Chromium poda yakajairika simbi hupfu, inonyanya kushandiswa mukugadzira akasiyana-siyana epamusoro-simba, anodzivirira corrosion alloys uye zvigadzirwa.

Kutanga kwechromium poda

Chromium poda isimbi yakagadzirwa nechromium, iyo molecular formula ndeye Cr, iyo molecular uremu i51.99.Iine chitarisiko chakanaka, chakatsetseka, sirivha chena kana grey, yakaoma zvikuru.Chromium poda yakakosha simbi hupfu, iyo inoshandiswa zvakanyanya mukugadzira, zvemagetsi, aerospace uye mamwe minda.

Zvenyama uye zvemakemikari zvimiro zvechromium poda

Hunhu hwemuviri hwechromium hupfu hunosanganisira kusimba kwepamusoro, kunaka kwemagetsi conductivity uye kushomeka kwekudzivirira.Iine density ye 7.2g/cm3, kunyunguduka kwe1857 ° C uye kuvira kwe2672 ° C. Chromium powder haisi nyore kuisa oxidize pakupisa kwekamuri, ine yakanakisa corrosion resistance, inogona kuramba asidi, alkali, munyu uye. zvimwe makemikari zvinhu ngura.

Iyo kemikari yechromium poda inoshanda uye inogona kuita neakasiyana emakemikari zvinhu.Semuenzaniso, chromium poda inogona kuita nemvura kuti igadzire chromium hydroxide uye kupa hydrogen.Pamusoro pezvo, chromium poda inogona kuita neakawanda oxidants uye kuve oxidized kune trivalent chromium ions.

Kugadzirira nzira yechromium poda

Nzira dzekugadzirira chromium poda dzinonyanya kusanganisira electrolysis nzira, kuderedza nzira uye oxidation nzira.Electrolysis inzira yakajairika yekugadzirira kuwana chromium poda ne electrolysis yechromium munyu mhinduro pakupisa kwakanyanya uye kudzvanywa.Nzira yekudzikisa ndeyekuita chromium ore nekabhoni pakupisa kwepamusoro kugadzira chromium carbide, wobva waipwanya kuti uwane chromium poda.Iyo oxidation nzira ndeyekudzikisa maitiro echromium oxide pakupisa kwepamusoro kugadzira chromium poda.Nzira dzakasiyana-siyana dzine zvakanakira zvakasiyana uye zvisingabatsiri, uye nzira yekugadzirira yakakodzera inofanira kusarudzwa maererano nezvinodiwa.

Nzvimbo dzekushandisa dzechromium poda

Iyo minda yekushandisa yechromium poda yakakura kwazvo, kunyanya kusanganisira isiri-ferrous simbi kugadzirisa, zvekuvakisa, coating pretreatment, bhatiri indasitiri uye zvichingodaro.Mumunda wesimbi isina-ferrous metal processing, chromium powder inogona kushandiswa kugadzira zvakasiyana-siyana zvepamusoro-soro, zvigadziriswe zvinopisa uye zvigadzirwa, zvakadai sesimbi isina tsvina, simbi yezvishandiso, simbi yepamusoro-soro nezvimwe zvakadaro.Mumunda wezvivakwa zvekuvaka, chromium poda inogona kushandiswa kugadzira akasiyana-siyana asingadziviriri, akakwira-tembiricha ceramic uye magirazi zvigadzirwa.Mumunda wekupfekedza pretreatment, chromium poda inogona kushandiswa kugadzira akasiyana makemikari ekushandura maajenti, senge chromate inoshandura vamiririri uye phosphate inoshandura vamiririri.Muindasitiri yemabhatiri, chromium poda inogona kushandiswa kugadzira akasiyana mabhatiri emagetsi emagetsi, senge nickel-cadmium mabhatiri uye nickel-metal hydride mabhatiri.

Chromium poda kuchengetedza uye kuchengetedza kwezvakatipoteredza

Chromium poda chinhu chine njodzi, kuratidzwa kwenguva refu kunogona kukonzera kutsamwisa uye kukuvadzwa kweganda remunhu, maziso uye kufema system, uye mumatambudziko akaomarara anogona kukonzera cancer.Naizvozvo, mukugadzira, kushandiswa uye kubata kwechromium poda, zvinodikanwa kunyatso kuteedzera akakodzera kuchengetedza maitiro ekushandisa uye mirairo yezvakatipoteredza.Panguva imwecheteyo, nzira dzakakodzera dzekurasa tsvina, dzakadai sekuvigwa kwakadzika, kupisa kana kurapwa kwemakemikari, dzinofanirwa kushandiswa kuderedza kukanganisa kwezvakatipoteredza uye hutano hwevanhu.

Muchidimbu, chromium powder inokosha yesimbi poda, ine huwandu hwakawanda hwekushandisa uye kukosha kwehupfumi hunokosha.Mushure mekunzwisisa ayo ekutanga zvivakwa, nzira dzekugadzirira, minda yekushandisa uye chengetedzo uye nyaya dzekuchengetedza kwezvakatipoteredza, isu tinogona kunzwisisa zviri nani ruzivo rwayo uye mashandisiro.Panguva imwecheteyo, isu tinofanirawo kutarisisa kuchengetedzwa kwezvakatipoteredza uye hutano hwevanhu, uye kuderedza kukanganisa kwezvakatipoteredza uye vanhu.
