活性碳酸钙
【中文】产品特点：1、外观：活性碳酸钙是一种白色粉末，无味、无刺激、折光率低，在空气中稳定。2、活性碳酸钙经过活化处理后，分子结构改变、粒度分布均匀，呈极强的疏水性。3、使用特点是具有白度高、流动性好、光泽度好、分散均匀、填充量大等特点。4、具有比较好的润滑性、流动性、分散性和有机性等化学性质。5、与橡胶、塑料的分子间亲和力强，填充量比普通碳酸钙可多填充2-5倍至数倍。6、吸油值低、白度高，延伸度高，而且其特有的超强金属剥离性和显著的润滑效果还能提高制品表面的光亮度、磨损和抗冲击强度。
【English】Product features: 1. Appearance - activated calcium carbonate is a white powder, odourless, non-irritating, with a low refractive index and stable in air. 2. After activation treatment its molecular structure is changed and the particle size distribution is uniform, giving strong hydrophobicity. 3. It features high whiteness, good flowability, good gloss, uniform dispersion and high loading capacity. 4. It has good lubricity, flowability, dispersibility and organic character. 5. It has strong intermolecular affinity with rubber and plastics, allowing a filling amount 2-5 times or more than that of ordinary calcium carbonate. 6. Low oil absorption, high whiteness and high elongation; its outstanding metal-release property and remarkable lubricating effect also improve surface gloss, wear resistance and impact strength of the finished products.
