The initial setting is more than or equal to 8, the final setting is less than 30, the consistency is 46%, and the compressive strength is 39MPa. It is suitable for rolling forming ceramic molds or casting tools.
Gypsum powder: monoclinic mineral, the main chemical component is calcium sulfate (CaSO4). It can be used in cement retarder, gypsum building products, model making, medical food additive, sulfuric acid production, paper-making filler, paint filler, etc.
The surface of high-strength gypsum powder is tender, smooth, bright and hard, nails are not easy to scratch, and handling friction is not easy to scratch and remove powder, which completely changes the shortcomings of ordinary gypsum products, such as rough appearance, dull appearance, hardness and easy to scratch and remove powder, and is a better material for upgrading gypsum products. Especially quick-drying, the surface is completely dry in 20-30 minutes, it can be demoulded and stacked together, and it can be packaged and delivered from the factory, which can save a lot of gardens, supports, molds and time, greatly improve the compliance and increase the benefits.
Performance parameter 1, water-gypsum ratio: (50-60): 100. Time: initial setting: 3-6 minutes; Final setting: 8- 10 minutes; Initial baking: 10- 15 minutes; Demoulding:15-20min; Clock drying: 20-30 minutes; 3. Strength after drying: 6Mpa compressive strength 65438+. Grade II ≥60% fineness ≥ 120 mesh.
