In 1982, Matsuo, Japan, began to study strongly acidic water. In 1989, Tokyo established the "Water Design Research Association", and soon Osaka also established the "Water Science Research Association" with more than 600 member companies and published the "Sterilization of Acidic Water" "Effect", "Prevention of Bedsores in the Elderly" and other reports on acidic water. Recently, national or quasi-national research institutions such as the "Functional Water Research Institute" and "Life Water Research Institute" have been established: 
① The "Functional Water Research and Development Subcommittee" lasted 4 years from 1990 to 1993, and its published research The report included "the mechanism of action of electrolyzed water", "the effect of functional water on cell culture", "the effect of electromagnetic fields and electrolyzed water", etc.;
② In 1993, the "functional water research and promotion consortium" under the jurisdiction of the Ministry of Health and Welfare of Japan established about 500 million days Yuan’s Fund focuses on the application of strong acidic water in the fields of medicine and dentistry. Two seminars were held in 1994 and 1995;
③ In 1994, the “Functional Water Research Institute” was funded by the Special Industrial Technology Promotion Organization of the Department of Agriculture and Forestry of the Ministry of Agriculture and Forestry.
④ In 1994, the Spring Conference of the Chemical Society of Japan first focused on water, and there was a grand occasion that the number of participants exceeded the scheduled number and the venue had to be changed;
⑤ In June 1995, a seminar on "How to Utilize the Function of Electrolyzed Water in Agriculture" was hosted by the New Agriculture and Forestry Co. Yes. 21 Manufacturing principle Water electrolysis is made by adding a small amount of salt to tap water and separating the anode and cathode with a diaphragm. Special electrodes are used to apply high voltage to the water to electrolyze the water. At this time, the anode The following oxidation reaction and reduction reaction occur respectively with the cathode to generate strong acidic water and strong alkaline water.
The physical and chemical properties of strong acidic water are as follows: usually the pH is between 2.0 and 3.5, and it has a high redox potential, reaching 1000m v to 1200m v; dissolved oxygen is 10ppm to 50ppm; strong oxidizing power; storage: 1 month in a closed container , 3 days in an open container, the concentration of active chlorine decreases after ultraviolet radiation; the sterilization speed is quick-acting, but organic matter or after being neutralized is slow-acting.
The sterilization mechanism of strongly acidic water is generally considered to be low pH and high ORP (oxidation reduction potential). However, recent studies have shown that it is due to the combined effects of hypochlorous acid and the simultaneous production of chlorine, hydrogen peroxide, OH, etc., which makes bacteria necessary for survival. The cell components are decomposed, denatured, and damaged.
① Strong bactericidal power, wide bactericidal spectrum Table 2 and Table 3 compare the bactericidal effects of strong acidic water with other drugs. It can be seen from the table that the strong acidic water starts to show the bactericidal effect after 5 seconds. Compared with other drugs, the bactericidal spectrum is wide and the bactericidal effect is better.
② It is harmless to the human body. At present, some of the disinfectants on the market are mostly chemical substances, or they are carcinogenic, or are irritating to the skin, or have disadvantages such as bad smell.
Because the strong acidic water has a good sterilization effect and has an astringent effect, it can be used for disinfection in restaurants, hotels, and medical institutions. For example, it can be used for disinfection of:
① Using equipment, floors, walls, staff's hands, clothing, etc.;
② Yes Disinfection and sterilization of cells and pathogens that cause food poisoning;
③ Cleaning, sterilization and preservation of fresh food;
④ Prevention and treatment of plant diseases [2,3,7～12].
In addition, strong acidic water has been used in medical treatment, food processing, and plant diseases in recent years. Cultivation, lawn farming and other aspects are also being gradually promoted and applied. For example, the water is activated by strong acid water, which has good permeability, can activate cells and accelerate wound healing. It can be used for gangrene, pressure sores, burns, scalds, wound cleaning, dermatitis and infected sores. Treatment before skin grafting, etc.
It is said that Japan has begun to equip the National University Hospital with such a strong acidic water production device, and has promoted its use. [1]
Production Overview
Japan currently has 20 manufacturers producing strong acidic water manufacturing devices, such as Miura Electronics, Sanyo Electric, Asahi Glass Engineering Co., Ltd., Chiyoda Manufacturing Co., Ltd., etc. China Titanium Valley Baoji Aohai Titanium Industry Co., Ltd. has such prototypes as early as 2016 This type of device is an extension of the same kind of direct-use acid water machine.
