Guibao Brand Heavy Calcium Carbonate 5000 Mesh - Ultra-High Purity Calcium Carbonate for Paint and Polymer Industries

Calcium carbonate is a non-toxic, tasteless, non-irritating white powder, one of the most versatile inorganic fillers. It is dry and does not contain crystallized water, and is exposed to the air.

Almost insoluble in water, insoluble in alcohol, dilute acetic acid, dilute hydrochloric acid, dilute nitric acid to boil and dissolve;Heat is decomposed into calcium oxide and carbon dioxide.

Calcium carbonate has not only cheap, abundant resources, high grade, etc, but also has some properties of fllers, widely used in coatings, plastics, printing ink, putty, plastic flm, chemical fiber, sealants, adhesives, daily-used chemical industry, medicine, rubber, paper, toothpaste, cosmetics, food, textile, building materials, fodder, etc.

Product Characteristics

Extra - fine Particle Size: With a fineness of 5000 mesh, its particle size is extremely small, reaching around 0.5 - 1 μm or even smaller. Such fine particles can be uniformly dispersed in paint and polymer systems, filling the microscopic gaps and pores, which is beneficial for improving the smoothness and compactness of the final products.

Ultra - high Purity: The calcium carbonate content is usually as high as 99% or more, with extremely low impurity content. This high purity ensures that it has minimal impact on the color, stability, and other properties of paints and polymers, helping to maintain the high - quality performance of the products.

Excellent Whiteness: It has a high whiteness, generally not less than 96%. The high - whiteness calcium carbonate can enhance the whiteness and hiding power of paints, improve their decorative and covering effects. In the polymer industry, it can also improve the color stability and uniformity of polymer products.

Low Oil Absorption Value: The oil absorption value is relatively low, typically in the range of 8 - 15 g / 100 g. The low oil absorption value helps to reduce the amount of resin and other additives in paints and polymers. This can not only cut production costs but also improve some properties of the products, such as reducing viscosity and improving fluidity.

Good Chemical Stability: It has excellent chemical stability and is not easily affected by chemical substances. It can maintain stable performance in different chemical environments, which is beneficial for the long - term storage and use of paints and polymers and is not prone to chemical reactions that affect their quality.

Functions in Paint and Polymer Industries

In the Paint Industry:

Improving Film - Forming Properties: As a filler, it can increase the thickness, hardness, and wear resistance of the paint film, enhance the adhesion of the paint to the substrate, and improve the physical and chemical properties of the paint. The extra - fine - particle - sized calcium carbonate can also improve the smoothness and gloss of the paint film, making the surface of the coating more delicate and beautiful.

Enhancing Color Performance: It can improve the whiteness and hiding power of paints, reduce the use of expensive pigments, and thus reduce production costs. At the same time, it can also improve the color stability and uniformity of paints, making the colors more vivid and durable.

Improving Dispersion and Stability: The fine particle size of calcium carbonate helps to improve its dispersion in paints, making the paint system more stable and less prone to sedimentation. This is beneficial for maintaining the uniformity and consistency of paints during storage and use and improving the quality of the paint film.

In the Polymer Industry:

Increasing Volume and Reducing Costs: It can be used as a filler to increase the volume of polymer products, thereby reducing the amount of polymer resin used and reducing production costs.

Improving Physical Properties: It can improve the stability, hardness, and stiffness of polymers, as well as their processing performance. It can also enhance the heat resistance, anti - scratch properties, smoothness, and toughness of polymers, improving the overall performance of polymer products.

Improving Dispersion and Compatibility: The ultra - fine particle size and high - purity characteristics of Guibao Brand Heavy Calcium Carbonate 5000 Mesh help to improve its dispersion and compatibility in polymer matrices, reducing the formation of aggregates and improving the homogeneity of the polymer composite.

Product Advantages

Wide Range of Applications: It is suitable for various types of paints, including architectural coatings, industrial coatings, and automotive coatings, as well as for different types of polymers, such as polyethylene, polypropylene, and polyvinyl chloride. It can meet the performance requirements of different products in different fields, which is conducive to improving the overall performance of paints and polymers.

Stable Quality: With strict quality control, the physical and chemical properties of Guibao Brand Heavy Calcium Carbonate 5000 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 manufacturers' large - scale production and quality control.

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 improve the market competitiveness of paint and polymer products.
