If the particle size of a powder is a key indicator of a product or raw material (mainly the particle size distribution affects the performance of the product), a particle size analyzer is required to detect the particle size distribution.
The particle size analyzer is a testing device for detecting the thickness of the powder incoming material. The enterprises applying the particle size analyzer can be roughly divided into three categories:
First, powder product manufacturers, such as cement companies, pesticide companies, battery materials companies, pharmaceutical companies, non-metallic mineral powder production enterprises, metal powder production enterprises, and so on. The purpose of the particle size analyzer for powder production enterprises is to control the quality of powder products in the production process to ensure product quality and energy saving.
The second is the application of powder products, including papermaking enterprises, coatings enterprises, ceramic enterprises, refractory enterprises and plastics and rubber petrochemical enterprises. The purpose of the powder application enterprise particle size analyzer is to control the quality of the powder raw materials entering the factory - the particle size distribution is stable and uniform, thus ensuring the final product quality.
The third is the use of universities and research institutions for powder materials research. The advantage of using a particle size analyzer in the research field is that it can know the particle size change of the powder material during the test, so as to select the best performance powder material and optimize the preparation technology.
In short, the particle size analyzer is a routine quality inspection method in the field of powder production, application and research. The use of a particle size analyzer can stabilize the product quality, improve product performance, reduce energy consumption, and improve production efficiency.
Chengdu Jingxin laser particle size analyzer can measure nanometer and micron powder. Each type of particle size analyzer has good repeatability and high precision (such as JL-1177 type, JL-1197 type). The products are sold well both at home and abroad, and are highly praised by customers in the use of enterprises and colleges.
