I-Chromium powder iyimpushana yensimbi evamile, esetshenziswa ikakhulukazi ekwenzeni izinhlobonhlobo zamandla aphezulu, ama-alloys angagqwali kanye nemikhiqizo.

Ukwethulwa kwe-chromium powder

I-Chromium powder iyimpushana yensimbi eyenziwe nge-chromium, ifomula yamangqamuzana i-Cr, isisindo samangqamuzana singama-51.99.Inobukeka obuhle, obushelelezi, obusiliva obumhlophe noma obumpunga, buqinile kakhulu.I-Chromium powder iyimpushana yensimbi ebalulekile, esetshenziswa kakhulu ekukhiqizeni, e-electronics, emkhathini nakwezinye izinkambu.

Izakhiwo zomzimba nezamakhemikhali ze-chromium powder

Izinto ezibonakalayo ze-chromium powder zihlanganisa ukuminyana okuphezulu, ukuqhutshwa kahle kukagesi kanye nokumelana nokugqwala.Inobukhulu obungu-7.2g/cm3, indawo yokuncibilika engu-1857 ° C kanye nephuzu elibilayo elingu-2672 ° C. I-Chromium powder akulula ukuyi-oxidize ekamelweni lokushisa, inokumelana nokugqwala okuhle kakhulu, ingamelana ne-asidi, i-alkali, usawoti kanye ezinye izinto zamakhemikhali ukugqwala.

Amakhemikhali e-chromium powder ayasebenza futhi angasabela ngezinto ezihlukahlukene zamakhemikhali.Isibonelo, i-chromium powder ingasabela emanzini ukuze yakhe i-chromium hydroxide futhi ikhiphe i-hydrogen.Ngaphezu kwalokho, i-chromium powder ingasabela ngama-oxidants amaningi futhi ifakwe i-oxidized kuma-ion e-chromium e-trivalent.

Ukulungiselela indlela ye-chromium powder

Izindlela zokulungiselela ze-chromium powder ikakhulukazi zihlanganisa indlela ye-electrolysis, indlela yokunciphisa kanye nendlela ye-oxidation.I-Electrolysis iyindlela evamile yokulungiselela ukuthola i-chromium powder nge-electrolysis yesisombululo sikasawoti se-chromium ekushiseni okuphezulu nokucindezela okukhulu.Indlela yokunciphisa iwukusabela i-chromium ore nekhabhoni ezingeni lokushisa eliphezulu ukukhiqiza i-chromium carbide, bese uyichoboza ukuze uthole impushana ye-chromium.Indlela ye-oxidation ukusabela kokunciphisa kwe-chromium oxide ekushiseni okuphezulu ukukhiqiza impushana ye-chromium.Izindlela ezihlukahlukene zinezinzuzo nezinkinga ezihlukahlukene, futhi indlela efanele yokulungiselela kufanele ikhethwe ngokuvumelana nezidingo.

Izindawo zokusebenzisa i-chromium powder

Izinkambu zokufaka isicelo ze-chromium powder zibanzi kakhulu, ikakhulukazi ezihlanganisa ukucubungula kwensimbi okungeyona ayoni, izinto zokwakha, ukunakekelwa kwangaphambili kokumboza, imboni yebhethri nokunye.Emkhakheni wokucutshungulwa kwensimbi okungeyona insimbi, i-chromium powder ingasetshenziselwa ukwenza ama-alloys anamandla amakhulu, angagqwali kanye nemikhiqizo, njengensimbi engagqwali, insimbi yamathuluzi, insimbi enesivinini nokunye.Emkhakheni wezinto zokwakha, i-chromium powder ingasetshenziswa ukwenza izinhlobonhlobo zemikhiqizo ye-ceramic engagqwali, izinga lokushisa eliphezulu lokushisa eliphezulu kanye nengilazi.Emkhakheni wokwelashwa kwangaphambili kokunamathela, impushana ye-chromium ingasetshenziselwa ukwenza ama-ejenti okuguqula amakhemikhali ahlukahlukene, njengama-ejenti okuguqula i-chromate nama-ejenti okuguqula i-phosphate.Embonini yebhethri, i-chromium powder ingasetshenziswa ukwenza izinto ezihlukahlukene zebhethri ye-electrode, njengamabhethri e-nickel-cadmium namabhethri e-nickel-metal hydride.

Ukuphepha kwe-Chromium powder nokuvikelwa kwemvelo

I-Chromium powder iyinto eyingozi, ukuchayeka isikhathi eside kungabangela ukucasuka nokulimala esikhumbeni somuntu, amehlo kanye nesistimu yokuphefumula, futhi ezimeni ezinzima kungase kubangele umdlavuza.Ngakho-ke, ekukhiqizeni, ekusetshenzisweni nasekuphatheni i-chromium powder, kuyadingeka ukuthobela ngokuqinile izinqubo ezifanele zokusebenza zokuphepha kanye nemithethonqubo yezemvelo.Ngesikhathi esifanayo, izindlela ezifanele zokulahla imfucuza, njengokungcwaba okujulile, ukushiswa noma ukwelashwa ngamakhemikhali, kufanele kusetshenziselwe ukunciphisa umthelela emvelweni nempilo yabantu.

Ngamafuphi, i-chromium powder iyimpushana yensimbi ebalulekile, enezinhlobonhlobo zokusetshenziswa kanye nenani elibalulekile lezomnotho.Ngemva kokuqonda izici zayo eziyisisekelo, izindlela zokulungiselela, izinkambu zokufaka isicelo kanye nezindaba zokuphepha nokuvikelwa kwemvelo, singaluqonda kangcono ulwazi lwayo oluhlobene nokusebenza kwayo.Ngesikhathi esifanayo, kufanele futhi sinake ukuvikelwa kwemvelo kanye nempilo yabantu, futhi sinciphise umthelela emvelweni nakubantu.
