【摘要】：通过筛选和优化得到最佳配方的复合型水处理剂,该复合配方的组成为水解聚马来酸16 mg/L+表面活性剂1.5 mg/L+月桂酰基肌氨酸钠75 mg/L+唑类2.0 mg/L。采用静态阻垢法、旋转挂片法和极化曲线法对复合型水处理剂的阻垢缓蚀性能进行了研究,采用扫描电镜对腐蚀试片和垢样的形貌进行了观察。结果表明,复合药剂的阻垢率高达95.70%,对A3碳钢和T2紫铜的缓蚀率分别达到95.58%和93.25%,是一种性能优良的阻垢缓蚀剂。复合药剂通过吸附在CaCO_3晶面的活性生长点,使晶格发生扭曲,以达到阻垢效果,复合药剂对A3碳钢是一种抑制阳极极化为主的混合型缓蚀剂;对T2紫铜是一种抑制阳极极化的阳极型缓蚀剂。
[Abstract]:The compound water treatment agent with the best formulation was obtained by screening and optimizing. The composition of the compound formula is hydrolyzed polymaleic acid 16 mg/L surfactant 1.5 mg/L lauroyl sarcosine sodium 75 mg/L zoles 2.0. Mg / L. Static scale inhibition method. The scale and corrosion inhibition performance of composite water treatment agent was studied by rotating hanging plate method and polarization curve method. The morphology of corrosion test piece and scale sample were observed by scanning electron microscope. The scale inhibition rate of the compound agent was 95.70 and the corrosion inhibition rate of A3 carbon steel and T2 copper reached 95.58% and 93.25% respectively. It is a kind of scale and corrosion inhibitor with excellent performance. The compound agent distorts the lattice by adsorbing the active growth point on the crystal surface of CaCO_3 to achieve the scale inhibition effect. The composite agent is a mixed corrosion inhibitor for A3 carbon steel, which mainly inhibits anodic polarization. For T2 copper, it is an anodic inhibitor to inhibit anodic polarization.
