    Abstract: Emulsifiable compositions are obtained consisting essentially of defined amounts of a long chain fatty acid partial ester of hexitol anhydride, a polyoxyethylene derivative of hexital anhydride partial long chain fatty acid ester, an alkylaryl polyether alcohol having a short polyether chain, and normally liquid oil of lubricating viscosity. These emulsifiable compositions can also contain minor amounts of lard oil and a light petroleum fraction, such as kerosene. A small amount of the emulsifiable composition, such as about 1 to 4 weight percent, is dispersed in water and forms a stable emulsion which is useful as a lubricant in grinding of glass with a diamond grinding surface. These new compositions are characterized by the ability to form and maintain oil-in-water emulsions which are stable for extended periods of time under severe conditions of use and increase diamond life, with small, economical amounts of lubricant being consumed. Other advantages are that the lubricating compositions of this invention require less spindle power with less pressure to obtain the same glass surface finish.

    Abstract translation: 获得的可乳化组合物基本上由限定量的己糖醇酐的长链脂肪酸偏酯,己酸酐部分长链脂肪酸酯的聚氧乙烯衍生物,具有短的聚醚链的烷基芳基聚醚醇和通常为润滑的液体油组成 粘度。 这些可乳化组合物还可以含有少量的猪油和轻质石油馏分,例如煤油。 将少量可乳化组合物,例如约1至4重量%分散在水中并形成稳定的乳液,其可用作用金刚石研磨表面研磨玻璃的润滑剂。 这些新组合物的特征在于能够形成和保持水包油乳液,其在恶劣的使用条件下长时间稳定并且增加了钻石寿命,同时消耗少量经济的润滑剂。 其他优点在于,本发明的润滑组合物需要的主轴功率较小,压力较小以获得相同的玻璃表面光洁度。
