When it comes to bubbles, "bubbles in the sun, burst at the touch" is like a music box that is opened in an instant, and it begins to loop around the ear over and over again, and it can't stop.

"Fragile" seems to have become the exclusive label of bubbles, and it is not false that bubbles will burst, but you may have been deceived by the delicate appearance of bubbles.
"Better than one"
Bubbles are the best in line
"Water can carry a boat, but also can overturn the boat" the phrase must have heard the calluses in everyone's ears, but in real life, unless the boat leaks, how can the ship sink?
With the deepening of scientific research, people have found that the ship may really sink, and the culprit of this phenomenon may be the bubbles formed by a large amount of water vapor, methane and CO2 and other gases released by the submarine volcanoes and fissures, which will cause the sea surface to "open the pot" like boiling water, while causing the density of water to decrease, and the buoyancy of the passing ship is also greatly reduced, and it sinks into the seabed instantly.

Walking towards the depths of the ocean, the bubble of "one touch and one break" has become a more powerful weapon there - the pistol shrimp has two "clips", one large and one small, when catching prey, the large anchovy that pops out instantaneously can produce high-speed water flow, while stimulating many "cavitation bubbles", the bubble collapses instantaneously, the surrounding instantaneous water temperature can reach thousands of degrees, can produce more than 200 decibels of noise (much higher than the gunfire of 150 decibels), and the sound waves generated can even interfere with the sonar system of the warship. This is a low-pressure cavitation bubble, this huge energy "cavitation" can instantly stun the prey, becoming a pistol shrimp plate meal.

Bubble's superpowers
More than that
Although these bubbles are very powerful, they are in terms of the time of existence, and when they first appear, they will soon burst and disappear. Can you extend the life of the bubble a little longer? In fact, people's research on the "sustainability" of bubbles has been deepening.
Since 1950, there have been prediction theories about the relationship between bubble life and bubble radius; by 1994, the concept of micro-nano bubbles was formally proposed, and it was also used to explain the attraction between two objects... The "micro and nano bubbles" here are special bubbles that can be stable in water for minutes or even hours! They range in size from 1 nanometer to 50 microns, which is smaller than the diameter of a hair.

It was found that the possessive molecules bound to micro and nano bubbles have a specific affinity with tumor targets. Therefore, researchers have used micro and nano bubbles to produce nano-sized ultrasonic contrast agents, which have a wide range of application prospects in the early quantitative diagnosis and targeted treatment of tumors [1].
Micro and nano bubbles are not only smaller than ordinary bubbles, but also have some special properties that are different from ordinary bubbles. As mentioned above, micro and nano bubbles have an extra long presence time. This is because the ζ potential generated by the surface charge of the micro and nano bubbles is very high, so that the micro and nano bubbles in the solution have a repulsive resistance between the bubbles, so that the bubbles can maintain a certain distance, not only to avoid each other coalescence and rupture, but also to prevent the formation of larger bubbles, thereby promoting the stability of micro and nano bubbles [2].
Compared to ordinary sparkling water (left), water filled with micro and nano bubbles (sliding to the right) looks like milky white milk.
At the same time, the micro and nano bubbles are too small, so that the surface tension of the compression effect on the internal gas is more significant, in the process of slow rise, the specific surface area and internal air pressure are also infinitely increased, and finally the internal reaches a certain limit value when the rupture disappears, and a strong micro-blasting force is generated.

Since the 1980s, China's scientific expedition workers have successively excavated important shipwreck sites such as the "Nanhai No. 1" in Guangdong, and the excavated porcelain and other cultural relics have almost been unrecognizable under the corrosion of seawater and the attachment and condensation of aquatic organisms.
If scraped with a knife, it is easy to cause damage to hard surfaces, and chemical cleaning materials also have a more or less corrosive effect. The micro-nano bubbles with efficient interfacial activity and micro-blasting force have successfully attracted the attention of scientific expedition workers, and in the cleaning practice of "Nanhai No. 1", it has been proved that micro-nano bubbles are very effective in dealing with old scales, and the adhesive utensils can be successfully separated, and the details of the ornament can be perfectly preserved.

Before it is over, micro and nano bubbles can also carry out "magic" attacks - at the moment of rupture, due to the drastic changes in the disappearance of the gas-liquid interface, the high concentration of ions accumulated on the interface will release the accumulated chemical energy in an instant, which can stimulate a large number of hydroxyl radicals [5]. These hydroxyl radicals act like strong oxidants for walking, not only killing and inhibiting bacteria, but also degrading difficult organic pollutants such as phenol into inorganic substances.
And in order to achieve a better "curative effect", the current micro and nano bubbles will most of the time with ultraviolet or ozone together, strong and strong to play a role in the treatment of industrial wastewater, and the higher the initial concentration of pollutants, the better the degradation effect [6], is simply a super "washing spirit" in the industrial field.
The dimensionality reduction strike of cutting-edge technology
Specialize in life's problems
The tiny micro and nano bubbles seem inconspicuous, but they have extraordinary skills. In the video below, you can see how bubbles are produced in nature, and how bubbles are perfectly integrated into daily life by humans, even water heaters

The continuous development and progress of cutting-edge technology is also constantly being improved, and finally successfully used for civilian use. With a history of 101 years, Rinnai has been inspired by the many advantages of micro and nano bubbles, and has developed the latest Linnei BLU-X oxygen falcon water heater, which has successfully made micro-nano living oxygen bubbles, so that ordinary people can also feel the efficient charm brought by this tiny bubble.
What sparks can micro-nano living oxygen bubbles and water heaters collide? The most important thing, of course, is to make the bath more refreshing!
The diameter of human pores is 80-100 μm, while the ordinary water molecular mass is about 200-400 μm. The micro-nano activated oxygen bubbles produced by the Rinnei BLU-X oxygen falcon water heater have an average diameter of 50 μm, which is much smaller than the pore diameter. Think back to the current bathing — flushing, applying facial cleanser shower gel, rubbing casually, flushing, and then sloppily. According to the test report of an authoritative third party, the experimenters used water containing micro-nano living oxygen bubbles and ordinary water to test the oil content of the subjects' forehead skin, and found that the oil removal rate after cleaning by micro-nano living oxygen bubbles was as high as 88.8%. With Lin Nei's help, a simple flush every morning will make your skin clearer and more energetic.

Many people are very repulsive to bathing in winter, either because they feel good about themselves and think that they don't sweat much during the day, or because they have to apply body lotion all over the body after taking a bath, which is too troublesome. But in fact, with the Bruclay BLU-X oxygen falcon water heater, bathing in winter can also become a worry-free thing. The test report shows that after 15 minutes of bathing in the forest, the water content of the skin can be increased by about 7.5% (the difference between ordinary water and micro-nano active oxygen soaking water), maintaining better skin moisture, and the gloss and softness of the hair are also significantly increased.
In addition to the bathroom, micro-nano live oxygen bubbles can also be used in the kitchen sink. In the past, two brushes were made with hot water + dish soap, but the hydroxyl radicals (OH-) produced when the micro-nano active oxygen bubble burst helped to degrade pollutants such as oxidative oils and bacteria. Through the impact of countless active oxygen micro-bubble bursts instantaneously combined with a large number of hydroxyl radicals, it can efficiently eliminate harmful bacteria such as fruits and vegetables, E. coli on the surface of meat, Staphylococcus aureus, etc. The bacterial residue is clean in one rush, and the detection results show that the removal rate can be as high as 99%, and at the same time, the pesticide residue removal rate can be improved during fruit and vegetable cleaning, which is environmentally friendly and safe.

In the video, we used the micro-nano living oxygen bubble released by the forest to rinse a variety of vegetables and fruits, and even the ultimate challenge of walnuts was added, and found that the micro-nano living oxygen bubble was not afraid at all, and the cleaning effect was very significant!
So how did Lin Nei master and unlock the micro-nano living oxygen bubble black technology? In fact, the raw materials are only air and water, but the air accelerated by the nozzle valve is strongly crushed under the intelligent pressure of the gas-liquid mixing pump, and then the crushed bubbles are further compressed and dissolved through the breakthrough "degassing tank + automatic exhaust valve", and finally form a micro-nano active oxygen bubble with an average diameter of 50 μm, which is released strongly through special showers and faucets.
However, the Rinnei BLU-X oxygen falcon water heater is not only a bully who only understands professional knowledge, it is also a caring housekeeper who understands the user better. It has an exclusive "hot and cold punch" skill, through the alternating hot and cold massage of the body, coupled with thermostatic bath, pressurization system and other supporting technology, you can enjoy the comfort of professional SPA institutions every day at home.
After the network, the BLUE-X oxygen falcon water heater can also control the water temperature and various bathing modes on the mobile app, and the details of maintenance, failure and even gas consumption will also remind you in time
Seeing this, do you still feel that "bubbles" are so ordinary, so ordinary? In fact, the bubble itself is no different, but thanks to the combination of modern technology and technology, micro and nano bubbles have a more valuable "soul", but also for bathing, cleaning this day after day of life details add a rare sense of comfort. With the help of the Linnei BLU-X oxygen falcon water heater, it is easy to get away with it
