Ултрафийнен тағы кальциум картонат 2500 қыш - тасу мен көттеу үшін жоғарғы кальциум картонат

Product Characteristics

High Purity and Whiteness: The calcium carbonate content is generally not less than 98.5%, with extremely low impurity content. It has high whiteness, usually reaching over 96%, which is beneficial for improving the hiding power, color purity, and decorative effect of coatings.

Ultrafine Particle Size: With a fineness of 2500 mesh, its particle size is very fine, and the D50 particle size is about 2 μm. Such fine particles can provide a large specific surface area, which is beneficial for improving the dispersion of calcium carbonate in coatings and enhancing its combination with resin materials.

Good Activity: After surface activation treatment, the surface of the particles is covered with active substances, which significantly improve its lipophilicity and dispersibility in organic media such as coatings. It can be evenly dispersed in the coating matrix, improving its compatibility with resins and other substances.

Proper Oil Absorption Value: The oil absorption value is generally within the range of 30 - 35 g/100 g. This oil absorption value allows it to absorb an appropriate amount of resin and additives in coatings, which helps to adjust the viscosity, fluidity, and drying properties of coatings.

Good Chemical Stability: It has excellent chemical stability, is not easily affected by general chemical substances, and can maintain stable performance in different chemical environments, which is beneficial for the long - term storage and use of coatings.

Functions in Paint and Coatings

Improving Coating Properties: It can increase the solid content of coatings, thereby increasing the thickness of the coating film. Its high hardness can significantly improve the wear - resistance of coatings, prolonging the service life of the coating.

In addition, it can improve the hiding power, whiteness, gloss, and dispersion stability of coatings, enhance the weather - resistance of the coating film, enable it to maintain good performance under various harsh climatic conditions, and reduce the risk of hygroscopic deformation of the coating.

Adjusting Coating Processing Performance: The 2500 - mesh ultrafine heavy active calcium carbonate has regular particle shapes and is easy to disperse in coatings, which can improve the leveling and construction performance of coatings, making them easier to brush, spray, or roll during construction, and improving work efficiency.

Product Advantages

Wide Range of Applications: It is suitable for various types of coatings, such as architectural coatings, industrial coatings, and decorative coatings, and can meet the performance requirements of different products in different fields.

Stable Quality: With strict quality control, the physical and chemical properties of Ultrafine Heavy Active Calcium Carbonate 2500 Mesh are relatively stable.

This ensures the consistency of product performance during production, reduces product quality fluctuations caused by raw material differences, and is conducive to the large - scale production and quality control of coating manufacturers.

Cost - Effective: While ensuring product performance, it has a relatively reasonable price. Compared with some high - performance fillers, it has a certain price advantage, which can help manufacturers reduce production costs and improve the market competitiveness of coating products.
