A detergent for a variety of cleaning products:
1. Clean circuit boards with alcohol or water
2. Clean your glasses with water or special glasses
3, rust removal powder;
4. Oil-removing powder for oil removal;
5. Using wax remover to remove wax;
6. Clean some copper products with vinegar (weak acid detergent).
7. Use a dewaxing agent to clean some of the polished metal
8, silver blackening articles with silver washing water;
9, can use vinegar to clean ceramic articles;
Grease on rubber parts: detergent or metal rust remover can be used.
Generally speaking, the solvent-type corrosion is big, and the water-based corrosion is small. Generally speaking, it is recommended to use oil remover directly for oil removal. Ultrasonic waves travel through the liquid, causing the liquid and the cleaning tank to vibrate at ultrasonic frequencies. The liquid and the cleaning tank have their natural vibration frequencies. This is the sound frequency, so people hear the hum. With the development of the cleaning industry, more and more industries and enterprises are applying small ultrasonic cleaning machines. Small ultrasonic cleaning machine ultrasonic cleaning effect is good, simple operation. The sound that people hear is a frequency of 20-20,000 Hz sound signal is higher than 20,000 Hz sound wave is called an ultrasonic wave, sound wave propagates vertically according to a sinusoidal curve, and produces a lot of small bubbles. One reason is that the local tensile stress of the liquid creates negative pressure, and the pressure drop causes the gas dissolved in the liquid to supersaturate, escape from the liquid, and become small bubbles; the other reason is that the strong tensile stress tears the liquid into cavities, it's called cavitation.
What is the use of a small ultrasonic cleaning machine?
I believe that friends who wear glasses usually have the phenomenon of yellowing and turning green after wearing the nose pads of glasses for a long time. It looks dirty and dirty, and some gaps are not cleaned with hand tools, so it is very difficult to clean them, in addition to spending time going to the shop to clean glasses, but also very troublesome small ultrasonic cleaning machine can quickly solve this problem.
A small ultrasonic cleaning machine not only can clean glasses, but also can clean jewelry, make-up tools, and a series of things, to avoid our cleaning trouble, and even clean fruits and vegetables.
The principle of the ultrasonic cleaning machine is the high-frequency vibration signal from the ultrasonic generator, which is transferred to high-frequency mechanical vibration by the sensor and spread to the cleaning solvent. The ultrasonic wave radiates intensively forward in the cleaning liquid, which makes the liquid flow and produces tens of thousands of small bubbles existing in the 50-500 μm diameter liquid to vibrate under the action of the acoustic field. These bubbles form and grow in the negative pressure region of ultrasonic longitudinal propagation. In the barotropic region, when the sound pressure reaches a certain value, the bubble increases rapidly and then suddenly closes. When the bubble closes, it creates a shock wave that creates thousands of atmospheres around it, destroying the insoluble dirt and dispersing it in the cleaning fluid. When the particles are coated with oil and adhered to the surface of the cleaning part, the oil is emulsified, the solid particles are separated, and the cleaning part is purified.
We don't understand so many technical terms. In short, the principle of an ultrasonic cleaning machine is ultrasonic air produces small bubbles, and then water molecules burst, and peel off the stain.
Small ultrasonic cleaning machine for cleaning what?
1 glass (not recommended to use an ultrasonic cleaning machine to clean coated glasses, easy to damage the lens)
2 jewelry (in addition to pearls, tortoiseshell, and jade, with the ultrasonic cleaning machine cleaning easily damaged)
3 combs
4 razors
5 small toys
6 watch chain
7 small objects rust (if the cleaning fluid is in the addition of rust remover, you can also rust)
The advantages of a small ultrasonic cleaning machine are as follows:
1 ultrasonic cleaning machine cleaning speed, good effect, for stubborn oil, fingerprints, perspiration, oxidation layer has a very good cleaning effect
It is very difficult for us to clean up the oil in the crevice by hand. Ultrasonic cleaning machine so easy, and the operation of the machine is also very simple
Points for attention in the use of small ultrasonic cleaning machines:
1 it is best to use pure water to add water to the cleaning pool. You can buy Wahaha or Ipoh Pure Water in the supermarket, do not reuse water, because the impurities generated after cleaning particles will wear out in the ultrasonic environment lens;
2 liquid level to immerse the parts to be cleaned shall prevail, generally not more than three-quarters of the cleaning pool. Usually, the machine wall will mark the maximum water level;
3 ultrasonic can clean accurately, but the ability to treat mud dirt is weak. Therefore, if there is yellow mud or watery mud dirt on the articles to be cleaned, it should be treated before being put into the ultrasonic cleaning machine;
4 after cleaning, need to pour out the water-washed items. It is best to clean the inner wall of the machine with clean water, and wipe the inner wall with a cloth or paper towel to extend the service life of the ultrasonic cleaning machine;
Some of the key parameters we need to focus on are:
1 small ultrasonic cleaning machine frequency is the highest frequency of about 40KHz. 40KHz frequency noise, strong penetration, strong ultrasonic directivity, suitable for fine objects cleaning.
2 the higher the power density of power ultrasound, the stronger the cavitation effect, the faster the speed, the better the cleaning effect. Household small ultrasonic cleaning machine output power of 20W-40W.
3 the best effect of ultrasonic cavitation is 30 ° C-40 ° C at cleaning temperature. The higher the temperature of the cleaning agent, the more obvious the effect. Small household ultrasonic cleaning machines usually do not have a heating function. If a cleaning agent is added for cleaning, room temperature cleaning is completely acceptable.
At present, there are many small household ultrasonic cleaning machines, good grooves are 304 stainless steel, easy to clean anti-corrosion, and appearance simple and durable.
