Dioxyde de titanium ni iki?
Ikintu nyamukuru kigizwe na dioxyde ya titanium ni TIO2, ningirakamaro ya pigment ya organic organique muburyo bwa cyera cyangwa ifu yera. Ntabwo ari uburozi, ifite umweru mwinshi nubucyo, kandi ifatwa nkibara ryiza ryera ryogutezimbere umweru. Ikoreshwa cyane mu nganda nka coatings, plastike, reberi, impapuro, wino, ububumbyi, ibirahure, nibindi.

Ⅰ.Igishushanyo cy'inganda za Titanium dioxyde:
(1) Hejuru yumurongo wa titanium dioxyde yinganda igizwe nibikoresho fatizo, harimo ilmenite, titanium yibanze, rutile, nibindi;
(2Mid Hagati yerekana ibicuruzwa bya dioxyde de titanium.
.Dioxyde ya Titanium ikoreshwa cyane mubice bitandukanye nko gutwikira, plastiki, gukora impapuro, wino, reberi, nibindi.

Imiterere ya kristu ya dioxyde de titanium :
Dioxyde ya Titanium ni ubwoko bwa polymorphous compound, ifite uburyo butatu busanzwe bwa kirisiti muri kamere, aribwo anatase, rutile na brookite.
Byombi rutile na anatase ni sisitemu ya tetragonal sisitemu, ihagaze neza mubushyuhe busanzwe; brookite ni sisitemu ya orthorhombic sisitemu, ifite imiterere ya kristu idahindagurika, kubwibyo ifite agaciro gake mubikorwa byinganda.

Muburyo butatu, rutile icyiciro nicyo gihamye cyane. Icyiciro cya Anatase kizahinduka kuburyo budasubirwaho icyiciro cya rutile kiri hejuru ya 900 ° C, mugihe icyiciro cya brookite kizahinduka kuburyo budasubirwaho icyiciro cya rutile kiri hejuru ya 650 ° C.
(1 phase Rutile icyiciro cya titanium dioxyde
Mu cyiciro cya rutile dioxyde, Ti atom iherereye hagati ya kasitori ya kirisiti, naho atome esheshatu za ogisijeni ziri mu mfuruka ya octahedron ya titanium-ogisijeni. Buri octahedron ihujwe na octahedron 10 ikikije (harimo umunani wo kugabana vertike hamwe nimpande ebyiri zo kugabana), naho molekile ebyiri za TiO2 zigize selile imwe.

Uburyo bwo guhuza titanium oxyde octahedron (iburyo)
(2 phase Anatase icyiciro cya titanium dioxyde
Mu cyiciro cya anatase dioxyde de titanium, buri titanium-ogisijeni octahedron ihujwe na 8 octahedron ikikije (4 yo kugabana impande 4 na vertike yo kugabana), naho molekile 4 za TiO2 zigize selile imwe.

Ⅲ.Uburyo bwo Gutegura Dioxyde ya Titanium:
Umusaruro wa dioxyde de titanium ikubiyemo ahanini aside ya sulfurike na chlorine.

(1 process Uburyo bwa acide sulfure
Acide sulfurike yumusaruro wa dioxyde de titanium ikubiyemo aside aside ikora ifu ya titanium fer hamwe na acide sulfurike yibanze kugirango ikore titanium sulfate, hanyuma hydrolyz ikabyara aside metatitanic. Nyuma yo kubara no kumenagura, haboneka ibicuruzwa bya dioxyde de titanium. Ubu buryo bushobora kubyara anatase na rutile titanium dioxyde.
(2 process Inzira ya Chlorination
Inzira ya chlorine yumusemburo wa dioxyde de titanium ikubiyemo kuvanga ifu ya rutile cyangwa titanium nyinshi ya slag hamwe na kokiya hanyuma ugakora chlorine yubushyuhe bwo hejuru kugirango itange titanium tetrachloride. Nyuma yubushyuhe bwo hejuru cyane, ibicuruzwa bya dioxyde de titanium biboneka binyuze mu kuyungurura, gukaraba amazi, kumisha, no kumenagura. Inzira ya chlorine yumusaruro wa dioxyde de titanium irashobora kubyara gusa ibicuruzwa.
Nigute dushobora gutandukanya ukuri kwa dioxyde ya titanium?
I. Uburyo bw'umubiri:
(1)Uburyo bworoshye cyane nukugereranya imiterere mukoraho. Dioxyde de titanium yibeshya yumva yoroshye, mugihe dioxyde ya titanium yukuri ikomera.

(2)Iyo wogeje amazi, niba ushyize dioxyde de titanium mukiganza cyawe, iyimpimbano iroroshye koza, mugihe iyukuri itoroshye kwoza.
![微 信 图片 _202405301437542](http://www.sunbangtio2.com/uploads/微信图片_202405301437542.png)
(3)Fata igikombe cy'amazi meza hanyuma ushiremo dioxyde ya titanium. Iyareremba hejuru nukuri, mugihe iyituye hepfo ari impimbano (ubu buryo ntibushobora gukora kubicuruzwa byakorewe cyangwa byahinduwe).

(4)Reba imbaraga zayo mumazi. Mubisanzwe, dioxyde ya titanium irashobora gushonga mumazi (usibye dioxyde ya titanium yagenewe cyane cyane plastiki, wino, hamwe na dioxyde de titanium ya syntique, idashonga mumazi).

III. Hariho ubundi buryo bubiri bwiza:
.
. Gupima itara ryayo. Hasi yohereza urumuri ni, nukuri ifu ya titanium dioxyde ni.
