How to judge the quality of hot-dip galvanized standard parts? Because of the emergence of the machine, so there must be parts, it also appears people's concern about the service life of parts, so how to make the service life of parts longer, this has become a problem that people need to consider and solve.
     People are trying to solve this problem in various ways, so hot-dip galvanizing is a representative attempt. So not all hot dip galvanizing is OK, there are special regulations about this country, then only qualified, or good quality can circulate in the market, then how to judge the good and bad quality of hot dip galvanizing!
     On the quality of hot dip galvanizing, this can be judged from two aspects. First of all, judging from the appearance, the first thing you have to look at is whether there is a complete galvanized layer on the appearance of the hot dip galvanizing, if there are black spots, bubbles and other problems, the galvanizing is a phenomenon of leakage plating, which means that the quality of the hot dip galvanizing is not good. In addition to the previous, there is to see whether the combination of the hot-plated zinc layer and the matrix is firm enough, to observe whether there is peeling, and falling off and other phenomena, if there is, this can also be said to be a poor quality product. Another thing to observe is whether the appearance of hot dip galvanized solid is smooth without caking and sliding. In addition to observing the appearance of hot dip galvanizing, instruments can also be used to detect, because the thickness of the zinc layer can be tested with a thickness gauge, and the quality of the hot dip galvanizing can also be analyzed according to the chemical analysis of antimony chloride.
