| Abstract: | Goal：Research on the influence of sodium sulfate and other things to gypsum congealment speed. Method：When we modulate the calcium plaster,we can add the coagulation accelerator and compare the time of coagulation. Result：The sodium sulfate and other things have the obvious promoter action to the gypsum congealment. Conclusion：When we use gypsum to pick up three-dimensional trail,we should choose the sodium sulfate with suitable density as the promotion coagulation. |
