1,Amandla ezimakethe zezinto zokusetshenziswa

1.I-Bisphenol A: Ngesonto eledlule, intengo yendawo ye-bisphenol A ibonise ukuguquguquka okunyukayo. Kusukela ngomhlaka-12 kuJanuwari kuya kuJanuwari 15, imakethe ye-bisphenol A yahlala izinzile, abakhiqizi bemikhumbi ngokuhambisana nokukhiqizwa kwabo kanye nesigqi sokuthengisa, kuyilapho abathengi abangaphansi komfula abanesidingo esiphuthumayo benza ukuthenga okuguquguqukayo ngokusekelwe ezimweni zemakethe.

Kodwa-ke, kusukela ngoLwesibili, intengo yezinto ezingavuthiwe i-benzene ehlanzekile ikhuphuke kakhulu, okuholele ekwenyukeni okufanayo kwentengo yama-phenolic ketones, ngaleyo ndlela kwenyusa izindleko zokukhiqiza i-bisphenol A. Ngokubhekene nalesi simo, ukuzimisela kwabakhiqizi nabaxhumanisi ukwanda kwamanani kuye kwanda kakhulu. Ngesikhathi esifanayo, izimakethe ezingezansi zibuye zigcine ngokukhuthele, zikhuthaza ukwanda komsebenzi wokuhweba emakethe ye-bisphenol A. Ngenxa yalokho, amanani emakethe ezifundeni ezihlukahlukene ahlangabezane namazinga ahlukene okunyuka. NgoLwesine ekuseni ukuhweba, inani elicashuniwe elivamile le-bisphenol A lase likhuphuke lafinyelela cishe ku-9600 yuan/ton, futhi izintengo kwezinye izifunda zase zinyukile. Kodwa-ke, ngenxa yokuntenga nokuqiniswa kancane kwamanani entengo yezinto ezingavuthiwe, umdlandla wokuthenga emakethe esezansi nomfula wehlile, futhi isimo sezinga eliphezulu sokuthenga sehlile.

Imininingwane ikhombisa ukuthi izinga lokusebenza kwale mboni lifinyelele ku-70.51% ngesonto eledlule, nokunyuke ngo-3.46% uma kuqhathaniswa nesonto eledlule. Kusukela ngomhla ka-19 Januwari, intengo enkulu okuxoxisnwe ngayo ye-bisphenol A e-East China isuselwe ku-9500-9550 yuan/ton, okuwukunyuka kwama-yuan/ton angama-75 uma kuqhathaniswa noJanuwari 12.

2. I-Epichlorohydrin: Ngesonto eledlule, imakethe ye-epichlorohydrin isebenze kancane. Phakathi nesonto, ngenxa yokukhuphuka kwamanani entengo yezinto ezingavuthiwe ipropylene ne-liquid chlorine, kanye nokulungiswa okubuthakathaka kwe-glycerol, izindleko zokukhiqiza zokulungiselela i-epichlorohydrin kusetshenziswa indlela ye-propylene zinyukile, futhi izinga lenzuzo yonke liye lehla ngokufanayo.

Okwamanje, isimo sokuhlinzekwa kwemakethe kanye nesidingo sibuthakathaka uma kuqhathaniswa, futhi abakhiqizi ngokuvamile banesimo sengqondo sokuqapha, ngamakhotheshini azinzile. Kuyaphawuleka ukuthi izikhungo ezifana ne-Dongying Liancheng, i-Binhua Group, ne-Zhejiang Zhenyang zisasesimweni sokuvalwa, kanti amanye amabhizinisi okukhiqiza agxile kakhulu ekukhiqizeni nasekuzisebenziseni wona, futhi izinsiza ezitholakalayo ziyindlala. Kodwa-ke, abanye abadayisi abanakho ukuzethemba emakethe yesikhathi esizayo, okuholela ekubeni khona kwezimpahla ezinenani eliphansi emakethe. Isidingo semakethe ephansi sesigcwele ngemuva kokugcwaliswa kabusha ekuqaleni, okuholele ekwehleni kwemibuzo yama-oda amasha angena emakethe. Ukwengeza, njengoba iholide loMkhosi Wasentwasahlobo lisondela, amanye amabhizinisi angezansi angase athathe iholidi ngaphambi kwesikhathi, okwenza buthaka kakhulu isimo sokuhweba emakethe. Okwamanje, okwenziwayo kwangempela kungaxoxiswana ngakho ngendlela evumelana nezimo.

Mayelana nezinsizakusebenza, izinga lokusebenza kwemboni lilokhu lisezingeni lama-42.01% ngesonto eledlule. Kusukela ngomhlaka-19 Januwari, intengo okuxoxiswene ngayo ye-epichlorohydrin eMpumalanga China isekelwe ku-8300-8400 yuan/ton.

2,Ukuhlaziywa kwesimo sokuhlinzeka

Ngesonto eledlule, isimo sokusebenza sasekhayai-epoxy resinizimboni zithuthuke kancane. Ngokuqondile, izinga lokusebenza le-resin ewuketshezi lingama-50.15%, kanti izinga lokusebenza le-resin eqinile lingama-41.56%. Lilonke izinga lokusebenza kwale mboni lifinyelele ku-46.34%, nokunyuke ngo-0% uma kuqhathaniswa nesonto eledlule. Kusukela esimweni sokusebenza, amadivaysi amaningi e-resin ewuketshezi agcina ukusebenza okuzinzile, kuyilapho amadivaysi e-resin eqinile egcina amazinga ajwayelekile. Sekukonke, izinga lokusebenza lemboni yamanje liphansi, futhi kukhona ukuhlinzekwa okwanele kwempahla esizeni.

3,Izinguquko ohlangothini lwesidingo

Isidingo sisonke emakethe esezansi nomfula sibonisa imfanelo yokuthengwa kwempahla eyisibopho, enesidingo esilinganiselwe. Ngaso leso sikhathi, amanye amabhizinisi asezansi nomfula angena kancane kancane esimweni sokupaka, okwenza kube buthaka isidingo semakethe.

4,Isibikezelo Semakethe Esizayo

Kulindeleke ukuthi imakethe ye-epoxy resin izogcina ukuguquguquka okuphansi kuleli sonto. Izinguquko zentengo ngasohlangothini lwezindleko kulindeleke ukuthi zihlale zizinzile, kuyilapho ukulandelwa kwesidingo semakethe ephansi nakho kuzonqunyelwa. Njengoba amanye amabhizinisi asezansi nomfula kancane kancane ehoxa emakethe ngamaholide, isimo sokuhweba emakethe singase siqhubeke sithule. Kulesi simo, opharetha bezohwebo bazoqaphela kakhulu ekubhekeni ukuguquguquka kwemakethe kanye nezinguquko ezifunwayo, kuyilapho futhi benaka ukuguquguquka kwezimakethe ezikhuphuka nomfula kanye nokuthuthukiswa kwesidingo.
