摘要:通过高温分解法制备银氧化锌复合物,并用于羽绒杀菌。研究所制备复合物协同微波对羽绒的杀菌工艺,探讨复合物用量、微波辐射功率、微波辐射时间和微波辐射温度等工艺条件对羽绒抗菌效果的影响,同时对复合物进行循环回收实验。结果表明:所制备银氧化锌复合物协同微波对羽绒的最高抑菌率为53.34%,工艺条件为羽绒与复合物质量比2∶1,微波辐射功率400 W、微波辐射时间2 min、微波辐射温度47 ℃。在最佳工艺条件下对复合物进行连续5次回收,回收后的抑菌率分别为37.24%、18.52%、16.19%、10.69%和8.54%。所制备银氧化锌复合物协同微波对羽绒具有抗菌性,随着回收次数的增加,复合物抗菌效果逐渐减弱。

The composite combined with microwave was applied in downfeather. The influence of the dosage of the composite, microwave power, microwave time and microwave temperature on antibacterial effect of downfeather was discussed. At the same time, recycling experiments of the composite were carried out. All these results show that the highest antibacterial rate of composite combined with microwave to downfeather was 53.34% under the following conditions: the mass ratio of downfeather and the composite 2∶1, microwave power 400 W, microwave time 2 min and microwave temperature 47 ℃. At the same process conditions, the antibacterial rate is respectively 37.24%, 18.52%, 16.19%, 10.69% and 8.54% after recycling five times. The experiment results indicate that the prepared AgZnO composite combined with microwave has antibacterial property to downfeather, and the antibacterial effect gradually diminishes with the increase in the number of recycling.

羽絨体轻松软、弹性好、保温、防寒能力强[1]。中国是生产羽绒、羽绒制品的大国[2]。但羽绒在获取过程中极易携带细菌、病毒,在潮湿环境下易滋生微生物等有害物质,产生异味[3];而羽绒制品多与人体身体直接接触,因此对羽绒杀菌消毒成为衡量羽绒制品质量、保证消费者人身安全的重要环节。目前国内羽绒加工多按下列工艺进行:水洗→洗涤剂与消毒剂或高温高压灭菌[1,4]→清水冲洗→脱水→烘干[5]。在此工艺过程中,羽绒消毒杀菌所采用的消毒剂多为有机类化合物,所产生废水属高浓度有机废水[6],直接排放极易造成环境污染;而高温高压灭菌往往是高能耗、高成本,增加羽绒生产企业经济压力。……
