Musika we titanium dioxide unopisa kwemakore mazhinji wakaramba uchitonhora kubva muhafu yechipiri yegore rapfuura, uye mutengo wacho wakaramba uchidzikira zvishoma nezvishoma. Kusvika pari zvino, mitengo yakasiyana-siyana ye titanium dioxide yakaderera neanopfuura 20%. Zvisinei, sechigadzirwa chepamusoro-soro muindasitiri ye titanium dioxide, nzira ye chlorination titanium dioxide ichiri yakasimba.
"Chlorination titanium dioxide ndiyo nzira yekuvandudza shanduko yepamusoro-soro yeindasitiri yetitanium dioxide muChina. Mumusika, kubudirira kwetekinoroji, kutungamira nezvimwe zvakanakira, mumakore achangopfuura, kugona kwekugadzira titanium dioxide yechloride yemuno kwakawedzera zvishoma nezvishoma, kunyanya kugadzirwa kukuru kwemidziyo yetitanium dioxide yeLongbai Group chloride kwakaputsa mamiriro ezvinhu ekuti zvigadzirwa zvepamusoro-soro zvinotorwa nenyika dzekunze, uye shanduko yepamusoro-soro yetitanium dioxide yemuno yave iri munzira." akadaro Shao Huiwen, muongorori mukuru wemusika.
Kukwanisa kwekuita chlorination kuri kuramba kuchikura
"Makore mashanu apfuura, zvigadzirwa zve titanium dioxide zvinogadzirwa ne chlorination zvaingove 3.6% chete yekugadzirwa kwemuno, uye chimiro chemaindasitiri chakanga chisina kuenzana zvakanyanya." Zvinopfuura 90% zvekushandiswa kwepamusoro kwe titanium dioxide munyika zvinotsamira pakutengwa kwenyika, mutengo wacho unodhura ne50% kupfuura titanium dioxide yemuno. Zvigadzirwa zvepamusoro zvinotsamira zvakanyanya kunze, uye hapana simba rekutaura nezveindasitiri pazvigadzirwa zve titanium dioxide zvine chlorinated, izvo zviriwo dambudziko rekuchinja kwepamusoro uye kusimudzira indasitiri ye titanium dioxide yeChina." Iye Benliu akadaro.
Nhamba dzezvemitero dzinoratidza kuti muchikamu chekutanga chegore ra2023, kutengeswa kwetitanium dioxide muChina kwakaunganidza matani angangoita 13,200, kuderera ne64.25% gore negore; Huwandu hwezvinhu zvakatengeswa kunze kwenyika hwaive matani angangoita 437,100, kuwedzera kwe12.65%. Sekureva kwemamwe mashoko, kugona kweChina kugadzira titanium dioxide muna 2022 i4.7 miriyoni matani, kutengeswa kunze kwenyika kwaderera ne43% kubva muna 2017, uye kutengeswa kunze kwenyika kwakawedzera ne290% kubva muna 2012. "Mumakore achangopfuura, kutengeswa kwetitanium dioxide mudzimba kwaderera uye huwandu hwezvinhu zvakatengeswa kunze kwenyika hwakawedzera, nekuti kuwedzera nekukurumidza kwesimba rekugadzira chloride titanium dioxide mumakambani makuru emudzimba kwakaderedza kuvimba nezvigadzirwa zvepamusoro zvinotengeswa kunze kwenyika." Munhu anotungamira kambani yekupenda yemudzimba akadaro.
Sekureva kwaHe Benliu, maitiro makuru e titanium dioxide akakamurwa kuita nzira ye sulfuric acid, nzira ye chlorination uye nzira ye hydrochloric acid, iyo nzira ye chlorination iri pfupi, iri nyore kuwedzera kugona kwekugadzira, mwero wepamusoro we automation inoenderera mberi, kushandiswa kwesimba kwakaderera, "marara matatu" mashoma, anogona kuwana zvigadzirwa zvemhando yepamusoro, ndiyo nzira huru yekusundidzira titanium dioxide indasitiri. Chiyero chepasi rose che chlorination titanium dioxide uye sulfuric acid titanium dioxide yekugadzira chiyero cheinenge 6:4, muEurope neUnited States, chikamu che chlorination chakakwira, chikamu cheChina chakakwira kusvika 3:7, kugadzirira kwe chlorination titanium dioxide supply kushomeka kucharamba kuchivandudzwa.
Kuisa chlorine muchikamu chinokurudzirwa
Kabhuku kanonzi "Industrial structure Adjustment Guidance Catalog" kakaburitswa neNational Development and Reform Commission kakaratidza kugadzirwa kwe chlorinated titanium dioxide muchikamu chinokurudzirwa, ukuwo kachideredza kusagadzirwa kwesulfuric acid titanium dioxide, iyo yave mukana wekushandura nekusimudzira mabhizinesi etitanium dioxide, kubvira ipapo mabhizinesi emuno etitanium dioxide akatanga kuwedzera kutsvaga nekusimudzira nekudyara mari muhunyanzvi hwekugadzira chlorinated titanium dioxide.
Mushure memakore akawanda ekutsvaga tekinoroji, kugadzirisa matambudziko akati wandei mu chloride titanium dioxide, Longbai Group yakagadzira mhando dzakasiyana dzezvigadzirwa zve chloride titanium dioxide zvemhando yepamusoro, mashandiro ese asvika padanho repamusoro repasi rose, mamwe mashandiro asvika padanho repamusoro repasi rose. Isu tiri yekutanga kubudirira kwekushandisa kwehunyanzvi hwemakambani makuru ekubikira chlorination titanium dioxide tekinoroji, tsika iyi yakasimbisawo kuti tekinoroji ye chlorination titanium dioxide yakasvibirira uye ine hushamwari kune nharaunda, nzira yayo yekuderedza marara eslag kupfuura sulfuric acid inoderedza kupfuura 90%, kuchengetedza simba rakazara kusvika 30%, kuchengetedza mvura kusvika 50%, mabhenefiti ezvakatipoteredza akakosha zvikuru, uye mashandiro ezvigadzirwa anosangana nezvinodiwa zvekupinza, Munguva imwe chete, monopoly yekunze mumusika wepamusoro yakaputsika, uye zvigadzirwa zvave kuzivikanwa nemusika.
Nekugadzirwa kwezvirongwa zvitsva zve titanium dioxide inogadzirwa nechlorine, kugona kwayo kugadzira kwasvika matani angangoita mamiriyoni 1.08 panosvika gore ra2022, zvichireva kuti kugona kwayo kugadzira kwese kwakawedzera kubva pa3.6% makore mashanu apfuura kusvika paanopfuura 22%, zvichideredza zvakanyanya kutsamira kwekunze kwe titanium dioxide inogadzirwa nechlorine, uye mukana wekuwana zvinhu pamusika watanga kuoneka.
Vari mukati meindasitiri vanotenda kuti zvichibva pakufambira mberi kwekushandiswa kwe titanium dioxide yepamusoro, pamwe nehurongwa hwazvino uye mamiriro aripo muindasitiri yemuno, shanduko yepamusoro ye titanium dioxide muChina yatanga kukanganisa mutambo. Zvinokurudzirwa kuti madhipatimendi ehurumende nemaindasitiri akakodzera awedzere kutarisisa nekutungamira kuronga mapurojekiti e chlorination, uye mabhizinesi anofanirawo kunangwa, kusiya mari yekudyara uye kuronga mapurojekiti ekugadzirisa zvinhu zvakadzoka shure uye zvigadzirwa zvakadzoka shure, uye kutarisa pakugadzira nekushandisa zvigadzirwa zvepamusoro kudzivirira njodzi yezvigadzirwa zvakaderera zvakanyanya.
