[Alakaʻi]: I ka hopena o Iune, ua hiki ke pani ʻole ʻia o nā lako mākeke propylene ma hope o kekahi, i mea maikaʻi i ka ʻaoʻao hoʻolako, ʻoiai ua piʻi ka hoihoi o nā huahana o lalo, a ua pau ke kumukūʻai o ka mākeke i ka hāʻule ʻana, mai Iulai 14, ka mainstream. ʻO ke kumu kūʻai o ka mākeke propylene Shandong he 6480-6500 yuan / ton, a ʻo ka hana nui o ka mākeke East China he 6350-6350 yuan / ton.

I kēia pōʻai, ua pau ka hāʻule ʻana o ka mākeke propylene home, a ʻo nā kumu e kākoʻo ana i ka rebound o ka mākeke aia ma nā kumu kumu o ka lako a me ke koi. ʻO Macro, nā kumukūʻai aila honua i piʻi, nā kumu maikaʻi nui: maikaʻi ka ʻikepili inflation o ʻAmelika Hui Pū ʻIa, ʻo ka Federal Reserve e hoʻomau i ka hoʻokiʻekiʻe ʻana i ka uku paneʻe i nāwaliwali, a me nā ʻoki hana hou a Saudi Arabia i lawe mai i ka hoʻomau o ka lewa maikaʻi, i ka makeke. I ka manawa like, ʻaʻole i hoʻomaka hou ʻia ke kaʻa kaʻa o Qingdao Jinneng, Wangtong, a me Zhenghe propylene ma ka ʻāina, ʻoiai ʻaʻole i hoʻomaka hou ʻia ka mīkini kaʻa kaʻa mua, a ke kū nei ka lako i ka mākeke me kekahi kākoʻo, a me ka nui o ka PDH production rate. ʻO 69.79% e like me 14 mau lā, ʻo ia ka 0.2% haʻahaʻa ma mua o ka pōʻai mua. Me ka hāʻule ʻana o ka hana propylene, ʻaʻole kiʻekiʻe ka helu o nā ʻoihana hana propylene ma ke ʻano holoʻokoʻa, ʻoi aku ka maikaʻi o ke kumukūʻai hāʻawi, ʻoi aku ka maikaʻi o ke kūʻai ʻana i lalo, a ʻoi aku ka maikaʻi o ka lewa kālepa holoʻokoʻa.

Ma kēia pōʻai, ua hui pū ʻia nā kaʻina hana ʻekolu o ka propylene, a ʻoi aku ka maopopo o ka loaʻa ʻana o ka propane dehydrogenation i propylene. Ma kekahi ʻaoʻao, ke hāʻule mau nei ke kumukūʻai kiko o propane i kēia pae, a ma kekahi ʻaoʻao, ikaika ke kumu kūʻai o propylene monomer, e hāʻawi ana i kahi hoʻoikaika i ke ʻano waiwai. Ua emi iho ka waiwai o ka naphtha a me ka methanol i propylene, a ua emi nui ka waiwai o ka methanol i ka propylene, a ua pili nui ia e ka piʻi ʻana o ke kumu kūʻai o ka methanol maka, i keakea i ka loaʻa. Naphtha i ka propylene kaʻina waiwai makemake e emi mai ka pule hope loa, ka mea nui influencing kumu o ka naphtha kumu kūʻai haiki i luna, akā, ma luna o ka loaʻa kālā hookuke kauo i hanaia, ua manaoia e pōkole-makahiki propylene waiwai volatility au, lohi uku kokoke i ka makeke. kumu kūʻai o nā mea maka.

I ka wā pōkole, ma ka ʻaoʻao hoʻolako, me ka hoʻomaka hou ʻana o nā mea PDH ma Shandong, ua hoʻonui mālie ʻia ka ukana o ka mea hou i hoʻokomo ʻia i ka hana mua, a ua manaʻo ʻia e hoʻonui ʻia ka lako propylene i kēia manawa, akā ke kaʻa kaʻa o ka manawa. E hāʻawi nā mea hana pilikino ma Shandong i kahi hoʻoikaika i ka mākeke. ʻO ka ʻaoʻao koi, i kēia manawa, ʻoi aku ka ikaika o ka mākeke polypropylene, ʻoi aku ka maikaʻi o ka pauda, ​​pono e kūʻai nui nā hale kūʻai i lalo, ʻoiai ʻo ka pule aʻe PO, ua manaʻo ʻia e hoʻomaka hou ka hale hana acrylonitrile, ua manaʻo ʻia ʻo ka propylene pōkole. Hiki ke piʻi iki ka mākeke, akā ua kaupalena ʻia ka piʻi ʻana, e hahai pono i ka hoʻomaka hou ʻana a me ka hoʻouna ʻana o nā mea hana propylene.

ʻO ka ʻaoʻao koi, ke ʻano o ka mākeke polypropylene i ka pōʻai, ikaika ke kākoʻo ʻaoʻao koi, ua hāʻule ke kumu kūʻai propylene pre-stack i ka haʻahaʻa, ua hoʻonui ʻia ka pālahalaha ma waena o propylene a me PP, ua hoʻonui nui ʻia ka waiwai o ka hale hana i lalo, ua ʻohi mālie ʻia ka hoihoi kūʻai. piʻi i luna, alakaʻi i ka hoʻouna ʻana i nā ʻoihana propylene, ʻoi aku ka haʻahaʻa o ka waihona waiwai, kākoʻo i nā kumukūʻai propylene.
