1. Imports and domestic disputes: ultrasonic components, are available in China, why import them? Of course, some imported components are necessary, such as integrated modules, because the domestic product level is not the same as the foreign level, but many manufacturers technical data said: the sensor is imported from a Germany cleantech brand, how is that possible, there are many domestic sensor manufacturers, the price is lower than the import, like the cheap Chinese how to choose to import? The use of domestic brands, the level is very low, there is no brand, one of the reasons for fraudulent prices: the report plans to say that imports, but the actual domestic production.
2. Practical Power Dispute: the ultrasonic power is calculated according to the actual volume of the groove. The power of the standard machine is calculated from the practical power of the bottom region. Some manufacturers often report high power (now more than practical power needs) when quoting prices that are very low, giving customers a sense of being very cheap, but in actual production, usually 60-70% of the reported power, customers are not cheap. This is one way. The other way is the vibrating plate. Because it is sealed, the actual power of the vibrating plate is questionable. Speculative manufacturers often weld screws in them, but do not install sensors. In this case, is the actual power of your ultrasound still the power you agree with? It is also reported a power of 60%-70%, this will give customers a cheap and affordable image, but you will suffer more losses in practice.
3. Practical data dispute: the full-automatic ultrasonic cleaning machine is mainly composed of stainless steel plate, the inner groove is generally 304, has the special request to use 316L, does not have the liquid direct contact with the outer seal plate is also made by 304, use a kind of called stainless steel plate (201 or 202) to deceive the customer, the outer surface can not be seen, because it is also very shiny, but after a few months of use, will be seriously rusted, affecting the appearance.
This is the recent ultrasonic cleaning operation in some of the details, and more and more serious. We invite our customers not to believe in cheap prices. Cleaning equipment, just like ordinary consumer goods, is too low the quality of the price should be carefully examined.
What are the important factors that affect the automatic ultrasonic cleaning machine?
Frequency
In addition to washing device differences, choose ultrasonic frequency differences. Hardware, equipment, steam friction, refrigeration compressor, and other areas of heavy environmental pollution like the usual cleaning of objects most choose 20KHz frequency cleaner; Electronic optics, optoelectronic materials, circuit boards, practice rooms, and other daily necessities are mostly 40 kHz frequencies; the frequency of smart computer microelectronic components, integrated circuit chips, single-crystal silicon wafers, and wave films are mostly more than 80 kHz, can remove μm, sub-micron stain and cleaning test, no damage.
2. Output power of automatic hydrocarbon ultrasonic cleaning machine
At present, the mass volume of the general reference materials in our plant is positively correlated with the ultrasonic output power (ultrasonic output power is 0.3-0.5 w/CM2) High-power materials are mostly used in hardware, equipment, and other areas of cleaning or heavy environmental pollution (ultrasonic output power of 0.5-1W/CM2).
Time
In addition, the washing equipment should be set differently. In addition, the consistent washing time (10-20 min) is beneficial to the better washing of the samples, and the longer automatic ultrasonic cleaning production line time will cause the appearance of the washed samples to appear color spots, and prevent smooth appearance. The time is too short to wipe.
4. temperature
Due to the different physical-chemical characteristics of each piece of equipment, U has to choose a different washing temperature when washing through the ultrasonic cleaning line, such as vegetable oils and fats, more than 50 â ° C on weekdays, ultrasonic scrubbers are usually 40 ° C dear friends, if the temperature is too high, it will produce oxidation spots in the air; less than 15 ° C is usually suitable for rough edges.
5. detergent
Contemporary ultrasonic detergents are mixtures of various scale detergents, wetting agents, and other reactive ingredients. There are many excellent and purposeful detergents to choose from. The accurate choice of detergent is the key to achieving a proper washing effect and avoiding the reaction between detergent and washing equipment.
