高耐磨PA66 70G33L美国杜邦/33%玻纤增强

PA66树脂通常叫做PA66干切片。干燥后的PA66 树脂在包装时的物料温度通常较高, 一般可达80 ℃以上。为防止PA66干切片在包装后储存时含水率升高, PA66干切片的包装都是采用气密性良好的内置铝箔的复合包装袋包装和储存。由于包装的物料温度在短时间内很难下降, 加之包装袋内含有一定的氧气, 很容易导致物料在包装袋内储存一段时间后产生表面发黄现象, 从而造成产品质量下降。因此, 了解PA66干切片在包装后储存时表面发黄的原因, 针对性地改进干燥后PA66树脂的输送工艺流程、改变物料在料仓中的存放时间、降低包装袋内的氧含量及改进PA66树脂在包装后的存放习惯, 对于稳定和控制产品质量十分必要。

PA66尼龙树脂密封处理:

要避免干燥后的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, 可以采取如下方法: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;在包装时采用抽真空的方法降低PA66树脂包装袋内的氧含量。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36h, 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15cm左右的存放距离, 以利于通风和散热。

Huayun plastic raw material company PA66 automotive applications: PA66 instead of metal targeted applications, in 2011 the world consumed 172,000 tons on the vehicle fuel tank. BASF BASF ultramate PA66 offers a number of superior products to the automotive industry and continues to promote the use of sustainable materials as a key part of the automotive industry. 

The challenge facing the conference today is only the beginning of what is needed to help us move towards a more energy-efficient future as the world&＃39;s car-owning population continues to grow. One of the best ways to reduce fossil fuel dependency is to improve vehicle energy efficiency by using lightweight, high performance molded automotive plastics instead of heavier metal parts. In short: Plastic helps make cars lighter. For every 10% reduction in weight, fuel economy improves by 5-7% saving money at the gas station, and hence less carbon dioxide emissions. The dupont high performance polymer team turned its strength and collective solution to possible problems by working with nylon, in particular Zytel American dupont PA66, the product of DuPont, which had proven its value during the 1973-1974 US oil shortage, when it is used to reduce the weight of the vehicle in the engine, thus increasing the gas mileage.
