選礦廠用聚丙烯酰胺
Mineral processing plant
選礦廢水具有水量大，懸浮物含量高，含有害物質種類較多的特點。其有害物質是重金屬離子和選礦藥劑。重金屬離子有銅、鋅、鉛、鎳、鋇、鎘以及砷和稀有元素等。
在絕大多數的礦物加工過程中，需要應用高分子量或超高分子量的絮凝劑進行沉降和離心。聚丙烯酰胺可以提供這種高分子或超高分子量絮凝劑，保證沉降和離心過程的效果好、效益佳。
選礦廠專用聚丙烯酰胺系列產品是高聚合度合成的水溶性線型高分子聚合物。完全溶于水中，并由于它的微顆形式，能快速溶解。不同類型的聚丙烯酰胺具有不同的活性基團，能使不同的懸浮粒子絮凝，便于過濾，分離。該系列產品幾乎不溶于任何有機溶劑，大量溶于水。在許多行業中被廣泛應用于絮凝、增稠、粘結、阻垢、穩定膠體、減阻、成膜、凝膠及生物材料等。該產品特點 粘度大 ，能有效處理選礦廠污水。 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.
