Calcium carbonate powder use
Three types of rocks containing calcium carbonate are used in the calcium carbonate powder industry. These three types of rocks are limestone, gypsum and dolomite. Limestone and gypsum are both forms of calcium carbonate and dolomite is a combination of calcium carbonate and magnesium. All contain impurities such as clay, but some rocks are more than 97% pure. Limestone and other products derived from it are widely used in the construction industry and neutralize acidic compounds in various fields.
In the chemical industry, large quantities of limestone at about 1500 Kg are used to produce calcium oxide, known as sunflower cholesterol.
Water can be added to lime to form calcium hydroxide. This process is known as "slippage". Solid calcium hydroxide is known as lime or hydrated lime, and water-soluble is known as slaked lime.
The term lime is often used to cover lime, lime (hydrated lime) and slaked lime. For specific use, select Suitable is made of four types of limestone, raw lime, lime or slaked lime. In many applications, lime reacts faster than limestone but is more expensive because it requires high temperatures to produce it from limestone.
Calcium carbonate applications
Calcite or calcium carbonate is a naturally occurring mineral. can be changed Its industrial application depends on properties such as composition, particle size and shape, specific gravity, hardness and color. The main use of lime and limestone is in the construction and cement industry. It is also used in chemical, metallurgical and agricultural industries.
Iron smelter and metallurgy industry
It is one of the most important uses of calcium carbonate in the metallurgy industry and melting of various metals such as iron. In the metallurgical industry and metallurgy, calcium carbonate is used as a melting aid and purifier in melting furnaces.
Construction materials and construction
Calcium carbonate is vital to the construction industry, both as a building material in its own right (eg marble), and as an ingredient in cement. This material plays a role in the manufacture of mortars used in gluing bricks, concrete blocks, stones, roof shingles, rubber compounds and tiles. Calcium carbonate decomposes to form carbon dioxide and lime, an important ingredient in the manufacture of steel, glass and paper. Due to its antacid property, calcium carbonate is used in industrial environments to neutralize acidic conditions in soil and water.
Paper, plastic, paint and cover
Calcium carbonate is the most widely used mineral in the paper, plastic, paint and coating industries, both as a filler - and because of its special white color - as a coating pigment. In the paper industry, it is valued worldwide for its high brightness and light scattering properties and is used as an inexpensive filler to make light matte paper. The filler is used at the end of paper making machines and the calcium carbonate filler makes the paper shiny and smooth. Calcium carbonate as a developer can represent up to 30% of the weight in the paint. Calcium carbonate is also used as a filler in adhesives and sealants.
