2015年,我国对苯二甲酸产量为3 088万t,同比增长了16.3%。表观消费量为3 100.9万t,同比增加13.7%。近年我国对苯二甲酸消费情况详见表1。我国对苯二甲酸绝大部分都用来生产各种聚酯产品。从下游消费结构看出:70%的对苯二甲酸用于生产聚酯纤维(其中80%为涤纶);15%用于生产瓶级聚酯;5%用于膜级聚酯,剩余10%用于生产工程塑料及粉末涂料等产品。
In 2015, the output of terephthalic acid in China was 30.88 million tons, an increase of 16.3% over the same period of last year. Apparent consumption of 31.90 million tons, an increase of 13.7%. In recent years, the consumption of terephthalic acid in China is shown in Table 1. Most of China’s terephthalic acid are used to produce all kinds of polyester products. From the downstream consumer structure shows: 70% of the terephthalic acid used to produce polyester fiber (80% of which is polyester); 15% for the production of bottle-grade polyester; 5% for the film-grade polyester, the remaining 10% For the production of engineering plastics and powder coatings and other products.
