Kuyambira mwezi wa February, msika wapakhomo wa propylene oxide wawonetsa kukwera kosasunthika, ndipo pansi pa mgwirizano wa mbali ya mtengo, mbali yoperekera ndi kufunikira ndi zinthu zina zabwino, msika wa propylene oxide wawonetsa kukwera kwa mzere kuyambira kumapeto kwa February.Pofika pa Marichi 3, mtengo wotumizira wa propylene oxide ku Shandong wakwera mpaka 10900-11000 yuan/ton, kukwera kwatsopano kuyambira Juni 2022, 1100 yuan/ton kapena 11% kuposa mtengo wa February 23.
Kuchokera pamalingaliro operekera, Ningbo Zhenhai Refining ndi Chemical Plant Phase I adatsekedwa kuti akonzere pa February 24. Nthawi yoyerekeza inali pafupifupi mwezi umodzi ndi theka.Kuchita kwazinthu zamsika pamsika wakumwera kunali kolimba, pomwe kusintha kwa zida zamabizinesi akumpoto sikunali kwakukulu.Mabizinesi ena anali ndi magwiridwe antchito oyipa, ndipo kuchepa kwa mabizinesi kunali ndi malonda ochepa.Panali chithandizo chabwino pamsika wogulitsa;Kuonjezera apo, kupanga mphamvu zatsopano sizomwe zimayembekezeredwa.Tianjin Petrochemical Plant idatsekedwa mkati mwa February kuti athetse zolakwika.Satellite Petrochemical idakhalabe ndi ntchito yotsika kwambiri.Ngakhale kuti katundu woyenerera anapangidwa, sanatumizidwe kunja kwaunyinji.Zomera za Shandong Qixiang ndi Jiangsu Yida sizinayambitsenso kupanga.Jincheng Petrochemical ikuyembekezeka kupangidwa mu Marichi.
Pakufunidwa, pambuyo pa tchuthi cha Chikondwerero cha Spring ku China, kubwezeredwa kwazinthu zonse zapakhomo ndi zogulitsa kunja m'mafakitale osiyanasiyana apanyumba kunali kochepa kuposa momwe amayembekezera.Komabe, chifukwa cha kukwera mtengo kwa propylene oxide, mtengo wa polyether wakumunsi unakwera pang'onopang'ono, msika unali wabwino pogula ndi kusunga, ndipo mtengo wa propylene oxide unakhalabe wokwera.Mothandizidwa ndi malingaliro ogula ndikusagula, mabizinesi aposachedwa a polyether adatsata mochulukirachulukira, ndikupangitsa msika wa propylene oxide kuti upitilize kuyenda bwino.
Pankhani ya mtengo, pankhani ya propylene, kukakamiza kwaposachedwa kwamakampani opanga ma propylene kwatsika ndipo kupereka kwawonjezeka.Motsogozedwa ndi kubwezeretsedwa kwa tsogolo la polypropylene, msika wonse wamalonda wamsika wayenda bwino, ndipo malo ogulitsa akwera.Kuyambira pa March 3, mtengo wamtengo wapatali wa propylene ku Province la Shandong wakhala 7390-7500 yuan/tani;Pankhani ya madzi a klorini, chifukwa cha kusintha kwa zida zogwiritsira ntchito chlorine kumtunda, kuchuluka kwa malonda a klorini wamadzimadzi kwatsika, kuchirikiza mtengowo kuti ukwerenso mpaka 400 yuan/tani.Mothandizidwa ndi kukwera kwa mtengo wa chlorine wamadzimadzi, kuyambira pa Marichi 3, mtengo wa PO wa njira ya chlorohydrin udakwera pafupifupi 4% poyerekeza ndi February 23.
Pankhani ya phindu, kuyambira pa Marichi 3, phindu la PO la njira ya chlorohydrin linali pafupifupi 1604 yuan/ton, kukwera 91% kuyambira pa February 23.
M'tsogolomu, msika wa propylene kumapeto kwa zinthu zopangira ukhoza kupitiriza kuwonjezeka pang'ono, msika wamadzimadzi wa klorini ukhoza kukhalabe ndi ntchito yolimba, ndipo kuthandizira kumapeto kwa zinthu zopangira kumawonekerabe;Woperekayo akadali wolimba, komabe m'pofunika kudikira ndikuwona momwe ntchito yatsopano ikugwiritsidwira ntchito;Kumbali yofunikira, mu nyengo yofunikira kwambiri mu Marichi, kufunikira kwa msika wa polyether kumatha kukhalabe pang'onopang'ono kuchira, koma chifukwa cha mtengo waposachedwa wa polyether wokakamizika, malingaliro ogula atha kukhala akuchepera;Pazonse, pali chithandizo chothandizira pakanthawi kochepa.Zikuyembekezeka kuti msika wa propylene oxide ukhalabe wokhazikika, wapakatikati komanso wamphamvu pakanthawi kochepa, ndipo tidikirira malamulo otsika a polyether.
