Vietnam Calcium Carbonate Powder (CaCO3) is a very important substance in today’s modern industry with a multitude of features and useful support for advanced industry.
So why is CaCO3 so magical ???
Vietnam Calcium Carbonate is a chemical compound with the chemical formula CaCO3. It is estimated that about 5% of the Earth’s crust is some form of calcium carbonate, which is commonly found in the form of rocks (limestone, chalk, marble …) all over the world, as the main ingredient. shells of clams, snails or snail shells. It is the main cause of hard water.
Vietnam Calcium Carbonate has many practical applications in life and in manufacturing due to its popularity and cheapness. Here are some applications of CaCO3 (also known as limestone, stone powder, light powder …):
1. Vietnam Calcium Carbonate Powder (CaCO3) is mainly used in the construction industry such as construction stone, marble or as a component of cement or from it produces lime. In limestone powder often includes magnesium carbonate.
2. Vietnam Calcium Carbonate Powder (CaCO3) is widely used in the paint industry, Calcium Carbonate is considered as the main filler. The fineness and size distribution of calcium carbonate particles affect the opacity of the coating process. In addition, Calcium Carbonate has high brightness, low oil absorption, good dispersion, environmental resistance, low abrasion resistance, stable pH, enhanced environmental corrosion resistance and improved viscous products
Vietnam Calcium Carbonate Powder (CaCO3) is used a lot in the paint industry (decorative paint), it contributes to increase the optical ability of the paint and the weight of the paint. Vietnam Calcium Carbonate Powder (CaCO3) can use up to 60% content in paint production.
3. Applications in the plastic industry
a. Ceiling panel / Frame / Plastic door:
Vietnam Calcium Carbonate Powder (CaCO3) is widely used in rigid PVC resin and is most widely used in the production of plastic pipes and ceiling panels. Use of Calcium Carbonate product increases product durability, dispersion in better plastic chemicals, optimal product gloss, improved production process. Therefore, Calcium Carbonate Powder (CaCO3) is an indispensable raw material
b. PVC pipes and plastic accessories:
Polyolefin pipes are not pressure resistant and fittings
Using Calcium Carbonate Powder (CaCO3) in polyolefin resin will create higher hardness, improve production process, shorten production time and reduce costs. In accessories mainly increase profit.
PVC pipes are under pressure
This type often uses Calcium Carbonate Powder (CaCO3) filled with little content because to make the pipe product withstand the highest pressure, the surface of the product is the smoothest and withstand the impact of the surface.
c. Power cable :
In polyolefin plastic cable, Calcium Carbonate Powder (CaCO3) is increasingly used for the purpose of reducing costs, in addition, Calcium Carbonate Powder (CaCO3) can be considered as a flame retardant. suitable for plastics and other additives).
d. Membrane:
Vietnam Calcium Carbonate Powder (CaCO3) is widely used in the production of thin films to the manufacture of thick sheets, increasing the chemical properties and improving the production productivity. Calcium Carbonate Powder (CaCO3) reduces production costs, increases hardness, and increases durability as fillers for products.
e. Plastic film evaporates
Using Calcium Carbonate Powder (CaCO3) in the production of plastic film vaporizing with tiny holes has special advantages related to hygiene, Calcium Carbonate Powder (CaCO3 ) is the active substance in this case, providing the membrane with special properties that allow evaporation through the tiny pore system.
g. Blow Molding
When using Calcium Carbonate Powder (CaCO3) in the manufacture of cast products, the hardness and durability will be improved leading to cost savings.
4. Calcium Carbonate powders are also widely used in a wide range of work and homemade adhesives, sealants and decorative fillers. Ceramic tile adhesives typically contain about 70-80% limestone powder. It is also mixed with coolers to install discolored glass windows, as well as a color barrier to prevent glass from sticking to oven compartments during high temperature glaze or paint. .
5. Water treatment agent
– Absorb toxic gases that accumulate in the pond bottom such as NH3, H2S, CO2 . . . and acids in water, reduce the proportion of toxic and heavy metals in the pond.
– Decomposition of algae, dirty suspended substances in the pond, help balance the water environment, stabilize the pH .
– Stable water color, limits scum, purifies water, increases dissolved oxygen (DO) in water.
– Limiting pathogens, harmful bacteria in water, glowing bacteria in the pond . . .
6. Calcium Carbonate Powder (CaCO3) is also widely used in medicine as a low-cost calcium dietary supplement and a de-acidifying agent. It is also used in the pharmaceutical industry as a base for pills made from other pharmaceuticals.
7. Calcium Carbonate powder is known as “whitening agent” in glazing ceramics. When the enamel containing this substance is heated in a furnace, white lime is the molten material in the enamel.
It is also commonly referred to as chalk because stone powder is a major component of marker chalk. Today’s chalks can be either made from Calcium Carbonate or gypsum, Calcium Sulfate hydrated CaSO4 ยท 2H2O.
