Thepropylene oxide msika"Jinjiu" inapitirizabe kukwera kwake, ndipo msika unadutsa 10000 yuan (mtengo wa tani, womwewo pansipa).Kutengera msika wa Shandong mwachitsanzo, mtengo wamsika udakwera yuan 10500 ~ 10600 pa Seputembara 15, kukwera pafupifupi yuan 1000 kuchokera kumapeto kwa Ogasiti.Pa Seputembala 20, idabwereranso ku 9800 yuan.M'tsogolomu, gawo lothandizira likuyembekezeka kukula, nthawi yofunikira kwambiri sikhala yolimba, ndipo propylene oxide imasinthasintha mu 10000 yuan.
Kuchulukitsa kwa propylene oxide unit kuyambiransoko
Mu August, ma seti a 8 a propylene oxide units adasinthidwa ku China, kuphatikizapo mphamvu ya matani a 1222000 / chaka ndi kutaya kwathunthu kwa matani a 61500.Mu Ogasiti, linanena bungwe zoweta propylene okusayidi chomera anali 293200 matani, pansi 2.17% mwezi pamwezi, ndi mlingo magwiritsidwe ntchito anali 70,83%.
Mu Seputembala, Sinochem Quanzhou propylene oxide unit idatsekedwa kuti ikonzedwe, Tianjin Bohai Chemical, Changling, Shandong Huatai ndi mayunitsi ena adayambiranso motsatizana, ndipo gawo la Jinling lidachepetsedwa mpaka theka lantchito.Pakalipano, ntchito ya propylene oxide ili pafupi ndi 70%, yotsika pang'ono kuposa mu August.
M'tsogolomu, gawo la 100000 t/a la Shandong Daze lidzayambiranso kupanga kumapeto kwa September, ndipo Jincheng Petrochemical's 300000 t/a unit ikuyembekezeka kupangidwa kumapeto kwa September;Zomera za Jinling ndi Huatai zikubwereranso kupanga pang'onopang'ono.Mbali yogulitsira imakhala yowonjezereka, ndipo amalonda ndi otsika kwambiri.Zikuyembekezeka kuti msika wa propylene oxide uwonetsa kufooka kwapang'onopang'ono pakuwonjezeka kwa ndende, ndi chiopsezo chotsika.
Chithandizo cha propylene oxide yaiwisi chikuyembekezeka kukhala chovuta
Pakuti kumtunda zopangira propylene ndi madzi chlorine, ngakhale "Jinjiu" anayambitsa funde la kukwera msika, zikuyembekezeka kuti kudzakhala kosavuta kugwa kuposa kuwuka mu msika mtsogolo, zomwe zidzakhala zovuta kupanga chikoka champhamvu kwa. kunsi kwa mtsinje.
Mu Seputembala, mtengo wa propylene, zopangira zakumtunda, zidapitilirabe kugwedezeka, zomwe zidaperekanso chithandizo champhamvu pamsika wa propylene oxide.Wang Quanping, mainjiniya wamkulu wa Shandong Kenli Petrochemical Gulu, adati kuperekera kwa propylene kumakhalabe kolimba, komwe kumagwira ntchito bwino kumpoto chakumadzulo, chapakati ndi kum'mawa kwa China.Kuphatikiza apo, zida zina zokonzera kumunsi kwa propylene, monga Tianjian Butyl Octanol, Dagu Epoxy Propane, ndi Kroll Acrylonitrile, zayambiranso kumanga.Chifukwa chake, kufunikira kwa msika kwakwezedwa m'mwamba, mabizinesi a propylene akhala akugulitsa bwino, ndipo kutsika kochepa kwakweza mitengo ya propylene kukwera.
Kuchokera pakuwona ntchito yamagulu, mbali imodzi, Xintai Petrochemical ndi propylene units adayambiranso, koma zotsatira zake zinali zochepa chifukwa cha kuchedwa kwafupipafupi.Pa nthawi yomweyo, ena luso latsopano kupanga propane dehydrogenation kuti propylene mu Shandong anaikidwa ntchito zochepa kuposa kuyembekezera, ndi kotunga wonse anali ndi controllable.Kumbali ina, posachedwapa, mayunitsi ena akuluakulu kumpoto chakumadzulo atsekedwa kuti asamalire, ndipo kuyamba kwa propylene kumpoto chakumadzulo kwatsika mpaka 73.42%.Mayendedwe a katundu wa peripheral propylene watsika kwambiri.Kuphatikiza apo, zomera zina zakumpoto chakumadzulo zasungira kufunikira kwa propylene kwa kupanga kunja, ndipo kuperekedwa kwa peripheral propylene kwakhwimitsidwa kwambiri.
M'tsogolomu, kuchuluka kwa mabizinesi a propylene kumakhala kokhazikika, ndipo palibe chiyembekezo chakusintha kwakukulu pakuperekedwa kwa propylene.Madera ozungulira a Shandong ndi East China apitilizabe kukhala ndi zinthu zambiri.Mtsinje umakonda kufooka ndi mbale, kupondereza chidwi chogula cha propylene kunsi kwa mtsinje.Chifukwa chake, msika wamakono wa propylene umakhala wofooka komanso wosowa, koma octanol wakumunsi, propylene oxide, acrylonitrile ndi mafakitale ena awonjezera katundu wawo, ndipo mbali yofunikira yolimba ikadali ndi chithandizo.Zikuyembekezeka kuti mtengo wotsatira wa propylene udzasinthasintha pang'ono, ndikutsika pang'ono ndi kugwa.
Zina zopangira, chlorine yamadzimadzi, ndiyomwe imasewera kwambiri pamsika.Kugulitsa kwakunja kwazinthu zina zokonza zida zamafakitale akuluakulu kunachepa pang'ono, ndipo opanga ena m'chigawo chapakati cha Shandong anali osakhazikika, omwe adathandizira msika kuti upitirire kukwera pang'ono.Kutsikira kwa mphamvu yayikulu ku East China kwachira, kufunikira kwachepa, ndipo zida zina zatsekedwa kuti zikonzedwe.Kupereka kwachepa.Zomwe zili bwino pazakudya komanso zofunidwa zakwera kwambiri pamsika wa Shandong, zomwe zikupangitsa kuti msika uyambe kukwera.Meng Xianxing adati pakubwezeretsa zida zochepetsera kupanga komanso kuchuluka kwa zinthu, mtengo wamadzimadzi wa chlorine ukhoza kutsika m'nthawi yamtsogolo.
Kufunika kwa propylene oxide kumakhala kwaulesi ndipo kumakhala kovuta kuchita bwino munyengo zomwe zimakonda kwambiri
Polyether polyol ndiye chinthu chofunikira kwambiri chakumunsi cha propylene oxide komanso chopangira chachikulu cha polyurethane synthesis.Kuchulukirachulukira kwamakampani apanyumba a polyurethane kunsi kwa mtsinje, makamaka kupsinjika kwa msika wofewa wa thovu, ndikwambiri.
Meng Xianxing adanena kuti mu September, motsogozedwa ndi ndalama, msika wofewa wa polyether wofewa unanyamuka, ndipo makampani akuluakulu akupitirizabe kuthandizira msika, koma kutsika kwapansi kunali kochepa, ndipo pakati ndi m'munsi zinali zochepa.
Pakalipano, siponji yotsika pansi ikukwera pang'onopang'ono, mtengo wokwera pamwamba ukufunikabe kufalikira, zapakati ndi zotsika zimasunga chimbudzi ndikudikirira, ndipo msika wolimba ukupitirizabe kupepuka.M'tsogolomu, ngakhale kuti nkhani zoipa zenizeni sizinapangidwebe, opanga ambiri akusowabe malo chifukwa cha mtengo wa clamping, ndipo udindo wawo wothandizira zipangizo zopangira mtsinje ndi zochepa.
Kumbali inayi, msika wakumunsi wa thovu lolimba la polyether udakhalabe wokwera pang'onopang'ono, ndipo malo apakati ndi otsika adapitilizabe kugula pofunikira.Ngakhale kuti ntchito yonseyi inali yochepa kuposa nthawi yomweyi, idayenda bwino poyerekeza ndi gawo lachiwiri.Ngakhale kulowa "Jinjiu", palibe kusintha koonekeratu pakufuna kwa msika, ndipo fakitale imasankha kupanga kutengera zofuna.
M'tsogolomu, mabizinesi akumunsi amakhala akudikirira ndikuwona, ndipo kufunitsitsa kwawo kugula maoda atsopano ndikofala.Pamalo amalonda ofooka ndi ndalama, polyether yolimba ya thovu "Jinjiu" siikwanira kulowetsa mphamvu kumtunda.
