Msika wotentha wa titanium dioxide kwa zaka zambiri wakhala ukutsika kuyambira theka lachiwiri la chaka chatha, ndipo mtengo wake watsika pang'onopang'ono. Mpaka pano, mitengo yosiyanasiyana ya titanium dioxide yatsika ndi zoposa 20%. Komabe, monga chinthu chapamwamba kwambiri mumakampani opanga titanium dioxide, njira ya chlorination ya titanium dioxide ikadali yolimba.
"Chlorination titanium dioxide ndi njira yopititsira patsogolo kusintha kwapamwamba kwa makampani aku China a titanium dioxide. Pakugulitsa, kupita patsogolo kwaukadaulo, zabwino zotsogola ndi zina, m'zaka zaposachedwa, mphamvu yopanga titanium dioxide ya chloride yapakhomo yakula pang'onopang'ono, makamaka kupanga kwakukulu kwa zida za titanium dioxide za Longbai Group chloride kwathetsa vutoli loti zinthu zapamwamba zimayendetsedwa ndi mayiko akunja, ndipo kusintha kwakukulu kwa titanium dioxide yapakhomo kwakhala kukuchitika." Anatero Shao Huiwen, katswiri wamkulu wa ndemanga pamsika.
Mphamvu ya njira yopangira chlorine ikupitilira kukula
"Zaka zisanu zapitazo, zinthu zopangidwa ndi titanium dioxide zopangidwa ndi chlorination zinkangopanga 3.6% yokha ya zinthu zopangidwa m'nyumba, ndipo kapangidwe ka mafakitale kanali kosayenera kwambiri." Kuposa 90% ya ntchito zapamwamba za titanium dioxide m'nyumba zimadalira zinthu zochokera kunja, mtengo wake ndi wokwera mtengo pafupifupi 50% kuposa titanium dioxide wamba m'nyumba. Zinthu zapamwamba zimadalira kwambiri zakunja, ndipo palibe mphamvu yolankhulana ndi mafakitale pazinthu zopangidwa ndi titanium dioxide zopangidwa ndi chlorinated, zomwe ndi vuto la kusintha kwakukulu ndi kukweza makampani opanga titanium dioxide ku China." Anatero Benliu.
Ziwerengero za misonkho zikusonyeza kuti mu kotala yoyamba ya 2023, kutumizidwa kwa titanium dioxide ku China kunasonkhanitsa matani pafupifupi 13,200, kutsika ndi 64.25% pachaka; Kuchuluka kwa kutumiza kunja kunali pafupifupi matani 437,100, kuwonjezeka kwa 12.65%. Malinga ndi deta ina, mphamvu yopanga titanium dioxide ku China mu 2022 ndi matani 4.7 miliyoni, kutumizidwa kunja kwatsika ndi 43% poyerekeza ndi 2017, ndipo kutumizidwa kunja kwakwera ndi 290% poyerekeza ndi 2012. "M'zaka zaposachedwa, kutumizidwa kwa titanium dioxide m'nyumba kwatsika ndipo kuchuluka kwa kutumiza kunja kwawonjezeka, chifukwa kukulirakulira mwachangu kwa mphamvu yopanga chloride titanium dioxide m'mabizinesi akuluakulu am'nyumba kwachepetsa kudalira zinthu zapamwamba zochokera kunja." Munthu woyang'anira kampani yopaka utoto m'nyumba adatero.
Malinga ndi He Benliu, njira yayikulu ya titanium dioxide imagawidwa m'njira ya sulfuric acid, njira ya chlorination ndi njira ya hydrochloric acid, yomwe njira ya chlorination ndi yochepa, yosavuta kukulitsa mphamvu zopangira, digiri yayikulu ya automation yopitilira, kugwiritsa ntchito mphamvu zochepa, kutulutsa "zinyalala zitatu", kumatha kupeza zinthu zapamwamba, ndiye njira yayikulu yolimbikitsira makampani a titanium dioxide. Chiŵerengero cha mphamvu yopanga titanium dioxide padziko lonse lapansi cha chlorination ndi sulfuric acid titanium dioxide cha pafupifupi 6:4, ku Europe ndi United States, chiwerengero cha chlorination ndi chachikulu, chiwerengero cha China chakwera kufika pa 3:7, kukonzekera mtsogolo kwa chlorination titanium dioxide kusowa kwa zinthu kudzapitirirabe kukonzedwa.
Kuthira mankhwala a chlorine m'gulu la mankhwala omwe akulimbikitsidwa
Kabukhu ka “Industrial structure Adjustment Guidance Catalog” komwe kanatulutsidwa ndi National Development and Reform Commission kanalemba za kupanga titanium dioxide yokhala ndi chlorinated mu gulu lomwe likulimbikitsidwa, pomwe kamachepetsa kupanga titanium dioxide yokhala ndi sulfuric acid, komwe kwakhala mwayi wosintha ndi kukweza mabizinesi a titanium dioxide, kuyambira pamenepo mabizinesi akunyumba a titanium dioxide adayamba kuwonjezera kafukufuku ndi chitukuko ndi ndalama zofufuzira muukadaulo wopanga titanium dioxide yokhala ndi chlorinated.
Pambuyo pa zaka zambiri za kafukufuku waukadaulo, kuti athetse mavuto angapo mu chloride titanium dioxide, Longbai Group yapanga mndandanda wazinthu zapamwamba kwambiri za chloride titanium dioxide, magwiridwe antchito onse afika pamlingo wapamwamba wapadziko lonse lapansi, magwiridwe antchito ena afika pamlingo wotsogola wapadziko lonse lapansi. Ndife oyamba kugwiritsa ntchito bwino zatsopano zamabizinesi akuluakulu aukadaulo wa chlorination titanium dioxide, machitidwe atsimikiziranso kuti ukadaulo wa chlorination titanium dioxide ndi wobiriwira komanso wochezeka, njira yake yochepetsera zinyalala kuposa sulfuric acid ndi kuchepetsa zoposa 90%, kusunga mphamvu kwathunthu mpaka 30%, kusunga madzi mpaka 50%, ubwino wa chilengedwe ndi wofunikira kwambiri, ndipo magwiridwe antchito azinthu akwaniritsa miyezo yolowera kunja. Munthawi imodzi, monopoly yakunja pamsika wapamwamba yasweka, ndipo malonda azindikirika ndi msika.
Ndi kupanga mapulojekiti atsopano a titanium dioxide okhala ndi chlorine m'nyumba, mphamvu yake yopangira yafika pafupifupi matani 1.08 miliyoni pofika chaka cha 2022, zomwe zikutanthauza kuti mphamvu yonse yopangira m'nyumba yakwera kuchoka pa 3.6% zaka zisanu zapitazo kufika pa 22%, zomwe zachepetsa kwambiri kudalira kwakunja kwa titanium dioxide yokhala ndi chlorine, ndipo mwayi wopeza zinthu pamsika wayamba kuwonekera.
Akatswiri amakampani amakhulupirira kuti kutengera njira yopangira titanium dioxide yapamwamba, komanso momwe makampani akumagwirira ntchito komanso momwe zinthu zilili masiku ano, kusintha kwa titanium dioxide yapamwamba ku China kwayamba kusokoneza zinthu. Akuti madipatimenti ndi mafakitale oyenerera ayenera kuwonjezera chidwi ndi chitsogozo pakukonzekera mapulojekiti a chlorination, ndipo mabizinesi nawonso ayenera kuyang'aniridwa, kusiya ndalama zomwe amaika pa projekitiyi ndikukonzekera njira zobwerera m'mbuyo ndi zinthu zobwerera m'mbuyo, ndikuyang'ana kwambiri pakupanga ndi kugwiritsa ntchito zinthu zapamwamba kuti apewe chiopsezo cha zinthu zotsika kwambiri.
