Component	Characteristic	Parameter
E-2000 Powder feeder	1. The powder feeder is a high-precision powder feeding mechanism based on the principle of toothed dial with vibration structure and gravity falling, with uniform powder output and wide particle size range. 2. After the top cover is sealed, the powder condition in the powder cylinder can be clearly seen through the visual transparent observation window on the powder cylinder. 3. Nitrogen or argon with small flow is used as powder gas. The powder is rotated to the powder outlet along with the powder tray at the bottom and enters into the spray gun together with the powder gas. 4. Adopting the latest international turnover structure, it is convenient to clean the powder, which can be discharged from the lower mouth, or can be poured from the barrel body.	1. Powder feeding: toothed dial 2. Cleaning method: barrel body flip 3. Volume of powder storage tube :2L 4. Powder feed gas: nitrogen 5. Powder feeding air pressure: 0.15-1.2mpa 6.

HA-2000 has many functions and features, and its advantages are mainly reflected in the following aspects:
1) Touch screen operation, the design structure of the equipment adopts full closed-loop automatic control structure, the gas is all controlled by pressure sensors imported from the United States and pressure regulating valves imported from Japan, the pressure can be monitored in real time and automatically reach the set value of the process.
2) The fuel is propane and the combustion-supporting agent is air, which is the safest combustion mode among the gas models in the market at present;
3) The structure of the spray gun is designed according to the principle of the rocket generator. The flame flow speed reaches over 2000m/s, with large output power and stepless adjustment;
4) The spray gun adopts axial center powder feeding. This new injection method makes the powder dissolve well and distribute evenly in the whole flame, which improves the coverage efficiency and coating quality;
5) It has the function of process recipe storage and invocation. Parameters can be added, modified and saved.
6) The system fuel adopts full closed-loop design, modular design, high-performance PLC control, safe and simple operation;
7) The coating produced has excellent performance with low porosity less than 1% (average porosity less than 0.5%) and high spray efficiency (up to 30KG powder per hour).

When the blade dryer used for a long time, the blade dryer will appear corrosion phenomenon, then, what is the reason for this phenomenon?

A, the corrosion of the biaxial blade dryer is mainly due to the production material of the biaxial blade dryer is metal, and the chemical activity of the metal is relatively high, when the metal is exposed to the wet air for a long time, the oxidation reaction of the metal will occur, and then the corrosion will occur. The production of metal materials of biaxial blade driers is different, and the ease of their oxidation reaction is different.

B, the more pure metal made of the biaxial blade dryer is not easy to be corroded, when the more impurities in the metal, the more easily the biaxial blade dryer is corroded.

C, when the shape of the internal parts of the biaxial blade dryer is more complex and the surface is more rough, then its corrosion resistance is worse. When the corrosion of the internal parts occurs, it will soon cause the corrosion of the metal in contact with the parts, and the corrosion speed is very fast.

D, when the working environment of the biaxial blade dryer is high temperature, high humidity, or more oxygen and chloride ions in the environment, it is easy to react with the biaxial blade dryer, accelerate the corrosion degree of the biaxial blade dryer.

The paddle shaft, paddle blade and groove in the sludge dryer of Mitsubishi Heavy Industry of Japan successfully are coated with wear-resistant, corrosion-resistant and high-temperature tungsten carbide coating by supersonic spraying. After continuous use and tracking by customers, the service life of the components has been greatly improved.
