The protective duration of the galvanized layer of large coil galvanized wire has a great relationship with the thickness of the coating. Generally speaking, in relatively dry main gas and indoor use, the thickness of the galvanized layer is only 6-12μm “, and in harsh environmental conditions, the thickness of the galvanized layer needs to be 20μm “up to 50μm”. Therefore, the environmental impact should be considered when selecting the thickness of galvanized layer.
After passivation treatment, a bright, old and beautiful color passivation film can be formed, which can significantly improve its protective performance. There are many kinds of galvanizing solutions, which can be divided into cyanide plating solution and non-cyanide plating solution according to their properties. Cyanide galvanizing solution has good dispersion and covering ability, smooth and fine coating crystallization, simple operation, wide application range, and has been used in production for a long time.
However, due to the highly toxic cyanide contained in the plating solution, the gas escaping in the plating process is more harmful to the health of workers, and the wastewater must be strictly treated before discharge. Galvanized iron wire has good corrosion resistance and rust resistance, so it can be prevented from being used in some outdoor guardrail or fence, especially on handicrafts, which are also very useful, and the surface of galvanized iron wire is not easy to rust and oxidation.
Now many hardware manufacturers are producing wire, and wire is very easy to rust, if you need to use in the outdoors or wet places, the general customer will require the use of galvanized wire equipment to give the wire a layer of zinc, the thickness can be determined according to user requirements. Galvanized wire equipment is specifically used in the plating of iron, generally speaking, the stability of zinc is much higher than iron, in the daily water vapor or damp places will not rust.
Common galvanized wire equipment is usually used barbecue net, barbecue net is generally required to have a long service life, with galvanized wire equipment to wire a layer of zinc, barbecue net is not easy to be corroded.
