Ukuhola: Kusukela ngoSepthemba, imakethe yasekhaya ye-propylene oxide iyonke ibonise ukuthambekela okuqhubekayo kokukhuphuka, ekuqaleni kwenyanga, bonke abathintekayo emakethe benethemba ngesizini ye-"gold nine" ende, imakethe iqhubekile nokukhuphuka, kodwa yakhuphuka yaya ku-9550-9670 yuan/ton (ifektri yokushintshanisa indawo yaseShandong), imakethe isiphenduke i-stalemate, ngezinga elithile, yashaya ukuzethemba kwemboni, ngempelasonto edlule ngemuva kokwehla okufanele kwe-cyC, ngezindleko zokudonsa okusobala, Imakethe yayeka ngokushesha ukuwa futhi yangenisa omunye umjikelezo wemakethe ekhuphukayo, kusukela ngoSepthemba 15, yaya ku-9650-9750 yuan/ton, yafinyelela esicongweni engxenyeni yesibili yonyaka, futhi ukukhula okuphelele kwehle.

Okokuqala, izinga lokusetshenziswa kwamandla ohlangothini lokuphakelwa libonise ukuthambekela kokusimama

Maphakathi noSepthemba, izinga lokusetshenziswa kwamandla emakethe yasekhaya ye-propylene oxide lihlale ligcinwa lisezingeni eliphansi elingaba ngu-60%-65%, futhi amadivayisi amaningi afana ne-Jincheng Petrochemical, i-Taixing Yida, i-Wanhua Phase I, i-Tianjin Bohua asesimweni sokupaka, kuhlangene nokugcinwa kwesikhashana kanye nokunciphisa amadivayisi amakhulu omthamo njenge-Xinyue ne-Jiahong, njll., ukunikezwa kwemakethe kunqunyelwe, futhi intengo nayo idlale ukwesekwa okuthile.

Ngesonto eledlule, i-Xinyue ne-Jiahong ziphakamise ukusebenza okungekuhle ngokulandelana, kuhlangene nokuqala kabusha idivayisi yesigaba sokuqala saseWanhua, kuze kube nguSepthemba 15, izinga lokusetshenziswa kwamandla embonini lenyuke laya ku-71.50%, ukwanda kwamaphesenti angu-5.79 uma kuqhathaniswa nokuqala kwenyanga, ukukhula komkhiqizo kwansuku zonke kwamathani ayizigidi ezingu-0.1, kuyilapho i-East China ine-dollar yase-US kanye ne-Zhejiang petrochemical ship cargo plan ethekwini, indawo yasendaweni inesengezo esithile.

Ekulandeleni, akukho uhlelo lokuguquguquka kwamadivayisi amaningi asendaweni, kanti i-Jincheng Petrochemical yaqala ukuthengisa i-hydrogen peroxide, kodwa idivayisi yayo ye-HPPO engu-300,000 / ngonyaka ayikalindeleki ukuthi iqale kabusha, qhubeka unake ukunikezwa okuphelele kulindeleke ukuthi kuzinzile ngaphambi kweholide.

Okwesibili, izinto zokusetshenziswa ziphezulu futhi ziyaqhubeka nokwenyuka kakhulu

Ngokombono wezindleko, ngesonto eledlule, i-propylene yezinto zokusetshenziswa eziyinhloko kanye ne-chlorine ewuketshezi endleleni ye-chlorohydrin kukhuphuke kakhulu, okufinyelele ezingeni eliphakeme kakhulu ngonyaka, yize intengo ye-cyclopropylene nayo ikhuphuke ngezinga elithile, kodwa izinga lokukhula alisheshi njengezindleko, futhi izinga lokulahlekelwa liyanda kakhulu uma kuqhathaniswa nokuqala kwenyanga, kulo mjikelezo wemakethe ephezulu, umphumela omuhle entengo unamandla, kanye nenqubo ye-HPPO, ngoba intengo ye-propylene yezinto zokusetshenziswa ezivamile ikhuphukile. I-hydrogen peroxide ibalwa ngokwezindleko zedivayisi ezisekelwe kumbono, futhi umehluko wezindleko phakathi kwalezi zinqubo ezimbili uncishisiwe, kodwa intengo ye-hydrogen peroxide iyaqhubeka nokwenyuka kakhulu, futhi kuyadingeka ukunaka ukuthi ithinta yini ezinye izinqubo ze-HPPO ukulungisa umthwalo wedivayisi yabo ye-cyclopropyl nokuthengisa i-hydrogen peroxide kwamanye amazwe.

Kuleli sonto, i-propylene kanye ne-chlorine ewuketshezi kulindeleke ukuthi zihlangane ezingeni eliphezulu, futhi kulindeleke ukuthi ngaphansi kwemakethe yokugcwaliswa kabusha kwengxenye ngaphambi kwamaholide, kusekhona ukwesekwa okuthile kwemakethe ye-cycloC.

Okwesithathu, uhlangothi lwesidingo sokuqapha amanani aphezulu okulinda nokubona okukhawulelwe okuqhubekayo

Ngokuphathelene nesidingo esiphansi, ukusebenza kwama-oda amasha e-polyether end esikhathini se-"gold nine" sikhulu kusagculisa kodwa akukafiki kulokho okulindelwe, uma kuqhathaniswa nemakethe ngoJulayi-Agasti, akukho ukuthuthuka okuphawulekayo, ngemuva kokubukela i-CIC inciphile ngesonto eledlule, ukwanda okusha okusha okuphansi kunqunyelwe ekuqhubekeni, ikakhulukazi ngokusekelwe ekulethweni kwama-oda okuqala, futhi ngemuva kokubukela amanani aphezulu e-CIC, isigqi sokuthenga ngokuvamile siyehliswa. Imboni ye-propylene glycol ngokuvamile inenzuzo, futhi idivayisi iyashintshashintsha kakhulu, futhi umthelela unqunyelwe.

Ekulandeleni, kusenezinsuku ezimbili kusukela eholidini le-11, kulo mjikelezo wemakethe ekhuphukayo, amanye amakhasimende agcwele kahle, futhi kusenesidingo esincane kuleli sonto, futhi ukuphela kwenyanga kusondela isikhathi samaholidi, futhi kulindeleke ukuthi imakethe ibe seholidini ngokulandelana.

Okwesine, ukunyuka kungase kwehle ngaphambi komkhosi wokuzinzisa noma ibanga elincane

Isiphetho (isikhathi esifushane): Ngesonto eledlule, intengo yemakethe ekhuphukayo ikhuphuke yaya ezingeni elisha eliphezulu engxenyeni yesibili yonyaka, futhi muva nje, ukungezwani kulindeleke ukuthi kubuyele ekuzinzeni, kuleli sonto, kusenenani elincane lesidingo sesitoko se-polyether end, i-CIC kulindeleke ukuthi ingezwani, ngasekupheleni kwenyanga, amaqembu asekela ubuthakathaka, noma kukhona ukwehla okuncane kokulindelekile.

Isiphetho (esiphakathi nesikhathi eside): Ngo-Okthoba, kufanele sinake ukushintshashintsha kwamadivayisi ahlukahlukene ngesikhathi seholide, iTianjin Bohua kulindeleke ukuthi iqale kabusha ngemva kweholide, iShandong Jinling ingase ibe nokulindela kokugcinwa, ibuyele ebangeni elincane ngemva kokuba isitokwe sesilungisiwe, kanye nokugcinwa kweShell engxenyeni yesibili yonyaka, naka intuthuko ethile.

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