Operating precautions for benchtop large capacity centrifuges
1. Surface protection measures for benchtop large-capacity centrifuges: A basic idea for controlling corrosion is to isolate the corrosive environment. In the design of centrifuges, surface treatment methods such as flange, galvanizing, chrome plating, and electroless plating are often used. These methods are effective in many environments, but for rotating parts, an important phenomenon must be noted: matrix The material and the coating are two materials, and their linear expansion coefficients are different, which will produce different deformation amounts when the rotating member is elastically deformed, thereby causing a large number of microcracks; if the above phenomenon exists, the corrosion formation will be accelerated. Therefore, the method of surface protection for rotating parts should be used with caution.
2. the use of corrosion inhibitor centrifuge itself involves multi-discipline, the use of centrifuges, in addition to the above measures, should also pay attention to study its application environment. The application of corrosion inhibitors is also widely used in practical applications. For some harsh environments, the use of appropriate corrosion inhibitors can make the parts suitable. As long as the process permits, the use of corrosion inhibitors should be an effective way for centrifuge applications.
3. the selection of the material is very important for the desktop large-capacity centrifuge, because different materials and separation requirements, you need to choose different models. After the model and main parameters are determined, according to the corrosion resistance of different materials in different environments, comprehensive physical and chemical characteristics, cost performance and other factors, the strength parts and materials are determined from the basic surface. From the material itself, the target material it targets is safe.
