| Abstract: | A brief introduction of how calcium carbide residue comes into being and its harm.Using calcium carbide residue as raw material,first transform it into dihrdrate gypsum through acidification,then synthesize gypsum whiskers by hydrothermal method.Investigate the influences of the concentration and dosage of sulfate on the quality of product gypsum,and the influences of slurry pH on the length and length diameter ratio of the steam-cured product gypsum whiskers.Introduce the application of gypsum whiskers in the industries of friction material,plastic,filling materials and so on. |
