Description
Technical field
The present invention relates to being filled with technology and device of the hydrogen to over-saturation state in liquid more particularly to a kind of super
The preparation facilities of saturation nano bubble hydrogen solution.
Background technology
Hydrogen solution refers to that hydrogen is dissolved in the gas-liquid mixture formed after water, adds hydrogen not change the pH value of raw water.
From 2007《It is natural》Japanese Ohta Shigeo of magazine publication etc. has anti-oxidant, anti-inflammatory, anti-apoptotic biological on hydrogen
Medical effect is reported.Over 7 years, the biological effect of the hydrogen aqueous solution is gradually received and is approved by people.Hydrogen
Solution makes common people rouse oneself ground, reverse the effect and extremely of pathology damage on one's own initiative because having high biological safety
It is convenient to use mode (such as：Drink/soak), most merited attention as medical care market in world wide already
One of project.Wherein, over-saturation hydrogen solution is high because of preparation difficulty and has a wide range of application, and biological medical effect is particularly
Significantly.
Current most widely used method by drinking hydrogen water intake hydrogen, be also hydrogen health-oriented products it is most safe,
Most common form.It is a kind of even water insoluble gas of indissoluble but solubility of the hydrogen in water is very low,
Under normal temperature and pressure (normal temperature be 20 DEG C, normal pressure is 101.3Kpa), the hydrogen saturation meltage of 1L water for 18.2ml or
1.6mg, usual we are represented with mass concentration 1.6ppm, in view of hydrogen is difficult to be dissolved in the characteristic of water, become people
The aqueous solution by drinking hydrogen content high obstacle.
Drink the preparation method of hydrogen water and dissolve the types such as water, magnesium metal reaction water including electrolysis water, hydrogen.

The chlorine residue of generation and ozone, the pH value of water will change, and the metal electrode of electrolytic cell directly acts on water, meeting
There is micro metal ion to separate out, if for drinking, metal ion can enter in human body with water, more important point
It is that aqueous solution of hydrogen efficiency that electrolysis water mode is obtained is very low and solubility is low, hydrogen in aqueous full is not reached far
And state.
Produce the chemical reaction of hydrogen and hydroxide at normal temperatures using metal and water, it is also possible to prepare hydrogen water.
Many metals such as iron, aluminium, magnesium etc. can produce hydrogen with water reaction, but most metals have poor taste, reaction
Speed is slow, the shortcoming of overt toxicity.
