摘要
介绍了石膏模具的组成，应用DTA－TG对出石膏粉、石膏模具和化学纯二水石膏进行了热分析。采用微波能对石膏模具进行快速干燥，研究了它的干燥过程及对石膏模具的影响．
Following the description of the composition of plaster mould. thermoanalytical investigations of plaster of paris powder,plaster mould and chemically pure CaSO4·2H2O under the conditions of DTA-TG are discussed. The plaster mould was dried quicklyby applying microwave energy. The drying process and the influnce to plaster mould are investigated.
