Titanium Dioxide

Titanium dioxide (TiO2) iwhite pigment inoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kwehunhu hwayo hwakasiyana. Heino mhedziso yetitanium dioxide, zvimiro zvayo, uye mashandisirwo ayo akasiyana:

1. Kemikari Inoumbwa: Titanium dioxide iokisidhi inowanzoitika yetitanium ine kemikari formula TiO2. Inowanikwa mune akati wandei makristasi mafomu, ane rutile uye anatase ari akajairika. Rutile TiO2 inozivikanwa neiyo yakakwira refractive index uye opacity, nepo anatase TiO2 inoratidza yepamusoro photocatalytic chiitiko.
2. White Pigment: Imwe yeanonyanya kushandiswa yetitanium dioxide yakaita sepigment chena mupendi, machira, mapurasitiki, uye bepa. Inopa kupenya, kupenya, uye kuchena kune izvi zvinhu, zvichiita kuti zvitaridzike uye kuwedzera kuvharika kwazvo uye simba rekuhwanda. Titanium dioxide inodiwa pane mamwe machena pigment nekuda kwekunakisisa kwayo-kuparadzira mwenje zvimiro uye kuramba kushanduka.
3. UV Absorber uye Sunscreen: Titanium dioxide inoshandiswa zvakanyanya seUV inonyudza mune sunscreens uye zvigadzirwa zvekuzora. Inoshanda seyakadzivirirwa zuva nekuratidzira uye kuparadzira mwaranzi yeUV, nekudaro ichidzivirira ganda kubva kune zvinokuvadza zvakaita sekupiswa nezuva, kuchembera nguva isati yakwana, uye gomarara reganda. Nanoscale titanium dioxide particles anowanzo shandiswa mukugadzirwa kwezuva kuitira kujeka uye kuchengetedzwa kwakafara kweUV.
4. Photocatalyst: Mamwe mafomu etitanium dioxide, kunyanya anatase TiO2, anoratidza chiitiko chephotocatalytic kana akaiswa kune ultraviolet mwenje. Ichi chivakwa chinogonesa titanium dioxide kukonzeresa maitiro akasiyana siyana emakemikari, sekuora kwezvinosvibisa organic uye kuomeswa kwepasi. Photocatalytic titanium dioxide inoshandiswa mukuzvichenesa machira, masisitimu ekuchenesa mweya, uye kushandiswa kwekuchenesa mvura.
5. Chikafu Chinowedzera: Titanium dioxide inotenderwa sechikafu chekuwedzera (E171) nemasangano anodzora akadai seFDA neEuropean Food Safety Authority (EFSA). Inowanzo shandiswa muzvigadzirwa zvekudya, senge confectionery, zvakabikwa, uye zvigadzirwa zvemukaka, semuchena mumiriri uye opacifier. Titanium dioxide inobatsira kuvandudza kutaridzika uye kuumbwa kwezvinhu zvekudya, zvichiita kuti zvive zvakanyanya kutaridzika kune vatengi.
6. Catalyst Support: Titanium dioxide inoshanda sechitsigiro chinokonzeresa mumhando dzakasiyana dzemakemikari, kusanganisira heterogeneous catalysis uye kugadzirisa kwezvakatipoteredza. Inopa nzvimbo yakakwirira yepamusoro uye yakagadzikana tsigiro chimiro che catalytic inoshanda masaiti, kufambisa inoshanda magadzirirwo emakemikari uye kushatisa kusvibiswa. Titanium dioxide-inotsigirwa catalysts inoshandiswa mukushandisa senge mota epoust kurapwa, kugadzirwa kwehydrogen, uye marara emvura.
7. Electroceramics: Titanium dioxide inoshandiswa mukugadzirwa kwezvinhu zvemagetsi, senge capacitors, varistors, uye masensa, nekuda kweiyo dielectric uye semiconductor zvimiro. Inoshanda seyakakwirira-k dielectric zvinhu muma capacitors, zvichiita kuti kuchengetwa kwesimba remagetsi, uye segasi-sensitive material muma sensors ekuona magasi uye volatile organic compounds.

Muchidimbu, titanium dioxide ndeye zvinhu zvakasiyana-siyana zvine huwandu hwemashandisirwo, zvinosanganisira senge chena pigment, UV absorber, photocatalyst, yekuwedzera chikafu, catalyst rutsigiro, uye electroceramic chikamu. Kusanganiswa kwayo kwakasarudzika kwezvivakwa kunoita kuti ive yakakosha mumaindasitiri akadai sependi uye machira, zvizorwa, kugadzirisa kwezvakatipoteredza, chikafu, zvemagetsi, uye hutano hwehutano.
