-
摘要: 以丙烯酰胺为单体,通过分散聚合法制备了一种聚丙烯酰胺微球降滤失剂,并与水溶液聚合法、反相乳液聚合法分别合成的聚丙烯酰胺降滤失剂进行了对比。通过优化引发剂加量等方法,合成了可溶解的聚丙烯酰胺微球降滤失剂FA-25。该方法合成过程无毒、环保,无需进行后处理。通过透射电镜分析、热重分析、粒径分析、凝胶色谱法分子量分析等手段,对FA-25进行了结构表征研究,结果表明FA-25为球形,尺寸在40~200 nm范围内,分子量可以达到104 928,初始热分解温度200 ℃。在膨润土浆中加入1% FA-25后能够将中压滤失量降至13.8 mL,优于水溶液合成的产品及反相乳液法制备的产品。此外,产品抗温性能良好,可以抵抗200 ℃的高温,具有良好的应用前景。Abstract: A microsphere polyacrylamide (PAM) filter loss reducer FA-25 has been developed with acrylamide monomer through dispersion polymerization. The filtration control performance of FA-25 and other PAMs made through aqueous polymerization and inverse emulsion polymerization was compared. The dispersion polymerization is nontoxic and environmentally friendly, and the product does not need any post-treatment. The product FA-25 was characterized through TEM analysis, TG analysis, particle size analysis and molecular weight analysis through gel chromatography. It was proved that the particles of FA-25 are in a shape of sphere, with particle sizes between 40 nm and 200 nm. The molecular weight of FA-25 is 104,928, and the initial thermal decomposition temperature is 200 ℃. A bentonite slurry treated with 1% FA-25 had its API filtration rate reduced to 13.8 mL, this proves that FA-25 has filtration control performance better than the PAMs made through water solution polymerization and inverse emulsion polymerization. FA-25 functions normally at temperatures up to 200 ℃. Good performance of FA-25 renders it good application prospect.
