What is Precipitated Calcium Carbonate?

Sped Up Calcium Carbonate, likewise called limestone and rock powder, is an usual chemical material on the earth. It is a not natural salt mineral. It is alkaline, insoluble in water, and quickly soluble in acid. It normally exists in aragonite, calcite, chalk, sedimentary rock, marble, etc.Calcium is essential to preserve the normal function of human nerve, muscle mass, skeletal system, cell membrane layer and capillary leaks in the structure. The major element of pet bones or coverings is Sped up Calcium Carbonate. Sped up Calcium Carbonate utilized in medical and also edible additives is prepared from calcite. Since it has the impact of calcium supplements after purification, sanitation, purification and also refining, it needs to be used in huge quantities in the process of preparing penicillin, streptomycin and oxytetracycline. It is used as an additive in food to make certain the body’s required calcium consumption, such as eating gum, delicious chocolate, Wahaha, Titan Power Calcium, jelly Xizhilang and also other beverages as a fortifier to meet the body’s need for calcium. According to the various production methods, Sped up Calcium Carbonate can be split into light Precipitated Calcium Carbonate, heavy Precipitated Calcium Carbonate as well as triggered Precipitated Calcium Carbonate. The prep work method of light calcium carbonate (referred to as light calcium) is to calcine raw materials such as sedimentary rock to form lime (the main component is calcium oxide) and carbon dioxide, include water to absorb the lime to form lime milk (the main part is calcium hydroxide), and after that pass into Co2 carbonization of lime milk generates Precipitated Calcium Carbonate precipitate, which is lastly gotten by dehydration, drying and pulverization. Or first of all utilize sodium carbonate as well as Sped up Calcium Carbonate for metathesis reaction to create calcium carbonate precipitate, and after that make it through dehydration, drying out and also pulverization. In daily chemical products such as tooth powder, toothpaste, cosmetics, etc, it can additionally be used in organic synthesis, metallurgy, glass and asbestos manufacturing. The prep work technique of heavy cPrecipitated Calcium Carbonate (referred to as heavy calcium) is to straight squash all-natural calcite, limestone, chalk, shells, etc by mechanical approaches. It is a superb filler and also performance modifier and is widely utilized in plastics, rubber, and so on. Paper, paint, feed, medication, day-to-day chemicals, glass, porcelains as well as various other fields. The preparation method of active Precipitated Calcium Carbonate (referred to as energetic calcium) is to customize the surface area of light calcium or heavy calcium with a surface modifier.
It is a step-by-step type with exceptional performance. Loading help. Response with acid produces co2 gas, which transforms limewater gloomy, as well as is the easiest means to determine carbonate ions.

At the same time, it can make the rubber surface bright as well as fragile.
    4. Layer market It can be utilized as a pigment filler and has the advantages of fineness, uniformity, high whiteness as well as good optical residential or commercial properties. Nano calcium carbonate has steric barrier impact. result. After the paint is made, the brightness of the paint film increases, the gloss is high, and also the concealing power does not lower, that makes it widely popularized and applied in the paint industry Application array: water-based paint and oil-based paint. Application attributes: greatly boost the thixotropy of the system, can dramatically boost the coating bond, scrub resistance, tarnish resistance, improve toughness as well as surface coating, and also has a good anti-settling impact. Partly replace titanium dioxide to minimize prices.
    5. Ink market Scope of application: suitable for lithographic countered printing ink, gravure printing ink, and so on. Application qualities: The ink prepared with Precipitated Calcium Carbonate has good body and thickness, so it has great printing efficiency; good stability; quick drying as well as no adverse effect; as a result of tiny bits, the published product is smooth and the dots are full.

Mix with table salt for pickles. It is used in ice cream making and the sour process to make dextrose. When using polyphosphate as a quality improver for minced meat products, it is best to add a calcium agent to balance calcium and phosphorus (addition amount is 0.5% to 1.5%, calculated as calcium). Add 5% to 10% to the vinyl acetate gum base of gum candy. When making wine, for juices with too high acidity (above 1.5%), calcium carbonate (or potassium carbonate) can be used to remove part of the acid. To remove 0.1% of acid per 100L of grape juice, 66g of calcium carbonate should be added. The acid can be removed after fermentation. An appropriate amount of calcium carbonate can also be added to the compound leavening agent. Prevent hard candy from solidifying. Promote the crystallization of milk chocolate, the dosage is 2.4%. The highest usage in Japan (calculated as calcium): 1% for general food, 2% for gum. It is easy to act with acid, alum and ammonium salt, so attention should be paid to it.
