Grease is formulated with up to 95 percent base oil. Engineering and Design - Lubricants and Hydraulic Fluids. The NLGI consistency number alone is not sufficient for specifying the grease required by a particular application. If the temperature of a grease is lowered enough, it will become so viscous that it can be classified as a hard grease. Complex greases are made by combining the conventional metallic soap with a complexing agent. ASTM D and D methods measure penetration of unworked and worked greases.
Grease Viscosity and NLGI Number Grades
In one example given, a batch produced by homogenization was compared to a batch produced by conventional means. Pilot lights to indicate separate functions Power on, Heating and Cooling Functions. Homogenization of certain types of greases will stiffen the grease producing lower penetration value. Then each molecule of thickener consists of aluminum complexed with stearate, benzoate and hydroxide. Homogenizer Control System including timer and time remaining cycle time. Internal fluid bypass to protect the pump and heating element. The fatty acids usually contain 16 to 18 carbon atoms.
ChevronTexaco Dura-Lith® NLGI Grease EP
Other solid additives produce thickened grease by the nature of their fine dispersion throughout the fluid and by their particle-particle interactions. Our worldwide reputation for manufacturing innovative, dependable products and systems result in a rapidly growing customer base of Grease manufacturers from Canada, China, India, Mexico, Peru, Thailand, United Arab Emirates, United States and other countries. Another type of thickener that is not soap-based is prepared from clays. Homogenizing the grease will break down the solid particles or fibers and will disperse the resultant small particles in the liquid. Conventional double wall jacketed construction for efficient heat transfer.
Description: The homogenizer has sufficient pressure to deliver the grease to any point in the process after it has been homogenized; but a second pump must pick up the colloid mill product, if the grease is to be delivered to another location. Any statements concerning the use of products or processes described above are made for educational purposes only to further the understanding of grease manufacturing. Close-up of Vacuum System. In one example given, a batch produced by homogenization was compared to a batch produced by conventional means. National Lubricating Grease Institute,
