Nhanganyaya: Iyo ichangoburwa yekumusoro yakachena benzene musika inoramba ichikwira, uye mutengo wedivi unoumba rutsigiro rwakasimba kumusika wecaprolactam, uye musika wecaprolactam unotevera maitiro ekukwira. Simba guru rinotsigira remusika wekupedzisira richiri kubva kudivi remutengo, zvinotarisirwa kuti musika we caprolactam uchamhanya zvakasimba munguva pfupi iri kutevera, uye simba rinoramba riripo rekukwira kwemitengo uye nzira yekufambisa yepasi ichave iine hanya munguva inotevera.

Kubva munaChikunguru, misika yebenzene yakachena yakakwidziridzwa nezvinhu zvakati wandei zvakaita sekukwira kwemafuta asina kukora, kuvandudzwa kwekupihwa kwayo uye maitiro ekuda uye mabatiro enhau dzine chekuita nemutero wemutero pakudiwa kweethylbenzene, uye musika webenzene wakaramba uchiita. simuka. Sinopec pure benzene yakanyorwa mutengo kubva pakutanga kwemwedzi 6200 yuan/ton yakakwira kusvika pa6950 yuan/ton iripo.

Mutengo weiyo benzene yakachena unoramba uchikwira, mutengo wecaprolactam mabhizinesi wakawedzera, uye mutengo wezvigadzirwa wakakwira. Parizvino, mutengo wecaprolactam kuEast China wakwira kusvika padyo ne12300 yuan/tani, uye zvimwe zvinotakura caprolactam kuchamhembe zvakati twii, uye kufarira kwekutenga zvinhu kwakadzika kwakanaka mukukwira kumusoro, uye fekitori yepolymerization inoteedzera. sezvinodiwa.

Nekutangazve kweLuxi Chemical Indasitiri, Cangzhou Xuyang Phase I nemimwe michina, chiyero chekushandiswa kwecaprolactam chakawedzera kusvika pa81.35%, kunze kwekunge zvimwe zvigadziriso zvenguva refu zvekupaka zvichiri munzvimbo yekupaka, mamwe maturusi ari kushanda sezvakajairika. Nekudaro, nekuda kweiyo yakaderera hesiti ye caprolactam mukutanga nhanho, pamwe nemusika wazvino uri mukukwira kumusoro, uye kudzika kwakadzika kwekutenga kwechido kufarira, chikamu chekuchamhembe chekugovera chichiri kusimba zvishoma.

PA6 polymerization simba rekushandisa chiyero ichangobva kukwira synchronously, kune rimwe divi, kudiwa kwekuda kweyakakwira-kumhanya kutenderera kuzasi kunoramba kuchitsigira kutanga kwepolymerization, kune rimwe divi, yekutanga kupaka mota yeLuxi Chemical yakatanga zvishoma nezvishoma, uye iyo PA6 huwandu hwekushandisa huwandu hwawedzera kusvika padyo ne76%, uye vhiki nevhiki slicing kubuda uye caprolactam vhiki nevhiki kubuda kwakawedzera synchronously kusvika pedyo ne100,000 matani.

Iyo yakadzika naironi filament mutoro inoramba yakagadzikana, uye ikozvino mudzimba avhareji yenylon filament mutoro ingangoita 79.5%. Huwandu hwekushanda hwemakemikari fiber weaving mudunhu reJiangsu neZhejiang hwaive 63.47%, pasi ne0.40% kubva svondo rapfuura. Kuruka kwakatanga kuderera kudiki, asi kuchinja kwese kudiki, iko zvino kuruka kuruka hakukanganiswe nemagetsi emagetsi, vashandisi vepasi vari kunyanya mukumirira uye kumirira-uye-kuona nhanho, vakamirira kutengeserana kwemumba nekune dzimwe nyika itsva imwe yepakati kusunungurwa.

Muchidimbu, iyo yazvino caprolactam musika wekutsigira simba rinobva kudivi remutengo, caprolactam uye PA6 polymerization simba rekushandisa chiyero chakawedzera synchronously, caprolactam kupihwa uye kudiwa kwakanyatso kuenzana, zvinotarisirwa kuti musika wecaprolactam wakasimba munguva pfupi iri kutevera. Munda wekutenderera wakadzika wakadzikama, uye hapana shanduko yakakosha mukutarisira kudiwa kwezvinhu, uye iyo yekumhanya-mhanya inotenderera ichiri kukwanisa kutevera. Iyo yakajairwa machira munda ichiri kunonoka kutevera, uye nekuwedzera kwekupa uye kukwikwidza kumanikidza, kuchine kuramba kuderera kutapurirana kwemitengo yakakwira. Muchikamu chekupedzisira, zvichiri kufanira kubhadhara kune simba rinoramba riripo rekuwedzera kwemutengo uye nzira yekuendesa kune yakadzika.
