Kev Taw Qhia: Kev lag luam benzene ntshiab tsis ntev los no txuas ntxiv nce siab, thiab sab nqi tsim kev txhawb nqa zoo rau kev lag luam caprolactam, thiab kev lag luam caprolactam ua raws li kev nce siab. Lub zog txhawb nqa tseem ceeb ntawm kev lag luam lig tseem yog los ntawm sab nqi, nws xav tias kev lag luam caprolactam yuav khiav zoo heev yav tom ntej, thiab lub zog txuas ntxiv ntawm kev nce nqi thiab cov txheej txheem xa mus rau theem tom qab yuav txhawj xeeb.

Txij li thaum Lub Xya Hli, kev lag luam benzene ntshiab tau txhawb nqa los ntawm ntau yam xws li kev nce hauv roj av nyoos, kev txhim kho ntawm nws tus kheej cov qauv kev muab khoom thiab kev thov thiab kev cuam tshuam ntawm cov xov xwm ntsig txog se siv rau kev thov ethylbenzene, thiab kev lag luam benzene ntshiab tau txuas ntxiv nce. Sinopec pure benzene teev tus nqi txij li thaum pib ntawm lub hlis 6200 yuan / ton nce mus rau 6950 yuan / ton tam sim no.

Tus nqi ntawm cov benzene ntshiab tseem nce ntxiv, tus nqi ntawm cov lag luam caprolactam tau nce ntxiv, thiab tus nqi ntawm cov khoom tau nce ntxiv. Tam sim no, tus nqi ntawm caprolactam hauv Sab Hnub Tuaj Suav teb tau nce mus txog ze li ntawm 12300 yuan / ton, thiab qee qhov kev xa khoom caprolactam hauv sab qaum teb nruj me ntsis, thiab kev txaus siab rau kev yuav khoom hauv qab yog OK hauv cov txheej txheem nce mus, thiab lub Hoobkas polymerization feem ntau ua raws li qhov xav tau.

Tom qab rov pib dua ntawm Luxi Chemical Industry, Cangzhou Xuyang Theem I thiab lwm yam khoom siv, kev siv caprolactam muaj peev xwm nce mus txog 81.35%, tsuas yog qee cov khoom siv nres tsheb ntev tseem nyob hauv lub xeev nres tsheb, lwm cov khoom siv yeej khiav li qub. Txawm li cas los xij, vim tias cov khoom muag caprolactam tsawg thaum ntxov, ua ke nrog kev ua lag luam tam sim no nyob rau hauv kev nce siab, thiab kev nyiam yuav khoom hauv qab, sab qaum teb ntawm cov khoom siv tseem nruj me ntsis.

PA6 polymerization peev xwm siv tus nqi tsis ntev los no tau nce synchronously, ntawm ib sab tes, qhov kev nyiam ntawm kev kub ceev spinning downstream txuas ntxiv txhawb nqa qhov pib ntawm polymerization, ntawm qhov tod tes, lub cuab yeej nres tsheb thaum ntxov ntawm Luxi Chemical tau maj mam rov pib dua, thiab PA6 peev xwm siv tus nqi tau nce mus txog ze li ntawm 76%, thiab cov zis slicing txhua lub lim tiam thiab caprolactam txhua lub lim tiam tau nce synchronously mus txog ze li ntawm 100,000 tons.

Cov nylon filament load downstream tseem ruaj khov, thiab qhov nruab nrab hauv tebchaws tam sim no nylon filament load yog li 79.5%. Tus nqi ua haujlwm tag nrho ntawm cov tshuaj fiber weaving hauv Jiangsu thiab Zhejiang cheeb tsam yog 63.47%, poob qis 0.40% los ntawm lub lim tiam dhau los. Weaving pib poob me ntsis, tab sis qhov kev hloov pauv tag nrho yog me ntsis, tam sim no terminal weaving tsis cuam tshuam los ntawm kev faib hluav taws xob, cov neeg siv downstream feem ntau nyob rau theem tos thiab tos-thiab-saib, tos kev lag luam hauv tebchaws thiab txawv teb chaws tshiab ib qho kev tso tawm hauv nruab nrab.

Hauv kev xaus lus, lub zog txhawb nqa kev lag luam caprolactam tam sim no los ntawm sab nqi, caprolactam thiab PA6 polymerization peev xwm siv tus nqi nce synchronously, caprolactam kev muab khoom thiab kev thov yog qhov sib npaug, nws xav tias kev lag luam caprolactam yuav muaj zog yav tom ntej. Lub tshav pob spinning downstream yog qhov ruaj khov, thiab tsis muaj kev hloov pauv tseem ceeb hauv kev cia siab ntawm cov khoom siv raw, thiab lub tshav pob spinning ceev tseem tuaj yeem ua raws li. Lub tshav pob textile ib txwm tseem qeeb ua raws li, thiab nrog kev nce ntawm kev muab khoom thiab kev sib tw siab, tseem muaj kev tiv thaiv rau kev xa mus rau hauv qab ntawm cov nqi siab. Hauv theem tom qab, nws tseem tsim nyog yuav tsum tau them sai sai rau lub zog txuas ntxiv ntawm kev nce nqi thiab cov txheej txheem xa mus rau downstream.
