The preparation of qualified refined brine in the soda ash industry requires clarification of the brine. The sedimentation speed and sedimentation effect of impurities play a decisive role in the quality of the brine. Soda plant polyacrylamide (PAM) is an organic macromolecule with polar groups. Not only can the sediment be adsorbed, but also with the help of the molecular chain length of the macromolecules, it is possible to "bridge" between the particles to form flocs with a uniform space network structure, which greatly increases the precipitation speed and significantly improves the settlement effect.
The first production process in the soda ash industry is to prepare qualified refined brine, in which the calcium and magnesium impurity ions in the crude brine are removed to clarify the brine. The clarification effect of the brine plays a decisive role in the product quality of soda ash. In addition to ensuring that an appropriate amount of qualified causticizing solution is added during the clarification process, it is also necessary to ensure that the precipitated molecules in the brine can be quickly and completely precipitated from the saline solution. We generally use the method of adding a settling agent to improve the clarification effect.
The precipitation principle of solid-liquid separation of crude brine except calcium and magnesium in the clarification tank is: sedimentation depends on the action of a certain force, with the help of the density difference of solid particles and fluid (liquid or gas), so that they reach the separation process. This force can be gravity or centrifugal force. Therefore, the settlement process is divided into gravity settlement and centrifugal settlement. The solid sedimentation process of the clarification barrel used in the production of brine workshop is the gravity sedimentation process.
The clarification process of refined brine in the soda ash industry uses Shouxin brand anionic polyacrylamide as a settling agent, and its settling effect is obvious. The principle of sedimentation aid is that Soda plant polyacrylamide (PAM) is an organic macromolecule with polar groups. It can not only adsorb precipitates but also can form a "bridge" between the particles by virtue of the molecular chain length of the macromolecule. The flocs with a uniform space network structure have no effect on the compression of precipitation, but greatly increase the precipitation speed. The scientific use of polyacrylamide PAM in the soda industry not only reduces waste, saves costs, but also makes a great contribution to protecting the environment.
