改性聚丙烯酰胺对方解石的助滤性能
Study on Filterability of Polyacrylamide and Modified Polyacrylamide to Calcite
【摘要】 研究了聚丙烯酰胺 ( PAM)、羟甲基化聚丙烯酰胺 ( HMPAM)、磺甲基化聚丙烯酰胺 ( SMPAM)和氨甲基化聚丙烯酰胺 ( AMPAM)对细粒方解石的助滤性能。结果表明 :在相同的相对分子质量下 ,改性 PAM对细粒方解石的助滤效果为 :SMPAM>HMPAM>PAM>AMPAM。
【Abstract】 In order to improve the filtration efficiency and reduce water content in the filter cake, polyacrylamide was modified with a number of chemicals and then they were used as filters of particle calcite slurry. The experimental results showed that the filterability as resulted was sulfomethyl polyacrylamide>polyacrylamide > hydroxymethyl polyacrylamide > aminomethyl polyacrylamide.
