Organoclay for Grease Lubricants
Degassing and filtration processes are critical steps in ensuring the final quality of organic bentonite grease.
Air bubbles introduced during dispersion can disrupt the integrity of the gel network, leading to volume expansion or separation during storage.
Vacuum degassing (vacuum pressure -0.09 to -0.1 MPa) for 15–20 minutes removes over 99% of air bubbles, ensuring product structural stability. Filtration uses a 100–150 mesh filter to intercept undispersed coarse particles and external impurities, preventing abrasive wear during equipment operation.
A case study of lubricating grease for construction machinery shows that the degassed and filtered product, when used in loader bearings, reduced operational noise by 3 decibels and extended bearing lifespan to 1.5 times the original duration. Regular inspections of the filter mesh are required during production to prevent blockages that could impair filtration efficiency.
Organoclay for Grease
Organophilic clay CP-720A is a kind of purified and modified organoclay rheological additive, designed especially for using in Grease based on synthetic oils such as vegetable oil, polyester oil. Organic clay has high gelling efficiency, fine thixotropy and perfect anti-settling.
Organiclay bentonite CP-720A is used in the following applications:
Advantages of Organoclay Rheological Additive
Properties of Organoclay
Composition Organic derivative of a montmorillonite clay
Appearance Fine powder, light yellow
Moisture content (105℃,2hr) ≤3.5%
Loss on ignition (1000℃) 34%-36%
Bulk density 0.42g/cm3
Fineness (<74μm, %) ≥98%
Organobentonite Packages
Kraft paper bag with PE liner or multi-wall paper sacks or customized. 25kg/bag or 22.68kg/bag or customized.
Organophilic clay Store in a dry, well-ventilated area with temperature of 0℃-30℃. Keep container closed. The quality guarantee period is 24 months.
When it is used in Grease Lubricant, polar activator is needed. Polar activator is acetone/water(95/5). The dosage of activator is 20%-30% of the weight of CP-720A. And also high shear can promote the dispersing of rheology modifier CP-720A.
Adding procedure as follows:
Note: With High-speed dispersant of grinding machine, and properly prolong the dispersing time, better gelatin performance can be reached.
The Lubricanting grease which uses organoclay as thickener will own high dropping point, thus can be used under high temperature and presents good impermeability and water resistance.
