微波辐照对硫酸锆水解和锆鞣皮粉热稳定性的影响
Effects of Microwave Irradiation on Hydrolysis of Zirconium Sulfate and Thermal Stability of Zirconium Tanned Powder
摘要
Abstract
In this study,the zirconium sulfate solution and the zirconium tanned powder under microwave irradiation were used as experimental samplesand the water bath ones as controls.The pH value,conductivity,dielectric constant and turbidity of the irradiated solution were measured to show effects of microwaveon the hydrolysis of zirconium sulfate;The thermal stability of zirconium sulfate tanned powder under microwave irradiationwas measured by Microscope Heating Test (MHT) and Differential Scanning Calorimeter (DSC).The results show that the pH of irradiated solution is lower,the conductivity,dielectric constant and turbidity are higher and the hydrolysis rate is increased by 24.4％,showing that the microwave irradiation can promote the hydrolysis and agglomeration of zirconium sulfate.Compared with the controls,the shrinkage temperature of zirconium tanned powder can be increased by 1.3-2.4 ℃ and the heat denaturation temperature by 2.2-3.4 ℃,which indicates that microwave irradiation can promote the crosslinking of zirconium and collagen.The effects of microwave on the hydrolysis andagglomeration of zirconium sulfate solution and the promotion of tanning might be considered as annonthermal effect of microwave irradiation in zirconium tanning.关键词
