City Sludge’s Differential Scanning Calorimetry Analysis

Abstract:

The differential scanning calorimetry is a thermal analysis. Under program controlled temperature, measure and input to the relationship between the the sample and the reference’s power difference and temperature. The curve which the differential scanning calorimetry recorded called DSC curve. DSC curve in the sample’s rate of endothermic or exothermic as ordinate and in temperature or time as abscissa, which can determine a variety of thermodynamic and dynamics parameters, such as specific heat capacity, the reaction heat, thermal changes, phase diagram, reaction rate, rate of crystallization, polymer crystallinity, purity of a sample,etc. The method has a wide temperature range-175 ~ 725 °C, high resolution, less samples . This topic utilizes differential scanning calorimetry and had a pyrolysis experimental analysis for urban sludge. Due to the rapid development of technology and analyzer’s constant improvement, and computer technology’s speedy development, DSC plays an increasing role in the sludge treatment field.
