Document Type and Number:
WIPO Patent Application WO/2010/113678
Kind Code:
A1
Abstract:
Provided is a water-containing working fluid for a brittle material and a hard material, which is a working fluid for a brittle material and a working fluid for a hard material, comprising (A) water, (B) a water-soluble polymeric compound having an oxygen-containing group and a number average molecular weight of 6,000 to 3,000,000, and (C) a nonionic surfactant having a clouding point of 10 to 70˚C in a 1% by mass aqueous solution. In a loose-abrasive grain method, the working fluid can sufficiently supply a slurry just before processing and has excellent abrasive grain dispersion stability and also has excellent properties of washing and dispersing scraps, and in a method using a fixed-abrasive grain wire saw, the working fluid rarely detaches fixed abrasive grains and has excellent properties of washing and dispersing scraps.
