| 中文摘要: |
| 目的 采用高效液相色谱法分析金属罐外壁涂膜中苯和甲苯向内涂膜的迁移规律与影响因素。方法 将食品罐印铁在不同堆码温度、 湿度和压强条件下堆码储放2个月后， 采用体积分数为10%的乙醇模拟液萃取试样内壁涂膜中的苯和甲苯， 并利用正交试验优化得到迁移率最小的贮藏条件。结果未经堆码的金属印铁内涂中未检测到苯和甲苯， 而堆码后的试样内涂中均检出了一定量的苯和甲苯。结论 堆码温度对迁移实验结果的影响比较显著。 |
| 英文摘要: |
| The paper analyzed the migration rule and the influencing factors of benzene and toluene from external coatings to internal coatings by high performance liquid chromatography (HPLC) method. The cans were stored at different stacking temperatures, stacking pressures and stacking humidity for two months. 10% ethanol simulated liquid was used to extract benzene and toluene in the internal coatings, and the orthogonal experiment was used to get the storing condition for the minimum migration. The results showed that benzene and toluene were not detected in the internal coatings without stacking, while a certain amount of benzene and toluene was detected in the stacking samples. The influence of stacking temperature on the experiment results was significant. |
