Ukusukela ekupheleni kuka-Epreli, imakethi yasekhaya ye-epoxy propane iphinde yawela kwindlela yokudibanisa isithuba, kunye nomoya odikidiki wokurhweba kunye nomdlalo wemfuno yokubonelela oqhubekayo kwimarike.

Icala lokubonelela: Isityalo saseZhenhai sokuhluza kunye neekhemikhali eMpuma yeChina ayikaqalisi, kwaye iplanti yesathelayithi yepetrochemical ivaliwe ukuphelisa ukunqongophala. Ukusebenza kwemithombo yeendawo kwimarike ye-East China kunokuba nzima kancinci. Nangona kunjalo, unikezelo kwimarike esemantla luninzi kakhulu, kwaye amashishini emveliso ngokubanzi athumela iimpahla, okukhokelela ekuqokeleleni okuncinci koluhlu; Ngokubhekiselele kwizinto eziluhlaza, imarike yepropylene iye yaphuma phantsi, kodwa okwangoku amaxabiso ahlala ephantsi. Emva kweveki ye-stalemate, i-market chlorine ye-liquid market iye yawa phantsi koxinzelelo lokuxhaswa kweentengiso kwisiqingatha sesibini sonyaka, okubangele ukuhla okukhulu kwenkxaso yeendleko kumashishini e-PO asebenzisa indlela ye-chlorohydrin;

Icala lemfuno: Imfuno ephantsi ye-polyether i-flat, kunye ne-avareji yentshiseko yemibuzo yemarike, ukuthunyelwa okuzinzile ukusuka kubakhiqizi abahlukeneyo, ngokuyininzi ngokusekelwe kwimiyalelo yokuhanjiswa, idibaniswe noluhlu lwamaxabiso lwamva nje lwe-EPDM. Ingqondo yokuthenga yamashishini nayo ilumkile, ngakumbi ukugcina imfuno engqongqo.

Ngokubanzi, imarike yepropylene kwisiphelo sezinto eziluhlaza buthathaka, ngelixa i-market chlorine ye-liquid market isenamandla, okwenza kube nzima ukuphucula inkxaso kwisiphelo sezinto eziluhlaza; Ngokubhekiselele kunikezelo, isixhobo seZhenhai sinokuphinda siqalise ekuqaleni kukaMeyi, kwaye ezinye izixhobo zokuhlola kwangaphambili zicetywe ukuba ziphinde ziqalise ukulindela ngoMeyi. Kunokubakho ukunyuka okuthile ekuboneleleni ngoMeyi; Imfuno kwimarike yepolyether esezantsi ingumndilili, kodwa kule veki inokungena ngokuthe ngcembe kwinqanaba lokugcinwa kwempahla ngaphambi kweholide yoSuku lukaMeyi, kwaye icala lemfuno linokuba nokonyuswa okuthile. Ke ngoko, iyonke, imakethi ye-epoxy propane kulindeleke ukuba iphucuke ngokuthe ngcembe kwixesha elifutshane.
