Ground Calcium Carbonate
Calcium Carbonate is a white colored rock, with specific gravity of 2.5 to 3, and a refractive index of 166, the micronized powder of which is widely used owing to its low price and high capabilities as a filler and extender substance in various industries.Calcium Carbonate contains 55% CaO and 44%CO2, which reacts rapidly withe acids.
Due to minimum oil absorption as well as due to its easy permeability in the resins, this substance is widely used in paint manufacture and through the control of brightness and viscosity adjustment paint could be prevented from becoming mildewed.Calcium carbonate is basically a chemical inorganic compound with chemical formula of CaCO3 whcich is available in various forms, such as limestone, marble, and more. Although they are available in different shapes, but they are chemically similar and differ only physically.
Ground calcium carbonate (GCC) is simply the ground and powdered form of pure calcium carbonate while precipitated calcium carbonate (PCC) is made by hydrating high-calcium quick lime and then reacting the resulting slurry with carbon dioxide.
Applications
Calcium carbonate powder makes and essential improvement on characteristics of the paint and increases the coverage of surface area by the paint.
We manufacture a wide range of different particle size calcium carbonate that can be used for making a different quality of paint. We have also customized our calcium carbonate for some of our strategic partners to ensure the constant quality for their production line.
Calcium carbonate is normally used in paper industry as filler or coating pigment. At present, the Calcium Carbonate is most common in comparison with other papermaking filler materials. The demand for brighter and bulkier paper makes calcium carbonate more interesting than other options.
Selecting the right type of calcium carbonate additive for each kind of paper is the key element to save more costs.
Main profits gained in consequence of using calcium carbonate in paper industry is to create the high level of whiteness, reduce the wood content and environmental footprint, reduce the finished cost and still ensure paper durability.
Calcium carbonate is widely used in construction industry. When added to concrete, calcium carbonate promotes self-compacting characteristics. It creates better workability, high strength and improve the appearance of concrete with a smoother surface.
When it’s used in plaster making, it plays a key role as the final finishing coat on the mortar surface before painting. It helps to create a waterproof and smooth surface.Calcium carbonate can also be used in making pavers, ceramics, renders, grouts and cement.
Calcium carbonate is one of the most commonly used as mineral filler in plastic industry. It’s normally used as plastic compound additive in order to produce opacity and gloss which will improve the surface quality of finished product.
It’s also used in production of flexible and stiff PVC compounds such as wire and cable insulation, latex gloves, extruded pipes and tubes, etc.
When calcium carbonate is used in polypropylene compounds, it will increase the rigidity which is essential for high temperature applications.
Over the recent years, calcium carbonate is also commonly used in rigid packaging as it can improve the quality of packing and save more costs at the same time. It as a plastics additive is approved by FDA, for versatile applications food and medical packaging.
Calcium Carbonate is known as an organic natural fertilizer that reduces the soil acidity degree. It is an essential amendment of plant nutrition which ensure the sustainability of soils after the use of pesticides or heavy rainfalls.
Percentage of purity, consistency and brightness, play the most important roles in the end use and application.
It’s also used to help prevention from spread of various kind of diseases, such as black spot, powdery mildew and blossom. Other advantages of using calcium include in agriculture are protection from heat stress, increment in metabolic functions in plant cells and conducting to a better intake of other nutrients like nitrogen and phosphorus.
Calcium carbonate is also used for animal nutrition. Calcium based additives for cattle and other livestock play an important role in bone strength and growth as well as in general health of animal.
It can increase their resistance to disease, make them easier to digest the food and increase the quality and quantity of their milk.
High-purity limestone together with low grade of acid-insoluble compounds, can be an essential feed for domestic livestock such as sheep, cattle and camels.
Other applications of calcium carbonate include but not limited to glass-making, steel industry, pharmaceutical, leather making, welding, firefighting (preparation of fire extinguishing powders), water and wastewater treatment.
It’s also widely used in other industries such as metallurgy, electrode, chimney desulfurization, oil drilling industry, chemical industries as refractories, in food industries as acidity neutralizers, sculpture making, textile and clothing industries, glass industry, MDF and false ceilings, machine-made carpet production, various types of carpet adhesives and other industries.
New applications of calcium carbonate in more industries are emerging and taking into account of its benefits and advantages, it’s expected to hear more and more about that in future.
