Kenyelletso ea phofo ea chromium

Chromium phofo ke phofo ea tšepe e entsoeng ka chromium, foromo ea molek'hule ke Cr, boima ba molek'hule ke 51.99.E na le ponahalo e ntle, e boreleli, silevera e tšoeu kapa e bohlooho, e thata haholo.Chromium phofo ke phofo ea bohlokoa ea tšepe, e sebelisoang haholo ho etsa thepa, lisebelisoa tsa elektroniki, sefofane le masimo a mang.

Lintho tsa 'mele le tsa lik'hemik'hale tsa phofo ea chromium

Thepa ea 'mele ea phofo ea chromium e kenyelletsa letsoalo le phahameng, conductivity e ntle ea motlakase le ho hanyetsa kutu.E na le boima ba 7.2g / cm3, ntlha ea ho qhibiliha ea 1857 ° C le ntlha e belang ea 2672 ° C. Chromium phofo ha e bonolo ho oxidize mocheso oa kamore, e na le khanyetso e ntle ea kutu, e ka hanyetsa acid, alkali, letsoai le lintho tse ling tsa lik'hemik'hale ho bola.

Lik'hemik'hale tsa phofo ea chromium li batla li le mafolofolo 'me li ka itšoara ka mefuta e sa tšoaneng ea lik'hemik'hale.Ka mohlala, phofo ea chromium e ka itšoara ka metsi ho etsa chromium hydroxide le ho ntša hydrogen.Ho feta moo, phofo ea chromium e ka sebetsana le li-oxidants tse ngata 'me ea e-ba oxidized ho li-ion tse tharo tsa chromium.

Mokhoa oa ho itokisa oa phofo ea chromium

Mekhoa ea ho itokisa ea phofo ea chromium haholo-holo e kenyelletsa mokhoa oa electrolysis, mokhoa oa ho fokotsa le mokhoa oa oxidation.Electrolysis ke mokhoa o tloaelehileng oa ho itokisa ho fumana phofo ea chromium ka electrolysis ea tharollo ea letsoai la chromium ka mocheso o phahameng le khatello e phahameng.Mokhoa oa phokotso ke ho sebetsana le ore ea chromium le carbon ka mocheso o phahameng ho hlahisa chromium carbide, ebe o e pshatla ho fumana phofo ea chromium.Mokhoa oa oxidation ke karabelo ea phokotso ea chromium oxide mochesong o phahameng ho hlahisa phofo ea chromium.Mekhoa e sa tšoaneng e na le melemo le mathata a sa tšoaneng, 'me mokhoa o loketseng oa ho lokisetsa o lokela ho khethoa ho latela litlhoko.

Masimo a kopo ea phofo ea chromium a pharaletse haholo, haholo-holo a kenyelletsa ts'ebetso ea tšepe e se nang ferrous, thepa ea kaho, pretreatment ea ho roala, indasteri ea betri joalo-joalo.Lefapheng la ts'ebetso ea tšepe e se nang ferrous, phofo ea chromium e ka sebelisoa ho etsa mefuta e sa tšoaneng ea matla a phahameng, li-alloys tse thibelang kutu le lihlahisoa, tse kang tšepe e sa hloekang, tšepe ea lisebelisoa, tšepe e phahameng le tse ling.Lefapheng la thepa ea kaho, phofo ea chromium e ka sebelisoa ho etsa mefuta e fapaneng ea lihlahisoa tse sa jeng, tse nang le mocheso o phahameng oa mocheso le lihlahisoa tsa khalase.Lebaleng la ho koaheloa esale pele, phofo ea chromium e ka sebelisoa ho etsa lisebelisoa tse fapaneng tsa phetoho ea lik'hemik'hale, joalo ka li-conversion agents tsa chromate le li-conversion agents tsa phosphate.Indastering ea betri, phofo ea chromium e ka sebelisoa ho etsa lisebelisoa tse fapaneng tsa li-electrode tsa betri, joalo ka libeteri tsa nickel-cadmium le libeteri tsa nickel-metal hydride.

Tšireletseho ea phofo ea Chromium le tšireletso ea tikoloho

Chromium phofo ke ntho e kotsi, ho pepeseha ha nako e telele ho ka baka ho teneha le ho senya letlalo la motho, mahlo le tsamaiso ea ho hema, 'me maemong a matla ho ka lebisa mofetšeng.Ka hona, ha ho etsoa, ​​​​ho sebelisoa le ho sebetsana le phofo ea chromium, hoa hlokahala ho latela ka tieo mekhoa e nepahetseng ea ts'ebetso ea ts'ireletso le melaoana ea tikoloho.Ka nako e ts'oanang, mekhoa e nepahetseng ea ho lahla litšila, joalo ka ho pata ho tebileng, ho chesoa kapa ho phekola ka lik'hemik'hale, e lokela ho sebelisoa ho fokotsa tšusumetso tikolohong le bophelong ba batho.

Ka bokhutšoanyane, phofo ea chromium ke phofo ea tšepe ea bohlokoa, e nang le mefuta e mengata ea tšebeliso le boleng ba bohlokoa ba moruo.Kamora ho utloisisa thepa ea eona ea mantlha, mekhoa ea ho itokisa, masimo a kopo le litaba tsa polokeho le ts'ireletso ea tikoloho, re ka utloisisa hamolemo tsebo le ts'ebeliso ea eona.Ka nako e ts'oanang, re boetse re lokela ho ela hloko ts'ireletso ea tikoloho le bophelo bo botle ba batho, le ho fokotsa tšusumetso ea tikoloho le batho.
