Calcite Products: Widely Used Mineral Treasures

Calcite Products: Widely Used Mineral Treasures

Calcite, as a common calcium carbonate mineral, plays an important role in many fields due to its diversified characteristics and wide distribution. Relying on high quality calcite resources, our company is committed to providing high quality calcite products for various industries to meet the needs of different customers.

I. Characteristics of calcite

Crystal form and appearance: The crystal shape of calcite is rich and diverse, and its aggregate can appear as cluster crystal, granular, massive, fibrous, bell emulsion and earth and other forms. When tapping calcite, many rhombic body fragments can be obtained, which is also the origin of the name "square solution". Its color will vary according to the impurities it contains, usually white or colorless, and colorless transparent calcite is called Iceland SPAR, with a double refractive index of up to 0.172, through it can see the object of double image, which makes Iceland SPAR become an important optical material.

Chemical composition and structure: Calcite belongs to the tripartite crystal system, common intact crystal, diverse morphology, different polymerization up to 600 kinds, mainly in parallel development of column, plate and various states of rhombohedral or complex tripartite partial trigonometaloid. It often contains Mn, Fe, Zn, Mg, Pb, Sr, Ba, Co and other analogues, when these elements reach a certain content, can form manganese calcite, iron calcite, zinc calcite, magnesium calcite and other varieties, in addition, There may also be brucite, dolomite, iron hydroxide and oxide, sulfide, quartz and other mechanical impurities in the crystal.

II. Application of calcite in packing

Rubber industry: Calcite powder as a capacifier, widely used in the rubber industry, can save the amount of natural rubber or synthetic rubber, reduce costs. The amount of addition is generally between 10% and 60%, good dispersion, can be mixed with rubber, can also be mixed with other additives, help to improve the processing performance of rubber, play a reinforcing or semi-reinforcing role, and can adjust the hardness of rubber. The calcite powder for rubber industry provided by our company is of high quality, with CaCO₃ content above 99%, sieve residue (below 44um) only 0.2%, oil absorption rate of 70ml/100g, which is the ideal choice for rubber production.

Plastic industry: As a filler, calcite powder has many advantages in the production of plastic products. It can improve the dimensional stability, hardness and rigidity of plastic products, change the processing performance, and improve the heat resistance, flame retardant and insulation, but also improve the astigatism. The calcite powder supplied by our company can help plastic products to achieve significant improvement in performance and quality.

Paper industry: Paper industry is one of the main application fields of calcite powder. Our company provides calcite powder for paper making, CaCO₃ content is more than 98.5%, whiteness is 90%, particle size is 325 mesh. In paper production, adding 10%-40% calcite powder can ensure the strength and whiteness of paper and effectively reduce the cost. In paper coating, calcite powder under neutral or alkaline conditions, the filling proportion in white color varies according to different paper types, such as advanced copperboard paper is 5%-20%, intermediate copperboard paper is 10%-25%, coated paper is 20%-80%, stamp paper is 15%-70%, Matte copper paper can reach 70%-100%. Calcite powder in the papermaking process, not only can provide high whiteness, but also can adjust the absorption of ink, with good hiding power and optical properties.

III.  Application of calcite powder in building materials

Coating: Calcite powder as a body pigment, because of its fine particle and good dispersion, become one of the more dosage of filler. In oil-based coatings, it is the main component of primer and putty, accounting for 50%-70% of the total amount; In the original paint, the raw material can be thickened and thickened, filling and leveling, the dosage can reach 30%-70%; In anti-rust coating, the amount of up to 48%. The calcite powder produced by our company can provide excellent performance and quality guarantee for coating products.

Glass: Callite powder as the ingredient of glass production, our company strictly controls the quality of our products, the CaO content of grade 1 is more than 54%, Fe₂O₃ content is less than 1.5%; The CaO content of grade 2 is more than 47%, and the Fe₂O₃ content is less than 0.2%, which can meet the strict requirements of glass manufacturers for raw materials and help to produce high-quality glass products.

Ceramics: Calcite powder is used as flux in ceramic production. The calcite powder for ceramic provided by our company has a CaCO₃ content of more than 96%, MgCO₃ content of less than 1%, Fe₂O₃ content of less than 0.25%, SiO₂ content of less than 2%, and SO₃ content of less than 0.1%, which can provide good fluxing effect for ceramic firing. Improve the quality and performance of ceramic products.

Composite material: In the new calcium plastic composite material with wood, plastic and paper properties, the addition of calcite powder makes the material have new properties, such as heat resistance, corrosion resistance, cold resistance, sound insulation and shock proof, easy processing, etc. Our company with high quality calcite powder products, actively promote the development of calcium plastic composite material industry, to meet the market demand for new materials.

IV. Application of calcite powder in other fields

Pharmaceutical industry: Calcite powder is one of the important components of pharmaceutical industry medium, but also the buffer of microbial fermentation and filler of some tablets, providing a key auxiliary role for drug production.

Food and feed: as a food additive, the general amount of calcite powder is 2%, which can ensure the intake of essential calcium for human body; In toothpaste, a large amount of calcite powder can be added as a rub, the amount of addition reached 10%; At the same time, calcite powder is also an important additive in livestock and poultry feed, which can promote the growth of livestock and poultry.

Printing inks, putty, sealing waxes and adhesives: Calcite powder is used as a capacifier in these areas, which can effectively reduce costs and improve product performance and quality.

Our company relies on advanced production technology and strict quality control system to ensure the stable and reliable quality of calcite products produced. We focus on providing quality calcite products and solutions to customers in various industries, whether it is rubber, plastic, paper, building materials or other fields, we can meet your needs. Choose our calcite products, is to choose excellent quality and professional service, let us join hands to create a better future!
