| Abstract: | Nanocrystalline cellulose(NCC) can be obtained from degrading of natural cellulose or microcrystalline cellulose(MCC) by the method of acid hydrolysis.It has the backbone of cellulose and has many characteristics of nano-size particles.Rheological characters are of great importance for Nanocrystalline cellulose(NCC) colloid.The effects of concentration,temperature,shear rate,pH value and salt concentration on viscosity of NCC colloid have been studied in this paper.Results show that NCC colloid has the character of shear-thinning,good thickening ability in high temperature,high acidity or alkalinity and the presence of salt.Because of its excellent rheological characters,it is used in many fields including food industry,pharmaceutics industry,daily chemical industry etc. |
