As high purity polyacrylamide is powdered, it is easy to fly around when dissolved and pollute the working environment. How to dissolve high purity polyacrylamide powder is very important to us. The dissolution tank is mainly cylindrical, and the height of the liquid level of the cylinder is about 1.2~1.5 times of the diameter of the cylinder, which is the ideal liquid level.
Because of the flow effect, the four corners of the square cylinder are easy to produce dead corners. In order to avoid the accumulation of insoluble particles stagnant dead Angle, should try to avoid selection. The blender can be vertical or horizontal. If pam polyacrylamide powder products are not opened and exposed to air, the quality of more than a year will not change, but because of the strong hygroscopic property of the product, must be sealed and preserved, can be used first.
At the same time, it also expanded many important downstream products, widely used in oil, paper, water treatment, textile and other industrial fields. High purity polyacrylamide is a linear water-soluble polymer polymer that is copolymerized or copolymerized with other monomers and has a mass fraction of more than 50%. Mainly from its molecular structure characteristics and special physical and chemical properties.
The reason why metal mine wastewater is not easy to precipitate: gold mine wastewater is generally difficult to naturally precipitate, the main reason is that gold mine wastewater is a coarse dispersion, the sediment particle size is different, the dispersion medium is water. The clay water-inert limb consists of a marginal adsorption layer and a diffusion layer. Because a large number of anions are adsorbed on the edge surface of micelles, the charge between micelles is equal and it is difficult to precipitate. Metallic mineral wastewater is difficult to precipitate naturally. It can adsorb suspended solid particles and form large flocculation between particle bridge or through charge and particle.
