Physical and Chemical Properties | Sepiolite is a kind of hydrous and magnesium-rich silicate clay mineral with layered chain structure. Orthorhombic or monoclinic system, generally in the form of a block, soil-like or fibrous assembly. The color is white, light gray, dark gray, yellow-brown, Rose Red, light blue-green. The fresh surface is pearl luster, and after weathering, it is earthen luster. Hardness 2~3, density 2~2.5g./cm3. With sliding and astringent feeling, sticky tongue. It is brittle in dry state. Low shrinkage, good plasticity, large specific surface, strong adsorption. Soluble in hydrochloric acid, light weight. Sepiolite also has decolorization, heat insulation, insulation, corrosion resistance, radiation resistance and thermal stability. It is mainly produced in the transformation of a marine sedimentary weathering type deposits; Also appear in the hydrothermal veins. |

It is mainly produced in the transformation of a marine sedimentary weathering type deposits; Also appear in the hydrothermal veins.
for sedimentary deposits, the vast majority of the use of open-pit mining method; And for hydrothermal deposits generally use underground mining method. See "phosphate rock" for general process flow ". The mineral processing methods include wet and dry methods, and the wet method is the main method. The mineral processing technology is usually based on physical methods, supplemented by a comprehensive mineral processing process that is conducive to the separation of chemical agents. The general principle of mineral processing is as follows: raw ore-hand-selected one plus dispersant stirring one screening two times one plus dispersant stirring one sorting one plus flocculant stirring one mechanical classification-concentrate pulp classification one three grade concentrate pulp one plus filter aid mixing one filter cake drying one crushing one final product.
sepiolite is widely used. Fillers and reinforcing agents used in the chemical industry for rubber, foaming and decolorizing agents for plastics, electrolytic membrane modifiers for the production of caustic soda, thickeners and thixotropic agents for daily cosmetics, manufacturing paints, various types of shampoos, toothpaste, lipstick, ointment, soap and catalyst carrier, used in agriculture for soil improvement, breeding liquid carrier, pesticide carrier, seed pellicle, animal feed growth promoter, feed adhesive, carrier of feed ingredients and urea-calcium-potassium chloride series compound fertilizer; Can also be used as excipients in the pharmaceutical industry, drug abuse and decolorizing agents in the food industry, deodorant and drug abuse agents in the environmental protection industry, catalysts and suspending agents for light textile industry, building sound insulation and thermal insulation materials, interior and exterior architectural coatings, drilling mud materials, grounding materials for power systems, welding electrode accessories, casting sand Binder, special ceramic components for rocket and satellite, special Paper, oil refining decolorizing agents and filters, wine and sugar molecular sieves, cigarette filters, engraving crafts and accessories.
packing to be strong, clean, each bag net weight (25±0.5)kg; The use of woven bag lined with plastic bag packaging. During storage and transportation, the bag shall be protected from rain, moisture and breakage, and mixed with pesticides, chemical fertilizers and chemicals shall be strictly prohibited.
