Abstract:

Phytic acid,a natural nontoxic chemical,is a kind of organic phosphate compound extracted from foodstuff.Corrosion and scale inhibitions of phytic acid are evaluated by rotary coupon test and aeration method,respectively.The experimental result shows that phytic acid has certain corrosion and scale inhibition.Its scale inhibition is inferior to PBTCA,HEDP and HPMA,but has good synergistic effect when prepared with other corrosion and scale inhibitors.

Key words: phyticacid, corrosioninhibitor, scaleinhibitor, watertreatmentagent, compositechemicals

摘要：

植酸是从粮食作物中提取的有机磷酸化合物，它是天然的无毒化工产品。通过鼓泡法和旋转腐蚀挂片失重法对其阻垢性能和缓蚀性能进行了评价。结果表明植酸具有一定的缓蚀性能和阻垢性能，其阻垢性能虽比常用的药剂PBTCA、HEDP、HPMA稍差，但可通过同其他的药剂复配生成低磷或无磷的阻垢剂，是较有发展前景的绿色缓蚀阻垢产品。
