Intshayelelo: Imakethi ye-benzene ecocekileyo yamva nje iyaqhubeka nokukhula, kwaye icala leendleko lenza inkxaso eyomeleleyo kwimakethi yecaprolactam, kwaye imakethi yecaprolactam ilandela indlela yokunyuka. Amandla aphambili axhasayo emakethe kade asekho kwicala leendleko, kulindeleke ukuba imarike ye-caprolactam iya kuqhuba ngamandla kwixesha elizayo, kwaye amandla aqhubekayo okunyuka kweendleko kunye nenkqubo yokuhanjiswa kwe-downstream iya kukhathazeka kwinqanaba elilandelayo.
Ukusukela ngoJulayi, imarike yebenzene esulungekileyo yonyuswe zizinto ezininzi ezifana nokunyuka kwe-oyile ekrwada, ukuphuculwa konikezelo kunye nepateni yemfuno kunye nefuthe leendaba ezihambelana nerhafu yokusetyenziswa kwimfuno ye-ethylbenzene, kunye nemarike yebenzene esulungekileyo iye yaqhubeleka. ukuphakama. Ixabiso leSinopec elisulungekileyo lebenzene elidwelisiweyo ukusukela ekuqaleni kwenyanga i6200 yuan/ton yenyuka ukuya kwi6950 yuan/ton yangoku.
Ixabiso le-benzene ecocekileyo liyaqhubeka nokunyuka, iindleko ze-caprolactam zamashishini zonyukile, kwaye ixabiso leemveliso linyukile. Okwangoku, ixabiso lendawo ye-caprolactam eMpuma yeChina linyuke laya kufutshane ne-12300 yuan/toni, kwaye ezinye iinqanawa ze-caprolactam emantla ziqinile kancinci, kwaye umdla wokuthengwa kwempahla osezantsi ulungile kwinkqubo ephezulu, kwaye umzi-mveliso wepolymerization ulandela ngokusisiseko. njengoko kufuneka.
Ngokuqalwa kwakhona kweLuxi Chemical Industry, iCangzhou Xuyang Phase I kunye nezinye izixhobo, izinga lokusebenzisa umthamo we-caprolactam linyuke laya kutsho kwi-81.35%, ngaphandle kwezinye izixhobo zokupaka ixesha elide zisekwimeko yokupaka, ezinye izixhobo zisebenza ngokuqhelekileyo. Nangona kunjalo, ngenxa yoluhlu oluphantsi lwe-caprolactam kwinqanaba lokuqala, kunye nemarike yangoku ikwindlela ephezulu, kunye nokukhethwa kwe-downstream yokuthengwa kwempahla, indawo esemantla yobonelelo isaqinile kancinci.
Inqanaba lokusetyenziswa kwepolymerization yePA6 isandula kunyuka ngokuhambelanayo, kwelinye icala, imfuno efunwayo yesantya esiphezulu sokujikeleza ezantsi komsinga iyaqhubeka nokuxhasa ukuqala kwepolymerization, kwelinye icala, isixhobo sokuqala sokupaka iLuxi Chemical siqale kancinci kancinci, kwaye Inqanaba lokusetyenziswa komthamo we-PA6 linyukile laya kufutshane ne-76%, kwaye imveliso yeveki yokunqunyulwa kunye nemveliso yeveki ye-caprolactam iye yanda ngokuhambelanayo ukuya kufutshane ne-100,000 yeetoni.
Umthwalo wentsila yenayiloni esezantsi uhleli uzinzile, kwaye umyinge okhoyo wangoku wasekhaya womthwalo womthwalo wenayiloni umalunga nama-79.5%. Izinga elibanzi lokusebenza lwe-chemical fiber weaving kwimimandla ye-Jiangsu kunye ne-Zhejiang yayingu-63.47%, phantsi kwe-0.40% ukusuka kwiveki ephelileyo. Ukwaluka kuqale ukwehla okuncinci, kodwa utshintsho lulonke luncinci, ukuluka kwetheminali yangoku akuchatshazelwa kulwabiwo lwamandla, abasebenzisi abasezantsi kakhulu bakwinqanaba lokulinda kunye nokulinda-nokubona, belinde urhwebo lwasekhaya kunye nolwangaphandle ukhululo olutsha oluphakathi.
Isishwankathelo, amandla enkxaso yemakethe ye-caprolactam yangoku ivela kwicala leendleko, i-caprolactam kunye ne-PA6 i-polymerization umthamo wokusetyenziswa kwesantya sonyuka ngokuhambelanayo, ukunikezelwa kwe-caprolactam kunye nemfuno ngokusisiseko, kulindeleke ukuba imarike ye-caprolactam yomelele kwixesha elizayo. Ummandla ojikelezayo osezantsi uzinzile, kwaye akukho tshintsho lubalulekileyo ekulindelweni kwemfuno yezinto ekrwada, kwaye intsimi ye-speed spinning isakwazi ukulandela. Intsimi yelaphu yesiqhelo isacotha ukulandela, kwaye ngokunyuka kobonelelo kunye noxinzelelo lokhuphiswano, kusekho ukuxhathisa ukuhanjiswa okuhlayo kwamaxabiso aphezulu. Kwinqanaba lokugqibela, kusafuneka ukuba ubeke ingqalelo kumandla aqhubekayo okunyuka kweendleko kunye nenkqubo yokudlulisela ukuya ezantsi.
