Advisory 13716267347

YJ-R505是一种内掺型（DCI）复合氨基醇类有机阻锈剂，由多种不同类型的醇胺类有机物与具有特定阻锈作用的无机组分复合而成，不含亚硝酸盐。混凝土中加入YJ-R505后，阻锈剂中的不同组分能够在钢筋表面形成吸附膜、沉淀膜以及氧化膜，起到阻断有害物质与钢筋表面的接触，阻止或延缓锈蚀发生的时间；同时YJ-R505具有一定的减水效果，能够有效改善混凝土拌合物的性能以及提高混凝土抗渗性能，降低溶解氧的扩散速率以及氯离子的扩散系数。二者综合作用，最终达到提高混凝土结构的耐久性，延长混凝土结构使用寿命的目的。

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.
