Inkokeli: Ukusukela ngoSeptemba, imakethi yepropylene oxide yasekhaya iyonke ibonakalise ukuqhubekeka kokunyuka, ekuqaleni kwenyanga, onke amaqela kwimakethi enethemba malunga nexesha le-"gold nine" eliphakamileyo, imakethi iqhubekile nokunyuka, kodwa inyuke yaya kwi-9550-9670 yuan/ton (iShandong spot exchange factory), imakethi ijike yaqina, ukuya kwinqanaba elithile, yabetha ukuzithemba kweshishini, ngempelaveki ephelileyo emva kokwehla okufanelekileyo kwi-cyC, ngexabiso lokutsala okucacileyo, imakethi yayeka ukuwa ngokukhawuleza yaza yangenisa olunye ujikelezo lwemakethi ephezulu, ukusukela ngoSeptemba 15, ukuya kwi-9650-9750 yuan/ton, yafikelela kwinqanaba eliphezulu kwisiqingatha sesibini sonyaka, kwaye ukukhula ngokubanzi kwehla.

Okokuqala, izinga lokusetyenziswa komthamo kwicala lobonelelo libonakalise umkhwa wokubuyela kwimeko yesiqhelo

Phakathi ekuqaleni kukaSeptemba, izinga lokusetyenziswa kwamandla kwimarike yasekhaya yepropylene oxide lihlala ligcinwe kwinqanaba eliphantsi elimalunga nama-60%-65%, kwaye izixhobo ezininzi ezifana neJincheng Petrochemical, iTaixing Yida, iWanhua Phase I, iTianjin Bohua zikwimeko yokupaka, kunye nokugcinwa kwexesha elifutshane kunye nokunciphisa izixhobo ezinkulu ezifana neXinyue kunye neJiahong, njl.njl., ukunikezelwa kwemarike kunqongophele, kwaye ixabiso likwadlale inkxaso ethile.

Kwiveki ephelileyo, iXinyue kunye neJiahong ziqhubele phambili ngokuphakamisa ukusebenza okungalunganga, kunye nokuqaliswa kwakhona kwesixhobo se-Wanhua phase I, ukuya kuthi ga nge-15 kaSeptemba, izinga lokusetyenziswa kwamandla kushishino linyuke laya kwi-71.50%, ukunyuka kweepesenti ezingama-5.79 xa kuthelekiswa nokuqala kwenyanga, ukukhula kwemveliso yemihla ngemihla kwe-0.1 yezigidi zeetoni, ngelixa iMpuma China inedola yaseMelika kunye neZhejiang petrochemical ship cargo provider echwebeni, indawo yasekuhlaleni inesongezelelo esithile.

Kwinkqubo elandelayo, akukho sicwangciso sokuguquguquka kwezixhobo ezininzi ezikwindawo, kwaye iJincheng Petrochemical yaqala ukuthengisa i-hydrogen peroxide, kodwa isixhobo sayo se-HPPO esingama-300,000 / ngonyaka asikalindelwanga ukuba siqalise kwakhona, qhubeka unikele ingqalelo kubonelelo olupheleleyo kulindeleke ukuba luzinze ngaphambi kweholide.

Okwesibini, izinto ezikrwada ziphezulu ziyaqhubeka nokunyuka kakhulu

Ngokwembono yeendleko, kwiveki ephelileyo, izinto eziphambili zepropylene kunye ne-chlorine engamanzi kwindlela ye-chlorohydrin zinyuke kakhulu, nto leyo efikelele kwinqanaba eliphezulu kunyaka, nangona ixabiso le-cyclopropylene nalo linyukile ukuya kwinqanaba elithile, kodwa izinga lokukhula alikhawulezi njengexabiso, kwaye inqanaba lokulahleka landiswa ngakumbi xa kuthelekiswa nokuqala kwenyanga, kule ngqungquthela yemarike ephezulu, isiphumo esihle kwixabiso sinamandla, kunye nenkqubo ye-HPPO, kuba ixabiso le-propylene yezinto eziqhelekileyo linyukile. I-hydrogen peroxide ibalwa ngokwexabiso lesixhobo sethiyori, kwaye umahluko weendleko phakathi kwezi nkqubo zimbini unciphile, kodwa ixabiso le-hydrogen peroxide liyaqhubeka linyuka kakhulu, kwaye kuyimfuneko ukuqwalasela ukuba ingaba ichaphazela na ezinye iinkqubo ze-HPPO ukulungisa umthwalo wesixhobo sabo se-cyclopropyl kwaye sithengise i-hydrogen peroxide kwamanye amazwe.

Kule veki, kulindeleke ukuba ipropylene kunye ne-chlorine engamanzi zihlangane kwinqanaba eliphezulu, kwaye kulindeleke ukuba phantsi kwemarike yokuzalisa inxalenye ngaphambi kweeholide, kusekho inkxaso ethile kwimarike ye-cycloC.

Okwesithathu, icala lemfuno yexabiso eliphezulu lokulinda nokubona elikhawulezileyo liphantsi kakhulu

Ngokuphathelele imfuno esezantsi, ukusebenza kwee-odolo ezintsha ze-polyether end kwixesha le-"gold nine" peak season kusanelisa kodwa akufikeleli kulindelo, xa kuthelekiswa nemarike ngoJulayi-Agasti, akukho phuculo lubonakalayo, emva kokubukela i-CIC isezantsi kwiveki ephelileyo, ukunyuka okutsha okuncinci kunqunyelwe ekuqhubekeni, ikakhulu kusekelwe ekunikezelweni kwee-odolo zakuqala, kwaye emva kokubukela amaxabiso aphezulu e-CIC, isigqi sokuthenga ngokubanzi siyehla. Ishishini le-propylene glycol ngokubanzi linenzuzo, kwaye isixhobo siyatshintshatshintsha ngakumbi, kwaye impembelelo incinci.

Kwingxelo elandelayo, kusekho iiveki ezimbini ukusuka kwiholide ye-11, kulo mjikelo wemarike enyukayo, abanye abathengi banezinto ezifunekayo, kwaye kusekho inani elincinci leemfuno kule veki, kwaye ukuphela kwenyanga kusondela ixesha leeholide, kwaye kulindeleke ukuba imakethi ibe kwiiholide enye emva kwenye.

Okwesine, ukunyuka kunokucotha ngaphambi komnyhadala wokuzinzisa okanye umgama omxinwa

Isiphelo (sexesha elifutshane): Kwiveki ephelileyo, ixabiso lemarike elinyukileyo lenyuke laya kwinqanaba eliphezulu kwisiqingatha sesibini sonyaka, kwaye kutshanje, imeko ilindeleke ukuba ibuyele kuzinzo, kule veki, kusekho inani elincinci lemfuno yesitokhwe se-polyether end, i-CIC kulindeleke ukuba imeko ingabi yimpumelelo, ngasekupheleni kwenyanga, amaqela axhasa ubuthathaka, okanye kukho ukwehla okuncinci kolindelo.

Isiphelo (sexesha eliphakathi nelide): Ngo-Okthobha, kufuneka siqwalasele ukuguquguquka kwezixhobo ezahlukeneyo ngexesha leeholide, kulindeleke ukuba iTianjin Bohua iqalise kwakhona emva kweholide, iShandong Jinling isenokuba nolindelo lokugcinwa, ibuyele kuluhlu oluncinci emva kokuba isitokhwe silungisiwe, kwaye ukugcinwa kweShell kwisiqingatha sesibini sonyaka, kuthathelwe ingqalelo uphuhliso oluthile.

Isilumkiso somngcipheko: ukungaqiniseki kwexesha elinyukayo lomphezulu wesixhobo; Ukuba uxinzelelo lweendleko emva kokuba ishishini linomdla wokuqalisa; Imfuno ecaleni kokusetyenziswa kokwenyani.
