Taw qhia: Kev ua lag luam tsis ntev los no cov dej ntshiab benzene tseem nce ntxiv, thiab tus nqi sab hauv cov ntaub ntawv muaj zog txhawb kev lag luam caprolactam, thiab caprolactam kev ua lag luam ua raws li kev nce qib. Lub zog txhawb nqa tseem ceeb ntawm kev ua lag luam lig tseem yog los ntawm tus nqi sab, nws xav tias kev lag luam caprolactam yuav khiav tau zoo nyob rau yav tom ntej, thiab lub zog txuas ntxiv ntawm cov nqi nce thiab cov txheej txheem xa mus rau hauv qab yuav muaj kev txhawj xeeb nyob rau theem tom ntej.

Txij li thaum Lub Xya Hli, kev lag luam ntshiab benzene tau txhawb nqa los ntawm ntau yam xws li kev nce hauv cov roj crude, kev txhim kho ntawm nws tus kheej cov khoom siv thiab kev xav tau qauv thiab kev cuam tshuam ntawm kev noj se cov xov xwm ntawm ethylbenzene xav tau, thiab kev lag luam ntshiab benzene tau txuas ntxiv mus. sawv. Sinopec ntshiab benzene teev nqi txij thaum pib ntawm lub hli 6200 yuan / tuj tau nce mus rau tam sim no 6950 yuan / tuj.

Tus nqi ntawm cov ntshiab benzene tseem nce ntxiv, tus nqi ntawm cov tuam txhab caprolactam tau nce, thiab tus nqi ntawm cov khoom tau nce. Tam sim no, tus nqi ntawm caprolactam nyob rau sab hnub tuaj Suav teb tau nce mus txog ze li ntawm 12300 yuan / tuj, thiab qee qhov kev xa khoom caprolactam nyob rau sab qaum teb yog me ntsis nruj, thiab cov khoom siv qis qis qis yog OK nyob rau hauv cov txheej txheem nce, thiab lub Hoobkas polymerization pib ua raws li. raws li xav tau.

Nrog rau kev rov pib dua ntawm Luxi Tshuaj Kev Lag Luam, Cangzhou Xuyang Phase I thiab lwm yam khoom siv, caprolactam muaj peev xwm siv tau nce mus rau 81.35%, tshwj tsis yog qee qhov chaw nres tsheb mus sij hawm ntev tseem nyob hauv lub xeev nres tsheb, lwm yam khoom siv tau pib ua haujlwm ib txwm. Txawm li cas los xij, vim tias cov khoom lag luam qis ntawm caprolactam nyob rau theem pib, ua ke nrog kev ua lag luam tam sim no nyob rau hauv ib qho kev nce siab, thiab qhov kev nyiam ntawm cov khoom siv qis qis, sab qaum teb ntawm cov khoom tseem yog me ntsis nruj.

PA6 polymerization muaj peev xwm siv tau tsis ntev los no tau nce synchronously, ntawm ib sab, qhov kev xav tau ntawm kev kub ceev spinning downstream txuas ntxiv txhawb qhov pib ntawm polymerization, ntawm qhov tod tes, qhov chaw nres tsheb thaum ntxov ntawm Luxi Chemical tau maj mam rov pib dua, thiab PA6 muaj peev xwm siv tau nce mus txog ze li 76%, thiab cov khoom tso tawm txhua lub limtiam thiab caprolactam cov zis txhua lub limtiam tau nce synchronously ze rau 100,000 tons.

Lub downstream nylon filament load tseem ruaj khov, thiab tam sim no domestic nruab nrab nylon filament load yog hais txog 79.5%. Kev ua haujlwm zoo ntawm cov tshuaj fiber ntau hauv cheeb tsam Jiangsu thiab Zhejiang yog 63.47%, nqis 0.40% ntawm lub lim tiam dhau los. Weaving pib poob me me, tab sis qhov kev hloov tag nrho yog me ntsis, qhov tam sim no lub davhlau ya nyob twg weaving tsis cuam tshuam los ntawm lub hwj chim rationing, downstream cov neeg siv feem ntau nyob rau hauv lub tos thiab tos-thiab-saib theem, tos rau domestic thiab txawv teb chaws kev lag luam tshiab ib tug centralized tso tawm.

Nyob rau hauv cov ntsiab lus, tam sim no caprolactam kev lag luam txhawb zog los ntawm tus nqi sab, caprolactam thiab PA6 polymerization muaj peev xwm siv tau nce synchronously, caprolactam mov thiab kev thov yog qhov sib npaug, nws xav tias caprolactam kev lag luam muaj zog nyob rau yav tom ntej. Lub hauv paus spinning teb yog qhov ruaj khov, thiab tsis muaj qhov hloov pauv tseem ceeb hauv cov khoom siv raw xav tau, thiab qhov kev kub ceev spinning teb tseem tuaj yeem ua raws. Cov pa hluav taws xob ua lag luam tseem qeeb los ua raws li, thiab nrog kev nce ntawm cov khoom siv thiab kev sib tw siab, tseem muaj kev tiv thaiv rau kev poob qis ntawm cov nqi siab. Nyob rau theem tom ntej, nws tseem yuav tsum tau them sai sai rau lub zog txuas ntxiv ntawm tus nqi nce thiab cov txheej txheem xa mus rau cov dej ntws.
