文章通过DTA、TG、DSC、静态加热失重及比热的分析研究，全面讨论了苏皖交界地区热液型和沉积型坡缕石的热学性质及有关的热动力学问题。分析表明：被缕石脱水具阶段性，结晶度高的热液型坡缕石其热稳定性优于结晶度低的沉积型的；在50～230℃范围内，热液型坡线石的平均比热为3．069J／g·℃，沉积型的为3．839／g·℃；在常温至400℃范围内，坡缕石脱先吸附水和沸石水的活化能为0．51～0．90kJ·mole(-1)，脱失结合水的活化能为5．44～10．12KJ·mole(-1)；坡缕石脱水和复水反应热焓分析表明，坡缕石吸水所释放出的能量不足以引起水的分解。
In this paper, by means of DTA, TG, DSC, static heating weight loss and specific heat analysis, the thermal properties and related thermodynamic problems of hydrothermal and sedimentary palygorskite in the junction area of Jiangsu and Anhui are comprehensively discussed. The analysis shows that the thermal stability of hydrothermal palygorskite with stage and high degree of crystallinity is better than that with low degree of crystallinity in the dehydration of palygorskite. In the range of 50 ~ 230 ℃, the hydrothermal palygorskite The average specific heat is 3.069J / g · ℃, and the deposition type is 3.839 / g · ℃. The activation energy of desorption water and zeolite water in the range of normal temperature to 400 ℃ is 0.51 ~ The activation energy of debonding water is 5.44 ~ 10.12KJ · mole (-1). The enthalpy analysis of dehydration and rehydration of palygorskite shows that the palygorskite The energy released is not enough to cause water to decompose.
