建筑物包括房屋、堤坝、桥梁、塔、碑长期暴露在自然环境中,经受空气、雨水、酸雾的侵袭,构成建筑的硅酸盐材料遭受腐蚀、损坏、对建筑物的寿命带来很大影响。对建筑物的修复和保护是一项很重要的技术,由于有机硅化合物可以在建筑物的硅酸盐材料表面形成性能优异的憎水膜,成为建筑材料的保护剂,特别是对于混凝土建筑其保护功效更是十分明显。1 有机硅对混凝土的保护机理一般硅酸盐建筑材料如混凝土、砂浆混凝土、加气混凝土、陶瓷、砖、瓦等都是多孔性亲水性材料。对于硅
Buildings, including houses, dams, bridges, towers and steles, have been exposed to the natural environment for a long period of time. They are exposed to the invasion of air, rain and acid mist. The silicate materials that make up the building are subject to corrosion and damage, which greatly affects the life of a building influences. Building repair and protection is a very important technology, because the organic silicon compounds in the building silicate material surface properties of hydrophobic film, become a protective agent for building materials, especially for the construction of concrete Protection is more obvious. 1 silicone protective mechanism of concrete General silicate building materials such as concrete, mortar concrete, aerated concrete, ceramics, bricks, tiles and other porous hydrophilic materials. For silicon
