Sepiolite Powder For Decoloring Agent , Absorbent With High Quality
Introduction:
Sepiolite is a kind of chain structure of water rich magnesium silicate clay minerals.Orthorhombic system or monoclinic system, generally the massive, shaped or fibrous assembly.Color is white, light gray, dark gray, brown, rose red, light blue, green.Fresh surface as the pearly luster, after weathering as earthy luster.Hardness is 2 ~ 3, 2 ~ 2.5 g/cm3 density.Have slippery feeling and acerbity feeling, sticky tongue.Sexual crispy dry condition.Low shrinking rate, plasticity is good, is bigger than the surface, strong adsorption.Soluble in hydrochloric acid, light.Sepiolite has decoloring, heat insulation, insulation, corrosion resistance, resistance to radiation performance and thermal stability, etc.Mainly originated from Marine sedimentary - weathering transformation type ore deposit;Also appearing in hydrothermal vein.
