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 titanium dioxide ndiyenso njira yopititsira patsogolo kusinthika kwamakampani aku China a titanium dioxide.Mu msika, zokolola zamakono, kutsogolera ndi ubwino zina, m'zaka zaposachedwapa, zoweta kolorayidi titaniyamu woipa kupanga mphamvu wakula pang'onopang'ono, makamaka kupanga yaikulu ya Longbai Gulu mankhwala titaniyamu titaniyamu zida wathyola zinthu kuti mkulu-mapeto mankhwala. akukhudzidwa ndi mayiko akunja, ndipo kusintha kwakukulu kwa titanium dioxide m'nyumba kwakhala panjira. "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 zidziwitso zina, mphamvu yaku China ya titanium dioxide mu 2022 ndi matani 4.7 miliyoni, zotuluka kunja zatsika ndi 43% kuchokera ku 2017, ndipo zotumiza kunja zakwera 290% kuyambira 2012. chawonjezeka, chifukwa kukwera msanga kwa mabizinesi otsogola amtundu wa chloride titanium dioxide wachepetsa kudalira zinthu zotsika mtengo zomwe zimatumizidwa 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 kukulitsa mphamvu yopangira, digiri yapamwamba yamagetsi osatha, mowa wochepa mphamvu, zocheperako "zitatu zinyalala" mpweya, akhoza kupeza mankhwala apamwamba, ndiye njira yaikulu kukankhira makampani titaniyamu woipa.Padziko lonse chlorination titaniyamu woipa ndi sulfuric asidi titaniyamu woipa kupanga mphamvu chiŵerengero cha za 6:4, ku Ulaya ndi United States, chiwerengero cha chlorination ndi apamwamba, chiwerengero cha China chakwera 3:7, tsogolo kukonzekera chlorination titaniyamu woipa kotunga. Kuperewera kupitilira kukonzedwa.
Chlorination imalembedwa m'gulu lolimbikitsidwa
Bungwe la "Industrial structure Adjustment Guidance Catalogue" loperekedwa ndi National Development and Reform Commission lidalemba kupanga chlorinated titaniyamu woipa m'gulu lolimbikitsidwa, ndikuletsa kusapangana kwatsopano kwa sulfuric acid titanium dioxide, yomwe yakhala mwayi wosintha ndi kusintha. kukweza titaniyamu woipa mabizinesi, kuyambira pamenepo zoweta titaniyamu woipa mabizinezi anayamba kuonjezera kafukufuku ndi chitukuko ndi kafukufuku ndalama kupanga luso chlorinated titaniyamu woipa.
Patapita zaka kafukufuku luso, kuthetsa angapo mavuto kolorayidi titaniyamu woipa, Longbai Gulu apanga angapo apamwamba mndandanda wa mankhwala enaake mankhwala titaniyamu woipa wa mankhwala enaake, ntchito wonse wafika pa mlingo mayiko apamwamba, ntchito zina adafika pamlingo wotsogola padziko lonse lapansi.Ndife woyamba bwino nzeru ntchito yaikulu yowira chlorination titaniyamu woipa luso mabizinezi, mchitidwe watsimikiziranso kuti chlorination titaniyamu woipa luso ndi wobiriwira ndi zachilengedwe, zinyalala zake slag mulu katundu kuposa njira sulfuric acid kuchepetsa kuposa 90%, kupulumutsa mphamvu zonse mpaka 30%, kupulumutsa madzi mpaka 50%, zopindulitsa zachilengedwe ndizofunika kwambiri, komanso magwiridwe antchito kuti akwaniritse miyezo yolowera kunja, M'modzi mwawo adagwa, kulamulira kwakunja pamsika wokwera kwambiri kwasweka, ndipo zopangidwa 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 zoweta mphamvu wakwera kuchokera 3.6% zaka zisanu zapitazo kuposa 22%, kuchepetsa kwambiri kudalira kunja. wa chlorinated titanium dioxide, ndipo phindu la msika 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 madipatimenti aboma ndi mafakitale oyenerera awonjezere chidwi ndi chitsogozo chakukonzekera kwa polojekiti ya chlorination, ndipo mabizinesi ayeneranso kuyang'ana, kusiya kugulitsa ntchito ndikukonzekera njira zobwerera m'mbuyo ndi zinthu zakumbuyo, ndikuyang'ana pa chitukuko ndi kugwiritsa ntchito zida zapamwamba kwambiri. mapeto kuti apewe chiopsezo cha mankhwala owonjezera otsika.
