Isingeniso: Imakethe ye-benzene emsulwa yakamuva iyaqhubeka nokwenyuka, kanti uhlangothi lwezindleko lwakha ukwesekwa okuqinile kwemakethe ye-caprolactam, kanti imakethe ye-caprolactam ilandela ukuthambekela okukhuphukayo. Amandla ayinhloko okusekela emakethe yamuva asesehlangothini lwezindleko, kulindeleke ukuthi imakethe ye-caprolactam isebenze kakhulu esikhathini esizayo esiseduze, futhi amandla aqhubekayo okunyuka kwezindleko kanye nenqubo yokudlulisela engezansi kuzokhathazeka esigabeni esilandelayo.

Kusukela ngoJulayi, imakethe ye-benzene emsulwa ikhuliswe yizici eziningi ezifana nokwenyuka kukawoyela ongahluziwe, ukuthuthukiswa kwephethini yayo yokuphakelwa kanye nesidingo kanye nomthelela wezindaba ezihlobene nentela yokusetshenziswa ekudingweni kwe-ethylbenzene, kanye nemakethe ye-benzene emsulwa iqhubekile nokukhuphuka. Intengo ebhalwe ku-Sinopec pure benzene kusukela ekuqaleni kwenyanga inyuke yaba yi-6200 yuan/ton yamanje yaba yi-6950 yuan/ton.

Intengo ye-benzene emsulwa iyaqhubeka nokukhuphuka, izindleko zamabhizinisi e-caprolactam zikhuphukile, futhi intengo yemikhiqizo ikhuphukile. Njengamanje, intengo ye-caprolactam eMpumalanga yeShayina ikhuphukile yafinyelela cishe ku-12300 yuan/ton, kanti okunye ukuthunyelwa kwe-caprolactam enyakatho kuncane kancane, futhi intshiseko yokuthengwa kwemikhiqizo engezansi ilungile enkambisweni yokwenyuka, futhi imboni ye-polymerization ilandela ngokuyisisekelo njengoba kudingeka.

Ngokuqala kabusha kwe-Luxi Chemical Industry, i-Cangzhou Xuyang Phase I kanye namanye amadivayisi, izinga lokusetshenziswa kwamandla e-caprolactam lenyuke laya ku-81.35%, ngaphandle kwamanye amadivayisi okupaka isikhathi eside asesesesimweni sokupaka, amanye amadivayisi asebenza ngokujwayelekile. Kodwa-ke, ngenxa yohlu oluphansi lwe-caprolactam esigabeni sokuqala, kanye nemakethe yamanje isekukhuphukeni, kanye nokukhetha okuthandwayo kokuthengwa kwempahla, ingxenye esenyakatho yokuphakelwa isalokhu incane.

Izinga lokusetshenziswa komthamo we-polymerization we-PA6 lisanda kukhuphuka ngokuhamba kwesikhathi, ngakolunye uhlangothi, ukuthandwa kwesidingo sokujika okusheshayo okuya phansi kuyaqhubeka nokusekela ukuqala kwe-polymerization, ngakolunye uhlangothi, idivayisi yokupaka yasekuqaleni ye-Luxi Chemical iqale kabusha kancane kancane, kanti izinga lokusetshenziswa komthamo we-PA6 likhuphuke laya cishe ku-76%, kanti umkhiqizo wokusika wamasonto onke kanye nomkhiqizo wamasonto onke we-caprolactam kukhuphuke ngokuhamba kwesikhathi kwaya cishe ku-100,000 amathani.

Umthwalo we-filament ye-nylon ongezansi uhlala uzinzile, kanti umthwalo we-filament ye-nylon ojwayelekile wasekhaya ucishe ube ngu-79.5%. Izinga lokusebenza eliphelele lokuluka i-fiber yamakhemikhali ezifundeni zaseJiangsu naseZhejiang lalingu-63.47%, lehle ngo-0.40% kusukela ngesonto eledlule. Ukuluka kuqale ukwehla okuncane, kodwa ushintsho oluphelele luncane, ukuluka kwe-terminal kwamanje akuthinteki ngokulinganiswa kwamandla, abasebenzisi abaphansi basesigabeni sokulinda nokubona, balinde ukuhweba kwasekhaya nakwamanye amazwe ukukhishwa okusha okuhlanganisiwe.

Ngamafuphi, amandla okusekela emakethe ye-caprolactam amanje avela ohlangothini lwezindleko, izinga lokusetshenziswa kwamandla e-caprolactam kanye ne-PA6 polymerization landa ngokuvumelana, ukuhlinzekwa kanye nesidingo se-caprolactam ngokuyisisekelo kuyalingana, kulindeleke ukuthi imakethe ye-caprolactam iqine maduze nje. Insimu yokuphotha engezansi izinzile, futhi akukho shintsho olubalulekile ekulindelweni kwesidingo sezinto zokusetshenziswa, futhi insimu yokuphotha eshesha kakhulu isakwazi ukulandelela. Insimu yendwangu evamile isalokhu ihamba kancane ukulandelela, futhi ngokwanda kokunikezwa kanye nengcindezi yokuncintisana, kusekhona ukumelana nokudluliselwa kwentengo ephezulu ehlayo. Esigabeni sakamuva, kusadingeka ukunaka amandla aqhubekayo okwanda kwezindleko kanye nenqubo yokudlulisela engezansi.
