Guangxi Longhua Application fields and characteristics of nano calcium carbonate. Guangxi Longhua As an excellent filler, nano calcium carbonate has advantages such as whiteness, purity, easy coloring, stable chemical properties, low cost, and controllable particle size and shape. It has been successfully applied in rubber, plastics, coatings, inks, and papermaking. Given the superior performance of nano calcium carbonate, more potential values are also becoming development hotspots.

　　1. Application in the rubber industry

　　 Guangxi Longhua Calcium carbonate was used earliest in the rubber industry and is one of the most widely used fillers. The rubber industry is also one of the main application markets for nano calcium carbonate in Guangdong. It can be used in tires, hoses, belts, and rubber products such as seals and auto parts.

　　 Guangxi Longhua Nano calcium carbonate first has the properties of ordinary calcium carbonate. At the same time, due to its ultra-pure, ultra-fine, and surface-modified characteristics, it has a three-dimensional spatial structure and good dispersibility in rubber, which can improve the tensile properties, reinforcing properties, and anti-aging properties of the material.

　　It can not only be used as a reinforcing filler alone but can also be used in combination with other fillers (white carbon black, carbon black, light or heavy calcium carbonate in Guangdong, titanium dioxide, clay, etc.) for filling, reinforcing, coloring, improving product performance and processing technology, reducing the rubber content, or partially replacing expensive white fillers such as titanium dioxide and white carbon black to reduce production costs. Nano calcium carbonate used in the rubber industry requires small particle size, high surface activity, and good dispersibility.

 

 

　　2. Application in the plastics industry

　　Currently Guangxi Longhua The plastics industry is the most mature industry in the application of nano calcium carbonate technology, and the demand for calcium carbonate in Guangdong is very large. Due to the unique and excellent properties of nano calcium carbonate in Guangdong, it can be used as a regulator, reinforcing agent, and semi-reinforcing agent for plastics.

　　 Guangxi Longhua Nano calcium carbonate has a small particle size and good dispersibility, which can reduce pores and voids in plastics, making the mixing and shrinkage of plastics more uniform. Therefore, it can be filled in polymers such as polystyrene, polyvinyl chloride, aldehyde, and phenolic plastics to improve the dimensional stability, hardness, and rigidity of plastic products.

　　At the same time, because Guangxi Longhua Active nano calcium carbonate has lipophilic and hydrophobic properties, which can significantly improve the toughness, rigidity, bending strength, and gloss of products, improve their heat resistance, dimensional stability, and other processing properties, and can partially replace other expensive fillers and additives, thereby reducing product production costs and improving market competitiveness.

　　3. Application in the coatings industry

　　It can be used as a pigment filler and has advantages such as fineness, uniformity, high whiteness, and good optical properties. In paint making, it can suspend lithopone with a higher density in the formula and play an anti-settling role. After paint making, the whiteness of the paint film increases, the gloss is high, and the hiding power does not decrease. This property makes it widely used in the coatings industry.

　　Recent studies have found that ultrafine calcium carbonate has a reinforcing effect and can be used as a coating for anti-stone chipping of car chassis. Using nano calcium carbonate to fill coatings can also greatly improve its flexibility, hardness, leveling, and gloss. Using its blue shift phenomenon, adding it to the latex can shield the coating, achieving the purpose of anti-ultraviolet aging and anti-heat aging, and increasing the heat insulation of the coating.

　　4. Application in the papermaking industry

　　The papermaking industry is the most promising application area for calcium carbonate in China. Nano calcium carbonate can be used as a raw material for coated paper, especially for high-grade coated paper. Due to its good dispersibility and low viscosity, it can replace part of the clay, effectively improving the whiteness and opacity of the paper, improving the smoothness and softness of the paper, improving the ink absorption performance, and improving the retention rate; nano-grade calcium carbonate in Guangdong is used in high-grade sanitary paper, which can increase the toughness, water absorption, and whiteness of the product, making it safer and more hygienic.

　　5. Application in the ink industry

　　 Guangxi Longhua Nano calcium carbonate, as a filler in resinous inks, in addition to playing the role of a general ink filler, also has advantages such as good stability, high gloss, no effect on the drying performance of printing inks, and strong adaptability compared with traditional ink fillers. It can replace more expensive colloidal calcium to improve the gloss and brightness of the ink. Used in high-grade inks, it can improve the adhesion of the ink, reduce the wear and tear of the ink on the machinery, and is suitable for high-speed printing.

　　 Guangxi Longhua Nano active calcium carbonate

　　Chemical name: Guangdong ultrafine active calcium carbonate

　　Molecular formula: CaCO₃

　　Properties: The particle shapes include spindle, spherical, square, chain, and needle shapes; products treated with fatty acids and resin acids have water-increasing properties.

　　1. Guangxi Longhua Uses of nano active calcium carbonate

　　Suitable for various PVC, PP, PE, etc.

　　 Guangxi Longhua The main characteristics of nano active calcium carbonate are good fineness, moderate pH, uniform particle size, regular cubic crystal form, good dispersibility in plastics, and good compatibility with plastics. By adding it to plastics, it can not only give plastics good extrusion processing performance but also greatly improve the tensile strength and elongation at break of plastics, while also reducing the cost of producing plastics.

　　2. Guangxi Longhua Advantages of nano active calcium carbonate

　　(1) Excellent fluidity

　　In the plasticization process of PVC products, it improves fluidity throughout the process, making the mixture easy to stir and changing the processing properties, such as reducing the shrinkage rate of products, improving surface flatness, and making products more resistant to yellowing.

　　(2) Improve surface gloss performance

　　Because it can be mixed well with PVC, it can provide the product's surface gloss, and the tear strength and density are good in film-type PVC products.

　　(3) Excellent nano characteristics

　　Due to its nano-characteristics, its surface is active and can decompose free-moving negatively charged electrons under sunlight and ultraviolet irradiation, leaving behind positively charged holes. This results in high reactivity, making it easy to react chemically with oxygen or organic matter, providing anti-aging properties.

　　Mature application practices

　　It can be added in large quantities to PVC soft and hard plastic products. It is a mature filler product with extensive customer base.
