Titanium dioxide(TiO2) ivara rinoshandiswa zvakasiyana-siyana rinoshandiswa mumaindasitiri akasiyana siyana, kusanganisira pendi, machira, mapurasitiki uye zvekuzora. Inowanikwa mumhando mbiri dzekristaro: rutile uye anatase. Kunzwisisa mutsauko uripo pakati pemafomu maviri aya kwakakosha pakusarudza iyo chaiyo TiO2 mhando yeimwe application.
Rutile uye anatase ese ari maviri mafomu etitanium dioxide, asi ane zvimiro zvakasiyana zvinoita kuti ive yakakodzera kushandiswa kwakasiyana. Rutile inozivikanwa nekunaka kwayo kweUV kuramba uye kuramba kwemamiriro ekunze, zvichiita kuti ive sarudzo yakakurumbira kune zvekunze zvekushandisa senge pendi yekunze uye machira. Anatase, kune rumwe rutivi, inokosheswa nebasa rayo repamusoro rephotocatalytic, ichiita kuti ive yakanaka kune maapplication akadai sekuzvichenesa majasi uye masisitimu ekuchenesa mweya.
Imwe yemisiyano mikuru pakati perutile uye anatase ndeye crystal chimiro chavo. Rutile ine tetragonal crystal structure, nepo anatase ine yakanyanya kuoma orthorhombic crystal structure. Uyu mutsauko wezvimiro unotungamira kune shanduko mune yavo yemuviri nemakemikari zvimiro, pakupedzisira zvichikanganisa mashandiro avo mumashandisirwo akasiyana.
Panyaya ye optical properties,rutile TiO2ine yakakwira refractive index uye opacity pane anatase. Izvi zvinoita kuti rutile ive sarudzo yekutanga yezvishandiso uko opacity uye kupenya kwakakosha, senge pendi chena uye machira. Anatase, kune rumwe rutivi, ine yakaderera refractive index uye inowanzoshandiswa mumashandisirwo apo kujeka uye kujekesa kunodiwa, zvakadai semajasi akajeka uye sunscreens.
Chimwe chinhu chakakosha kufunga pakusarudza pakati perutile uye anatase TiO2 ibasa ravo refotocatalytic. Anatase ine yakakwirira photocatalytic kunyatsoshanda pane rutile, ichiita kuti ive yakakodzera kune zvikumbiro zvinoda kuzvichenura uye kuderedza kusvibisa. Ichi chivakwa chakonzera kushandiswa kweanatase titanium dioxide muzvigadzirwa zvakaita segirazi rekuzvichenesa, masisitimu ekuchenesa mweya uye antimicrobial coatings.
Izvo zvakakoshawo kuziva kuti maitiro ekugadzira e rutile TiO2 uyeanatase TiO2zvinogona kusiyana, zvichikonzera mutsauko muhukuru hwavo, nzvimbo yepamusoro, uye agglomeration maitiro. Izvi zvinhu zvinogona kukanganisa kupararira, kugadzikana uye kuita kweTiO2 mune akasiyana magadzirirwo, zvichiwedzera kusimbisa kukosha kwekusarudza mhando yakakodzera kune chaiyo application.
Muchidimbu, mutsauko uripo pakati perutile TiO2 uye anatase TiO2 unowedzera kupfuura zvimiro zvavo zvekristaro kune yavo yekuona, photocatalytic, uye kugadzirisa zvivakwa. Kunzwisisa misiyano iyi kwakakosha pakuita sarudzo dzine ruzivo paunenge uchisarudza TiO2 kune akasiyana maapplication. Nekusarudza iyo yakakodzera fomu yetitanium dioxide, vagadziri vanogona kukwidziridza mashandiro uye mashandiro ezvigadzirwa zvavo, pakupedzisira vachisangana nezvinodiwa zvevashandisi vekupedzisira.
