产品特点：两性离子聚丙烯酰胺因分子内含阳离子基和阴离子基，它具备了一般阳离子絮凝剂的使用特点外，表现了更优异的性能。此类絮凝剂可在大范围的PH值内使用，具有更高的滤水量，较底的滤饼含水率，也可用于强酸浸提矿石或从含金属的酸性催化剂中回收有价值的金属。
Characteristics of polyacrylamide
Polyacrylamide purposes
: mainly used as flocculant for suspended particles, coarser, high concentration, particles with positive charge, water PH value is neutral or alkaline wastewater, due to the anionic polyacrylamide molecule chain contains a certain amount of polarity of suspended solid particles can absorb water, make the bridge between particles to form large floc.So it accelerate the
Flocculability: PAM can make the suspended material through electric neutralization, adsorption, flocculation effect.
2. The adhesive properties, can pass the mechanical, physical, chemical, bonding effect.
3. Drag reduction: PAM can effectively reduce the friction resistance of fluid, water with trace PAM can drag reduction of 50-80%.
4. Thickening: PAM under the condition of neutral and acid are thickening effect, when the PH value in more than 10 ℃ PAM easy to hydrolysis.Half the reticular structure, thickening will be more obvious.
两性离子型绝非阴离子型、阳离子型的混合。如果把阳离子聚丙烯酰胺与阴离子聚丙烯酰胺配合使用则会发生反应产生沉淀。所以两性离子产品最为理想。
主要用途：油田调剖堵水剂、与交联剂、 稳定剂、促凝剂联合作用，生成具有重要聚合凝胶和树脂凝胶的高强凝剂胶堵水剂。它通过附、物理堵塞等作用堵塞地层孔隙和裂缝，调整比例，可控制凝胶时间，以适应不同地质清况。各种油污，有机、无机、污水、复杂污水的处理。在PH变化不定的污水系统中，用于污泥脱水，造纸助剂。
注意事项
1、絮团的大小：絮团太小会影响排水的速度，絮团太大会使絮团约束较多水而降低泥饼干度。经过选择聚丙烯酰胺的分子量能够调整絮团的大小。
