Chrome oxide green
Chrome oxide green by chromic acid, sodium or potassium dichromate and sulfur etc. After the high temperature roasting. Or by the thermal decomposition of ammonium dichromate. High temperature resistant, light resistance, resistance to all kinds of chemicals. The pure products of infrared reflection close to natural chlorophyll mohs hardness close to alumina (Al2O3), second only to diamond. Insoluble in water, acid and organic solvents, slightly soluble in concentrated sodium hydroxide solution, soluble in hot, hot perchloric acid solution of sodium bromate solution or boiling sulfur phosphorus mixed acid. Light, atmosphere, and corrosive gases (H2S, SO2, etc.) is extremely stable, excellent weather resistance. Stability when it is heated, it is of high quality refractory materials. Chromium trioxide is mainly used in metallurgy, pigment, grinding and polishing, fire-proof material and developed new melt spray paint, etc.
Chrome oxide green
1, in the building materials industry is mainly used in colored cement, color cement tile, color cement tile, glazed tile and floor tile, color mortar, color asphalt concrete, terrazzo, Mosaic tiles, artificial marble and metope paint, etc.;
2, used in a variety of coatings to protect material and color, external walls including waterborne coatings, powder coatings, etc.; It also can be used in paint including epoxy resin, alkyd, amino and so on all kinds of primers and paint; Can also be used for toy paint, decoration paint, furniture paint, electrophoresis paint and enamel. Iron red primer has the antirust function, can replace expensive red lead paint, save non-ferrous metals.
3, used for plastics coloring, such as thermosetting plastics and thermoplastic plastics, coloring and rubber products, such as automobile inner tube, inner tube, bicycle inner tube, etc.
4, used for advanced fine grinding materials, used in precision hardware instruments, such as optical glass polishing. High purity is the main basic material of powder metallurgy, used for smelting various magnetic alloy and other advanced alloy steel. By ferrous sulfate, iron oxide yellow or waste iron mixed by high temperature calcination, or directly from the liquid medium is made.
