晶须质量分数增加，样条的抗弯强度呈先增加后基本不变的趋势；使用磨片对人造花岗石进行磨削，当硫酸钙晶须的长度为10～60 μm，质量分数为10%时，树脂磨片具有最优的耐磨度1.973 min/%，同时具有良好的锋利度76.8 cm³/min。

Abstract:
To investigate the strengthening effect of calcium sulfate whiskers as a reinforcing filler for resin grinding tablets, experimental splines and resin grinding tablets were prepared by the hot pressing method. The effects of different whisker lengths and mass fraction on the hardness, bending strength and microstructures of the splines were examined, and the grinding performances of the grinding tablets on artificial granite were studied. The results show that when the mass fraction of the whisker is constant, the bending strength of the spline decreases with the increase of the whisker length, while the hardness remains relatively unchanged. One the other hand, when the whisker length keeps constant, the bending strength of the spline shows a trend of increasing and then decreasing with the increase of the whisker mass fraction. Using the grinding tablet to grind artificial granite, the best abrasion resistance of 1.973 min/% and good sharpness of 76.8 cm³/min are achieved when the length of calcium sulfate whisker ranges from 10 to 60 μm and the mass fraction is 10%.
