Mtsogoleli: Kuyambira Seputembala, msika wapakhomo wa propylene oxide wawonetsa kukwera pang'onopang'ono, kumayambiriro kwa mweziwo, maphwando onse pamsika ali ndi chiyembekezo cha "golide naini" pachimake, msika ukupitilira kukwera ndipo kukwera, koma kunakwera mpaka 9550-9670 yuan/tani (Shandong spot exchange exchange fakitale), msika wasintha kwambiri, mpaka kumlingo wakutiwakuti, udagunda chidaliro chamakampaniwo, kumapeto kwa sabata yatha pambuyo pakutsika koyenera kwa cyC, ndi mtengo wa kukoka koonekeratu, Msika mwamsanga unasiya kugwa ndikulowetsa msika wina wopita kumtunda, kuyambira pa September 15, mpaka 9650-9750 yuan/tani, kufika pamtunda wachiwiri wa chaka, ndipo kukula kwakukulu kunachepa.

Choyamba, kuchuluka kwa mphamvu zogwiritsira ntchito mphamvu zothandizira kukuwonetsa njira yochira

Chakumapeto kwa September, mphamvu magwiritsidwe mlingo wa zoweta propylene okusayidi msika wakhala anakhalabe pa mlingo otsika pafupifupi 60% -65%, ndi zipangizo zambiri monga Jincheng Petrochemical, Taixing Yida, Wanhua Phase I, Tianjin Bohua ndi. m'malo oimika magalimoto, komanso kukonza kwakanthawi kochepa komanso kuchepetsa zida zazikulu monga Xinyue ndi Jiahong, ndi zina zambiri, msika umakhala wocheperako, ndipo mtengo wake wathandiziranso.

Mlungu watha, Xinyue ndi Jiahong motsatizana anadzutsa ntchito zoipa, pamodzi ndi kuyambiransoko kwa Wanhua gawo I chipangizo, kuti September 15, makampani mphamvu magwiritsidwe ntchito kuchuluka kwa 71.50%, kuwonjezeka kwa 5.79 peresenti poyerekeza ndi chiyambi cha mwezi, Kukula kwa tsiku ndi tsiku kwa matani 0.1 miliyoni, pomwe East China ili ndi dola yaku US ndi Zhejiang petrochemical ship katundu wonyamula katundu ku doko, malo amderalo ali ndi chowonjezera china.

Potsatira, palibe dongosolo la kusintha kwa zipangizo zambiri zomwe zili pamalopo, ndipo Jincheng Petrochemical anayamba kugulitsa hydrogen peroxide, koma chipangizo chake cha 300,000 / chaka cha HPPO sichinayembekezere kuyambiranso, pitirizani kumvetsera zonse zomwe zilipo. ikuyembekezeka kukhala yokhazikika tchuthi chisanachitike.

Chachiwiri, zipangizo ndi mkulu anapitiriza kukwera kwambiri

Kuchokera pamalingaliro amtengo, sabata yatha, zida zazikulu zopangira propylene ndi chlorine yamadzimadzi mu njira ya chlorohydrin zawonjezeka kwambiri, zomwe zafika pamlingo wapamwamba kwambiri mchaka, ngakhale mtengo wa cyclopropylene wakweranso pamlingo wina, koma kuchuluka kwa kukula sikofulumira ngati mtengo, ndipo digiri yotayika imakulitsidwanso poyerekeza ndi chiyambi cha mwezi, mumsika uwu wa msika wokwera, zotsatira zabwino pamtengo zimakhala zolimba, ndi ndondomeko ya HPPO, chifukwa mtengo wamba wamba propylene wakwera. Peroxide ya haidrojeni imawerengedwa molingana ndi mtengo wa chipangizocho, ndipo kusiyana kwa mtengo pakati pa njira ziwirizi kumachepetsedwa, koma mtengo wa hydrogen peroxide ukupitiriza kukwera kwambiri, ndipo m'pofunika kumvetsera ngati zimakhudza njira zina za HPPO kusintha katundu. a chipangizo chawo cha cyclopropyl ndikugulitsa hydrogen peroxide kunja.

Sabata ino, propylene ndi madzi chlorine akuyembekezeka kuphatikizika kwambiri, ndipo akuyembekezeka kuti pansi pa msika wobwezeretsanso pang'ono patchuthi, pali chithandizo china pamsika wa cycloC.

Chachitatu, mbali yofunikira ya mtengo wocheperako wodikirira ndikuwona wosamala

Pankhani ya kutsika kwa madzi, ntchito ya polyether mapeto oda latsopano mu "golide zisanu ndi zinayi" pachimake nyengo akadali wokhutiritsa koma osati mpaka ziyembekezo, poyerekeza ndi msika mu July-August, palibe kusintha kwakukulu, ataona CIC pansi. sabata yatha, kutsika kwatsopano kumodzi kowonjezereka kumachepa mosalekeza, makamaka potengera kutumizidwa kwa malamulo oyambirira, ndipo mutayang'ana mitengo yamtengo wapatali ya CIC, nyimbo yogula nthawi zambiri imachepetsedwa. Makampani a propylene glycol nthawi zambiri amakhala opindulitsa, ndipo chipangizocho chimasinthasintha kwambiri, ndipo zotsatira zake zimakhala zochepa.

Potsatira, patsala milungu iwiri kuchokera ku tchuthi cha 11, mumsika uwu wa msika wopita patsogolo, makasitomala ena akhala akusungidwa pang'ono, ndipo pakufunikabe pang'ono sabata ino, ndipo mapeto a mwezi akuyandikira. nthawi yatchuthi, ndipo msika ukuyembekezeka kukhala patchuthi chimodzi ndi chimodzi.

Chachinayi, kukwerako kungachedwetse patsogolo chikondwerero chokhazikika kapena chochepa

Kutsiliza (nthawi yochepa) : Mlungu watha, mtengo wamsika wam'mwamba unakwera kumalo atsopano mu theka lachiwiri la chaka, ndipo posachedwapa, kuyimitsidwa kukuyembekezeka kubwereranso ku bata, sabata ino, akadali ndi ndalama zochepa. kufunikira kwa mapeto a polyether, CIC ikuyembekezeka kuima, kumapeto kwa mweziwo, maphwando amathandizira kufooketsa, kapena pali kuchepa pang'ono kwa ziyembekezo.

Kutsiliza (apakatikati ndi nthawi yaitali) : Mu October, tiyenera kulabadira kusinthasintha kwa zipangizo zosiyanasiyana pa tchuthi, Tianjin Bohua akuyembekezeka kuyambiranso pambuyo holide, Shandong Jinling angakhale ndi ziyembekezo yokonza, kubwerera ku yopapatiza osiyanasiyana pambuyo katundu. zakonzedwa, ndi kukonza Shell mu theka lachiwiri la chaka, tcherani khutu ku zochitika zenizeni.

Chenjezo lachiwopsezo: kusatsimikizika kwa nthawi yowonjezereka ya chipangizocho; Ngati kukakamizidwa kwa mtengo pambuyo pa chidwi chabizinesi kuyamba; Fufuzani malo enieni ogwiritsira ntchito.
