| 中文摘要: |
| 将二次通用旋转组合设计法应用于共混膜配方,以壳聚糖 / 二氧化钛抗菌保鲜共混膜的力学性能为目标,选定壳聚糖、增塑剂丙三醇及二氧化钛的添加量为实验因素,建立了数学模型。 通过分析实验结果和优化数学模型,得到了该共混膜最佳制备配方为:壳聚糖添加丙三醇、TiO2 在 100 mL 乙酸溶液中的量分别为 3. 9 g,0. 9 mL,0. 37 g,并预测出此条件下膜的理论拉伸强度为 20. 52 MPa,与实测值 21. 37 MPa 基本相符,验证了该数学模型的可靠性。 |
| 英文摘要: |
| Quadratic general rotary combinational design was applied to optimize the packaging material formulation. The mathematical model was established aimed at the tensile strength of chitosan/ TiO2 antibacterial fresh-keeping blend film based on three factors, namely, the dosages of chitosan, glycerin, and TiO2. The optimal condition was obtained after analysis the mathematical model, where formulation was consisted of chitosan 3. 9 g / 100 mL, glycerin 0. 9 mL/ 100 mL and TiO2 0. 37 g / 100 mL. Under the formulations, the 21. 37 MPa highest tensile strength of the blend film was reached, which was consistent with estimated value of 20. 52 MPa. This result proved that the mathematical model is reliable. |
