【摘要】：水利水電行業(yè)中,由于受到含沙水流的沖磨、氣蝕破壞,水電站泄水建筑物的表面存在不同程度的磨損,因此對大壩混凝土表面進行修補越來越受到行業(yè)內的重視。本研究通過對傳統(tǒng)的環(huán)氧樹脂抗沖磨修補材料進行增韌改性,研制出一種韌性高、放熱少、高強度、抗沖磨性能好的環(huán)氧樹脂抗沖磨材料,并與傳統(tǒng)環(huán)氧樹脂進行力學性能和抗沖磨性能作比較。同時介紹了環(huán)氧樹脂的施工工藝,以滿足實際工程的需要。
[Abstract]:In the water conservancy and hydropower industry, due to erosion and erosion by sand water flow, the surface of the drainage structure of hydropower station is worn out to varying degrees, so more and more attention has been paid to repairing the concrete surface of the dam. By toughening and modifying the traditional epoxy resin, a kind of epoxy resin with high toughness, less exothermic heat, high strength and good impact wear resistance was developed. The mechanical properties and abrasion resistance of epoxy resin were compared with those of traditional epoxy resin. At the same time, the construction technology of epoxy resin is introduced to meet the needs of practical engineering.
