Anti-corrosion method for outer wall of overground building
The invention provides a corrosion prevention method for an overground building outer wall, and relates to the technical field of wall corrosion prevention. The anti-corrosion method for the outer wall of the overground building comprises the following steps that the surface of the outer wall of the overground building is coated with magnesium cementing material mortar, and a magnesium cementing material mortar layer is formed on the surface of the outer wall of the overground building; the magnesium cementing material mortar is prepared from the following raw materials: active magnesium oxide powder, a magnesium salt solution, sand, fibers and a modifier, the mass ratio of the active magnesium oxide powder to the magnesium salt solution to the sand to the fiber to the modifier is 1: (1.5-5): (1-3): (0.01-0.1): (0.05-0.1); the modifier is fly ash and phosphoric acid, or fly ash, ferric sulfate and nano-zinc oxide; the mass fraction of the magnesium salt solution is 20-40%. The magnesium cementing material mortar is used as an anticorrosive coating on the surface of the outer wall of the building, and the coating has a salt-resistant property and can prevent erosion of salt-containing sand storm or salt dust storm.
本发明提供了一种地上建筑物外墙防腐方法，涉及墙体防腐技术领域。本发明提供的地上建筑物外墙防腐方法，包括以下步骤：将镁质胶凝材料砂浆涂覆至地上建筑物外墙表面，在所述地上建筑物外墙表面形成镁质胶凝材料砂浆层；所述镁质胶凝材料砂浆的制备原料包括活性氧化镁粉、镁盐溶液、砂子、纤维和改性剂；所述活性氧化镁粉、镁盐溶液、砂子、纤维和改性剂的质量比为1：1.5～5：1～3：0.01～0.1：0.05～0.1；所述改性剂为粉煤灰和磷酸，或者粉煤灰、硫酸铁和纳米氧化锌；所述镁盐溶液的质量分数为20～40％。本发明采用镁质胶凝材料砂浆作为建筑物外墙表面的防腐涂层，该涂层具有耐盐属性，防止含盐风沙或盐尘暴的侵蚀。
