As a multifunctional additive, nano calcium carbonate plays a vital role in many industrial fields. With its unique physical and chemical properties, such as high hiding power, high whiteness, excellent dispersibility and paint film performance, and low oil absorption value after modification, nano calcium carbonate is widely used in calendered film, BOPP film, cable material, powder coating, PVC pipe fittings and biodegradable materials, etc., bringing significant improvements and innovations to the material performance in these fields.First of all, in the production process of plastic products such as calendered film and BOPP film, the addition of nano calcium carbonate can effectively improve the mechanical strength and surface gloss of the product. Because nano calcium carbonate particles are extremely fine (usually the particle size reaches 2 microns and more than 95% of the particles are of the same size), they can be evenly distributed in the substrate to form a denser structure. This structure not only enhances the overall hardness and toughness of the material, but also improves the transparency and gloss of the film. In addition, nano calcium carbonate also has a good filling effect, which can reduce production costs without sacrificing material performance, which is undoubtedly a huge attraction for companies pursuing economic benefits.Secondly, for cable materials, the application of nano calcium carbonate cannot be ignored. It can not only increase the insulation performance of cable materials, but also improve weather resistance by reducing moisture absorption. This is because after special treatment, the surface activity of nano calcium carbonate is enhanced, and it can better combine with other components, thereby effectively preventing the influence of the external environment on the inside of the cable. At the same time, the addition of nano calcium carbonate can also adjust the viscosity of the cable material, making it easier to process and shape, and improve production efficiency and product quality.Furthermore, in the powder coating industry, nano calcium carbonate stands out for its excellent dispersibility and paint film performance. When added to powder coatings as a filler, nano calcium carbonate can significantly improve the flatness and smoothness of the coating, and give the coating higher wear resistance and impact resistance. Especially for those equipment or facilities that need to be exposed to harsh environments for a long time, the use of powder coatings containing nano calcium carbonate for protection can greatly extend their service life. In addition, since nano calcium carbonate has an extremely low oil absorption value, this means that the amount of organic solvents can be reduced in formula design, which is both environmentally friendly and economical.In the field of PVC pipe manufacturing, nano calcium carbonate plays an important role. On the one hand, it can increase the rigidity and dimensional stability of PVC pipes; on the other hand, by optimizing the production process parameters, nano calcium carbonate can be optimally dispersed in the PVC matrix, thereby obtaining better comprehensive mechanical properties. In addition, nano calcium carbonate also has a certain toughening effect, which helps to overcome the disadvantage of the greater brittleness of traditional PVC materials.Finally, in the research and development of biodegradable materials, nano calcium carbonate also shows great potential. With the continuous improvement of global awareness of environmental protection, the development of fully degradable environmentally friendly materials has become one of the research hotspots. Nano calcium carbonate is very suitable for the preparation of biodegradable plastics due to its natural source and non-toxic properties. Studies have shown that adding an appropriate amount of nano calcium carbonate to biodegradable polymers can not only accelerate the degradation rate of the material, but also improve the processing performance and final use performance of the material to a certain extent.In summary, nano calcium carbonate has demonstrated irreplaceable value in multiple industrial fields with its excellent performance characteristics. Whether it is to improve product quality, reduce costs or promote sustainable development, nano calcium carbonate provides strong support for related industries. With the advancement of technology and changes in market demand, the application prospects of nano calcium carbonate will be broader in the future.
