Shanghai Daoqin Plastics Co., Ltd.

         using/adopting caprolactam raw materials polymerization made nylon 66, not only technology can 行, also tool has 一定 经济 property. meanwhile, for caprolactam production enterprise 说, 该路线不 can ratio development nylon 6 polymerization filament more tool has outlook/prospects. in 10 month 10 day will 于威海举行 nylon mono technology and market forum upper, published caprolactam raw materials made nylon 66 初步 can property report, for its property, use property 一探究竟.

         new raw materials separation 三步走

         nylon 66 由 hexamethylenediamine and adipic acid polycondensation to, caprolactam raw materials polymerization nylon 66 is caprolactam made hexamethylenediamine rear, again and adipic acid polycondensation.

         caprolactam made hexamethylenediamine 需经历 below/following reaction process: 第一步 caprolactam and gas 发生氨化开 ring reaction, 打开C-N键, ring separation ring formed separation formed 6-氨基己酰 amine;第二步6-氨基己酰 amine water remove oxygen 原子, formed 6-氨基己腈;第三步6-氨基己腈 and hydrogen gas add hydrogen reaction obtain hexamethylenediamine.

         Toray company 于1965 year will caprolactam method made hexamethylenediamine industrial 化, main/primary used for waste raw materials recycled utilizing, nylon 6 factory recycling caprolactam product or waste nylon is raw materials.

         technology more tool property

         according to raw materials caprolactam most high price 13800元(吨价, lower 同)核算, caprolactam made hexamethylenediamine production cost is 2.5 10,000 yuan, if caprolactam crystallization combined formed hexamethylenediamine, hexamethylenediamine production cost again reduce 800~1000元, is 2.4 10,000 yuan. 该路线 caprolactam raw materials can full using/adopting waste product, if raw materials caprolactam content low, rear amount very large, need separation formed separation relatively more.

         caprolactam is raw materials made hexamethylenediamine, again and adipic acid polycondensation, to nylon 66 production cost is 1.9 10,000 yuan, versus ratio currently nylon 66 market price 2.3 10,000 yuan, also has 4000元 profit. year upper semi year caprolactam most high profit 3800元 left right, profit in 2325元 left right, relatively year decrease/reduce 约29.5%, this is according to raw materials caprolactam most high price 估算. can 看出, caprolactam made hexamethylenediamine profit ratio mono pure production caprolactam profit need high.

        而随 caprolactam production capacity 剩, price lower slip, caprolactam made hexamethylenediamine, nylon 66 经济 property more add obvious. year upper semi year caprolactam 均价13253元, year 同期均价16105元, relatively year fall 17.7% left right.

        开辟 nylon 66 polymerization 一体化

         technology 路线确定 rear, market is property factors. currently inner nylon 6 以民 use clothing/apparel fiber is 主, nylon 66 集 in industrial filament and other industry use fiber field/area, in carpet filament field/area has relatively good growth 空间. 恒申, 锦江, cationic and other nylon 6 切 sheet/slice, filament production enterprise positive in toward upper expand 张, upstream and downstream 一体化进程 accelerated, ring ketone — caprolactam — polymerization —纺 filament industry chain strip/profile positive in formed 并进一步 add deep.

         although 一体化 is direction, is mono caprolactam production enterprise toward upper nylon 6 polymerization, filament development, its technology, market 积累都不如 lower fiber enterprise more tool advantages. again add upper currently nylon 6 产需失衡, lower slip, 据国家 statistics statistics, year upper semi year 锦纶(main/primary is nylon 6) output/production volume is 233.62 10,000 tons, year-on-year growth 14.18%, upper semi year profit is 16.5 100 million yuan, year-on-year decrease/reduce 18.5%.

         in addition, more year due to raw materials ——己二腈“卡脖子”, made nylon 66 production and application, has 经 充 separation competition nylon 66 industry also formed advantages enterprise. therefore mono caprolactam production and its toward lower nylon 6 polymerization 延伸, 不如往 nylon 66 polymerization 延伸, formed caprolactam — nylon 66 polymerization 一体化, caprolactam — nylon 6 polymerization 一体化 enterprise, again toward nylon 66 polymerization 方面延伸, long caprolactam industry chain, formed nylon 6 — nylon 66 polymerization 一体化 “ di 龙”驱动集群.
