Bulk density 0.42g/cm3
Fineness (<74μm, %) ≥98%
Advantages
High efficiency
The gel is of light colour and high clarity
Easy to use, no need to pregel
Eliminate polar activator
Consistent development of rheology
Can be used to post correct
Application
Bentonite grease CP-250A is used in the following applications:
Grease Lubricant(the base oil is synthetic oil such as middle-high viscosity petroleum, mineral oil, diester oil, polyester oil, vegetable oil etc.)
Wood coating
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-250A. And also high shear can promote the dispersing of CP-250A.
Adding procedure as follows:
If condition permits, heat the base oil to 60~70℃
Add CP-250A while stirring, addition level is 7%-10% of the total formulation. Stir 5~10minutes
Add polar activator, addition level is 2%-3% of the total formulation. Then add other additives, stir 25~30minutes.
Use pump to help it pass colloid grinding and homogenizer.
Deair, filtrate, pack.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.
Package
Kraft paper bag with PE liner or multi-wall paper sacks or customized. 25kg/bag or 22.68kg/bag or customized
Storage
Bentonite grease has a shelf life of 2 years, and should be stored in ventilated cool and dry place.
