1. Karolo ea titanium dioxide ka liaparo
Liaparo li entsoe haholo ka likarolo tse 'nè: lintho tse etsang filimi, li-pigments, li-solvents le li-additives.Li-pigments tse koahetsoeng li na le matla a itseng a ho pata.E ke ke ea koahela feela 'mala oa pele oa ntho e koahetsoeng, empa hape e fana ka seaparo sa' mala o khanyang.Lemoha phello e khabisitsoeng ea mabone le botle.Ka nako e ts'oanang, pigment e kopantsoe haufi-ufi le moemeli ea folisang le substrate, 'me e kopantsoe, e ka matlafatsa matla a mochine le ho khomarela filimi ea ho roala, ho thibela ho phunyeha kapa ho oa,' me e ka eketsa botenya ba filimi ea ho roala, e thibelang ho phatloha kapa ho oela. ho kenella ha mahlaseli a ultraviolet kapa mongobo, le ho ntlafatsa ho roala.Lintho tse khahlanong le botsofali le ho tšoarella ha filimi li eketsa bophelo ba tšebeletso ea filimi le ntho e sirelelitsoeng.
Ka 'mala, palo ea 'mala o mosoeu e kholo haholo,' me litlhoko tsa ts'ebetso ea ho roala ha 'mala o mosoeu: ①Bosoeu bo botle;②Ho sila hantle le ho ba metsi;③Ho hanyetsa boemo ba leholimo bo botle;④Botsitso bo botle ba lik'hemik'hale;⑤Bongata bo bonyenyane, matla a ho pata le tahlehelo Matla a 'mala a phahameng, opacity e ntle le gloss.
Titanium dioxide ke mofuta oa pigment e tšoeu e sebelisoang haholo ho roala.Sehlahisoa sa eona se etsa karolo e fetang 70% ea li-pigments tse sa tloaelehang, 'me tšebeliso ea eona e etsa 95.5% ea kakaretso ea tšebeliso ea mebala e tšoeu.Hajoale, hoo e ka bang 60% ea titanium dioxide ea lefats'e e sebelisoa ho etsa liphahlo tse fapaneng, haholo-holo rutile titanium dioxide, eo boholo ba eona e jeoang ke indasteri ea ho roala.Pente e entsoeng ka titanium dioxide e na le mebala e khanyang, matla a phahameng a ho pata, matla a matla a ho penya, tekanyo e tlaase le mefuta e mengata.E sireletsa botsitso ba seaplane, 'me e ka matlafatsa matla a mochine le ho khomarela filimi ea pente, ho thibela mapetsong, le ho thibela mahlaseli a ultraviolet.E kenella ka metsi 'me e lelefatsa bophelo ba filimi ea pente.'Mala o tšoanang oa hoo e batlang e le paterone e' ngoe le e 'ngoe ea pente e mebala-bala ha o arohane le titanium dioxide.
Mefuta e fapaneng ea liphahlo bakeng sa merero e fapaneng e na le litlhoko tse fapaneng tsa titanium dioxide.Ka mohlala, ho roala phofo ho hloka hore ho sebelisoe rutile titanium dioxide e nang le dispersibility e ntle.Anatase titanium dioxide e na le matla a tlase a decoloring le ts'ebetso e matla ea lik'hemik'hale.Ha e sebelisoa ka liaparo tsa phofo, filimi ea ho roala e atisa ho ba mosehla.Rutile titanium dioxide e hlahisoang ke mokhoa oa sulfuric acid e na le melemo ea theko e itekanetseng, ho hasana hantle, matla a ho ipata a matle le matla a ho fokotsa mebala, 'me e loketse haholo bakeng sa ho roala phofo ka hare ho ntlo.Ntle le dispersibility e ntle, matla a ho pata le matla a ho fokotsa mebala, titanium dioxide bakeng sa liaparo tsa ka ntle tsa phofo e boetse e hloka boemo ba leholimo bo botle.Ka hona, phofo ea titanium bakeng sa liaparo tsa ka ntle tsa phofo hangata ke rutile titanium dioxide e hlahisoang ke chlorination.
2. Tlhahlobo ea phello ea liphetoho tse ka sehloohong tsa boleng ba titanium dioxide holim'a liaparo
1 bosoeu
Titanium dioxide e sebelisoa e le pigment e tšoeu bakeng sa ho roala.Bosoeu ba eona bo bohlokoa haholo 'me ke e' ngoe ea matšoao a bohlokoa a boleng bo hlokoang ke ho roala.Bosoeu bo bobe ba titanium dioxide bo tla ama ka ho toba ponahalo ea filimi ea ho roala.Ntho e ka sehloohong e amang bosoeu ba titanium dioxide ke mofuta le litaba tsa litšila tse kotsi, hobane titanium dioxide e na le kutloelo-bohloko haholo ho litšila, haholo-holo rutile titanium dioxide.
Ka hona, esita le litšila tse nyane li tla ba le tšusumetso e kholo ho bosoeu ba titanium dioxide.Bosoeu ba titanium dioxide e hlahisoang ke ts'ebetso ea chloride hangata bo molemo ho feta bo hlahisoang ke ts'ebetso ea sulfuric acid.Lebaka ke hobane thepa e tala ea titanium tetrachloride e sebelisoang tlhahiso ea titanium dioxide ka ts'ebetso ea chloride e hloekisitsoe le ho hloekisoa, 'me litšila tsa eona li fokotsehile, ha ts'ebetso ea sulfuric acid e sebelisa Thepa e tala e na le lintho tse ngata tse sa hloekang, tse ka khonang feela. ho ntšoa ka mekhoa ea ho hlatsoa le ho soeufatsa.
2 matla a ho pata
Matla a ho pata ke sebaka se kaholimo sa ntho e koahetsoeng ka lisenthimithara tse 'ngoe.Ha e koahetsoe ka ho feletseng, sebaka se le seng se pentiloe.Ha matla a ho pata a titanium dioxide a sebelisitsoeng, filimi ea ho roala e ka ba mosesaane, 'me pente e fokolang e hlokahalang, e nyenyane palo ea titanium dioxide e hlokahalang, haeba matla a ho pata a titanium dioxide a fokotseha, e le hore a fokotsehe. finyella phello e tšoanang ea ho koahela, palo ea titanium dioxide e hlokahalang e eketseha, litšenyehelo tsa tlhahiso li tla eketseha, 'me ho eketseha ha palo ea titanium dioxide ho tla etsa hore titanium dioxide e be teng ka ho roala Ho thata ho qhala ka mokhoa o ts'oanang,' me ho kopanya ho etsahala, ho tla e boetse e ama phello ea sekoahelo sa ho roala.
3 ho hanyetsa boemo ba leholimo
Liaparo li hloka ho hanyetsa boemo ba leholimo bo phahameng ba titanium dioxide, haholo-holo bakeng sa liphahlo tse ka ntle, tse hlokang ho hanyetsa boemo ba leholimo bo phahameng kapa ho hanyetsa maemo a leholimo a phahameng haholo.E sebelisa titanium dioxide e thibelang boemo ba leholimo bo fokolang, filimi ea ho roala e tla ba le mathata a kang ho fela, ho fifala, ho chekoa, ho petsoha le ho ebola.Sebopeho sa kristale sa rutile titanium dioxide se matla ho feta sa anatase titanium dioxide, 'me mosebetsi oa eona oa photochemical o tlaase.Ka hona, khanyetso ea boemo ba leholimo e phahame haholo ho feta ea anatase titanium dioxide.Ka hona, titanium dioxide e sebelisetsoang ho roala ha e le hantle ke rutile titanium dioxide.Mokhoa o ka sehloohong oa ho ntlafatsa khanyetso ea boemo ba leholimo ba titanium dioxide ke ho etsa kalafo ea inorganic holim'a metsi, ke hore, ho koahela karolo e le 'ngoe kapa ho feta ea inorganic oxides kapa hydrated oxides holim'a likaroloana tsa titanium dioxide.
4 hasane
Titanium dioxide ke likaroloana tse ntle haholo tse nang le sebaka se seholo se ikhethileng le matla a holimo.Ho bonolo ho kopanya pakeng tsa likaroloana 'me ho thata ho hasanya ka mokhoa o tsitsitseng ka liphahlo.Ho qhalakanngoa ho futsanehileng ha titanium dioxide ho tla ama ka ho toba thepa ea eona ea optical e kang ho fokotsa mebala, matla a ho pata le khanya ea holim'a seaparo, hape e ama botsitso ba polokelo, metsi, ho lekana, ho tšoarella ha moaparo, le ho hanyetsa ha kutu ea ho roala.Thepa ea kopo e joalo ka conductivity ea motlakase le conductivity e tla ama litšenyehelo tsa tlhahiso ea liphahlo, hobane ts'ebeliso ea matla ea ts'ebetso ea ho sila le ea ho hasana e phahame, e ikarabellang bakeng sa boholo ba tšebeliso ea matla a ts'ebetso ea ho etsa liaparo, 'me tahlehelo ea lisebelisoa e kholo. .
Tlhokahalo ea titanium dioxide e ntse e eketseha selemong sena, haholo-holo bakeng sa titanium dioxide e sebelisoang indastering ea lifofane ea lithium-ion, e ntseng e tlameha ho itšetleha ka thepa e tsoang kantle ho naha.E le karolo e ka tlaase ea titanium dioxide, liphahlo li angoa ke sefefo sa tikoloho, 'me palo e kholo ea likhoebo tse nyenyane le tse mahareng li koetsoe.Nakong e tlang, palo ea titanium dioxide 'marakeng oa liaparo le eona e tla fokotseha.
