Nowadays, many friends don't know if this piezoelectric ceramic is a good building material used in some places, especially friends who want to know what features of this piezoelectric ceramic and so on. Next, Xiaobian will introduce you to the introduction. What is the working principle of this piezoelectric ceramic , and what kind of production process is it, and what our friends still need to understand is the characteristics of piezoelectric ceramics. Not much.
First, the working principle of piezoelectric ceramics
1. The principle of piezoelectric ceramics is that there is some tension on the ceramic sheet, so that a kind of electric charge with opposite polarity is generated at both ends of the ceramic piece, so that it becomes a current through the loop.
2, this effect is called the piezoelectric effect, if this piezoelectric ceramic is made, in the transducer placed in the water, then the functional effect of the sound wave will make our two ends will soon induce the charge, this It is the receiver of the sound wave.
3. The piezoelectric effect is reversible. For example, an alternating electric field is applied to the piezoelectric ceramic sheet, and the ceramic sheet is sometimes thinned and thickened, and vibration and sound waves are generated.
Second, the production process
1, the ingredients are processed before the material, remove the moisture and then need to according to the formula ratio and various raw materials, pay attention to a small amount of additives should be placed in the middle of the bulk.
2. The purpose of mixing and grinding is to uniformly mill several raw materials and then burn them to complete the reaction conditions of complete solid reaction. Generally, dry grinding and wet grinding are adopted.
3, small batches can also be used to dry so that these large quantities can be used to stir the ball mill and airflow crushing method, I believe this efficiency is very high.
4. The purpose of this pre-firing is to form a piezoelectric ceramic by reacting the raw materials in each of the high temperatures.
Third, the characteristics of piezoelectric ceramics
1. The converter between the sound converters is one of the most common situations, such as some of our pickups, microphones, cell phone headsets, buzzers, ultrasonic depth detectors and sonar materials. Use piezoelectric ceramics as a beautiful converter for sound.
2. There are also buzzers that can be exemplified on our children's toys. This is how our currents vibrate through the inverse piezoelectricity of piezoelectric ceramics, and the sound that our ears can hear.
3. Piezoelectric ceramics can generate different kinds of high and low frequency vibrations through certain control of electronic circuits, thus emitting various kinds of different sounds.
4. For example, some of our electronic music greeting cards convert the AC audio signal into a good sound signal through the inverse piezoelectric effect.
Now our piezoelectric ceramics is exactly what kind of raw materials and how it helps in our lives, as well as the characteristics of piezoelectric ceramics and working principles, etc. I believe friends have already understood Clear. Now everyone else wants to know other decorative information, our decoration home network welcomes everyone to pay attention.
