Application and Characteristics of Heavy Calcium Carbonate in Coatings
Heavy calcium carbonate in coatings is derived from natural minerals like limestone and marble through mechanical grinding. It acts as a multifunctional filler to enhance coverage, mechanical strength, and weather resistance. Its lamellar structure reinforces film integrity. Low oil absorption and minimal VOC emissions make it ideal for eco-friendly water-based coatings. The material’s whiteness and […]
Heavy Calcium Ultrafine Processing Equipment
There are many types of heavy calcium ultrafine processing equipment. They work with ultrafine classifiers to form ultrafine processing systems. These systems can generally achieve ultrafine production results. Currently, the mainstream demand in the calcium market is 600-1500 mesh heavy calcium products. The added value of heavy calcium products is low (compared to talc, barytes, […]
¿Cuál es la tecnología de preparación del polvo de barita?
Barite powder is derived from the mineral barite, composed of barium sulfate (BaSO₄). It forms in low-temperature hydrothermal veins and sedimentary rocks. The chemical composition includes 65.7% BaO and 34.3% SO₃. Substitutions of Sr, Pb, and Ca can also occur in its structure. Barite powder typically appears as plate-like, granular, fibrous aggregates, and crystal clusters. […]
Tecnología de molienda por chorro de aire: la opción preferida para la preparación de polvos ultrafinos.
Ultrafine powders are typically defined as powders with a particle size of less than 10μm. With the advancement of science and technology, many industries require solid materials in powder form.The powders needed must have small particle sizes, high purity, and no impurities. There are also specific requirements for the powder’s particle size distribution. As a […]
¿De dónde proviene el “silicio” en los electrodos negativos a base de silicio?
In recent years, the rapid development of new energy vehicles has raised higher demands for battery performance. Traditional graphite-based anode materials have low specific capacity and are difficult to meet the demand. Silicon has an extremely high theoretical specific capacity, which can effectively improve battery performance. It has great potential for development as an anode […]
Siete tipos de polvos minerales para la modificación del polipropileno
Polypropylene (PP) is a widely used thermoplastic polymer, known for its easy processing and excellent properties. This makes it essential in industries such as packaging, home appliances, and automotive parts. Despite its widespread use, PP has certain limitations. These include high thermal shrinkage, poor performance in low temperatures, and inadequate impact resistance. These shortcomings have […]
