zinc tshauv tsim li cas, thiab nws cov khoom yog dab tsi?

Zinc tshauv, tseem hu ua zinc oxide, tsim sai heev thaum lub sij hawm kub-dip galvanizing, qhov tseem ceeb regenerating tam sim ntawd tom qab txhua scraping vim yog tam sim no cov tshuaj tiv thaiv ntawm molten zinc hlau thiab oxygen nyob rau hauv cov huab cua, ua zinc oxide. Tsis tas li ntawd, thaum cov kuab tshuaj ntawm cov yeeb nkab steel yuav tsum tau galvanized yog immersed nyob rau hauv zinc molten, nws activates lub adsorption ntawm zinc mus rau lub hlau nto, nrog rau ib tug phiv ntawm kev tsim ib co zinc tshauv thiab hnyav residue. Zinc tshauv feem ntau yog tsim los ntawm kev sib xyaw ntawm zinc oxide, nws yog xim hlau zinc hais, chlorides, thiab lwm yam acid-insoluble impurities. Cov zinc oxide nyob rau hauv zinc tshauv yog ib feem ntawm zinc oxide ntshiab thiab ib nrab ua ke nrog lwm cov oxides. Cov hlau zinc me me feem ntau suav rau 15-35% ntawm tag nrho cov zinc tshauv. Nyob ntawm cov cuab yeej siv rau khawb cov tshauv, qhov feem pua ​​​​ntawm no tuaj yeem ncav cuag 30-60%, thiab qee zaum, txawm tias 70-75%.
