粒子体积比法测定乳液热力学稳定性
The Determination of Chemical Stability of Emulsion by Particulate Volume Rate Method
【摘要】 应用线性变温法在不同温度(T)与不同时间对聚丙烯酸酯类乳液凝聚过程中平均粒径进行测定,以粒子体积比V0/Vt,替代浓度比Ct/C0,并运用热力学方程求得凝聚活化能E及反应速度常数K,与实测得的反应速度常数较接近
【Abstract】 The chemical stability of polyacrylate emulsion is determined by linear nonisothermal and particule volume method. The activation energy E and the rate constant K was found. So we can predicate the shelf-life of emulsion.
