PET切片色相b值的影响因素

Influence factors on the hue b value of PET chip

从PET切片的生产实际出发,从主要原材料、辅助材料、生产工艺等方面分析聚酯切片色相b值的影响因素,提出了控制原材料品质、添加剂的含量、生产工艺,是得到色相b值较好的PET产品的保证。

According to the production practice of PET chip, by analysis of the influnce facters on the hue b value of PET chip were analysed from raw material, auxiliary material, production process. It was pointed out that by con- trolling the raw material quality, additive feeding quantity and production process, the PET chip with better hue can be obtained.
