Description

Acid oxidation potential sterilized water of a kind of low-corrosiveness and preparation method thereof

Technical field

The present invention relates to the sterilizing field, particularly acid oxidation potential sterilized 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, because the microorganism of the most of kinds of occurring in nature lives in the environment of pH 4-9, and the pH value of acidic oxidized electric potential water can affect 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 reach the purpose of killing microorganisms.

Secondly, because the distributions inside and outside microbial biofilm such as hydrogen ion, potassium ion, sodium ion are different, so that the inside and outside current potential of film has certain potential difference when reaching dynamic equilibrium, generally be about-700～+ 900mV.The biomembrane of aerobic bacterium inside and outside potential difference be generally+200～+ 800mV, and the biomembrane of anaerobic bacteria inside and outside potential difference be generally-700～+ 200mV.The factors such as the oxidation in the acidic oxidized electric potential water, reduction material and pH make its ORP be higher than 1100mV, have exceeded the scope of microorganism.Having high ORP(is ORP〉1100mV) EOW contact microorganism after capture rapidly electronics, 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 cellular metabolism enzyme, make intracellular organic matter overflow, dissolve, thereby reach the purpose of quick killing microorganisms.

At last, available chlorine can make the permeability of cell change, or biomembrane generation mechanicalness is broken, and impels the cell Dissolve things inside outwards to ooze out, and causes bacterium dead.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 bacterium dead, thereby reaches the purpose of killing microorganisms.

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 higher, the pH value is lower, ORP is higher, the system synthesis sterilization effect is just better.

Embodiment

Below describe the present invention.

At present, the acid oxidation potential sterilized 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 its corrosive research on 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, and substantially without corrosion or mild corrosion, to heavy corrosion, its conclusion otherness is very large to carbon steel, copper, aluminium moderate to stainless steel.

Acidic oxidized electric potential water mainly is that three aspect factor causes to corrosion of metal, the one, and the acidity of system, the replacing hydrogen reaction of hydrogen ion and active metal (iron, magnesium, zinc etc.); The 2nd, the oxidisability of system (available chlorine); The 3rd, the impact of other ion in the system.But acid and oxidisability is the physics and chemistry speciality of acidic oxidized electric potential water, also is the decisive factor of bactericidal property, and therefore, in a sense, bactericidal property and corrosion of metal are the paradox of coexistence.

Compare with electrolysis, chemical method prepares acid oxidation potential solution, and by calculating the constituent content that can control in the solution, the Material Source of its A, B unit is wider general.But also caused the source of the impurity of introducing in the solution more complicated.

Discuss in the present invention bivalent cupric ion in the acidic oxidation environment to copper corrosion.

Chemical method prepares acid oxidation potential solution, and the introducing of bivalent cupric ion mainly contains three kinds of approach in the system, and one itself contains in the acid-base modifier or produces bivalent cupric ion, such as copper chloride or copper sulphate or Kocide SD etc.; Its two, use and carry cupric impurity in the raw material secretly; Its three, the component of other effects of cupric is such as thickener, stabilizing agent, hardening agent etc.

Bivalent cupric ion is undertaken by following basic mode copper corrosion,

Cu ²⁺＋Cu＝2Cu ^- ——1

Cu ^-＋[O]＝Cu ²⁺ ——2

In normal temperature, neutrality and non-oxidizable solution, the reaction 2 be slowly, the corrosive effect that above-mentioned serial reaction can be understood as simple bivalent cupric ion depends on the initial content (reaction 1) of bivalent cupric ion, and when bivalent cupric ion ran out, corrosion process finished.When the content of bivalent cupric ion was relatively stable, its corrosive effect changed little, and perhaps the corrosive effect that slowly carries out along with reaction 2 slowly strengthens.

In acidic oxidized electric potential water, the environment of the introducing of available chlorine and low pH, accelerated to react 2 carrying out, promoted the direct product univalent copper ion of metal and bivalent cupric ion again to change bivalent cupric ion into, reduced the reduction of bivalent cupric ion, thereby make the content of bivalent cupric ion in the system in to the process of copper corrosion, continue to increase state, and then aggravated reaction 1 and carried out.

As from the foregoing, contain the acidic oxidized electric potential water of bivalent cupric ion, bivalent cupric ion and hydrogen ion and available chlorine interact, and the system that affected greatly is to corrosion of metal.

See also Fig. 1, show among the figure: in the acid system, the increase of bivalent cupric ion content has strengthened system to corrosion of metal.Simultaneously as can be known, the synergy of hydrogen ion and bivalent cupric ion has strengthened system to corrosion of metal.

See also Fig. 2, show among the figure: in the system of acidic oxidation (containing ACC), bivalent cupric ion and available chlorine synergy, the system that affected greatly makes system to corrosion of metal generation hop to corrosion of metal.Wherein, different available chlorine content (3-5000ppm), the increase of bivalent cupric ion concentration (＞2000ppm), all can produce the hop to corrosion of metal.Simultaneously as can be known, the reduction of available chlorine makes system to the corrosion of metal reduction, and has reduced the significance of hop.

See also Fig. 3, show among the figure: in the system of acidic oxidation (containing ACC), different sour environment (pH2-7), the increase of bivalent cupric ion concentration (＞2000ppm), all can produce the hop to corrosion of metal.Simultaneously as can be known, acid reduction makes system to the corrosion of metal reduction, and has reduced the significance of hop.

Comparison diagram 1-Fig. 3 as can be known, the metal protection of acid oxidation potential sterilized water can be controlled or reduce to control bivalent cupric ion content at 3-5000ppm, at 0-2000ppm and available chlorine content.

We know that free chlorine or its derivative can strengthen oxidisability and the bactericidal property of system.The A unit is added the B unit, can reduce to a certain extent the oxidisability of mixed liquor, reduced simultaneously the risk of the safety of the free chlorine band of gas.Therefore, preferentially take the A unit is added the addition manner of B unit.As shown in Figure 4, the hybrid mode by control A, B unit adds the B unit with the A unit, can to a certain degree reduce corrosion of metal.The A unit is added the B unit, can take disposable adding or add in batches or slowly add or spray to add or the dropping mode.
