选矿厂用聚丙烯酰胺
Mineral processing plant
选矿废水具有水量大，悬浮物含量高，含有害物质种类较多的特点。其有害物质是重金属离子和选矿药剂。重金属离子有铜、锌、铅、镍、钡、镉以及砷和稀有元素等。
在绝大多数的矿物加工过程中，需要应用高分子量或超高分子量的絮凝剂进行沉降和离心。聚丙烯酰胺可以提供这种高分子或超高分子量絮凝剂，保证沉降和离心过程的效果好、效益佳。
选矿厂专用聚丙烯酰胺系列产品是高聚合度合成的水溶性线型高分子聚合物。完全溶于水中，并由于它的微颗形式，能快速溶解。不同类型的聚丙烯酰胺具有不同的活性基团，能使不同的悬浮粒子絮凝，便于过滤，分离。该系列产品几乎不溶于任何有机溶剂，大量溶于水。在许多行业中被广泛应用于絮凝、增稠、粘结、阻垢、稳定胶体、减阻、成膜、凝胶及生物材料等。该产品特点 粘度大 ，能有效处理选矿厂污水。 Mineral processing plant wastewater has the characteristics of large amount of water, high content of suspended matter and many kinds of harmful substances. Its harmful substances are heavy metal ions and mineral processing agents. Heavy metal ions include copper, zinc, lead, nickel, barium, cadmium, arsenic and rare elements.
 
In most mineral processing processes, flocculants with high molecular weight or ultra-high molecular weight are needed for sedimentation and centrifugation. Polyacrylamide can provide this kind of macromolecule or ultra-high molecular weight flocculant, which can ensure the good effect and benefit of sedimentation and centrifugation process.
 
Polyacrylamide series products specially used in concentrators are water-soluble linear polymer with high degree of polymerization. It is completely soluble in water and can dissolve rapidly due to its micro-particle form. Different types of polyacrylamide have different active groups, which can flocculate different suspended particles, facilitate filtration and separation. This series of products are almost insoluble in any organic solvent and soluble in water in large quantities. In many industries, it is widely used in flocculation, thickening, bonding, scale inhibition, stabilizing colloids, drag reducing, film forming, gel and biological materials. The product features high viscosity and can effectively treat wastewater from concentrator.
