Was unterscheidet Talkumpulver, Quarzmehl und Calciumcarbonatpulver?
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.
Talkumpuder
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.
Quarzmehl
Quarzpulver besteht hauptsächlich aus Kieselsäure. Es hat eine Dichte von 2,65, ist wasserunlöslich und säure- und alkalibeständig. Es ist leicht löslich in KOH. Es ist sehr feuerbeständig. Es schmilzt bei 1650 Grad Celsius, hat eine Härte von 7 und ist rein. Weißes Quarzpulver wird aus Quarzerz gemahlen und gereinigt. Sein Kristall ist hart und verschleißfest. Es ist ein nichtmetallisches Mineral mit stark anisotropen chemischen und thermischen Eigenschaften. Es kann in feuerfesten Materialien, in der industriellen Metallurgie und in anderen Bereichen eingesetzt werden.
Schweres Kalziumpulver
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.
