Umgubo weChromium ngumgubo wesinyithi oqhelekileyo, osetyenziswa ikakhulu ekwenzeni udidi oluphezulu lwamandla, i-alloys enganyangekiyo kwi-corrosion kunye neemveliso.

Ukuqaliswa kwechromium powder

I-Chromium powder yintsimbi yentsimbi eyenziwe ngechromium, i-molecular formula yi-Cr, ubunzima be-molecular yi-51.99.Inembonakalo entle, egudileyo, isilivere emhlophe okanye ingwevu, inzima kakhulu.I-Chromium powder ngumgubo wentsimbi obalulekileyo, osetyenziswa kakhulu kwimveliso, i-electronics, i-aerospace kunye nezinye iindawo.

Iimpawu zomzimba kunye neekhemikhali zechromium powder

Iimpawu ezibonakalayo zechromium powder zibandakanya ukuxinana okuphezulu, ukuhanjiswa kombane okulungileyo kunye nokuxhathisa ukubola.Inobunzima be-7.2g / cm3, indawo yokunyibilika ye-1857 ° C kunye neqondo lokubilisa lika-2672 ° C. I-Chromium powder ayilula ukuba i-oxidize kwiqondo lokushisa, inokumelana ne-corrosion egqwesileyo, inokumelana ne-asidi, i-alkali, ityuwa kunye ezinye iikhemikhali izinto umhlwa.

Iimpawu zeekhemikhali zechromium powder ziyasebenza kwaye zinokusabela ngezinto ezahlukeneyo zekhemikhali.Umzekelo, umgubo wechromium unokusabela ngamanzi ukwenza i-chromium hydroxide kwaye ikhuphe i-hydrogen.Ukongeza, i-chromium powder inokusabela ngee-oxidants ezininzi kwaye ifakwe i-oxidized kwi-ion ze-chromium ezintathu.

Ukulungiselela indlela yomgubo wechromium

Iindlela zokulungiselela i-chromium powder ikakhulu ziquka indlela ye-electrolysis, indlela yokunciphisa kunye nendlela ye-oxidation.I-Electrolysis yindlela eqhelekileyo yokulungiselela ukufumana i-chromium powder nge-electrolysis yesisombululo setyuwa ye-chromium kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu.Indlela yokunciphisa kukusabela i-chromium ore kunye nekhabhoni kwiqondo lokushisa eliphezulu ukuvelisa i-chromium carbide, kwaye emva koko uyityumze ukufumana i-chromium powder.Indlela ye-oxidation yindlela yokunciphisa i-chromium oxide kwiqondo lokushisa eliphezulu ukuvelisa i-chromium powder.Iindlela ezahlukeneyo zineenzuzo ezahlukeneyo kunye nokungonakali, kwaye indlela efanelekileyo yokulungiselela kufuneka ikhethwe ngokweemfuno.

Iindawo zokusetyenziswa kwechromium powder

Imimandla yesicelo somgubo wechromium ibanzi kakhulu, ngakumbi ibandakanya ukusetyenzwa kwesinyithi esingeyontsimbi, izixhobo zokwakha, ukunyangwa kwangaphambili, ishishini lebhetri njalo njalo.Kwintsimi ye-metal processing metal, i-chromium powder ingasetyenziselwa ukuvelisa ubuninzi obuphezulu, i-alloys-resistant-resistant alloys kunye neemveliso, ezifana nensimbi engenasici, insimbi yesixhobo, isinyithi esinesantya esiphezulu njalo njalo.Kumhlaba wezinto zokwakha, umgubo wechromium unokusetyenziselwa ukwenza iintlobo ngeentlobo ze-corrosion-resistant, ubushushu obuphezulu be-ceramic kunye neemveliso zeglasi.Kwintsimi yonyango lwangaphambili, umgubo wechromium unokusetyenziselwa ukwenza iiarhente zokuguqula iikhemikhali ezahlukeneyo, ezinjengee-agent zokuguqula i-chromate kunye nee-agent zokuguqula i-phosphate.Kwishishini lebhetri, umgubo wechromium unokusetyenziselwa ukwenza izinto ezahlukeneyo zebhetri ze-electrode, ezinjengeebhetri zenickel-cadmium kunye neebhetri zenickel-metal hydride.

Ukhuseleko lwe-chromium powder kunye nokukhuselwa kwendalo

I-Chromium powder yinto enobungozi, ukuvezwa kwexesha elide kunokubangela ukucaphuka kunye nokulimala kwesikhumba somntu, amehlo kunye nenkqubo yokuphefumula, kwaye kwiimeko ezinzima kunokukhokelela kumhlaza.Ngoko ke, kwimveliso, ukusetyenziswa kunye nokuphathwa kwe-chromium powder, kuyimfuneko ukuthobela ngokuthe ngqo iinkqubo ezifanelekileyo zokusebenza zokhuseleko kunye nemimiselo yokusingqongileyo.Kwangaxeshanye, iindlela ezifanelekileyo zokulahla inkunkuma, njengokungcwatywa nzulu, ukutshiswa okanye ukunyangwa kweekhemikhali, kufuneka zisetyenziswe ukunciphisa impembelelo kokusingqongileyo nakwimpilo yabantu.

Ngamafutshane, i-chromium powder iyipowder yensimbi ebalulekileyo, eneendlela ezininzi zokusetyenziswa kunye nexabiso elibalulekileyo lezoqoqosho.Emva kokuqonda iimpawu zayo ezisisiseko, iindlela zokulungiselela, imimandla yesicelo kunye nokhuseleko kunye nemiba yokukhuselwa kwendalo, sinokuqonda ngakumbi ulwazi oluhambelanayo kunye nokusetyenziswa kwayo.Ngexesha elifanayo, kufuneka sinikele ingqalelo ekukhuselweni kwendalo kunye nempilo yabantu, kwaye sinciphise impembelelo kwindalo kunye nabantu.
