超細硅灰石(XWS系列) Superfine Wollastonite (XWS Series)
硅灰石屬于偏硅酸鹽類,通常呈束狀、放射狀或纖維狀集合體,是一種無毒無害的產品,超細硅灰石粉具有遮蓋力好、耐候性好,可替代鈦白粉、鋅鈦白、立德粉、沉淀硫酸鋇等顏料,用在建筑涂料、工業涂料等高檔涂料中,具有**的抗腐蝕性和耐用性。
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.
