OVERALL APPLICATIONS OF CALCIUM CARBONATE

1. What is calcium carbonate masterbatch?

The overall calcium carbonate is made of calcium carbonate, the base resin and some resin additives. Calcium carbonate powder (CaCO3) is used in the production of primary calcium carbonate of natural origin. It exists in many forms as calcite, limestone, chalk, marble or aragonite, or in impurities and minerals such as dolomite. For thousands of years, CaCO3 has been one of the most useful minerals for man, in various fields. And by far, one of the biggest users of CaCO3 is probably the filler industry.

2. What forms of calcium carbonate exist?

They usually exist in some form of calcium carbonate, which is usually found as a rock (limestone, chalk, marble, ...). Around the world, they are the main ingredient in shells/shells of shellfish

It is also calcium carbonate that is the cause of the hard water phenomenon that we often know.

3. CaCO3 application:

+ Calcium carbonate has wide applications in industries, especially cement or lime production.

+ In the plastic industry, PVC, uPVC it ​​works as a filler.

+ Calcium carbonate is also a key ingredient in the microporous film used in baby diapers, the paper industry and some construction films due to the nucleation holes around the calcium carbonate particles during the manufacturing process. membrane by biaxial stretching.

Calcium carbonate is known as a "whitening agent" in the glaze of ceramics where it is used as a common ingredient for many glazes in the form of a white powder. When the glaze containing this substance is fired in the kiln, white lime is the flux material in the glaze.

Calcium carbonate is also widely used in a wide range of work and homemade adhesives, sealants and decorative fillers.

+ In addition, it is also applied in the industry: Fertilizer, wastewater treatment, food, medicine, de-acidification.

4. Applications in the plastic industry

a. Ceiling Panels/Frames/Plastic Doors:

Calcium carbonate is widely used in rigid PVC plastic and is most used in the production of plastic pipes and ceiling panels. Using calcium carbonate products increases product durability, better dispersion in plastic chemicals, Optimum product gloss is achieved, improving the production process. Therefore, calcium carbonate is an indispensable material

b. PVC pipes and plastic accessories:

Non-pressurized polyolefin pipes and fittings
Using calcium carbonate products in polyolefin resins will create higher hardness, improve manufacturing processes, shorten lead times and reduce costs. In accessories mainly increase profits.
Pressure resistant PVC pipe
This type usually uses calcium carbonate filler with a low content because to make the pipe product withstand the highest pressure, the product surface is the smoothest and withstands surface impacts.

c. Power cable :

In polyolefin plastic cables, calcium carbonate is increasingly used for the purpose of reducing costs, besides calcium carbonate can be considered as a flame retardant (if properly combined with other resins and additives).

d. Membrane:

Calcium carbonate is widely used in the production of thin films to the production of thick sheets, increasing chemical properties and improving production efficiency. Calcium carbonate reduces production costs, increases hardness, durability in making fillers for products.

e. Breathable plastic film

Using calcium carbonate in the production of evaporative plastic film products with tiny holes has outstanding advantages, especially related to hygiene, calcium carbonate is the active substance in this case, providing membrane with special properties that allow evaporation through a system of tiny pores.

f. Stone powder as filler

Stone powder is also widely used in a wide range of work and homemade adhesives, sealants and decorative fillers.

Ceramic tile adhesives usually contain about 70-80% limestone powder. It is also mixed with mastics for the installation of stained glass windows; as well as a barrier to prevent glass from sticking to the compartments in the high temperature enamelling or painting furnaces.
