1,Amandla orhwebo ezinto ezikrwada

1.Bisphenol A: Kwiveki ephelileyo, ixabiso lendawo yebisphenol A libonise ukuguquguquka okunyukayo. Ukususela ngoJanuwari 12 ukuya kwi-15 kaJanuwari, i-bisphenol A imakethi yahlala izinzile, kunye nabavelisi bathumela ngokuhambelana nemveliso yabo kunye neentengiso zokuthengisa, ngelixa abathengi abasezantsi kwiimfuno eziphuthumayo benza ukuthenga okuguquguqukayo ngokusekelwe kwiimeko zemarike.

Nangona kunjalo, ukususela ngoLwesibini, ixabiso lezinto eziluhlaza ze-benzene ecocekileyo linyuke kakhulu, likhokelela ekunyukeni okuhambelanayo kwexabiso le-phenolic ketones, ngaloo ndlela kwandisa iindleko zokuvelisa i-bisphenol A. Ukujongana nale meko, ukuzimisela kwabavelisi kunye nabameli ukwanda kwamaxabiso kuye kwanda kakhulu. Kwangaxeshanye, iimarike ezisezantsi nazo zigcina isitokhwe, zikhuthaza ukwanda komsebenzi wokurhweba kwimarike ye-bisphenol A. Ngenxa yoko, amaxabiso emarike kwimimandla eyahlukeneyo afumene amanqanaba ahlukeneyo okunyuka. NgoLwesine kusasa kurhweba, ixabiso elicatshulweyo lesiqhelo le-bisphenol A linyuke laya kutsho kuma-9600 yuan/toni, kwaye amaxabiso kwezinye iingingqi nawo anyukile. Nangona kunjalo, ngenxa yokunyuka kwamaxabiso kunye nokudityaniswa okuncinci kwamaxabiso ezinto eziluhlaza, umdla wokuthenga kwimarike esezantsi uphole, kwaye imeko yentengiselwano yezinga eliphezulu iye yaba buthathaka.

Idatha ibonisa ukuba izinga lokusebenza kweshishini lifikelele kwi-70.51% kwiveki ephelileyo, ukunyuka kwe-3.46% xa kuthelekiswa neveki edlulileyo. Ukususela ngomhla we-19 kaJanuwari, ixabiso eliqhelekileyo le-bisphenol A e-East China lisekelwe kwi-9500-9550 yuan / ton, ukunyuka kwe-75 yuan / ton xa kuthelekiswa noJanuwari 12.

2. I-Epichlorohydrin: Kwiveki ephelileyo, imarike ye-epichlorohydrin isebenze ngokuthe chu. Ngeveki, ngenxa yokunyuka kwamaxabiso ezinto eziluhlaza zepropylene kunye neklorini yolwelo, kunye nohlengahlengiso olubuthathaka lwe-glycerol, iindleko zemveliso zokulungiselela i-epichlorohydrin usebenzisa indlela ye-propylene iye yanda, kwaye inqanaba lenzuzo enkulu liye lancipha ngokuhambelanayo.

Okwangoku, unikezelo lwemarike kunye nemfuno imeko ibuthathaka, kwaye abavelisi ngokubanzi banesimo sengqondo sokulumka, kunye neekowuteshini ezizinzileyo. Kuyaphawuleka ukuba amaziko afana ne-Dongying Liancheng, iQela le-Binhua, kunye neZhejiang Zhenyang zisekwimo yokuvalwa, ngelixa amanye amashishini emveliso egxile kakhulu kwimveliso kunye nokuzisebenzisa, kunye nezixhobo ezifumanekayo zamabala zinqabile. Nangona kunjalo, abanye abarhwebi abanalo ukuzithemba kwimarike yexesha elizayo, okubangelwa ubukho bempahla ephantsi kwimarike. Imfuno yemarike esezantsi igcwele emva kokuzaliswa kwakhona kwinqanaba lokuqala, okubangele ukuhla kwemibuzo yee-odolo ezintsha ezingena kwimarike. Ukongeza, njengoko iholide yoMnyhadala weNtwasahlobo isondela, amanye amashishini asezantsi angathatha iholide kwangethuba, nto leyo ewenza buthathaka ngakumbi umoya wokurhweba kwiimarike. Ngeli xesha, iintengiselwano zokwenyani zinokuxoxisana ngokuguquguqukayo.

Ngokumalunga nezixhobo, izinga lokusebenza kweshishini lahlala likwinqanaba le-42.01% kwiveki ephelileyo. Ukusukela nge-19 kaJanuwari, ixabiso lothethwano oluphambili lwe-epichlorohydrin eMpuma China lusekwe kwi-8300-8400 yuan/ton.

2,Uhlalutyo lwemeko yonikezelo

Kwiveki ephelileyo, imeko yokusebenza yasekhayaepoxy resiniifektri ziphucuke kancinane. Ngokukodwa, izinga lokusebenza kwe-resin engama-50.15%, ngelixa izinga lokusebenza kwe-resin eqinile yi-41.56%. Umlinganiselo wokusebenza kolu shishino uwonke ufikelele kuma-46.34%, ukwanda nge-0% xa kuthelekiswa neveki ephelileyo. Ukususela kwisimo sokusebenza, ezininzi izixhobo ze-resin zamanzi zigcina ukusebenza okuzinzileyo, ngelixa izixhobo eziqinileyo ze-resin zigcina amanqanaba aqhelekileyo. Ngokubanzi, izinga lokusebenza kwishishini langoku liphantsi, kwaye kukho unikezelo olwaneleyo lwempahla kwisiza.

3,Utshintsho kwicala lemfuno

Imfuno iyonke kwimarike esezantsi inika uphawu lokuthengwa kwempahla okunyanzelekileyo, kunye nemfuno enyiniweyo. Kwangaxeshanye, amanye amashishini asezantsi athe ngcembe angena kwindawo yokupaka, nto leyo eyenza buthathaka ngakumbi imfuno yemarike.

4,Uqikelelo lweMarike yekamva

Kulindeleke ukuba imarike ye-epoxy resin iya kugcina ukuguquguquka okuphantsi kule veki. Utshintsho lwamaxabiso kwicala leendleko kulindeleke ukuba luhlale luzinzile, ngelixa ukulandelelwa kweemfuno zemarike esezantsi kuya kunqunyulwa. Njengoko amanye amashishini asezantsi ngokuthe ngcembe erhoxa kwiimarike ngeeholide, umoya wokurhweba kwiimarike unokuqhubeka uthe cwaka. Kule meko, kubasebenzisi botshintshiselwano baya kuba balumke ngakumbi ekujongeni ukuguquka kweemarike kunye notshintsho kwimfuno, ngelixa bekwanika ingqalelo kwiimarike ezinyukayo nezisezantsi kunye nophuhliso lwemfuno.
