Abstract
The invention relates to the use of at least one polysiloxane in lubricant formulations for reducing friction between conveyor belts and the articles transported thereon. The invention also relates to lubricants containing other additives besides polysiloxane.
Claims60
A method of lubricating the interface between a container and a moving conveyor surface to reduce frictional resistance between the conveyor and the containers transported thereon, the method comprising applying, by direct contact with no dilution of a lubricant concentrate, an effective amount of a liquid lubricant composition between a container and a contact surface of the moving conveyor to reduce frictional resistance between the conveyor and the containers transported thereon, the lubricant comprising an aqueous solution comprising at least one weight percent of a polysiloxane composition based on the liquid lubricant.
The method of claim the 1 wherein the liquid lubricant is sprayed directly onto at least a portion of the contact surface of the moving conveyor.
The method of claim the 1 wherein a liquid lubricant is applied to the moving conveyor through a mechanical device in direct contact with the conveyor surface.
An aqueous lubricant formulated to lubricate the interface between a moving conveyor and a container to reduce frictional resistance between the conveyor and the containers transported thereon, the lubricant composition comprising an aqueous solution comprising at least one weight percent of a polysiloxane polymer based on the liquid lubricant.
The lubricant of claim, 37 wherein the water content is below 10% by weight, based on the formulation as a whole.
