Foshan wire and cable special kaolin manufacturers introduce the physical and chemical properties of heavy calcium:

Foshan wire and cable special kaolin manufacturers and domestic universities and related research The research institution has established a long-term and stable scientific research relationship. With Hubei University of science and technology, Shanghai Cable Institute and other institutions, scientific research institutions have set up a new material R & D and production mechanism integrating "production, learning and research". Following the principle of "quality first, win-win cooperation", the enterprise has established good cooperative relations with major wire and cable enterprises at home and abroad, papermaking enterprises, and water-based coating enterprises. 23. Automatic diagnosis function in the complex and volatile market tide, we uphold the enterprise spirit of quality first and win-win cooperation. Adhere to the quality brand strategy internally and establish a win-win partnership externally. The company will wholeheartedly welcome new and old customers to visit and guide with high-quality products, excellent services and reasonable prices, and use rich experience to collect kaolin. Heavy calcium is an abbreviation of heavy calcium carbonate. Jinan gold testing machine is mainly used in copper alloy strip to detect the tensile strength and elongation of the material. It has good chemical stability. It is a widely used inorganic salt, which is mainly extracted from calcite, limestone, chalk and shell. For this kind of chemical products, the following kaolin manufacturers for wires and cables in Foshan will introduce the physical and chemical properties of heavy calcium

physical properties:

according to different particle sizes, it is divided into: ordinary heavy calcium powder, ultra-fine heavy calcium carbonate, wet grinding ultra-fine calcium carbonate, ultra-fine surface modified heavy calcium carbonate

chemical properties:

the chemical formula of calcium carbonate is CaCO3, and its junction crystals mainly include calcite of complex trihedral hemihedral crystal and aragonite of orthorhombic crystal. Under normal temperature and pressure, calcite is stable and aragonite is quasi stable. At present, calcite is mainly used. The specific gravity of heavy calcium is 2.711. Under normal pressure, calcite is heated to 898 ℃ and aragonite is heated to 825 ℃, which will be decomposed into calcium oxide and carbon dioxide. The inverse mechanical properties of calcium carbonate and all strong acids are more important than other physical properties. Water and corresponding calcium salts (such as calcium chloride CaCl2) are generated, and carbon dioxide is released at the same time; At room temperature (25 ℃), the concentration product of calcium carbonate in water is 8.7 × 1029. The solubility is 0.0014, the pH value of calcium carbonate aqueous solution is 9.5 ~ 10.2, and the pH value of air saturated calcium carbonate aqueous solution is 8.0 ~ 8.6. Calcium carbonate is non-toxic, odorless and irritant. It is usually white with a relative density of 2.7~2.9. Mohs hardness calcite is 3, aragonite is 3.5~4. Calcite has three groups of rhombohedral complete cleavage, and aragonite also has cleavage. The sedimentation volume of heavy calcium carbonate: 1.2~1.9ml/g, and the specific surface area is about 1m2/g; Heavy calcium carbonate has a low oil absorption value of about 48ml/100g due to its large particles, smooth surface and small specific surface area. Non metallic mineral products, heavy calcium, are generally used in coating, papermaking, chemical fertilizer and other industries. Knowing its chemical and physical properties can help consumers prepare for storage and use. Kaolin is a very common mineral in nature. Its formation reason is very simple. It is mainly formed by weathering of feldspar or other silicate minerals in igneous and metamorphic rocks. But now kaolin plays a very huge role in industrial production. Now that the population's demand for resources is growing rapidly, Foshan wire and cable kaolin manufacturers will introduce the main distribution of kaolin in China

distribution in China:

China's Kaolin mineral resources rank among the top in the world. 267 mining areas have been proved, and the proved reserves are 2.91 billion tons, of which: China's non coal kaolin, the resource reserves rank fifth in the world The proved reserves are 1.468 billion tons, mainly distributed in Guangdong, Shaanxi, Fujian, Jiangxi, Hunan and Jiangsu, accounting for 84.55% of the total reserves in China; The reserves of kaolin (kaolinite) from coal bearing formations account for the first in the world, with the proved reserves of 1.442 billion tons, which are mainly distributed in Datong, Huairen, Shuozhou, Zhungeer, Wuda, Huaibei, Anhui, Hancheng, Shaanxi and other places in Shanxi Province, of which the Zhungeer coalfield in Inner Mongolia has the most resources

there are five major kaolin ore producing areas in China:

(1) Jiepai Town, Hengyang County, Hunan Province is rich in mineral resources. The reserves of kaolin, sodium feldspar, potassium feldspar and quartzite reach 200 million tons, and there are nearly 40 mining and mineral product processing enterprises. The single ore reserve of Dapailing mining area (mainly kaolin ore) ranks first in Asia, with 80million tons. The annual mining volume of the town is more than 500000 tons, supplying hundreds of ceramic factories across the country

(2) kaolin in Maoming area. The kaolin deposit in Maoming Basin belongs to sedimentary rock weathering residual subtype deposit, and its sand content such as quartz is greater than 50%, so it is called sandy kaolin deposit. In terms of Genesis, Maoming Kaolin has gone through three stages: weathering residual - handling and self grinding - and then weathering. After air impact, the pointer of kaolin deviates from zero by more than 0.1% of the corresponding pendulum's large impact energy. The kaolin is completely weathered, and the chip is mainly single sheet, with fine particle size. It is mainly the raw material of papermaking coating

(3) Longyan kaolin is a weathered residual kaolin deposit. Because the iron content is less than 0.3%, titanium is less than 0.02%, and contains a certain amount of low-temperature solvent elements (Li2O), it is an ideal raw material for electric porcelain, high-grade household and art porcelain

(4) Suzhou Yangshan kaolin, which is hydrothermal altered kaolin. The chemical composition of Suzhou Yangshan mud with pure texture is very close to the theoretical composition of kaolinite. The content of Al2O3 can be as high as about 39.0%, with white color and fine particles. It is mainly used for catalyst carrier and chemical raw materials

(5) Hepu kaolin: it is a weathered residual kaolin deposit. It is mainly used for building ceramic raw materials

(6) northern coal measure kaolin: it is a sedimentary kaolinite, which is mainly distributed in China's coal areas and can be used for construction, coating, paint and papermaking coating - coal measure soil

the above six production areas account for more than 80% of China's output, and are also mainly representative in terms of resource types. In general, China's kaolin resources are quite abundant, but users should make full use of them when using them
