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.
Keywords:three-dimensional trail  Gesso mini-electric  promotion coagulation  suitable density
