For nearly 10 years, ultrasonic cleaning equipment are moving in two aspects. One is that the various types of multi-cylinder or transmission chain or lift ultrasonic cleaning production lines have been market; Second, the low-frequency ultrasonic cleaning machines to the development of the high-frequency ultrasonic cleaning machines. In the United States, Japan, Europe and the Asia-Pacific market, multi-cylinder ultrasonic cleaning equipment showed a significant increase in the total potential of up to 50% of the total, while multi-station semi-automatic, fully automatic transmission chain or lift ultrasonic cleaning line The body equipment has also been increased to more than 40% of the total.
The application of ultrasonic cleaning technology has achieved good results. First, mechanical parts cleaning before the cleaning before and after plating or spraying overhaul cleaning of parts requiring high degree of cleaning, such as the oil pump and nozzle couplings, bearings, brakes, fuel filters, valves cleaning. Printed circuit board, wafers, wafers and components shell, seat rail system with signal control relay, components, connectors, CRT and electric vacuum devices such as cleaning. Glasses, microscopes, telescopes, sights and other optical systems and sample sheet glass cleaning. Various bottles of cleaning medical equipment, food, pharmaceutical, biochemical test. Spinneret, precision molds, precision rubber parts, jewelry crafts cleaning.
Our existing types of ultrasonic cleaning equipment manufacturing enterprises was nearly 40, but its distribution is mainly concentrated in the southeast coastal areas. Coastal manufacturers accounted for 85% of the national total, according to statistics, we can see that the economically developed regions of ultrasonic cleaning technology applications not only earlier, but also a wide range, a high degree of popularity of the same time, this once again shows the ultrasonic cleaning technology in the central and western regions popularizing The prospect is very broad. Product level, contemporary products compared with the 7080's of the 20th century, technological progress is obvious.
In recent years, due to the implementation of technological innovation of automotive brake production line, refrigerator compressor production line of traditional cleaning process, intends to adopt the ultrasonic cleaning process. Ultrasonic cleaning in front of the foreign automotive chassis frame cars shell spraying with special cleaning fluid, rust, go oxide film and the phosphide time cleaning processing is complete, drying to spray paint all have new applications and development.
American AdvancedSonicProctssingSvstems company, launched a series of a lot of cleaning coal or precious metal mineral equipment, such as the cleaning of the mineral soil surface of the metal particles, colloidal substances, the chemical agent to play a better role; wash pulverized coal ash handling to sulfur treatment rate for more than ten tons per hour.
The American Dvpont pharmaceutical factory in New Jersey report said: ultrasonic cleaning to remove dirt reaction tank or barrel shell surface chemical treatment, than with the ordinary method of energy conservation, low-cost and reduce environmental pollution, the cleaning process is simple, as long as the dissolved vessel filled with water, heated to 65 ° C, and addition of 2% of the surface active agent, for processing 24h, can be cleaned.
Some European manufacturers had cleaned 9.1m3 tank with methanol heated to boiling point for 48 hours at a time, to be a total of five washes in order to meet the requirements, that is able to meet the requirements and ultrasonic cleaning required only once, saving both solvent and improve efficiency and reduce environmental pollution.
With the increasingly wide range of applications of ultrasonic cleaning equipment, continue to refine and improve the novel ultrasonic cleaning equipment is being replaced by the old-fashioned equipment market.
MHz ultrasonic cleaning technology is to means using frequency 700KHz2MHz, ultrasonic cleaning. Cleaning system is generally made of a piezoelectric transducer display, the cleaning vessel and the cleaning liquid, high-frequency electric power generator and a control circuit, etc., for certain cleaning object, and sometimes also has hot-air drying, special cleaning frame (basket ) filtering and cleaning fluid circulation system.
MHz ultrasonic cleaning the main characteristics of the technology, to avoid a high finish surface of the object damage; two may be removed attached to the surface of the sub-micron sized particles; third is immersed in the liquid, oriented transducer can be washed , so both sides of the cleaning.
