Basic parameters of ultrasonic cleaning machine
Ultrasonic cleaning is based on the role of cavitation, then many bubbles in the cleaning fluid quickly generated and immediately imploded. The resulting impact will be submerged in the cleaning solution of the workpiece inside and outside the surface layer of the waste off. Along with the ultrasound frequency increases, the number of bubbles increases and the bursting force becomes weaker, therefore, high-frequency ultrasound is particularly suitable for particle stain cleaning without breaking the surface of the workpiece. All ultrasonic cleaning system needs to have three basic components: the tank to store the cleaning fluid, the electrical energy into mechanical energy transducer and its generation of high-frequency electrical signal ultrasonic generator.
(1) Frequency: ≥ 20KHz, can be divided into low-frequency, medium-frequency, high-frequency 3 kinds.
(2) cleaning medium: the use of ultrasonic cleaning, generally two types of cleaning agents: chemical agents, water-based cleaning solutions. Cleaning medium of the chemical effect, can accelerate the ultrasonic cleaning efficacy, ultrasonic cleaning is the physical effect, the combination of the two roles, and then on the items for in-depth, complete and thorough cleaning.
(3) power density: power density = launch power (W) / launch area (cm2) generally ≥ 0.3W/cm2, the higher the power density of ultrasonic waves, the stronger the efficacy of cavitation, the faster the speed, the better the cleaning effect. But for the precision, surface smoothness of the items, the use of long-term high power density cleaning will allow the surface of the items to produce "cavitation" corrosion.
(4) ultrasonic frequency: the lower the ultrasonic frequency, the cavitation generated in the liquid is easier to produce a large force, the role of the stronger, mainly for workpiece (coarse, dirty) cleaning. Higher frequency is ultrasonic wave direction, mainly used for detailed cleaning of goods.
(5) cleaning temperature: Usually, super based on sound waves at 30 ℃ -40 ℃ when the cavitation effect is the best. Cleaning agent, on the other hand, the higher the temperature, the more pronounced the effect. General practical application of ultrasound, the use of 50 ℃ -70 ℃ operating temperature.
Ultrasonic cleaning machine use specifications:
(1) ultrasonic cleaning machine power supply and heater power supply must have excellent grounding protection device.
(2) ultrasonic cleaning machine cleaning cylinder does not add a certain amount of cleaning fluid, do not start the ultrasonic switch.
(3) heating equipment cleaning equipment is strictly prohibited when no liquid open heating switch.
(4) It is strictly prohibited to use heavy objects (iron) collision cleaning cylinder bottom, in order to prevent damage to the energy converter chip.
(5) ultrasonic generator power supply should be used all the way 220V/50Hz power supply and equipped with more than 2000W voltage regulator.
(6) cleaning cylinder cylinder bottom should be cleaned frequently, not too much impurities or stains.
(7) Every time you change the new liquid, to be ultrasonic start, you can clean the parts.
Ultrasonic cleaning machine related to the selection of cleaning agents:
All in the discussion of ultrasonic cleaning agent preparation, the most important thing is to recall the cleaning principle of cleaning agents on the dirt and cleaning process. Despite the long history of washing, but because the washing process and the system is highly complex, so far the theoretical community still only has the essence of the investigation but the washing process is difficult to achieve data control. Mainly because the solution system is a multi-phase dispersion system. The dispersing medium is also a complex solution with a variety of components: the surfaces and interfaces involved in the system, and the nature of their stains are extremely complex.
Ultrasonic cleaning machine cleaning agent used for liquid detergent, the composition mode: the surface active agent, redundant agent, other additives. A substance when it is dissolved in water even if the concentration is very small, can significantly reduce the surface tension of water and air, or water and other substances of the interfacial tension, the substance is called surfactant. Depending on the electrical properties of the hydrophilic groups of the surfactant when it is dissolved in water, the surfactant can be categorized into anionic, cationic, neutral and amphoteric surfactants.
The addition of a certain additives, and then play the following roles: 1, buffering: so that the pH value of the detergent can be maintained stable. 2, corrosion-resistant effect on the metal. 3, can increase the detergent's emulsification capacity and emulsion stability. 4, can make the solution has a very good ability to suspend the ability to stabilize the suspension system can prevent the stains from settling once again. Selection principles of surface activator, stinging agent and additives: (1) the detergent has strong cleaning ability; (2) the chemical nature is soft and does not damage the washed material; (3) there is no chemical interaction between the two components and thus the components are invalidated; (4) it has good rinsing property. Formulation of the use of washing liquid temperature and concentration should be determined by specific experiments. The role of solvent-based cleaning agent is to achieve the purpose of cleaning by dissolving the glue, wax, asphalt on it. Therefore, in the ultrasonic cleaning needs to be based on the characteristics of the cleaning object dirt, select the appropriate cleaning agent, only select the appropriate cleaning agent to achieve satisfactory cleaning results.
Other applications of ultrasonic cleaning machine
Ultrasonic cleaning machine in addition to cleaning, but also can be commonly used in degassing, defoaming, emulsification, mixing, replacement, extraction, powder crushing and cell crushing. In this liquid phase degassing has become one of the main applications of ultrasonic cleaning machine in addition to cleaning, has become one of the necessary tools for liquid phase instruments.
