Inkokeli: Ukususela ngoSeptemba, imarike yasekhaya yepropylene oxide iyonke ibonise ukunyuka okuthe gqolo, ekuqaleni kwenyanga, onke amaqela emarike enethemba malunga nexesha lexesha eliphezulu "lesithoba", imarike iqhubekile nokunyuka kwaye ukunyuka, kodwa kwenyuka ukuya kwi-9550-9670 yuan / ton (imboni yokutshintshiselana indawo yaseShandong), imarike iye yajika, kwinqanaba elithile, yabetha ukuzithemba kweshishini, kwimpelaveki edlulileyo emva kokuhla okufanelekileyo kwe-cyC, ngeendleko ze ukutsalwa okucacileyo, Imarike ngokukhawuleza yayeka ukuwa kwaye yangenisa omnye umjikelo wemarike ephezulu, ukususela ngoSeptemba 15, ukuya kwi-9650-9750 yuan / ton, ifikelele kwinqanaba eliphezulu kwisiqingatha sesibini sonyaka, kwaye ukukhula ngokubanzi kwanciphisa.

Okokuqala, umgangatho wokusetyenziswa kwamandla okubonelela ubonise umkhwa wokubuyisela

Phakathi ekuqaleni kukaSeptemba, izinga lokusetyenziswa kwamandla kwimarike yasekhaya yepropylene oxide isoloko igcinwe kwinqanaba eliphantsi malunga ne-60% -65%, kunye nezixhobo ezininzi ezifana neJincheng Petrochemical, Taixing Yida, Wanhua Phase I, Tianjin Bohua. kwindawo yokupaka, kunye nokugcinwa kwexesha elifutshane kunye nokunciphisa izixhobo ezinkulu ezifana ne-Xinyue kunye ne-Jiahong, njl., unikezelo lwemarike lulinganiselwe, kwaye ixabiso liye ladlala inkxaso ethile.

Kwiveki ephelileyo, uXinyue kunye neJiahong ngokulandelelana baphakamisa ukusebenza okungalunganga, kudityaniswa nokuqaliswa kwakhona kwesixhobo se-Wanhua isigaba I, ukuya kwi-15 kaSeptemba, izinga lokusetyenziswa kwamandla kushishino linyuke laya kutsho kuma-71.50%, ukwanda kweepesenti ze-5.79 xa kuthelekiswa nokuqala kwenyanga, ukukhula kwemveliso mihla le 0.1 yezigidi zeetoni, ngelixa i-East China ine-dollar yase-US kunye ne-Zhejiang ye-petrochemical ship cargo cargo offer to the port, the local spot has a supplement.

Ekulandeleni, akukho sicwangciso sokuguquguquka kwezixhobo ezininzi ze-site, kwaye i-Jincheng Petrochemical yaqala ukuthengisa i-hydrogen peroxide, kodwa i-300,000 yayo / ngonyaka isixhobo se-HPPO ayikalindelwanga ngokucacileyo ukuba siqalise kwakhona, siqhubeke sinikele ingqalelo kunikezelo jikelele. kulindeleke ukuba izinzile phambi kweholide.

Okwesibini, izinto eziluhlaza ziphezulu ziqhubeka nokunyuka kakhulu

Ukusuka kwinqanaba leendleko, kwiveki ephelileyo, izinto eziphambili zepropylene kunye neklorine engamanzi kwindlela ye-chlorohydrin ziye zanda kakhulu, eziye zafikelela kwinqanaba eliphezulu kunyaka, nangona ixabiso le-cyclopropylene liye laphakama kwinqanaba elithile, kodwa izinga lokukhula alikho ngokukhawuleza njengeendleko, kwaye idigri yelahleko iyandiswa ngakumbi xa kuthelekiswa nokuqala kwenyanga, kulo mjikelo wemarike ephezulu, isiphumo esihle kwixabiso sinamandla, kunye nenkqubo ye-HPPO, ngenxa yokuba ixabiso yemathiriyeli ekrwada eqhelekileyo inyukile ipropylene. Iperoxide yehidrojeni ibalwa ngokweendleko zesixhobo sethiyori, kwaye umahluko weendleko phakathi kwezi nkqubo zimbini ziyancipha, kodwa ixabiso leperoxide yehydrogen liyaqhubeka nokunyuka ngamandla, kwaye kuyafuneka ukuba kuqwalaselwe ukuba kuchaphazela iinkqubo ezithile zeHPPO ukulungisa umthwalo. kwesixhobo sabo se-cyclopropyl kwaye bathengise i-hydrogen peroxide phesheya.

Kule veki, ipropylene kunye neklorini yolwelo kulindeleke ukuba idityaniswe kwinqanaba eliphezulu, kwaye kulindeleke ukuba phantsi kwemarike yokuzaliswa kwenxalenye yangaphambi kweholide, kusekho inkxaso kwimarike ye-cycloC.

Okwesithathu, icala lemfuno lokunyuka okulinganiselweyo lokulinda kwaye ubone ixabiso eliphezulu lilumkile

Ngokubhekiselele kwimfuno ephantsi, ukusebenza kwe-polyether ekupheleni kwemiyalelo emitsha kwi-"gold nine" i-peak season iseyanelisayo kodwa ingafikeleleki kwizinto ezilindelekileyo, xa kuthelekiswa neemarike ngoJulayi-Agasti, akukho phuculo olubalulekileyo, emva kokubukela i-CIC iphantsi. kwiveki ephelileyo, ezantsi umsinga entsha increment kukhawulelwe ukuqhubeka, ubukhulu becala esekelwe unikezelo imiyalelo kwangethuba, kwaye emva kokubukela CIC amaxabiso aphezulu, isingqisho ukuthenga ngokubanzi ithothelwe. Ushishino lwepropylene glycol lunenzuzo ngokubanzi, kwaye isixhobo siguquguquka ngakumbi, kwaye impembelelo ilinganiselwe.

Ekulandeleni, kusekho iiveki ezimbini ukusuka kwiholide ye-11, kulo mjikelo wemarike ephezulu, abanye abathengi baye bagcinwa ngokulinganayo, kwaye kusekho inani elincinci lemfuno kule veki, kwaye ukuphela kwenyanga kusondela. ixesha leeholide, kwaye imarike kulindeleke ukuba ibe kwiholide enye emva kwenye.

Okwesine, ukunyuka kunokunciphisa ngaphambi komthendeleko wokuzinzisa okanye uluhlu oluncinci

Isiphelo (ixesha elifutshane) : Kwiveki ephelileyo, ixabiso lemarike elinyukayo liye lanyuka laya kwindawo entsha ephezulu kwisiqingatha sesibini sonyaka, kwaye kutshanje, i-standoff kulindeleke ukuba ibuyele ekuzinzeni, kule veki, kusekho inani elincinci lempahla. imfuno yokuphela kwe-polyether, i-CIC kulindeleke ukuba ibe yi-standoff, ngasekupheleni kwenyanga, amaqela axhasa ubuthathaka, okanye kukho ukuhla okulindelweyo.

Isiphelo (eliphakathi kunye nexesha elide) : Ngo-Oktobha, kufuneka sinikele ingqalelo ekuguquguqukeni kwezixhobo ezahlukeneyo ngexesha leeholide, iTianjin Bohua kulindeleke ukuba iqalise kwakhona emva kweholide, uShandong Jinling unokuba nolindelo lokugcina, ubuyele kuluhlu oluncinci emva kwesitoko. iyalungiswa, kwaye ukugcinwa kweShell kwisiqingatha sesibini sonyaka, kuthathelwe ingqalelo uphuhliso oluthile.

Isilumkiso somngcipheko: ukungaqiniseki kwenodi yexesha elongezelelweyo kumphezulu wesixhobo; Ukuba uxinzelelo lweendleko emva komdla woshishino ukuqala; Ibango icala lokwenyani lokufika.
