Title
(EN) SLURRY COMPOSITION CONTAINING NON-IONIC POLYMER AND METHOD FOR USE
Abstract
(EN)
A WIRESAW CUTTING FLUID COMPOSITION OF THE PRESENT INVENTION COMPRISES 25 TO 75 % BY WEIGHT OF A PARTICULATE ABRASIVE SUSPENDED IN AN AQUEOUS CARRIER CONTAINING A POLYMERIC VISCOSITY MODIFIER THAT COMPRISES A POLYMER INCLUDING A MAJORITY OF NONIONIC MONOMER UNITS (PREFERABLY 100 MOL % NON-IONIC MONOMER UNITS), HAS A NUMBER AVERAGE MOLECULAR WEIGHT (Mn) OF AT LEAST 5 kDA, AND IS PRESENT IN THE COMPOSITION AT A CONCENTRATION SUFFICIENT TO PROVIDE A BROOKFIELD VISCOSITY FOR THE COMPOSITION IN THE RANGE OF 50 TO 1000 cP, E.G., 50 TO 700 cP, AT 25 ?C AT A SPINDLE ROTATION RATE OF 60 RPM. IN ONE EMBODIMENT, THE VISCOSITY MODIFIER COMPRISES A POLYMER HAVING A WEIGHT AVERAGE MOLECULAR WEIGHT (Mw) OF AT LEAST 200 kDa. WHEN A VISCOSITY MODIFIER OF 200 kDa OR GREATER Mw IS UTILIZED, A PREFERRED WIRESAW CUTTING METHOD THE CUTTING FLUID IS CIRCULATED AND APPLIED BY PUMPS AND NOZZLES OPERATING AT A RELATIVELY LOW SHEAR RATE OF NOT MORE THAN 10? S-?.
