How to distinguish the advantages and disadvantages of high temperature grease?

一、Appearance

1. Volume

①Advantages: Because no powder is added, the volume is large;

②Disadvantages: Added filler, small size;

2. Smell

①Advantages: There is no strange smell, only a faint smell of extreme pressure agent;

②Disadvantages: There is an odor of pickling oil or regenerated oil

二、 Smoke

1. Volume

① Advantages: light gray smoke, uniform flame during combustion, uniform and stable dripping;

② Disadvantages: Thick black oil smoke, unstable flame during combustion, and deflagration;

2. Residues

① Advantages: There is almost no residue after combustion, only a small amount of soap ash remains. The high-temperature fat soap content is about 11%, and the ash after combustion is about 4%;

② Disadvantages: Large pieces of powdery ash remain after combustion, which may be additives or pennant soil. The more ash, the shorter the use time and serious wear on the wheel hub.

三、 Feel

①Advantages: All produced with national standard oil, similar viscosity meets the standard, excellent high and low temperature resistance, will not become hard or soft due to seasonal changes, and has moderate wire drawing;

② Disadvantages: Quality: Produced with non-standard large viscosity oil, poor high and low temperature resistance, soft in summer and hard in winter, seasonal differences are very obvious, long wire drawing

四、 High temperature thermal reversible characteristics

When the vehicle is driving, the road conditions and working conditions are complex, and instantaneous high temperatures are very likely to occur. The high-temperature thermal reversible feature can effectively extend the service life and effectively reduce the phenomenon of wheel hub burning and axle locking;

The high-temperature thermal reversibility properties of grease mean that the grease begins to melt when exposed to high temperatures, but it can maintain the structure of the soap from being destroyed for a certain period of time. When the temperature drops, it returns to grease and still has good lubrication properties.
