改性硅灰石

硅灰石 Wollastonite

硅灰石化学式CaSiO3，是一种稀有矿物资源，是特的纤维状结果的无机粉体材料，具有良好的物理和化学性质。硅灰石有很高的白度，有的耐热性和介电性，有很低的吸水率和吸油率，有较好的耐碱性和良好的助熔性，有低生物耐受性、无嗅等特点，是一种理想的白色补强功能性材料。

  Wollastonite (CaSiO₃) is a rare mineral resource of unique acicular structure with goodphysical and chemical properties. The main features of wollastonite are high brightness, high heat resistance and dielectric properties, low moisture and oil absorption rate good alkali resistance, non-hazardous and so on. It’s very good reinforcement filler.

硅灰石矿纤（XWA系列） Wollastonite Mineral Fiber （XWA Series）

硅灰石是的成针状纤维结构的白色填充料，其长径比可达到20:1，广泛的应用在各种塑料制品中，可以提高制品的电绝缘性、冲击强度、抗拉强度，改善制品的线性拉伸和模收缩率，可以部分或完全取代传统玻纤，起到明显的增强补强作用。

Wollastonite is the only a pure white filling material with acicular fiber structure, the aspect ratio can up to 20:1, it was widely used in plastics, It can improve the electric insulation, impact strength and tensile strength of products, and it can improve the linear stretching and die shrinkage of products. It can replace the traditional glass fiber partially or completely to offer strengthening significantly.

超细硅灰石（XWS系列） Superfine Wollastonite (XWS Series)

硅灰石属于偏硅酸盐类，通常呈束状、放射状或纤维状集合体，是一种无害的产品，超细硅灰石粉具有遮盖力好、耐候性好，可替代钛白粉、锌钛白、立德粉、沉淀硫酸钡等颜料，用在建筑涂料、工业涂料等涂料中，具有的抗腐蚀性和性。

Wollastonite is a metasilicate mineral of unique acicular structure with good physical and chemical properties, which can replace titanium dioxide, zinc titanium dioxide, lithopone, precipitated barium sulfate and other pigments. It has good hiding rate, good weather and corrosion resistance when used in paint and coatings.

 can be used to enhance the adhesion of coating, which can make the coating has better mechanical strength, persistence, and weather resistance to prevent the cracking.
