The results indicate that the deviation of viscosity concentration is still not acceptable for most of the pigments, although the solid content of pigment slurry is well linear with the reciprocal of the square root of viscosity.
结果表明,尽管颜料悬浮液固含量与黏度平方根倒数的线性关系相当好,但对于相当一部分颜料,由此得到的黏浓度数据偏差仍然不可接受;而且根据测算,在黏浓度点附近,固含量的微小波动会造成低剪切黏度很大的变化,导致黏浓度的测定结果不可靠。
50% respectively,and the viscosity concentrations were 69.
50%,这两种体系的黏浓度分别为69。
