| 摘 要： | 评述了国内外钻头润滑脂的配方组成、性能功效和评定设备的发展情况,并针对目前普遍使用的皂基钻头润滑脂存在的相变使这类钻头脂的使用温度受到限制这一事实,提出用非皂基稠化剂生产钻头润滑脂的配方和方法。试验表明,用非皂基稠化剂(耐热膨润土或聚四氟乙烯)调制的钻头润滑脂具有较高的极压抗磨性和耐热性。

| Abstract: | The development in formula and composition,quality and performance, as well asthe evaluation equipment of both the chinese and foreign drill bit greases are discussed, alsoformula and process to produce bit grease using non -- soap thickeners are put forward toovercome the applying temperature limitation in soap grease caused from the phase change in thatkind of bit grease. Test shows that the bit grease prepared with non --soap thickeners (heat -resistant bentonite or polyvinyltetrafluoride)can offer higher extreme--pressure wear--resistanceand heat --resistance. |
