Silane impregnation is simply to say that the surface of concrete is sprayed with silane. First, explain what is silane. In general seaport engineering, inland saline alkali land, engineering with severe freeze-thaw damage and bad environment, it is required to carry out the silane impregnation and anti-corrosion construction of concrete structure. In this case, the silane only refers to isobutyl (ene) triethoxysilane db-h538 (liquid) and isooctyl triethoxysilane db-h580 (paste), and the content requirements are relatively high, above 98.9% and 80% respectively Above.
Second, explain what impregnation is. Impregnation is the process of spraying on the surface of concrete structure. According to the different requirements of engineering design documents, different silane products used, and different construction positions, the spraying methods or tools will be different, such as roll coating, high-pressure spraying, airless spraying, etc.
No matter the index requirements for silane products or the application and testing requirements after spraying, they are generally in accordance with the standards of technical code for corrosion protection of concrete structures of Seaport Engineering (jtj275-2000) issued by the Ministry of communications.
