Cold galvanized wire is a commonly used metal material, which has the advantages of anti-corrosion, anti-wear, etc., and is widely used in construction, furniture, automobile and other industries. In order to ensure the quality of cold galvanized wire, strict quality testing is required. The following are some methods and steps for testing the quality of cold galvanized wire:
1. Appearance inspection: First of all, the appearance of cold galvanized wire is inspected to check whether the surface is smooth, whether there is oxidation, rust and other phenomena, whether there are obvious defects and damage.
2. Size detection: Use ruler and other tools to measure the diameter and length of cold galvanized wire to ensure that it meets the requirements of production standards.
3. Coating thickness detection: Use electroplating coating thickness gauge and other equipment to detect the coating thickness of cold galvanized wire to ensure that the design requirements are met.
4. Tensile strength test: tensile test to detect the tensile strength of cold galvanized wire to ensure compliance with relevant standards.
5. Bending test: The bending test of cold galvanized wire is carried out to detect its performance in the bending process, such as whether there are cracks, deformation and other phenomena.
6. Salt spray test: Put the cold galvanized wire into the salt spray test chamber for salt spray corrosion test to observe whether there is corrosion and other phenomena.
7. Packaging inspection: Then check the packaging of cold galvanized wire to ensure that the package is intact and will not be damaged during transportation.
