Ngesonto eledlule, imakethe ye-epoxy resin yayibuthakathaka, futhi amanani embonini awela ngokungapheli, okwakuvame ukuba yi-bearish. Ngesonto, i-bisphenol A eluhlaza yayisebenza ezingeni eliphansi, futhi enye impahla eluhlaza, i-epichlorohydrin, iguquguquka yehle ngebanga elincane. Izindleko zempahla eluhlaza zenza buthaka ukusekelwa kwayo kwezimpahla ezikhona. Izinto zokusetshenziswa ezikabili ziqhubekile nokwehla ngendlela ebuthakathaka, futhi isidingo semakethe ye-resin asizange sibe ngcono. Izinto eziningi ezimbi ziholele ekungakwazini ukuthola isizathu esihle sentengo ye-epoxy resin. Izingcaphuno zomkhiqizo wesigaba sesibili nesesithathu ze-LER emakethe zilethwe ngo-15800 yuan/ton. Izintengo zabakhiqizi abakhulu abajwayelekile behlele ezingeni eliphansi kakhulu kulo nyaka, futhi kusekhona okulindelekile ukuncishiswa kwentengo.
Ngesonto eledlule, imboni enkulu eJiangsu yama ukuze ilungiswe, futhi umthwalo wezinye izitshalo washintsha kancane. Umthwalo oqalayo usuwonke wehlile uma uqhathaniswa nesonto eledlule. Phakathi nesonto, isidingo esingaphansi komfula sasintekenteke, futhi umoya wama-oda amasha wawulula. NgoLwesithathu olwedlule kuphela, isimo sokubuza nokugcwaliswa sathuthukiswa kancane, kodwa sasibuswa ukugcwaliswa okudingekayo nje. Ingcindezi kubakhiqizi beresin ukuthi bathumele iphezulu, futhi ezinye izimboni zizwa ukuthi inani lempahla liphezulu kancane. Kukhona i-margin eningi kulokho okunikezwayo, futhi ukugxila ekuhwebeni kwemakethe kuphansi.
I-Bisphenol A: Ngesonto eledlule, izinga lokusebenzisa amandla ezitshalo zasekhaya ze-bisphenol A lalingu-62.27%, lehle ngamaphesenti angu-6.57 kusukela ngoNovemba 3. Kuleli sonto lokuvalwa nokugcinwa kwepulasitiki eSouth Asia, iNantong Star Bisphenol A Plant ihlelelwe ukuvalwa ukuze ilungiswe. isonto elilodwa ngoNovemba 7, kanti iChangchun Chemical Industry ihlelelwe ukuvalwa ukuze kulungiswe imigqa emibili (umugqa wokuqala kuvalwe ngenxa yokwehluleka ngoNovemba 6, okulindeleke ukuthi kube yisonto elilodwa). I-Huizhou Zhongxin ivalwa okwesikhashana izinsuku ezi-3-4, futhi akukho ukushintshashintsha okusobala emthwalweni wamanye amayunithi. Ngakho-ke, izinga lokusebenzisa umthamo wesitshalo sasekhaya se-bisphenol A liyehla.
I-Epichlorohydrin: Ngesonto eledlule, izinga lokusebenzisa amandla embonini yasekhaya ye-epichlorohydrin lalingu-61.58%, likhuphuke ngo-1.98%. Ngesonto, i-Dongying Liancheng 30000 t/a isitshalo se-propylene yavalwa ngo-Okthoba 26. Njengamanje, i-chloropropene iwumkhiqizo oyinhloko, futhi i-epichlorohydrin ayikaqaliswa kabusha, futhi isendleleni yokulandelela; Ukukhishwa kwansuku zonke kwe-epichlorohydrin ye-Binhua Group kukhuphuke kwafinyelela kumathani angu-125 ukulinganisa i-hydrogen chloride ekhuphuka nomfula; I-Ningbo Zhenyang 40000 t/a glycerol process plant yaqalwa kabusha ngoNovemba 2, futhi okukhiphayo kwansuku zonke kwamanje kungamathani ayi-100; U-Dongying Hebang, u-Hebei Jiaao kanye no-Hebei Zhuotai basesesimweni sokupaka, futhi isikhathi sokuqalisa kabusha siyalandela; Ukusebenza kwamanye amabhizinisi kunoshintsho oluncane.
Isibikezelo semakethe esizayo
I-Bisphenol Inzuzo yemakethe ikhule kancane ngempelasonto, futhi izimboni ezansi nomfula zaziqaphe kakhulu ekungeneni emakethe. Abahlaziyi bezimakethe bakholelwa ukuthi: isimo sengqondo sabathengi nabathengisi sizoqhubeka nokudlala imidlalo ngesonto elizayo, ngezinguquko ezilinganiselwe ezintweni eziyisisekelo zesikhashana. Ukulindela okubuthakathaka okulethwa idivayisi entsha kuzocindezela ukucabanga kwemakethe, futhi imakethe kulindeleke ukuthi ilungise umugqa wezindleko.
I-cyclide chloride iqhubekile nokugijima. Izibalo eziphezulu zenhlalo kanye namahemuhemu okuthi amayunithi aphindwe kabili eNyakatho neNingizimu azofakwa ekukhiqizweni ngenyanga ezayo kwenze abantu basemakethe baqapha futhi nesimo sokulinda nokubona emakethe sahlala singashintshile. Ngokusho kokuhlaziywa kwabangaphakathi, nakuba imakethe yamanje izinzile okwesikhashana, kungenzeka ukuthi imakethe yesikhathi esizayo izoqhubeka nokwehla.
Ukunikezwa kwemakethe ye-LER akugcini nje ngokukhiqiza okukhulayo kwemishini yokulungisa, kodwa futhi kunamandla amasha angena emakethe. Kuyaqondakala ukuthi isitshalo se-epoxy eWuzhong, Zhejiang (Shanghai Yuanbang No.2 Factory) sifakwe ngempumelelo esivivinyweni ezinsukwini ezimbalwa ezedlule. Ngemuva kweqoqo lesibili, umbala womkhiqizo usufinyelele cishe ku-15 #. Uma uqhubeka uzinzile esikhathini esizayo, umkhiqizo ngeke ungene emakethe isikhathi eside. I-LER izoqhubeka nokushayela emuva okubuthakathaka, ngesidingo ikakhulukazi sokuthenga okuqinile, futhi kunzima ukubona izimpawu zokululama esikhathini esifushane.
