一.ʻO ka ʻaoʻao hoʻolako: ka mana hana hale hou a i ʻole e hoʻololi i ke kumu hoʻolako honua

Mai ka mākeke nylon honua, ʻo ka nylon 6 a me ka nylon 66 ka helu no ka ʻoi aku ma mua o 95% o ka nui o ka mana hana a me nā huahana.Wahi a ka hōʻike IHS, i ka makahiki 2020 ka mana o ka honua nylon 6 o 10.52 miliona tons / makahiki, nylon 66 kaha o 3.17 miliona tons / makahiki.ʻO ka home nylon 6 no ka mea ua ʻike ʻia ka caprolactam maka, ka ulu wikiwiki o ka hiki ke hana i nā makahiki i hala aku nei, ʻo ka home nylon 6 ka mana hana ma 2020 a hiki i 6.47 miliona tons / makahiki, e helu ana ma kahi o 62% o ka mana hana honua. ʻO ka mana hana o nā ʻoihana ʻumikūmālua kiʻekiʻe i ʻoi aku ma mua o 36%, ka hapa nui o Kina Hikina, Kina Hema a me nā wahi i kūkulu ʻia.Wahi a kā mākou huahelu Huaʻan Chemical, aia he 2.78 miliona mau tona o ka mana hana hou i ka wā e hiki mai ana.I kēia manawa, hana nui ka nylon home 6 i nā mea fiber, ʻo ka wā e hiki mai ana me ka hoʻonui ʻana i ka mana hana i alakaʻi ʻia i ka hoʻokūkū ikaika, ʻoi aku ka nui o nā mea hana e komo i nā ʻenekinia plastics a me nā wahi kiʻekiʻe i hoʻohui ʻia.

ʻO ka mana o ka nylon 66 ua ʻoi aku ka liʻiliʻi o ka nylon 6. I kēia manawa, ʻo ka mana hana hale o ka nylon 66 e pili ana i 600,000 tons / makahiki, ma muli o ka synthesis o kekahi o ka monomer adipamide maka waiwai adiponitrile lōʻihi monopoly i loko o nā lima o kahi. kakaikahi na mea hana haole.I nā makahiki i hala iho nei, ʻo ka localization o adiponitrile breakthroughs, manaʻo ʻia e hoʻonui wikiwiki ʻia ka hoʻolālā ʻana o kēia manawa a ma lalo o ke kūkulu ʻana i ka nylon 66 ka mana hana o 1.26 miliona tons / makahiki.

二.ʻO ka ʻaoʻao koi: ʻO ka ulu ʻana o ka mākeke mākeke o Kina

Ma muli o ke ʻano o ka nylon 6 a me ka nylon 66 ʻokoʻa, ʻokoʻa ke ʻano o ka nylon 6 a me ka nylon 66.ʻO 71% o ka nylon 6 no nā filament textile, nā filament ʻoihana a me nā kīhāpai ʻē aʻe, 29% no nā resins ʻenekinia.ʻOiai ʻo 59% o ka nylon 66 e hoʻohana ʻia no nā resins engineering.I ka wā e hiki mai ana, me ka boom i loko o nā plastics, ua manaʻo ʻia e hoʻohana hou ʻia ka nylon 66 a me ka nylon 6 no nā resins engineering.

Ma waho aʻe o ka Kina ka nylon koi makeke, mai ke koena o ke ao nei ka nylon 6 a me ka nylon 66 hoʻohana hana, kokoke eono makahiki o global nylon 6 hoʻohana ma 2.5 miliona tons / makahiki i luna a me lalo, nylon 66 hoʻohana i 1.5 miliona tons / makahiki fluctuations , ua manaʻo ʻia ka wā e hiki mai ana ma hope o ka hoʻihoʻi ʻana o ka maʻi maʻi e loaʻa i kahi pae o ka rebound, akā ma muli o ke kumu kūʻai o ka nylon i kēia manawa ma nā ʻāina ʻē aʻe i hoʻomohala ʻia ma lalo o ka helu penetration ua ʻoi aku ka kiʻekiʻe, ʻo ke ʻano lōʻihi o ka ulu lohi, ka wā e hiki mai ana. ulu Ka noi e nānā iā Kina.

E pili ana i ka hana mākeke honua, wikiwiki ka ulu ʻana o ka mākeke nylon ma Kina.Mai 2015 a 2019, ua hoʻonui ʻia ka hoʻohana ʻana i ka nylon 6 e 1.08 miliona tonnes / makahiki, me ka awelika o ka ulu ʻana o ka makahiki he 9.7%, ʻoiai ka maʻi maʻi e pili ana i ka noi ma 2020, ua hāʻule ka ʻai ʻana e 4.4% wale nō (9.6% i ke koena o ka honua) ;i ka manawa like, ua hoʻonui ʻia ka hoʻohana ʻana o ka nylon 66 e 44,000 tonnes / makahiki, kahi nui e like me ka ulu ʻana ma nā wahi ʻē aʻe o ka honua.Me ka hoʻonui ʻana i ka hiki ke hana i nā mea maka, ka hoʻemi ʻana i ke kumukūʻai, a me ka hoʻomaikaʻi ʻana i ke kūlana o ka nohona o nā kānaka a me ka pono o nā waiwai kiʻekiʻe, ʻo nā makahiki he ʻumi e hiki mai ana e manaʻo ʻia e ulu nui i ka hoʻohana ʻana i ka home o nylon 6 a me ka nylon 66 .
