In the vast world of chemical raw materials, there is a seemingly ordinary yet highly powerful material that is quietly transforming the manufacturing processes and product performance of multiple industries. This material is modified calcium carbonate. After surface activation treatment, modified calcium carbonate is no longer just a simple filler but has become a key […]

Active calcium carbonate, through surface activation and modification, has evolved from a basic filler into a multifunctional material. It significantly enhances the performance and efficiency of industries such as rubber, plastics, papermaking, coatings, and building materials, while drastically reducing costs. It has become a secret weapon for the green development of manufacturing industries. In the

Calcium carbonate is the most commonly used inorganic powder fillers. It is inexpensive, abundant, non-toxic, and odorless. It has a whiteness of up to 96%, can be easily colored, and has excellent chemical stability. It is easy to dry and widely used in many plastics. Calcium Carbonate There are three kinds of powder fillers of

Limestone is a key raw material for the production of cement, concrete aggregates, and lime. Its crushing and grinding generally follow a dry process. The process varies based on the specific application. For limestone used in metallurgy and road construction, the material is typically crushed and screened. For limestone used as a feed additive or

Currently, the amount of fillers and pigments used in papermaking ranks second only to fiber as one of the most important raw materials. Common papermaking fillers include calcium carbonate, talc, kaolin, wollastonite, bentonite, and others. As the acidic papermaking process gradually shifts towards neutral and alkaline processes, calcium carbonate, as an important raw material in

The limestone grinding process involves mining, crushing, and processing natural limestone ore into industrial raw materials of various specifications. It is widely applied in construction, building materials, chemicals, and metallurgy. Limestone Characteristics and Applications Chemical composition: Mainly calcium carbonate (CaCO₃), with small amounts of magnesium oxide, silica, and other impurities. Main applications: Limestone Mining Process

Porous calcium carbonate (CaCO₃) microparticles have gained significant attention due to their wide applications in areas such as chromatography analysis, loading of biological macromolecules, pharmaceutical release, biomimetic minerals, and the construction of superhydrophobic surfaces. Preparation Techniques for Porous Calcium Carbonate Template methods have become the mainstream approach for preparing porous calcium carbonate. These methods use

Calcium carbonate (CaCO₃) is one of the most important and widely used non-metallic mineral materials in modern industry, with applications spanning plastics, paper, coatings, rubber, construction, and advanced materials. Its raw mineral sources are diverse, including calcite, limestone, marble, chalk, and aragonite, each exhibiting unique physical and chemical characteristics. To obtain powders with the required

In lime kiln calcination, the choice of limestone raw material is crucial. It directly affects the quality of lime products, production efficiency, and the economic benefits of enterprises. The main selection standards for limestone used in lime kilns are as follows: Chemical Composition Physical Properties Geological and Mining Conditions Overall, selecting limestone for lime kilns

Q: What is Calcium Carbonate Modification? Why is Modification Necessary? A: Calcium carbonate modification refers to altering the surface properties of calcium carbonate particles using physical or chemical methods. This process improves their performance in various applications. Calcium carbonate is widely used in plastics, rubber, coatings, and other industries. However, it faces several issues that
