In the ceramic manufacturing industry, the particle size and distribution of raw material particles are one of the key factors determining product quality and performance. The particle size uniformity of ceramic powder directly affects the density of the green body, the mechanical strength after sintering, and the surface quality of the final product. In recent years, with the advancement of materials science and the innovation of detection technology, wet laser particle size analyzer has been widely used in the field of ceramic detection due to its high precision and fast analysis characteristics.

Working principle and advantages of wet laser particle size analyzer

Wet laser particle size analyzer is an analytical instrument designed based on the principle of laser diffraction. It measures the scattered light intensity distribution of particles on the laser beam and converts the particle size and distribution. Compared with dry testing, wet testing uses liquid as a dispersing medium, effectively avoiding agglomeration between particles and ensuring the accuracy and repeatability of test results. Its unique wet circulation dispersion system adopts a pipeline residue free design, avoiding particle deposition and ensuring a clean and stable testing environment.

Specific Applications in Ceramic Testing

Raw material quality control

In ceramic production, the particle size distribution of raw materials such as alumina, zirconia and other powders has a direct impact on the sintering performance and mechanical strength of the product. Wet laser particle size analyzer can quickly and accurately determine the particle size distribution of these raw materials, helping manufacturers strictly control the quality of raw materials and avoid problems such as inconsistent sintering shrinkage and product cracking caused by uneven particle size. For example, in the production of alumina ceramics, wet laser particle size analyzer detection can ensure uniform particle size of raw materials, thereby improving the density and mechanical properties after sintering.

Optimization of sintering process

The sintering process of ceramics is significantly affected by the particle size of the raw materials. Fine particle raw materials hydrate quickly and have high early strength, but internal stress concentration may occur due to rapid sintering; Coarse grained raw materials have slow hydration and contribute significantly to later strength, but insufficient sintering may result in insufficient product strength. The wet laser particle size analyzer can monitor the changes in particle size during the sintering process in real time, providing data support for optimizing the sintering process. By adjusting the sintering temperature and time, manufacturers can precisely control the microstructure of the product and improve its performance.

Product development and innovation

In the research and development process of ceramic new materials, wet laser particle size analyzer also plays an important role. By testing raw materials with different particle size distributions, researchers can explore the influence of particle size on the properties of ceramic materials, providing theoretical basis for the development of new materials. For example, in the development of high-performance ceramic coatings, analyzing the particle size of pigments and fillers using a wet laser particle size analyzer can optimize the coating's coverage, glossiness, and corrosion resistance.
