Titanium Dioxide yog dab tsi? Nws siv rau dab tsi?

Titanium dioxide yog ib qho inorganic compound nrog cov tshuaj formula TiO2. Nws yog cov khoom dawb lossis hmoov amphoteric oxide nrog qhov hnyav ntawm molecular ntawm 79.866. Nws yog non-toxic, muaj qhov zoo tshaj plaws opacity, qhov zoo tshaj plaws whiteness thiab brightness, thiab raug suav hais tias yog cov xim dawb zoo tshaj plaws hauv ntiaj teb niaj hnub no. Tsab ntawv xov xwm no yuav tshawb xyuas qhov tshuaj lom neeg, kev siv dav thiab lub luag haujlwm tseem ceeb ntawm titanium dioxide hauv lub neej niaj hnub no.

I. Yam ntxwv ntawm titanium dioxide

1.Lub cev muaj zog: Titanium dioxide yog cov hmoov dawb dawb nrog lub ntiajteb txawj nqus ntawm 4.23, lub melting point ntawm 1830 degree, ib qho loj tshwj xeeb nto, thiab muaju nyob rau hauv ntau hom.

2.Chemical zog: Titanium dioxide yog ib qho chaw ruaj khov uas tsis hnov ​​​​mob nrog oxygen, dej, alkali thiab ntau cov organic hauv chav sov, tab sis muaj cov khoom siv tshuaj xws li catalytic oxidation thiab photocatalytic decomposition nyob rau hauv kub thiab ultraviolet rays.

3.Optical zog: Cov khoom siv kho qhov muag ntawm titanium dioxide yog qhov zoo heev, nrog cov pob tshab siab, siab refractive index, siab reflectivity, siab optical absorption thiab lwm yam ntxwv. Nws yog ib qho tseem ceeb ntawm cov khoom siv kho qhov muag.

II.Main siv titanium dioxide
1>Xim thiab xim: Raws li cov xim dawb loj, titanium dioxide yog siv dav hauv kev lag luam xim, muab kev zais zoo heev thiab xim ruaj khov.
2>Cov khoom xyaw tshuaj pleev ib ce: Vim nws cov khoom tsis muaj tshuaj lom thiab tiv thaiv UV, titanium dioxide yog dav siv los ua tshuaj pleev thaiv hnub lub cev hauv cov tshuaj pleev ib ce.
3>Cov ntaub ntawv Photocatalyst: Titanium dioxide tuaj yeem ua kom cov pa phem hauv cov pa phem hauv lub teeb thiab siv rau kev lim dej thiab kev kho dej.
4>Hnub ci hlwb: Raws li cov khoom siv hluav taws xob hloov hluav taws xob, titanium dioxide tuaj yeem txhim kho lub zog hloov pauv hauv lub hnub ci thiab roj hlwb.
5>Kev kho mob: Titanium dioxide nanoparticles qhia tau hais tias muaj peev xwm zoo hauv kev xa tshuaj thiab bioimaging.
6>Khoom noj khoom haus additives: Titanium dioxide, raws li cov khoom noj additives, muaj lub luag hauj lwm ntawm cov zaub mov xim, txhim kho zaub mov stability, npog cov zaub mov tsis zoo, txhim kho cov khoom noj khoom haus, thiab txhawb kev qab los noj mov.

III.Kev npaj ntawm titanium dioxide
1>Txoj kev sulfuric acid: Titanium sulfate yog tsim los ntawm cov tshuaj tiv thaiv ntawm sulfuric acid thiab titanium ore, thiab ces calcined kom tau titanium dioxide.
2>Txoj kev chlorination: Siv cov tshuaj chlorine los teb cov titanium ore los tsim titanium tetrachloride, uas tom qab ntawd oxidized kom tau titanium dioxide.
3>Gas theem txoj kev: ncaj qha synthesize nano-loj titanium dioxide los ntawm cov roj theem tshuaj tiv thaiv.

IV.Kev nyab xeeb teeb meem ntawm kev siv titanium dioxide
Thaum siv titanium dioxide, koj yuav tsum tau xyuam xim rau cov teeb meem hauv qab no:
1.Titanium dioxide yog cov khoom tsis muaj tshuaj lom thiab tsis muaj teeb meem, tab sis kev nqus plua plav mus ntev yuav ua rau muaj kev cuam tshuam tsis zoo rau lub ntsws.
2.Titanium dioxide hmoov yog flammable, thiab kev tiv thaiv hluav taws yuav tsum tau ua thaum siv.
3.Nyob rau hauv cov tshuaj tiv thaiv catalytic ntawm titanium dioxide, qee yam tshuaj lom thiab teeb meem yuav raug tsim, thiab kev tiv thaiv yuav tsum tau ua.

Titanium dioxide plays lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub nrog nws cov tshuaj zoo heev thiab lub cev. Los ntawm cov txheej txheem rau tshuaj, los ntawm kev tiv thaiv ib puag ncig mus rau lub zog, titanium dioxide muaj ntau yam kev siv thiab kev cuam tshuam deb. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, peb tuaj yeem pom tau tias kev siv titanium dioxide hauv lub neej yav tom ntej yuav muaj ntau haiv neeg thiab ua rau muaj txiaj ntsig zoo rau tib neeg txoj kev loj hlob.
