Description

Oxidizing potential sterilization water of a kind of low-corrosiveness and preparation method thereof

Technical field

The present invention relates to the sterilizing field, particularly oxidizing potential sterilization water of a kind of low-corrosiveness and preparation method thereof.

Background technology

The concept of introducing redox potential in the sterilization field is to come from the acidic oxidized electric potential water generation machine of Japanese 20th century development and production eighties and the acidic oxidized electric potential water that is produced by the generation machine.Acidic oxidized electric potential water (is called for short: the water of EOW) refer to have high redox potential (ORP), low pH value characteristic and low concentration available chlorine (ACC).

The mechanism of acidic oxidized electric potential water sterilization is as follows:

At first, the microorganism of the most of kinds of occurring in nature lives in the environment of pH4-9, and the pH value of acidic oxidized electric potential water can influence electric charge on the microbial biofilm and the absorption of nutriment, the activity of enzyme, and the toxicity of giving property or harmful substance of nutriment in the change environment, thereby killing microorganisms fast.

Secondly, because the distribution differences inside and outside microbial biofilm such as hydrogen ion, potassium ion, sodium ion make the inside and outside current potential of film that certain potential difference be arranged when reaching dynamic equilibrium, generally be about-700～+ 900mV.Factors such as the oxidation in the acidic oxidized electric potential water, reduction material and pH, making it have high ORP(is ORP〉1100mV).Capture electronics rapidly behind the EOW contact microorganism, disturb the biomembrane balance, change biological transmembrane potential difference, the inside and outside osmotic pressure of film, the destruction that causes the enhancing of biomembrane permeability, cellular swelling and biological metabolism enzyme, make the interior material of film overflow, dissolve, thus quick killing microorganisms.

At last, available chlorine can make the permeability of cell change, or biomembrane generation mechanicalness is broken, and impels the interior material of film outwards to ooze out, and causes microbial death.And hypochlorous acid is neutral small-molecule substance, easily invades in the cell with protein generation oxidation or destroys its phosphate dehydrogenase, makes the glycometabolism imbalance cause microbial death, thus killing microorganisms fast.

The sterilizing ability of EOW system is to take as the leading factor with ACC, and low pH value and high ORP are the synergistic result of three of important promotion.This systematic collaboration effect far above single ACC, low pH value and high ORP effect simply add and, its ACC is more high, the pH value is more low, ORP is more high, the system synthesis sterilization effect is more good.

Embodiment

Below describe the present invention.

Known at present, available chlorine has three kinds of basic existence forms, comprises chlorine, hypochlorous acid molecule and hypochlorite ion, and wherein chlorine and the bactericidal property of hypochlorous acid molecule in solution are far longer than the hypochlorite ion.Because the hypochlorite ion needs slow hydrolysis, change the hypochlorous acid molecular conformation into after, just have microbe killing properties can, so control the pH value of available chlorine solution, available chlorine is existed with the form of hypochlorous acid molecule and chlorine, can guarantee bactericidal property.

Hypochlorous ionized acidic constant is approximately pKa=7.6, so during the pH value＜pKa (7.6) of available chlorine solution, the ratio of molecule-type available chlorine is greater than ionic available chlorine in the available chlorine of solution.The activity of q.s (＞30%) molecule-type available chlorine can be brought into play in pH value≤8.0 of available chlorine solution o'clock.PH value 〉=9.0 of available chlorine solution o'clock, the ratio less than 4% of molecule-type available chlorine.

At present, acid oxidation potential sterilization water has launched Primary Study to corrosion of metal, and the result who has announced shows that acidic oxidized electric potential water has general metal protection.But the research to its corrosive mechanism is not carried out, and its corrosivity is considered to usually that peracid acidity (pH2-3) causes, even thinks that nearly neutral electrolyzed oxidizing water can avoid metal protection.The result who has announced shows acidic oxidized electric potential water, stainless steel is not had substantially corrodes to mild corrosion, to carbon steel, copper, aluminium moderate to heavy corrosion, its conclusion widely different.

Electrolyzed oxidizing water is because oxidisability and hydrionic comprehensive effect cause to the generality of metal erosion, metal has the trend that forms oxide in electrolyzed oxidizing water (pH/ACC), oxide has the trend that is converted into water soluble ion under the hydrogen ion effect, thereby finish by the transformation of metal simple-substance to the water-soluble metal ion, macro manifestations is that metal generally is corroded.

The formation of oxide has two-way function, can change water soluble ion into, causes corrosion, can stop simultaneously contacting of corrosion factor and metal inside, corrodes thereby stop further; Free hydrionic concentration affects the oxidisability of available chlorine, influenced the dissolution velocity (as shown in Equation 1) of oxidative horizon simultaneously.The generation of oxidative horizon forms dynamic balance with dissolving, and macro manifestations is that metal is corroded with given pace.

And pH and oxidisability are the physics and chemistry speciality of electrolyzed oxidizing water, also are the decisive factors of bactericidal property, and therefore, on certain meaning, bactericidal property and metal protection are the paradox of coexistence.

When having polynary weak acid in the solution, produced the balance of weak acid molecule, its hydrogen radical ion and acid ion thereof, the unionized hydrogen in the solution (weak acid molecule and hydrogen radical ion thereof) has the ability (shown in 2,3) of dissolution of metals oxidative horizon equally.The generation of hydrogen radical ion, acid ion (aggressivity anion) in the solution, under diffusion or electric field or oxidation, be adsorbed on passivating film surface or enter in the film by the aperture in the passivating film or defective, changed the structure of passivating film, promoted the dissolving of passivating film, accelerated metal inside further corrosion takes place.Macro manifestations is that the existence of polynary weak acid, its hydrogen radical ion and acid ion thereof makes the corrosion of metal aggravation.Wherein the factor of corrosion aggravation is based on the influence of unionized hydrogen in low pH environment, and along with the increase of pH, ionization aggravates, and acid ion increases, and the factor that corrosion is accelerated accounts for the master with the influence that anion corrodes.

H ₂A+CuO=Cu ²⁺+ A ^2-+ H ₂O formula 2

2HA ^-+ CuO=Cu ²⁺+ 2A ^2-+ H ₂O formula 3

Compare with electrolysis, chemical method prepares oxidizing potential solution, and by calculating the constituent content can control in the solution, its pH value regulon, that available chlorine provides the material of unit to originate is wider general.But also caused the source of the impurity of introducing in the solution more complicated.

Discuss fumaric acid (H in the present invention ₂A) and corresponding acid ion (HA ^-/ A ^2-) between pH=2-8 in the oxidative environment to corrosion of metal.Because copper and simple hydrogen ion do not react, thus with copper as research object, can more effectively embody pH/ACC/[H ₂A/HA ^-/ A ^2-] comprehensive corrosive effect.With [H ₂A/HA ^-/ A ^2-] the content sum of expression fumaric acid, fumaric acid hydrogen radical ion, fumaric acid radical ion, H ₂A/HA ^-/ A ^2-The amount of substance sum of expression fumaric acid, fumaric acid hydrogen radical ion, fumaric acid radical ion.

In the oxidizing potential sterilization system, fumaric acid (H ₂A) and corresponding acid ion (HA ^-/ A ^2-) introducing mainly contain four kinds of approach, one, the raw material employing itself contains or can produce H ₂A/HA ^-/ A ^2-Material, as fumaric acid, fumaric acid sodium; Its two, raw material adopts H ₂A/HA ^-/ A ^2-Precursor substance, described precursor substance refers to can change H in the oxidizing potential sterilization water of pH2-8 ₂A/HA ^-/ A ^2-Material, as fumaryl chloride; Its three, use to carry secretly in the raw material and contain H ₂A/HA ^-/ A ^2-Or the impurity of its precursor substance; Its four, contain H ₂A/HA ^-/ A ^2-Perhaps can be converted into H ₂A/HA ^-/ A ^2-The component of other effects, as thickener, stabilizing agent, hardening agent, desiccant, pH buffer, chelating agent etc.

See also Fig. 1, Fig. 2, show among the figure: in the system of pH=2,8 oxidisability (containing ACC), fumaric acid, fumaric acid hydrogen radical ion, fumaric acid radical ion and available chlorine synergy, the system that influenced makes system produce hop to corrosion of metal to corrosion of metal.Be in the system of pH=2.0 or 8.0, the available chlorine of variable concentrations (〉=3ppm) with [H ₂A/HA ^-/ A ^2-] (＞1.8M) collaborative, the hop that all can produce metal protection.Simultaneously as can be known, available chlorine reduces, and the metal protection of system is reduced, and reduced the significance of hop.

See also Fig. 3, Fig. 4, show among the figure: in the system of pH=2-8 oxidisability (containing ACC), fumaric acid, fumaric acid hydrogen radical ion, fumaric acid radical ion and hydrogen ion synergy, the system that influenced makes system to corrosion of metal generation hop to corrosion of metal.That is, contain available chlorine system (〉=3ppm), pH between 2-8, [H ₂A/HA ^-/ A ^2-During]＞1.8M, all can produce the hop to corrosion of metal.Simultaneously as can be known, acid reduction reduces the metal protection of system, and has reduced the significance of hop.Simultaneously as can be known, acid reduction has promoted H ₂A-HA ^--A ^2-Conversion, the intensity of the accelerated factor of corrosion reduced, increased the required concentration of hop (＞1.8M).

Comparison diagram 1-Fig. 4 controls [H as can be known ₂A/HA ^-/ A ^2-]≤1.8M can control or reduce the metal protection of oxidizing potential sterilization water.

Because described fumaric acid is binary weak acid, hydrionic ionization not exclusively or the partial hydrolysis of acid ion can produce different buffer systems, has antitypy more for keeping of system acid-base value, when the pH of system in the scope of pKa ± 1, have the maximum cushioning ability.Be shown below:

H ₂A<==>H ⁺+HA ^- （pKa1=3.03）

Ka1=[H ⁺]*[HA ^-]/[H ₂A] ---------(1)

HA ^-<==>H ⁺+A ^2- （pKa2=4.44）

Ka2=[H ⁺]*[A ^2-]/[HA ^-] ---------(2)

As from the foregoing, as shown in table 1:

1, in the pH2-8 environment, add fumaric acid or its monovalent salt or its divalent salts, or add above-mentioned three's arbitrary composition, its composition all can change H into ₂A/HA ^-/ A ^2-Composition;

2, in the pH2-8 environment, H ₂A/HA ^-/ A ^2-Ratio depend on the pH value;

3, when specific pH, [H ₂A/HA ^-/ A ^2-] addition increase, wherein the absolute content of each component increases, and relative scale is constant.
