Ukusukela ngo-Agasti, ixabiso lasekhaya le-acetic acid sele likhula ngokuqhubekayo, ngexabiso eliphakathi lentengiso ye-2877 yuan / ton ekuqaleni kwenyanga enyuka ukuya kwi-3745 yuan / ton, inyanga ngenyanga yenyanga engama-30.17%. Ukunyuka kwamaxabiso evekini kuphinda unyuse inzuzo ye-acetic acid. Kuqikelelwa ukuba ingeniso ephakathi ye-acetic acid nge-21 ka-Agasti yayimalunga ne-1070 Yuan / Ton. Olu hlaselo lukwinzuzo "ye-Yuan Inzuzo" iphinde yaphakamisa amathandabuzo kwintengiso malunga nokuzinza kwamaxabiso aphezulu.
I-offream yemveli yexesha likaJulayi no-Agasti khange ibe nefuthe elibi kwintengiso. Ngokuchasene noko, ukuba nezinto zonikezo zidlale indima ekupheliseni imeko, ukuguqula i-Icetic ye-Acetic elawula imakethi ye-acetic ye-acid kwimfuno elawulwa ngenkalo yoncedo.

Iqondo lokusebenza lezityalo ze-acetic ze-acetic inciphile, ixhamla intengiso
Ukusukela ngoJuni, izixhobo zangaphakathi ze-acetic acid zicwangciselwe isondlo, ezikhokelela ekunciphiseni kwenqanaba lokusebenza ukuya kuthi ga kwi-67%. Umthamo wokuvelisa kwezi sixhobo solondolozo sikhulu, kwaye ixesha lokulungisa lide kakhulu. Uluhlu lweshishini ngalinye luyaqhubeka nokwehla, kwaye inqanaba le-inventri iphela likwinqanaba eliphantsi. Ekuqaleni, kwakucingelwa ukuba izixhobo zesondlo ziya kuphinda zibuyele kancinci ngoJulayi, kodwa inkqubela phambili yokubuyisela yesixhobo ayikafiki ngokupheleleyo, kunye neendlela eziqhubekayo zokuqala kunye nokuma, iziphumo zezinto zexesha elide ezinokwenzeka Ungathengiswa ngobungakanani ngoJuni kwakhona ngoJulayi, kwaye uluhlu lwentengiso lwentengiso luyaqhubeka luhlala luphantsi.

Ukufika kuka-Agasti, izixhobo eziphambili zesondlo sokuqala sihlaziya ngokuthe ngcembe. Nangona kunjalo, ubushushu obucokisekileyo bubangele ukusilela rhoqo kwezixhobo kwabanye abavelisi, kunye neemeko zokugcina kunye neyenzekile zenzekile ngendlela egxile. Ngenxa yezi zizathu, inqanaba lokusebenza le-acetic acid ayikafiki kwinqanaba eliphezulu. Emva kokuqokelelwa kwesondlo kwiinyanga ezimbini zokuqala, bekukho ukunqongophala kweempahla kwintengiso, kukhokelela kwiimeko ezingaphezulu kwamashishini ahlukeneyo ngo-Agasti. Indawo yentengiso yayiqinile kakhulu, kwaye amaxabiso anyukele kwincopho yabo. Ukusukela kule meko, inokubonwa ukuba ukunqongophala kwendawo ngo-Agasti kwakungenzi nto ngaphandle kwesigqibo sexesha elincinci, kodwa endaweni yokuqokelelwa kwexesha elide. Ukusukela ngoJuni ukuya kuJulayi, amashishini ahlukeneyo alawula ngokufanelekileyo icala lokuhambisa ngokugcina nokugcina ingxaki, ukugcina uluhlu oluzinzileyo oluzinzileyo lwe-acetic acid. Kungathi oku kunikezwe iimeko ezifanelekileyo zokwanda kwamaxabiso e-acetic acid ngo-Agasti.
I-2. I-Dowream Fune iphucuka, inceda i-Acetic Acid Acid inyuke
Ngo-Agasti, inqanaba lokusebenza eliphakathi lokusebenza kwe-pirestream ye-acid downkhaam yayimalunga ne-58%, ukunyuka kwe-3.67% ethelekiswa ne-Julayi. Oku kubonisa ukuphucuka okuncinci kwimfuno ye-Dowream yasekhaya. Nangona ireyithi yokusebenza yenyanga ayikadlulanga i-60%, ukuqalisa kwakhona kwemveliso yeemveliso ezithile kunye nezixhobo kunefuthe elifanelekileyo kwintengiso yengingqi. Umzekelo, umyinge ophakathi wokusebenza kwe-vinyl ye-vinyl yenziwa nge-18.61% ngo-Agasti. Ifowuni iqala kwakhona kule nyanga igxile ikakhulu kumda ntshona, okukhokelela kunikezelo oluqinileyo kunye nemozulu eyonyukayo yamaxabiso onyuka kuloo mmandla. Ngeli xesha, inqanaba lokusebenza le-PTA lisondele kwi-80%. Nangona i-PTA inefuthe elincinci kwixabiso le-acetic acid, ireyithi yokusebenza yayo ibonakalisa ngqo inani le-acetic acid esetyenzisiweyo. Njengomntu ophambili kwimakethi esezantsi eMpuma China, iqondo lokusebenza likaPTA likwanempembelelo entle kwimakethi ye-acetic acid.
Uhlalutyo lweMatriki
Ulungiso loMvelisi: Okwangoku, uluhlu lwamashishini ahlukeneyo lugcinwa kwinqanaba eliphantsi, kwaye imakethi ijonge ukubonelela ngendawo eqinileyo. Amashishini anomdla kakhulu kuguquko lwe-inventri, kwaye emva kokuba uluhlu lwezinto luqokelela, kunokubakho enye imeko yokungasebenzi kakuhle kunye nokumelwa kwemveliso. Ngaphambi kokuba i-inventri iqokelelene, icala lokuhambisa lihlala lizinza, kwaye uhlengahlengiso olucwangcisiweyo "oluncinci" lunokuba nefuthe elihle lokwahlula kwintengiso kwakhona. Kulindelwe ukuba nge-25 ka-Agasti, kuya kubakho izicwangciso zesondlo kwizixhobo eziphambili kwingingqi ye-AHui, enokuthi igqithe ngexesha lesondlo sexesha elifutshane lesixhobo se-nanjing, ngelixa kungekho zicwangciso ziqhelekileyo zokulungisa ezibhengeziweyo kwezinye iindawo. Kule meko, kuyimfuneko ngakumbi ekujonganeni ngokusondeleyo ukubek 'phambili ukuguquguquka kwi-inventri yeshishini ngalinye kunye nokuba kunokwenzeka ukusilela kwesiquphe.
I-Dowystream Ibango: Okwangoku, uluhlu lwe-Acetic acid acid lusenokulawulwa, kwaye iifektri ezihamba ezantsi zigcinwa okwethutyana kwimvumelwano okwethutyana ngemvumelwano yexesha elide. Nangona kunjalo, ukunyuka okukhawulezayo kumaxabiso e-Acid anyukayo kwenza ukuba kube nzima ukwenza amaxabiso emveliso edolophini ukudlulisela ngokupheleleyo kwimfuno yentengiso. Amanye amashishini amakhulu aphantsi ajongene noxinzelelo lwenzuzo. Okwangoku, phakathi kweemveliso eziphambili ze-acetic ze-acetic acid, ngaphandle kwe-methyl acetate kunye ne-N-Propyl Ester, ingeniso yezinye iimveliso ziphantse zahamba ngomgca weendleko. Inzuzo ye-vinyl acetate (eveliswa yindlela ye-calcium caltide), i-PTA, kunye ne-butyl i-acetate ikwabonisa into engaguqukiyo. Ke ngoko, amashishini ambalwa athathile amanyathelo okunciphisa umthwalo wabo okanye ukumisa.

Imizi-mveliso ye-Dowream ijonge nokubona amaxabiso anokubonakala kwiinzuzo zesiphelo sendlela. Ukuba inzuzo yemveliso esezantsi yokwehla iyancipha ngelixa ixabiso le-acetic acid lihlala liphezulu, kulindeleke ukuba ukuveliswa kwemveliso edolophini kunokuqhubeka nokunciphisa imeko yenzuzo.

Umthamo omtsha wemveliso: Kulindelwe ukuba ukuphela kukaSeptemba nangexesha lika-Okthobha, kuya kubakho inani elikhulu lemveliso entsha ye-vinyl acetate, itotali malunga neetoni ezingama-30000 malunga neetoni ezitsha zemveliso, kwaye kulindeleke ukuba zisebenzise iitoni ezingama-270000 ze i-acetic acid. Kwangelo xesha, kulindeleke ukuba amandla okutsha kwemveliso ye-caprolactam aya kufikelela kwiitoni ezingama-300000, eza kuthatha iitoni ezingama-240000 ze-acetic acid. Kuyaqondakala ukuba izixhobo ezihamba ezantsi kulindeleke ukuba zibhale kufuneka zisebenze zinokuqalisa ukuveliswa kwe-acetic acid phakathi kweSeptemba. Ngenxa yendawo yendawo eqinileyo ye-ACOT kwimakethi ye-acetic, ukuveliswa kwezi zixhobo zintsha kubophelelekile ukubonelela ngenkxaso elungileyo kwimakethi ye-acetic acid kwakhona.

Ngexesha elifutshane, ixabiso le-acetic acid isazigcina ixesha eliphezulu, kodwa ukwanda kakhulu kumaxabiso e-acetic kwiveki ephelileyo kwabangela ukumelana nokusebenza kwabavelisi be-Dowream, okhokelayo ekuthengweni kwenzondelelo. Okwangoku, kukho i-foam eyogqithisileyo "kwi-foam" kwimakethi ye-acetic acid, ke ixabiso linokuwa kancinci. Ngokuphathelele imeko yentengiso ngoSeptemba, kusafuneka ukuba abekekeke ngokusondeleyo ixesha lemveliso le-Acetic ye-ACCIC. Okwangoku, uluhlu lwe-acetic acid luphantsi kwaye lungagcinwa kude kube ekuqaleni ngoSeptemba. Ukuba isikhundla esitsha semveliso asibekwanga ntsebenziso njengoko sicwangcisiwe ngaphambi kokuphela kukaSeptemba, ezantsi komgangatho omtsha wemveliso inokuthengwa nge-acetic acid kwangaphambili. Ke ngoko, sihlala sinethemba malunga nendawo yentengiso ngoSeptemba kwaye kufuneka igcine iliso kwimiba ethile yemakethi ye-Optisam kunye neemakethi ezantsi, ibeka esweni utshintsho lwexesha lokwenyani kwimarike.
