Hoʻohui kumu kūʻai PS me ka styrene maka

[Introduction] I ka makahiki 2022, ua hahai ka mākeke PS holoʻokoʻa ma Kina i ka loiloi o ke kumukūʻai, no laila ʻoi aku ka ikaika o ke kumukūʻai o PS me ka styrene maka, a ua hōʻea kāna coefficient correlation i 0.97 mai 2022, kahi i hoʻopili nui ʻia.I ka manawa like, ʻo ka pilina ma waena o ka ʻikepili hāʻawi a me ke kumukūʻai PS he mea maikaʻi ʻole, a ʻo ka coefficient correlation ʻo -0.79, e hōʻike ana i kahi pilina.

Mai ka hoʻopili ʻana i ka hoʻopili ʻana, ʻo ka hoʻopuka PS a me ke kumukūʻai o kēlā me kēia mahina ma ka hapa mua o ka makahiki i hoʻopili maikaʻi ʻia, a ʻo ka coefficient correlation -0.79, e hōʻike ana i ka hoʻohui ʻana i ka piʻi ʻana o ke kumukūʻai ma ka mākeke PS i ka ʻO ka hapa mua o ka makahiki, ua nui ka hopena o ka emi ʻana o ka huahana i ke kākoʻo kumukūʻai.E noʻonoʻo ana i ka ʻikepili hoʻolako ma ka ʻaoʻao kumukūʻai o ka hopena o ka hoʻopili maikaʻi ʻole.

I ka makahiki 2022, ua wehe ʻia ka hana PS a Kina i kahi kiʻekiʻe a haʻahaʻa loa, e hōʻike ana i kahi hiʻohiʻona i lalo ma ke ʻano holoʻokoʻa, ʻoi aku hoʻi i Iune a me Iulai, i hōʻea i kahi haʻahaʻa haʻahaʻa ʻelua mau makahiki, me ka hopena ma lalo o 230,000 tons.Eia nō naʻe, ʻo ka waihona mana o kēia manawa he 1.02 miliona mau kiʻekiʻe ma mua o ka manawa like ma 2021, he piʻi o 27%.I Iulai, China PS hana 223700 tons, mahina-ma-mahina -2.27%, makahiki-ma-makahiki -11.89%;He 1.9818 miliona tons ka huina hoonui, +13.11% makahiki ma ka makahiki.I loko o ka mahina, ʻo ka hapa nui o nā waiwai o ka ʻoihana i loko o ke ʻano maikaʻi ʻole, a ua nui ka nui o ka hoʻemi ʻana o nā mea hana, e like me CITIC Guoan, Zhenjiang Qimei, Yashida, Shanghai Secco, Ningbo Taichua, Ineos Benling, Tianyuan, Xinghui, XinZhongmei , Saibaolong, Baosheng, Haoyuan, Lanhua, Jade Emperor, etc. Ua hoʻomaka hou a hoʻonui ʻia kekahi mau ʻāpana, e like me Ningbo Taichua, Guangdong Xinghui a me Ningbo Liwan.

ʻO ka pilina maikaʻi ʻole ma waena o ka ʻikepili hāʻawi a me nā kumukūʻai PS hiki ke lilo i mea kaulana, ʻoiai ke emi nei ka pilina maikaʻi me nā kumukūʻai, me ka hopena o nā hoʻonohonoho hou e hiki mai ana ma ke kahawai i ka hapa lua o 2022.
