ʻO kamakeke propylene oxideUa hoʻomau ʻo "Jinjiu" i kona piʻi ʻana ma mua, a ua haki ka mākeke ma ka paepae 10000 yuan (ke kumu kūʻai ton, ʻo ia ka mea ma lalo). Ke lawe nei i ka mākeke Shandong ma ke ʻano he laʻana, ua piʻi ke kumukūʻai mākeke i 10500~10600 yuan ma Kepakemapa 15, ma kahi o 1000 yuan mai ka hopena o ʻAukake. Ma ka lā 20 o Kepakemapa, ua hāʻule hou i ka 9800 yuan. I ka wā e hiki mai ana, ua manaʻo ʻia e ulu ka ʻaoʻao hoʻolako, ʻaʻole ikaika ka manawa kiʻekiʻe o ka noi, a ʻo ka propylene oxide fluctuates i 10000 yuan.
E hoʻonui hou i ka lako propylene oxide
I ʻAukake, ua hoʻoponopono hou ʻia ka huina o 8 mau pūʻulu propylene oxide ma Kina, e pili ana i ka nui o 1222000 tons / makahiki a me ka pau ʻana o 61500 tons. I ʻAukake, ʻo 293200 tons ka hoʻopuka ʻana o ka mea kanu propylene oxide home, i lalo o 2.17% mahina ma ka mahina, a ʻo ka nui o ka hoʻohana ʻana he 70.83%.
I Kepakemapa, ua pani ʻia ʻo Sinochem Quanzhou propylene oxide no ka mālama ʻana, ua hoʻomaka hou ʻia ʻo Tianjin Bohai Chemical, Changling, Shandong Huatai a me nā ʻāpana ʻē aʻe, a ua hoʻemi ʻia ʻo Jinling unit i ka hapalua o ka hana. I kēia manawa, kokoke i ka 70% ka hana o ka propylene oxide, haʻahaʻa iki ma mua o ʻAukake.
I ka wā e hiki mai ana, e hoʻomaka hou ana ka hana 100000 t/a Shandong Daze i ka hopena o Kepakemapa, a ua manaʻo ʻia e hoʻokomo ʻia ka hui 300000 t/a Jincheng Petrochemical i ka hopena o Kepakemapa; Ke hoʻi nei nā mea kanu ʻo Jinling a me Huatai i ka hana i kēlā me kēia pae. ʻO ka ʻaoʻao hoʻolako ka mea nui, a ʻoi aku ka bearish o nā mea kālepa. Manaʻo ʻia e hōʻike ka mākeke propylene oxide i kahi ʻano nāwaliwali o ka stalemate ma lalo o ka piʻi ʻana o ka hoʻolako ʻana, me ka liʻiliʻi o lalo.
Manaʻo ʻia he paʻakikī ke kākoʻo o ka propylene oxide maka
No ka propylene a me ka wai chlorine o luna, ʻoiai ʻo "Jinjiu" i hoʻomaka i ka nalu o ka piʻi ʻana o ka mākeke, ua manaʻo ʻia ʻoi aku ka maʻalahi o ka hāʻule ʻana ma mua o ka piʻi ʻana i ka mākeke e hiki mai ana, he mea paʻakikī ke hana i kahi huki ikaika no ka mea. ka lalo.
I ka mahina o Kepakemapa, ua hoʻomau ka piʻi ʻana o ke kumukūʻai o propylene, ka mea maka mua, i ka haʻalulu, a ua hāʻawi pū i ke kākoʻo ikaika no ka mākeke propylene oxide. Ua ʻōlelo ʻo Wang Quanping, ka ʻenekini nui o Shandong Kenli Petrochemical Group, ua paʻa mau ka lako propylene home, me ka hana ʻike ma ke komohana ʻākau, waena a me Kina hikina. Eia kekahi, ua hoʻomaka hou kekahi mau mea mālama i lalo o ka propylene, e like me Tianjian Butyl Octanol, Dagu Epoxy Propane, a me Kroll Acrylonitrile. No laila, ua hoʻonui ʻia ka makemake o ka mākeke, ua kūʻai maikaʻi nā ʻoihana propylene, a ua hoʻonui ka haʻahaʻa haʻahaʻa i nā kumukūʻai propylene i luna.
Mai ka hiʻohiʻona o ka hana ʻana, ma kekahi ʻaoʻao, ua hoʻomaka hou ʻia nā ʻāpana ʻo Xintai Petrochemical a me propylene, akā ua kaupalena ʻia ka hopena ma muli o ka lohi pinepine. Ma ka manawa like, ua hoʻokomo ʻia kekahi mau mana hana hou o ka propane dehydrogenation i propylene ma Shandong i ka hana ma mua o ka mea i manaʻo ʻia, a ʻo ka lako holoʻokoʻa ua hiki ke hoʻomalu. Ma ka ʻaoʻao ʻē aʻe, i ka wā e hiki mai ana, ua pani ʻia kekahi mau ʻāpana nui ma ke komohana akau no ka mālama ʻana, a ua hāʻule ka hoʻomaka ʻana o ka propylene ma ke komohana ʻākau i 73.42%. Ua emi nui ke kaapuni o nā waiwai propylene peripheral. Eia kekahi, ua mālama kekahi mau mea kanu komohana komohana i ka noi propylene no ka hana ʻana i waho, a ua hoʻopaʻa nui ʻia ka lako o ka propylene peripheral.
I ka wā e hiki mai ana, paʻa ka ukana o nā ʻoihana propylene, a ʻaʻohe manaʻo o nā loli nui i ka lako propylene. E mālama mau ana nā ʻāpana o Shandong a me Kina Hikina i kahi lako paʻa. E hoʻonāwaliwali i lalo me ka pā, e kāohi ana i ka hoihoi kūʻai o propylene i lalo. No laila, ʻo ka mākeke propylene i kēia manawa aia i kahi kūlana o ka hāʻawi ʻana a me ka koi, akā ʻo ka octanol downstream, propylene oxide, acrylonitrile a me nā ʻoihana ʻē aʻe i hoʻonui i kā lākou ukana, a ʻo ka ʻaoʻao koi koʻikoʻi ke kākoʻo. Ua manaʻo ʻia ʻo ke kumukūʻai propylene ma hope mai e loli ma kahi ākea, me ka piʻi a hāʻule liʻiliʻi.
ʻO kekahi mea maka, ka chlorine wai, he mea pāʻani nui i ka mākeke. ʻO ka nui o nā kūʻai kūʻai o waho o kekahi mau lako mālama o nā ʻoihana nui i emi iki, a ʻo kekahi mau mea hana ma waena o Shandong ʻaʻole paʻa, e kākoʻo ana i ka mākeke e hoʻomau i ka piʻi ʻana i kahi ākea. Ua hoʻi hou ka lalo o ka ikaika nui ma Kina Hikina, ua maʻalahi ke koi, a ua pani ʻia kekahi mau mea hana no ka mālama ʻana. Ua emi ka lako. ʻO ke kūlana maikaʻi ma ka ʻaoʻao hoʻolako a me ka noi ua hoʻonui ʻia i ka piʻi ʻana o ka mākeke Shandong, e alakaʻi ana i ka neʻe ʻana o ka mākeke holoʻokoʻa o ka mākeke. Ua ʻōlelo ʻo Meng Xianxing, me ka hoʻihoʻi ʻana o nā mea hoʻohaʻahaʻa hana a me ka hoʻonui ʻana o ka lako, hiki ke emi ke kumu kūʻai o ka chlorine wai i ka wā ma hope.
ʻO ke koi no ka propylene oxide he lohi a paʻakikī hoʻi e ulu i nā kau kiʻekiʻe
ʻO ka polyether polyol ka mea nui loa o lalo o ka propylene oxide a me ka mea nui no ka polyurethane synthesis. ʻO ka overcapacity holoʻokoʻa o ka ʻoihana polyurethane i lalo o ka hale, ʻoi aku ka nui o ke kaomi ʻana o ka mākeke foam palupalu.
Ua ʻōlelo ʻo Meng Xianxing i ka mahina ʻo Kepakemapa, i alakaʻi ʻia e nā kumukūʻai, ua piʻi ka mākeke polyether foam palupalu, a ua hoʻomau ka ʻoihana nui i ke kākoʻo ʻana i ka mākeke, akā ʻo ka hana o lalo he awelika, a ʻo ka waena a me ka haʻahaʻa haʻahaʻa.
I kēia manawa, ke piʻi mau nei ka ʻōhuhi o lalo, pono e hoʻouna hou ʻia ke kumukūʻai o uka, mālama ka waena a me lalo i ka ʻai ʻana a me ke kali ʻana, a ke hoʻomau nei ka mākeke paʻa. I ka wā e hiki mai ana, ʻoiai ʻaʻole i hoʻokumu ʻia ka nūhou maikaʻi maoli, nui nā mea hana i nele i ka wahi ma muli o ka hoʻopaʻa ʻana i ke kumukūʻai, a ua kaupalena ʻia kā lākou kuleana i ke kākoʻo ʻana i nā mea maka.
Ma ka ʻaoʻao ʻē aʻe, ua hoʻomau ka mākeke polyether foam paʻa i lalo i kahi ʻano piʻi i luna, a hoʻomau ke kūʻai ʻana o ka waena a me lalo ma ke koi. ʻOiai ʻoi aku ka haʻahaʻa o ka hana holoʻokoʻa ma mua o ka manawa like, ʻoi aku ka maikaʻi ma mua o ka hapaha ʻelua. ʻOiai ke komo ʻana i "Jinjiu", ʻaʻohe loli ʻike o ka noi mākeke, a hoʻoholo ka hale hana i ka hana ma muli o ke koi.
I ka wā e hiki mai ana, ke kali nei nā ʻoihana i lalo a ʻike, a ʻo ko lākou makemake e kūʻai i nā kauoha hou he laulā. Ma ke kūlana o ke kālepa nāwaliwali a me ka hoʻopukapuka kālā, ʻaʻole maikaʻi ka polyether foam paʻakikī "Jinjiu" e hoʻokomo i ka ikaika i ka upstream.
