The oxidized anodized film of sulfuric acid is colorless. After the anode part is filled with hot water, it is easy to get fingerprints and watermarks, and the film layer is white. The reason may be: 1 closed temperature and time is not enough; 2 pH is wrong; 3 There is too much aluminum hydroxide in the solution. The corresponding processing method: 1 production according to process specifications; 2 adjust the pH value; 3 Replace the water. Concerned about surprises Label: Anodized Sulfuric acid Coating Hot water pH Previous: What is the original sulphuric acid oxidized film that can be wiped off? Next: How to apply insulating rubber?
Pressure sensor usually consists of a pressure sensor and a signal processing unit for measuring the pressure of liquids and gases.
According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. According to the working principle, it can be divided into Ceramic Pressure Sensor, diffusion silicon pressure sensor, piezoresistive pressure sensor, sapphire pressure sensor and so on.
