Chii chinonzi titanium dioxide?
Chikamu chikuru cheTitanium Dioxide is Tio2, iyo yakakosha inorganic kemikari pigment mune fomu yeiyo chena yakasimba kana hupfu. Izvo hazvisi zvepfumi, zvine machena kuchena uye kupenya, uye kunoonekwa seyakanakisa chena pigment yekuvandudza chero rukudzo rwekutumira. Inoshandiswa zvakanyanya mumaindasitiri akadai sejasi, mapurasitiki, rabha, pepa, ink, ceramics, girazi, nezvimwe.
Ⅰ.Titanium dioxide indasitiri yeteni Dhigiramu:
(1.
(2) Iyo icream inoreva kune titanium diexide zvigadzirwa.
.Titanium Dioxide inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana sejasi, mapurasitiki, mapepa, ink, rubber, etc.
Ⅱ.Ruva rekristaro reTitanium dioxide:
Titanium Dioxide rudzi rwePolymorphous inoenderana, iyo ine matatu makristaro maficha mune zvakasikwa, anonzi anatase, huwandu nebhinzi.
Ose maviri uye anatime ndewe tetragonal Crystal system, iyo yakagadzikana pasi pekudziya kwakajairika; Brookite ndezve orthorhombi crystal system, ine isina kugadzikana crystal chimiro, saka ine kukosha kushoma mune indasitiri parizvino.
Pakati pezvivakwa zvitatu, chikamu chine rukova ndirwo rwakagadzikana kwazvo. Anatasse chikamu chinoshanduka-shanduka chichinja kuita rutera
(1) rutile phae titanium dioxide
MuRutile Phase Titaniide Dioxide, TATOMS iri pakati pekristani Latices, uye maatomu matanhatu emakona ari pamakona eTitanium-oksijeni octahedron. Imwe neimwe octahedron yakabatana ne10 yakakomberedzwa octahedrons (inosanganisira sere kugovana vertices uye maviri kugovana mhezi), uye maviri mamalekyu2 mamorekuru anoumba chiteshi cheyuniti.

Iyo nzira yekubatanidza yeTitanium octahedron (kurudyi)
(2) AnatasE Phase Titanium Dioxide
MuAnatase Phase Titaniide dioxide, yega yega Titanium-oxygen octahedron yakabatana ne8 Octahedrons (4 kugovera madekwana uye 4 kugovana vertices), uye 4 tio2 mamorekuru anoumba cell.

Ⅲ.prepairation nzira dzeTitanium Dioxide:
Iyo yekugadzira maitiro eTitanium dioxide inonyanya kusanganisira sulfutic acid maitiro uye chirongwa cheClor.
(1) Sulfutic acid maitiro
Iyo Sulfuric Acid process yeTitanien Dioxide Proction inosanganisira iyo acidolysis yekuita yeTitanium Simbi Poda yekugadzira titanium Sulfate, iyo inobva yaita hydrolyzed yekugadzira metatitanic acid. Mushure mekunyaradzana uye kupwanya, titanium dioxide zvigadzirwa zvinowanikwa. Iyi nzira inogona kuburitsa anatase uye rutile titanium dioxide.
(2) chlorination maitiro
Maitiro eCHLLINGINGER yeTitanium Dioxide kugadzirwa kunosanganisira kusanganisa rutle kana yakakwira-titanium slag poda necke uye ndokuzotakura tembiricha yekugadzira titanium tetrachloride. Mushure mekushambadzira kwakakwirira, iyo Titanium dioxide chigadzirwa inowanikwa kuburikidza neyekufa, kushambidza mvura, kuoma, uye kupwanya. Iyo korlination process yeTitanium dioxide kugadzirwa kunogona kungogadzira zvigadzirwa zvine ruttile.
Maitiro ekusiyanisa chokwadi cheTitanium dioxide?
I. Nzira dzepanyama:
(1)Iyo nzira yakapusa ndeye kuenzanisa iwo maitiro nekubata. Fake titonium dioxide inonzwa kutsvedza, nepo chaiye titanium dioxide inonzwa rougher.
(2)Nekunhuhwirira nemvura, kana iwe ukaisa zvimwe titanium dioxide paruoko rwako, iyo inhema iri nyore kushambidza, nepo iye echokwadi asiri nyore kugeza.
(3)Tora kapu yemvura yakachena uye udonhedze titanium dioxide mukati maro. Iyo inoyerera kumusoro ndeyechokwadi ndeyechokwadi, nepo iyo inogadzirisa kusvika kuzasi ndeyenhema (Iyi nzira inogona kusashanda kune yakagadziriswa kana yakagadziridzwa zvigadzirwa).
(4)Tarisa iyo solubility mumvura. Kazhinji, titanium dioxide inonyudza mumvura (kunze kwekuti Titanium dioxide yakagadzirirwa mapurasitiki, ma-manhamba, uye mamwe maitiro ekugadzira titaniide, izvo zvinosemesa mumvura).
Ii. Nzira dzemakemikari:
.
(2.
(3) Kana iyo sampuli iri hydrophobic, inowedzera hydrochloric acid haizo kukonzera maitiro. Nekudaro, mushure mekunyorova neEthanol uye wozowedzera hydrochloric acid, kana mabhubhu anogadzirwa, zvinoratidza kuti sampu ine carcium carbonate poda.
III. Kune zvakare dzimwe nzira mbiri dzakanaka:
(1) Nekushandisa iyo imwechete fomu yePP + 30% gf + 5% PP-GF-G-ATTHIDE yezvinhu zvinokonzeresa, iyo inonyanya kuve yechokwadi yeTitanium dioxide (Rutile) ndeye.
(2) Sarudza iyo inojekesa resin, yakadai seyakajeka ab ne 0.5% titanium dioxide poda yakawedzera. Kuyera mwenje wayo. Iyo yakadzika iyo mwenje yekuputika ndeye, iyo yakawanda yechokwadi iyo Titanium dioxide poda iri.
