德国巴斯夫PA66 树脂在包装后储存时表面发黄现象的产生,可以降低PA66树脂在包装时的温度及包装袋内的氧含量。为了既能保证干燥后的PA66树脂的水分又能降低PA66树脂在包装时的温度,由华韵公司出售可以采取如下方法:1在PA66树脂干燥后的物料输送管线上加装冷冻水夹套,利用热量交换原理来降低干燥后的PA66树脂表面温度;2在包装时采用抽真空的方法降低德国巴斯夫PA66树脂包装袋内的氧含量。另外,为了能更有效地预防干燥后的PA66树脂在包装后储存时表面发黄现象的发生及尽可能地降低在包装时PA66树脂的温度,还要尽量做到:干燥后的PA66树脂在包装前要在成品料仓内暂存36 h,待物料温度充分下降后再进行包装;包装后的PA66树脂垛盘在储存时, 要采取垛盘间距保持在15 cm左右的存放距离,以利于通风和散热。

The occurrence of yellowing onthe surface of BASF PA66 resin during storage after packaging canreduce the temperature of PA66 resin during packaging and theoxygen content in the packaging bag. In order to ensure themoisture content of the dried PA66 resin and reduce the temperatureof the PA66 resin during packaging, Huayun Company can adopt thefollowing methods: 1. Install a chilled water jacket on thematerial delivery pipeline of the dried PA66 resin, and use theprinciple of heat exchange to reduce the surface temperature of thedried PA66 resin; 2. During packaging, vacuum is used to reduce theoxygen content in BASF PA66 resin packaging bags in Germany. Inaddition, in order to more effectively prevent the occurrence ofyellowing on the surface of dried PA66 resin during storage afterpackaging and minimize the temperature of PA66 resin duringpackaging, it is also necessary to try to: the dried PA66 resinshould be temporarily stored in the finished product warehouse for36 hours before packaging, and packaging can only be carried outafter the material temperature has fully decreased; When storingpackaged PA66 resin pallets, a storage distance of about 15 cmshould be maintained between pallets to facilitate ventilation andheat dissipation.
