Msika wotentha wa titaniyamu wa dioxide kwa zaka zambiri ukupitirizabe kuzizira kuyambira theka lachiwiri la chaka chatha, ndipo mtengo watsika pang'onopang'ono. Mpaka pano, mitengo yosiyanasiyana ya titaniyamu ya dioxide idatsika ndi 20%. Komabe, monga mankhwala apamwamba mu makampani a titaniyamu woipa, njira ya chlorination titaniyamu woipa akadali amphamvu.
"Chlorination titaniyamu woipa ndi chikhalidwe chitukuko cha mkulu-mapeto kusintha kwa makampani China titaniyamu woipa." Mu kotunga msika, zolowa zamakono, kutsogolera ndi ubwino zina, m'zaka zaposachedwapa, zoweta kolorayidi titaniyamu woipa kupanga mphamvu yakula pang'onopang'ono, makamaka kupanga ikuluikulu ya Longbai Gulu kolorayidi titaniyamu woipa, kusintha mkulu wa titaniyamu woipa ndi nkhani ya zinthu zakunja ndi zinthu zakunja - wosweka ndi zinthu zakunja ndi zinthu zakunja. Titanium dioxide ya m'nyumba yakhala ikuchitika." Anatero Shao Huiwen, wothirira ndemanga wamkulu pamsika.
Mphamvu ya chlorination process ikupitilira kukula
"Zaka zisanu zapitazo, mankhwala a chlorination titanium dioxide amangopanga 3.6% yokha ya zinthu zapakhomo, ndipo kapangidwe ka mafakitale kunali kosagwirizana." Oposa 90% ya zoweta mkulu-mapeto ntchito titaniyamu woipa amadalira kunja, mtengo ndi za 50% okwera mtengo kuposa zoweta ambiri titaniyamu woipa. Zogulitsa zapamwamba zimakhala ndi kudalira kwakukulu kwakunja, ndipo palibe mphamvu yolankhulirana m'mafakitale pazinthu za chlorinated titanium dioxide, zomwe zimalepheretsanso kusintha kwapamwamba komanso kukweza makampani aku China titanium dioxide. " Adatero Benliu.
Ziwerengero za kasitomu zikuwonetsa kuti m'gawo loyamba la 2023, kutulutsa kwa titaniyamu ku China kudakwera matani pafupifupi 13,200, kutsika ndi 64.25% pachaka; Kuchuluka kwa katundu wotumizidwa kunja kunali pafupifupi matani 437,100, kuwonjezeka kwa 12.65%. Malinga ndi kafukufuku wina, China titaniyamu woipa kupanga mphamvu mu 2022 ndi 4.7 miliyoni matani, kunja ndi pansi 43% kuchokera 2017, ndi kunja ndi 290% kuchokera 2012. zinthu zotsika mtengo zochokera kunja.” Woyang'anira bizinesi yopangira zokutira zapakhomo adatero.
Malinga ndi He Benliu, njira yaikulu ya titaniyamu woipa imagawidwa mu njira ya sulfuric acid, njira ya chlorination ndi njira ya hydrochloric acid, yomwe ndondomeko ya chlorination ndi yaifupi, yosavuta yowonjezera mphamvu yopangira, kuchuluka kwa makina opitirirabe, kugwiritsa ntchito mphamvu zochepa, zochepa "zinyalala zitatu" zotulutsa mpweya, zimatha kupeza mankhwala apamwamba kwambiri, ndiye njira yaikulu yopangira titaniyamu. Padziko lonse chlorination titaniyamu woipa ndi sulfuric asidi titaniyamu woipa kupanga mphamvu chiŵerengero cha za 6:4, mu Europe ndi United States, chiwerengero cha chlorination ndi apamwamba, chiwerengero cha China chakwera 3:7, kukonzekera tsogolo la chlorination titaniyamu woipa kotunga kupereŵera zinthu zidzapitiriza kukhala bwino.
Chlorination imalembedwa m'gulu lolimbikitsidwa
"Industrial dongosolo Adjustment Guide Guide Catalogue" lofalitsidwa ndi National Development and Reform Commission kutchulidwa kupanga chlorinated titaniyamu woipa mu gulu analimbikitsa, pamene kuchepetsa latsopano sanali coproduction wa sulfuric asidi titaniyamu woipa, amene wakhala mwayi kwa kusintha ndi kukulitsa mabizinezi titaniyamu woipa, kuyambira pamenepo zoweta anayamba kuonjezera zoweta titaniyamu chitukuko cha chlorine chitukuko cha chitukuko cha sayansi ndi kafukufuku. titaniyamu dioxide.
Patapita zaka kafukufuku luso, kuthetsa mavuto angapo mu mankhwala enaake titaniyamu woipa, Longbai Gulu apanga angapo apamwamba mndandanda wa mankhwala enaake mankhwala titaniyamu woipa wa mankhwala enaake wa mankhwala enaake, ntchito yonse yafika pa mlingo mayiko apamwamba, ntchito zina zafika pa mlingo mayiko kutsogolera. Ndife woyamba bwino nzeru ntchito yaikulu otentha chlorination titaniyamu woipa luso mabizinezi luso, mchitidwe watsimikiziranso kuti chlorination titaniyamu woipa luso kwambiri wobiriwira ndi zachilengedwe, zinyalala slag mulu katundu wake kuposa njira sulfuric acid kuchepetsa kuposa 90%, mabuku mphamvu kupulumutsa mpaka 30%, kupulumutsa madzi, kubweretsa katundu, muyezo 50 ntchito kwambiri kukumana ndi chilengedwe, 50% kupulumutsa, kubweretsa katundu ndi phindu lalikulu. adagwa swoop, ulamuliro wakunja pamsika wapamwamba wasweka, ndipo zogulitsa zadziwika ndi msika.
Ndi kupanga motsatizana wa ntchito zatsopano zoweta chlorinated titaniyamu woipa, mphamvu yake yopanga yafika pafupifupi matani miliyoni 1.08 ndi 2022, mlandu okwana mphamvu zoweta wakwera kuchokera 3.6% zaka zisanu zapitazo kuposa 22%, kuchepetsa kwambiri kudalira kunja kwa chlorinated titaniyamu woipa, ndi msika chuma mwayi wayamba kuonekera.
Okhala m'makampani amakhulupirira kuti potengera zomwe zikuchitika pakugwiritsa ntchito titaniyamu woipa kwambiri, komanso momwe zimakhalira komanso momwe makampani akunyumba amagwirira ntchito, kusintha kwa titaniyamu woipa ku China kwayamba kusokoneza masewerawa. Akuti m'madipatimenti aboma ndi mafakitale akuyenera kukulitsa chidwi ndi chitsogozo chakukonzekera kwa polojekiti ya chlorination, komanso mabizinesi akuyenera kuyang'aniridwa, kusiya ndalama za polojekiti ndikukonzekera njira zobwerera m'mbuyo ndi zinthu zobwerera m'mbuyo, ndikuyang'ana pakupanga ndi kugwiritsa ntchito zinthu zapamwamba kwambiri kuti apewe chiopsezo cha zinthu zotsika kwambiri.
