Because of the powder, it is easy to fly around when dissolved, polluting the working environment. How to dissolve polyacrylamide powder, this dissolution method is very important to us. The dissolution tank is mainly cylindrical, and the liquid level in the cylinder is about 1.2 to 1.5 times the diameter of the cylinder, which is the ideal liquid level.
The corner of the square cylinder is easy to form dead corners due to the stray flow effect. In order to avoid the accumulation of dead corners of undissolved particles, it should be avoided as far as possible. The mixer can be vertical or horizontal. If the polyacrylamide flocculant powder is exposed to the air for more than one year, the quality will not change, but because the product has strong moisture absorption, please seal it again and store it, and it can be used first.
The storage time of liquid products is short, usually liquid polyacrylamide flocculant is 6 months, latex polyacrylamide flocculant is generally 3 to 6 months, slightly stirred before use, 1% polyacrylamide flocculant solution should not be stored for more than 1 month. Polyacrylamide flocculants should be stored in a low temperature, ventilated, dry, cool place. Glue and latex products in the loading and unloading, transportation process, try to avoid polyacrylamide flocculant and iron, copper and other metals contact, transport pump should choose diaphragm pump and piston pump. Mixing is the key to the reaction. It’s a very important part. The coagulant hydrolysate should be rapidly diffused to every detail of the water in this process, so that all colloidal particles almost come out and condense at the same time, so the flocculation effect is good. Due to the simultaneous destabilization and agglomeration of colloidal particles in the mixing process, this process can be called primary coagulation.
However, the main role of the process is mixing, so it is usually called the mixing process. The essence of the coagulation process is the diffusion of coagulant hydrolysate in water. At the same time, the stability of the colloidal particles in water to produce clots is the premise to achieve good flocculation effect, but also the key to save the drug administration, different properties of polyacrylamide have different treatment methods.
