Today we will introduce you to the key step in the selection of electromagnetic flowmeters, that is, the choice of lining materials, the author will explain the name, characteristics and application of each material. Said electromagnetic flowmeter is the sales champion in all flowmeter products, I believe no one will object, it is widely used in urban water supply and drainage, water treatment, environmental protection and chemical industry, etc. with superior performance and high stability. field. And such a high-end atmospheric grade flow meter product, the price is very grounded relative to foreign products. Today we will introduce you to the key step in the selection of electromagnetic flowmeters, that is, the choice of lining materials, the author will explain the name, characteristics and application of each material. 1, ordinary rubber, natural rubber, soft rubber, hard rubber. Operating temperature 60 ° C, it is characterized by flexibility and good wear resistance. Generally used in urban water supply and drainage, etc., corrosion resistance is relatively poor. 2, polytetrafluoroethylene, also known as PTFE, also known as F4. One of the more commonly used lining materials, because of its chemical stability, is generally used for sanitary grade liquids or highly corrosive liquids, such as concentrated acid and alkali. 3. Polytetrafluoroethylene propylene, also called F46. This material is similar to PTFE, but its wear resistance is stronger than that of PTFE. The same medium temperature can reach 100 °C. 4, polyfluoroethylene, also known as Fs. Similar to the F4 material but with a slightly lower temperature, the medium temperature does not exceed 80 ° C, cost-effective, and the cost is lower than the F4 material. 5, neoprene, also known as CR, also known as Neoprene. It is characterized by good wear resistance and excellent elasticity, and is generally used in the fields of water supply and drainage, sewage treatment and the like. Corrosion resistance is slightly poor, and oxidation resistance is its disadvantage. 6, polyurethane rubber, also known as Polyurethane. It has excellent wear resistance, but it has insufficient ability for corrosiveness, and the temperature should not exceed 80 °C. It is generally used for the measurement of industrial and mining environments with high wear resistance requirements, such as slurry coal slurry. 7, ceramic material ceramic is undoubtedly the best of all materials, the absolute high-end products, the only drawback is that the price is not grounded, the production process is complex, the process requirements are extremely high, the price is super high. These are the commonly used lining materials for electromagnetic flowmeters. I hope that they will bring you some help, so that you will not be confused in the choice of lining.

Casting Machining Customized Cnc Parts is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various cold setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.
