摘要
选取国内市场上几种常见的碳酸钙粉体,通过电镜观察晶型、形貌、粒径,测试其比表面积、吸油值、黏度、振实密度等基本性能,介绍了纳米碳酸钙各项性能指标的作用及相互间的关系。并总结了纳米碳酸钙各项指标对硅酮密封胶性能的影响。
Several common calcium carbonate powders on the domestic market are taken. The crystal form, morphology and particle size are observed by electron microscope and their basic properties such as specific surface area, oil absorption,viscosity and tap density are tested. This article introduces the function and relationship between each performance index of nano calcium carbonate and summarizes the influences of nano carbonate on the performance of silicone sealants.
