Iindaba-ithini iTitanium diokside? Ungawahlula njani ubunyani bukaTitanium diokside?

Ithini iTitanium diokside?

Eyona nto iphambili kwi-tioxiium dioxide yi-TIO2, eyona nto ibalulekileyo ye-pigganic yekhemikhali ngohlobo oluqinileyo okanye umgubo. Ayisiyo inetyhefu, inobumnyama obuphezulu kunye nokukhanya, kwaye kuthathwa njengeyona phawu lihle kakhulu lokuphucula ubumhlophe. Isetyenziswa ngokubanzi kumashishini anjengeengubo, iiplasitiki, irabha, iphepha, i-inki, i-inki, i-ceramics, iglasi, njl.

Ⅰ.I-Titanium Dioxide yeChain Diagogra:

(1) I-punstream ye-tithanium yeShishini leDinicoide iquka izinto ezingafunekiyo, kubandakanya i-Ilmerite, iTitanium igxila, i-ratule, njl.

(2) I-Middream ibhekisa kwiimveliso zeTitanium dioxide.

.I-titanium diokside isetyenziswa ngokubanzi kwimimandla eyahlukeneyo enjengeengubo, iiplasitiki, i-papermang, i-inki, irabha, njl.

I-Crystial ye-titanium diokide:

I-titanium dioxide luhlobo lwe-polymorphous computer, enezifo ezithathu eziqhelekileyo kwindalo, eyile eniatie, i-rute kunye ne-raokite.
Zombini i-rutile kunye ne-anatiase yenkqubo yekristali yeTetragonal, ezizinzileyo phantsi kobushushu obuqhelekileyo; I-Brookite yeyokukhristali ye-Ortarhombic, kunye nesakhiwo sekristali esingazinzanga, ngoko inamaxabiso amancinci kumzi mveliso okwangoku.

Phakathi kwezi zinto zintathu, isigaba se-rutile yeyona nto ilungileyo. Isigaba se-Anatiase siya kuguqula ngokungaguquki kwinqanaba le-routile ngaphezulu kwe-900 ° C, ngelixa iSigaba seBrookite iya kuguqula ngokungahambi kakuhle kwinqanaba le-rutle ngaphezulu kwe-650 ° C.

(1) Isigaba seRutile Dioxide

Kwisigaba se-rutile tioxide, i-athom ikwiziko le-crystal lattal, kwaye iiathom ezintandathu zeoksijini zibekwe kwiimbombo ze-titanium-oxygen. I-octahehedron nganye iqhagamshelwe kwi-10 yee-octahedrons ezijikeleze i-octahedrons (kubandakanywa ukwabelana ngesibhozo zokwabelana), kwaye iimolekyuli ezimbini ze-Tio2 zenza iseli.

(2) Isigaba seSigaba se-tinzaaum diokside

Kwisigaba se-ANATAEAUA ISISINIUM DiOXID, i-Titanium nganye-i-octgen octadron iqhagamshelwe kwii-Octahedrons ezi-8 ezijikeleze i-Octahedrons ezijikelezileyo (4 kwi-4 vertices), kwaye iimolekyuli ezi-4 zenza iseli.

Iindlela zokuSebenza zeTitanium Dioxide:

Inkqubo yemveliso yeTitanium dioxide ikakhulu ibandakanya inkqubo ye-acid ye-acid kunye nenkqubo ye-chlorition.

(1) Inkqubo ye-Acid ye-Acid

Inkqubo ye-acid ye-acid ye-Titanium dioxier ibandakanya ukuphendula i-acidolysis ye-tidolysic ye-tidolysic ene-acid ye-acid ye-tidoncric ye-tidorric ivelise i-titanium ye-titanium, eyenziwe nge-hydrolyzed ukuvelisa i-itatitanic acid. Emva kokuhlawulelwa kunye nokutyumza, iimveliso ze-titoxiium dioxide zifunyenwe. Le ndlela inokuvelisa i-Anases kunye ne-rutle titanium diokside.

(2) Inkqubo ye-chlorin

Inkqubo ye-chloriting ye-Titanium Dioxide ibandakanya ukudibanisa i-thutile okanye i-titanium ephezulu ye-titanium nge-coke kwaye ke iqhube i-coke kwaye iqhube i-chriting ephezulu ukuvelisa i-titanium tetrachloride. Emva kokuxinana kobushushu obuphezulu, imveliso ye-Titanium Dioxide ifunyenwe ngokufihlakeleyo, ukuhlamba amanzi, ukomisa, kwaye ityumze. Inkqubo ye-chlorin yemveliso yeTitanium dioxide inokuvelisa iimveliso zeRutnile kuphela.

Ungawahlula njani ubunyani bukaTitanium diokside?

I. Iindlela zomzimba:

(1)Eyona ndlela ilula yokuthelekisa isimo sengqondo ngokuchukumisa. I-titanium ye-fatanium dioxide ivakalelwa kukuba i-tioxide, ngelixa i-tetanium yokwenene ivakala ivakala.

(2)Ngokuthoba ngamanzi, ukuba ubeka i-tioxide ye-tioxide kwisandla sakho, inyani ilula ukuhlamba, ngelixa inyani ayilula ukuhlamba.

(3)Thatha ikomityi yamanzi acocekileyo kwaye ithole iTitanium dioxide kuyo. Lowo udadayo ukuya kumphezulu uyinyani, ngelixa lowo ulungisa ezantsi yinyani (le ndlela isenokungasebenzi kwiimveliso ezivulekileyo okanye eziguqulweyo).

(4)Jonga isothulo lwayo emanzini. Ngokubanzi, iTitanium Dioxide inyibilikiswa emanzini (ngaphandle kwe-tifoxite yenzelwe ngokukhethekileyo iplastiki, i-inks, kunye ne-tioxiting ye-tioxide, enganyibilikiyo emanzini).

II. Iindlela zekhemikhali:

(3) Ukuba isampulu yi-hydrophobic, ukongeza i-hydrochloric acid ayiyi kubangela impendulo. Nangona kunjalo, emva kokuyima i-ethanol kwaye yongeza i-hydrochloric acid, ukuba i-qabbs iveliswa, iqinisekisa ukuba isampulu ine-calcium ye-calcium carbonate powder.
