Titanium dioxide, inowanzozivikanwa seTio2, ivara chena rinoshandiswa zvakasiyana-siyana rinoshandiswa mumaindasitiri akasiyana-siyana. Titanium dioxide rutile poda imhando yetitanium dioxide iyo inonyanya kukosha kune yayo yakakwirira refractive index uye yakanakisa mwenje yekuparadzira zvimiro. Kunzwisisa maitiro ekugadzirwa kwerutile titanium dioxide poda yakakosha kune vanogadzira uye vatengi kuti vanzwisise kunaka kwayo uye mashandisirwo.
Kugadzirwa kwerutile titanium dioxide powder kunosanganisira matanho anokosha akawanda, kutanga nekubviswa kwetitanium ore, yakadai seilmenite kana rutile. Aya ores anobva agadziriswa kuti awane pure titanium dioxide, iyo inonatswazve kuti ibudise inodiwa rutile fomu. Izvi zvinotevera mhedziso yekugadzirwa kwetitanium dioxide rutile powder:
1. Kubviswa kwesimbi uye kucheneswa: Danho rekutanga mukugadzirwa kwerutile titanium poda ndeyekubvisa titanium ore kubva mumamineral deposits. Ilmenite uye rutile ndiyo inonyanya kuwanika yetitanium dioxide. Mushure mekunge ore yawanikwa, inofanirwa kupfuura neyakatevedzana yekuchenesa nzira yekubvisa tsvina uye kuwana yakakwirira-kuchena titanium dioxide concentrate.
2. Chlorination uye oxidation: Iyo yakanatswa titanium dioxide concentrate inobva yapinda chlorination process, ichiita neklorini kuita titanium tetrachloride (TiCl4). Komboni yacho inobva yaiswa oxidized kuti ibudise musanganiswa wetitanium dioxide nezvimwe zvinogadzirwa.
3. Hydrolysis and calcination: Musanganiswa unobva waitwa hydrolyzed kuti uwedzere titanium dioxide muchimiro chayo chehydrated. Iyi precipitate inozoverengerwa pakupisa kwakanyanya kubvisa mvura uye kuishandura kuita inodiwa rutile crystal chimiro. Iyo calcination process yakakosha pakuona zvivakwa uye kunaka kwekupedzisirarutile titanium dioxideupfu.
4. Kurapa kwepamusoro: Kuti uvandudze kupararira uye kuenderana kwe rutile titanium dioxide mune zvakasiyana-siyana zvinoshandiswa, kurapwa kwepamusoro kunogona kuitwa. Izvi zvinosanganisira kuvhara pamusoro pezvimedu neinorganic kana organic komisheni kuti vawedzere kuita kwavo uye kugadzikana mumhando dzakasiyana.
5. Kudzora Kwehutano uye Packaging: Mukati yose yekugadzirwa kwezvinhu, maitiro ekugadzirisa hutano anoshandiswa kuti ave nechokwadi chekuchena, kugoverwa kwekukura kwechidimbu uye mamwe maitiro anokosha erutile titanium dioxide powder. Kana poda yasangana nezvinodiwa, inoiswa mukati uye yakagadzirira kugoverwa kune vashandisi vekupedzisira.
Kugadzirwa kwerutile titanium dioxide kunoda kungwarira kutonga kweakasiyana ma paramita, anosanganisira raw material kusarudzwa, process mamiriro uye post-processing nzira. Vagadziri vanoshanda kugadzirisa zvinhu izvi kuti vawane saizi inodiwa, chimiro chekristaro uye zvivakwa zvepasi kuti zvisangane nezvinodiwa zvekushandisa kwakasiyana.
Rutile titanium dioxide poda inoshandiswa zvakanyanya mupendi, machira, mapurasitiki nezvimwe zvigadzirwa uye inokosheswa nekupenya kwayo kwakanyanya, kupenya uye UV kudzivirira zvivakwa. Nekunzwisisa nzira yekugadzira ye rutile titanium dioxide powder, vagadziri vanogona kugadzirisa zvinhu zvayo kuti vasangane nezvinodiwa zvekushanda kwechigadzirwa chekupedzisira, asi vatengi vanogona kuonga hutano uye kushanda kweiyi yakakosha pigment chena.
Muchidimbu, kugadzirwa kwerutiletitanium dioxide podaInosanganisira nhevedzano yakaoma yematanho kubva pakutorwa kweore kuenda kukurapa kwepamusoro kuti ibudise emhando yepamusoro titanium dioxide pigments ine yakanakisa kuparadzira chiedza. Kunzwisisa uku kwakakosha kuti vagadziri uye vashandisi vaone kugona kwakazara kwetitanium dioxide rutile poda mumashandisirwo akasiyana.
