Cosa distingue la polvere di talco, la polvere di quarzo e la polvere di calcio pesante?
Firstly, there is a significant difference in feel between the three. Talc powder has a more delicate and smooth texture. Talc, quartz, and heavy calcium powder are non-metallic minerals. They are crucial for both the industry and commerce. They are primarily used as filler. They can be used in ceramics, glass, paints, coatings, and other industries.
Talco in polvere
Talc powder consists of magnesium oxide, silicon oxide, and hydrogen oxide. Its chemical formula is Mg3[Si4O10](OH)2. It has a specific gravity of 2.7-2.8 and a hardness of 1. It resists corrosion, heat, acid, and alkali. It has strong adsorption, insulation, and a high melting point. It has good chemical stability and durability. It is soft, shiny, and white with snow. It has a delicate texture. Its chemical and physical properties are safe and stable. The crystal structure of talc powder is layered like a crystal. Rubber is easily split into small pieces and has special lubricants. They produce high-quality iron oxide. However, it will diminish their insulation properties.
Polvere di quarzo
La polvere di quarzo è composta principalmente da silice. Ha una densità di 2,65, è insolubile in acqua e resiste ad acidi e alcali. È leggermente solubile in KOH. È altamente resistente al fuoco. Fonde a 1650 gradi Celsius, ha una durezza di 7 ed è pura. La polvere di quarzo bianco è macinata e purificata dal minerale di quarzo. Il suo cristallo è duro e resistente all'usura. È un minerale non metallico con forti proprietà chimiche e termiche anisotropiche. Può essere utilizzato in materiali ignifughi, metallurgia industriale e altri campi.
Polvere di calcio pesante
Heavy calcium powder is mostly calcium carbonate. It is primarily used as a filler. It has good whiteness, purity, and strong chemical properties. Industrial paper production primarily relies on this raw material. It is also used in the paint, coating, and other industries.
