【Product detail】

Physical and chemical properties: Yuanjiang Brand - alkali magnesium carbonate is a white monoclinic crystal or amorphous powder, ruling, odorless, stable in the air. Relative density 2.16, slightly soluble in water, a weak alkaline aqueous solution, the water solubility of 0.02% (15 degrees). The fusible in acid and ammonium salt solution, in dilute acid decomposition to emit carbon dioxide, heated to 300 degrees above the decomposition, generating water, carbon dioxide, and magnesium oxide.

Purpose: Yuanjiang Brand - alkali magnesium carbonate used as a good filling agent and reinforcing agent of rubber products. Can be used as heat insulation, high temperature resistant fireproof insulation materials. Asbestos excellent insulation, light magnesium carbonate type used in shipbuilding and boiler manufacturing departments and so on, can also be used in the manufacture of advanced glass products, magnesium salt, pigment, paint and daily supplies chemicals, etc. In medicine, used as antacids. Also as a desiccant, stabilizer.color-protecting, carrier, an anti-caking agent.
