随着石油化工的发展,聚乙烯生产得到迅速发展,产量约占塑料总产量的1/4。聚乙烯生产的发展趋势显示,生产消费逐步向亚洲地区转移,中国日渐成为最重要的消费市场而令人关注。根据聚乙烯塑料的主要组分与分类,介绍了聚乙烯的性能特点及应用领域,研究了聚乙烯注塑成型加工方法,阐述了低密度聚乙烯的特点与注塑工艺,以及高密度聚乙烯塑料性能与注塑工艺。 With the development of petrochemical industry, polyethylene production has been rapidly developed, the output accounts for about 1/4 of the total output of plastic. The development trend of polyethylene production shows that the gradual shift of production and consumption to the Asian region, China has become the most important consumer market and cause for concern. According to the main components and classification of polyethylene plastic, the properties and application of polyethylene are introduced. The processing methods of polyethylene injection molding are discussed. The characteristics and injection molding process of low density polyethylene and the properties of high density polyethylene plastic And injection molding process.
