First, a visual inspection. The surface of the galvanized wire should have no obvious defects, such as obvious creases, cuts, scratches, etc. At the same time, the uniformity and consistency of the coating should be checked. The surface of the electrogalvanized wire with uniform and consistent coating should show uniform silver-white color, and there is no obvious oxidation phenomenon.
Secondly, size detection is carried out. The size of galvanized wire includes two aspects: diameter and length. Diameter is an important size parameter of electrogalvanized wire, which should meet the requirements of relevant national standards. The length also needs to be checked according to the actual requirements to ensure that it meets the requirements.
Thirdly, the thickness of the coating is measured. The thickness of electroplated layer is one of the important indexes to evaluate the quality of electrogalvanized wire. The commonly used measurement methods are magnetic induction method, coating thickness gauge and so on. According to the requirements of use, the thickness of the coating should meet certain requirements.
In addition, tensile strength testing is also required. Tensile strength is one of the important indexes to evaluate the quality of metal products. It can be tested by tensile test and other methods to ensure that the strength of electrogalvanized wire meets the requirements during use.
In addition, it is also necessary to consider the corrosion resistance of electrogalvanized wire. In applications, galvanized wire is often subjected to environmental effects such as oxidation and corrosion, so its corrosion resistance is very important. It can be tested by soaking test, salt spray test and other methods to ensure that the electrogalvanized wire has good corrosion resistance.
After that, it is also necessary to consider the functional performance of the electrogalvanized wire. According to different application requirements, some special functional performance tests can be carried out, such as electrical conductivity, flexibility, etc.
In summary, the evaluation of the quality of electrogalvanized wire needs to consider the appearance, size, plating thickness, tensile strength, corrosion resistance and functional properties. Through the detection and testing of the system, the quality of electric galvanized wire can be evaluated in many aspects and ensure that it meets the requirements of use. At the same time, it is necessary to follow the relevant national standards and specifications to improve the reliability and stability of the quality of electrogalvanized wire.
