Intshayelelo: Imakethi ye-benzene ecocekileyo yakutshanje iyaqhubeka nokunyuka, kwaye icala leendleko lenza inkxaso enamandla kwimakethi ye-caprolactam, kwaye imakethi ye-caprolactam ilandela umkhwa onyukayo. Amandla aphambili axhasayo kwimakethi yamva nje asekwicala leendleko, kulindeleke ukuba imakethi ye-caprolactam isebenze ngamandla kwixesha elizayo, kwaye amandla aqhubekayo okunyuka kweendleko kunye nenkqubo yokuhambisa esezantsi kuya kukhathazeka kwinqanaba elilandelayo.

Ukususela ngoJulayi, imakethi ye-benzene ecocekileyo inyuswe zizinto ezininzi ezinje ngokunyuka kweoyile ekrwada, ukuphuculwa kwendlela yayo yokubonelela kunye nemfuno kunye nempembelelo yeendaba ezinxulumene nerhafu yokusebenzisa kwimfuno ye-ethylbenzene, kwaye imakethi ye-benzene ecocekileyo iqhubekile nokunyuka. Ixabiso elidweliswe yi-Sinopec pure benzene ukususela ekuqaleni kwenyanga i-6200 yuan/ton lenyuke laya kwi-6950 yuan/ton yangoku.

Ixabiso le-benzene ecocekileyo liyaqhubeka nokunyuka, ixabiso lamashishini e-caprolactam linyukile, kwaye ixabiso leemveliso linyukile. Okwangoku, ixabiso eliphantsi le-caprolactam eMpuma China linyuke laya kufutshane ne-12300 yuan/ton, kwaye ezinye ii-caprolactam ezithunyelwa emantla zincinci kancinci, kwaye umdla wokuthengwa kwezinto ulungile kwinkqubo yokunyuka, kwaye umzi-mveliso we-polymerization ulandela ngokusisiseko njengoko kufuneka.

Ngokuqala kwakhona kweLuxi Chemical Industry, iCangzhou Xuyang Phase I kunye nezinye izixhobo, izinga lokusetyenziswa komthamo we-caprolactam linyuke laya kwi-81.35%, ngaphandle kwezinye izixhobo zokupaka ixesha elide zisekwimeko yokupaka, ezinye izixhobo zisebenza ngokuqhelekileyo. Nangona kunjalo, ngenxa yokuba uluhlu oluphantsi lwe-caprolactam lukwinqanaba lokuqala, kunye nemarike yangoku ikwimeko yokunyuka, kwaye ukhetho lokuthengwa olusezantsi, inxalenye esemantla yobonelelo isancinci.

Izinga lokusetyenziswa komthamo we-polymerization ye-PA6 linyuke kutshanje ngokulandelelana, kwelinye icala, ukhetho lwemfuno yokujikeleza ngesantya esiphezulu ezantsi luyaqhubeka nokuxhasa ukuqala kwe-polymerization, kwelinye icala, isixhobo sokupaka kwangoko seLuxi Chemical siye saqala kwakhona kancinci kancinci, kwaye izinga lokusetyenziswa komthamo we-PA6 linyuke laya kufutshane ne-76%, kwaye imveliso yokusika iveki nganye kunye nemveliso yeveki ye-caprolactam inyuke ngokulinganayo yaya kufutshane ne-100,000 yeetoni.

Umthwalo we-nylon filament osezantsi uhlala uzinzile, kwaye umthwalo we-nylon filament ophakathi wasekhaya umalunga ne-79.5%. Izinga lokusebenza elipheleleyo lokuluka iifayibha zamakhemikhali kwimimandla yaseJiangsu naseZhejiang yayiyi-63.47%, yehle nge-0.40% ukusuka kwiveki ephelileyo. Ukuluka kuqale ukwehla okuncinci, kodwa utshintsho lulonke luncinci, ukuluka kwe-terminal yangoku akuchaphazeleki kukwahlulwa kwamandla, abasebenzisi abasezantsi bakwinqanaba lokulinda nokubona, belinde urhwebo lwasekhaya nolwangaphandle ukukhululwa okutsha okuphakathi.

Ngamafutshane, amandla enkxaso yemarike ye-caprolactam akhoyo ngoku avela kwicala leendleko, izinga lokusetyenziswa kwamandla e-caprolactam kunye ne-PA6 polymerization landa ngokulandelelana, ukunikezelwa kunye nemfuno ye-caprolactam ngokusisiseko zilinganisiwe, kulindeleke ukuba imakethi ye-caprolactam ibe namandla kwixesha elizayo elingekude. Intsimi yokujikeleza esezantsi izinzile, kwaye akukho tshintsho lubalulekileyo kwimfuno yezinto eziluhlaza ezilindelweyo, kwaye intsimi yokujikeleza ekhawulezayo isakwazi ukulandelela. Intsimi yelaphu eqhelekileyo isacotha ukulandelela, kwaye ngokwanda kokunikezelwa kunye noxinzelelo lokhuphiswano, kusekho ukumelana nokuhanjiswa okuphantsi kwamaxabiso aphezulu. Kwinqanaba lokugqibela, kusafuneka kuthathelwe ingqalelo amandla aqhubekayo okunyuka kweendleko kunye nenkqubo yokudlulisela esezantsi.
