Ua hoʻokiʻekiʻe hou ʻia ke kumukūʻai o nā mea hoʻonaninani!ʻO Jiangsu Tianjiayi Chemical Co., Ltd., ka mea i pahū nui loa i ka lā Malaki 21, he 17,000 tons/makahiki ka m-phenylenediamine (dye intermediate), ʻo ia ka lua o nā mea kanu kumu nui ma ka ʻoihana.ʻO ka liʻiliʻi o ka lako phenylenediamine a me ka piʻi ʻana o nā kumukūʻai i alakaʻi i ka piʻi ʻana o nā kumukūʻai o nā wai hoʻopuehu i lalo.

I. ʻO ka hoʻemi ʻia ʻana o nā lako maka

ʻO ka nui o ka hana phenylenediamine o Kina ma kahi o 99,000 tons / makahiki, kēlā me kēia, Zhejiang Longsheng Group 65,000 tons / makahiki, Sichuan Hongguang Special Chemical Co., Ltd. 17,000 tons / makahiki, Jiangsu Tianjiayi Chemical Co., Ltd. 17,000 tons / makahiki.E pili ana ka ulia pahū ma kahi o 20% o ka mākeke o ka m-phenylenediamine, kahi e alakaʻi pololei ai i ka piʻi ʻana o ke kumukūʻai o ka m-phenylenediamine, a e piʻi aʻe ka mākeke disperse dye ma lalo.

Wahi a nā hōʻike, i ka lā o ka pōʻino, ua hoʻōki kekahi mau hui dye a me nā hui waena i ka loaʻa ʻana o nā kauoha.Ua piʻi aʻe nā kumukūʻai kūʻai maoli o nā wai kala i nā lā ʻelua i hala.Ua piʻi ke kumukūʻai ex-factory o m-phenylenediamine mai USD7100 / MT a i USD15,000 / MT, ʻaʻole ʻike ʻia ke kumukūʻai kūʻai.Ma waho aʻe o kēia, ua hoʻomaka ka hoʻonui ʻana i nā helu mai Malaki 24, e lawe ana i ka Disperse Blue 56, Disperse Red 60 i laʻana.I kēia manawa, ʻo ke kumukūʻai o Disperse Blue 56 he 25.45 ~ 31.30 USD / kg.

II.Nui nā kumu e hoʻonui

Ma kahi o nā mea i hoʻopilikia ʻia e ka pōʻino pahū, ua pili ka piʻi ʻana o ke kumukūʻai o nā disperse dyes me ka haʻahaʻa haʻahaʻa o nā ʻoihana o lalo a me ka emi ʻana o ka hiki ke hana.

I Malaki, ʻaʻole paʻa nā ʻoihana paʻi a me ka hoʻoluʻu ʻana i ka wā kiʻekiʻe, a ʻo ke kumu kūʻai o nā disperse dyes he haʻahaʻa loa.ʻO ke kiʻekiʻe o ka disperse dyes i ka paʻi ʻana a me ka waihoʻoluʻu ʻana i nā ʻoihana a me nā mea hoʻolaha i haʻahaʻa ma mua o ka manawa like o ka makahiki i hala.Ma hope o ka pahū ʻana, hoʻopuehu pinepine ka mākeke i nā kala.Ma lalo o ka hopena noʻonoʻo o ka hāʻule, ua piʻi nā kauoha a ka mea kūʻai aku, e alakaʻi ana i ke kumu kūʻai o nā disperse dyes e piʻi aʻe.

Ma waho aʻe, ʻo ka hoʻemi ʻana i ka mana disperse dye kekahi kumu nui.Ua hoʻomaopopo ʻia aia ma kahi o 150,000 tons/makahiki o ka hiki ke hoʻoheheʻe ʻia ma ka ʻākau o Jiangsu ʻāina ʻo Kina.Ma muli o nā kumu e like me ka nānā ʻana i ka mālama ʻana i ke kaiapuni ma 2018, ua kaupalena ʻia ka hana.Ma hope o ka hopena o ka pōʻino i loko o ka hui i hoʻolālā e hoʻomaka koke i ka hana, ua lilo ka hoʻi i ka hana.ʻOiai inā hoʻi nā ʻoihana pākahi i ka hana, e hoʻemi nui ʻia ka hopena.

III.E noho kiʻekiʻe ka mākeke.

I ka pae hope, e mau ka mākeke disperse dye kiʻekiʻe.

Ma ke ʻano o ka lako lako maka, ma hope o ka pahū ʻana o Tianjiayi, e hoʻololi nui ʻia ka hoʻolako ʻana a me ka mana hana maoli o ka m-phenylenediamine.Manaʻo ʻia e hoʻemi ʻia ka mana o ka phenylenediamine mai ka 99,000 tons i hala a i ka 70,000 tons ma 2019. Ma ke ʻano o ka hoʻohana ʻana, me ka hoʻonui ʻana i ka hiki ke hana wai, ua manaʻo ʻia e ʻoi aku ka nui o ka phenylenediamine ma mua o 80,000 tons. ma 2019. "Ma keʻano holoʻokoʻa, e hoʻomau ka hoʻolako ʻana i ka m-phenylenediamine, a e hoʻomau ʻia ke kumukūʻai, akā ʻo ka hoʻonui kikoʻī e pili ana i ke kumukūʻai ʻo Zhejiang Longsheng a me Sichuan Hongguang.ʻO ka piʻi ʻana o nā kumukūʻai maka e lawe mai i ke kākoʻo kumu kūʻai i ka mākeke disperse dye.

Eia kekahi, i hoʻopilikia ʻia e kēia pōʻino pahū, ʻo nā ʻoihana kemika o ke kaʻina nitrification a me ke kaʻina hana hoʻohaʻahaʻa hydrogenation e kau ʻia i ka hōʻoia koʻikoʻi, e hopena i ka hāʻawi ʻana i nā dyes a me nā waena a me nā kumukūʻai haʻahaʻa.

Ua hōʻike ʻia ʻo nā ʻoihana pili i ka wai i loko o Jiangsu Yancheng Xiangshui Ecological Chemical Industrial Park, e like me Jiangsu Aonkyi Chemical Co., Ltd. a me Jiangsu Zhijiang Chemical Company, i kēia manawa i kahi kūlana hoʻomaha.

Ma muli o kēia, ua manaʻo ʻia e piʻi mau nā wai melemele ma hope o ka piʻi mau ʻana o ke kumukūʻai;E piʻi mau ana ʻo Disperse Blue 60, Disperse Blue 56, Disperse Red 60, ʻo ia ka mea e alakaʻi ai i nā mea pena e hoʻonui pū.
