I kēia mau lā, ua piʻi ke kumukūʻai o nā huahana kemika: Nui nā ʻano a me nā pae nui. I ʻAukake, ua hoʻomaka ke kumukūʻai o nā huahana kemika. Ma waena o nā kumukūʻai huahana kemika 248 a mākou i nānā ai, ua hoʻonui ʻia nā huahana 165 i ke kumukūʻai me ka piʻi ʻana o 29.0%, a he 51 wale nō nā huahana i hāʻule i ke kumu kūʻai me ka awelika o ka emi ʻana o 9.2%. I waena o lākou, ua piʻi nui nā kumukūʻai o MDI maʻemaʻe, butadiene, PC, DMF, styrene a me nā huahana ʻē aʻe.

ʻO ka noi no nā huahana kemika maʻamau ʻelua mau kau kiʻekiʻe, ʻo ia hoʻi ʻo Malaki-ʻApelila ma hope o ka Spring Festival a me Kepakemapa-ʻOkakopa i ka hapa lua o ka makahiki. ʻO ka ʻikepili mōʻaukala o ka China Chemical Product Price Index (CCPI) mai 2012 a 2020 e hōʻoia pū ana i ke kānāwai o ka hana o kēia ʻoihana. A e like me kēia makahiki, ua hoʻomau ka piʻi ʻana o nā kumukūʻai huahana mai ʻAukake, a ua komo i kahi makahiki o ka hoihoi ʻole i Nowemapa, ʻo 2016 a me 2017 wale nō i alakaʻi ʻia e nā hoʻoponopono ʻaoʻao.

He kuleana koʻikoʻi nā kumukūʻai aila ma ke kumu kūʻai o nā huahana kemika. ʻO ka maʻamau, piʻi a hāʻule nā ​​kumukūʻai o nā huahana kemika e like me ka loli ʻana o nā kumukūʻai aila. Eia naʻe, ma ke kaʻina o ka piʻi ʻana o ke kumukūʻai o nā huahana kemika, ua mau ke kumukūʻai o ka aila maʻemaʻe, a ʻoi aku ka haʻahaʻa o nā kumukūʻai aila i kēia manawa ma mua o nā kumukūʻai i ka hoʻomaka ʻana o ʻAukake. Ke nānā nei i hope i nā makahiki 9 i hala iho nei, ua hoʻololi nui ke kumu kūʻai o nā huahana kemika a me ka aila ʻaila he 5 mau manawa wale nō, ʻoi aku ka nui o ka wā haʻalulu a i lalo paha, a ua piʻi nā kumukūʻai o ka aila maʻemaʻe aʻo nā kumukūʻai o nā huahana kemika e mau ana. a i ʻole i lalo. ʻO kēia makahiki wale nō ke piʻi nui ʻana o ke kumukūʻai o nā huahana kemika, ʻoiai ke piʻi nei ke kumukūʻai o ka aila maʻemaʻe. Ma lalo o ia mau kūlana, ʻo ka piʻi ʻana o nā kumukūʻai huahana kemika i hoʻonui nui i ka loaʻa kālā o nā ʻoihana pili.

ʻO nā hui kemika kekahi o nā loulou i ke kaulahao ʻoihana, a ʻo ka hapa nui o kā lākou upstream a i ʻole nā ​​​​mea kūʻai aku he hui kemika. No laila, ke piʻi aʻe ke kumukūʻai huahana o ka ʻoihana A, e piʻi pū ke kumukūʻai o ka ʻoihana B, ʻo ia ka ʻoihana o lalo. I mua o kēia kūlana, ʻoki ka hui B i ka hana ʻana a hoʻopaneʻe paha i ka hana e hōʻemi i ke kūʻai ʻana, a i ʻole e hoʻokiʻekiʻe i ke kumukūʻai o kāna mau huahana ponoʻī e hoʻololi i ke kaomi o ka piʻi ʻana o nā kumukūʻai. No laila, inā hiki ke piʻi ke kumukūʻai o nā huahana o lalo he kumu nui ia no ka hoʻoholo ʻana i ka hoʻomau o ka piʻi ʻana o ke kumukūʻai o nā huahana kemika. I kēia manawa, ma nā kaulahao ʻoihana he nui, ua hoʻomaka ke kumukūʻai o nā huahana kemika e laha mālie.

No ka laʻana, ʻo ke kumu kūʻai o ka bisphenol A ke piʻi nei i ke kumu kūʻai o PC, ʻo ka metala silicon ke kumu kūʻai o ka silicon organik, ka mea e hoʻokuʻu ai i ke kumukūʻai o nā mea hoʻohui a me nā huahana ʻē aʻe. ʻO ke kumu kūʻai o ka MDI maʻemaʻe a me ka PTMEG e alakaʻi i ke kumukūʻai o spandex.

Ma waena o nā kumukūʻai huahana 248 a mākou i nānā ai, ʻoi aku ka haʻahaʻa o nā kumukūʻai huahana 116 ma mua o ke kumukūʻai ma mua o ke ahulau; i hoʻohālikelike ʻia me ka manawa like i ka makahiki i hala, ua haʻahaʻa nā kumukūʻai huahana 125 ma mua o ka manawa like i ka makahiki i hala. Hoʻohana mākou i ke kumukūʻai maʻamau o nā huahana ma 2016-2019 e like me ke kumukūʻai waena, a ʻoi aku ka haʻahaʻa o nā kumukūʻai huahana 140 ma mua o ke kumukūʻai waena. I ka manawa like, ma waena o nā laha huahana kemika 54 a mākou i ʻimi ai, ʻoi aku ka haʻahaʻa o 21 ma mua o nā laha ma mua o ke ahulau; inā hoʻohālikelike ʻia me ka manawa like o ka makahiki i hala, ʻoi aku ka haʻahaʻa o 22 huahana ma mua o ka manawa like o ka makahiki i hala. Hoʻohana mākou i ka hoʻolaha huahana 2016-2019 ma ke ʻano he pālahalaha waena, a ʻoi aku ka haʻahaʻa o 27 huahana ma mua o ka pālahalaha waena. Kūlike kēia me nā hualoaʻa ʻikepili makahiki-ma-makahiki a me ke kani-ma-hahā.
