Ixabiso ledayi ezisasazwayo lanyuswa kwakhona! I-Jiangsu Tianjiayi Chemical Co., Ltd., eyayinoqhushumbo olunzima kakhulu ngo-Matshi 21, inomthamo weetoni ze-17,000 / ngonyaka we-m-phenylenediamine (idayi ephakathi), eyindawo yesibini enkulu yokuvelisa imveliso kwishishini. Ukunqongophala kobonelelo lwe-phenylenediamine kunye nokunyuka kwamaxabiso kuye kwakhokelela ekunyukeni kwamaxabiso edayi ezisasazwayo ezisezantsi.

I. Unikezelo oluncitshisiweyo lwemathiriyeli ekrwada

Umthamo wemveliso ye-phenylenediamine yaseTshayina imalunga neetoni ezingama-99,000/ngonyaka, ngokulandelelanayo, iQela leZhejiang Longsheng iitoni ezingama-65,000/ngonyaka, iSichuan Hongguang Special Chemical Co., Ltd. 17,000 yeetoni/ngonyaka, iJiangsu Tianjiayi Chemical Co., Ltd. 17,000 yeetoni zeChemical Co., Ltd. Ingozi yokuqhuma iya kuchaphazela malunga ne-20% yomthamo wemarike ye-m-phenylenediamine, eya kukhokelela ngokuthe ngqo ekunyukeni kwexabiso le-m-phenylenediamine, kunye ne-downstream disaze imakethi yedayi nayo iya kunyuka.

Iingxelo zithi ngomhla wengozi, ezinye iinkampani ezisasaza idayi kunye neenkampani zangaphakathi ziye zayeka ukufumana imiyalelo. Awona maxabiso entengiselwano yeedayi ezisasazwayo anyukile kwezi ntsuku zimbini zidlulileyo. Ixabiso le-ex-factory ye-m-phenylenediamine linyukile ukusuka kwi-USD7100 / MT ukuya kwi-USD15,000 / MT, ixabiso lokuthengiselana alaziwa. Ngaphandle koko, iidayi ezisasazwayo nazo zaqala ukwandisa amaxabiso ukusuka ngoMatshi 24, zithatha iDisperse Blue 56, Disperse Red 60 njengomzekelo. Okwangoku, ixabiso le-Disperse Blue 56 yi-25.45 ~ 31.30 USD / kg.

II. Izinto ezininzi ziyanyusa

Ukongeza kwizinto ezichatshazelwe yingozi yogqabhuko-dubulo, ukunyuka kwexabiso ledayi ezisasazwayo kunxulumene kakhulu noluhlu lwamva nje olusezantsi lwamashishini asezantsi kunye nokuncipha komthamo wemveliso.

Ngo-Matshi, amashishini okushicilela kunye nokudaya awazange axakeke kwixesha eliphakamileyo, kwaye ixabiso leedayi ezisasazwayo lalinzima kakhulu. Inqanaba lokusasaza idayi kumashishini oshicilelo kunye nokudaya kunye nabasabalalisi laliphantsi kunelo xesha lonyaka ophelileyo. Emva kogqabhuko-dubulo, intengiso ngokubanzi isasaza idayi. Ngaphantsi kwempembelelo yengqondo yokuwa, imiyalelo yomthengi yanda, iqhuba ixabiso leedayi ezisasazwayo ukuba linyuke.

Ngaphandle koko, ukuncitshiswa komthamo wedayi osasazekileyo sisizathu esibalulekileyo. Kuyaqondwa ukuba kukho malunga ne-150,000 yeetoni / ngonyaka wokusabalalisa umthamo wedayi kumantla ephondo laseJiangsu eChina. Ngenxa yezinto ezifana nokulawulwa kokusingqongileyo kwi-2018, imveliso ilinganiselwe. Emva kokuba kwenzeke ingozi yokuqhuma kwinkampani ecwangcise ukuphinda iqalise imveliso kungekudala, ukubuyela emsebenzini kuye kwaba kude. Nokuba amashishini ngamanye abuyela emsebenzini, imveliso iya kuncitshiswa kakhulu.

III. Imarike iya kuhlala iphezulu.

Kwinqanaba lokugqibela, imarike yedayi esasazekayo iya kuhlala iphezulu.

Ngokuphathelele ukunikezelwa kwezinto eziluhlaza, emva kokuqhuma kweTianjiayi, isakhiwo sokubonelela kunye nomthamo wangempela wemveliso ye-m-phenylenediamine iya kutshintsha kakhulu. Kulindeleke ukuba amandla okuvelisa i-theoretical ye-phenylenediamine iya kuncitshiswa ukusuka kwiitoni ze-99,000 zangaphambili ukuya kwiitoni ze-70,000 kwi-2019. Ngokubhekiselele kusetyenziso, ngokunyuka komthamo wokuvelisa idayi, kulindeleke ukuba ukusetyenziswa kwe-phenylenediamine kuya kuba ngaphezu kweetoni ezingama-80,000. ngo-2019. "Kuko konke, ukunikezelwa kwe-m-phenylenediamine kuya kuqhubeka kufutshane, kwaye ixabiso linokuthi liqhubeke nokunyuka, kodwa ukunyuka okuthe ngqo kuxhomekeke kwindlela iZhejiang Longsheng kunye neSichuan Hongguang ezixabisa ngayo. Ukunyuka kwamaxabiso ezinto ezikrwada kuya kuzisa inkxaso yeendleko kwintengiso yedayi.

Kwakhona, okuchatshazelwa yile ngozi yokuqhuma, amashishini ekhemikhali yenkqubo ye-nitrification kunye nenkqubo yokunciphisa i-hydrogenation iya kuba phantsi kokuqinisekiswa okubalulekileyo, okukhokelela ekuboneleleni okungakumbi kwedayi kunye ne-intermediates kunye namaxabiso aphantsi.

Kuxelwe ukuba amashishini anxulumene nedayi eJiangsu Yancheng Xiangshui Ecological Chemical Industrial Park, njengeJiangsu Aonkyi Chemical Co., Ltd. kunye neJiangsu Zhijiang Chemical Company, akwimo yokunqunyanyiswa okwangoku.

Ukuchaphazeleka kule nto, iidayi eziphuzi kulindeleke ukuba ziqhubeke nokunyuka emva kokunyuka kwexabiso eliqhubekayo; Ukusabalalisa i-Blue 60, i-Disperse Blue 56, i-Disperse i-Red 60 iya kuqhubeka nokunyuka, okuya kubangela ukuba amanye amadayi anyuke kunye.
