Introduction to ultrafine heavy calcium carbonate from a heavy calcium powder manufacturer

Ultrafine heavy calcium carbonate powder manufacturer introduction: Ultrafine heavy calcium carbonate is a white powder insoluble in water but soluble in acid. It is made from high-quality calcite through ultrafine pulverization and grading to obtain a series of calcite powders with different fineness, referred to as ultrafine heavy calcium powder. It is widely used as a filler in coatings, plastics, rubber, papermaking, toothpaste, medicine, and daily chemical products.

  Heavy calcium powder manufacturers introduce ultrafine heavy calcium carbonate as a white powder, insoluble in water, but soluble in acid. High-quality calcite is ultra-finely pulverized and graded to obtain a series of calcite powders with different fineness, referred to as ultrafine heavy calcium powder. It is widely used as a filler in products such as coatings, plastics, rubber, papermaking, toothpaste, medicine, and daily chemicals.

 Heavy calcium powder

  Heavy calcium carbonate, referred to as heavy calcium, is made by grinding natural carbonate minerals such as calcite, marble, and limestone. Different particle sizes of ordinary heavy calcium powder, ultrafine heavy calcium carbonate, wet-milled ultrafine calcium carbonate, and ultrafine surface-modified heavy calcium carbonate can be provided as needed. Heavy calcium carbonate is widely used in artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, building materials, food, medicine, textiles, feed, toothpaste, and other daily chemical industries as a filler to increase product volume and reduce production costs.

Why is edible calcium carbonate added to toothpaste?

One of the core functions of toothpaste is to clean plaque and stains through abrasives, and edible calcium carbonate, due to its unique physical and chemical properties, has become a widely used choice in the industry. This additive not only needs to meet cleaning needs but also needs to comply with food safety standards. The logic behind it involves multiple considerations of material science, production processes, and consumer safety. Safety: From "edible" to "oral friendly" The "food-grade" attribute of edible calcium carbonate is a prerequisite for its use in toothpaste. According to national standards (such as GB 25584-2010), if toothpaste raw materials claim to be "edible", they must pass strict tests for heavy metals, microorganisms, etc., to ensure safety in case of accidental ingestion. Calcium carbonate itself is chemically stable and can be decomposed into carbon dioxide and calcium ions by gastric acid in the gastrointestinal tract, further reducing the risk. In contrast, industrial-grade calcium carbonate may contain trace amounts of heavy metals or impurities. Although the cleaning effect is similar, there are health risks associated with long-term use. Therefore, the choice of edible calcium carbonate in toothpaste is essentially a double protection against accidental ingestion by consumers. Functionality: Balancing cleaning power and mildness As an abrasive, the hardness and particle size distribution of calcium carbonate directly affect the cleaning effect. Its Mohs hardness is about 3, lower than that of tooth enamel (about 5), which can effectively remove


How to choose the right food-grade calcium carbonate product?

How to choose the right edible calcium carbonate product? In today's era of increasing health awareness, many people are paying attention to calcium supplementation. Whether it is to maintain bone health or to enhance immunity, edible calcium carbonate has become the choice of many people. However, faced with a wide variety of edible calcium carbonate products on the market, how should one choose the right one? Today, let's talk about this topic. Understanding the basics of edible calcium carbonate First, we need to have a basic understanding of edible calcium carbonate. Edible calcium carbonate is a common calcium supplement, which is refined from limestone through chemical reactions. It can not only effectively supplement the calcium elements needed by the human body, but also promote the healthy development of bones. Sounds good, doesn't it? However, choosing the right product is not a simple matter. Product source and production method When choosing edible calcium carbonate, the first thing to consider is the source and production method of the product. Some products may come from unknown sources, or substandard materials may have been used in the production process. Therefore, it is recommended to choose brands that have undergone rigorous testing and have a good reputation. For example, does the product packaging have relevant certification marks, and does it meet national food safety standards? These can help you


Unveiling the Multiple Roles of Calcium Carbonate: From Nature to Food

From nature to food: Unveiling the multiple roles of calcium carbonate Have you ever considered that calcium carbonate is more than just a mineral? In our lives, its roles are astonishingly diverse! From our daily diet to pharmaceutical formulations, it's everywhere. Today, let's talk about this seemingly simple yet extremely important compound - food-grade calcium carbonate. What is calcium carbonate? Calcium carbonate (CaCO3) is a natural mineral commonly found in limestone, marble, and seashells. Its chemical structure allows it to have wide-ranging applications in many fields. You might be thinking, "What does this have to do with my life?" Actually, it has a lot to do with it! For example, food-grade calcium carbonate is one of the important sources of calcium we ingest every day. Sources of food-grade calcium carbonate There are two main sources of food-grade calcium carbonate: natural sources and synthetic sources. Natural calcium carbonate usually comes from minerals, while synthetic calcium carbonate is manufactured in laboratories. Did you know that many calcium supplements and some food additives include food-grade calcium carbonate to increase calcium content and help us maintain better health? Health benefits of food-grade calcium carbonate The biggest selling point of calcium carbonate is its high calcium content; almost every 100 grams provides about 40 grams of elemental calcium. This is suitable for people of all ages.
