【摘要】 本文主要研究了夹心式超净化材料制备工艺优化以及菌净化性能。首先选择制备夹心式超净化材料的基体原材料,需要综合考虑材料的物理性能,化学性能,生产技术的可行性以及生产成本等因素。解决制备材料过程中出现的问题,设定材料检验标准,确定最佳的制备工艺参数。结果证明,这种新型材料的生产工艺简单。研究夹心式超净化材料的物理性能,结果表明,该材料有良好的力学性能。对这种新型材料过滤霉菌浊液的过滤效率以及滤液的浊度变化值等参数进行测定,结果表明,这种新型材料对水中的霉菌有很高的净化效率,例如,对浊度100NTU左右的菌浊液净化后的滤液浊度最低0.4NTU,过滤效率最高可以达到99.97%,而传统滤布无法过滤掉的水中的霉菌。同时还证明这种材料能够重复利用。对材料的菌净化机理也进行了探讨。在静电纺丝溶液中加入纳米二氧化钛,对夹心式纳米超净化材料改性,研究其抗菌灭菌性能。结果表明,改性的净化材料能够更快、更彻底的杀灭霉菌。

【Abstract】 This article mainly introduces the process to produce a novel sandwich structure super-cleaning material and the property of purification of water containing microzyme with this novel material. Firstly the normal filtration material used to produce the super-cleaning material was chosen by considering the physical and chemical property of the materials, as well as their technological feasibility and cost. The difficulties occurring in the process of production were resolved, the test standard of this novel material were set up and the optimal technological parameters were determined. The results show that the novel sandwich structure ultra-filtration material has simple manufacturing operation. The physical property of this novel material was investigated, and the results show that this novel material exhibits excellence in its mechanical property. Purification of water containing microzyme with this novel material was studied, and parameters such as filtration efficiency, the variety of turbidity value of filtrate were also determined. The results show that this novel material has high filtration efficiency in removing the microzyme in the water, for example, a turbidity of about 100 NTU of water containing microzyme was filtrated, and the results show that the highest filtration efficiency can reach 99.97%, and the lowest turbidity value is 0.4 NTU, however, it is impossible for the traditional filtration material to remove the microzyme in the water. It was proved that this novel material can be reused. The mechanism of purification of water containing microzyme with this novel material was also discussed. The anti-bacterial property of this novel material by adding nano- TiO2 particle to the polymer solution used to electrospin was studied, and the results show that this novel material can sterilize microzyme more quickly and thoroughly.
