Kuyambira Novembala, msika wonse wapakhomo wa epoxy propane wawonetsa kutsika kofooka, ndipo kuchuluka kwamitengo kwatsika kwambiri. Sabata ino, msika udagwetsedwa ndi mbali ya mtengo, koma panalibenso mphamvu zodziwikiratu zotsogola, kupitiliza kukhazikika pamsika. Pambali yopereka, pali kusinthasintha kwapayekha ndi kuchepetsedwa, ndipo msika ndi wokulirapo. Mu Novembala, panalibe msika wofunikira kwambiri, ndipo kusinthasintha kwamitengo kunali kocheperako. Zotumiza m'mafakitale mkati mwa mweziwo zinali zathyathyathya, ndipo zosungiramo nthawi zambiri zinali zapakati, zomwe zikuwonetsa kuchulukirachulukira.

Kuchokera pakuwona mbali yoperekera, kupezeka kwapanyumba kwa epoxy propane kumakhala pamlingo wocheperako mkati mwa chaka. Kuyambira pa November 10, kupanga tsiku ndi tsiku kunali matani 12000, ndi mphamvu yogwiritsira ntchito mphamvu ya 65.27%. Pakadali pano, kuyimitsidwa kwa Yida ndi Jincheng pamalowa sikunatsegulidwe, ndipo gawo lachiwiri la CNOOC Shell lakhala likukonzedwa mosalekeza kwa mwezi wathunthu. Shandong Jinling akuyima kuti akonzeko kamodzi pa Novembara 1, ndipo zinthu zina zikugulitsidwa. Kuphatikiza apo, onse a Xinyue ndi a Huatai adakumana ndi kusinthasintha kwakanthawi kochepa ndikuyambiranso masiku oyambirira. M'kati mwa mweziwo, katundu wochokera ku fakitale yopangira zinthu amakhala pafupifupi, ndipo zinthu zambiri zimakhala zapakati, ndipo nthawi zina zimakhala zopanikizika. Ndi kuwonjezera kwa ndalama za East China US dollar, zinthu zonse ndizochuluka.

Malinga ndi mtengo, zida zazikulu za propylene ndi chlorine yamadzimadzi zawonetsa kukwera m'masiku aposachedwa, makamaka mtengo wa propylene ku Shandong. Chifukwa chokhudzidwa ndi kuchepa kwa zinthu komanso kufunika kosalekeza, idakwera kwambiri kumayambiriro kwa sabata ino, ndikuwonjezeka tsiku lililonse kopitilira 200 yuan/ton. Njira ya epoxy propane chlorohydrin pang'onopang'ono idawonetsa kutayika mkati mwa sabata, kenako idasiya kugwa ndikukhazikika. Pamsika uwu, mbali yamtengo wapatali idathandizidwa bwino ndi msika wa epoxy propane, koma kuchepa kutayima, mbali yamtengo wapatali idawonetsabe kukwera. Chifukwa cha mayankho ochepa kuchokera kumbali yofunidwa, msika wa epoxy propane sunapitirirebe. Pakali pano, mitengo ya propylene ndi liquid chlorine ndi yokwera kwambiri, ndipo mitengo yamafuta amafuta yatsika kwambiri komanso kutsika mtengo kwa propylene ndi liquid chlorine. Zingakhale zovuta kusunga mitengo yapamwamba yamakono m'tsogolomu, ndipo pali chiyembekezo cha kuchepa kwa zinthu.

Kuchokera kumbali yofunikira, nyengo yapamwamba ya "Golden Nine Silver Ten" yachita bwino kwambiri, pomwe Novembala nthawi zambiri imakhala nyengo yachikhalidwe. Madongosolo a polyether akumunsi ndi avareji, ndipo tikuwona kusinthasintha kwamitengo pamsika woteteza zachilengedwe wocheperako. Panthawi imodzimodziyo, popanda zikhazikitso zomveka bwino, malingaliro ogula nthawi zonse amakhala osamala komanso okonda zofuna. Makampani ena akumunsi monga propylene glycol ndi flame retardants nthawi zambiri amakumana ndi nthawi yokonzekera chifukwa cha mpikisano waukulu komanso kusapindula bwino. Kutsika kwaposachedwa kwakugwiritsa ntchito mphamvu zopangira kumapangitsa kuti zikhale zovuta kupereka chithandizo chothandiza pakuteteza chilengedwe. Kumapeto kwa chaka, mabizinesi anali ndi malingaliro ochulukirapo pakuvomera maoda, ndipo anali ochepa pamalingaliro awo oyambira masheya chifukwa cha msika wochuluka mdera lachitatu. Ponseponse, mayankho amtundu wotsatira wa band ndi ochepa.

Kuyang'ana m'tsogolo momwe msika ukuyendera, tikuyembekezeka kuti msika wa epoxy propane ukhalabe wosinthasintha ndikuphatikizana pakati pa 8900 mpaka 9300 yuan/ton pakutha kwa chaka. Zotsatira za kusinthasintha kwa munthu payekha komanso kusagwirizana pa gawo loperekera pamsika ndizochepa, ndipo ngakhale mbali yamtengo wapatali imakhala ndi mphamvu yokweza mphamvu, zimakhala zovuta kuyendetsa mmwamba. Ndemanga zochokera kumbali yofunikira ndizochepa, ndipo kumapeto kwa chaka, mabizinesi amakhala ndi malingaliro ochulukirapo pakulandila maoda, zomwe zimapangitsa kuti pakhale mapulani osungitsa pasadakhale. Chifukwa chake, zikuyembekezeka kuti msika ukhalabe wokhazikika pakanthawi kochepa. Komabe, ndikofunikira kuyang'anitsitsa ngati pali chizolowezi chotseka kwakanthawi ndikuchepetsa koyipa kwa magawo ena opanga mokakamizidwa ndi mtengo, komanso kulabadira kupita patsogolo kwa Ruiheng New Materials (Zhonghua Yangnong).
