【摘要】 本文从界面浸润理论、界面黏接理论分析出发,探讨一种有可能改善磨料与黏结树脂之间的表界面性能,提高黏结能力,提高砂轮磨削性能的混料工艺及其作用机理。通过加热、抽真空等手段对磨料进行处理,获得了清洁的表面;通过正交试验和方差分析对所制砂轮切割试验结果进行数据处理,结果表明:抽真空和加热均能提高砂轮的磨削性能,抽真空对提高砂轮磨削性能的影响更显著。通过抽真空和加热可改善磨料与黏结树脂之间的表面-界面性能,可提高其黏结能力,提高砂轮的磨削性能。该结论对树脂砂轮的制造具有较好的指导意义。更多还原

【Abstract】 Based on the study about interfacial wetting and bonding principle,this research work searched for a materials mixing technique that may ameliorate the adhesion interaction between abrasive grits and resin bond,and improve the surface-interface energy and grinding ability of the grinding wheels made by.Clean surfaced abrasive grits were obtained by heating and vacuumizing with specific equipment,and then mixed by means of different mixing techniques.Grinding wheels were prepared and tested for their cutting performances.Orthogonal and variance analysis on the wheels’cutting performances and their influencing factors showed that vacuumizing is the most significant factor.Heating and vacuumizing can ameliorate the surface-interface energy of abrasive grits and resin bond and improve the bonding performance,thus improve the cutting performances of the grinding wheels.更多还原
