LLDPE DFDA-7047L耐候地膜专用料的加工工艺及物理性能

Processing Technology and Physical Performance of LLDPE DFDA-7047L Weather-resistant Mulch Film Special Resin

主要考察了大庆石化总厂新产品LLDPE耐候专用料DFDA-7047L在不同吹胀比、螺杆转速、加工温度下的加工性能及加工条件对薄膜拉伸,撕裂、透光性等物理性能的影响,同时对专用料的基础树脂及目前地膜生产中常用的18D树脂的某些性能进行了考察,进而提出了适宜于新产品的加工工艺。

LLDPE DFDA-7047L weather-resistant special resin was newly developed by Daqing Petrochemical Complex. We checked the performances of the film made from the resin that was influenced by different blow rate, rotational speed of screw, and processing temperature, such as film tesile strength, tear strength, transparency and so on. Moreover, we also checked some performances of DFDA-7047L resin and 18D resin, so as to improve processing conditions to suit new products better.
