    摘要: A process is described for the production of fiber-containing plastic-formed plaster of Paris products which have superior hardness, surface smoothness and flexural strength as well as good extrusion characteristics and physical integrity. In the process of this invention a composition comprising specified concentrations of plaster of Paris, natural or synthetic fiber, latex, hydromodifier and water is formed into a plastic tractable mixture which may be extruded, molded, or otherwise plasticformed under pressure and then set to produce the desired shaped product. Additional materials such as auxiliary cementing agents, fillers and the like may also be present.
