Ngaphambi komthendeleko, ixabiso lemarike ye-MMA lenyuka, ukusuka kwicala leendleko, ngoDisemba 29, ireferensi ye-acetone ye-Jiangsu kufuphi ne-7000 yuan / ton, inkxaso yeendleko ilungile. Kodwa akuyena umqhubi oyintloko wokunyuka kwamaxabiso. Icala lonikezelo lilawule indlela yentengiso ngoDisemba, ngenxa yomgangatho ophantsi wokusetyenziswa komzi-mveliso, udityaniswa nokulibaziseka kokuqaliswa kwe-Zhejiang Petrochemical ngaphambi kweholide, i-Shandong Hongxu yokupaka okwethutyana, icala lokubonelela liye laqiniswa ngakumbi, kunye nokusetyenziswa komthamo ophakathi. izinga lalingama-48% kwiveki ephambi kweholide. Ukunikezelwa komgangatho kuqhubekile ukunyuka kancinci ekupheleni kwenyanga emva kokunyuka okubanzi ngoDisemba. Imarike yase-East China yesibini, nge-29 kaDisemba xa kuthelekiswa ne-22 kaDisemba yenyuka nge-125 yuan/toni, ukunyuka okunyukayo kwe-1500 yuan/toni kwiinyanga.

Ngokweemveliso ze-terminal, nangona amashishini asezantsi anokunyuka okwahlukileyo, ukuhanjiswa kweendleko kuncinci, kwaye ukonyuka kungaphantsi kotshintsho lwempahla ekrwada, ukuthunyelwa okuphezulu kweemveliso ze-terminal kubanzi, kwaye ukuthengwa kwempahla ekrwada kuyagcinwa. . Ukusukela nge-29 kaDisemba, ugqaliselo lwe-PMMA yesuntswana eMpuma China uthethathethwano lwemarike lugxile kwi-14500-15700 yuan/toni, kwaye kusekho izibonelelo ezingaphezulu kancinci. I-emulsion ye-acrylic ecocekileyo yenyuka kancinane, ngokukhula okulinganiselwe, ixabiso li-7500-9100 yuan / ton.

Ukusukela nge-28 kaDisemba, umyinge wokusetyenziswa kwamandla eveki kwishishini leMMA yayingama-48%, inzuzo epheleleyo yenkqubo ephindwe kabini yenyuka, kunye nengeniso epheleleyo yendlela ye-ACH kunye nendlela yeC4 yayiyi-1308 yuan/ton kunye ne-1667 yuan/ton, ngokulandelelanayo. , eyawa ngo + 13.63% kunye + 40.00% xa kuthelekiswa noDisemba 21. Esona sizathu siphambili sokunyuka kwenzuzo enkulu kakhulu ngenxa yokunyuka kwexabiso le-MMA elixhaswa ngukubonelela, ngaphezu kokunyuka kwenkqubo ye-ACH, inkqubo ye-C4 eluhlaza. izinto zawa, ngoko ke ukunyuka nokuwa kuyahluka.

Ekupheleni komlambo, ukususela ngo-Disemba 28, ngenxa yokubuyiselwa kunye nokuqaliswa kwakhona kwezinye izixhobo kwiveki yokugqibela ngaphambi komthendeleko, i-avareji yeveki yokusetyenziswa kwamandla okusebenzisa izixhobo ze-phenol ketone zanda ngeepesenti ze-3 ukuya kwi-71%. Ingeniso ye-phenol ketone yayiyi-211.5 yuan / ton, phantsi kwe-66.82% ukusuka kwikota yangaphambili. Iindleko zinokuxhaswa yi-MMA.

Ekupheleni komlambo, iinqununu ze-PMMA kunye ne-emulsion ye-acrylic yaqala ukuzinza, kwaye inzuzo enkulu yanda kancinci, ngokukodwa ngenxa yokunyuka kwexabiso layo. Ukususela kwi-28 kaDisemba, inzuzo enkulu ye-PMMA particles kunye ne-styrene acrylic emulsion yayiyi-392 yuan / ton kunye ne-605 yuan / ton ngokulandelanayo.

Isishwankathelo, ngokutsho kwedatha ye-Longzhong yokubeka iliso, inqanaba lenzuzo yenkqubo ye-MMA kabini ngaphambi komthendeleko uphezulu kakhulu kuneentlobo ezinyukayo nezisezantsi.

Ngaphambi komthendeleko, ezinye izixhobo zefektri okanye ukugcinwa okanye okubi, uZhejiang ulibazise ukuqala kwakhona, i-Shandong Hongxu yokupaka okwethutyana, icala lokubonelela liqiniswe ngakumbi. Ukunikezelwa kwendawo emgangathweni kwanele, kwaye ugxininiso lothetha-thethwano lutshintshile. Emva kweholide, umzi-mveliso waseShandong kutshanje ucwangcise ukuphinda uqalise, iZhejiang Petrochemical kunye nezinye izixhobo zeMMA zokulandela okuguquguqukayo. Icala lonikezelo lwexesha elifutshane linzima ukubuyisela ngokupheleleyo, kwaye kusekho inkxaso kwimarike, imarike yexesha elifutshane iphezulu kakhulu, kwaye i-dynamics yezixhobo zefektri zichaphazelekayo.
