Bisphenol A:
Pankhani ya mtengo: Pambuyo pa tchuthi, msika wa bisphenol A unali wofooka komanso wosasunthika. Pofika pa Meyi 6, mtengo wa bisphenol A ku East China unali 10000 yuan/ton, kutsika ndi 100 yuan poyerekeza ndi tchuthi chisanachitike.
Pakali pano, msika wa kumtunda kwa phenolic ketone wa bisphenol A umasinthasintha mkati mwa njira yopapatiza, ndipo mayunitsi a carbon polymerization a Cangzhou Dahua ndi Yanhua akukonzedwabe, ndipo sipanakhale kusintha kwakukulu kumbali yogulitsa bisphenol A. Msika wonse ndi mitengo ndi yofooka.
Pankhani ya zopangira, msika wa phenolic ketone unasinthasintha pang'ono sabata yatha: mtengo waposachedwa wa acetone unali 6400 yuan/tani, ndipo mtengo waposachedwa wa phenol unali 7500 yuan/ton, zomwe zinawonetsa kusinthasintha pang'ono poyerekeza ndi tchuthi chisanachitike.
Chipangizo zinthu: Huizhou Zhongxin 40000 tani chipangizo, Cangzhou Dahua 200000 tani chipangizo shutdown, Yanhua Mpweya Kusonkhanitsa 150000 tani chipangizo shutdown yokonza yaitali yokonza; Chiwopsezo chonse chamakampani ndi pafupifupi 70%.
Epichlorohydrin:
Pankhani ya mtengo: Msika wa epichlorohydrin unatsika pang'ono pambuyo pa tchuthi: kuyambira pa Meyi 6, mtengo wa epichlorohydrin kumsika waku East China unali 8600 yuan/ton, kutsika kwa yuan 300 poyerekeza ndi tchuthi chisanachitike.
Misika yapakatikati ya propylene ndi chlorine yamadzimadzi ikuwonetsa kutsika, pomwe mitengo ya glycerol imakhalabe yotsika komanso kuthandizira kwamtengo kumakhala kofooka. Chikondwererocho chisanachitike, mafakitale akumunsi a epoxy resin adawonetsa chidwi chochepa pogula epichlorohydrin. Chikondwererochi chitatha, msika unayamba kuchepa kwambiri, ndipo katundu wa fakitaleyo sanali wosalala. Zotsatira zake, kukambirana pamitengo pang'onopang'ono kunasunthira pansi.
Pankhani ya zopangira, panali kuchepa pang'ono kwa mitengo ya ECH zida zazikulu zopangira njira ziwiri zopangira mkati mwa sabata: mtengo waposachedwa wa propylene unali 7100 yuan / tani, kuchepa kwa 200 yuan poyerekeza ndi tchuthi chisanachitike; Mtengo waposachedwa wa 99.5% glycerol ku East China ndi 4750 yuan/ton, womwe sunasinthe kuyambira tchuthi chisanachitike.
Mkhalidwe wa chipangizo: Zida zambiri monga Wudi Xinyue, Jiangsu Haixing, ndi Shandong Minji zili ndi katundu wochepa; Chiwerengero chonse cha ntchito zamakampani ndi pafupifupi 60%.
epoxy utomoni:
Pankhani ya mtengo: Sabata yatha, mitengo yapakhomo ya epoxy resin idakhalabe yokhazikika: kuyambira pa Meyi 6, mtengo wamafuta a epoxy resin ku East China unali 14600 yuan/ton (Fakitale ya East China/mbiya), ndipo mtengo wowerengera wa epoxy resin wolimba unali 13900 yuan/ton (mtengo wotumizira ku East China).
Pakangotha ​​​​masiku ochepa ogwira ntchito pambuyo pa tchuthi, unyolo wa epoxy resin umakhala ndi kusinthasintha kofooka. Pambuyo pa tchuthi chisanadze kutsika masitonkeni ndi kubwera kwa mgwirizano m'zinthu zatsopano kumayambiriro kwa mwezi, kumwa kwa zipangizo kumatengera mapangano ndi kufufuza, ndipo chidwi cholowa mumsika wogula sichikwanira. Zopangira bisphenol A ndi epichlorohydrin zikuwonetsa kutsika, makamaka pamsika wa epichlorohydrin. Kumbali ya mtengo, pali kutsika, koma kumayambiriro kwa mwezi, opanga epoxy resin nthawi zambiri amafotokoza mitengo yokhazikika. Komabe, ngati zopangira ziwirizi zikupitirirabe kutsika sabata yamawa, msika wa epoxy resin udzatsikanso moyenerera, ndipo msika wonse umakhala wofooka.
Pankhani ya zida, kuchuluka kwa magwiridwe antchito a utomoni wamadzimadzi ndi pafupifupi 70%, pomwe kuchuluka kwa utomoni wokhazikika ndi pafupifupi 50% Kugwira ntchito kwa utomoni wamadzimadzi kumakhala pafupifupi 70%, pomwe ntchito yonse ya utomoni wokhazikika ndi pafupifupi 50%.
