Cleaning sink is in residual titanium cleaning product line, to hold to need the article and the clear water that clean, and the tank of the full-automatic residual titanium cleaning product line of customizing to industry is just very large.
Circulating pump, flowmeter, pressure gauge, liquid level gauge, intelligent dynamoelectric valve, ionometer, solar heating system and visual computer system form.
Technological process
The selection of the production line frequency of the residual titanium cleaning method of the present invention
Ultrasonic cavitation threshold values and hyperacoustic frequency have substantial connection, and frequency is higher, and the cavitation valve is higher.In other words, frequency is low, and cavitation more easily produces, and the compression that liquid is subject in the low frequency situation and rarefaction have the longer time interval, makes bubble can grow into larger size before collapse, increases cavitation intensity, is conducive to cleaning action.So cleaning, low frequency ultrasound is applicable to large parts surface or dirt and the high occasion of cleaning part surface conjunction degree.But perishable cleaning part surface, be not suitable for the highly polished parts of clean surface, and the cavitation noise is large.The frequency of 40KHZ left and right, under the identical sound intensity, the cavitation bubble quantity of generation is many while than frequency, being 20KHZ, penetration power is stronger, and should clean surface complex-shaped or the workpiece of blind hole is arranged, the cavitation noise be less, but cavitation intensity is lower, be applicable to cleaning the dirt occasion weak with being cleaned part surface conjunction power.High frequency ultrasound is cleaned and is applicable to computer, the meticulous cleaning of microelectronic element; The megahertz ultrasonic cleaning is applicable to the cleaning of IC chip, silicon chip and ripple film, can remove the micron, submicron order dirt and to cleaning part without any damage.Therefore from cleaning performance and economy, consider, frequency is chosen in 20-130KHZ scope.
The course of work
About " Ultrasonic Cleaning ": Ultrasonic Cleaning be utilize cavitation, acceleration effect and the direct flow effect of ultrasonic wave in liquid to liquid and dirt directly, indirectly effect, make that crud layer is dispersed, emulsification, peel off and reach the cleaning purpose.In residual titanium cleaning product line used, cavitation and direct flow effect are applied manyly.
Cavitation
Cavitation is exactly that the high frequency conversion mode of the ultrasonic wave compression stress more than 20,000 times and decompression power interactivity with per second is carried out transmission to liquid.In the decompression masterpiece used time, produce the phenomenon of vacuum nuclear colony bubble in liquid, when compression force, vacuum nuclear colony bubble produces powerful impulsive force while being stressed crushing, peels off thus the dirt on cleaned material surface, thereby reaches the accurate purpose of cleaning.
In the Ultrasonic Cleaning process, the bubble that naked eyes can be seen not is vacuum nuclear colony bubble, but air bubble, it produces inhibitory action to cavitation and reduces cleaning efficiency.Only have the air bubble in liquid fully to be taken off, the vacuum nuclear colony bubble of cavitation just can reach optimum efficiency.
Direct flow
Ultrasonic wave produces mobile phenomenon along the sonic propagation direction and is called direct flow in liquid.Intensity of acoustic wave is when 0.5W/cm2, and naked eyes can be seen direct flow, perpendicular to vibration plane, produces and flows, and flow velocity is about 10cm/s.By this direct flow, micro-greasy dirt dirt on cleaned material surface is stirred, the cleaning fluid on dirt surface also produces convection current, dissolves the lysate of dirt and mixes with new liquid, makes enhanced dissolution rate, to the carrying of dirt, plays a part very large.
Acceleration
Liquid particle promotes the acceleration produced.The higher residual titanium cleaning product line for frequency, cavitation is just very not remarkable, and cleaning is at this moment mainly clashed into particle by the acceleration under the liquid particle ultrasonication dirt is carried out to the ultraprecise cleaning.
