Power Generation/Heating Sensor Piezo Atomizer Manufacturers

What special processes are used to optimize the piezoelectric properties and mechanical strength of the material during the processing of the piezo atomizer disc of the power generation/heating sensor?

1. Material selection and pretreatment
Before the processing begins, it is the basis to select the appropriate piezoelectric ceramic material. High-quality piezoelectric ceramic materials should have high piezoelectric constants, low dielectric losses and good mechanical properties.
In the material pretreatment stage, the piezoelectric ceramics may need to be sintered, polarized and other treatments. The sintering process can optimize the microstructure of the ceramics, improve their density and mechanical strength; while the polarization process is the key step to enable the piezoelectric ceramics to obtain piezoelectric properties. By precisely controlling the conditions of sintering and polarization, the performance of piezoelectric ceramics can be significantly improved.

2. Special processes to optimize piezoelectric performance
In the processing of piezoelectric ceramic discs, precision molding and cutting are the key to ensuring product accuracy. The use of advanced molding technology and high-precision cutting equipment, such as automatic laser drilling machines and pneumatic embossing machines, ensures that each disc can achieve extremely high dimensional accuracy and shape accuracy. This not only helps to improve the piezoelectric performance of the product, but also reduces the accumulation of errors in subsequent processing.
After initial forming and cutting, the piezoelectric ceramic discs are also finely ground and polished. This process can further remove surface defects and improve surface finish, thereby improving piezoelectric performance.
For some complex application scenarios, such as power generation sensors and piezo atomizers, piezoelectric ceramics with multilayer structures may be required. This design can achieve specific performance requirements by superimposing piezoelectric ceramic layers with different performances. Haining Saida Piezoelectric Ceramics Co., Ltd. has accumulated rich experience in multilayer structure design and can customize the optimal number of layers and interlayer connection methods according to customer requirements, thereby maximizing piezoelectric performance while ensuring mechanical strength.
High-temperature annealing and heat treatment are important means to optimize the performance of piezoelectric ceramics. By precisely controlling the annealing temperature and holding time, the residual stress inside the ceramic can be further eliminated, the crystal structure can be optimized, and the piezoelectric constant and mechanical strength can be improved.

3. Special process to optimize mechanical strength
In the design of piezoelectric ceramic discs, their mechanical strength can be enhanced through reasonable structural design. For example, adding reinforcing ribs to the edge of the disc or using other forms of reinforcement structures can effectively improve the bending strength and impact resistance of the disc.
Surface coating can not only improve the corrosion resistance of piezoelectric ceramics, but also enhance their mechanical strength to a certain extent. Using advanced coating technology, a uniform and dense protective layer is coated on the surface of piezoelectric ceramics, which effectively prevents the external environment from eroding the ceramics. The coating can also play a role in lubrication and friction reduction, which helps to extend the service life of the product.
In some high-end applications, piezoelectric ceramics may need to be compounded with other materials (such as metals, polymer materials, etc.) to enhance their mechanical properties. Haining Saida Piezoelectric Ceramics Co., Ltd. has in-depth research and exploration in composite reinforcement technology and can provide customized solutions according to customer requirements. Through reasonable material selection and structural design, the perfect combination of piezoelectric ceramics and composite materials can be achieved, thereby significantly improving mechanical strength while ensuring piezoelectric performance.

4. Quality Control and Inspection
During the processing process, quality control and inspection are key links to ensure product performance. Haining Saida Piezoelectric Ceramics Co., Ltd. is well aware of this, so it will conduct corresponding inspections after each process. For the final product, the company will conduct 99.99% full inspection according to customer requirements and international standards to ensure that each product can achieve the best performance state. In addition, the company also has sophisticated production equipment and complete testing equipment, such as tensile testing machines, ultrasonic impedance analyzers and image measuring instruments, which can monitor and evaluate the performance parameters and mechanical strength of products in real time.
