slijpslib

Slijpslib is a Dutch term that refers to the slurry produced during grinding, lapping and polishing operations. It is a suspension of abrasive particles in a liquid medium, typically water or a coolant, and sometimes oil-based. The exact composition depends on the process, the material being worked, and the desired finish.

Abrasive grains such as silicon carbide, aluminum oxide, or diamond are common components of slijpslib. Particle sizes can range from coarse to fine, and the slurry may also contain metal fines, lubricants, surfactants, and corrosion inhibitors. The appearance varies from milky to dark, depending on the abrasives used and any contaminants present.

Slijpslib is generated by the action of grinding wheels, belts, or polishing pads as material is removed from the workpiece. It serves to lubricate and cool the surface, while carrying away swarf. It is used across metalworking, jewelry making, stone polishing, and other finishing tasks, where the slurry helps achieve the desired surface quality.

Handling and disposal require care. Used slurry can pose health and environmental risks due to metal fines and chemical additives, so personal protective equipment should be worn and disposal should follow local regulations. In industrial settings, filtration or separation can recover usable coolant and reduce waste.
