Titanium Dioxide's Chengetedzo uye Supply Issues muna 2017

Titanium dioxide (TiO2) ndeimwe yemavara anonyanya kukosha muhupenyu hwedu hwezuva nezuva. Izvo zvakakosha muzvinhu zvemazuva ese senge mushonga wemazino, sunscreen, chewing gums uye pendi. Yanga iri munhau kweakawanda e2017, kutanga nemitengo yakakwira. Pakave nekubatanidzwa kwakakosha muchikamu cheChina cheTiO2, zvichitungamira kumitengo yakakwira, uye China inonzi yakarambidza kugadzirwa nekuda kwekunetsekana kwemhando yemhepo. Moto waNdira 2017 paHuntsman's TiO2 chirimwa muPori, Finland, yakawedzera kuganhurira kugona kweTiO2 yemifananidzo yemifananidzo.

Izvi zvakaita kuti vagadziri veinki vazivise kuwedzera kwemitengo painki vachishandisa titanium dioxide; semuenzaniso, Siegwerk yakapa chirevo mukutanga kwaKurume ichizivisa mitengo yakakwira yeingi dzese dzine titanium dioxide.

Zvese izvi zvinonetsa zvakaringana, asi nyaya dzezvakatipoteredza dzauya izvo zvinogona kutora TiO2 kune imwe, yakanyanya kuoma, nhanho. TiO2 chinhu chakakosha mumishonga yezuva, uye kwave nekunetsekana muEurope pamusoro pekushandiswa kwenanoparticles muzuva, mushonga wemazino nezvimwe zvakawanda. Iko kunetseka, kunyanya, kuri pamusoro pe nanoparticles yeTiO2. Izvi zvakaita kuti European Chemicals Agency (ECHA) ione kuti titanium dioxide inogona kuita carcinogen kana ikafemerwa.
Pakave nezvidzidzo zvishoma nezve chepfu yetitanium dioxide.

Munguva pfupi yapfuura, nzvimbo yeFrench chikafu uye Occupational Health and Safety Bureau (Anses) mubepa, maererano nezvayakawana, yakaratidza kuti kushandiswa kwetitanium dioxide sechinhu chinogona kukonzera kenza kuburikidza nekufema kwe1 B-type carcinogens, chikumbiro ichi chichava. yakagamuchirwa zviri pamutemo mukunyora kana mushure mechikamu chaGunyana.

Nhau dzakatekeshera muindasitiri iyi. Titanium dioxide mabhizinesi ane maonero. Titanium dioxide mumagumo haisi carcinogenic zvinhu, hutano hwevanhu pakupedzisira hapana chinogona kukuvadza?

"Titanium dioxide haina carcinogenic uye haina mhedzisiro pahutano hwevanhu," akadaro Shijiang, Mutevedzeri wemunyori-Gene.ral yeChina Coatings Industry Association. ”

Min, general maneja weindasitiri yetitanium, akati: “Titanium dioxide haisi zvinhu zvine chepfu, yakashanda muindasitiri yetitanium dioxide kwemakore anopfuura 10, haina kunzwa nemhaka yetitanium dioxide uye kenza.” Kana titanium dioxide iri carcinogenic, mhedzisiro inogona kuva yakakura. ”

Titanium dioxide yakachengeteka here?

Iko hakuna humbowo chaihwo hwekuti titanium dioxide ine carcinogenic. Chekutanga, chinhu chose chingori kurudziro nenharaunda yechikafu yeFrance uye Occupational Health and Safety Bureau, uye inoda kumwe kutsvagisa.

Chechipiri, nharaunda yeFrench chikafu uye Occupational Health and Safety Administration inongokurudzira kuiswa kwetitanium dioxide se 1-b carcinogen inogona kukonzera cancer nekufema. Ruzivo pamusoro pemagwaro akakodzera epanguva anoratidza kuti kwave kune hukama masangano muUnited States DuPont kambani titanium dioxide kugadzira chirimwa 2,477 vashandi kuita tsvakiridzo yekutevera, mhedzisiro inoratidza kuti kusangana kwakananga netitanium dioxide hakuzowedzere zvakanyanya vashandi vemapapu. kenza, zvirwere zvisingaperi zvekufema, pleural maronda nezvimwe zvirwere zvine chekuita nenjodzi.

Mukuwedzera, zvakasiyana-siyana zvakawanikwa zvakafanana zvakaratidza kuti titanium dioxide haikonzeri kuratidzwa kune huwandu hwekenza yemapapu chiitiko chekukwira. Data kubva kuInternational Agency for Cancer Research inoratidzawo kuti hapana humbowo hwakakwana hwekuongorora kana titanium dioxide inogona kukonzera gomarara muvanhu. Titanium dioxide inoshandiswa zvakanyanya pasina inotsiva.
