高效低膦复合型缓蚀阻垢剂的研制

The Preparation of Composite Corrosion and Scale Inhibitor with High Efficient and Low Phosphoric

以有机膦酸盐、有机膦羧酸盐、表面活性剂、锌盐为主要原料,复配出一种全有机多元复合型缓蚀阻垢剂。以某石化公司的循环冷却补充水为介质,通过旋转挂片腐蚀法和碳酸钙沉淀法测定其缓蚀率和阻垢率,优选出六种复合型缓蚀阻垢剂配方,并将其与市售缓蚀阻垢剂进行对比。结果表明,这六种配方的缓蚀阻垢剂的缓蚀率均为95%以上,对碳酸钙的阻垢率也均达到95%以上,缓蚀、阻垢性能均优于市售商品,且具有高效、环保的特点。

Taking organic phosphonic acid, organic phosphono carboxylic acid, surfactant, and sale with zinc as main material, a new organic muhicomposite scale and corrosion inhibitor was complexed. Petrochemical company after the circulating cooling water in the depth of treatment as the media, the corrosion inhibition rate and scale inhibition rate were determined by rotation coupon corrosion and calcium carbonate precipitation methods, then six kinds of composice scale and corrosion inhibiton formnala were choisen. The comparison results to merchant products show that the corrosion inhibiton rate and scale inhibition rale of six corrosion and scale inhinbitors are more than 95%, and scale inhibition rale for calcium carbonale is 95% or more. The corrosion inhibition and scale inhibition performances of the high efficent and environmental protection inhibition are more excellent than that of merchant products.
