选用四川和广西具有代表性的CaCO3矿源和CaCO3粉与江西永丰CaCO3的基本性能和在塑料中的应用效果进行对比分析。结果表明:江西永丰CaCO3的白度不如四川、广西两地,而吸油值比其小;江西永丰的CaCO3填充PP样品的力学性能要比其它两地略高;CaCO3填充PE膜的力学性能、透光度与雾度,三地区的CaCO3难分伯仲。
The representative properties of CaCO3 source in Sichuan and Guangxi and the basic properties of CaCO3 powder and Jiangxi Yongfeng CaCO3 were compared and analyzed in plastic. The results showed that the whiteness of CaCO3 in Yongfeng in Jiangxi Province was not as good as that in Sichuan and Guangxi, while the oil absorption value was smaller than that in Jiangxi. The mechanical properties of CaCO3-filled PP samples in Yongfeng, Jiangxi Province were slightly higher than those in the other two places. , Transmittance and haze, the three regions of CaCO3 difficult to match.
