    研究形态结构不同的碳酸钙对PVC增塑糊黏度及稳定性能的影响.结果表明:增塑糊的黏度与碳酸钙吸油量不呈现简单的线性关系,还与颗粒粒径分布、比表面积以及颗粒形态相关.当碳酸钙粒径大小及分布存在显著差异时,其颗粒大小及分布成为决定增塑糊黏度的主要因素.

    The viscosity and time-stability of PVC plastisols were studied. The results indicated that the viscosity of plastisols was not linear over the oil absorption but related to the particle size distribution, particle shape and surface area of CaCO_3. The particle size and distribution were the main effects on the viscosity of plastisols when the CaCO_3 particle size and distribution showed different.
