①. The dropping point is an indicator of the heat resistance of the grease, and the high service temperature of the grease can be roughly understood through the dropping point. Generally, the maximum service temperature of the grease should be 30-50°C lower than its dropping point. For the use of low speed, the maximum service temperature of the grease can be 15-30°C lower than the dropping point. There is no direct relationship between the dropping point of high dropping point greases such as complex soap base grease and bentonite grease and high service temperature. It should be noted that the dropping point is not a parameter that determines the high service temperature of a grease. To determine the high service temperature of lubricating grease, in addition to dropping point, it also depends on its consistency at high temperature, and the antioxidant capacity of base oil and thickener. Parameters such as colloidal stability at high temperature.
②. The general type of grease can be roughly judged by the dropping point.
③. When preparing grease, the dropping point can be used as a quality control item. For the same type of grease between successive batches, if the dropping point fluctuates greatly, it indicates that there is some abnormality in the properties of each component or the proportion of each component or the manufacturing process.
