摘 要：
对金属罐内壁涂层中的有害物质(双酚A-二缩水甘油醚双水合物,以下简称BADGE·2H2O)向食品模拟液在给定条件下的迁移特性进行了数值仿真,并与对应条件下的实验结果进行了对比、分析。结果表明:温度、初始浓度、涂层厚度对物质迁移的影响较大;对于给定的温度,温度越高,则迁移达到平衡时所需要的时间越短,迁移量越大;对于给定的初始浓度和涂层厚度,初始浓度越大,涂层厚度越厚,则迁移量越大;同时,在不同温度下,BADGE·2H2O从食品罐内壁涂层向水性模拟液迁移的数值解与实验值最大差值为0.023μg/mL。数值仿真与实验结果有较好的一致性。

摘 要：
Under the given conditions,the numerical simulation of the hazardous substance(BADGE·2H2O) migrated from inside wall of food cans coatings into food simulation liquid was analyzed,and the experimental results was compared with under the corresponding conditions.The result showed that migration was caused more by temperature,initial concentration and coating thickness.For a given temperature,the higher the temperature,the time when BADGE·2H2O achieved the migration balance was shorter,the amount of migration was larger.For the given initial concentration and coating thickness,with the thicker coating,the higher the initial concentration,the amount of migration was larger.At the same time,the biggest concentration difference between numerical solution and the experimental data which BADGE·2H2O migrated from inside wall of food cans coatings to water simulation liquid at different temperature was around 0.023μg/mL.There was a good fitting relationship between numerical simulation and experimental result.
