Ground Calcium Carbonate

model GCC

Product Description

Calcium carbonate is an extremely important inorganic salt raw material, serving as one of the most commonly used fillers in manufacturing and processing industries. It finds widespread applications in industries such as rubber, plastics, papermaking, ink, paints, construction materials, agriculture, and fruit cultivation.

Ground calcium carbonate, depending on the different grinding principles used in its production, exhibits varying particle shapes and physical properties. Its particle structure primarily consists of irregular particles, and the differences in fineness and shape contribute to variations in bulk density.

Currently, there are two main methods for industrial production of ground calcium carbonate: dry process and wet process. The dry process is mainly employed for industries such as rubber, plastics, and coatings, while the wet process is more suitable for papermaking. Our factory adopts the former method, the "dry production process."

Given the diverse and distinctive characteristics of various calcium carbonate products, users can select the most suitable specifications based on their application environment or individual needs to achieve the desired outcomes.

Specification

Raw Materials Used

Natural Limestone Lump

Process Overview

Natural ground calcium carbonate is crushed into calcium carbonate (CaCO₃) powder through mechanical grinding, resulting in different fineness levels.
This type of calcium carbonate is known as ground calcium carbonate, often abbreviated as GCC.
The quality of GCC is determined by the quality of the natural ground calcium carbonate and the fineness achieved through grinding.

Product Features

Fine particle size, with particles mainly in the micrometer to tens of micrometers range.
High whiteness, excellent color.
Good particle flowability, low oil absorption.
Irregular particle structure predominates.

Applications

Used in industrial products like plastics and rubber: Calcium carbonate is used as a filler material in industries like the rubber industry. In the rubber sector, it finds extensive use in products like tires, tapes, hoses, and rubber components. In the plastics industry, it is applied to various plastic products such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS, nylon, etc. Calcium carbonate not only serves as a reinforcing filler on its own but can also be used in combination with other fillers like carbon black, white carbon black, clay, and titanium white powder. This achieves partial reinforcement, filling, color adjustment, and improvement of processing and product performance, while reducing the amount of expensive white fillers.
Used in paint and coating products: Synthetic resin coatings, glazes, oil-based paints, latex paints, primers.
Used in agriculture and livestock industry: Soil improvement, crop protection agents, fertilizers, and feed additives.
Used in consumer goods: environmentally friendly garbage bags, etc.
