Lubricating grease

For the lubricating grease which contains organic bentonite, in order to achieve the best performance, you need to add polarity activator into the system. The activator used in lubricating grease production (with organic bentonite) is listed as below:

Acetone, methanol(95%), ethanol (95%), propylene carbonate, ether derivatives

Usually, the preferred activator is carbonate propylene ester glycol ether derivatives, because the use of acetone and methanol (95%), ethanol (95%) will cause a low flash point of the grease. The production of grease which use organic bentonite, such as HY-738 and HY - 758, in the final stage need high shear force to achieve the ideal expansion, using colloid mill can achieve high shear force.


The add method of HY-738:

1, Make the temperature to 60~80°C .

2, stirring while adding HY-738 (6~10% of the total system) stirring for 10~20 minutes.

3, add the polar activator (3% carbonate propylene ), then add additives, preservatives, antioxidants, metal purification agent, stirring for 25~30 minutes.

4, Use pump make it through the colloid grinding or homogenizer.

5, Outgassing, filtering, then packing the lubricating grease.


The add method of HY-758:

1, heating the 1/3~1/2 grease's temperature to 60°C .

2, stirring while adding HY-758 (6~10% of the total system) stirring for 10~20 minutes.

3, add the polar activator (3% carbonate propylene), stirring for 25~30 minutes.

4, under the condition of stirring, the required additives are added to the remaining grease, stirring for 25~30 minutes.

5, Use pump make it through the colloid grinding or homogenizer.

6, Outgassing, filtering, then packing the lubricating grease


The advantages of lubricating grease with organic bentonite:

1, Make the high boiling point lubricating grease used in high temperature.

2, Based on organic bentonite gelling agent, lubricating oil can also maintain good lubrication even at a low temperature.

3, Lubricating grease with gelling agent has excellent anti - permeability

4, it has excellent water resistance.
