摘要: 成功地制备了一种能在水中定量溶解的磷酸盐玻璃阻垢剂.在30℃时,其阻垢率达90%.利用比色法测量出与阻垢效率有直接关系的正磷酸根离子(简称正磷)和聚磷酸根离子(简称聚磷)浓度,并据此对磷酸盐玻璃阻垢剂的阻垢性能和控释机理进行了研究,探讨了阻垢剂在溶解过程中发生的水解和水化反应.

Abstract: A controlled-release phosphate glass scale inhibitor was prepared successfully, and its rate of scale inhibition reached 90% at 30℃. The concentration of orthophosphate and polyphosphate ions was very important for determining the rate of scale inhibition, some properties of the glass acted as a scale inhibitor were also discussed. The results show that the dissolution mechanism of the glass in water is controlled by hydrolysis and hydration reaction.

Key words: phosphate glass, controlled release, scale inhibitor
