我国己内酰胺产业现状及战略发展

Status and strategic development of China caprolactam industry

分析了新常态下我国己内酰胺(CPL)产业的发展现状、面临的形势与挑战,并对我国CPL的战略发展提出建议。2015年我国CPL生产能力达2 350 kt/a,产量为1 783 kt,自给率为87.6%,预计到2020年我国CPL生产能力将达到3 450 kt/a;CPL主要用于聚酰胺6(PA 6)纤维、工程塑料和薄膜,2015年我国PA 6切片消费量为2 461 kt,其中,用于PA 6纤维的消费量为1 970 kt,占比约80%,用于PA 6工程塑料和薄膜的消费量为491 kt,占比约20%;新常态下,我国CPL产业面临着纺织品增速下滑、CPL产能过剩、替代品竞争激烈、资源环境约束增强的挑战,我国CPL产业发展应控制新建生产能力的合理增长、发展先进生产工艺、拓展下游产品的应用领域、注重环保清洁生产。

The development status and the facing situation and challenge of China caprolactam （ CPL） industry were analyzed in new normal economy .The suggestion on the strategic development of China CPL industry was put forward .The production ca-pacity of CPL reached 2 350 kt/a, the output 1 783 kt and the self-support rate 87.6%in 2015 in China.The production ca-pacity of CPL was predicted to be 3 450 kt/a in 2020 in China.CPL was mainly used for polyamide 6 （ PA 6） fibers, engineering plastics and membranes .The consumption of PA 6 chip was 2 461 kt in 2015 in China , 1 970 kt for PA 6 fibers accounting for about 80%and 491 kt for PA 6 engineering plastics and membranes accounting for 20% or so.China CPL industry faced the challenges of the increasing decline of textiles , the excess capacity of CPL , the fierce alternatives competition and the enhanced resources and environment restrain in the new normal economy .The development of China CPL industry should restrain the new capacity , develop the advanced production technologies , expand the application of down -stream products and pay more attention to the environmental requirements .
