Ngaphambi komkhosi, intengo yemakethe ye-MMA yakhuphuka, kusukela ohlangothini lwezindleko, ngoDisemba 29, ireferensi ye-acetone yeJiangsu iseduze ne-7000 yuan/ton, ukwesekwa kwezindleko kulungile. Kodwa akuyona imbangela enkulu yokwenyuka kwentengo. Uhlangothi lokuhlinzeka lubuse ukuthambekela kwemakethe ngoDisemba, ngenxa yesilinganiso sokusetshenziswa kwamandla aphansi efektri, kuhlanganiswe nokuqala kabusha kweZhejiang Petrochemical ngaphambi kweholide, ukupaka okwesikhashana kweShandong Hongxu, uhlangothi lokuhlinzeka lwaqiniswa kakhulu, kanti isilinganiso sokusetshenziswa kwamandla sasingu-48% ngesonto ngaphambi kweholide. Izipesheli zephansi zaqhubeka nokukhuphuka kancane ekupheleni kwenyanga ngemuva kokwenyuka okukhulu ngoDisemba. Imakethe yesibili yase-East China, ngoDisemba 29 uma kuqhathaniswa noDisemba 22 yakhuphuka ngo-125 yuan/ton, ukwanda okuhlangene okungu-1500 yuan/ton phakathi nezinyanga.

Ngokuphathelene nemikhiqizo ye-terminal, yize izimboni ezingezansi zinokwenyuka okuhlukile, ukudluliselwa kwezindleko kuyabambezeleka, futhi ukwenyuka kuncane kunoshintsho lwezinto zokusetshenziswa, ukuthunyelwa okuphezulu kwemikhiqizo ye-terminal kuyinto evamile, futhi ukuthengwa kwezinto zokusetshenziswa kuyagcinwa. Kusukela ngoDisemba 29, izingxoxo zemakethe ye-PMMA particle East China zazigxile ku-14500-15700 yuan/ton, futhi kusenezipesheli ezithile eziphakeme kancane. I-emulsion ye-acrylic emsulwa ikhuphuke kancane, ngokukhula okulinganiselwe, intengo ingu-7500-9100 yuan/ton.

Kusukela ngoDisemba 28, isilinganiso sokusetshenziswa kwamandla masonto onke embonini ye-MMA sasingu-48%, inzuzo iyonke yenqubo ephindwe kabili yanda, kanti inzuzo iyonke yendlela ye-ACH kanye nendlela ye-C4 yayingu-1308 yuan/ton kanye no-1667 yuan/ton, ngokulandelana, okwehle ngo-+13.63% kanye no-+40.00% uma kuqhathaniswa noDisemba 21. Isizathu esiyinhloko sokwanda kwenzuzo iyonke kungenxa yokwanda kwentengo ye-MMA esekelwa ukuphakelwa, ngaphezu kokwanda kwenqubo ye-ACH, izinto zokusetshenziswa zenqubo ye-C4 zehle, ngakho-ke ukukhuphuka nokwehla kuhlukile.

Ekupheleni komfula, kusukela ngoDisemba 28, ngenxa yokubuyiselwa nokuqaliswa kabusha kwamanye amadivayisi ngesonto eledlule ngaphambi komkhosi, isilinganiso sokusetshenziswa kwamandla amadivayisi e-phenol ketone samasonto onke sanda ngamaphuzu angu-3% saya ku-71%. Inzuzo iyonke ye-phenol ketone yayingu-211.5 yuan/ton, yehle ngo-66.82% kusukela kwikota edlule. Izindleko zingasekelwa yi-MMA.

Ekugcineni komfula, izinhlayiya ze-PMMA kanye ne-acrylic emulsion kwaqala ngokuqina, futhi inzuzo enkulu yanda kancane, ikakhulukazi ngenxa yokwenyuka kwentengo yayo. Kusukela ngomhlaka-28 Disemba, inzuzo enkulu yezinhlayiya ze-PMMA kanye ne-styrene acrylic emulsion yayingama-yuan angu-392/ton kanye nama-yuan angu-605/ton ngokulandelana.

Ngamafuphi, ngokusho kokuqapha idatha yeLongzhong, izinga lenzuzo yenqubo ephindwe kabili ye-MMA ngaphambi komkhosi liphakeme kakhulu kunelezinhlobo ezingenhla nezingezansi.

Ngaphambi komkhosi, eminye imishini yasefektri noma ukulungiswa noma okubi, iZhejiang yalibazisa ukuqala kabusha, indawo yokupaka yesikhashana yaseShandong Hongxu, uhlangothi lokunikezwa lwaqiniswa kakhulu. Ukunikezwa kwendawo phansi kwanele, futhi ukugxila kwengxoxo kuyashintshwa. Ngemuva kweholide, ifektri yaseShandong isanda kuhlela ukuqala kabusha, ukulandelwa okunamandla kwamadivayisi e-Zhejiang Petrochemical namanye ama-MMA. Uhlangothi lokunikezwa kwesikhashana kunzima ukulubuyisela ngokuphelele, futhi kusekhona ukwesekwa kwemakethe, imakethe yesikhashana iphakeme kakhulu, futhi ukuguquguquka kwemishini yasefektri kuyathinteka.
