【摘要】 本文采用微波加热法制备Ag₂WO₄抗菌粉体,试验表明,利用微波法制备Ag₂WO₄抗菌粉体,制备时间缩短、粒径减小、抗菌效果提高。XRD分析表明,Ag₂WO₄粉体具有良好的高温稳定性。将所制得的Ag₂WO₄与氧化锌及二氧化钛按重量比1:1:0.5的比例复合,制得Ag₂WO₄复合抗菌剂,并直接添加到卫生瓷釉中,添加量为3%～5%。经检测,所制得卫生瓷样品的吸水率为1%,外观无明显缺陷、色差及失真,抗菌率达98%以上。更多还原

【Abstract】 In this paper,Ag₂WO₄ antibacterial powder was prepared using microwave heating method.The resuhs showed that Ag₂WO₄ antibacterial powder prepared in this way had smaller size,excellent antibacterial effect and less preparing time,and also had high temperature stability.Composite antibacterial agent was synthesized through mixing Ag₂WO₄ with ZnO and TiO₂ in proportion as 1:1:0.5.The sanitary ware sample whose glaze was added 3%～5%composite antibacterial agent had no obvious glaze disfigurement or color shading,and the antimicrobial rate reach to 98%.更多还原
