Chemical treatment of steel rebar to prevent rust formation during storage and transport.
The chemical treatment can be done offline or online in a rebar production line
. The treatment process involves contacting the rebar surface with the treatment solution for a duration of 1-2 seconds by spraying or dipping.
The chemical treatment can be done at ambient conditions or at elevated temperatures of up to 600 ° The chemical treatment results in the formation of an invisible conversion coating of less than 1 m on the rebar surface.
The chemical treatment process does not impact the bond strength of rebar with concrete.
The process is scalable and economical
Benefits
