Principle |
Using a frequency of tens of thousands of times to hundreds of thousands of times the ultrasonic vibration, ultrasonic propagation in the liquid, when the energy is greater than 0.1W/cm2 when to pull the liquid molecules fragmented into voids, due to the surrounding pressure, air-based nuclear and crushed, crushed when cavitation nuclear huge impact on the surrounding formation, release of enormous energy, thus bringing down the object stripped of impurities, to achieve the purpose of cleaning. |
Water as a medium, the water system through the special equipment generates multi-beam, multi-angle, high-pressure water jets of varying intensity, to be scaling and cleaning equipment and fixtures to complete obstruction cutting, crushing, squeezing, washed in order to achieve the purpose of cleaning. |
The use of organic or inorganic detergent added to the device interface is clean, the insoluble scale, oil, etc. dispersed biological slime strip, while the reaction with the chemicals, materials or generate network and water-soluble salt, so as to achieve the purpose of cleaning . |
Low temperature dry ice pellets (-78 ℃), it has unique thermodynamic properties, when the impact of dry ice pellets to be cleaned by compressed air at the surface, so that rapid sublimation of dry ice, in thousandths of a second volume expansion within the nearly 800-fold. Parts to be washed with the same heat exchange surface, to achieve the purpose of cleaning the part surface. |
You can also clean any small gaps and holes, stripping and removal of oil and residue, so as to achieve high efficiency, water conservation, clean, dry and requirements. |
|
Feature |
Ultrasonic cleaning is mainly used for cleaning surfaces on the micro-particles, for conventional pollutants (such as dirt, grease, rust, etc.) cleaning poorly or not at all to achieve the purpose of cleaning. |
Booster pump or high pressure water jet is the source of energy, high-pressure pump directly affects the technical specifications of the water jet cleaning system, cleaning efficiency, quality and cost, energy consumption, and higher water quality requirements. |
The most original and most widely used methods. Acid or alkaline cleaning material for cleaning materials and equipment produced by corrosion. Wash down a long time, energy consumption. |
1 no secondary pollution, the cleaning process, clear down to recycle only the direct emissions can be re-used or dirt.
2 is currently only a few developed countries and regions, the use of specific industries. |
1 wide range of applications: such as machinery, paint, cold (heat) processing, electronics, food and other industries;
2.without any chemical media, green cleaning, water consumption is small;
3 economic and convenient. |
|
Pollution |
Water for washing medium, less polluting, such as the use of organic solvents, the pollution and more dangerous. |
Extremely polluted
(This method is gradually being phased out) |
Pollution, but also a special solvent parts and equipment for corrosion protection, the operator has some body damage. |
Installation of recovery can meet environmental requirements. |
Full compliance with environmental requirements |
|
Effect |
Certain situations better cleaning effect. |
Cleaning efficiency is low, the object for a particular cleaning, cleaning more difficult to select the appropriate parameters, and also for drying after washing. |
On the tube and the blind hole, deep hole can not handle, clean copper, aluminum and other nonferrous metals parts will change color, cleanliness after cleaning the surface of the poor parts. |
Without adding any cleaning solvents, direct cleaning effect of the fine. |
Is the current internationally recognized as the most efficient way of cleaning the best cleaning efficiency of 98%. |
|
Economic |
Higher equipment costs and consumption costs, process complexity. |
。 Equipment costs are low, consumption costs and environmental costs are high. |
Cleaning efficiency is low, the high cost of environmental protection. |
Due to the use of ultra-low temperature of dry ice, expensive, demanding equipment. |
Equipment costs and consumption, low cost, and no environmental costs. |
|
Remarks |
Difficult to grasp a variety of cleaning material required to be the best operating frequency, temperature, time, and appropriate media. |
Water quality is good or bad a great impact on the cleaning effect.Of the labor protection requirements of high technology services. |
Of wire, electronic and control components for damage, accelerated rusting equipment. |
Highly demanding work environment, the operator should pay attention to safety, cleaning must ensure good ventilation. |
Improve the working environment, reduce labor intensity and improve the cleaning efficiency and reduce consumption costs. |
