摘要
采用热重分析法(TGA),热机械分析法(TMA)和差示扫描量热法(DSC),分别对四种调制后的石油系纺丝用沥青和A240沥青作了热性质的研究,考察了五种沥青的相对热稳定性、玻璃化转变温度(Tg)及比热与温度的关系,并对不同沥青进行了分析比较。
Studies on the thermal properties of four petroleum pitches for spinning and A240 pitch after concocting Were made by thermal gravimetric analysis (TGA) , thermomechanical analysis (TMA) and differential scanning calorimetry (DSC) . Relative thermal stability, vitrification transformation temperature (Tg) and relationships between specific heat and temperature of the five pitches were investigated.Analysis and comparison were also made between different pitches.
