Ua piʻi ke kumu kūʻai o nā Nylon 6 Chips

I ka mahina i hala iho nei, ua puka mai kahi pōʻai o ke kumukūʻai no ka nylon 6 chips ma ka mākeke Kina.He pale pale ka lalo, a no ka paʻa ʻana o ka mīkini hoʻouna, ʻike ka upstream a me lalo i nā kūlana like ʻole.ʻO ka maikaʻi loa, hiki ke manaʻo ʻia he mākeke hoʻolālā.Piʻi hauʻoli ka uka, ʻoiai ʻo ka hale hana nylon 6 i kahi kūlana paʻakikī.

1. Nailon 6 chips a me FDY

Mai Pepeluali 1 a Malaki 1, ua hōʻike ʻia ka ʻikepili i hoʻokuʻu ʻia e China Fiber Network i ka upstream e like me ka benzene maʻemaʻe a me ka caprolactam, midstreamnylon 6 chips, downstream e like me ka nylon 6 a me ka wili huki piha (FDY) i hoʻonui ʻia e 34.13%, 29.89%, 21.43% a 22.47%, ʻo ka piʻi ʻana o nā ʻāpana o ka polymer nylon 6 he liʻiliʻi, a ʻoi aku ka kokoke i ka upstream, ʻoi aku ka nui o ka hoʻonui.

Mai ka hiʻohiʻona o ka loaʻa kālā, ua loaʻa ka ʻokoʻa o ke kumukūʻai o ka upstream caprolactam i kahi kiʻekiʻe hou i 19 mau mahina mai Mei 2019, a hiki i 7,700 yuan / ton, ka piʻi ʻana o kēlā me kēia mahina i 1,450 yuan / ton, a ua hoʻonui ʻia ka loaʻa kālā ma 22.95%.Ua hoʻonui ʻia ka ʻokoʻa ma waena o ka nylon 6 chips a me FDY e 100 yuan / ton, akā ua hāʻule ka ʻokoʻa ma waena o ka nylon 6 chips a me caprolactam e 150 yuan / ton, a ua hoʻonui ʻia ka pohō e 18,75%.

2. Kūkākūkā ma ka ʻoihana nylon 6 o Kina

No ka ʻoihana nylon 6 ma Kina, ua hoʻomaka ʻia kēia pōʻai o ka piʻi ʻana o nā kumukūʻai e ka emi ʻana o ka maʻi ahulau honua a me ka piʻi ʻana o nā kumukūʻai ma muli o ke kālā nui.Eia nō naʻe, ma ke ʻano o ka mīkini hoʻoili kumukūʻai, ʻoi aku hoʻi i ke ʻano o ke kālepa ʻoihana, ʻoi aku ka ikaika o nā ʻoihana caprolactam upstream, a ʻo ka hale hana polynylon 6 i kahi kūlana passive maikaʻi ʻole.

I nā makahiki, ua hoʻokomo pololei nā mea kanu caprolactam i nā laina hana polymerization hou.ʻAʻole hiki i ka downstream polymerization nylon 6 mea kanu ke hoʻokūkū me lākou ma ke ʻano o nā kumukūʻai hana, a ua ʻoki nui ʻia ko lākou wahi noho.ʻOi aku ka nui, ke hakakā nei kekahi mau ʻoihana i ke kaua kumukūʻai, ʻike pinepine ʻia ke kumukūʻai o nā chips a i ʻole ka haʻahaʻa ma mua o ka caprolactam.
