Reinforced concrete surface repair method (Sabiran penetration rust prevention method)

By applying Sabiran A to the surface of reinforced concrete, the rust inhibitor (nitrite ions) penetrates and forms a passive film on the rebar, achieving rust prevention treatment!

This technology is a rust prevention method that applies a penetrating rust inhibitor to the surface of reinforced concrete to non-destructively protect the internal rebar from rust. While traditional methods have existed for applying coatings to the surface of reinforced concrete, they have been effective in suppressing the entry of external deterioration factors but have had little effect on already existing deterioration factors (such as chloride ions and areas of carbonation), resulting in insufficient rust prevention effectiveness. In this technology, a newly developed high-penetration rust inhibitor (Sabiran A) is applied to the surface of existing concrete and allowed to penetrate sufficiently into the interior (the surface tension of Sabiran A is 1/2.7 that of conventional products), non-destructively suppressing the latent deterioration of the rebar caused by internal deterioration factors. Furthermore, by applying a water-tightness enhancing agent (Sabiran P), the method simultaneously suppresses further entry of external deterioration factors, thereby providing long-term and stable rust prevention effectiveness for the rebar within the reinforced concrete. ■ Technical Explanation of the Improved Penetration of Sabiran A The rust prevention effect of Sabiran is achieved through the action of a rust inhibitor composition that contains the following composite surfactants: - Specific ether-type nonionic surfactants (maximum surface tension reduction capability) - Water-insoluble specific surfactants (significant wettability enhancement capability)
