Dwell corrosion process features mesh fence

Grid spacing and welded mesh fence all the parameters achieved by computer automation control, welding galvanized wire diameter of 3.5mm-5.9mm, the smallest grid spacing to reach 75 * 12.5mm, maximum grid spacing of 200 * 65mm, so fence has a good protective properties . Also has excellent welding performance , stronger security .
Fence mesh material used high-quality galvanized steel wire , in the case of surface coating damaged fence
Since the protective effect of zinc layer can effectively protect steel from corrosion and prolong the life of the fence .
Spraying production line
With the domestic first-class level is spray production line , spray molding pre-processing to automate the entire operation , and operating conditions and operating parameters for all devices to be monitored by a central control system.
Surface treatment of the main features:
Phosphide
In addition to the product after degreasing phosphating treatment as the underlying pre- spray . After treatment , the surface to form a layer of phosphate chemical conversion coating, surface coating greatly improves the adhesion and corrosion resistance has the ability to improve the adhesion by phosphide can make 2-3 times the corrosion resistance increased by 1 - 2 times.
Passivation
Workpiece phosphate by passivation, phosphate coating pores closed by heavy metal ions , can increase the corrosion resistance of phosphate coatings for more than 10 %.
Powder coating
Excellent film properties : be adjusted according to the kind of liquid paint application and curing conditions for the proportion of polymer solvent , or affect the coating effect is not the case for powder coatings .
Easy to correct bad parts : before the powder polymerization if found defective , just blow off the powder can be re- sprayed . Very convenient.
Film thickness control
Control is more uniform than the conventional liquid paint film thickness , the film thickness need to be able to spray higher .
A wide range of
Colorful decorative and functional powder were used successfully .
Sandblasting
The surface oxide layer is removed by grit blasting to improve the adhesion of the coating .
High-performance anti-corrosion coatings
Higher film thickness
And the substrate has excellent adhesion properties
Dry quickly
High performance polyurethane topcoat
Excellent gloss color stability
Film dense and hard , impact resistance, wear resistance, excellent mechanical properties
Can provide long-term protection and decorative properties
