Nhanganyaya:
Titanium dioxide (TiO2) ndechimwe chezvinhu zvakasiyana-siyana uye chinoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira pendi nemapendi, zvekuzora, uye kunyangwe chikafu.Kune matatu makuru makristasi zvimiro mumhuri yeTiO2:rutile anatase uye brookite.Kunzwisisa mutsauko uripo pakati pezvivakwa izvi kwakakosha pakubatanidza zvimiro zvavo zvakasiyana uye kuvhura kugona kwavo.Mune ino blog, isu tichanyatso tarisisa zvivakwa uye mashandisirwo erutile, anatase, uye brookite, tichiburitsa aya matatu anonakidza marudzi etitanium dioxide.
1. Rutile Tio2:
Rutile ndiyo yakanyanya kuwanda uye yakagadzikana chimiro chetitanium dioxide.Iyo inoratidzirwa neiyo tetragonal crystal chimiro, inosanganisira yakanyatsozara octahedron.Uku kurongeka kwekristaro kunopa rutile yakanakisa kuramba kune UV mwaranzi, ichiiita sarudzo yakanaka yekugadzira sunscreen uye UV-inovharira machira.Rutile Tio2's high refractive index zvakare inokwidziridza kupenya kwayo uye kupenya, zvichiita kuti ive yakakodzera kugadzira pendi dzemhando yepamusoro nemaingi ekudhinda.Pamusoro pezvo, nekuda kwekudzikama kwayo kwemakemikari, Rutile Tio2 ine maapplication mune catalyst rutsigiro masisitimu, ceramics, uye optical zvishandiso.
2. Anatase Tio2:
Anatase imwe yakajairika crystalline fomu yetitanium dioxide uye ine nyore tetragonal chimiro.Kuenzaniswa ne rutile,Anatase Tio2ine yakaderera density uye yakakwirira pamusoro nzvimbo, ichipa yakakwirira photocatalytic basa.Naizvozvo, inoshandiswa zvakanyanya mukushandisa photocatalytic senge mvura nemhepo kucheneswa, kuzvichenesa pachezvako, uye kurapwa kwemvura yetsvina.Anatase inoshandiswawo sechinhu chinochenesa mukugadzira mapepa uye serutsigiro rwerutsigiro mukusiyana kwemakemikari kuita.Uyezve, maitiro ayo emagetsi akasiyana anoita kuti ive yakakodzera kugadzirwa kwedhayi-sensitized solar cell uye sensors.
3. Brookite Tio2:
Brookite ndiyo isinganyanyo zivikanwa yetitanium dioxide uye ine orthorhombic crystal chimiro chakasiyana zvakanyanya kubva kune tetragonal zvimiro zve rutile uye anatase.Brookite inowanzoitika pamwe chete nemamwe mafomu maviri uye ine mamwe maitiro akasanganiswa.Chiitiko chayo chinokonzeresa chakakwira kupfuura rutile asi chakaderera pane anatase, zvichiita kuti ive yakakosha mune mamwe solar cell application.Pamusoro pezvo, iyo yakasarudzika kristaro chimiro chebrookite inobvumira kuti ishandiswe seye mineral specimen muzvishongo nekuda kwekuonekwa kwayo kushoma uye kwakasiyana.
Mhedziso:
Kupfupisa, izvo zvitatu zverutile, anatase uye brookite zvine akasiyana makristasi zvimiro uye zvivakwa, uye chimwe nechimwe chine zvacho zvakanakira uye mashandisiro.Kubva pakudzivirira kweUV kuenda kufotocatalysis uye nezvimwe, idzi mafomu etitanium dioxidekuita basa rakakosha mumaindasitiri akasiyana, kusunda miganhu yehunyanzvi uye kugadzirisa hupenyu hwedu hwezuva nezuva.
Nekunzwisisa zvivakwa uye mashandisirwo erutile, anatase uye brookite, vaongorori nemakambani vanogona kuita sarudzo dzine ruzivo pakusarudza chimiro chetitanium dioxide chinonyatsoenderana nezvavanoda chaizvo, kuve nechokwadi chekushanda kwakakwana uye zvinotarisirwa mhedzisiro.
