Are the particles in polyaluminum chloride water insoluble?

Are the particles in polyaluminum chloride water insoluble? When purchasing polyaluminum chloride, it is often found that there are some granular impurities in polyaluminum chloride products. These are actually just some agglomerations of polyaluminum chloride and will not affect the use effect of polyaluminum chloride.

One of the production processes of polyaluminum chloride is the drum drying type. The polyaluminum chloride produced by this process contains more particles. So how do these impurities come from? When the polyaluminum chloride is dried by the drum, there will often be uneven rolling and pushing. In this state, these small particles will appear after the polyaluminum chloride is dried. This is just unsightly. In use, it will dissolve after adding water, and the effect will not be affected. The effect is that it may dissolve more slowly than the powdered polyaluminum chloride.

The water-insoluble substance of polyaluminum chloride refers to the presence of water in the aqueous solution after dissolution. For example, some polyaluminum chloride may find the aqueous solution to be turbid after dissolution, which is caused by the water-insoluble substance. This is different from the particulate matter in polyaluminum chloride products. The more water-insoluble polyaluminum chloride is dissolved, the more turbid the aqueous solution is. Similarly, the less water-insoluble polyaluminum chloride is dissolved, the aqueous solution will appear more transparent. This is also the current way to judge that polyaluminum chloride is insoluble in water. one. The water-insoluble substance of polyaluminum chloride is slow and gradually blocks the pipeline during the use process. Therefore, the water-insoluble substance of polyaluminum chloride has a strict index.

The current method to reduce the water insolubleness of polyaluminum chloride is through plate and frame filter press. At this time, the particulate matter in the polyaluminum chloride product is much less, and the content of water insoluble matter will be greatly reduced.
