引用本文摘 要：單獨使用環氧樹脂或緩蝕劑對鋼筋混凝土結構中鋼筋的防護效果有限。為取得更好的防護效果，本文嘗試將緩蝕劑和環氧樹脂組合使用，采用半電池電位法測定緩蝕劑和環氧樹脂不同涂刷順序對混凝土構件中鋼筋的防護效果。試驗結果表明，先涂一層緩蝕劑再覆蓋一層環氧樹脂對混凝土構件中的鋼筋防護效果最佳，能有效降低鋼筋的腐蝕電位，使構件中鋼筋的腐蝕概率小于5%，因此，緩蝕劑與環氧樹脂的組合使用能有效保護鋼筋不被腐蝕。 Abstract: The protection cannot show the intact effectiveness when epoxy resin or corrosion inhibitors is used alone on the reinforced steel concrete structure. In this paper, making a combination of epoxy resin and corrosion inhibitors is tried for getting a better protective effect, and half-cell potential method is used to determine the protective effect of epoxy and corrosion for reinforced concrete structure when they are applied in different order. The results show that brushing a layer of corrosion inhibitor then covering a layer of epoxy corrosion inhibitor has a better protection on reinforced steel concrete structure, which can effectively reduce the potential corrosion of the steel and makes the probability of corrosion of steel members less than 5%. Therefore, using the combination of corrosion inhibitor and epoxy resin can effectively protect steel from corrosion.
