Polymeric aluminum ferric chloride (PAFC) is an inorganic polymer compound, which is widely used in the field of chemical production raw materials. It has unique properties and uses that make it a key component in many chemical processes. This article will detail the properties and uses of polymeric aluminum ferric chloride.

1. Polymeric aluminum ferric chloride properties

1. Physical properties: Polymeric aluminum ferric chloride usually presents a yellow or light yellow powder or granular, with strong hygroscopicity.
2. Chemical properties: Polymeric aluminum ferric chloride is easy to dissolve in water, releasing a large number of positive charge ions, which can effectively neutralize the negative charge ions in water, so as to realize the purification of water. In addition, polyaluminum ferric chloride also has good thermal stability and acid-base stability.

2. the use of polymeric aluminum ferric chloride

1. water treatment agent: polymeric aluminum ferric chloride as a highly efficient inorganic flocculant, widely used in the field of water treatment. It can effectively remove the suspended solids, colloids, pigments and organic pollutants in the water, reduce the turbidity of the water, and improve the water quality.
2. Papermaking additives: In the papermaking process, polyaluminum ferric chloride can be used as a sizing agent and reinforcing agent to improve the tensile strength and tear strength of the paper and improve the printing performance of the paper.
3. Printing and dyeing auxiliaries: Polymeric aluminum ferric chloride can be used for dye fixation in the printing and dyeing industry to improve the adsorption performance and color vividness of dyes.
4. Ceramic additives: In the ceramic production process, polyaluminum ferric chloride can be used as additives to improve the strength and wear resistance of ceramics.
5. pharmaceutical intermediates: polymeric aluminum ferric chloride can be used as intermediates of some pharmaceutical products, participate in the synthesis process, improve product purity and yield.
Precautions for
3.

When using polymeric aluminum ferric chloride, it is necessary to adjust its dosage and pH value according to the specific application scenario and water quality to achieve the best treatment effect. In addition, polymeric aluminum ferric chloride should be stored in a dry, cool place, avoid direct sunlight and high temperature environment.

In short, polymeric aluminum ferric chloride as an important raw material for the production of chemical products, has a wide range of uses and unique properties. In the future chemical production, with the continuous progress of technology and the expansion of application fields, polyaluminum ferric chloride is expected to play a greater role and make greater contributions to the development of the chemical industry.
