| 中文摘要: |
| 以沸石为载体,AgNO3 为反应溶液,通过离子交换方法,将具有抗菌性能的金属银离子固定在多孔性沸石表面,制成了载银沸石抗菌剂,检测了其对大肠杆菌的抑菌效果。实验结果表明,当AgNO3 溶液浓度为0. 1mol/ L,pH 值为6 ~8,反应温度为70 ℃,反应时间为3 h 时,制备的载银沸石抗菌效果最好。然后选择聚乙烯醇(PVA)作为施胶剂,将载银沸石溶于该施胶剂中,采用表面施胶法喷涂到纸张的表面,赋予纸张抗菌性能。经检测,使用聚乙烯醇(PVA)对纸和纸板进行表面施胶以后,纸张的耐破度、耐折度、环压强度、抗拉伸等强度较原纸都有所增强。 |
| 英文摘要: |
| Sliver-loaded zeolite antibacterial agent was prepared by using zeolite was used as carrier and AgNO3 as the exchange solution with ion-exchanging method. The bacteriostatic effect of the antibacterial agent on escherichia coli was detected. The result indicated that the optimum preparing conditions is pH value 6 ~8, AgNO3 concentration 0. 1 mol/ L, the reaction temperature 70 ℃, and reaction time 3 h. Polyvinyl alcohol (PVA) was selected as the sizing agent and the sliver loaded zeolite was added into the sizing agent. Antibacterial paper was prepared by spraying the sizing agent with sliver loaded zeolite on the paper surface. The results showed that the antibacterial has better paper bursting strength, folding resistance, ring crush strength, and tensile strength then the base paper. |
