Spray Galvanizing is a widely used surface coating technique to prevent corrosion of multiple materials. The most common application of this media is the use of zinc to protect iron substrates. Thermal spray coating offers excellent corrosion protection in moist conditions.
The spray galvanizing techniques at Mythri adhere to national and international standards applied as a corrosion protection restoration to damaged sections of galvanized, welded steel.
There is zero risk of heat distortion or weld damage of the surface.
The spray galvanizing media can support surfaces of any shape and volume.
The spray galvanizing process is highly cost effective and economical.
The properties of the thermal spray coating can be controlled.
The coating can act as a base and offer long life structures.
The zinc Application forms a protective layer against corrosion.
The surface of the metal is prepared by abrasive blasting with thorough cleaning and roughening.
Zinc wire at a controlled rate is applied into an arc spraying process and the atomised metal impinges the coated surface.
Zinc deposited follows a process through spraying in contrast to the conventional methods of galvanizing.
Test for Thickness
At Mythri, ensuring that the coating meets the accepted national and international standards. A self calibrated coating thickness gauge with samples are tested for thickness of Zinc as per IS:3202:1982.
Test for Bond
At Mythri, Mechanical bonding of zinc coating to the substrate is tested using an imported bond tester as per ASTM-D 4541-1985. A dolly is fixed on the sample using adhesives to indicate the bonding strength in PSI
Test for Precision
At Mythri, the sample is subjected to multiple levels of dipping in copper sulphate Solution ideally 4 times for a duration of one minute each and checked for coloration indicating non uniform coating at the 4th level.
Test for Purity
At Mythri, the purity of zinc is tested at an external lab ensuring 99.95% as per the IS:209 standards along with the certification. The purity test certificates of zinc are available to the clients on demand.
Mythri supports maximisation of timely deliverables to real-time schemas with well planned and executed solutions without conventional lags.
