Several Factors Influencing the Whiteness of Light Calcium Carbonate |
In the production of light calcium carbonate, most enterprises pay attention to the strict selection of lime materials to control the whiteness of its products, which is undoubtedly the main factor to ensure the production of light calcium carbonate that meets the user's needs and meets the whiteness standard. However, the influence of the following factors on the whiteness of light calcium carbonate cannot be ignored: fuel quality, quicklime quality, lime kiln gas dust, drying system flue gas and production environment. If these factors are not included in the process control or are not strictly controlled or even out of control, it will be difficult for the produced superfine light calcium carbonate to reach the qualified product indicators or meet the needs of users. Therefore, to ensure and improve the whiteness of light calcium carbonate, we should not only start with the screening of lime, but also comprehensively and comprehensively control the relevant factors that affect the whiteness of light calcium carbonate in various production processes. Here are some conditions that restrict the whiteness of light calcium carbonate: 1. Quality of raw materials 1. Limestone 2 Fuel 2. Quicklime 3. Gas and dust of lime kiln 4. Flue gas of drying system |

The prospect of light calcium is very broad |
Light Calcium Carbonate is also called Precipitated Calcium Carbonate (PCC). Light calcium carbonate is made by chemical processing. Because its sedimentation volume (2.4-2.8 mL/g) is larger than that of heavy calcium carbonate produced by mechanical method (1.1-1.9 mL/g), it is called light calcium carbonate. As the raw material of chemical industry, light calcium carbonate is not only an excellent filler, but also an ideal modifier, and is widely used in rubber industry, plastic industry, paper industry, building materials industry, etc. There are many manufacturers of light calcium carbonate in China, some of which are ordinary light calcium carbonate or ordinary heavy calcium carbonate with large particles and uneven particle size distribution. Compared with ordinary calcium carbonate, ultrafine calcium carbonate and active calcium carbonate have greater particle size and surface activity. At present, there is a very broad market for the development and production of high-grade light calcium carbonate and active calcium carbonate products in China, which has huge social and economic benefits. |

Application of light calcium carbonate in rubber and plastic industry |
1. Light calcium carbonate is widely used in rubber products, such as tires, rubber hoses for conveyor belts, adhesive tapes, medical rubber products, etc., which can reduce rubber consumption, reduce costs, and also play a role in reinforcement and semi. The application of light calcium carbonate in plastics can reduce the consumption of organic raw materials, reduce costs, improve the stability, hardness and rigidity of plastics, improve the processing performance of plastics, improve the heat resistance of plastics, and improve the astigmatism of plastics. Second, light calcium carbonate can play a skeleton role in plastic products, which has a great impact on the dimensional stability of plastic products, can improve the hardness of products, and can also improve the surface gloss and surface finish of products. Adding calcium carbonate to general plastic products can improve heat resistance. Because the whiteness of calcium carbonate is more than 90%, it can also replace expensive white pigments and play a whitening role. |

Light calcium carbonate is called light calcium for short, which is widely used |
Light calcium is light calcium carbonate, also called precipitated calcium carbonate, or simply light calcium. It is made by burning limestone and other raw materials to produce lime and carbon dioxide, adding water to digest lime to produce lime milk (mainly calcium hydroxide), adding carbon dioxide to carbonize lime milk to produce calcium carbonate precipitation, and then dehydrating, drying and crushing. Or, sodium carbonate and calcium chloride undergo double decomposition reaction to generate calcium carbonate precipitation, which is then dehydrated, dried and crushed. Light calcium is white powder. Odorless. The specific gravity is about 2.71. It decomposes at 825~896.6 ℃. Melting point 1339 ℃. There are amorphous and crystalline forms. The crystalline forms can be divided into orthorhombic and hexagonal systems, which are columnar or rhombic. Insoluble in water and alcohol. It is soluble in acid and emits carbon dioxide at the same time, showing exothermic reaction. It is also soluble in ammonium chloride solution. Stable in the air, with slight moisture absorption capacity. It can be used as filler in rubber, plastic, paper making, paint and ink industries. It is widely used in organic synthesis, metallurgy, glass and asbestos production. It can also be used as a seed agent for industrial wastewater, an antacid for gastric and duodenal ulcer disease, an antidote for acidosis, an agent to eliminate SO2 in waste gas containing SO2, an additive for dairy cattle feed, and an anti sticking agent for linoleum. It can also be used as raw material for tooth powder, toothpaste and other cosmetics. |
