Longsheng Group Ultra-Fine Light Calcium Carbonate 1250 Mesh - Ultra-Fine Calcium Carbonate for Paper and Paint

Features: non-toxic, odorless, non-irritating, fine particles, rough surface, large specific surface area, high oil absorption value.

Application fields: widely used in paper, plastic, plastic film, rubber, daily chemical, chemical fiber, adhesive, sealant, building materials, paint, paint, ink, putty, linoleum, sealing wax, putty, medicine, food, food, etc.

Waterborne coating industry

The application in the water-based coating industry is more widely used, which can make the coating non-settlement, easy dispersion, good gloss and other characteristics. The dosage of water-based coating is 20-60%.

Paper industry

Calcium carbonate plays an important role in the paper industry to ensure the strength, whiteness and low cost of paper.

Cable industry

It can play a certain insulating role in the cable industry. It can also be used as a friction agent for toothpaste.

Product Characteristics

Fine Particle Size: With a fineness of 1250 mesh, its average particle size is relatively small, usually around 10 - 15 μm. Such fine particles can be well - dispersed in paper and paint systems, playing a good filling role.

In the paper - making process, it can fill the gaps between paper fibers, making the paper surface smoother; in the paint, it can improve the flatness and smoothness of the paint film.

High Purity: The calcium carbonate content is generally high, usually not less than 95%, and the impurity content is extremely low. High - purity light calcium carbonate has little influence on the color, stability, and other properties of paper and paint. It can ensure that the paper has high whiteness and good printability, and also maintain the color purity and stability of the paint.

Good Whiteness: It has excellent whiteness, generally reaching over 90%. The high - whiteness ultra - fine light calcium carbonate can significantly improve the whiteness of paper, making the paper look more delicate and clean, and at the same time, it can also enhance the hiding power and decorative effect of the paint.

Low Oil Absorption Value: The oil absorption value is relatively low, usually in the range of 20 - 30 g / 100 g. In the paint - making process, a low oil absorption value helps to reduce the amount of resin and other additives, which can not only reduce production costs but also improve the fluidity and drying properties of the paint. In the paper - making process, it is beneficial to improve the sizing effect and ink absorption of paper.

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

Functions in Paper and Paint Industries
In the Paper Industry:
Improving Paper Quality: As a filler, it can improve the smoothness, whiteness, and opacity of paper. The fine - particle - sized ultra - fine light calcium carbonate can fill the gaps between paper fibers, making the paper surface smoother, improving the printing adaptability and gloss of the paper.

At the same time, it can also increase the bulk density of the paper, making the paper feel thicker and more textured.

Reducing Production Costs: The addition of ultra - fine light calcium carbonate can reduce the amount of pulp used, thereby reducing production costs.

Under the premise of meeting the quality requirements of paper, appropriately increasing the amount of calcium carbonate added can effectively control production costs.

In the Paint Industry:

Improving Film - Forming Properties: As a filler and pigment extender, it can increase the thickness, hardness, and wear resistance of the paint film. The ultra - fine - particle - sized calcium carbonate can improve the flatness and smoothness of the paint film, enhance the gloss and decorative effect of the paint film, and at the same time, it can also improve the adhesion of the paint to the substrate.

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

Product Advantages

Wide Range of Applications: It is suitable for various types of paper, such as printing paper, writing paper, coated paper, etc., and is also applicable to various paint systems, including architectural coatings, industrial coatings, and wood coatings.

It can meet the performance requirements of different products in different fields, which is conducive to improving the overall quality of paper and paint.

Stable Quality: With strict quality control, the physical and chemical properties of Longsheng Group Ultra - Fine Light Calcium Carbonate 1250 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 paper and paint products.
