Guibao Brand Calcium Carbonate 2000 Mesh - Superfine Calcium Carbonate for Plastics and Coatings

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

Ultra - fine Particle Size: The 2000 - mesh calcium carbonate has extremely fine particles, with a D50 particle size of about 5 - 7 μm. Such fine particles can be uniformly dispersed in plastics and coatings, filling the microscopic gaps in the materials and improving the smoothness and surface quality of the products.

High Purity: Usually, the calcium carbonate content is as high as 99% or more, with extremely low impurity content. This ensures that it has minimal impact on the performance of plastics and coatings, helping to maintain the stability of product quality.

Good Whiteness: It has a high whiteness, generally not less than 95%. The high - whiteness calcium carbonate can enhance the whiteness and hiding power of plastics and coatings, improve their decorative and covering effects, and is especially suitable for applications where high - whiteness requirements are needed, such as in the production of white plastics and light - colored coatings.

Low Oil Absorption Value: It has a relatively low oil absorption value, which helps to reduce the amount of additives such as plasticizers and resins in the production of plastics and coatings. This can not only reduce production costs but also improve some properties of the products, such as reducing the viscosity of coating materials and improving their construction performance.

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 use of plastic and coating products in various application scenarios and is not prone to chemical reactions that affect their performance.

Functions in Plastics and Coatings

In Plastics

Reducing Costs: As a filler, it can replace some expensive polymer resins, thereby reducing production costs. Under the premise of meeting the basic performance requirements of plastics, the appropriate addition of Guibao Brand Calcium Carbonate 2000 Mesh can effectively control production costs and improve the economic benefits of plastic products.

Improving Mechanical Properties: It can improve the hardness, rigidity, and dimensional stability of plastics. Appropriate addition can increase the mechanical strength of plastics, making them more resistant to deformation and wear, and prolonging the service life of plastic products. For example, in the production of plastic pipes, the addition of calcium carbonate can improve the pressure resistance and impact resistance of the pipes.

Enhancing Processing Performance: The fine - particle - sized calcium carbonate can improve the fluidity of polymer melts, making the processing and molding of plastics easier and improving production efficiency. At the same time, it can also reduce the shrinkage and warping of plastic products during cooling and solidification, improving the dimensional accuracy of products.

In Coatings
Improving Coating Performance: As a filler, it can improve the thickness, hardness, and wear resistance of the coating film, enhance the adhesion of the coating to the substrate, and improve the physical and chemical properties of the coating.

It can also improve the whiteness and hiding power of coatings, reduce the use of expensive pigments, and reduce production costs.

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

Product Advantages

Wide Range of Applications: It is suitable for various types of plastics and coatings, including polyethylene, polypropylene, polyvinyl chloride, polyester - based coatings, and acrylic - based coatings. It can meet the performance requirements of different plastic and coating products in different fields, such as in the production of plastic products, coatings for architectural decoration, and industrial coatings.

Stable Quality: With strict quality control, the physical and chemical properties of Guibao Brand Calcium Carbonate 2000 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 plastic and coating products.
