Trivarent chromium vs. Hexavalent chromium

1. Maitiro emakemikari:

• Triviment chromium (Cr(III)):
  • Zvisikwa: Zvakasarudzika kuitika, inowanzoonekwa seyakaderera ine chepfu.
  • Oxidation nyika: Chromium iripo mu +3 oxidation nyika.
• Hexavalent chromium (Cr(Vi)):
  • Zvisikwa: Kazhinji inayo maindasitiri, inozivikanwa neyakaipfuura.
  • Oxidation nyika: Chromium iripo mu +6 oxidation nyika.

2. Hutano uye nemamiriro ekunze:

• Triviment chromium:
  • Hutano hwehutano: Kazhinji inoonekwa seisina kukuvadza kune hutano hwevanhu.
  • Kukanganisa kwezvakatipoteredza: Inoisa njodzi dzemamiriro ekunze.
• Hexavalent chromium:
  • Hutano hwehutano: Inozivikanwa neyakaipfuura, yakabatana nenyaya dzekufema uye dzeganda.
  • Kukanganisa kwezvakatipoteredza: Zvine njodzi, uye inoisa njodzi huru kune ecosystems.

3. Indasitiri yekushandisa uye mashandisiro:

• Triviment chromium:
  • Applications: Inowanzo shandiswa mukushongedza chreme plating, Kuzeya Maitiro, uye zvimwe zvekunyika-corrosion coatings.
• Hexavalent chromium:
  • Applications: Nhoroondo inoshandiswa mune dzakasiyana siyana maindasitiri maitiro, kusanganisira chrome plating, Asi kushandiswa kwayo kunorambidzwa nekuda kwezvinhu zvakatipoteredza uye zvine chekuita nehutano.

4. Zvakanakira uye Zvakashata:

• Triviment chromium:
  • Zvakanakira: Kazhinji inoonekwa seyakagwinya, uye zvimwe zvakatipoteredza hushamwari.
  • Zvinokuvadza: Inogona kunge iine mhedziso mune mamwe maindasitiri ekushandisa nekuda kwekudzikisira kupesana kuenzaniswa neHexavalent chromium.
• Hexavalent chromium:
  • Zvakanakira: Nhoroondo inokosheswa neyakakurisa simba rekumanikidza muindasitiri maitiro.
  • Zvinokuvadza: Highity Thupfu, Mirairo yakasimba inodzikisira kushandiswa kwayo, uye zvakatipoteredza zvinotyisa.

5. Kugadzirwa kwakaoma uye mutengo:

• Triviment chromium:
  • Kugadzirwa kwakaoma: Kufambira mberi muTekinoroji kwakavandudza maitiro ekugadzira, kugadzira trevalent chromium zvakanyanya kuwanikwa.
  • Mutengo: Kazhinji, Mutengo wekugadzira wetatu trombium anokwikwidza.
• Hexavalent chromium:
  • Kugadzirwa kwakaoma: Nhoroondo iri nyore kugadzira, asi mirairo yakasimba yakawedzera kuoma.
  • Mutengo: Kuteerana nemitemo yezvakatipoteredza uye matanho ekuchengetedza akawedzera mutengo wekugadzira.

6. Nzvimbo yekudzora:

• Triviment chromium:
  • Stuulatory Status: Kazhinji inogamuchirwa uye isinganyanyo kudzora nekuda kwekuderera kwehupfu.
• Hexavalent chromium:
  • Stuulatory Status: Yakanyanya kudzora nekuda kwehutano uye zvakatipoteredza zvinokunetsa. Matunhu mazhinji anoisa miganhu yakaoma pakushandisa kwayo.

Mukupedzisa, Sarudzo pakati peThe Travalent uye Hexavalent chromium zvinoenderana nekunyorwa chaiko, kutevedzera kutevedzera kutevedzera, uye kutevedzera zvakatipoteredza. Nepo trivent chromium inowanzoonekwa seyakachengeteka imwe nzira, zvese zvine zvavakanakira uye zvavanogumira, uye indasitiri inoramba ichishanduka ichienda kune mamwe mabasa eshamwari.
