Research on the application and properties of slurry in the field of chemical production

Abstract

slurry as an important chemical production raw material, has a wide range of applications in many fields. In this paper, the nature and use of the slurry will be discussed in detail, in order to provide reference for the scientific application of the slurry. Properties of

1. Slurries

slurries are typically suspensions formed by solid particles dispersed in a liquid. The nature, size, shape and dispersion state of the solid particles have an important influence on the properties of the slurry. The slurry has the following properties:

1. Fluidity: The slurry has a certain fluidity and can flow and fill the container. The fluidity depends on the nature of the solid particles, concentration and liquid viscosity and other factors.
2. Stability: The slurry needs to be stable during storage and transportation to avoid sedimentation of solid particles. Stability is affected by factors such as particle size, density, charge, and liquid viscosity.
3. Uniformity: The solid particles in the slurry should be evenly dispersed to avoid concentration gradients. Uniformity is affected by factors such as stirring speed, time, and particle properties. The use of

2. slurry

slurry has a wide range of uses in the field of chemical production raw materials, and the following main aspects are listed:

1. catalyst carrier: slurry can be used as a catalyst carrier, and the active components of the catalyst are uniformly dispersed in the carrier material to improve the activity and stability of the catalyst.
2. Coating: The slurry can be used as the basic raw material of the coating, and the solid particles can increase the adhesion and hiding power of the coating, and improve the performance and life of the coating.
3. Ceramic products: The slurry can be used to prepare ceramic products, and ceramic materials with specific properties can be prepared by molding and sintering processes.
4. Battery material: The slurry can be used as a battery material for the preparation of electrode sheets to improve the energy density and cycle life of the battery.

3. slurry application case

1. catalyst preparation: the active component and carrier material into a slurry, by dipping, spraying and other methods of the slurry on the carrier, the preparation of efficient catalyst. For example, platinum/carbon catalysts can uniformly disperse platinum nanoparticles on carbon carriers to improve the activity and stability of the catalyst, and are used in fuel cells, automobile exhaust purification and other fields.

2. Preparation of ceramic film: The ceramic slurry is coated on the substrate by doctor blade method, spin coating method and other processes, and the dense ceramic film is prepared by drying and sintering. Ceramic film has excellent heat resistance, corrosion resistance, insulation and other properties, can be used for high temperature environment, corrosion medium protection and functional applications.

3. Preparation of battery electrode material: the active material, conductive agent and binder are made into slurry, and the battery electrode sheet is made by coating, extrusion and other processes. The slurry method has the advantages of high production efficiency, low cost and stable product performance, and is widely used in the field of lithium-ion batteries, lead-acid batteries and other batteries.

4. conclusion

slurry as an important part in the field of chemical production raw materials, has a wide range of uses and good application prospects. Through the in-depth study of the properties of the slurry, the slurry preparation process can be further optimized to improve the performance and quality of the product. At the same time, with the continuous development of new technologies and new materials, the application of slurry in the field of chemical production raw materials will continue to expand.
