| Summary: | The influence of the composition of saturating mixtures with standard zinc powder and zinc dust on the change in the size and weight of the samples was studied under laboratory conditions. It is shown that with an increase in the amount of the zinc component in the composition of the saturating mixture in the form of zinc powder (Znst) or hot‑dip galvanizing waste‑zinc dust (Znotx), the thickness of the galvanized product also increases. The obtained graphic dependences of the growth of the thickness of the samples on the amount of zinc components have the same pattern of change. It is also shown that with an increase in the zinc component in the composition of the saturating mixture in the form of zinc powder (Znst) or hot‑dip galvanizing waste – zinc dust (Znotx), the mass of the galvanized product also increases. The graphic dependences of the growth of their mass on the amount of different zinc components also have the same character of change.It has been established that the most intensive character of the growth in the values of the size and mass of the product is observed when the content of the zinc‑containing component in the mixture is more than 60 % for both saturating media, whether in the Znst‑Al2O3 or Znout‑Al2O3 medium. At the same time, products galvanized in a saturating Znst‑Al2O3 medium have large dimensions and masses. |
