以柠檬酸为主要原料合成了丙烯三羧酸丙烯酸共聚物,将此共聚物与聚天冬氨酸和锌盐复配成三元水处理剂,测定了复配物的缓蚀性能、阻垢性能和生物降解性能。结果表明,此三元复合水处理剂缓蚀性能优异,特别适用于高硬度水质,在用量为14mg/L时,对碳钢的缓蚀率达96%以上;28d后生物降解率达到87%,属易生物降解产品。
Propylene tricarboxylic acid acrylic acid copolymer was synthesized by using citric acid as the main raw material. The copolymer and polyaspartic acid and zinc salt were compounded into ternary water treatment agent to determine the corrosion inhibition performance of the compound and scale inhibition Performance and biodegradability. The results show that this ternary compound water treatment agent has excellent corrosion inhibition performance and is especially suitable for high hardness water. When the dosage is 14mg / L, the corrosion inhibition rate of carbon steel reaches more than 96%. After 28 days, the biodegradation rate reaches 87% , Is a biodegradable product.
