| 摘 要： | 通过一系列试验考察了不同有机物的乳液作为冷却液时金刚石砂轮磨削氮化硅陶瓷的堵塞效果.试验结果表明:短链有机物及烷烃作为磨削液时,金刚石砂轮磨削氮化硅陶瓷会发生堵塞,而包含较强极性基团的长链有机物可以很大程度地降低砂轮堵塞.其原因是烷烃在氮化硅陶瓷表面形成的非极性油膜对非极性的氮化硅磨屑产生较强的吸引而聚集在磨削区,进而导致砂轮堵塞.油膜表面具有一定的极性可以很大程度地缓解磨屑的积聚并降低堵塞现象的发生.通过对几种极性有机物的清洗效果进行分析,探讨了有机物的分子结构特征与其清洗性能的关系.

| Abstract: | A series of experiment were performed to test the cleaning ability of different organic emulsion for Si3N4 ceramic grinding.The experiment results showed that the grinding fluid made by short chain organic substance and alkane will induces the jam of grinding wheels.At the same time,polar organic substance with long carbon chain can suppress wheel loading phenomenon.The main reason of the jam by alkane is the nonpolar oil film surface possesses the strong attraction to abrasive dust of Si3N4,which will led ... |
