Nws tshwm sim nrog smithsonite, hemimorphite, willemite, cerussite, aurichalcite, calcite thiab limonite.
Hydrozincite nyob qhov twg?
Hydrozincite yog cov pob zeb dav dav thiab ntau yam uas tuaj yeem pom hauv oxidized zinc deposits, feem ntau ntawm cov nuj nqis ntawm sphalerite thiab smithsonite, thiab tseem tuaj yeem pom hauv kuv cov haujlwm thiab qhov tsua. as incrustations.
Hydrozincite ua dab tsi?
Hydrozincite, Zn5(CO3)2(OH) 6, tsis ntev los no tau pom los ua lub luag haujlwm tseem ceeb hauv kev txo cov khoom siv corrosion flaking ntawm Cu–Zn alloys. Txoj kev tshawb fawb tseem ceeb tau ua los tshawb txog cov txheej txheem hauv qab, tshwj xeeb yog vim li cas hydrozincite tuaj yeem cuam tshuam kev cuam tshuam ntawm chlorides thiab cov hlau nplaum.
Hemmorphite nyob qhov twg?
Nws yog txuam nrog lwm cov zinc ores hauv cov hlab ntsha thiab cov txaj hauv limestone thiab tshwm sim hauv ntau cov zinc mines thoob plaws ntiaj teb.
