Kuleli sonto, imakethe ye-epoxy resin yasekhaya ixubene. Phakathi nesonto, isikhungo samandla adonsela phansi semakethe ye-liquid resin besibuthakathaka, kanti imakethe ye-solid resin ibike ukwanda. Kusukela ekupheleni kukaJanuwari 7, intengo eyinhloko ye-liquid resin emakethe yaseMpumalanga China ibhekiselwa ku-20,500-21,500 yuan/ton emigqonyeni yokwamukela. Ngokuphathelene nezinto zokusetshenziswa, i-bisphenol A yezinto zokusetshenziswa eziyinhloko iyeke ukwehla futhi yabuya, kanti enye i-epichlorohydrin yezinto zokusetshenziswa eziluhlaza yehla futhi. Ngokuphathelene nokuhlinzekwa kanye nesidingo, imakethe ye-epoxy resin ibilokhu isebenza kahle phakathi nesonto, futhi izinga lokusebenza liye landa kancane kancane. Kodwa-ke, imakethe ye-epoxy resin yamanje ingene esikhathini sokuphumula futhi isidingo siye sancipha.

Ekuqaleni kuka-2021, ukugxila kwemakethe ye-epoxy resin kukhuphuke kakhulu. Ngenxa yokumiswa okufushane kwemishini eluhlaza kanye nokuntuleka kokuhlinzekwa, ukwesekwa kwezindleko zamanje kuqinisiwe, futhi ukunikezwa kwabakhiqizi be-resin kuye kwanda.

Ama-noodle aluhlaza
I-Bisphenol A: Kuleli sonto, imakethe ye-bisphenol A yashintsha futhi yabuya. Phakathi nesonto, imakethe ye-bisphenol A yashintsha umkhuba wayo wokwehla futhi okunikezwayo kwanda kancane kancane. I-phenol yezinto zokusetshenziswa igijima kancane, isikhungo samandla adonsela phansi se-acetone siyakhuphuka, futhi uhlangothi lwezindleko luvame ukusekelwa. Ngokuphathelene nokunikezwa, isitshalo se-bisphenol A sishintshe kakhulu kuleli sonto, futhi izinga lokusebenza lehlile. Izinga lokusebenza lilonke lalicishe libe ngu-60%. Phakathi kwabo, umthwalo we-Nantong Xingchen wehle wafika ku-40%. Isitshalo se-Sinopec Mitsubishi savalwa okwesikhashana, futhi ukunikezwa kwasendaweni kwakuncane. Ngokuphathelene nesidingo, ama-PC amakhulu aphansi aqale ehla abese ekhuphuka, ukusebenza kokuthengiselana kwakwamukelekile, futhi ama-resin e-epoxy ayengalandeli. Kusukela ekupheleni kukaJanuwari 7, intengo exoxiswana ngayo ye-BPA eMpumalanga China izolethwa ku-RMB 12,900-13,000/ton.

I-Epichlorohydrin: Kuleli sonto, i-epichlorohydrin isebenza kancane. Phakathi nesonto, okunikezwayo kwabakhiqizi bekuntula ukwesekwa okuhle, futhi imakethe ye-epichlorohydrin yaqhubeka nokwehla. I-propylene kanye ne-glycerin yezinto zokusetshenziswa zihlelwe ngezikhathi ezithile, futhi uhlangothi lwezindleko alushintshi kakhulu. Ngasohlangothini lokuhlinzekwa, umthwalo wesitshalo se-epichlorohydrin saleli sonto uhlale uphansi, izinga lokusebenza kwemboni lalicishe libe ngu-45%, isitshalo saseShandong Binhua saqala kabusha, kanti i-Ningbo Huanyang yavalwa ukuze kulungiswe. Ngokuphathelene nesidingo, imakethe ye-resin engezansi ibanda, futhi isidingo kunzima ukusithuthukisa. Kusukela ekupheleni kukaJanuwari 7, intengo ekhulunywe ngayo ye-epichlorohydrin eMpumalanga China yalethwa ku-11300-11400 yuan/ton.

Uhlangothi lokuhlinzeka
Kuleli sonto, izinga lokusebenza kwesitshalo se-resin eliwuketshezi ligcinwe cishe ku-60%, futhi ukutholakala kwendawo bekukuningi. Imboni yayo ye-China Capital Chemical yayisesesimweni sokuvalwa, futhi usuku lokuqala belungakacaci. Kunzima ukwandisa umthwalo wesitshalo se-resin esiqinile, futhi izinga lokusebenza licishe libe ngu-40%. Phakathi kwazo, ukulungiswa kobuchwepheshe be-Huangshan Jinfeng kuyama, futhi isimo sokuxoxisana sonke kunzima ukusithuthukisa.

Uhlangothi lwesidingo
Njengamanje, imakethe ye-resin isadingeka kakhulu ngesikhathi sokuphumula, imibuzo engezansi ayiyona intshiseko, futhi ukuthengiselana akujwayelekile kakhulu. Imizwa yokwehla kwemboni iyanda, futhi ukusebenza kuyaqapha, futhi isimo samanje kunzima ukusishintsha.

Isibikezelo se-Outlook

Ngo-2020, imakethe ye-resin ichithe unyaka "omangalisayo". Ekuqaleni kuka-2021, i-epoxy resin ibonakala ibuthakathaka ngaphansi kokusekelwa yizindleko, kodwa empeleni amaza angaphansi komhlaba ayakhuphuka. Izici eziyinhloko ezithinta imakethe yamanje yilezi ezilandelayo:
Ngasohlangothini lwezinto zokusetshenziswa, i-bisphenol A ingachazwa “njengomnikeli” oyinhloko ekukhuphukeni kwemakethe ye-resin kulo mjikelezo. Kodwa-ke, umthelela omuhle walo mjikelezo wemishini ulinganiselwe. Enye i-epichlorohydrin yezinto zokusetshenziswa ikhombisa ukwehla okuncane, futhi ukwesekwa kwezindleko akukuhle; uhlangothi lokuhlinzeka, imakethe Endabeni yokusebenza kwemishini yangaphakathi okuzinzile, ukunikezwa kwe-resin spot kwanele, futhi kunzima ukuyisekela; uhlangothi lokufunwa, intengo kanye nesimo semakethe esingekho kunzima ukusiphula, izimboni ezisebenzisa iningi lempahla, kanti izinga lokufunwa lisalokhu libi kakhulu. Kulindeleke ukuthi imakethe ye-epoxy resin yasekhaya izogcina isimo sokulungisa esishintshashintshayo esikhathini esifushane, futhi ukulandelwa kusadingeka kuqaphele ukuguquguquka kwezinto zokusetshenziswa kanye nokunikezwa kanye nesidingo.
