1，Easy processing: zinc-plated aluminium-magnesium pv bracket, can be cut and used directly;
Traditional hot dip galvanising process: workpiece - degreasing - washing - pickling - washing - immersion in auxiliary plating solution - drying preheating - hot dip galvanising -finishing -cooling -passivation -rinsing -inspection. Poor operation of the former process can cause a number of undesirable reactions in the latter and can significantly increase running costs or result in a poor hot-dip coating of the galvanised product.
If the pre-treatment is poor, the molten zinc will not react sufficiently with the steel and form the desired galvanised film structure. If the post-treatment is poor, the appearance of the galvanised film will be damaged and the commodity value reduced. In contrast to conventional hot-dip galvanised cuts, which require galvanising, paint repair, surface treatment and the repetition of intermediate processes, the direct cutting and use of zinc-aluminium-magnesium coated PV mounts requires no re-processing, is economical to save and is lightweight and aesthetically pleasing.
Therefore, compared with the traditional coating, zinc aluminium magnesium coating reduces a lot of time, manpower, material and financial resources, cost-effective.
2，Automatic repair: Zinc-aluminium-magnesium will automatically repair the coating on the cutting stamping and profiles;
Zinc-aluminium-magnesium coating in the air will have a chemical reaction to form magnesium carbonate, the substance has a buffering effect on the PH value, reducing the dissolution rate of zinc in the anode area and inhibits oxidation. The redox reaction between magnesium ions and oxygen ions creates a protective layer of "white rust" on the photovoltaic support, which is automatically repaired.
Therefore, in the case of damage to the coating cutting, punching, zinc, aluminium and magnesium can react to form a tight magnesium carbonate protective film to repair the damaged parts, thus achieving self-repair of the stent.
3，Corrosion resistance: zinc, aluminium and magnesium corrosion resistance is 5-10 times that of traditional hot-dip galvanising.
Traditional hot-dip galvanised coating with the extension of corrosion time, the area of red rust will increase, while zinc, aluminium and magnesium coatings can get better corrosion resistance, the film "white rust" will form a dense protective layer, for serious deformation caused by the plating of the stent part of the damage has a better protective effect.
