Abstract
A method of lubricating conveyor tracks or belts is herein described wherein the lubricant composition contains a polyalkylene glycol polymer and a fatty acid; also described are methods of manufacture of such lubricant compositions in both concentrate and diluted form. The compositions may also comprise additional functional ingredients.
Claims46
A method of lubricating a conveyor system for transporting a container, the method comprising:
- applying a lubricant composition to a surface of a belt or track of the conveyor, the lubricant composition comprising:
- a polyalkylene glycol polymer or a derivative thereof;
- and
- a fatty acid.
A method of lubricating a moving conveyor system for transporting a container, the method comprising the step of applying a lubricant composition to a surface of a belt or track of the conveyor system, the aqueous lubricant composition comprising:
- (a) in the range of about 0.001 to about 99% of of a polyalkylene glycol block copolymer or a derivative thereof;
- and
- (b) in the range of about 0.0001 to about 50 wt.-% of a fatty acid.
A method of lubricating a moving conveyor system for transporting a container, the method comprising the step of applying a lubricant composition to a surface of a belt or track of the conveyor system, the lubricant composition comprising:
- (a) a polyalkylene glycol polymer or a derivative thereof;
- and
- (b) a fatty acid, wherein at least a portion of the fatty acid is a free fatty acid that has not been neutralized by an alkali neutralizing agent.
A method of lubricating a moving conveyor system for transporting a container, the method comprising the step of applying a lubricant composition to a surface of a belt or track of the conveyor system, the lubricant composition comprising:
- (a) in the range of about 0.001 to about 99% or a polyalkylene glycol polymer or a derivative thereof;
- and
- (b) in the range of about 0.0001 to about 50 wt.-% of a fatty acid, wherein the composition comprises 100 ppm alkalinity or less.
A method of lubricating a moving conveyor system for transporting a container, the method comprising the step of applying an aqueous lubricant composition to a surface of a belt or track of the conveyor, the aqueous lubricant composition comprising:
- fatty acid;
- polyalkylene glycol polymer or a derivative thereof;
- and
- water, wherein the polyalkylene glycol polymer or a derivative thereof is present in the composition in an amount sufficient to solubilize/emulsify at least a portion of the fatty acid.
