YJ-R505 is a mixed type (DCI) composite amino alcohols of organic inhibitor, by alcohol amine to many different types of inorganic group has certain rust of compound and into, does not contain nitrite. Join YJ-R505 to concrete, different groups of inhibitors of membrane, membrane can adsorb and oxide film formed on the steel surface, to blockade the harmful substances and steel surface contact, prevent or delay the corrosion occurred; at the same time, YJ-R505 has the effect of reducing the water, can effectively improve the performance of concrete mixture and impermeability of concrete increases, reduce the diffusion rate of dissolved oxygen and diffusion coefficient of chloride ions. The comprehensive function of the two, and finally improve the durability of the concrete structure, extend the service life of concrete structure to.
