| 摘 要： | 通过对碳化硅水基浆料相对沉降高度的测量及不同实验条件下浆料粘度的测定,研究了添加剂用量、固相含量及剪切速率对碳化硅泡沫陶瓷用水基浆料稳定性、触变性及粘度的影响。结果表明,浆料的粘度随剪切速率增加而减小,随固相含量增大而增大,而且具有明显的时间依附性。添加剂PAM的最佳质量分数为0.08%,固相含量在62%左右,浆料的稳定性、触变性较优。

| Abstract: | The effect of additive content, solid content, rotational rate on slurry stability, thixotropy and viscosity were investigated by measuring relative sedimentation height and viscosity of silicon carbide aqueous slurry with different experimental conditions. The results present the viscosity of slurry decreased with rotational rate increased, increased with solid content increased, and take on obvious behavior of cling to time. The optimum amount of PAM is 0.08% and solid content at 62%,slurry have better stability and thixotropy. |
