Grease viscosity temperature performance indicators, commonly used viscosity index to indicate an agreed value. The greater the viscosity index, the less the viscosity is affected by the temperature, we will know that there are many kinds of grease, but why these greases put that mixed together to use it, the following I will tell you why grease can not be mixed.

1, drop point change: mixed with no drop point of organic soil and silicone grease, the drop point remains unchanged; mixed with soap-based and polyurea grease after the drop point are obvious changes, when the proportion of less than 15%, the change is very small, when the proportion of mixed with 50%, the drop point than the drop point of the two greases alone are low, indicating that the mixed grease internal colloidal structure has been damaged to a certain extent.

2, consistency change: consistency with the increase in the mixture of proportion is gradually becoming thin trend, when the mixture of proportion reached 50/50, the degree of thinning reached the maximum, only when mixed with 75% of the composite aluminum base grease thickening phenomenon, the change range in 0 ~ 60 units.

3, bearing leakage: bearing leakage with the doping of the second component grease ratio increases and increases, and then gradually tends to stabilize, further increase the doping ratio, and a declining trend, the size of bearing leakage and consistency, drip point, shear various data changes between no direct correspondence, but the trend of change is basically the same.

4, stencil oil changes: stencil oil changes with the doping ratio of the second component grease ratio increases and increases, and the consistency of the change is a certain correspondence, mixed with organic soil grease, stencil oil increase the largest amount, indicating that its colloidal stability is the worst.

5, blended into the proportion of the second component grease own shear stability is good, its change value is small; conversely, the change value is larger.

The above is why grease can not be mixed with the sharing, if you want to know more information, please pay attention to this site.
