Anatase titanium dioxide, tshuaj lom neeg cov npe titanium dioxide, cov tshuaj molecular Ti02, molecular phaus 79.88. Cov hmoov dawb dawb, txheeb ze ceev 3.84. Lub ntsiab lus melting yog 1560 ° C. Dej haum O.02%. Kev kub nyhiab ntau heev (GG gt; 700 heating) cua sov kom hloov mus ua kua rutile. Lub ntsiab lus melting yog li 1800 ° C. Qhov ntsuas refractive yog 2.55. Qhov nruab nrab ntawm qhov nruab nrab loj yog 0.15 ～ 0.23um. Mohs hardness ntawm 5 ～ 6. Cov tshuaj muaj zog ruaj khov, lub teeb tsis kam, tiv tshav kub, tiv taus acid acid thiab dilute alkali tsis kam. Nws muaj lub zog tinting zog (zais zog) thiab dispersion zog. Lub sijhawm ua haujlwm tsis tshua zoo raws li cov rutile titanium dioxide, lub teeb tiv thaiv tsis zoo, thiab cov kua nplaum txheej yog yooj yim rau hmoov tom qab sib xyaw nrog cov cob. Qhov kub ntawd siab tshaj 400 ° C thiab nws yog daj daj. Nws yog insoluble hauv dej, organic acids thiab inorganic acids, tab sis soluble hauv concentrated sulfuric acid, alkali thiab hydrofluoric acid. Tsis muaj tshuaj lom, nrog ntau dua cov tshuaj tau tso cai ntawm 10mg / m3 hauv huab cua.

Tshuaj muaj zog:

Anatase titanium dioxide yog qhov ruaj khov nyob rau hauv cov tshuaj lom neeg thiab yog ib hom tshuaj acidic amphoteric oxide. Nws kog tshua nrog lwm cov ntsiab lus thiab cov khoom sib xyaw hauv chav sov thiab tsis muaj kev cuam tshuam rau cov pa oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, thiab sulfur dioxide. Nws yog insoluble hauv dej, rog, dilute acid, inorganic acid thiab alkali, tab sis tsuas yog soluble hauv hydrogen. Cov kua nyeem ua kua. Tab sis nyob rau hauv qhov kev txiav txim ntawm lub teeb, titanium dioxide tuaj yeem yauv pauv tas li oxidation-txo cov tshuaj tiv thaiv thiab muaj kev ua haujlwm photochemical. Anatase titanium dioxide tshwj xeeb pom tseeb hauv qab ultraviolet teeb. Cov cuab yeej no ua rau cov pa roj carbon dioxide ua ib qho chaw ua kom muaj zog ntau oxidation catalyst rau qee cov sib txuas hauv cov cev muaj zog thiab ib qho txo kev txaus ntshai rau qee cov organic sib txuas.

Thov

Titanium dioxide rau papermaking feem ntau siv anatase titanium dioxide tsis kho saum npoo, uas tuaj yeem ua lub luag haujlwm ntawm fluorescence thiab ntxuav hniav dawb, thiab nce cov ntawv dawb. Cov titanium dioxide siv nyob rau hauv kev lag luam number case muaj hom rutile thiab hom anatase, uas yog qhov xim ci uas tsis tuaj yeem hauv cov xim number case. Cov titanium dioxide siv hauv kev lag luam textile thiab tshuaj fiber ntau yog siv los ua tus neeg sawv cev matting. Txij li cov hom anatase yog hom softer dua li cov xim liab kub, hom anatase feem ntau siv. Titanium dioxide tsis yog tsuas yog siv los ua cov xim ua yeeb yaj kiab hauv kev lag luam roj hmab, tab sis kuj tseem muaj cov khoom ua kom muaj zog, tiv thaiv kev laus, thiab ua kom lub zog, thiab feem ntau ua raws li anatase.
