滚动轴承或直线运动轴承中的润滑油脂，可能飞溅出颗粒，粘附在液晶制品或硬盘上，导致设备失效。所以，这种设备轴承所使用的润滑油脂尽可能降低飞溅性。但低飞溅性的润滑油脂可能带来耐磨性、噪声、阻力矩等问题。因此，我们需要一种油脂，它既具有低飞溅性，又有较高的性能和使用寿命。为了开发低飞溅性的油脂，作者研究了油脂成分和飞溅性的关系。一些数据下面会提到。飞溅颗粒的多少和基油成分有很大关系，例如，润滑油脂基油是矿物油或合成碳化氢油，它们极性低，飞溅颗粒少；相反，如果是酯油，它的极性高，飞溅性也高。飞溅颗粒的多少也取决于增稠剂的类型和含量，例如浓的润滑油脂的飞溅数量少。作者证实了飞溅出来的颗粒不仅有基油颗粒，而且有细小的油脂颗粒，油脂颗粒的直径范围在０．１１ 到０．２μｍ 。
Grease in rolling bearings or linear motion bearings may spatter particles and adhere to liquid crystal products or hard disks, resulting in equipment failure. Therefore, the lubricating grease used in this equipment bearings to minimize splashing. However, low spatter grease may bring abrasion resistance, noise, drag torque and other issues. So, we need a grease that has both low spatter and high performance and longevity. In order to develop low-spatter oils, the authors studied the relationship between grease composition and splashing. Some data will be mentioned below. For example, lubricating base oils are mineral oils or synthetic hydrocarbon oils, which have low polarity and few spattering particles; conversely, if it is an ester oil, its polarity is high, Splash is also high. The amount of splashing particles also depends on the type and amount of thickener, for example, a small amount of concentrated lubricant splashes. The authors confirmed that the splashed particles include not only base oil particles but also fine grease particles ranging in diameter from 0.11 to 0.2 μm.
