The Direct Characterization for the Modified Filler by Oil Absorption Ratio
The method for characterizing the modified filler directly by oil absorption ratio was studied.The oil absorption ratio of heavy CaCO3 is decreased with the increase of modifier amount in the early stage,but then a slow decline was observed after an inflexion point.The optimal amount of the modifier was calculated at the inflexion point of the curve ofoil absorption ratio.The results showed that the optimal amount of the modifier for 400 mesh,700 mesh,1000 mesh and 2000 mesh CaCO3 was 0.8%,0.9%,1.0% and 1.5%,respectively.The CaCO3 powder was treated with the modifier at the optimal amount,then the masterbatch was prepared by the modified CaCO3.The melt-flow rate experiment for the masterbatch showed that the direct characterization method for the CaCO3 powder was efficient when its particle size was between 400 and 1 000 mesh.
