碳酸钙 (CAS No.471-34-1)
- 物化性质
- 白色微细粉末，无味。不溶于水，易溶于酸，密度约为2.7-2.9 g/cm³，加热至约825℃分解为氧化钙和二氧化碳。具有粒径小、比表面积大、表面亲油疏水等特点。
- 技术参数
- 在塑料工业中可改善母料流变性，提高成型性，具有增韧补强作用，提升弯曲强度和弹性模量。 在油墨中分散性和透明性优异，光泽度高，油墨吸收性好，干燥快，适应高速印刷。 在橡胶中易混炼分散，混炼后胶质柔软，表面光滑，提高延伸性、抗张强度和撕裂强度。 在涂料中显著改善体系触变性，提高附着力、耐洗刷性、耐沾污性及表面光洁度。 在造纸中提高纸张松密度、表观细腻性和吸水性，并可调节卷烟纸燃烧速度。

Product Name:Calcium carbonate
English Name:Calcium carbonate
CAS No.:471-34-1
Aliases:Nano calcium carbonate
Molecular Formula:CaCO3
Physical Properties:White fine powder, odorless. Insoluble in water, readily soluble in acids. Density approx. 2.7-2.9 g/cm³. Decomposes into calcium oxide and carbon dioxide at about 825°C. Characterized by fine particle size, large specific surface area, and lipophilic-hydrophobic surface.
Uses:Widely used as a filler and modifier in plastics, rubber, coatings, inks, and papermaking industries. In plastics, it improves rheology and moldability, enhancing flexural strength, heat deflection temperature, and dimensional stability. In rubber, it acts as a reinforcing and filling agent, improving elongation and tensile strength. In inks, it provides excellent gloss, dispersion, and fast drying. In coatings, it improves thixotropy, adhesion, and scrub resistance.
Technical Specifications:
In plastics, it improves the rheology of masterbatches and moldability, providing toughening and reinforcing effects, increasing flexural strength and elastic modulus.
In inks, it exhibits excellent dispersion and transparency, high gloss, good ink absorption, and fast drying, suitable for high-speed printing.
In rubber, it is easy to mix and disperse, giving soft compound surfaces and improving elongation, tensile strength, and tear strength.
In coatings, it significantly improves thixotropy, enhancing adhesion, scrub resistance, stain resistance, and surface smoothness.
In papermaking, it increases bulk, surface smoothness, and water absorption, and can regulate the burning rate of cigarette paper.
