Introduction to the Industrial Applications of Ultrafine Calcium Carbonate Powder
What are the industrial applications of ultrafine calcium carbonate powder? Let’s take a brief look at this together below.
In the paper-making industry, as sizing technology has shifted from acid to neutral sizing, calcium carbonate has emerged as a substantial potential market. As a high-brightness paper filler, calcium carbonate can significantly enhance paper performance; its ability to replace more expensive kaolin not only reduces costs but also delivers clear economic and social benefits to paper mills. Ultrafine calcium carbonate particles are small and uniformly distributed, resulting in minimal wear on paper machines. The incorporation of ultrafine calcium carbonate not only lowers production costs but also improves paper strength, brightness, opacity, and smoothness, while imparting excellent elasticity and softness, as well as superior ink absorption and water absorbency. In cigarette paper, magazine paper, dictionary paper, newsprint, and book paper, calcium carbonate is typically added at levels ranging from 5% to over 30%. In specialty papers such as coated base papers and matte coated art papers, the proportion of ultrafine calcium carbonate filler can even exceed 80%.
The printing ink market demands high-performance ultrafine calcium carbonate powder. When used in ink formulations, ultrafine calcium carbonate exhibits excellent dispersibility, transparency, superior gloss and opacity, as well as outstanding ink absorbency and drying properties. Currently, ultrafine calcium carbonate is the predominant filler employed in domestic ink products.
As long as the levels of harmful elements such as lead and arsenic in ultrafine calcium carbonate are kept within safe limits, this material can be used as a calcium-source additive in health foods and the feed industry. It boasts superior quality, cost-effectiveness, and high bioavailability, and has already been the subject of application research in areas such as powdered milk, indicating substantial potential.
Ultrafine calcium carbonate powder can be used as a filler in daily chemical products such as cosmetics, soaps, facial cleansers, and children’s toothpastes. In the pharmaceutical industry, ultrafine calcium carbonate powder is an important component of neutralizing calcium-source additives. As a buffering agent in microbial fermentation, it is employed in the production of antibiotics and exerts certain pharmacological effects in analgesics and gastrointestinal medications.
What are the applications of ultrafine calcium carbonate powder? Let’s take a brief look at this together below.
Ultrafine calcium carbonate powder is a critically important raw material in chemical manufacturing. It is used across a wide range of industries. Chemically, it is non-toxic; the material itself is alkaline, insoluble in water, and exhibits moderate hygroscopic properties.
1. In the manufacturing of rubber products, the addition of a certain amount of ultrafine calcium carbonate powder can reduce raw material consumption, enhance the functional properties of plastic products in China, and improve the light-scattering characteristics of plastic articles.
2. Enhance the gloss of coatings during application, improve product durability, optimize the flow properties of powder coatings, and reduce application costs.
3. When used in cosmetics, ultrafine calcium carbonate powder can effectively remove residual deposits from the teeth without damaging the enamel, thereby helping to maintain oral health.
