  • The precautions of galvanizing wire in galvanizing are introduced in detail! When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire.

  • Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by the customer, ensure that the metal wire can achieve the role of rust and corrosion prevention, and meet the service life required by the customer. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound with an inward end to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test. This item is determined according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.

  • When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.

  • Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives should be used to obtain a coating that meets the requirements of this standard. Light treatment should be carried out after light plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied for activation for 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
