Imakethe ye-titanium dioxide eshisayo iminyaka eminingi iqhubekile nokupholisa kusukela engxenyeni yesibili yonyaka odlule, futhi intengo iye yehla kancane kancane. Kuze kube manje, amanani ahlukahlukene e-titanium dioxide ehle ngaphezu kuka-20%. Kodwa-ke, njengomkhiqizo osezingeni eliphezulu embonini ye-titanium dioxide, inqubo ye-chlorination titanium dioxide isaqinile.
“I-chlorination titanium dioxide nayo iyindlela yokuthuthukiswa kokuguqulwa okuphezulu kwemboni ye-titanium dioxide yaseShayina. Ekuhlinzekweni kwemakethe, ekuthuthukisweni kwezobuchwepheshe, izinzuzo ezihamba phambili nezinye, eminyakeni yamuva nje, amandla okukhiqizwa kwe-titanium dioxide ye-chloride yasekhaya akhule kancane kancane, ikakhulukazi ukukhiqizwa okukhulu kwemishini ye-titanium dioxide ye-chloride ye-Longbai Group kuphule isimo sokuthi imikhiqizo ephezulu ingaphansi kwamazwe angaphandle, futhi ukuguqulwa okuphezulu kwe-titanium dioxide yasekhaya bekulokhu kusendleleni.” Kusho uShao Huiwen, umhlaziyi omkhulu wemakethe.
Amandla enqubo yokufaka i-chlorine ayaqhubeka nokukhula
“Eminyakeni emihlanu edlule, imikhiqizo ye-titanium dioxide equkethe i-chlorination yayibalelwa ku-3.6% kuphela womkhiqizo wasekhaya, kanti isakhiwo sezimboni sasingalingani kakhulu.” Ngaphezu kuka-90% wokusetshenziswa kwe-titanium dioxide yasekhaya okuphezulu kuncike ekungenisweni kwamanye amazwe, intengo ibiza cishe ngo-50% kune-titanium dioxide ejwayelekile yasekhaya. Imikhiqizo ephezulu inezinga elikhulu lokuncika kwangaphandle, futhi akukho mandla okuxhumana embonini emikhiqizweni ye-titanium dioxide equkethe i-chlorinated, okubuye kube yimbangela yokuguqulwa okuphezulu kanye nokuthuthukiswa kwemboni ye-titanium dioxide yaseShayina.” UBenliu uthe.
Izibalo zentela zibonisa ukuthi kwikota yokuqala ka-2023, ukungeniswa kwe-titanium dioxide eShayina kwaqoqa cishe amathani ayi-13,200, kwehle ngo-64.25% unyaka nonyaka; Umthamo wokuthunyelwa kwamanye amazwe oqongelelekayo wawungamathani angaba ngu-437,100, ukwanda ngo-12.65%. Ngokusho kolunye ulwazi, umthamo wokukhiqiza i-titanium dioxide eShayina ngo-2022 ungamathani ayizigidi ezingu-4.7, ukungeniswa kwehle ngo-43% kusukela ngo-2017, kanti ukuthunyelwa kwamanye amazwe kukhuphuke ngo-290% kusukela ngo-2012. “Eminyakeni yamuva nje, ukungeniswa kwe-titanium dioxide yasekhaya kwehlile futhi umthamo wokuthunyelwa kwamanye amazwe ukhuphukile, ngoba ukwanda okusheshayo kwamandla okukhiqiza i-chloride titanium dioxide yamabhizinisi ahamba phambili asekhaya kunciphise ngempumelelo ukuncika emikhiqizweni ephezulu engenisiwe.” Umuntu ophethe ibhizinisi lokumboza lasekhaya uthe.
Ngokusho kukaHe Benliu, inqubo eyinhloko ye-titanium dioxide ihlukaniswe ngendlela ye-sulfuric acid, indlela ye-chlorination kanye nendlela ye-hydrochloric acid, lapho inqubo ye-chlorination imfushane, kulula ukwandisa umthamo wokukhiqiza, izinga eliphezulu lokuzenzakalela okuqhubekayo, ukusetshenziswa kwamandla okuphansi, ukukhishwa okuncane "kwemfucuza emithathu", kungathola imikhiqizo esezingeni eliphezulu, inqubo eyinhloko yokucindezela imboni ye-titanium dioxide. Isilinganiso somthamo wokukhiqiza we-chlorination titanium dioxide emhlabeni wonke kanye ne-sulfuric acid titanium dioxide esingaba ngu-6:4, eYurophu nase-United States, isilinganiso se-chlorination siphezulu, isilinganiso saseShayina sikhuphukele ku-3:7, ukulungiswa kwesikhathi esizayo kwe-chlorination titanium dioxide isimo sokuntuleka kokunikezwa sizoqhubeka nokuthuthukiswa.
Ukufakwa kwe-chlorine kufakwe ohlwini lwezigaba ezikhuthazwayo
I-“Industrial structure Adjustment Guidance Catalog” ekhishwe yiNational Development and Reform Commission ibhale ukukhiqizwa kwe-chlorine titanium dioxide esigabeni esikhuthazwayo, ngenkathi inciphisa ukungakhiqizwa kabusha kwe-sulfuric acid titanium dioxide, okuye kwaba yithuba lokuguqulwa nokuthuthukiswa kwamabhizinisi e-titanium dioxide, kusukela ngaleso sikhathi amabhizinisi asekhaya e-titanium dioxide aqala ukwandisa ucwaningo nentuthuko kanye nokutshalwa kwezimali ocwaningweni kubuchwepheshe bokukhiqiza i-chlorine titanium dioxide.
Ngemva kweminyaka eminingi yocwaningo lobuchwepheshe, ukuze kuxazululwe izinkinga eziningi ku-chloride titanium dioxide, i-Longbai Group isungule uchungechunge oluphezulu lwemikhiqizo ye-titanium dioxide ye-chloride ephezulu, ukusebenza okuphelele sekufinyelele ezingeni eliphezulu lamazwe ngamazwe, ukusebenza okuthile sekufinyelele ezingeni eliphambili lamazwe ngamazwe. Siyisicelo sokuqala esiphumelelayo sobuchwepheshe be-chlorination titanium dioxide ebanzi, umkhuba uphinde waqinisekisa ukuthi ubuchwepheshe be-chlorination titanium dioxide buluhlaza kakhulu futhi bunobungani nemvelo, isitokwe saso se-slag pile kunendlela ye-sulfuric acid yokunciphisa ngaphezu kwama-90%, ukonga amandla okuphelele kufika kuma-30%, ukonga amanzi kufika kuma-50%, izinzuzo zemvelo zibaluleke kakhulu, kanye nokusebenza komkhiqizo ukuhlangabezana namazinga okungenisa, Ngesikhathi esisodwa, ukuzimela kwamanye amazwe emakethe ephezulu sekuphukile, futhi imikhiqizo iqashelwe yimakethe.
Ngokukhiqizwa okulandelanayo kwamaphrojekthi amasha e-titanium dioxide akhiqizwe nge-chlorine, amandla ayo okukhiqiza afinyelele cishe amathani ayizigidi eziyi-1.08 ngo-2022, okubalwa amandla okukhiqiza akhiqizwe ngaphakathi akhuphuke kusuka ku-3.6% eminyakeni emihlanu edlule aya ngaphezu kwama-22%, okunciphisa kakhulu ukuncika kwangaphandle kwe-titanium dioxide ekhiqizwe nge-chlorine, futhi inzuzo yokutholakala kwemakethe isiqalile ukuvela.
Abantu abangaphakathi embonini bakholelwa ukuthi ngokusekelwe ekuthuthukisweni kokusetshenziswa kwe-titanium dioxide ephezulu, kanye nokwakheka kwamanje kanye nesimo samanje semboni yasekhaya, ukuguqulwa kwe-titanium dioxide ephezulu yaseShayina sekuqalile ukuqeda umdlalo. Kuphakanyiswa ukuthi iminyango kahulumeni efanele kanye nezimboni kufanele kwandise ukunaka kanye nesiqondiso sokuhlela iphrojekthi ye-chlorination, kanye namabhizinisi kufanele nawo aqondiswe, ayeke ukutshalwa kwezimali kwephrojekthi kanye nokuhlela izinqubo ezingemuva kanye nemikhiqizo engemuva, futhi agxile ekuthuthukisweni nasekusetshenzisweni kwemikhiqizo ephezulu ukuze agweme ingozi yemikhiqizo ephansi kakhulu.
