Introduction of common ceramic nozzles and their uses

With the advancement of modern technology, ceramic nozzles are more and more widely used, and they have been continuously improved and updated. The following is introduced by Pintejin Ceramics. Zirconia ceramic machining nozzles We refer to the following types of ceramic nozzles in China: 1. Oxide ceramic nozzles (referring to alumina and zirconia materials) 2. Nitride ceramic nozzles (referring to silicon nitride combined with silicon carbide materials) 3. Silicon carbide ceramic nozzles (referring to silicon carbide, boron carbide materials) However, because the performance of oxide ceramic nozzles is not as good as that of silicon nitride nozzles and silicon carbide nozzles, they have been gradually eliminated. Ceramic nozzles are wear-resistant and chemical-resistant. The role of sprinkler irrigation in agriculture has changed the traditional sprinkler irrigation mode, making agricultural production gradually develop towards the road of science and technology. Since ceramic nozzles were introduced into China in the 1990s, they have been continuously improved in both shape and material: Shape: The shape of ceramic nozzles has gradually developed from the earliest spiral type, large volume, 2 turns of spray, to spiral type and eddy current type. ,Small size. Materials: Materials have gradually developed from oxide ceramics to nitride ceramics and carbide ceramics. Alumina Ceramic Nozzle Application of Ceramic Nozzle: Since the country launched the clear water and blue sky plan in 1998, the country has formulated a series of exhaust gas emission standards to control the emission of sulfide and nitride, because these are acidic gases, and they will be very strong in contact with water. Therefore, it is impossible for nozzles of general metal materials to meet the process requirements. At this time, silicon carbide nozzles fill the gap in the field. Another reason is that the lime slurry used in the wet desulfurization process has a strong erosion effect, and the silicon carbide material is resistant to corrosion, so silicon carbide nozzles are the first choice for desulfurization nozzles.
