Titanium(IV) oxide CAS 13463-67-7 Nhanganyaya
quality
White amorphous powder. Kune matatu akasiyana etitanium dioxide aripo mune zvakasikwa: rutile is a tetragonal crystal; Anatase is a tetragonal crystal; Plate perovskite is orthorhombic crystal. Yero mukupisa zvishoma uye shava mukupisa kwakasimba. Insoluble mumvura, hydrochloric acid kana nitric acid kana dilute sulfuric acid uye organic solvents, soluble in concentrated sulfuric acid, hydrofluoric acid, inonyungudika zvishoma mualkali uye inopisa nitric acid. Inogona kubikwa kwenguva yakareba kuti inyunguduke mu concentrated sulfuric acid uye hydrofluoric acid. Inopindirana neyakanyungudutswa sodium hydroxide kuumba titanate. Pakupisa kwepamusoro, inogona kuderedzwa kusvika pasi-valent titanium nehydrogen, carbon, metal sodium, nezvimwewo, uye inopindirana necarbon disulfide kuumba titanium disulfide. Iyo refractive index yetitanium dioxide ndiyo yakakura mune chena pigments, uye rutile rudzi i8. 70, 2.55 yeanatase type. Sezvo zvese anatase nendiro titanium dioxide zvichishanduka kuita rutile pakupisa kwakanyanya, kunyungudika nekuvira kwendiro yetitanium neanatase inenge isipo. Chete rutile titanium dioxide ine nzvimbo yekunyunguduka uye nzvimbo yekuvira, nzvimbo yekunyunguduka ye rutile titanium dioxide i1850 °C, nzvimbo yekunyunguduka mumhepo i (1830 pasi 15) °C, uye nzvimbo yekunyunguduka mukuwedzerwa kweokisijeni i1879 °C. , uye nzvimbo yakanyunguduka inoenderana nekuchena kwetitanium dioxide. Nzvimbo yekuvira yerutile titanium dioxide ndeye (3200 ivhu 300) K, uye titanium dioxide inoputika zvishoma pakupisa uku.
Nzira
Industrial titanium oxide sulfate inonyungudika mumvura uye inosefa. Ammonia yakawedzerwa kuti iwedzere gauntlet-yakafanana nemvura, uye yobva yapepetwa. Zvadaro inonyungudutswa ne oxalic acid solution, uye yobva yanatswa uye inosefa neammonia. Mvura yakawanikwa inoomeswa pa170 ° C uye yogochwa pa540 ° C kuti iwane pure titanium dioxide.
Mizhinji yacho migodhi yakavhurika. Titanium primary ore beneficiation inogona kupatsanurwa kuita matanho matatu: pre-separation (inowanzo shandiswa magineti kupatsanurwa uye gravity separation method), iron separation (magnetic separation method), uye titanium separation (gravity separation, magnetic separation, electric separation and flotation method). Kubatsirwa kwetitanium zirconium placers (kunyanya vanoisa pamahombekombe, vachiteverwa nevari mukati menyika) vanogona kukamurwa kuita matanho maviri: kupatsanurwa kwakashata uye kusarudzwa. Muna 1995, Zhengzhou Comprehensive Utilization Research Institute yeBazi reGeology neMineral Resources yakatora maitiro ekuparadzanisa magineti, kupatsanurwa kwesimba rinokwevera pasi uye acid leaching kuti ibatsire mugodhi mukuru werutile muXixia, Henan Province, iyo yakapfuura kugadzirwa kwekuyedza, uye. zviratidzo zvose zviri padanho rinotungamirira muChina.
use
Inoshandiswa se spectral analysis reagent, kugadzirira kwepamusoro-kuchena titanium munyu, pigments, polyethylene colorants, uye abrasives. Inoshandiswawo muindasitiri yemishonga, capacitive dielectric, yakakwirira-tembiricha inodzivirira alloys, uye yakakwirira-tembiricha inodzivirira titanium sponge kugadzira.
Inoshandiswa kugadzira titanium dioxide, titanium sponge, titanium alloy, artificial rutile, titanium tetrachloride, titanium sulfate, potassium fluorotitanate, aluminium titanium chloride, etc. , machira, welding electrodes uye rayon light-reducing agents, mapurasitiki uye epamusoro-giredhi mapepa mafirita, uye anoshandiswawo mumidziyo yekufonera, metallurgy, kudhinda, kudhinda uye dhayi, enamel nemamwe madhipatimendi. Rutile zvakare ndiyo huru mineral raw material yekunatsa titanium. Titanium nema alloys ayo ane zvinhu zvakanakisa senge kusimba kwepamusoro, kuderera kwehudhirosi, corrosion resistance, tembiricha yakakwira, kudzikira tembiricha kuramba, kwete-chepfu, nezvimwewo, uye ine mabasa akakosha akadai sekunyudza gasi uye superconductivity, saka anoshandiswa zvakanyanya ndege, indasitiri yemakemikari, indasitiri yemwenje, kufamba, kurapwa, kudzivirira kwenyika uye kuvandudza zviwanikwa zvemugungwa uye mamwe minda. Zvinopfuura 90% zvepasi rose zvicherwa zvetitanium zvinoshandiswa kugadzira titanium dioxide chena pigments, uye chigadzirwa ichi chinoshandiswa zvakanyanya mupendi, rabha, mapurasitiki, mapepa uye mamwe maindasitiri.
kuchengeteka
Chengetedza muimba yekuchengetera inotonhorera, ine mhepo. Iyo package yakavharwa. Haikwanise kuchengetwa uye yakasanganiswa nemaasidhi.
Rutile mineral zvigadzirwa hazvifanirwe kusanganiswa nekunze kwenyika mukuita kurongedza, kuchengetedza uye kutakura. Iyo yekurongedza bhegi zvinhu inodiwa kuti isaita ngura uye isiri nyore kuputsika. Kaviri-layer bag packaging, mukati nekunze kwemukati kunofanirwa kufananidzwa, mukati memukati ipurasitiki bhegi kana jira bhegi (kraft bepa rinogona kushandiswawo), uye kunze kwekunze ibhegi rakarukwa. Huremu hwepasuru yega yega i25kg kana 50kg. Paunenge uchitakura, muromo webhegi unofanira kuvharwa zvakasimba, uye logo pahomwe inofanira kuva yakasimba, uye kunyora kunofanira kujeka uye kusapera. Imwe neimwe batch yezvigadzirwa zvemamineral ichaperekedzwa nechitupa chemhando inosangana nezvinodiwa zvechiyero. Kuchengetwa kwezvigadzirwa zvemamineral kunofanirwa kuiswa mumagiredhi akasiyana, uye nzvimbo yekuchengetera inofanirwa kuve yakachena.
