Kusukela ngasekupheleni kuka-Ephreli, imakethe ye-epoxy e-Epoxy e-Epoxy iphinde yaphinde yathabatha umkhuba wokuhlanganiswa kwezikhathi ezithile, ngesimo sokuhweba se-lukawarm kanye nomdlalo oqhubekayo wokuthola izimpahla emakethe.

Side Side: I-Zhenhai Refining kanye nesitshalo samakhemikhali e-East China asikaqalisise kabusha, futhi isitshalo se-petroclemite se-petrochemical sesivaliwe ukuqeda ukushoda. Ukusebenza kwezinsiza zeSpool emakethe yase-East China kungaqina kancane. Kodwa-ke, ukuhanjiswa emakethe yasenyakatho kuningi, futhi amabhizinisi okukhiqiza ngokuvamile athumela izimpahla, okuholela ekuqongeleleni okuncane kokusungula; Ngokuya kwezinto ezisetshenziswayo, imakethe ye-propenene iye yaphela, kepha njengamanje amanani ahlala ephansi. Ngemuva cishe kwesonto le-stalemate, imakethe ye-chlorine ewuketshezi iwele ngaphansi kwengcindezi yokuxhashazwa engxenyeni yesibili yonyaka, okuholela ekwehleni okukhulu kokusekelwa kwezindleko kwamabhizinisi we-PO usebenzisa indlela ye-chlorohydrin;

I-Dench Side: I-Downstream Isidingo se-polyther iyisicaba, ngentshiseko yesilinganiso semibuzo emakethe, ukuthunyelwa okuzinzile okuvela kubakhiqizi abahlukahlukene, ikakhulukazi kususelwa kububanzi bentengo yakamuva ye-EPDM. Ukuthengwa kwengqondo kwamabhizinisi nakho kuqapha futhi, ikakhulukazi ukugcina isidingo esiqinile.

Sekukonke, imakethe ye-propylene emphethweni wezinto ezibonakalayo eluhlaza ibuthakathaka, kanti imakethe ye-chlorine ye-liquid isebuthakathaka, okwenza kube nzima ukuthuthukisa ukwesekwa kokuphela kwento ebonakalayo; Mayelana nokuhlinzekwa, idivaysi ye-Zhenhai ingahle iqale ekuqaleni kukaMeyi, futhi amadivaysi athile wokuhlola nawo ahlelelwe ukuqhubeka nokulindelwe ngoMeyi. Kungahle kube nokwanda okuthile okutholakalayo ngoMeyi; Isidingo seMakethe ye-Downtream polyther ngokwesilinganiso, kepha kuleli sonto singase singene kancane kancane esiteji ngaphambi kweholide losuku, futhi uhlangothi olufunwa lungaba nomfutho othile ofanele. Ngakho-ke, Sekukonke, imakethe ye-epoxy propane kulindeleke ukuthi ithuthukise ngokuqinile esikhathini esifushane.
