Arginine‐modified polyepoxysuccinic acid (Arg‐PESA) was used as a scale inhibitor to study its anti‐scaling and anti‐corrosion performance. The existence of arginine groups enhances the adsorption and chelation of calcium substances, thus inhibiting the formation of a calcium scale. The effects of temperature, scale inhibitor concentration, pH, and calcium ion concentration on scale inhibition performance were studied. The morphologies and structures of the calcium scale and carbon steel coupons were observed and characterized by spectroscopic and microscopic methods. The interaction between Arg‐PESA and different crystal surfaces of calcium carbonate was simulated by molecular dynamics to elucidate the anti‐scaling mechanism. The addition of Arg‐PESA also significantly enhanced the dispersion of iron oxide.

精氨酸修饰的聚环氧琥珀酸作为防垢防腐蚀剂的评估

精氨酸改性的聚环氧琥珀酸（Arg-PESA）被用作阻垢剂，以研究其防垢和防腐性能。精氨酸基团的存在增强了钙物质的吸附和螯合，从而抑制了钙垢的形成。研究了温度，阻垢剂浓度，pH和钙离子浓度对阻垢性能的影响。通过光谱和显微镜方法观察并表征了钙垢和碳钢试样的形态和结构。通过分子动力学模拟了Arg-PESA与碳酸钙不同晶体表面之间的相互作用，以阐明其防垢机理。Arg-PESA的加入也显着增强了氧化铁的分散性。
