摘要
目的研究网购折叠硅胶水壶产品质量的相关参数。方法参照相应的国标方法检测网购折叠硅胶水壶产品倾倒试验和手把及壶体的连接强度、硬度、挥发性物质、高锰酸钾消耗量、总迁移量、重金属(以Pb计)。结果倾倒试验结果和手把及壶体的连接强度结果均满足标准要求,热水老化和热空气老化处理后大部分样品硬度变大;高锰酸钾消耗量、总迁移量和重金属测试结果都很低,远小于国家标准限量值,合格率为100%。挥发性物质含量超出参考值比率高达86.6%,且66.6%在参考值2倍以上。结论热老化会使样品硬度发生变化;所测样品中挥发性物质含量较高,应引起监管部门重视,督促企业提高产品质量。
Objective To study the product quality related parameters of folding silicone kettles purchased online.Methods Referring to the corresponding national standard method,the pouring test,connection strength of handle and body,hardness,volatile substances,potassium permanganate consumption,overall migration limit,heavy metal(calculated by Pb)were detected.Results The results of pouring test and connection strength of handle and body all met the standard requirements.The hardness of most samples increased after hot water aging and hot air aging.The test results of potassium permanganate consumption,overall migration limit and heavy metal were very low,and were far less than the limit value of national standard.The acceptance rate was 100%.The ratio was up to 86.6%of volatile substances content which exceeded the reference value and 66.6%was more than twice of the reference value.Conclusion The hardness of the sample will change with the thermal aging.The high volatile matter content in the measured samples should be paid attention by the regulatory authorities and urged the enterprises to improve the product quality.
