Rudzi Rwakasiyana
Titanium dioxide chinhu chisina kugadzirwa chemakemikari, chinoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri senge machira, mapurasitiki, rabha, kugadzira mapepa, inki dzekudhinda, fiber dzemakemikari, uye zvizoro. Titanium dioxide ine mafomu maviri ekristaro: rutile neanatase. Rutile titanium dioxide, kureva R-type titanium dioxide; anatase titanium dioxide, kureva A-type titanium dioxide.
Rutile titanium dioxide ine hunhu hwakanaka hwakadai sekudzivirira kupisa kwakanyanya, kudzivirira kupisa kwakaderera, kudzivirira ngura, simba guru, uye simba diki rekukweva. Kana ichienzaniswa neanatase titanium dioxide, ine simba guru rekudzivirira mamiriro ekunze uye inoshanda zviri nani ne photooxidative activity. Rutile type (R type) ine density ye4.26g/cm3 uye refractive index ye2.72. R-type titanium dioxide ine hunhu hwekudzivirira mamiriro ekunze kwakanaka, kudzivirira mvura uye hazviremi kutsvukira. Rutile titanium dioxide ine mabhenefiti akawanda mukushandiswa kwakasiyana-siyana. Semuenzaniso, nekuda kwechimiro chayo, pigment yainogadzira yakagadzikana muruvara uye iri nyore kuisa ruvara. Ine kugona kwakasimba kwekupenda uye haikuvadzi pamusoro pepamusoro. Inoisa ruvara pakati, uye ruvara rwakajeka, haruna kunyangarika nyore. -
Anatase
Titanium dioxide chinhu chisina kugadzirwa chemakemikari, chinoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri senge machira, mapurasitiki, rabha, kugadzira mapepa, inki dzekudhinda, fiber dzemakemikari, uye zvizoro. Titanium dioxide ine mafomu maviri ekristaro: rutile neanatase. Rutile titanium dioxide, kureva R-type titanium dioxide; anatase titanium dioxide, kureva A-type titanium dioxide.
Titanium dioxide yerudzi rwetitanium ndeye titanium dioxide yemhando yepigment, ine hunhu hwekuvanza simba rakasimba, simba rekuisa ruvara rwakanyanya, kudzivirira kukwegura uye kuramba mamiriro ekunze akanaka. Anatase titanium dioxide, zita remakemikari titanium dioxide, molecular formula Ti02, molecular weight 79.88. Upfu huchena, huwandu hwehukama 3.84. Kugara kwenguva refu hakuna kunaka se rutile titanium dioxide, kuramba chiedza kwakaderera, uye adhesive layer iri nyore kupwanywa mushure mekusanganiswa ne resin. Nokudaro, inowanzo shandiswa pazvinhu zvemukati, kureva kuti, inonyanya kushandiswa kune zvigadzirwa zvisingapfuure nechiedza chezuva chakananga.
