Mutengo wedhayi dzekuparadzira wakakwidzwa zvakare! Jiangsu Tianjiayi Chemical Co., Ltd., iyo yakave nekuputika kwakanyanya musi waKurume 21, ine huwandu hwe17,000 matani / gore rem-phenylenediamine (dhayi yepakati), inova yechipiri yakakura misimboti yekugadzira chirimwa muindasitiri. Kushomeka kwephenylenediamine kupa uye kukwira kwemitengo kwakonzera kukwira kwemitengo yedhayi dzakadzika.

I. Iko kuderedzwa kwekupa kwezvinhu zvakagadzirwa

China's phenylenediamine kugadzirwa simba ingangoita 99,000 matani/gore, zvichiteerana, Zhejiang Longsheng Boka 65,000 matani/gore, Sichuan Hongguang Special Chemical Co., Ltd. 17,000 matani/gore, Jiangsu Tianjiayi Chemical Co., Ltd. 17,000 matani/year. Njodzi yekuputika ichakanganisa nezve 20% yehuwandu hwemusika we m-phenylenediamine, iyo inotungamira zvakananga kuwedzera kwemutengo we m-phenylenediamine, uye iyo yakadzika inoparadzira dhayi musika ichasimukawo.

Mashoko atiri kutambira anoti musi wakaitika tsaona iyi, mamwe makambani anodhidhadhayi nemakambani epakati ambomira kupihwa maodha. Mitengo chaiyo yekutengeserana kwedhayi yekuparadzira yakawedzera mumazuva maviri apfuura. Mutengo wekare-fekitari we m-phenylenediamine wakasimuka kubva ku USD7100 / MT kusvika ku USD15,000 / MT, mutengo wekutengesa hauzivikanwi. Kunze kwezvo, madhayi ekuparadzira akatangawo kuwedzera mitengo kubva munaKurume 24, achitora Disperse Blue 56, Disperse Red 60 semuenzaniso. Parizvino, mutengo weDisperse Blue 56 ndeye 25.45 ~ 31.30 USD/kg.

II. Zvinhu zvakawanda zvinosimudzira

Pamusoro pezvinhu zvakakanganisika netsaona yekuputika, kukwira kwemutengo kwedhayi dzakapararira kwakabatana neazvino kuderera kwemabhizinesi epasi uye kudzikira kwehuwandu hwekugadzira.

MunaKurume, mabhizinesi ekudhinda uye kudhaya akange asina kubatikana mumwaka wepamusoro, uye mutengo wekuparadzira dhayi waive wakanyanya kuderera. Chiyero chekuparadzira dhayi mumabhizinesi ekudhinda uye kudhayira uye vagovani yaive yakaderera pane iyo panguva imwechete yegore rapfuura. Mushure mekuputika, musika unowanzo wedzera madhayi. Pasi pepfungwa yekudonha, mirairo yemutengi yakawedzera, zvichiita kuti mutengo wekuparadzira dhayi ukwire.

Kunze kwezvo, kuderedzwa kwekuparadzira dhayi kugona zvakare chikonzero chakakosha. Zvinonzwisiswa kuti kune anenge 150,000 matani / gore rekuparadzira dhayi simba kuchamhembe kweJiangsu mudunhu reChina. Nekuda kwezvinhu zvakaita sekutarisa kuchengetedza kwezvakatipoteredza muna 2018, kugadzirwa kunogumira. Mushure mekunge tsaona yekuputika yakaitika mukambani yakaronga kutangazve kugadzira munguva pfupi, kudzokera kubasa kwave kure. Kunyangwe kana mabhizinesi ega akadzokera kubasa, zvinobuda zvichadzikiswa zvakanyanya.

III. Musika ucharamba wakakwirira.

Muchikamu chekupedzisira, musika wekuparadzira dhayi ucharamba wakakwira.

Panyaya yekupihwa kwezvinhu zvakasvibirira, mushure mekuputika kweTianjiayi, iyo yekugovera chimiro uye chaiyo yekugadzira kugona kwem-phenylenediamine ichaita shanduko huru. Zvinotarisirwa kuti theoretical production simba re phenylenediamine ichaderedzwa kubva kune yapfuura 99,000 toni kusvika 70,000 toni muna 2019. Maererano nekushandiswa, nekuwedzera kwehuwandu hwekugadzira dhayi, zvinotarisirwa kuti kushandiswa kwe phenylenediamine kuchava pamusoro pe80,000 matani. mu 2019. "Pakazere, kupihwa kwem-phenylenediamine kucharamba kuri kupfupi, uye mutengo ungangoramba uchikwira, asi kuwedzera chaiko kunoenderana nekuti Zhejiang Longsheng neSichuan Hongguang vanotengwa sei. Kukwira kwemitengo yezvigadzirwa kuchaunza tsigiro yemutengo kumusika wekuparadzira dhayi.

Zvakare, zvakakanganiswa netsaona iyi yekuputika, mabhizinesi emakemikari eiyo nitrification process uye nzira yekudzikisa hydrogenation ichave iri pasi pekuongororwa kwakakosha, zvichikonzera kuwanda kwedhayi nepakati uye nemitengo yakaderera.

Zvinonzi mabhizinesi ane chekuita nedhayi muJiangsu Yancheng Xiangshui Ecological Chemical Industrial Park, akadai seJiangsu Aonkyi Chemical Co., Ltd. uye Jiangsu Zhijiang Chemical Company, parizvino ari kumiswa.

Kubatwa neizvi, madhayi ejena anotarisirwa kuramba achikwira mushure mekuwedzera kwemutengo; Disperse Blue 60, Disperse Blue 56, Disperse Red 60 icharamba ichikwira, izvo zvinozoita kuti mamwe madhayi awedzere pamwechete.
