1. Ukuguquguquka kwexabiso lemarike kunye neendlela

Kwikota yesithathu ka-2024, imarike yasekhaya ye-bisphenol A yafumana ukuguquguquka rhoqo ngaphakathi koluhlu, kwaye ekugqibeleni yabonisa i-bearish trend. Ixabiso lemarike eliphakathi kule kota laliyi-9889 yuan / ton, ukunyuka kwe-1.93% xa kuthelekiswa nekota yangaphambili, ukufikelela kwi-187 yuan / ton. Oku kuguquguquka kubangelwe ikakhulu kwimfuno ebuthathaka ngexesha lesiqhelo elingekhoyo (ngoJulayi nango-Agasti), kunye nokonyuka kokuvalwa kunye nokugcinwa kwenkqubo kushishino lwentlaka ye-epoxy resin, okukhokelela kwimfuno enyiniweyo yemarike kunye nabavelisi abajongene nobunzima ekuthumeleni ngenqanawa. Phezu kwazo nje iindleko eziphakamileyo, ilahleko yeshishini iye yaqina, yaye kukho indawo encinane yokuba ababoneleli-nkonzo benze iimvumelwano. Amaxabiso emarike ahlala eguquguquka phakathi koluhlu lwe-9800-10000 yuan/toni eMpuma China. Ukungena kwi "Golden Nine", ukunciphisa ukugcinwa kunye nokunyuka kokunikezelwa kuye kwandisa ngakumbi imeko yokugqithiswa kweemarike. Ngaphandle kwenkxaso yeendleko, ixabiso le-bisphenol A kusenzima ukuzinza, kwaye isiganeko sexesha lexesha elinobuvila liyabonakala.

2, Ukwandiswa kwamandla kunye nokukhula kwemveliso

Kwikota yesithathu, umthamo wemveliso wasekhaya we-bisphenol A ufikelele kwi-5.835 yezigidi zeetoni, ukwanda kweetoni ze-240000 xa kuthelekiswa nekota yesibini, ngokukodwa ekugunyazisweni kwesityalo se-Huizhou Phase II kumazantsi eChina. Ngokubhekiselele kwimveliso, imveliso kwikota yesithathu yayiziitoni ezingama-971900, ukwanda kwe-7.12% xa kuthelekiswa nekota yangaphambili, ukufikelela kwiitoni ezingama-64600. Oku kukhula kubalelwa kwiimpembelelo ezimbini zezixhobo ezitsha ezisetyenziswayo kunye nokunciphisa ukugcinwa kwezixhobo, okukhokelela ekunyukeni okuqhubekayo kwimveliso yasekhaya ye-bisphenol A.

3, Amashishini asezantsi aqala ukwandisa imveliso

Nangona kungekho mandla okuvelisa amatsha aye asebenza kwikota yesithathu, imithwalo yokusebenza ye-PC esezantsi kunye ne-epoxy resin industries iye yanda. Umyinge womthwalo wokusebenza kwishishini lePC yi-78.47%, ukwanda kwe-3.59% xa kuthelekiswa nexesha elidlulileyo; Umyinge wokusebenza komsebenzi we-epoxy resin industry yi-53.95%, ukwanda kwe-3.91% ngenyanga ngenyanga. Oku kubonisa ukuba imfuno ye-bisphenol A kumashishini amabini asezantsi iye yanda, inika inkxaso ethile kumaxabiso emarike.

I-4, Ukwanda koxinzelelo lweendleko kunye nelahleko yoshishino

Kwikota yesithathu, i-avareji yethiyori yeendleko zebisphenol A ishishini linyuke laya kutsho kwi-11078 yuan/toni, ngenyanga yonyuka nge-3.44%, ngenxa yokunyuka kwamaxabiso e-phenol ekrwada. Nangona kunjalo, i-avareji yengeniso ye-industry yehle ukuya kwi-1138 yuan/ton, ukuhla kwe-7.88% xa kuthelekiswa nexesha elidlulileyo, ebonisa uxinzelelo olukhulu lweendleko kwishishini kunye nokuwohloka ngakumbi kwimeko yelahleko. Nangona ukuhla kwexabiso le-acetone ye-acetone ekrwada kuye kwalungiswa, ixabiso lilonke alikakulungeli ukwenza inzuzo kwishishini.

5, Uqikelelo lwemarike kwikota yesine

1) Iindleko zokujonga

Kulindeleke ukuba kwikota yesine, kuya kubakho ukugcinwa okuncinci kwifektri ye-phenol ketone, kunye nokufika kwempahla ephuma kumazwe angaphandle kwi-port, ukunikezelwa kwe-phenol kwimarike kuya kwanda, kwaye kukho ukuhla kwexabiso. . Imarike ye-acetone, kwelinye icala, kulindeleke ukuba ibe nohlengahlengiso olusezantsi kwixabiso ngenxa yobonelelo oluninzi. Utshintsho ekunikezelweni kwee-phenolic ketones luya kulawula indlela yokuthengisa kwaye lubeke uxinzelelo oluthile kwiindleko ze-bisphenol A.

2) Ubonelelo lwengqikelelo yecala

Kukho izicwangciso ezimbalwa zokugcinwa kwezityalo zasekhaya ze-bisphenol A kwikota yesine, kunye nenani elincinci lamalungiselelo olondolozo kwiindawo zaseChangshu naseNingbo. Ngelo xesha, kukho ukulindela ukukhutshwa kwamandla okuvelisa amatsha kwindawo yaseShandong, kwaye kulindeleke ukuba ukunikezelwa kwe-bisphenol A kuya kuhlala kuninzi kwikota yesine.

3) Ukujonga kwicala lemfuno

Imisebenzi yokulondoloza kumashishini asezantsi iyancipha, kodwa imboni ye-epoxy resin ichatshazelwa kukubonelela kunye nokuchasana kwemfuno, kwaye imveliso kulindeleke ukuba ihlale kwinqanaba eliphantsi. Nangona kukho ulindelo lwezixhobo ezitsha eziza kufakwa ekusebenzeni kwishishini lePC, ingqwalasela kufuneka ihlawulwe kwinkqubela yemveliso yangempela kunye nefuthe lezicwangciso zokulondoloza kumthwalo wokusebenza. Lilonke, imfuno esezantsi ayinakwenzeka ukuba ifumane ukukhula okubonakalayo kwikota yesine.

Ngokusekwe kuhlalutyo olubanzi lweendleko, unikezelo, kunye nemfuno, kulindeleke ukuba imakethi ye-bisphenol A iya kusebenza ngokubuthathaka kwikota yesine. Ukuxhaswa kweendleko kuye kwaba buthathaka, ukulindela ukubonelela kuye kwanda, kwaye imfuno esezantsi kunzima ukuyiphucula kakhulu. Imeko yelahleko yeshishini inokuqhubeka okanye yongeze. Ke ngoko, kuyafuneka ukuba kubekwe iliso elibukhali kwimisebenzi yokunciphisa umthwalo nokugcinwa kwayo okungacwangciswanga ngaphakathi kwishishini ukuze kumelwane nemingcipheko enokubakho yokuguquguquka kweemarike.
