Kule veki, ixabiso leemveliso kwishishini le-phenol-ketone ngokubanzi liye lehla. Ukudlula kweendleko ezibuthathaka, kunye noxinzelelo lokubonelela kunye nemfuno, kubeke uxinzelelo oluthile lohlengahlengiso oluphantsi kumaxabiso eshishini le-industrial. Nangona kunjalo, iimveliso ezisezantsi zibonise ukumelana okukhulu nokwehla xa kuthelekiswa nezo zisezantsi, nto leyo ekhokelele ekwehleni kwenzuzo kumashishini asezantsi. Nangona umda wokulahleka kweshishini le-phenol-ketone eliphakathi uye wehla, inzuzo iyonke yeemveliso ezisezantsi neziphakathi ihlale ibuthathaka, ngelixa amashishini asezantsi e-MMA (Methyl Methacrylate) kunye ne-isopropanol asagcina inzuzo ethile.
Ngokuphathelele amaxabiso aphakathi evekini, ngaphandle kokunyuka okuncinci kwixabiso eliphakathi evekini le-phenol (imveliso ephakathi), zonke ezinye iimveliso kwi-phenol-ketone industrial chain zirekhode ukwehla, uninzi lwazo luwela phakathi kwe-0.05% ukuya kwi-2.41%. Phakathi kwazo, iimveliso ezisezantsi ze-benzene kunye ne-propylene zombini zibuthathaka, kunye namaxabiso azo aphakathi evekini ehla nge-0.93% kunye ne-0.95% inyanga nenyanga ngokulandelelana. Ngeveki, emva kokunyuka okuncinci ngokulandelelanayo, amaxabiso e-oyile eluhlaza yekamva abone ukwehla kwexesha elifutshane okwandisiweyo. Iimeko zemarike zokugqibela zahlala zicotha, kwaye imvakalelo yokuqapha yayinamandla. Nangona kunjalo, imfuno yokuxuba ipetroli yase-US inyuse amaxabiso e-toluene, kwaye iiyunithi zokungalingani zavalwa ngenxa yeenzuzo zoqoqosho ezimbi, nto leyo ekhokelele ekubuyeni kwamaxabiso e-benzene ngasekupheleni kweveki. Okwangoku, ezinye iiyunithi ze-propylene ezingasebenziyo zaqala ukusebenza, zinyusa kancinci inkxaso yemfuno ye-propylene. Ngokubanzi, nangona ukuphela kwezinto eziluhlaza kwabonisa umkhwa wobuthathaka, ukwehla kwakuncinci kuneemveliso ezisezantsi.
Iimveliso eziphakathi i-phenol kunye ne-acetone ikakhulu zirhweba ecaleni, kunye nokuguquguquka okuncinci kutshintsho lwamaxabiso azo aphakathi evekini. Nangona iindleko ziphantsi, ezinye iiyunithi ze-bisphenol A ezisezantsi zaqala ukusebenza, kwaye bekukho amathemba okugcinwa kweeyunithi ze-phenol-ketone ze-Hengli Petrochemical kwixesha elizayo. Izinto ezinde nezimfutshane zadibana kwimarike, nto leyo ekhokelele ekungqubaneni phakathi kwabathengi nabathengisi. Iimveliso ezisezantsi zibona umkhwa ocacileyo wokuhla kunexabiso ngenxa yokubonelela okwaneleyo kunye nokungabikho kophuculo kwimfuno yokugqibela. Kule veki, ixabiso eliqhelekileyo leveki leshishini le-MMA elisezantsi lehle nge-2.41% inyanga nenyanga, ukwehla okukhulu kweveki kwikhonkco lemizi-mveliso. Oku kwakubangelwa ikakhulu kukungabikho kokufuna ekupheleni, okwabangela ukunikezelwa okwaneleyo kwimarike yendawo. Ngokukodwa, iifektri eziseShandong zijongene noxinzelelo olukhulu lwezinto ezisetyenzisiweyo kwaye kwafuneka zinciphise iikowuteshini ukuze kukhuthazwe ukuthunyelwa. Amashishini e-bisphenol A kunye ne-isopropanol asezantsi nawo afumene iindlela ezithile zokuhla, kunye nokwehla kwamaxabiso okuphakathi kweveki nganye kwe-2.03% kunye ne-1.06% ngokwahlukeneyo, njengoko imakethi ihlale ikwimeko yokuguquguquka okuphantsi phakathi koxinzelelo lokubonelela kunye nemfuno.
Ngokuphathelele inzuzo kushishino, phakathi evekini, echatshazelwe yimpembelelo ye-bearish yokunyuka koxinzelelo lokubonelela kunye nemfuno kumashishini asezantsi kunye nokudluliselwa kweendleko ezibuthathaka, inzuzo yeemveliso ezisezantsi kuluhlu lwemizi-mveliso ibonise ukuhla. Nangona umda wokulahleka kweshishini eliphakathi le-phenol-ketone uphucukile, inzuzo iyonke yethiyori yecandelo lemizi-mveliso yehle kakhulu, kwaye uninzi lweemveliso kuluhlu luhlale lukwimeko yokulahleka, nto leyo ebonisa inzuzo ebuthathaka yecandelo lemizi-mveliso. Phakathi kwazo, ishishini le-phenol-ketone libhale ukwanda okukhulu kwenzuzo: ilahleko yethiyori yeshishini kule veki yayiyi-357 yuan/ton, incipha nge-79 yuan/ton xa ithelekiswa neveki ephelileyo. Ukongeza, inzuzo yeshishini le-MMA elisezantsi yehle kakhulu, kunye ne-avareji yenzuzo iyonke yethiyori yeshishini kwi-92 yuan/ton, ukwehla kwe-333 yuan/ton ukusuka kwiveki ephelileyo. Ngokubanzi, inzuzo yangoku yecandelo lemizi-mveliso le-phenol-ketone ibuthathaka, uninzi lweemveliso zisabambeke kwilahleko. Yimizi-mveliso ye-MMA kunye ne-isopropanol kuphela enenzuzo yethiyori engaphezulu kancinci komgca we-break-even.
Ingqwalasela ephambili: 1. Kwixesha elifutshane, amaxabiso e-oyile ekrwada kwixesha elizayo anokuthi ahlale etshintshatshintsha kwaye ebuthathaka, kwaye iindleko ezibuthathaka kulindeleke ukuba ziqhubeke zisihla. 2. Uxinzelelo lobonelelo lweshishini lusekhona, kodwa amaxabiso eemveliso zeshishini aphantsi kakhulu kwiminyaka emininzi, ngoko ke indawo yokwehla kwamaxabiso inokuncipha. 3. Kunzima kumashishini abasebenzisi bokugqibela ukubona uphuculo olukhulu, kwaye imfuno ebuthathaka inokuqhubeka nokufaka impendulo engalunganga phezulu.
