Kutsogola: Kuyambira mu Seputembala, msika wa propylene oxide wadziko lonse wawonetsa kukwera kokhazikika, kumayambiriro kwa mwezi, magulu onse pamsika ali ndi chiyembekezo cha nyengo ya "golide nine" pachimake, msika wapitiliza kukwera ndi kukwera, koma wakwera kufika pa 9550-9670 yuan/tani (fakitale yosinthira malo ya Shandong), msika wasanduka wovuta, mpaka pamlingo wina, wagunda chidaliro cha makampani, kumapeto kwa sabata yatha pambuyo pa kuchepa koyenera kwa cyC, chifukwa cha mtengo wowonekera wa kukoka, Msika unasiya kugwa mwachangu ndipo unayambitsa msika wina wokwera, kuyambira pa Seputembala 15, kufika pa 9650-9750 yuan/tani, kufika pachimake mu theka lachiwiri la chaka, ndipo kukula konse kunachepa.

Choyamba, kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito popereka zinthu kwawonetsa kuti zinthu zikuyenda bwino.

Pakati pa Seputembala, kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito pamsika wa propylene oxide m'nyumba nthawi zonse kwakhala kotsika pafupifupi 60% -65%, ndipo zida zambiri monga Jincheng Petrochemical, Taixing Yida, Wanhua Phase I, Tianjin Bohua zili mu mkhalidwe woyimitsa magalimoto, kuphatikiza kukonza kwakanthawi kochepa ndi kuchepetsa zida zazikulu monga Xinyue ndi Jiahong, ndi zina zotero, kupezeka kwa msika ndi kochepa, ndipo mtengo wake wathandizanso.

Sabata yatha, Xinyue ndi Jiahong motsatizana adakweza magwiridwe antchito oipa, kuphatikiza kuyambiranso kwa chipangizo cha gawo loyamba cha Wanhua, mpaka pa Seputembala 15, kuchuluka kwa kugwiritsa ntchito mphamvu zamafakitale kudakwera kufika pa 71.50%, kuwonjezeka kwa 5.79 peresenti poyerekeza ndi chiyambi cha mweziwo, kukula kwa kupanga tsiku ndi tsiku kwa matani 0.1 miliyoni, pomwe East China ili ndi ndalama zaku US ndi Zhejiang zombo zonyamula mafuta zomwe zikupereka kudoko, malo am'deralo ali ndi chowonjezera china.

Mu ndondomeko yotsatirayi, palibe dongosolo losinthasintha la zipangizo zambiri zomwe zili pamalopo, ndipo Jincheng Petrochemical anayamba kugulitsa hydrogen peroxide, koma chipangizo chake cha HPPO cha 300,000 / chaka sichikuyembekezeka kuyambiranso, pitirizani kulabadira kuti chakudya chonsecho chikuyembekezeka kukhala chokhazikika tsiku lisanafike.

Chachiwiri, zipangizo zopangira zinthu zili pamwambazi zikupitirira kukwera kwambiri

Kuchokera pamalingaliro a mtengo, sabata yatha, zinthu zazikulu zopangira propylene ndi chlorine yamadzimadzi mu njira ya chlorohydrin zakwera kwambiri, zomwe zafika pamlingo wapamwamba kwambiri chaka chino, ngakhale mtengo wa cyclopropylene nawonso wakwera pang'ono, koma kuchuluka kwa kukula sikuli mwachangu ngati mtengo, ndipo kuchuluka kwa kutayika kukukulitsidwa kwambiri poyerekeza ndi chiyambi cha mwezi uno, pamsika wokwerawu, zotsatira zabwino pamtengo ndizolimba, komanso njira ya HPPO, chifukwa mtengo wa zinthu wamba zopangira propylene wakwera. Hydrogen peroxide imawerengedwa malinga ndi mtengo wa chipangizo chongopeka, ndipo kusiyana kwa mtengo pakati pa njira ziwirizi kwachepetsedwa, koma mtengo wa hydrogen peroxide ukupitirira kukwera kwambiri, ndipo ndikofunikira kulabadira ngati zimakhudza njira zina za HPPO kuti musinthe katundu wa chipangizo chawo cha cyclopropyl ndikugulitsa hydrogen peroxide kunja.

Sabata ino, propylene ndi chlorine yamadzimadzi zikuyembekezeka kukhazikika pamlingo wapamwamba, ndipo zikuyembekezeka kuti pansi pa msika wobwezeretsanso pang'ono asanapite ku tchuthi, pali chithandizo china pamsika wa cycloC.

Chachitatu, mbali yofunikira ya kusamala pang'ono pamtengo wokwera wodikira ndikuwona

Ponena za kufunikira kwa zinthu zomwe zikubwera, magwiridwe antchito a maoda atsopano a polyether kumapeto kwa nyengo ya "golide nine" akadali okhutiritsa koma osati malinga ndi zomwe amayembekezera, poyerekeza ndi msika mu Julayi-Ogasiti, palibe kusintha kwakukulu komwe kwachitika, pambuyo poti CIC yatsika sabata yatha, kuwonjezeka kwatsopano kwa zinthu zomwe zikubwera kumakhala kochepa, makamaka kutengera kupereka maoda koyambirira, ndipo pambuyo poti CIC yakwera mitengo, kagulidwe kake nthawi zambiri kamachepa. Makampani opanga propylene glycol nthawi zambiri amakhala opindulitsa, ndipo chipangizocho chimasinthasintha kwambiri, ndipo zotsatira zake zimakhala zochepa.

Mu zotsatira zake, patsala milungu iwiri kuchokera pa tchuthi cha 11, pamsika wokwerawu, makasitomala ena ali ndi zinthu zochepa, ndipo pakadalibe kufunikira kochepa sabata ino, ndipo kumapeto kwa mweziwu nthawi ya tchuthi ikuyandikira, ndipo msika ukuyembekezeka kukhala patchuthi chimodzi ndi chimodzi.

Chachinayi, kukwera kungachedwetse chikondwerero chokhazikika kapena mtunda wopapatiza

Pomaliza (kwa kanthawi kochepa): Sabata yatha, mtengo wokwera wamsika unakwera kufika pachimake chatsopano mu theka lachiwiri la chaka, ndipo posachedwapa, kusagwirizanaku kukuyembekezeka kubwerera kukhazikika, sabata ino, pakadalibe kufunikira kochepa kwa masheya a polyether kumapeto, CIC ikuyembekezeka kukhala kusagwirizana, kumapeto kwa mwezi, magulu akuchirikiza kufooka, kapena pali kuchepa pang'ono kwa ziyembekezo.

Pomaliza (kwa nthawi yapakati ndi yayitali): Mu Okutobala, tiyenera kusamala ndi kusinthasintha kwa zida zosiyanasiyana panthawi ya tchuthi, Tianjin Bohua akuyembekezeka kuyambiranso pambuyo pa tchuthi, Shandong Jinling ikhoza kukhala ndi ziyembekezo zosamalira, kubwerera kumtunda wopapatiza katunduyo atakonzedwa, ndipo kukonza kwa Shell mu theka lachiwiri la chaka, samalani ndi zomwe zikuchitika.

Chenjezo la zoopsa: kusatsimikizika kwa nthawi yowonjezera ya chipangizocho; Ngati mtengo ukukwera pambuyo poti bizinesi yayamba; Kufunika kwa malo enieni ogwiritsira ntchito.
