Phetoho e phahameng ea titanium dioxide e butsoe

Mmaraka o chesang oa titanium dioxide ka lilemo tse ngata o ntse o tsoela pele ho pholile ho tloha karolong ea bobeli ea selemo se fetileng, 'me theko e theohile butle-butle. Ho fihlela joale, litheko tse fapaneng tsa titanium dioxide li theohile ka ho feta 20%. Leha ho le joalo, e le sehlahisoa sa maemo a holimo indastering ea titanium dioxide, ts'ebetso ea chlorination titanium dioxide e ntse e le matla.

“Chlorination titanium dioxide le yona ke mokgwa wa ntshetsopele wa phetoho e phahameng ya indasteri ya titanium dioxide ya China. Kabong ya mmaraka, diphetoho tsa theknoloji, melemo e etellang pele le e meng, dilemong tsa morao tjena, bokgoni ba tlhahiso ya titanium dioxide ya chloride ya lapeng bo hodile butle-butle, haholoholo tlhahiso e kgolo ya disebediswa tsa titanium dioxide tsa Longbai Group chloride e sentse boemo ba hore dihlahiswa tse phahameng di ka tlasa dinaha tse ding, mme phetoho e phahameng ya titanium dioxide ya lapeng e bile tseleng.” Ho boletse Shao Huiwen, mohlahlobi e moholo wa mmaraka.

Bokgoni ba ts'ebetso ea chlorination bo ntse bo hola

“Lilemong tse hlano tse fetileng, lihlahisoa tsa titanium dioxide tse nang le chlorination li ne li etsa 3.6% feela ea tlhahiso ea malapeng, 'me sebopeho sa indasteri se ne se sa leka-lekanngoa haholo.” Ho feta 90% ea lits'ebetso tsa maemo a holimo tsa titanium dioxide tsa malapeng li itšetlehile ka thepa e tsoang kantle ho naha, theko e bitsa chelete e ka bang 50% ho feta titanium dioxide ea lehae. Lihlahisoa tsa maemo a holimo li na le tekanyo e kholo ea ho itšetleha ka ntle, 'me ha ho na matla a puisano ea indasteri lihlahisoa tsa titanium dioxide tse nang le chlorinated, e leng eona e bakang phetoho e phahameng le ntlafatso ea indasteri ea titanium dioxide ea Chaena.” O boletse joalo Benliu.

Lipalopalo tsa Lekgetho di bontsha hore kotara ya pele ya 2023, thepa e tswang China e nang le titanium dioxide e ile ya bokellana ka ditone tse ka bang 13,200, e theohile ka 64.25% selemo le selemo; Bophahamo ba thepa e romellwang kantle ho naha bo ne bo ka ba ditone tse 437,100, e leng keketseho ya 12.65%. Ho ya ka tlhahisoleseding e nngwe, bokgoni ba tlhahiso ya titanium dioxide ya China ka 2022 ke ditone tse dimilione tse 4.7, thepa e tswang kantle ho naha e theohile ka 43% ho tloha ka 2017, mme thepa e tswang kantle ho naha e nyolohile ka 290% ho tloha ka 2012. “Dilemong tsa morao tjena, thepa e tswang kantle ho naha e nang le titanium dioxide ya lehae e theohile mme palo ya thepa e romellwang kantle ho naha e eketsehile, hobane katoloso e potlakileng ya bokgoni ba tlhahiso ya chloride titanium dioxide ya dikgwebo tse etellang pele malapeng e fokoditse ho itshetleha ka dihlahiswa tse tswang kantle ho naha.” Motho ya ikarabellang bakeng sa kgwebo ya ho roka ya lehae o boletse jwalo.

Ho ea ka He Benliu, ts'ebetso e kholo ea titanium dioxide e arotsoe ka mokhoa oa sulfuric acid, mokhoa oa chlorination le mokhoa oa hydrochloric acid, oo ts'ebetso ea chlorination e leng khutšoanyane, e bonolo ho atolosa bokhoni ba tlhahiso, boemo bo phahameng ba othomathike bo tsoelang pele, tšebeliso e tlase ea matla, mesi e fokolang ea "litšila tse tharo", e ka fumanang lihlahisoa tsa boleng bo holimo, ke ts'ebetso e ka sehloohong ea indasteri ea titanium dioxide.

Kamora lilemo tsa lipatlisiso tsa botekgeniki, ho rarolla mathata a 'maloa ka chloride titanium dioxide, Longbai Group e thehile letoto la lihlahisoa tse ngata tsa boleng bo holimo tsa chloride titanium dioxide, ts'ebetso ka kakaretso e fihlile boemong bo tsoetseng pele ba machaba, ts'ebetso e itseng e fihlile boemong bo etellang pele ba machaba.
