【摘要】：利用納米二氧化硅固定化脂肪酶對環(huán)氧樹脂進行改性�？疾焱繉又兄久富钚宰兓�、改性前后環(huán)氧涂層的物理性能變化,以及改性涂層對A3碳鋼在循環(huán)水中的緩蝕性能影響。結果表明,添加2%質(zhì)量分數(shù)固定化脂肪酶時,涂層中的脂肪酶活性能夠達到2300U/g,涂層硬度為2 H,附著力為3級,用電化學法測得的涂層阻抗值最大,且顯著高于未添加固定化脂肪酶的環(huán)氧涂層,說明添加固定化脂肪酶后環(huán)氧涂層的耐腐蝕性能得到提高。
[Abstract]:The modified epoxy resin was modified by immobilized lipase with nano-silica. The changes of lipase activity in the coating and the physical properties of the epoxy coating before and after modification were investigated. And the effect of modified coating on corrosion inhibition of A3 carbon steel in circulating water. The results show that the lipase activity in the coating can reach 2 300 U / g, the hardness of coating is 2 H, and the adhesion is 3 grade when 2% mass fraction is added to immobilize lipase. The impedance of the coating measured by electrochemical method was the highest and significantly higher than that of the epoxy coating without immobilized lipase, which indicated that the corrosion resistance of the epoxy coating was improved after the immobilized lipase was added.
