Kwikota yesithathu, uninzi lweemveliso ezikwishishini leacetone laseTshayina zibonise ukuguquguquka okunyukayo.Eyona nto iqhuba lo mkhwa kukusebenza ngamandla kwimakethi ye-oyile ekrwada yamazwe ngamazwe, nto leyo ethe yaqhuba intsingiselo eyomeleleyo yemarike yemathiriyeli ekrwada, ngakumbi ukonyuka okubonakalayo kwimarike ye-benzene emsulwa.Kule meko, icala leendleko ze-acetone industry chain lilawula ukunyuka kwexabiso, ngelixa imithombo yokungenisa i-acetone isanqongophele, ishishini le-phenol ketone linamazinga aphantsi okusebenza, kunye nokunikezelwa kwendawo kuqinile.Ezi zinto zidibene zixhasa ukusebenza ngamandla kwemarike.Ngeli xesha lekota, ixabiso eliphezulu le-acetone kwimarike ye-East China lalimalunga ne-7600 yuan ngetoni, ngelixa ixabiso eliphantsi laliyi-5250 yuan ngetoni nganye, kunye nokwahlukana kwexabiso le-2350 yuan phakathi kwesiphelo esiphezulu nesisezantsi.

Makhe sihlolisise izizathu zokuba kutheni imarike ye-acetone yasekhaya iqhubekile nokunyuka kwikota yesithathu.Ekuqaleni kukaJulayi, umgaqo-nkqubo wokurhafisa irhafu yokusetyenziswa kwezinye izinto zepetroli wagcina amaxabiso ezinto ezikrwada eqinile, kwaye ukusebenza kwe-benzene ecocekileyo kunye nepropylene nayo yomelele kakhulu.Iimarike ezisezantsi ze-bisphenol A kunye ne-isopropanol nazo ziye zafumana amaqondo ahlukeneyo okunyuka.Ngaphantsi kwendawo yonke efudumeleyo, imarike yasekhaya yeekhemikhali ibone ngokubanzi ukwanda.Ngenxa yomthwalo ophantsi we-650000 yeetoni ze-phenol ketone plant e-Jiangsu Ruiheng kunye nokubonelela okuqinileyo kwe-acetone, ababoneleli abaphethe iimpahla baye bawandisa kakhulu amaxabiso abo.Ezi zinto ziqhube ngokudibeneyo ukunyuka okunamandla kwemarike.Nangona kunjalo, ukususela ngo-Agasti, imfuno esezantsi iqale ukuba buthathaka, kwaye amashishini abonise iimpawu zobuthathaka ekuqhubeni amaxabiso, kwaye kukho umkhwa wokuyeka inzuzo.Nangona kunjalo, ngenxa yentengiso eyomeleleyo yebenzene esulungekileyo, iNingbo Taihua, iHuizhou Zhongxin, kunye neBluestar Harbin phenol ketone izityalo ziphantsi kogcino.I-Jiangsu Ruiheng ye-650000 yetoni ye-phenol ketone plant yayeka ngokungalindelekanga ngomhla we-18, eye yaba nefuthe elihle kwiimvakalelo zentengiso kunye nokuzimisela kwamashishini ukuyeka inzuzo akunamandla.Ngaphantsi kokudityaniswa kwezinto ezahlukeneyo, intengiso ibonakaliswa ikakhulu kukuguquguquka kwexesha.

Emva kokungena ngoSeptemba, imarike yaqhubeka isebenzisa amandla.Ukunyuka okuqhubekayo kwentengiso ye-oyile ekrwada yamazwe ngamazwe, intsingiselo eyomeleleyo yokusingqongileyo iyonke, kunye nokukhula kwemakethi ekrwada ecocekileyo ye-benzene kukhokelele ekonyukeni ngokubanzi kweemveliso zekhonkco leshishini le-phenolic ketone.Amandla aqhubekayo emarike ye-bisphenol A esezantsi iqhube imfuno efanelekileyo ye-acetone, kwaye ababoneleli abaphethe iimpahla bathathe eli thuba ukunyusa amaxabiso kunye nokuqhubela phambili ukukhula kweemarike.Ukongezelela, i-inventory ye-port ayiphezulu, kwaye izityalo ze-Wanhua Chemical kunye ne-Bluestar Phenol Ketone zigcinwa.Unikezelo lwamabala luqhubekile luqina, kunye nomlambo osezantsi ikakhulu ulandela imfuno.Ezi zinto ziye zaqhuba ngokudibeneyo ukunyuka kwamaxabiso emarike.Ekupheleni kwekota yesithathu, ixabiso lokuvala imarike ye-acetone yase-East China yayiyi-7500 yuan ngetoni, ukunyuka kwe-2275 yuan okanye i-43.54% xa kuthelekiswa nokuphela kwekota yangaphambili.

Nangona kunjalo, kulindeleke ukuba inzuzo eyongezelelweyo kwimarike ye-acetone e-East China inokuthintelwa kwikota yesine.Okwangoku, uluhlu lwamazibuko e-acetone luphantsi, kwaye unikezelo lulonke luqinile kancinci, ngamaxabiso aqinile.Nangona kunjalo, kunokuba nzima ukuba icala leendleko libe nokutyhala okunamandla kwakhona.Ngokukodwa emva kokungena kwikota yesine, ukuveliswa kweeyunithi ezintsha ze-phenolic ketone ziya kugxininiswa, kwaye ukunikezelwa kuya kwanda kakhulu.Nangona umda wengeniso yee-phenolic ketones ulungile, ngaphandle kwamashishini ahlala elungiswa rhoqo, amanye amashishini aya kugcina imveliso ephezulu yomthwalo.Nangona kunjalo, uninzi lweeyunithi ezintsha ze-phenolic ketone zixhotyiswe ngeeyunithi ezisezantsi ze-bisphenol A, ngoko ke ukuthengiswa kwangaphandle kwe-acetone ngamashishini asezantsi ayisebenzisayo kuncinci.Ngokubanzi, kulindeleke ukuba kwikota yokuqala yesine, imarike ye-acetone yasekhaya ingaguquguquka kwaye idibanise;Kodwa njengoko unikezelo lukhula, imarike inokujika ibe buthathaka kumanqanaba okugqibela.
