Top Ten Application Fields of Nano Calcium Carbonate
Nano calcium carbonate refers to functional inorganic fillers with particle sizes ranging from 1-100nm. Nano calcium carbonate has a 50 year history of application abroad, widely used in industries such as plastics, rubber, papermaking, chemical building materials, inks, coatings, sealants, and adhesives.
Main application scope: PVC profiles, pipes; Wire and cable outer shell adhesive particles; Production of PVC film (rolled film), manufacturing of footwear industry (such as PVC shoe soles and decorative patches), etc. Suitable for engineering plastic modification, PP, PE, PA, PC, etc.
Application characteristics: Due to the lipophilic and hydrophobic surface of active nano calcium carbonate, it has good compatibility with resins and can effectively improve or adjust the rigidity, toughness, smoothness, and bending strength of products; Improving processing performance, enhancing the sulfur transformation performance, dimensional stability, and heat resistance of products has the functions of filling, strengthening, and toughening. It can replace some expensive fillers and additives, reduce the amount of resin used, thereby reducing product production costs and improving market competitiveness.
Nano calcium carbonate has a good reinforcing and toughening effect on PVC plastics, and its main nano properties make the processed PVC plastics have good mechanical properties such as strength, barrier properties, flame retardancy, and thermal stability.
Nano calcium carbonate has a three-dimensional structure and good dispersibility in rubber, and has a good semi reinforcing effect.
Application scope: Natural rubber, nitrile, butadiene styrene, mixed rubber, etc., suitable for rubber products such as tires, hoses, tapes, oil seals, automotive parts, etc.
Application characteristics: After surface modification treatment, nano calcium has good compatibility with rubber, with the functions of reinforcement, filling, color matching, improving processing technology and product performance. It can make rubber easy to mix and disperse, and the rubber gel is soft and the rubber surface is smooth after mixing; It can greatly improve the elongation, tensile strength, tear strength, and other properties of the product; It can reduce the gel content or partially replace expensive white fillers such as titanium dioxide and white carbon black, and improve the market competitiveness of the product.
Application scope: Silicone, polyurethane, epoxy and other sealing structural adhesives.
Application characteristics: Used in sealing adhesive materials, it has good affinity with the adhesive material, can accelerate the cross-linking reaction of the adhesive, greatly improve the thixotropy of the system, enhance dimensional stability, improve the mechanical properties of the adhesive, and has a large amount of addition, achieving dual effects of filling and reinforcement. At the same time, it can make the surface of the rubber material shiny and delicate.
Nano calcium carbonate can be used as a pigment filler, with advantages such as delicacy, uniformity, high whiteness, and good optical properties. It has a steric hindrance effect and can suspend Lide powder with high formula density in paint making, playing a role in preventing sedimentation. After painting, the whiteness of the paint film increases, the gloss is high, and the covering power does not decrease, which makes it widely promoted and applied in the paint industry.
Application scope: water-based coatings and oil-based coatings.
Application characteristics: greatly improve the thixotropy of the system, significantly enhance the adhesion, scrub resistance, stain resistance, strength and surface smoothness of the coating, and have good anti settling effect. Partially replacing titanium dioxide to reduce costs.
Application scope: Suitable for offset printing ink, gravure printing ink, etc.
Application characteristics: Ink formulated with nano calcium carbonate has good body bone and viscosity, thus possessing excellent printing performance; Good stability; Dry quickly and without any adverse effects; Due to the small particles, the printed material is smooth and the dots are complete, which can improve the smoothness of the ink and is suitable for high-speed printing.
The paper industry is the most promising market for the development of nano calcium carbonate.
Application scope: cigarette paper, record paper, booklet printing paper, high whiteness copperplate paper, as well as high-end sanitary napkins, diapers, etc.
Application characteristics: Adding nano calcium carbonate to papermaking can improve the paper's bulk density, apparent fineness, and water absorption; Improve the strength and high-speed printability of specialty paper; Adjust the burning speed of cigarette paper.
Feed
Nano calcium carbonate can be used in the feed industry as a calcium supplement to increase the calcium content of feed.
Cosmetics
The use of nano calcium carbonate in cosmetics can partially replace titanium dioxide due to its high purity, good whiteness, and small particle size.
Food
Suitable for food additives made from precipitation, light calcium carbonate, and food additives made from crushed limestone, calcite, and oyster shells, heavy calcium carbonate can be used as nutritional fortifiers, loosening agents, stabilizers, processing aids, etc.
Other
It can be used as a carrier material in medicine, fertilizers, pesticides, and can also be used in the production of refractory insulation materials, calcium citrate, and other materials.
Summary
In the next few years, the demand for nano calcium carbonate in developed countries will grow at an average annual rate of 10%, and in China it will grow at an average annual rate of 20%.
