干湿环境下丙烯酸树脂粘接剂银离子释放浓度测试

Silver Ion Release Concentration Test of Acrylic Resin Adhesive under Wet and Dry Environment

在干湿环境下,丙烯酸树脂粘接剂存在不同的反应状态,不同反应状态下可释放出不同浓度数值的银离子,为此,测定干湿环境下丙烯酸树脂粘接剂银离子释放浓度。准备实验材料与仪器后,制备丙烯酸树脂粘接剂,借助于外部溶液,设定粘结配比方案,然后连接制备装置并准备丙烯酸树脂粘接剂粘接的干湿环境,消解粘接剂中影响银离子释放的离子,构建银离子释放浓度测定方法。最终的测定结果显示:在干环境下,银离子为残渣和吸附物状态,综合计算分子质量数值结果可知,处于残渣状态的银离子释放浓度为10.4g/L,吸附物状态下的银离子释放浓度为17.4g/L。在湿环境下,银离子处于有机硫化物的结合状态以及碳酸盐的结合态,处于有机硫化物的结合状态下的银离子浓度为8.5mol/L,处于碳酸盐的结合态的银离子浓度为9.4mol/L。

In wet and dry environment,there are different reaction states of acrylic resin adhesive,and different concentrations of silver ions can be released in different reaction states.Therefore,the release concentration of silver ions of acrylic resin adhesive in wet and dry environment was determined.After preparing the experimental materials and instruments,acrylic resin adhesive was prepared.With the help of external solution,the bonding ratio scheme was set.Then the preparation device was connected and the wet and dry environment for acrylic resin adhesive bonding was prepared.The ions affecting the release of silver ions in the adhesive were digested,and the determination method of silver ion release concentration was established.The final determination results show that:in the dry environment,the silver ion is in the state of residue and adsorbate.The comprehensive calculation of molecular weight shows that the release concentration of silver ion in the state of residue is 10.4 g/L,and the release concentration of silver ions in the adsorbate state is 17.4 g/L.In wet environment,silver ion is in the bound state of organic sulfide and carbonate,the concentration of silver ion in the bound state of organic sulfide is 8.5 mol/L,and the concentration of silver ion in the bound state of carbonate is 9.4 mol/L.
