Imarike ye-titanium dioxide eshushu kangangeminyaka emininzi iqhubekile nokuphola ukusukela kwisiqingatha sesibini sonyaka ophelileyo, kwaye ixabiso liye lehla kancinci kancinci. Ukuza kuthi ga ngoku, amaxabiso e-titanium dioxide ahlukeneyo ehle ngaphezulu kwama-20%. Nangona kunjalo, njengemveliso ephezulu kushishino lwe-titanium dioxide, inkqubo ye-chlorination titanium dioxide isenamandla.
“I-chlorination titanium dioxide ikwayindlela yophuhliso lotshintsho oluphezulu kwishishini le-titanium dioxide laseTshayina. Kwimarike, impumelelo kwezobuchwepheshe, iingenelo eziphambili kunye nezinye, kwiminyaka yakutshanje, amandla emveliso ye-chloride titanium dioxide yasekhaya akhule ngokuthe chu, ingakumbi imveliso enkulu yezixhobo ze-titanium dioxide ze-Longbai Group chloride iphule imeko yokuba iimveliso eziphezulu zixhomekeke kumazwe angaphandle, kwaye utshintsho oluphezulu lwe-titanium dioxide yasekhaya luye lwaqhubeka.” utshilo uShao Huiwen, umhlalutyi omkhulu wemarike.
Umthamo wenkqubo ye-chlorination uyaqhubeka nokukhula
“Kwiminyaka emihlanu eyadlulayo, iimveliso ze-titanium dioxide ezisebenzisa i-chlorination zaziyi-3.6% kuphela yemveliso yasekhaya, kwaye ulwakhiwo lwemizi-mveliso lwalungalingani ngokupheleleyo.” Ngaphezulu kwe-90% yezicelo zasekhaya eziphezulu ze-titanium dioxide zixhomekeke ekungenisweni kwamanye amazwe, ixabiso libiza malunga ne-50% ngaphezulu kune-titanium dioxide yasekhaya. Iimveliso eziphezulu zixhomekeke kakhulu ngaphandle, kwaye akukho mandla okuthetha ngeshishini kwiimveliso ze-titanium dioxide ezisebenzisa i-chlorinated, nto leyo ekwayingxaki yokuguqulwa okuphezulu kunye nokuphuculwa kweshishini le-titanium dioxide laseTshayina.” Utshilo uBenliu.
Izibalo zerhafu zibonisa ukuba kwikota yokuqala ka-2023, ukungeniswa kwe-titanium dioxide eTshayina kuqokelele malunga neetoni ezili-13,200, kwehle ngama-64.25% ngonyaka; Umthamo wokuthunyelwa kwamanye amazwe oqokelelweyo wawumalunga neetoni ezingama-437,100, ukwanda kwe-12.65%. Ngokwezinye iinkcukacha, amandla okuvelisa i-titanium dioxide eTshayina ngo-2022 yi-4.7 yezigidi zeetoni, ukungeniswa kwamanye amazwe kwehle ngama-43% ukusuka ngo-2017, kwaye ukuthunyelwa kwamanye amazwe kwenyuke ngama-290% ukusuka ngo-2012. “Kwiminyaka yakutshanje, ukungeniswa kwe-titanium dioxide yasekhaya kwehlile kwaye umthamo wokuthunyelwa kwamanye amazwe unyukile, kuba ukwanda ngokukhawuleza kwamandla okuvelisa i-chloride titanium dioxide yamashishini aphambili asekhaya kuye kwanciphisa ngempumelelo ukuxhomekeka kwiimveliso eziphezulu ezingenisiweyo.” Utshilo umntu ophethe ishishini lokugquma lasekhaya.
Ngokutsho kukaHe Benliu, inkqubo ephambili ye-titanium dioxide yahlulwe yaba yindlela ye-sulfuric acid, indlela ye-chlorination kunye nendlela ye-hydrochloric acid, apho inkqubo ye-chlorination imfutshane, kulula ukwandisa amandla emveliso, inqanaba eliphezulu lokuzenzekelayo okuqhubekayo, ukusetyenziswa kwamandla okuphantsi, ukukhutshwa okuncinci "kwenkunkuma ezintathu", kunokufumana iimveliso ezikumgangatho ophezulu, yinkqubo ephambili yokutyhala imboni ye-titanium dioxide. Umlinganiselo womthamo wemveliso ye-chlorination titanium dioxide kwihlabathi liphela kunye ne-sulfuric acid titanium dioxide malunga ne-6:4, eYurophu nase-United States, umlinganiselo we-chlorination uphezulu, umlinganiselo waseTshayina unyuke waya kwi-3:7, imeko yokunqongophala kobonelelo lwe-chlorination titanium dioxide iya kuqhubeka iphucuka.
Ukufakwa kwe-chlorine kudweliswe kudidi olukhuthazwayo
I-"Ikhathalogu yeSikhokelo soLungiso lweSimo seShishini" ekhutshwe yiKhomishini yoPhuhliso noHlaziyo yeSizwe idwelise ukuveliswa kwe-titanium dioxide ekhlohliweyo kudidi olukhuthazwayo, ngelixa ithintela ukungaveliswa kwakhona kwe-titanium dioxide ekhlohliweyo, eye yaba lithuba lokuguqulwa nokuphuculwa kwamashishini e-titanium dioxide, ukusukela ngoko amashishini e-titanium dioxide asekhaya aqala ukwandisa uphando nophuhliso kunye notyalo-mali lophando kubuchwepheshe bokuvelisa i-titanium dioxide ekhlohliweyo.
Emva kweminyaka yophando lobuchwephesha, ukusombulula iingxaki ezininzi kwi-chloride titanium dioxide, iLongbai Group iphuhlise uthotho lweemveliso ze-titanium dioxide ezikumgangatho ophezulu ze-chloride ephezulu, ukusebenza ngokubanzi kufikelele kwinqanaba eliphezulu lamazwe ngamazwe, ukusebenza okuthile kufikelele kwinqanaba eliphambili lamazwe ngamazwe. Siyisicelo sokuqala esiphumeleleyo sobuchule be-chlorination titanium dioxide ebilayo enkulu, kwaye i-practice ikwaqinisekisile ukuba iteknoloji ye-chlorination titanium dioxide iluhlaza ngakumbi kwaye inobuhlobo nokusingqongileyo, isitokhwe sayo se-slag pile kunendlela ye-sulfuric acid yokunciphisa ngaphezu kwe-90%, ukonga amandla okubanzi ukuya kuthi ga kwi-30%, ukonga amanzi ukuya kuthi ga kwi-50%, iingenelo zokusingqongileyo zibaluleke kakhulu, kwaye ukusebenza kwemveliso kuyahlangabezana nemigangatho yokungenisa, Ngesinye isihlandlo, ukuzimela kwamanye amazwe kwimarike ephezulu kuye kwaphulwa, kwaye iimveliso ziye zaqatshelwa yimarike.
Ngemveliso elandelelanayo yeeprojekthi ezintsha ze-titanium dioxide ezifakwe i-chlorine zasekhaya, amandla ayo okuvelisa afikelele kwiitoni ezimalunga ne-1.08 yezigidi ngo-2022, nto leyo ebangela ukuba amandla ayo okuvelisa anyuke ukusuka kwi-3.6% kwiminyaka emihlanu eyadlulayo ukuya ngaphezulu kwe-22%, nto leyo enciphisa kakhulu ukuxhomekeka kwangaphandle kwe-titanium dioxide efakwe i-chlorine, kwaye inzuzo yokubonelela ngemarike iqalile ukubonakala.
Abantu abangaphakathi kushishino bakholelwa ukuba ngokusekelwe kwindlela yophuhliso lokusetyenziswa kwe-titanium dioxide ephezulu, kunye nolwakhiwo lwangoku kunye nemeko ekhoyo kushishino lwasekhaya, utshintsho lwe-titanium dioxide ephezulu eTshayina luqalile ukuphazamisa umdlalo. Kucetyiswa ukuba amasebe karhulumente afanelekileyo kunye namashishini kufuneka andise ingqalelo kunye nesikhokelo sokucwangcisa iprojekthi ye-chlorination, kwaye amashishini nawo kufuneka ajoliswe, ayeke utyalo-mali lweprojekthi kunye nokucwangciswa kweenkqubo ezingasemva kunye neemveliso ezingasemva, kwaye agxile kuphuhliso kunye nokusetyenziswa kweemveliso eziphezulu ukuze kuthintelwe umngcipheko weemveliso ezisezantsi kakhulu.
