Problems solved by technology

[0004] Although ultrasonic is easy to use and has good cleaning effect, it will cause certain corrosion or damage to the surface and interior of the cleaned material.
Especially for delicate parts or fragile materials, if they are corroded or damaged during cleaning, their performance will be greatly reduced

Embodiment Construction

[0019] The invention discloses an ultrasonic cleaning method, which is specifically as follows:

[0020] Prepare a multiphase flow and distribute the multiphase flow on the surface of the object to be cleaned at a certain flow rate; wherein the multiphase flow includes a continuous phase and a dispersed phase, the continuous phase is liquid, and at least one of the dispersed phases is gas, and the gas is initially in the form of Microbubble;

[0021] Start the ultrasonic generator to emit ultrasonic waves, and the ultrasonic waves will reach the surface to be cleaned after propagating in the multiphase flow; adjust the ultrasonic frequency to Make the multiphase flow form a higher impedance ultrasonic retardation layer on the surface of the object to be cleaned, where, 0.1<k<0.5, P is the initial static pressure in the multiphase flow, R is the initial average radius of the gas microbubble, and ρ is The density of the continuous phase. The ultrasonic waves emitted by the so...

Abstract

The invention relates to a ultrasonic cleaning method. Firstly, a multi-phase flow is prepared, and is distributed on the surface of an object to be cleaned with a certain flowing speed, wherein the multi-phase flow comprises a continuous phase and a dispersion phase; the continuous phase is liquid; the dispersion phase contains gas; the gas in the multi-phase flow is initially in a micro-bubble state; then, a ultrasonic generator is started to emit ultrasonic waves to the cleaned object; the ultrasonic waves are propagated in the multi-phase flow to reach the cleaned object; and the initial frequency of the ultrasonic waves is adjusted as FORMULA, so that the multi-phase flow forms a ultrasonic retardant layer with higher resistance on the surface of the cleaned object. The ultrasonic cleaning method can improve the cleaning effect of the cleaned object, and meanwhile, can prevent the surface and internal damage of the cleaned object.

Description

technical field [0001] The invention relates to a cleaning method, in particular to an ultrasonic cleaning method. Background technique [0002] Ultrasound is a form of transmission of mechanical vibrational energy. Utilizing the cavitation, acceleration and straight-flow effects of ultrasonic waves in the liquid to directly and indirectly affect the liquid and dirt, the dirt layer can be dispersed, emulsified, and peeled off to achieve the purpose of cleaning. At present, ultrasonic cleaning has been widely used in various industrial and civil fields, including surface spraying treatment industry, machinery industry, electronics industry, medical industry, semiconductor industry, watch and jewelry industry, optical industry, textile printing and dyeing industry. [0003] When cleaning with ultrasonic waves, the ultrasonic generator generates high-frequency ultrasonic waves, which generate impact and friction during the propagation of ultrasonic vibrations, thereby removing...
