Document Type and Number:
WIPO Patent Application WO/2012/017947
Kind Code:
A1
Abstract:
It is possible to control thickening of the processing solution contaminated by scraps by means of at least one water-soluble polymer selected from a copolymer containing (A) polyvinylpyrrolidone and vinylpyrrolidone and in addition by means of a aqueous processing solution for fixed abrasive grain wire saw containing (B) water. It is also possible to control the reaction between processing solution and scraps as well as the generation of hydrogen.
