The higher the dropping point of grease, the better？

I. The meaning and importance of dropping point

The dropping point is the temperature at which grease changes from a semi-solid state to a liquid state, and is a key indicator for measuring its performance. It reflects the stability and application range of grease at high temperatures.

II. Advantages of high dropping point

1. Good high temperature stability

- High dropping point grease is not easy to lose in a high temperature environment, and can maintain its shape to provide lubrication for equipment and reduce wear. For example, for high-temperature equipment in the metallurgical industry, high dropping point grease can ensure its normal operation, reduce maintenance costs and downtime.

2. Wide applicable temperature range

- It can adapt to working conditions with large temperature fluctuations, such as automobile engines, which have low temperatures at startup and rise after operation. High dropping point grease can effectively lubricate throughout the process, reducing wear and energy loss.

III. Reasons why the higher the better

1. Affecting other properties

- It may sacrifice low temperature performance, become viscous at low temperatures, have poor fluidity, and increase the risk of equipment startup wear. And anti-wear performance may also be affected, and additives or formula adjustments may interfere with the anti-wear effect.

2. Cost factors

- The preparation of high dropping point grease requires special raw materials and complex processes, which increases the cost. For equipment that does not require high temperatures, such as ordinary office equipment, using high dropping point grease will increase unnecessary costs.

3. Differences in actual needs

- Different equipment has different requirements for grease performance, and some pay more attention to water resistance, corrosion resistance, etc. For example, port cranes require good water resistance and corrosion resistance in humid environments, and a high dropping point alone may not be suitable.
