Product Introduction:
Calcium carbonate, also known as limestone and rock flour, is a chemical commonly found on earth and is an inorganic salt mineral. It is alkaline, insoluble in water, and readily soluble in acids.
Calcium carbonate is produced by integrating calcium ions with carbonate ions and also is, for that reason, both a calcium salt as well as a carbonate. It takes place naturally within rocks such as aragonite, calcite, chalk, sedimentary rock, marble, and also limestone.
This product is one of the rubber market’s primary dental fillings as well as reinforcing representatives. Light as well as heavy calcium are commonly used in the rubber industry to meet the varied needs of the rubber industry. Click here to learn the difference between light and heavy calcium and their applications.
As an experienced calcium carbonate manufacturer, Look Chemical produces and sells various calcium carbonate raw materials in various grades. With excellent quality and professional service, you can save time and money.

Product Usage:
Calcium carbonate powder is an important inorganic chemical product widely used in the rubber, plastic, paint, paper, food, cosmetics, pharmaceutical, and daily chemical industries.
The role of calcium carbonate in industrial production
- Rubber industry
- Calcium carbonate is one of the earliest and also biggest fillers made use of in the rubber industry. It can be filled in large quantities in rubber to raise the volume of the item and hence conserve costly natural rubber for price reduction functions.
- It can be filled right into rubber to obtain a greater tensile toughness, abrasion resistance, and tear stamina than pure rubber vulcanization and also has a significant strengthening effect on natural as well as artificial rubber, as well as changing the consistency.
- Plastics sector
- Calcium carbonate can play a skeleton duty in plastic items, which has an excellent result on the security of the dimension of plastic items, can enhance the hardness of the items, and also can likewise enhance the surface gloss and emerge monotony of the products.
- Adding calcium carbonate as a whole plastic items can improve warmth resistance, as the whiteness of calcium carbonate is over 90%; it can likewise replace expensive white pigments to play a specific role in whitening.
- Paint market
- The amount of it in the paint market is huge. In the thick paint dosage of more than 30%, it is essential for the skeletal system, phenolic magnetic paint 4-7% phenolic great pattern crease repaint greater than 39%.
- Water-based paint market
- The application in the water-based paint sector, which is more comprehensive, can make the paint not sink, simple to spread, excellent gloss, and other features, in the water-based paint dosage of 20-60%.
- Other
- In addition, calcium carbonate plays an essential function in the paper sector to ensure the strength of paper, whiteness, and also inexpensive. In the cord market, it can play a function in insulation.
The duty of calcium carbonate in cosmetics
- Including nano calcium carbonate to cosmetic items can make the item fragile and also smooth, improving the performance and item quality. It is made use of as an additive to make establishing powder, which can eliminate the base powder’s brightness, shield the skin’s attachment, and also has modest oil absorption and anti-sweat result.
- It can also be made use of as a toning powder, which does not aggravate the skin, has constant shade, and also has a particular protection power. Current trends in cosmetics in the house as well as abroad are restorative, practical, and natural.
Calcium carbonate in food
- Calcium carbonate for food use: used in food processing as a bulking agent, nutritional fortification agent, flour improver, anti-caking agent, leavening agent, PH regulator, etc.
- Food grade calcium carbonate is easily absorbed, odorless, biologically effective, and has few side effects. It can be widely used in the food, pharmaceutical, and health care industries.
- In addition to being a nutritional fortifying agent, it can also be used as an alkalizing agent, dough conditioner, or anti-caking agent. It is widely used in food, pharmaceuticals, and health food.
In addition, when used as a filler, calcium carbonate modified by activation improves dispersibility and fluidity, avoids agglomeration and lumping, and significantly improves the appearance of the product surface.
Hefty Calcium Carbonate and Light Calcium Carbonate:
Relying on the manufacturing process, there are hefty and light calcium carbonates.
- Heavy calcium carbonate.
- Hefty calcium carbonate (shortened as heavy calcium carbonate) is generated by mechanical methods (utilizing Raymond mills or other high-pressure mills) by straight crushing all-natural calcite, sedimentary rock, chalk, shells, and so on.
- Hefty calcium carbonate is called bicarbonate due to the fact that its clearing up volume (1.1-1.9 mg/L) is smaller than light calcium carbonate (2.4-2.8 mL/g).
- Light calcium carbonate.
- Light calcium carbonate, also recognized as precipitated calcium carbonate, is produced by calcining resources such as sedimentary rock to generate lime (the major element is calcium oxide) and carbon dioxide, then adding water to absorb the lime to produce lime milk (the major element is calcium hydroxide), after that carbonizing the lime milk with co2 to produce calcium carbonate debris, and lastly dehydrating, drying and crushing.
- Light calcium carbonate is called light calcium carbonate because of its larger sinking quantity than hefty calcium carbonate.
Applications of calcium carbonate in rubber:
Heavy calcium carbonate is primarily utilized as a filler in the rubber market yet can also be made use of as a coloring agent, separating agent, as well as mold launch representative. It can raise the tightness of the rubber immediately the vulcanization and is inexpensive as well as appropriate for shoe heels, soles, floor covering, hoses, as well as molded, extruded, and also frothed rubber items.
Light calcium carbonate has semi-reinforcing residential or commercial properties as well as is generally used as a white reinforcing filler for rubber. Light calcium carbonate is very easy to spread in the rubber, which can improve the rubber’s tensile toughness, tear strength, as well as abrasion resistance, and its physical properties are somewhat much better than those of heavy calcium carbonate rubber. Light calcium carbonate is widely utilized in rubber items, such as conveyor belts, pipelines, rubber sheets, rubber towels, rubber footwear, as well as medical rubber products.
