ʻO Styrene kahi mea waiwai nui kemika wai.He monocyclic aromatic hydrocarbon me ke kaulahao ʻaoʻao alkene a hoʻokumu ʻia ka ʻōnaehana conjugate me ke apo benzene.ʻO ia ka lālā maʻalahi a koʻikoʻi o nā hydrocarbons aromatic unsaturated.Hoʻohana nui ʻia ʻo Styrene ma ke ʻano he mea maka no ka hana ʻana i nā resins synthetic a me ka rubber.
ʻO Styrene kahi mea waiwai nui wai kemika, nona ka monocyclic aromatic hydrocarbon me ke kaulahao ʻaoʻao alkene a hana i kahi ʻōnaehana conjugated me ke apo benzene.He styrene hydrocarbon aromatic unsaturated "e lawe ana i ka lanahu aila a me ka hoʻopili ʻana i ka lāʻau a me ka plastic", a he mea koʻikoʻi ia no ka ʻoihana petrochemical.ʻO ke kahawai i uka o ka styrene he benzene a me ka ethylene, a ʻo ka lalo o ke kahawai he ʻano hoʻopuehu.ʻO nā huahana koʻikoʻi e pili ana i ka polystyrene foaming, polystyrene, ABS resin, synthetic rubber, unsaturated polyester resin a me styrene copolymers, a ua hoʻohana nui ʻia ka pahu i nā huahana plastik a me nā huahana synthetic.
ʻO 2010 ka hoʻonui ʻia ʻana o ka mana hana styrene honua, ʻoi loa i ka wā e piʻi ai ma kahi o 2.78 miliona tons o ka mana hana, ua kokoke ka ulu ʻana o ka huahana i 10%, ʻo ka mea nui ka honua ma Kina a hiki i nā huahana o lalo o styrene (terminal i hoʻohana ʻia i nā lako hale, kaʻa a me ʻO nā mea hana hale kūkulu hale) ʻai, i ka makahiki 2009 a me 2010, ʻoi aku ka koi o Kina no styrene ma luna o 15%.Ma hope o 2010, ua lohi iki ka ulu ʻana o ka mana hana styrene honua, a ma ka hopena o 2017, hiki i ka hiki ke hana styrene honua i 33.724 miliona tons.
Hoʻokumu nui ʻia ka mana hana styrene honua ma Asia Hikina, ʻAmelika ʻAmelika a me ʻEulopa Komohana, nona ka 78.9% o ka mana hana styrene honua.Eia kekahi, ʻo ka ʻāina ʻo Asia-Pākīpika ka 52 pakeneka o ka mana hana styrene honua.
Hoʻopuehu ʻia ke koi o lalo no ka styrene, a ʻo nā huahana hope loa he mau huahana plastik a me ka synthetic rubber.
Mai ke ao holoʻokoʻa i lalo koi o styrene i 2016, 37.8% styrene ua hoʻohana 'ia i ka polystyrene, 22.1% i ka huahuakai polystyrene, 15.9% i ABS resin, 9.9% i styrene butadiene rubber, 4.8% i unsaturated resin, etc.
Me ka piʻi ʻana o ka mana hana hale hou, ua emi mau ka nui o ka styrene import a me ka hilinaʻi lawe mai i nā makahiki i hala.
Wahi a ka ʻikepili kuʻuna, i ka makahiki 2018, ʻo nā ʻāina nui o ka styrene import o Kina ʻo Saudi Arabia, Iapana, South Korea, Singapore, etc. ke kumu nui loa o ka laweia mai.
Mai Iune 23, 2018, ua kau ke Kuhina Kālepa o Kina i nā dumping anti-dumping mai ka 3.8% a i ka 55.7% ma ka styrene i lawe ʻia mai ka Repubalika o Korea a me ʻAmelika Hui Pū ʻIa no ka manawa o ʻelima mau makahiki, e hopena ana i ka emi nui o ka. ka hapa o ka lawe ʻana mai o Kina mai ka Repubalika o Korea i ka hapa ʻelua o 2018, me Saudi Arabia a me Iapana i lilo i kumu kumu nui o ka lawe ʻana mai.
Me ka hana koʻikoʻi o nā refineries pilikino kūloko, e hoʻokomo ʻia ka nui o nā mana hana hou o styrene i Kina i ka wā e hiki mai ana.
I loko o ka manawa "13th Five-Year Plan", ua hoʻolaha ʻo Kina i nā papahana hoʻomaʻemaʻe pilikino a me nā hana hoʻohui petrochemical.I kēia manawa, ua ʻae ʻia ʻo Hengli, Sheng a me nā ʻoihana hoʻomaʻemaʻe ʻumi miliona a me ka hoʻohui ʻana i ka petrochemical e komo i ka wā kiʻekiʻe o ke kūkulu ʻana, a ʻo ka hapa nui o nā ʻoihana hoʻomaʻemaʻe a me nā ʻoihana petrochemical e kākoʻo i nā mea hana styrene downstream.
