Abstract
The presently disclosed subject matter Is directed to formulations for lubricating a conveyor belt used in beverage packaging. One of the disclosed lubricant compositions comprises water, at least one amphoteric surfactant, at least one anionic surfactant and at least one non-ionic surfactant. Also disclosed is a system for applying a lubricant to a conveyor belt and a method for lubricating a conveyor belt.
Claims59
A lubricant composition comprising:
- 65 wt % to 95 wt % water;
- 1 wt % to 25 wt % of at least one amphoteric surfactant;
- 1 wt % to 10 wt % of at least one anionic surfactant;
- and
- 0.5 wt % to 10 wt % of at least one non-ionic surfactant.
The composition as in any one of the preceding claims, wherein the at least one anionic surfactant comprises at least one member selected from the group consisting of N-acyl-sarcosinates, alkylethercarboxylates, alkane sulphonates, alkyl sulfates, alkyl sulphonates, alkyl ether sulfates, branched alkyl benzene sulphonates, linear alkyl benzene sulphonates and their salts.
The composition as in any one of the preceding claims, wherein the at least one non-ionic surfactant comprises at least one member selected from the group consisting of fatty alcohol polyglycosides, linear alcohol ethoxylates, branched alcohol ethoxylates, alkyl phenol ethoxylates, and alcohol alkoxylates.
The composition as in any one of the preceding claims, wherein the at least one non-ionic surfactant is an alcohol alkoxylate.
The composition as in any one of the preceding claims, further comprising at least one additive.
A system for applying a lubricant to a conveyor belt, the system comprising:
- a container with the lubricant composition as in any one of the preceding claims;
- and
- a device to dispense the lubricant composition as in any one of the preceding claims from the container to the conveyor belt.
A method of lubricating a conveyor belt, the method comprising applying a lubricant composition to the conveyor belt wherein recycled water with anions is in contact with the conveyor belt, wherein the lubricant composition has a coefficient of friction of less than 0.3 when lubricating the conveyor belt and wherein the lubricant composition comprises:
- 65 wt % to 95 wt % water;
- 2 wt % to 5 wt % N-coco, 1,3-diaminopropane;
- 0.5 wt % to 10 wt % N-lauroyl sarcosinic acid sodium salt;
- 0.5 wt % to 5 wt % of at least one non-ionic surfactant;
- 0.5 wt % to 5 wt % of a buffer;
- and
- 0.5 wt % to 3 wt % of a phosphate ester.
A lubricant composition comprising:
- 65 wt % to 95 wt % water;
- 1 wt % to 25 wt % of at least one amphoteric surfactant;
- 2 wt % to 5 wt % N-coco, 1,3-diaminopropane;
- 1 wt % to 5 wt % of at least one buffer;
- and
- 0.2 wt % to 5 wt % of at least one additive.
A lubricant composition comprising:
- 65 wt % to 95 wt % water;
- 0.5 wt % to 15 wt % of at least one cationic surfactant;
- 2 wt % to 5 wt % of at least one non-ionic surfactant;
- 1 wt % to 5 wt % of at least one buffer;
- and
- 0.2 wt % to 5 wt % of at least one additive.
