Can organic bentonite be added to base oil?
(1) organic bentonite does not change as the phase change of soap, so there is no drop point of bentonite grease, and its high temperature is only determined by the high temperature resistance of surfactant. General bentonite grease can be used at more than 150 degrees celsius.(2) the low temperature of the grease is mainly determined by the low temperature of the selected base oil, and also depends on the amount of thickener.(3) the particle structure of bentonite grease should than soap fiber shear resistance, but because the bentonite has after surfactant treatment, therefore, the mechanical stability of bentonite grease properties with different surfactants and changes. For long periods of use in rolling bearings, the bentonite grease tends to dilute and drain.
Additives and fillers designed to improve some characteristics of greases are added. Grease can be attached to the vertical table... At room temperature under general grease with medium viscosity and high viscosity oil lubricating oil as base oil, there are also some to meet in the harsh by surfactant (e.g. two methyl eighteen alkyl benzyl ammonium chloride and amide) after the treatment of organic bentonite thickening. Or high viscosity oil is made, suitable for truck chassis, driving rudder, universal joint, water pump, hub and bearing lubrication.
) bentonite grease because the bentonite thickener is firmly combined with a base oil, showing its excellent colloidal stability, on the other hand, the base oil is difficult to enter the friction surface, therefore the abrasion resistance and scratch resistance is not ideal, the impact of its use in the high speed rolling bearing.
Because of the poor corrosion resistance of bentonite grease on metal surface, it is necessary to add effective rust inhibitor to improve it.
