| titleOfInvention | For the fluidity improver of resin coated sand |
| abstract | The invention discloses a kind of fluidity improver for resin coated sand, be made up of the fatty acid metal salt particle of the divalence of carbon number 8 ~ 24, the relation of A≤2.0 is met with the granularity description value A shown by following formula (1), place under 80 DEG C of environment in this fatty acid metal salt particle of 10 minutes, use powder property tester to measure with the condensation degree B(% shown by following formula (2)) meet the relation of B≤20, granularity description value A=(D90-D10)/D50(but 1.0≤D50≤40.0)? formula (1) D10: in the volume reference of fatty acid metal salt particle 10% accumulative particle diameter (μm) D50: median particle diameter (μm) D90 in the volume reference of fatty acid metal salt particle: in the volume reference of fatty acid metal salt particle 90% accumulative particle diameter (μm) condensation degree B=[(remaining in the quality that sieve mesh is the fatty acid metal salt particle of 350 μm of sieves)/2] × 100 × (1/1)+[(remaining in the quality that sieve mesh is the fatty acid metal salt particle of 250 μm of sieves)/2] × 100 × (3/5)+[(remaining in the quality that sieve mesh is the fatty acid metal salt particle of 150 μm of sieves)/2) × 100 × (1/5)]? formula (2). |
