1.Preface

Functional water is that regenerative solution is generated by scientific measure.the proceeding course and function of solution has obvious scientific basis.the strong acidic electrolyzed water and strong alkaline electrolyzed water are correspondent with this definition of material.

Strong acidic water with strong disinfect effect,as the cleaning detergent in medical,food and agriculture circle has extensive application.although the electrolyzed water with disinfect effect includes strong acidic water and soon,the strong acidic water (1)it can accumulate data in accordance with science(2)it has been approved by japan to use on the disinfect of washing hands and endoscopy cleaning.(3)it has been approved by Japan to use in the food additive.(4)it maybe has other function except disinfect.so,it is expected for medical industry in the furture.

This article will clarify the application of strong acidic water in medical dialysis,especially in the disinfect of dialysis tubing.

2.the application of strong acidic water in the disinfecting and cleaning of the dialysis machine

Strong acidic water as the new type detergent in contrast with the traditional has many properties.so many people worried that it will cause bad effect for material of device during the water using on the dialysis machine.here are the discussion about these worries.

3.The spare parts of dialysis machine once touch fluid,no matter which company,on the phase of corrosion,it can appear rust and melt.here is the reverse phenomenon in gas zone section and fluid second in the function of between SUS316 stainless steel of device and electrolyzed water and sodium hypochlorite.someone finds that the weight of electrolyzed water in gas section obviously change to see the rust,non is in the fluid section.in other hand,the report shows that the weight of sodium hypochlorite in gas section is not obvious change,but in fluid section is change.

Moreover,in order to inspect the impact of non metal for electrolyzed water,we use polyether sulphone,chlorinated resin,silicon and rubber as experimental material to evaluate the state of electron on the surface of material.the electronic spectroscopy measures the oxidizing and chlorine-absorbing level with the inspected object alike oxygen,carbon and chlorine.after the proportion of all electrons of experimental material in contrast with new type,it shows that the proportion of oxygen electron and chlorine electron has been increased without any problem of corrosion.

Someone pointed the report according to the experiment that the metal material can make buoy malfunction and make silicon tube leak and make impact with solenoid valve and silicon material.

The silicon tube and soft tube appear the phenomenon of hardening and cloudiness and breakage in term of long using time.we have found the rust mark beside vent in the cell.some rubber product appear the phenomenon of swelling and dissolving.the silicon appear the cloudiness.some resins has the phenomenon of slight cloudiness and rough surface.

In the impact of chlorine in order to resolve the metal material in gas section,teflon is used and the gas section is sealed.someone report that the outside of metal is clothed with transparent tube to resolve the silicon problem which can resist the corrosion.other material of spare parts can be change to resolve.

4.the suggestion of the application of strong acidic water in the disinfecting and cleaning of the dialysis machine

According to the over measures,the corrosion is basically resolved,but the strong acidic water has different corrosion function in contrast with traditional detergent,there needs more notice on the reserve of instrument.in order to develop and popularize the application of electrolyzed water on the dialysis machine,we should has the necessary to make the guide of strong acidic electrolyzed water.here are the declare of basic programs.

(1)property and state:in order to refrain from the generation of chlorine in electrolyzed water and reduction of impairing material,we suggest the property and state of electrolyzed water is on PH value 2.7 and effective chlorine 20mg/l.it is effective for this concentration of effective chlorine.

(2)Using method:the strong acidic water has the more rapid disinfect property in contrast with the traditional detergent.each disinfect time is 20-30 minutes in consideration with the length of tube.the electrolyzed water could not be reserved in tube in place of under running water.the residue of electrolyzed water is little,so it can curtail the cleaning time.if the electrolyzed water is cleand in pre-washing,it will reach best disinfect effect.

(3)Carbonate precipitation in tube:because the electrolyzed water has certain dissolved function for Ca and Mg,it can be solely used for a long time without simultaneous pickling.but some materials alike carbonate will be precipitated during dialysis in safeness with pickling 1-2 time a month.

(4)Protein attached with tube:here is the problem that the leaked protein is in tube,as appear in 5 hospitals.we take sodium hypochlorite to remove protein out twice a month.moreover,as is that electrolyzed water can remove protein in tube.blow is the notice during selection of removing protein:sodium hypochlorite is traditional which has the facile property.strong acidic water and strong alkaline water need the same level reserve cell to ensure the enough room.the manipulation of changing electrolyzed water is more complicate ad intricate,but the effect of electrolyzed water is good.

(5)Treatment and atmosphere:the electrolyzed water is safer and simpler manipulation than the traditional detergent.because the fan in the room,the chlorine can be resolved without any pollution for discharge and atmosphere.

5.the possibility and theme of electrolyzed water

Strong acidic water is strong disinfect detergent which is safer,lower concentration,;ess harmful pollution and less residue than the traditional detergent.in the other hand,if it is exposed upon the air,the activate HCLO can discharge chlorine in electrolyzed water leading to the lower disinfect effect.to be avoid,the electrolyzed water is reserved in close space(i month or so)it is not necessary to reserve long time because of low cost and high productive volume.

From report that the concentration of chlorine is dependent with the temperature.especially the ACC even more will be higher over 30 degree temperature.people know that the property of running water can be impacted by resource and season,we can take distill water place of running water to make it stable.

The electrolyzed water is non-irritated,transparent detergent with a little chlorine odor which needs inspection frequently.hereby,we must assign responsible who know about the electrolyzed water and maintenance knowledge and employer training.

6.Conclusion

Strong acidic water is unprecedented,strong disinfect and safe detergent.it is differently treated with other detergent.the disinfect mechanism is explained by science and it can be popularized in medical circle.the strong acidic water is less impact for human and atmosphere to let society happy.
