Particle size analysis is the process of studying and evaluating the size of the particles contained in a product.
Through this analysis, the physical properties and performance characteristics of the product can be understood, and the quality and function of the product can be deeply analyzed.
Particle size analysis is described in detail below.
1. Definition and importance of particle size Particle size refers to the size range of particles in the product.
Particle size has a significant impact on the performance and functionality of a product.
Particles of different sizes exhibit different characteristics during use, including the surface area of the particles, bulk density, and interactions between particles.
The analysis of particle size can help us better understand the characteristics of the product and provide a basis for product improvement.
Second, the method of particle size analysis 1Laser particle size analysisLaser particle size analysis is a commonly used particle size analysis method.
By using the principle of laser scattering, the size distribution of particles in liquids or gases can be measured.
This method has the advantages of fast analysis, accurate data and easy operation, and is widely used in various fields.
2.Optical microscopyOptical microscopy is an intuitive method for particle size analysis.
The particles in the sample are observed by using an optical microscope and an image of the particles is obtained using micromicrography techniques.
By measuring the size of the particles in the image, the size distribution of the particles can be calculated.
3.Electron microscopyElectron microscopy is a high-resolution method for particle size analysis.
By using an electron microscope to observe the particles in the sample and utilizing the high-resolution images of the electron microscope, the diameter and shape of the particles can be accurately measured.
3. Application fields of particle size analysisParticle size analysis is widely used in various fields, such as medicine, chemical industry, food, etc.
