Vibration Wave Ultrasonic Dispersion Reactor 20Khz For Industrial Preparation Of Nanomaterial Particles

Introduction of vibrating rod of ultrasonic cleaning machine:

Ultrasound refers to electromagnetic waves with a frequency of about 20 kHz to 50 MHz. It is a mechanical wave and requires an energy carrier—a medium—to propagate. There is an alternating period of positive and negative pressure in the ultrasonic transmission process. In the positive phase, the medium molecules are squeezed to increase the original density of the medium; in the negative phase, the medium molecules are sparse and discrete, and the medium density decreases. In other words, ultrasonic waves cannot polarize the molecules in the sample, but generate acoustic cavitation between the solvent and the sample, leading to the formation, growth, and burst compression of bubbles in the solution, thereby dispersing and increasing the solid sample. The contact area between the sample and the extraction solvent increases the mass transfer rate of the target from the solid phase to the liquid phase. In terms of industrial applications, the use of ultrasonic waves for cleaning, drying, sterilization, atomization and non-destructive testing is a very mature and widely used technology.

Ultrasonic vibrating rod uses a high-power and large-amplitude transducer to generate radial vibrations on the rod body. Ultrasonic waves are uniformly generated 360° near the vibrating rod. Its amplitude is between the ultrasonic cleaning machine and the processor. Therefore, use The direction is more flexible. The ultrasonic vibrating rod can be used for any tank cleaning, it can be placed in any position of the cleaning tank, and it occupies a small volume space and can be used very flexibly. Used inside the reactor, it can be used to accelerate the dissolution, accelerate the reaction and prevent the inner wall from scaling.

Ultrasonic vibrating rods are widely used in the fields of ultrasonic homogenization, ultrasonic dispersion, ultrasonic emulsification, ultrasonic cell crushing, ultrasonic extraction and separation, ultrasonic exhaust, and accelerated chemical reactions of liquid-liquid and liquid-solid materials. Specific industries include:

1) Fuel: Emulsification of fuel oil mixed with water to save fuel and reduce exhaust pollution.

2) Food: Emulsification by adding sugar to milk, emulsification of ghee to make high-grade lactose, dispersion of raw materials during sauce manufacturing, etc.

3) Cosmetics: emulsify wax, paraffin, etc., to make detergent, shampoo, lotion and other oil to disperse particles.

4) Lubricant: the emulsification of rolling oil, the manufacture of emulsion used for cooling and lubrication during sheet metal rolling.

5) Coating: emulsification of waterproof coating agent for packaging, emulsification of polyethylene in water, emulsification of waterproofing agent, emulsification of resin processing fluid for fishing nets.

6) Chemical industry: accelerate the speed of chemical reaction, dispersion in the production of fluorescent materials and photosensitive materials, etc.

7) Medicine: Extraction of effective ingredients of Chinese herbal medicine.

8) Environmental protection: sewage treatment.
