Abstract
A lubricant concentrate comprising an effective lubricating amount of at least one ether carboxylate and at least one foam destabilizer, and methods of using the same. The lubricant concentrate may be diluted with water prior to use.
Claims70
A lubricant concentrate comprising an effective lubricating amount of at least one ether carboxylate and at least one defoamer.
An aqueous conveyor lubricant composition comprising from about 0.1 wt-% to about 50 wt-% of at least one ether carboxylate having the following general formula:
- R—(OCH2CH2)n—OCH2COO—X
- where X is an alkali metal, amine, alkanolamine, ether diamine, ammonium salt or H (free acid), R═C12-C18, and n is about 6 to about 1, and at least one foam destabilizer.
A method of lubricating the interface between a container and a moving conveyor surface, the method comprising the steps of:
- a) providing a lubricant composition comprising at least one ether carboxylate lubricant and at least one foam destabilizer;
- and
- b) applying said lubricant composition to said conveyor surface.
A method of lubricating a conveyor system comprising the steps of:
- a) diluting a lubricant concentrate with water to form an aqueous lubricant use-solution comprising an effective lubricating amount of at least one ether carboxylate and foam destabilizer;
- and
- b) applying said lubricant use-solution composition to the intended surface of use.
A method for lubricating a continuously-moving conveyor system for transporting packages said conveyor system is wetted with an aqueous lubricant composition comprising at least one ether carboxylate lubricant and at least one foam destabilizer.
