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. ʻO ka pōʻino pahū e pili ana i ka 20% o ka mākeke o ka m-phenylenediamine, e alakaʻi pololei 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 ulia pōpilikia, 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 hoʻopuehu i ka wai ma ka ʻākau o Jiangsu ʻāina ʻo Kina. Ma muli o nā kumu e like me ka nānā ʻana i ka mālama kaiapuni i 2018, ua kaupalena ʻia ka hana. Ma hope o ka hopena o ka pōʻino i loko o ka hui i hoʻolālā e hoʻomaka hou i ka hana ʻana, 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 ana 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 ke ʻano hoʻolako 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 i 70,000 tons ma 2019. Ma ke ʻano o ka hoʻohana ʻana, me ka piʻi ʻana o ka hiki ke hana wai, ua manaʻo ʻia e ʻoi aku ka nui o ka phenylenediamine ma mua o 80,000 tons. i 2019. "Ma keʻano holoʻokoʻa, e hoʻomau ka hoʻolako ʻana i ka m-phenylenediamine, a e piʻi mau ana ke kumukūʻai, akā ʻo ka hoʻonui kikoʻī e pili ana i ke kumu kūʻai ʻia 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 mea pena a me nā mea waena a me nā kumukūʻai haʻahaʻa.

Ua hōʻike ʻia ʻo nā ʻoihana pili i ka wai ma 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 o ka 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 ka Disperse Blue 60, Disperse Blue 56, Disperse Red 60, a ʻo ia ka mea e alakaʻi ai i nā mea pena e hoʻonui pū.
