摘要
合成了丙烯酰胺改性三聚氰胺 (蜜胺 )甲醛树脂 ,研究了其絮凝性能。利用烧杯澄清试验法 ,考察了酸碱条件、絮凝剂投加量和静置时间对絮凝性能的影响。实验证明 :酸性条件、絮凝剂投加量为 5 0mg/L、静置时间为2 0min时改性树脂的絮凝效果最好。
Modified melamine formaldehyde resin with acrylamide was synthesized and its flocculability have been studied.By the Jar Test,the effect of acidity, dosage of flocculants and standing time are investigated respectively.Experimental results show that when the pH value is acidic condition, the dosage of flocculants is 50 mg/L and standing time is 20 minutes,the resin exhibits optimum flocculation behavior.Turbidity removal rates of different flocculants are also compared.
