摘　　要：根据有机化学基本原理以及课题组前期总结有机物分子结构与砂轮堵塞间的交互规律,讨论并确立了陶瓷专用磨削液最佳抗堵塞添加剂应具备的分子结构特征。依据该特征设计并选择了月桂酸钠和硬脂酸钾这两种优化添加剂进行试验和验证。试验结果表明:在非极性氮化硅陶瓷磨削过程中,月桂酸钠应用效果最佳,完全抑制砂轮堵塞现象的发生。在极性陶瓷氧化铝磨削过程中,两种试剂也可以起到明显的抗堵塞效果,但抗堵塞能力相对较差。在此基础上,文章讨论了有机物在陶瓷表面的吸附形式与抗堵塞特性之间的交互关系。Based on the basic principles of organic chemistry and our previous summary on jam of grinding wheels, the molecular structure for the best anti-clogging additives have been established. According to the principle, sodium laurate and potassium stearate were selected and tested. The results show that for the non-polar Si3N4 ceramic, the sodium laurate can give the best efect to reduce jam on the surface of grinding wheels. For the polar alumina ceramic, two agents can also play a significant anti-clogging effect, but their ability is relatively poor. Then on the base of these, the paper discusses the relationship between organic materials adsorption forms on surface of ceramic and their ability to anti-clogging.
