原料助剂对PVC密封垫蒸发残渣性能的影响研究

Effect of Additives on Evaporation Residue of PVC Gasket

研究了PVC密封垫产品中常用原料助剂对蒸发残渣卫生性能指标的影响。结果表明,原料助剂的添加对接触水性和低乙醇食品的PVC密封垫产品的蒸发残渣影响较小;添加的CaCO3填料对乙酸蒸发残渣影响明显,DINCH为增塑剂制备的PVC密封垫乙酸蒸发残渣值最低,ATBC为增塑剂制备的PVC密封垫正己烷蒸发残渣值最低。

Effect of additives on PVC gasket evaporation residue amount was investigated. The results showed that, the use of additives has less effect on PVC gasket evaporation residue when contacting water-based and low-ethanol food; it has obvious impact on acetic acid evaporation residue when using additive CaCO3. PVC gasket has the least acetic acid evaporation residue which using plasticizer DINCH, and the least hexane evaporation residue when using plasticizer ATBC.
