| 摘 要： | 分别研究了透明质酸与两种甲壳素类新保湿剂在RH81%和RH43%时的吸湿动力学特性,以及在RH43%时的保湿动力学特征.结果表明它们的吸湿和保湿行为均符合二级吸附动力学方程,相关系数均达0.999以上.表明它们的吸湿过程主要受化学作用的控制.

| Abstract: | Kinetic analysis of moisture absorption under RH81% and RH43%,and moisture retention under RH43% for Hyaluronic Acid(HA) and two new types of Chitin moisturizers were studied.The results showed that,the Second-Order Model of adsorption kinetic equation can characterize the adsorption process very well and the relation coefficients are all higher than 0.999.It means the adsorption processes of three moisturizers are controlled by chemistry effect. |
