Ngaphambi komnyhadala, ixabiso lemarike ye-MMA lenyuka, ukusuka kwicala leendleko, ngoDisemba 29, ireferensi ye-acetone yeJiangsu iphantse ibe yi-7000 yuan/ton, inkxaso yeendleko ilungile. Kodwa ayisiyonto iphambili ekunyuseni kwamaxabiso. Icala lokubonelela lalilawula umkhwa wemarike ngoDisemba, ngenxa yesantya esiphantsi sokusetyenziswa komzi-mveliso, kunye nokuqaliswa kwakhona kweZhejiang Petrochemical ngaphambi kweholide, indawo yokupaka yexeshana yaseShandong Hongxu, icala lokubonelela laliqiniswe ngakumbi, kwaye isantya sokusetyenziswa komthamo sasiyi-48% kwiveki engaphambi kweholide. Izibonelelo zomgangatho ziqhubekile nokunyuka kancinci ekupheleni kwenyanga emva kokunyuka okukhulu ngoDisemba. Imarike yesibini yaseMpuma China, ngoDisemba 29 xa ithelekiswa neDisemba 22 inyuke nge-125 yuan/ton, ukunyuka okuhlangeneyo kwe-1500 yuan/ton kwiinyanga ezimbalwa.

Ngokuphathelele iimveliso zesiphelo, nangona amashishini asezantsi enokunyuka okwahlukeneyo, ukuhanjiswa kweendleko kuyacotha, kwaye ukunyuka kungaphantsi kotshintsho lwezinto eziluhlaza, ukuthunyelwa okuphezulu kweemveliso zesiphelo kubanzi, kwaye ukuthengwa kwezinto eziluhlaza kuyagcinwa. Ukusukela nge-29 kaDisemba, ingqwalasela ye-PMMA particle market talks yayigxile kwi-14500-15700 yuan/ton, kwaye kusekho ezinye izibonelelo eziphezulu kancinci. I-emulsion ye-acrylic ecocekileyo inyuke kancinci, kunye nokukhula okuncinci, ixabiso liyi-7500-9100 yuan/ton.

Ukususela nge-28 kaDisemba, izinga eliqhelekileyo lokusetyenziswa kwamandla ngeveki kwishishini le-MMA yayiyi-48%, inzuzo iyonke yenkqubo ephindwe kabini inyukile, kwaye inzuzo iyonke yendlela ye-ACH kunye nendlela ye-C4 yayiyi-1308 yuan/ton kunye ne-1667 yuan/ton, ngokulandelelana, eyehla nge-+13.63% kunye ne-+40.00% xa kuthelekiswa ne-21 kaDisemba. Isizathu esiphambili sokwanda kwenzuzo iyonke kungenxa yokunyuka kwexabiso le-MMA elixhaswa lubonelelo, ukongeza ekunyukeni kwenkqubo ye-ACH, izinto ezikrwada zenkqubo ye-C4 ziyehla, ngoko ke ukunyuka nokuhla kwahlukile.

Ekupheleni komsinga, ukusukela nge-28 kaDisemba, ngenxa yokubuyiselwa nokuqaliswa kwakhona kwezinye izixhobo kwiveki yokugqibela ngaphambi komnyhadala, izinga lokusetyenziswa komthamo weveki wezixhobo ze-phenol ketone lonyuke ngama-3 ekhulwini ukuya kwi-71%. Inzuzo iyonke ye-phenol ketone yayiyi-211.5 yuan/ton, yehle ngama-66.82% ukusuka kwikota edlulileyo. Ixabiso linokuxhaswa yi-MMA.

Kwicala elisezantsi, iinxalenye ze-PMMA kunye ne-acrylic emulsion zaqala ngokuzinzileyo, kwaye inzuzo iyonke yanda kancinci, ikakhulu ngenxa yokunyuka kwexabiso layo. Ukusukela nge-28 kaDisemba, inzuzo iyonke yeenxalenye ze-PMMA kunye ne-styrene acrylic emulsion yayingama-392 yuan/ton kunye nama-605 yuan/ton ngokulandelanayo.

Ngamafutshane, ngokutsho kokubeka esweni idatha yaseLongzhong, inqanaba lenzuzo yenkqubo ephindwe kabini ye-MMA ngaphambi komnyhadala liphezulu kakhulu kunelo leentlobo ezisezantsi neziphezulu.

Ngaphambi komnyhadala, ezinye izixhobo zasefektri okanye ukugcinwa okanye ukungabikho kwezixhobo, iZhejiang ilibazise ukuqala kwakhona, indawo yokupaka yexeshana yaseShandong Hongxu, icala lokubonelela laqiniswa ngakumbi. Ukunikezelwa kwendawo esemgangathweni kwanele, kwaye ingqwalasela yengxoxo iyatshintshwa. Emva kweholide, umzi-mveliso waseShandong ucwangcise ukuqalisa kwakhona, ukulandelelana okunamandla kwezixhobo zeZhejiang Petrochemical kunye nezinye izixhobo zeMMA. Icala lokubonelela ngexesha elifutshane kunzima ukulibuyisela ngokupheleleyo, kwaye kusekho inkxaso ethile kwimarike, imakethi yexesha elifutshane iphezulu, kwaye ukuguquguquka kwezixhobo zasefektri kuyaxhalabisa.
