Thermoanalysis for Dried Soldago decurrens Lour Powder
Abstract:ObjectiveTo understand the influence of heating dried Soldago decurrens Lour power .MethodsThe thermal properties of dried Soldago Decurrens Lour power was studied by DSC method and TG-DTG method in the static air.ResultsHeated up to 118℃,a mass loss of 6.8% was observed.From 118~387℃,a mass loss of 50.57% was observed.From 388~682℃,a mass loss of 11.79% was observed.Up to 972℃,the mass of remains was only 14%.The maxal peaks at 277℃ and 859℃ in DTG were observed by exothemic decomposed reaction,respectively.ConclusionDuring the storage period of the dried Soldago decurrens Lour powaer,the ambient temperature must be below 8℃.Among the making processes for it,the optimum temperature is below 210℃.
