Hex Nut Factory introduced how to judge the quality of hot-dip galvanized standard parts? Because of the emergence of machines, there must be parts, and then people are concerned about the service life of parts, so how can the service life of parts be improved? Long, this has become a problem that people need to consider and solve.

People are trying various methods to solve this problem, so hot-dip galvanizing is a representative result of attempts. Then not all hot-dip galvanizing is possible. There are still special regulations in this country. In this case, only qualified, or good quality, can be circulated in the market, so how to judge hot-dip galvanizing The quality is good and bad!

Regarding the quality of hot-dip galvanizing, this can be judged from two aspects. First of all to judge from the appearance, the first thing you need to see is whether there is a complete galvanized layer on the appearance of the hot-dip galvanizing. If there are problems such as black spots, bubbles, etc., the galvanizing is a phenomenon of missing plating. It also shows that the quality of this hot-dip galvanizing is not good. In addition to what has been said before, it is necessary to check whether the hot-dip galvanized layer and the substrate are firmly bonded, and to observe whether there is peeling, peeling, etc., if any, this can also be done. Said it is a poor quality product. Another thing to observe is whether the appearance of the hot-dip galvanized fasteners is smooth and free from agglomeration or slippage. In addition to observing the appearance of hot-dip galvanizing, you can also use the instrument to test, 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 antimony chloride chemical analysis method. .

Through the above introduction, China 2H Hex Nut Factory hopes that you can simply refer to the content of this article in future use.
