What is titanium dioxide? How to distinguish the authenticity of titanium dioxide?

Ni iki Titimaum dioxyde?

Ikintu nyamukuru cya Titanium dioxyde ni tio2, nikihe cyimiti yingenzi ya minicalic muburyo bwimbaraga zera cyangwa ifu. Ntabwo ari uburozi, ifite umweru mwinshi nu mucyo, kandi afatwa nkiyi pigment yera yo kuzamura ibintu. Bikoreshwa cyane munganda nko kurema, plastiki, reberi, impapuro, wino, ceramics, ibirahure, nibindi.

Ⅰ.Titanium Dioxde Inganda Urunigi Igishushanyo:

(1) Hejuru ya titanium dioxide ya dioxide igizwe nibikoresho fatizo, harimo IINMENITE, Titanium yibanda, ritile, nibindi;

(2) Hagati yerekana ibikomoka kuri titanium dioxide.

.Titanium dioxyde ikoreshwa cyane mubice bitandukanye nkibice, plastike, padoka, wino, reberi, nibindi.

Ⅱ.imiterere ya kirisiti ya titanium dioxyde de titanide:

Titanium dioxyde ni ubwoko bwa polyhorphous combund, ifite imiterere itatu ya kirisiti isanzwe muri kamere, aribyo naatase, ritile na Brookite.
Hagabanutse na Anatase na sisitemu ya kotragonal, ihamye ubushyuhe busanzwe; Brookite ni iy'amabuye y'agaciro ya orthorhombic, hamwe n'imiterere idahwitse, bityo ifite agaciro gake mu nganda kuri ubu.

Mu nyubako eshatu, icyiciro cya Rutile nicyo gihamye. Icyiciro cya Anatase ntirushobora kuva mu cyiciro cya rutile hejuru ya 900 ° C, mugihe icyiciro cya Brookite kizahinduka mu cyiciro cya Rutile hejuru ya 650 ° C.

(1) RUTILE PESE Titoum Dioxyde

Muri rutuji ya rutile titanium dioxyde, atome iherereye hagati ya kristu ya kaburimbo, na atome esheshatu za ogisijeni ziherereye ku mfuruka ya Titanium-ogisijenict octahedron-ogisijeni. Buri ncya yahujwe kugeza 10 zikikije octahedrons (harimo na vertike umunani isangira impande ebyiri zisangiye), hamwe na tio2 molekile ebyiri zikora selile.

Igishushanyo cya Schematic cya Karukiro ya Crystal ya Rutile Icyiciro Titanium Dioxyde (ibumoso)
Uburyo bwo guhuza Titanium oxide octahedron (iburyo)

(2) Ikiciro cya Anatase Titanium dioxyde

Muri anatase icyiciro titanium dioxyde, buri titanium-ogisijeni octahedron ihujwe na 35 zikikije octahedrons), na molekile 4 zisangiye na selile.

T.Uburyo Uburyo bwa Titanium Dioxyde:

Igikorwa cyo gukora cya titanium dioxyde ahanini kirimo acide sulfuric hamwe nuburyo bwa chlorination.

(1) inzira ya acide sulfuric

Inzira ya sulfuric yo muri satanium dioxide ya dioxyde irimo acidolysis ifu ya titanium hamwe na aside sutanium yo kubyara titanium sutanium sutanium sutanium, icyo gihe hanyuma hydrolyzed kugirango itange aside metatitanic. Nyuma yo kubara no guhonyora ibicuruzwa bya dioxyde ya titanium. Ubu buryo burashobora kubyara notile titanium dioxyde.

(2) inzira ya chlorimination

Inzira ya chlorium ya dioxide ya dioxyde ikubiyemo kuva ifu ya rutile cyangwa hejuru-titanium ya titanium hamwe na coke hanyuma ikora amashusho yubushyuhe bwinshi bwo kubyara titanium tetrachloride. Nyuma yibicuruzwa byinshi byihuta, ibicuruzwa bya dioxide bya dioxyde byabonetse binyuze muburiro, gukaraba amazi, gukama, no guhonyora. Inzira ya chlorimination ya titanium dioxide irashobora kubyara ibicuruzwa biteye ubwoba.

Nigute ushobora gutandukanya ukuri kwa titanium dioxyde de titanie?

I. Uburyo bwumubiri:

(1)Uburyo bworoshye ni ukugereranya imiterere igiraho. Mpimbano titanium dioxyde ya dioxyde yumva yoroshye, mugihe Titanium ya dioxyde yumva rougher.

(2)Mugusenya n'amazi, niba ushyize dioxyde ya titanium hejuru yawe, impimbano iroroshye gukaraba, mugihe umuntu nyayo itari byoroshye koza.

(3)Fata igikombe cyamazi meza hanyuma umanure titanium dioxyde de titanide. Imwe ireremba hejuru nukuri, mugihe ikemura hasi ni impimbano (ubu buryo ntibushobora gukora kubicuruzwa byahinduwe cyangwa byahinduwe).

(4)Reba ibikuza mumazi. Mubisanzwe, titanium dioxyde yawe irashonje mumazi (usibye titanium dioxyde de plastiki, inka, hamwe na titanitic titanium dioxyde ya dioxyde, idahujwe mumazi).

II. Uburyo bwa Shimique:

(3) Niba icyitegererezo ari hydrophobic, ongeraho aside hydrochloric ntabwo izatera reaction. Ariko, nyuma yo kugota na Ethanol hanyuma wongere Acide ya Hydrochloric, niba ibituba byakozwe, byerekana ko icyitegererezo kirimo ifu ya calcium ya calcium carboum.
