摘要
研究了甲壳胺溶液中的醋酸和尿素含量的改变对溶液流变参数的影响.研究表明:各种组成的甲壳胺溶液的n均小于1,是切力变稀型流体.调节溶液配比,可改变溶液的流变性质,改善可纺性,并对不同温度和时间下溶液的降解作了讨论.
The effects of acetic acid and urea content on rheological parameters of chitosan solution are discussed. The value n of different composition solution is less than 1, namely, it is a shear-thinning fluid. Regulating the chitosan solution's composition can result in the change of its rheological behaviour and the improvment of its spinnability. It studied also the degradation of the chitosan solution under varieties of temperature and time.
