What is calcium carbonate powder?
Calcium carbonate powder
Calcium carbonate is an exceptional mineral. Calcium carbonate, or CaCo3, contains more than 4% of the Earth’s crust and is found all over the world. Calcium carbonate is one of the most widely used materials known to humans. It can be produced artificially, and is also available in egg shells and animal membranes such as snails and crabs. The pearl is also calcium carbonate. Calcium carbonate is extracted from the mine for use in industry. Pure calcium carbonate can be produced from marble, or it can be produced by passing carbon dioxide through a solution of calcium hydroxide.
Calcium carbonate is converted into lime by the loss of CO2, which is used in construction works, in the iron extraction industry and in the production of steel as a melting aid and for the preparation of calcium carbide. Lime in agriculture is also used to correct soil and adjust its PH. Calcium carbonate is used in ceramic and tile industries, especially in the glazing industry. Due to the formation of the eutectic, the melting point of the set is lowered and when applied in glaze, the coefficient of thermal expansion of the glaze is lowered. Calcium carbonate is one of the most used minerals used in the paper industry, plastics, paints and coatings as fillers and coatings (due to its special white color). The paper industry is valued worldwide for its high brightness and light dispersion, and is used as a cheap filler to illuminate the surface of the paper lint.
Calcium carbonate (PCC or Precipitated Calcium Carbonate)
This product is in fact the complete form of micronized calcium carbonate (GCC) because the morphology of the GCC crystals is improved throughout the process. For this reason, the interest in using it to increase product quality has increased.
The process of production of calcium carbonate carbonate by direct calcification of lime milk is carried out as follows:
– Extraction of high-purity ore
– Mining and crushing to the required dimensions,
– Removing some impurities from rock,
– Calcination in the furnace up to 1850 degrees Fahrenheit,
– Increased water to lime to produce lime milk,
– remove impurities from lime milk,
– Mixing of lactic acid with carbon dioxide, formation of calcium carbonate and its degradation,
– Remove impurities from the pulp,
– If needed, increase the percentage of solids in the pulp,
– If necessary for the production of dry crop dehydrating, drying, milling and packaging.
Calcium Melting or Micronized (GCC or Ground Calcium Carbonate)
GCC is produced directly from the extraction of pure mineral ores. The production process involves cooking, removing waste materials with garbage, grinding and grinding, dimensional classification and drying. The production method of this calcium carbonate is much simpler and less costly than calcium carbonate.
