Titanium dioxide (TiO2) ichena pigment inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira pendi, machira, mapurasitiki uye zvizorwa. Inowanikwa mune akasiyana makristasi zvimiro, maviri akajairika mafomu ari anatase uye rutile. Kunzwisisa mutsauko uripo pakati peaya mafomu maviri eTiO2 kwakakosha pakusarudza iyo pigment chaiyo yekushandisa chaiyo.
Anatase uye rutile mapolymorphs eTiO2, zvichireva kuti iwo ane makemikari akafanana asi akasiyana makristasi zvimiro, zvichikonzera akasiyana zvivakwa uye maitiro ekuita. Imwe yemisiyano mikuru pakatianatase TiO2uye rutile TiO2 ndiyo chimiro chavo chekristaro. Anatase ine tetragonal chimiro, nepo rutile ine denser tetragonal chimiro. Iyi misiyano yezvimiro inotungamira kune shanduko mune yavo yemuviri nemakemikari zvinhu.
Panyaya ye optical properties, rutile TiO2 ine yakakwirira refractive index uye yakakura opacity kupfuura anatase TiO2. Izvi zvinoita kuti rutile TiO2 ive yekutanga sarudzo yezvishandiso zvinoda yakakwira opacity uye kuchena, senge pendi uye machira. Anatase titanium dioxide, kune rumwe rutivi, inozivikanwa nebasa rayo rakanaka rephotocatalytic, ichiita kuti ive yakakodzera kune zvakatipoteredza uye kuzvichenesa machira pamwe chete neUV yekudzivirira maapplication.
Chimwe chinhu chakakosha chekufunga kana uchienzanisa anatase uye rutile TiO2 ndiyo particle size uye nzvimbo yepamusoro. Anatase TiO2 kazhinji ine nzvimbo yakakura yepamusoro uye diki diki saizi, iyo inobatsira kune yayo yepamusoro reactivity uye photocatalytic performance.Rutile TiO2, kune rumwe rutivi, ine yakawedzera yunifomu saizi yekugovera uye yakadzika nzvimbo yepasi, ichiita kuti ive yakakodzera kune maapplication uko particle size consistency yakakosha, senge mapurasitiki uye cosmetics.
Zvakakoshawo kuziva kuti maitiro ekugadzira anatase uye rutile TiO2 anogona kukonzera shanduko mukuchena kwemakemikari uye kurapwa kwepamusoro. Izvi zvinhu zvinokanganisa dispersibility yavo, kuenderana nezvimwe zvinongedzo, uye kuita kwese kwese mukuumbwa kwakasiyana.
Muchidimbu, nepo zvese zviri zvivirianatase uye rutile TiO2akakosha pigment machena ane akasiyana ezvivakwa, kunzwisisa misiyano yavo yakakosha pakusarudza iyo chaiyo mhando yeimwe application. Kunyangwe kuri kudiwa kwekupenya kwakanyanya uye kuchena kwependi uye mapendi kana kudiwa kwepamusoro photocatalytic chiitiko mune zvakatipoteredza zvine hushamwari majasi, sarudzo pakati peanatase uye rutile TiO2 inogona kukanganisa zvakanyanya mashandiro uye kushanda kwechigadzirwa chekupedzisira. Nekufunga nezve crystal chimiro, optical properties, particle size uye nzvimbo yepamusoro yefomu imwe neimwe, vagadziri uye vanogadzira vanogona kuita zvisarudzo zvine ruzivo kuti vawane migumisiro inodiwa mukugadzirisa kwavo.
