摘要
研究了四种不同生产路线产出的同类线型低密度聚乙烯薄膜料的拉伸性能、熔融结晶性能、热稳定性能、基本物理性能以及吹制薄膜的透明性能,并在地膜和透明包装膜领域进行了加工试生产。结果表明,以煤基石脑油裂解产出乙烯为原料生产的宁煤DFDA-7042与其他三种不同生产路线产出的同类对比产品综合性能相当,在加工应用领域可以替代同类对比产品。
The tensile properties, melting and crystallization properties, thermal stabilities,transparency of blown molded films and other basic physical properties of four linear low density polyethylene( LLDPE) for films produced by different processing technologies were investigated. And the processing and application experiments of these samples were performed in agriculture films and transparency packaging films.The results indicate that the comprehensive properties of the LLDPE DFDA-7042 which is produced by the method of coal based naphtha cracking could be the same with the products produced from other methods. It could be used to replace the other contrast products in the area of processing and application.
