Gypsum powder fineness and water absorption rate of the plaster mold life has an important impact. Gypsum powder too thick, mold used for a period of time, due to corrosion plaster mold image, the surface will appear coarse, uneven surface of the mold plaster mold making videos, so the rough surface of the body, affect the finished appearance Buying plaster mold, reduce die life; however, too small particles (specific surface area> 1500cm2 / g), since the crystals have a greater stress, strength decreases, also resulting in decreased die life Hulunbeir plaster mold, at the same time, fine through fine gypsum mold poor water absorption. Proved: gypsum powder particle control about 80 percent of maintaining the same particle size and fineness of 120 mesh sieve is less than 1%, not only to the inner surface of the mold has a good feel, and a higher strength and better water absorption rate. A gypsum plaster, a natural mineral found on Earth. During 1770, it is the first time in Paris, France Montmartre districts (Montmartre Section) after the excavated materials for industrial use, it is named [plaster].
