Brief Description
Description : | 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 |
