Sabata ino, likulu lamitengo yazinthu zamafakitale a phenol-ketone nthawi zambiri zidatsika. Kutsika kwamitengo yotsika, kuphatikizika ndi kukakamizidwa kwa kaphatikizidwe ndi kufunikira, zidapangitsa kutsika kwamitengo yamakampani. Komabe, zogulitsa zam'mwamba zimawonetsa kukana kwakukulu poyerekeza ndi zotsika, zomwe zidapangitsa kuchepa kwa phindu m'mafakitale akumunsi. Ngakhale kuti kutayika kwapakati pa mafakitale a phenol-ketone kunachepa, phindu lonse lazinthu zakumtunda ndi zapakati zimakhalabe zofooka, pamene kumunsi kwa MMA (Methyl Methacrylate) ndi mafakitale a isopropanol adasungabe phindu linalake.
Pankhani ya mitengo pafupifupi mlungu uliwonse, kupatulapo kuwonjezeka pang'ono pa mlungu pafupifupi mtengo wa phenol (chinthu wapakatikati), zinthu zina zonse mu phenol-ketone mafakitale unyolo analemba kutsika, ndi ambiri kugwa mu osiyanasiyana 0.05% kuti 2.41%. Pakati pawo, zinthu zakumtunda benzene ndi propylene zonse zidafooka, mitengo yawo yapakati pa sabata imatsika ndi 0.93% ndi 0.95% mwezi ndi mwezi motsatana. Pakati pa sabata, pambuyo pokwera pang'ono motsatizana, mitengo yamafuta amafuta am'tsogolo idatsika kwakanthawi kochepa. Kumapeto kwa msika kunakhalabe kwaulesi, ndipo malingaliro osamala otsika anali amphamvu. Komabe, kufunikira kophatikiza mafuta a petulo ku US kudakwezera mitengo ya toluene, ndipo magawo osagwirizana adatsekedwa chifukwa chakusokonekera kwachuma, zomwe zidapangitsa kuti mitengo ya benzene ibwerenso kumapeto kwa sabata. Pakadali pano, mayunitsi ena otsika a propylene adayambiranso kugwira ntchito, kukulitsa pang'ono thandizo la propylene. Ponseponse, ngakhale kutha kwazinthu zopangira zidawonetsa kufowoka, kutsika kwake kunali kocheperako kuposa zomwe zidatsika pansi.
Zogulitsa zapakatikati phenol ndi acetone nthawi zambiri zimagulitsidwa cham'mbali, ndikusinthasintha pang'ono pakusintha kwamitengo yawo yapakati pamlungu. Ngakhale kuti mtengo wake unali wotsika mtengo, mayunitsi ena akumunsi a bisphenol A anayambiranso kugwira ntchito, ndipo panali kuyembekezera kukonzanso mayunitsi a Hengli Petrochemical a phenol-ketone panthawi yamtsogolo. Zinthu zazitali komanso zazifupi zimalumikizana pamsika, zomwe zimapangitsa kuti pakhale kusamvana pakati pa ogula ndi ogulitsa. Zogulitsa zam'munsi zidatsika kwambiri kuposa kutha kwa mtengo wake chifukwa cha kupezeka kokwanira komanso kuchepa kwa zomwe zimafunikira. Sabata ino, mtengo wapakati pa sabata wamakampani otsika a MMA adatsika ndi 2.41% mwezi-pa-mwezi, kutsika kwakukulu kwa sabata pamakina ogulitsa mafakitale. Izi zidachitika makamaka chifukwa chakusokonekera kocheperako, zomwe zidapangitsa kuti msika uzikhala wokwanira. Makamaka, mafakitale opangidwa ku Shandong adakumana ndi vuto lalikulu lazinthu ndipo adayenera kutsitsa mawu kuti alimbikitse kutumiza. Makampani akumunsi a bisphenol A ndi isopropanol adakumananso ndi zinthu zina zotsikirapo, pomwe mitengo yapakati pa sabata yatsika ndi 2.03% ndi 1.06% motsatana, popeza msika udakhalabe pakusintha kwapang'onopang'ono kofooka pakati pa kupezeka ndi kukakamizidwa kofunikira.
Ponena za phindu lamakampani, mkati mwa sabata, zomwe zidakhudzidwa ndi kuchuluka kwa kuchuluka kwa chakudya komanso kuchuluka kwa kufunikira m'mafakitale akumunsi komanso kutsika mtengo kwapang'onopang'ono, kupindula kwa zinthu zomwe zili m'munsi mwazinthu zamafakitale zikuwonetsa kutsika. Ngakhale kuti kutayika kwa msika wapakati pa phenol-ketone kunakula bwino, phindu lonse lachidziwitso la makina opanga mafakitale linatsika kwambiri, ndipo zinthu zambiri zomwe zili muzitsulozo zinakhalabe zotayika, zomwe zimasonyeza kufooka kwa malonda a mafakitale. Pakati pawo, mafakitale a phenol-ketone adalemba kuwonjezeka kwakukulu kwa phindu: kutayika kwachidziwitso kwa mafakitale sabata ino kunali 357 yuan / tani, kuchepetsa ndi 79 yuan / tani poyerekeza ndi sabata yatha. Kuonjezera apo, phindu la makampani otsika a MMA adatsika kwambiri, ndi phindu la mlungu uliwonse lazamalonda pa 92 yuan / tani, kuchepa kwa 333 yuan / tani kuyambira sabata yatha. Ponseponse, phindu lomwe lilipo pamakampani a phenol-ketone ndi lofooka, ndipo zinthu zambiri zikadali zotayika. Ndi mafakitale okhawo a MMA ndi isopropanol omwe ali ndi phindu lamalingaliro pang'ono kuposa mzere wopuma.
Kuyikira Kwambiri: 1. M'kanthawi kochepa, mitengo yamafuta amafuta am'tsogolo ikhoza kukhala yosasunthika komanso yofooka, ndipo ndalama zofooka zikuyembekezeka kupitilizabe kutsika. 2. Kupanikizika kwa makampani opanga mafakitale kumakhalabe, koma mitengo yazinthu zamafakitale imakhala yotsika kwazaka zambiri, kotero kuti malo otsika mtengo angakhale ochepa. 3. Ndizovuta kuti mafakitale ogwiritsira ntchito mapeto awone kusintha kwakukulu, ndipo kufunikira kofooka kungapitirire kupereka ndemanga zoipa kumtunda.
