Lub lag luam titanium dioxide kub tau ntau xyoo tau txuas ntxiv txias txij li ib nrab xyoo tas los, thiab tus nqi tau maj mam poob qis. Txog rau tam sim no, ntau yam nqi titanium dioxide poob ntau dua 20%. Txawm li cas los xij, ua cov khoom lag luam siab hauv kev lag luam titanium dioxide, cov txheej txheem chlorination titanium dioxide tseem muaj zog.
"Kev siv chlorination titanium dioxide kuj yog qhov kev hloov pauv ntawm kev lag luam titanium dioxide hauv Suav teb. Hauv kev muab khoom lag luam, kev tsim kho tshiab, kev coj ua thiab lwm yam zoo, nyob rau xyoo tas los no, lub peev xwm tsim khoom hauv tsev chloride titanium dioxide tau loj hlob tas li, tshwj xeeb tshaj yog kev tsim khoom loj ntawm Longbai Group chloride titanium dioxide khoom siv tau rhuav tshem qhov xwm txheej uas cov khoom lag luam siab kawg raug rau cov teb chaws txawv teb chaws, thiab kev hloov pauv siab kawg ntawm titanium dioxide hauv tsev tau nyob ntawm txoj kev." Shao Huiwen, tus kws tshaj lij kev lag luam laus hais.
Lub peev xwm ntawm cov txheej txheem chlorination txuas ntxiv mus loj hlob
"Tsib xyoos dhau los, cov khoom siv chlorine titanium dioxide tsuas yog 3.6% ntawm cov khoom tsim tawm hauv tsev, thiab cov qauv kev lag luam tsis sib npaug zoo." Ntau tshaj 90% ntawm cov ntawv thov high-end hauv tsev ntawm titanium dioxide vam khom kev xa khoom tuaj, tus nqi yog kwv yees li 50% kim dua li cov khoom siv hauv tsev dav dav titanium dioxide. Cov khoom lag luam siab kawg muaj kev vam khom sab nraud ntau, thiab tsis muaj lub zog sib tham hauv kev lag luam ntawm cov khoom siv chlorinated titanium dioxide, uas kuj yog qhov tsis zoo ntawm kev hloov pauv siab thiab kev txhim kho ntawm Tuam Tshoj txoj kev lag luam titanium dioxide. "Nws Benliu hais.
Cov ntaub ntawv kev lis kev cai qhia tau tias nyob rau hauv peb lub hlis twg ntawm xyoo 2023, Tuam Tshoj cov titanium dioxide xa tuaj tau sau txog li 13,200 tons, poob 64.25% xyoo-rau-xyoo; Lub ntim xa tawm tag nrho yog li 437,100 tons, nce 12.65%. Raws li lwm cov ntaub ntawv, Tuam Tshoj lub peev xwm tsim titanium dioxide hauv xyoo 2022 yog 4.7 lab tons, kev xa khoom poob qis 43% los ntawm xyoo 2017, thiab kev xa khoom nce 290% los ntawm xyoo 2012. "Hauv xyoo tas los no, kev xa khoom titanium dioxide hauv tsev tau poob qis thiab qhov ntim xa khoom tau nce, vim tias kev nthuav dav sai ntawm cov tuam txhab ua lag luam hauv tsev chloride titanium dioxide tsim peev xwm tau ua rau txo qis kev vam khom rau cov khoom lag luam siab." Tus neeg saib xyuas kev lag luam hauv tsev hais.
Raws li He Benliu, cov txheej txheem tseem ceeb ntawm titanium dioxide yog muab faib ua sulfuric acid txoj kev, chlorination txoj kev thiab hydrochloric acid txoj kev, uas cov txheej txheem chlorination luv luv, yooj yim los nthuav dav peev xwm tsim khoom, qib siab ntawm kev ua haujlwm tas mus li, kev siv hluav taws xob tsawg, tsawg dua "peb pov tseg" emissions, tuaj yeem tau txais cov khoom zoo, yog cov txheej txheem tseem ceeb ntawm kev lag luam titanium dioxide. Lub ntiaj teb chlorination titanium dioxide thiab sulfuric acid titanium dioxide muaj peev xwm tsim khoom piv ntawm kwv yees li 6: 4, hauv Tebchaws Europe thiab Tebchaws Meskas, qhov feem pua ntawm chlorination siab dua, Tuam Tshoj qhov feem pua tau nce mus txog 3: 7, kev npaj yav tom ntej ntawm chlorination titanium dioxide tsis txaus qhov xwm txheej yuav txuas ntxiv mus zoo dua.
Kev siv tshuaj chlorine tau teev nyob rau hauv pawg uas txhawb nqa
Daim ntawv teev cov lus qhia txog kev hloov kho cov qauv kev lag luam uas tau muab los ntawm National Development and Reform Commission tau teev cov kev tsim cov chlorinated titanium dioxide hauv pawg uas tau txhawb nqa, thaum txwv tsis pub muaj kev tsim cov sulfuric acid titanium dioxide tshiab, uas tau dhau los ua lub sijhawm rau kev hloov pauv thiab kev txhim kho ntawm cov tuam txhab titanium dioxide, txij thaum ntawd los cov tuam txhab titanium dioxide hauv tsev tau pib nce kev tshawb fawb thiab kev txhim kho thiab kev nqis peev hauv kev tshawb fawb hauv cov thev naus laus zis tsim cov chlorinated titanium dioxide.
Tom qab ntau xyoo ntawm kev tshawb fawb txog kev siv tshuab, los daws ntau yam teeb meem hauv chloride titanium dioxide, Longbai Group tau tsim ntau yam khoom zoo ntawm cov khoom siv chloride titanium dioxide, qhov kev ua tau zoo tag nrho tau mus txog qib siab thoob ntiaj teb, qee qhov kev ua tau zoo tau mus txog qib siab thoob ntiaj teb. Peb yog thawj qhov kev siv tshuab ua kom muaj kev vam meej ntawm cov tuam txhab ua lag luam chlorination titanium dioxide loj, kev xyaum kuj tau lees paub tias chlorination titanium dioxide thev naus laus zis yog ntsuab dua thiab zoo rau ib puag ncig, nws cov khib nyiab slag pawg khoom dua li txoj kev sulfuric acid kom txo tau ntau dua 90%, kev txuag hluav taws xob txog li 30%, kev txuag dej txog li 50%, cov txiaj ntsig ib puag ncig tseem ceeb heev, thiab kev ua tau zoo ntawm cov khoom kom ua tau raws li cov qauv ntshuam, Hauv ib qho kev poob qis, kev lag luam txawv teb chaws hauv kev lag luam siab tau tawg, thiab cov khoom tau lees paub los ntawm kev ua lag luam.
Nrog rau kev tsim cov haujlwm tshiab hauv tsev uas muaj chlorinated titanium dioxide, nws lub peev xwm tsim khoom tau txog li 1.08 lab tons los ntawm xyoo 2022, suav rau tag nrho cov peev xwm tsim khoom hauv tsev tau nce los ntawm 3.6% tsib xyoos dhau los mus rau ntau dua 22%, txo qhov kev vam khom sab nraud ntawm chlorinated titanium dioxide, thiab qhov zoo ntawm kev muab khoom lag luam tau pib tshwm sim.
Cov neeg ua lag luam ntseeg tias raws li kev txhim kho ntawm kev siv titanium dioxide siab heev, nrog rau qhov kev teeb tsa tam sim no thiab qhov xwm txheej ntawm kev lag luam hauv tsev, Tuam Tshoj txoj kev hloov pauv titanium dioxide siab heev tau pib ua rau qhov kev ua si tawg. Nws tau hais tias cov koom haum tsoomfwv thiab cov lag luam yuav tsum ua tib zoo saib xyuas thiab taw qhia txog kev npaj chlorination project, thiab cov lag luam kuj yuav tsum raug tsom mus rau, tso tseg kev nqis peev thiab kev npaj ntawm cov txheej txheem rov qab thiab cov khoom rov qab, thiab tsom mus rau kev txhim kho thiab kev siv cov khoom lag luam siab kom tsis txhob muaj kev pheej hmoo ntawm cov khoom qis dua.
