Titanium Dioxide

Titanium dioxide (TiO2) ose pa'epa'e pa'epa'e fa'aaoga lautele i alamanuia eseese ona o ona uiga fa'apitoa. O se faʻamatalaga lautele lea o le titanium dioxide, ona meatotino, ma ona faʻaoga eseese:

1. Fua'iga Vailaau: Titanium dioxide ose oxide fa'alenatura o le titanium fa'atasi ai ma le fua fa'a vaila'au TiO2. E i ai i le tele o foliga tioata, ma rutile ma anatase e sili ona taatele. Rutile TiO2 ua lauiloa ona o lona faasinomaga maualuga ma le opacity, ae o anatase TiO2 o loʻo faʻaalia le gaioiga sili atu o le photocatalytic.
2. Pigment Paʻepaʻe: O se tasi o faʻaoga muamua o le titanium dioxide o se paʻepaʻe paʻepaʻe i vali, paʻu, palasitika, ma pepa. E tuʻuina atu le susulu, opacity, ma le paʻepaʻe i nei mea, e faʻaalia ai le vaʻaia ma faʻaleleia atili ai le ufiufi ma le mana natia. E sili atu le titanium dioxide nai lo isi lanu pa'epa'e ona o le lelei tele o le fa'asalalauina o le malamalama ma le tete'e atu i lanu.
3. UV Absorber ma Sunscreen: Titanium dioxide o loʻo faʻaaogaina lautele e fai ma UV absorber i sunscreens ma mea teuteu. E galue e pei o se sunscreen faaletino e ala i le atagia ma le faʻasalalauina o le UV radiation, ma puipuia ai le paʻu mai aʻafiaga leaga e pei o le mu o le la, matua tuai, ma le kanesa o le paʻu. Nanoscale titanium dioxide particles e masani ona faʻaaogaina i le la mo le faʻamalamalamaina ma le lautele o alaleo UV puipuiga.
4. Photocatalyst: O nisi ituaiga o titanium dioxide, aemaise lava anatase TiO2, e faʻaalia le gaioiga photocatalytic pe a faʻaalia i le malamalama ultraviolet. O lenei meatotino e mafai ai e le titanium dioxide ona faʻatupuina faʻalavelave faʻalavelave eseese, e pei o le pala o mea eleelea ma le faʻamaʻaina o luga. Photocatalytic titanium dioxide e faʻaaogaina i le faʻamamaina o le tagata lava ia, faiga faʻamamaina o le ea, ma le faʻaogaina o vai.
5. Mea'ai Fa'aopoopo: Ua fa'amaonia le Titanium dioxide e fai ma mea'ai (E171) e fa'atulafono fa'atulafonoina e pei o le FDA ma le European Food Safety Authority (EFSA). E masani ona faʻaaogaina i meaʻai, e pei o mea faʻafefete, mea tao tao, ma meaʻai susu, e fai ma sui paʻepaʻe ma opacifier. O le titanium dioxide e fesoasoani e fa'aleleia atili foliga ma foliga o mea'ai, ma fa'amatagofieina ai i tagata fa'atau.
6. Lagolago Catalyst: Titanium dioxide e avea o se lagolago faʻamalosi i gaioiga faʻasolosolo eseese, e aofia ai catalysis eseese ma le faʻaleleia o le siosiomaga. E maua ai se vaega maualuga ma le fa'avae lagolago mautu mo nofoaga fa'ato'aga, fa'afaigofieina gaioiga fa'ama'i lelei ma le fa'aleagaina. O lo'o fa'aogaina fa'amalosi e lagolago ai le titanium dioxide i fa'aoga e pei o le fa'aogaina o ta'avale ta'avale, gaosiga o le hydrogen, ma le fa'aogaina o vai otaota.
7. Electroceramics: Titanium dioxide e faʻaaogaina i le gaosiga o mea eletise, e pei o capacitors, varistors, ma sensors, ona o lona dielectric ma semiconductor properties. E galue e pei o le maualuga-k dielectric meafaitino i capacitors, mafai ai le teuina o le malosi eletise, ma avea o se kesi-maaleale meamea i sensors mo le suʻeina o kasa ma faʻafefiloi faʻaola.

I le aotelega, o le titanium dioxide o se mea faʻapitoa ma le tele o faʻaoga, e aofia ai le paʻepaʻe paʻepaʻe, UV absorber, photocatalyst, meaʻai faaopoopo, lagolago faʻamalosi, ma vaega eletise. O lona tu'ufa'atasiga tulaga ese o meatotino e matua taua ai i pisinisi e pei o vali ma fa'aofuofu, mea teuteu, fa'aleleia o le si'osi'omaga, mea'ai, mea tau eletise, ma le soifua maloloina.
