Perovskite Organic Metal Halide Semiconductor Ultrasonic Coating Technology 110Khz High Frequency

Description:

Ultrasonic spraying has many advantages in the preparation of active layers. It can achieve high-speed, uniform, and continuous coating formation, allowing perovskite materials to be sprayed onto the substrate with higher quality and better coverage. In addition, ultrasonic spraying can also be carried out at low temperatures, which helps to avoid the problem of thermal decomposition or degradation of perovskite materials during high-temperature treatment.

Ultrasonic spraying technology can be used to form an interface modification layer to improve the contact between perovskite materials and battery substrates. For example, ultrasonic spraying can be used to spray conductive polymer materials onto the substrate to improve the electron transfer efficiency between perovskite materials and electrodes. This interface modification layer can also prevent unnecessary loss of electrons and ions, improving the performance of the battery.

Due to the sensitivity of perovskite materials to moisture and oxygen, ultrasonic spraying can be used to form a protective sealing layer on perovskite batteries. This sealing layer can prevent the infiltration of moisture and oxygen, thereby reducing the degradation and damage of perovskite materials. Ultrasonic spraying technology can achieve uniform coating distribution, ensuring effective protection of the entire battery surface.

Parameters:

When dealing with high solid content coatings, the following are some adjustment and optimization suggestions to adapt to ultrasonic spraying technology:

1. Spray pressure adjustment: High solid content coatings usually have higher viscosity and require greater pressure for effective spraying. Adjust the spraying pressure of the ultrasonic spraying equipment to increase the pressure so that the coating can be fully atomized and dispersed. Ensure that the spraying pressure is high enough to overcome the viscosity of the coating and achieve uniform coating application.

2. Liquid supply rate adjustment: High solid content coatings may require a higher liquid supply rate to ensure that the spraying equipment can continuously supply sufficient paint. Increasing the liquid supply rate can help overcome the viscosity of coatings and maintain the stability and continuity of the spraying process.

3. nozzle selection and size: Choosing the appropriate nozzle size is crucial for processing high solid content coatings. The size of the nozzle should be selected based on the viscosity and solid content of the coating to ensure smooth passage of the coating through the nozzle and uniform dispersion during the spraying process.

4. Preheating coating: For highly viscous and solid content coatings, preheating coating can reduce their viscosity, making them easier to be treated by ultrasonic spraying technology. By preheating the coating, the fluidity of the coating can be improved, and the spraying effect and coating quality can be improved.

5. Testing and optimization: It is very important to conduct actual testing and optimization for specific high solid content coatings. Through experiments and practical operations, the optimal ultrasonic spraying parameters and conditions can be determined to achieve the best coating effect and performance.

Please note that different high solid content coatings may have different characteristics and requirements, so the best adjustment and optimization methods may vary depending on the specific properties of the coatings. It is recommended to collaborate with coating suppliers and ultrasonic spraying equipment manufacturers, and conduct actual testing and verification to determine the most suitable ultrasonic spraying parameters and technology for specific high solid content coatings.
