Isingeniso: “Igolide nesiliva eziyisishiyagalolunye neshumi” ngemuva kwemikhiqizo yochungechunge lwemboni ye-propylene oxide kaNovemba ingena esikhathini esingesihle, uhlangothi lokuhlinzeka lusenezinye izindlela zokulungisa kanye nokuguquguquka okungekuhle, kodwa ukusebenza kohlangothi lokufunwa kuyabanda, ngemuva kokuthi ukudluliselwa okuphansi kuvinjiwe, ukuphela kwezinto zokusetshenziswa kwemakethe ye-cyclic kucindezele kancane kancane, ukuqina kwemakethe kubuthakathaka, amanani efektri yeShandong spot kule mpelasonto aphinde ehla afinyelela ku-9000 yuan/ton mark; Ngemuva kokufinyelela le ntengo, ukuthengwa kokulandelela okulinganiselwe okuphansi kulindeleke ukuthi kwehle okwesikhashana.

Okokuqala, ukunakwa okuguquguqukayo kwedivayisi ye-HPPO ohlangothini lokuhlinzeka

Ukunikezwa kunciphise izinga lokusetshenziswa kwamandla amanje ukuze kugcinwe u-65% uzulazula, indawo yokupaka i-Yida, i-Jincheng ayizange ivuleke, isimo sokugcinwa okuqhubekayo kwesigaba sesi-2 se-China Sea Shell, i-North Jinling, i-Huatai inokulungiswa kokupaka, kodwa phakathi nesikhathi sokupaka kukhona impahla eningi ethengisiwe, ayizange ithinte ukunikezwa komphumela wokunciphisa okulinganiselwe, okuhambisana nokuthunyelwa kwangaphambi kwesikhathi akukuhle, umhlinzeki esitshalweni sokukhiqiza ungaphezu kwengcindezi ethile, Muva nje, amanani ehlile kancane.

Ukulandelela, ukuqala kabusha kweJinling nokubuyiselwa kule mpelasonto, kulindeleke ukuthi okunye ukuncipha, ukunikezwa kwemakethe ye-propylene oxide yasekhaya kuningi, isethi eyodwa noma umthelela wokuncipha kwamandla amancane unqunyelwe, kodwa amasethi amabili amadivayisi amakhulu e-HPPO, ingcindezi yezindleko, ehlanganiswe nezinto zokusetshenziswa eziphezulu kanye nomthelela wePanama Canal, ikhathazekile ngokuthi izoyeka yini ngoDisemba noma ibe nomthelela othile emakethe.

Okwesibili, uhlangothi lwezindleko luhlala luqinile. Inqubo ngayinye ingaphansi kwengcindezi

Ngokombono wezindleko, intengo ye-propylene yezinto zokusetshenziswa isanda kushintshashintsha ibe yi-yuan engu-7,000/ton, yize intengo ye-chlorine ewuketshezi yehle kusukela ekuqaleni kwenyanga, isakwazi ukugcina i-yuan engu-300-400/ton yentengo enhle yokusebenza, izindleko zizonke zihlale zinhle, kodwa yize inqubo yamanje isacindezelekile, ukuphela kwezinto zokusetshenziswa eziqinile kubuthakathaka ukukhuthaza ukwesekwa kwemakethe okungaphansi kwe-propylene yangaphambilini, i-chlorine ewuketshezi iqine isigaba sokukhuphuka.

Ukulandelela, intengo ye-propylene yehle ngempelasonto, i-chlorine ewuketshezi ibukeka izinzile okwesikhashana, ngemuva kokuba intengo yamanje ye-cyclopropylene ifinyelele uphawu lwama-yuan angu-9000/ton, izindleko ziphansi, ukuthengwa okulinganiselwe kanye nokulandelela, kodwa ukuthi ingaqhubeka yini ilinde impendulo yama-oda esiphetho, kuyilapho inaka intengo ye-propylene yezindleko zenqubo ye-HPPO.

Okwesithathu, uhlangothi lwesidingo lokuthenga okubandayo emakethe ludinga nje ukulandelwa

Ngokuphathelene nesidingo esingezansi, umkhuhlane jikelele ngoNovemba uqhubekele emakethe, imboni ye-polyether uma iqhathaniswa negolide, ama-oda amasha ayisishiyagalolunye esiliva ayishumi abuthakathaka kakhulu, kuleli sonto imakethe eguquliwe, izindleko zokugcina ze-cyC zilinganiselwe, kodwa impendulo yamakhasimende ayisanele, imboni ye-polyether nayo ingaphansi kwesistimu, amanye amafektri athengisa imikhiqizo ephezulu ukuze athenge i-cyC kuphela ukuze alondoloze ukukhiqizwa okuvamile okudingayo, kunzima ukuba nevolumu ephumelelayo. Ngokombono walo lonke imboni, ngaphansi kwesimo samanje senzuzo embi kanye nokulahlekelwa yi-propylene glycol, indawo yokupaka kanye nokugcinwa kwezitshalo eziningi, ukuthenga esitshalweni sokukhiqiza kuncane kakhulu, futhi isigqi sihamba kancane futhi kunzima ukusekela i-cyclopropylene.

Uhlangothi lwesidingo sempendulo yesikhathi esingaphandle kwesizini lunqunyelwe, ukuguquguquka kwentengo yemakethe ye-CIC yokulinda nokubona kunciphile, indawo yokuthenga isakazekile, kodwa ingozi yokufinyelela uphawu lwama-yuan angu-9000/ton iphansi kakhulu, futhi kukhona ukulandelwa okulinganiselwe.

Okwesine, ukuphela kokuhlanganiswa kwentengo okufushane kwesizini

Isiphetho (sesikhathi esifushane): Ngemva kokuba imakethe isibuyele emkhawulweni, uhlangothi lwesidingo oluzayo luzolandela ngokuthenga okwengeziwe ngempelasonto, kodwa phakathi naleso sikhathi, ikhasimende lokugcina kunzima ukuthola impendulo ecacile, futhi imakethe idinga ukulinda ama-oda amasha azayo ngoMsombuluko ngemuva kokwehla kwesikhashana.

Isiphetho (esiphakathi nesikhathi eside): Kusukela ngoNovemba kuya kuDisemba ekupheleni konyaka, ukunikezwa kwemakethe kanye nesidingo kulindeleke ukuthi kuqhubeke nokushintshashintsha ebangeni elincane, uhlangothi lwezindleko noma ngesikhathi esifanele lusekela imakethe ukuqinisekisa ukuthi intengo ye-cyC igcinwa ebangeni eliphakathi kuka-8900-9300 yuan/ton, kodwa kubalulekile ukunaka ukuthi ngabe kukhona yini ukuguquguquka okungekuhle kokuma nokuwa kwamadivayisi amakhulu ngaphansi kwengcindezi yezindleko. Futhi unake inqubekela phambili yokukhiqizwa kwamadivayisi amasha njengeRuiheng New Materials (Sinochem Yangnong), Wanhua Chemical, Lihua Yiweiyuan kanye neSinochem Tianchen.

Isexwayiso sengozi: ukungaqiniseki kwesikhathi esiqhubekayo sendawo yedivayisi; Uma izindleko zicindezela ngemva kwesifiso sebhizinisi sokuqala; Isidingo sokufika kwangempela kokusetshenziswa.
