Theko ea lidae tse jalang e ile ea phahamisoa hape! Jiangsu Tianjiayi Chemical Co., Ltd., e bileng le ho phatloha ho hoholo ka ho khetheha ka la 21 Hlakubele, e na le matla a lithane tse 17,000 / selemo tsa m-phenylenediamine (dae e bohareng), e leng setsi sa bobeli se seholo sa tlhahiso ea mantlha indastering. Khaello ea phepelo ea phenylenediamine le litheko tse ntseng li phahama li lebisitse ho phahama ha litheko tsa lidae tse qhalaneng ka tlase ho noka.

I. Phepelo e fokotsehileng ea thepa e tala

Bokhoni ba tlhahiso ea phenylenediamine ea Chaena bo ka bang lithane tse 99,000 ka selemo, ka ho latellana, Zhejiang Longsheng Group 65,000 tons/year, Sichuan Hongguang Special Chemical Co., Ltd. 17,000 tons/year, Jiangsu Tianjiayi Chemical Co., Ltd. 17,000 tons/year. Kotsi ea ho phatloha e tla ama hoo e ka bang 20% ​​ea matla a 'maraka a m-phenylenediamine, e leng se tla lebisa ka ho toba ho eketseha ha theko ea m-phenylenediamine,' me 'maraka oa dae o qhalaneng o tla phahama.

Ho ea ka litlaleho, letsatsing la kotsi, lik'hamphani tse ling tse qhalakanyang dae le lik'hamphani tsa lipakeng li emisitse ho fumana litaelo. Litheko tsa 'nete tsa thekiso ea lidae tse hasantsoeng li eketsehile matsatsing a mabeli a fetileng. Theko ea khale ea fektheri ea m-phenylenediamine e nyolohile ho tloha USD7100 / MT ho ea ho USD15,000 / MT, theko ea transaction ha e tsejoe. Ntle le moo, lidae tse hasantsoeng le tsona li ile tsa qala ho eketsa litheko ho tloha ka la 24 Hlakubele, ho nka Disperse Blue 56, Disperse Red 60 joalo ka mohlala. Hona joale, theko ea Disperse Blue 56 ke 25.45 ~ 31.30 USD / kg.

II. Lintlha tse ngata lia phahama

Ntle le likarolo tse anngoeng ke kotsi ea ho phatloha, ho eketseha ha theko ea lidae tse qhalakaneng ho ne ho amana haholo le lethathamo la morao tjena la likhoebo tse tlase le ho fokotseha ha matla a tlhahiso.

Ka March, likhoebo tsa khatiso le ho daea li ne li sa phathahane nakong ea tlhōrō, 'me theko ea lidae tse qhalakaneng e ne e le tlaase haholo. Boemo ba lidae tse qhalakantsoeng likhoebong tsa khatiso le ho daea le baabi bo ne bo le tlase ho feta ba nakong e tšoanang ea selemo se fetileng. Kamora ho phatloha, 'maraka ka kakaretso o jala lidae. Tlas'a tšusumetso ea kelello ea ho oa, litaelo tsa moreki li ile tsa phahama, tsa khanna theko ea lidae tse qhalakaneng hore e nyolohe.

Ntle le moo, phokotso ea matla a dae e qhalaneng le eona ke lebaka la bohlokoa. Ho utloisisoa hore ho na le lithane tse ka bang 150,000 / selemo tsa matla a dae a qhalakaneng profinseng e ka leboea ea Jiangsu China. Ka lebaka la lintlha tse kang tlhokomelo ea ts'ireletso ea tikoloho ka 2018, tlhahiso e fokotsehile. Ka mor'a hore kotsi ea ho phatloha e hlahe k'hamphaning e rerileng ho tsosolosa tlhahiso haufinyane, ho khutlela mosebetsing ho se ho fihlile hōle. Leha likhoebo ka bomong li ka khutlela mosebetsing, tlhahiso e tla fokotseha haholo.

III. 'Maraka o tla lula o le holimo.

Qetellong, 'maraka oa dae o qhalaneng o tla lula o le holimo.

Mabapi le phepelo ea lihlahisoa tse tala, ka mor'a ho phatloha ha Tianjiayi, mohaho oa phepelo le matla a sebele a tlhahiso ea m-phenylenediamine o tla ba le liphetoho tse kholo. Ho lebeletsoe hore matla a tlhahiso ea tlhahiso ea phenylenediamine a fokotsehe ho tloha ho lithane tse 99,000 tse fetileng ho ea ho lithane tse 70,000 ka 2019. Mabapi le tšebeliso, ka keketseho ea bokhoni ba tlhahiso ea dae, ho lebeletsoe hore tšebeliso ea phenylenediamine e tla feta lithane tse 80,000. ka 2019. “Ka kakaretso, phepelo ea m-phenylenediamine e tla tsoela pele ho ba e khutšoanyane, 'me theko e ka' na ea tsoela pele ho phahama, empa keketseho e khethehileng e itšetlehile ka hore na Zhejiang Longsheng le Sichuan Hongguang li rekoa joang. Ho phahama ha litheko tsa thepa e tala ho tla tlisa tšehetso ea litšenyehelo 'marakeng oa dae o qhalaneng.

Hape, e anngoeng ke kotsi ena ea ho phatloha, lik'hamphani tsa lik'hemik'hale tsa ts'ebetso ea nitrification le ts'ebetso ea ho fokotsa hydrogenation li tla ba tlas'a netefatso ea bohlokoa, e leng se etsang hore ho be le phepelo e ngata ea lidae le li-intermediate le theko e tlaase.

Ho tlalehoa hore likhoebo tse amanang le dae tse Jiangsu Yancheng Xiangshui Ecological Chemical Industrial Park, tse kang Jiangsu Aonkyi Chemical Co., Ltd. le Jiangsu Zhijiang Chemical Company, li ntse li emisitsoe.

E anngoe ke sena, li-dyes tse mosehla li lebeletsoe hore li tsoele pele ho phahama ka mor'a ho eketseha ha theko e tsoelang pele; Disperse Blue 60, Disperse Blue 56, Disperse Red 60 le eona e tla tsoela pele ho phahama, e leng se tla lebisa lidae tse ling ho eketseha hammoho.
