Polyaluminum chloride spray granulation is a common process method for preparing granular polymeric materials. This article will introduce the principles, application areas and advantages.
Polyaluminum chloride spray granulation utilizes spray drying technology to convert polyaluminum chloride solution into granular matter. Here's how it works::
1.Prepare the solution: dissolve polyaluminum chloride in an appropriate amount of solvent to form a mixed solution.
2.Spray: The mixed solution is sprayed into a stream of hot air in a high-pressure spray.
3.Drying: In a hot gas stream, the solvent quickly evaporates, forming tiny particles.
4.Curing: The particles are cured into a finished product by cooling, etc.
Through the above steps, polyaluminum chloride spray granulation can quickly convert the solution into granular matter, and realize the high-efficiency particle preparation process.
Polyaluminum chloride spray granulation is widely used in the following fields:
1.Sewage treatment agent: Polyaluminum chloride spray granulation can be used to prepare polymer flocculants for sewage treatment. These granular flocculants have a large specific surface area and good flocculation performance, which can effectively remove suspended particles and organic matter in water.
2.Polymer materials: Polyaluminum chloride spray granulation can be used to prepare granular precursors of various polymer materials. These particles can be used as starting substances for polymers, and the required polymer materials can be further prepared by methods such as heat treatment.
3.Pharmaceutical preparations: polyaluminum chloride spray granulation can be used to prepare granular dosage forms of some drugs. The granule dosage form has good solubility and stability, which is convenient for oral or external use, and improves the bioavailability and efficacy of the drug.
Polyaluminum chloride spray granulation has the following advantages over traditional particle preparation methods:
1.High efficiency: Spray drying technology can convert the solution into particles in a short time, which improves the preparation efficiency.
2.Uniformity: Through spray drying technology, the prepared particles have good uniformity and dispersion.
3.Controllability: In the process of polyaluminum chloride spray granulation, the particle size, morphology and other properties of the particles can be controlled by adjusting the spray speed, temperature and other parameters.
4.Wide application: Polyaluminum chloride spray granulation can be applied to various solution systems, and is suitable for particle preparation needs in different fields.
To sum up, polyaluminum chloride spray granulation is an efficient, uniform and controllable particle preparation method, which is widely used in sewage treatment agents, polymer materials and pharmaceutical preparations. Its process principle is simple and clear, and the operation is convenient, which provides an effective solution for particle preparation.
