What’s the Relationship between Chalk Powder and Magnesium Carbonate?

In the physical exercise, the sportsman often teetering or can’t catch on because of sweatiness. There is a kind of powder which can quickly absorb sweat and increase surface friction. It can prevent the sport accident. When we watching sports programs, especially the gymnastics and weightlifting, the sportsman smear a kind of white powder on their hands. This powder is chalk powder.
      The chemical component of chalk powder is magnesium carbonate. PH value is alkalescence. It is white and nontoxic.

   Why does it can resist skid? It is decided by the physical property of magnesium carbonate. Magnesium carbonate is macromolecular substance, and has large touch surface. Therefore, the static friction force is large. The character of MgCO3 is strong water-absorbing quality. The principle of chalk powder is to absorb sweat in your hands and remain dry.

   The chalk powder is mainly used in these applications: weightlifting, gymnastics, rock climbing, badminton, tennis, basketball, pole dancing and other sports which needs skid resistance. Before exercise, please apply an appropriate amount on your hands, feet or instrument.
