Negative-potential acid water and preparation method thereof

Abstract

The invention provides negative-potential acid water and a preparation method thereof, which belong to a technology for purifying the water quality and concretely relate to the field of functional water, in particular to a technology for changing and finishing a water molecule group structure. The invention has the characteristic that the water is acid and has a negative potential. The negative-potential acid water is manufactured according to the following operation sequences of: setting a main water tank and an auxiliary water tank, separating the main water tank and the auxiliary water tank by an ion diaphragm and adding raw water; electrolyzing in an electrode inversion way; measuring pH value and ORP value alternately; once the pH of the raw water of the main water tank is smaller than 8.5 and the oxidation-reduction potential ORP is smaller than -300mv, pausing electrolysis and changing the setting of electrodes; setting the electrode of the main water tank into an electrolytic positive pole, setting the electrode of the auxiliary water tank into an electrolytic negative pole and executing re-electrolysis; and obtaining the negative-potential acid water until the pH value is measured to be smaller than 6.5 and the ORP is measured to be smaller than 0. The invention has the following advantages: the negative-potential acid water is provided for the market, the invention has a certain anti-oxidation capability, and the senility of the skin is delayed; a device for preparing the negative-potential acid functional water is also arranged, the preparation is easy, and the cost is low; and novel practical water is provided for the market.

Description

technical field [0001] It belongs to the water purification technology, to be precise, it involves the field of functional water, especially the technology of changing and arranging the structure of water molecular groups and changing the oxidation-reduction potential of water. Background technique [0002] With the improvement of social living standards, people have put forward higher requirements for domestic water, including drinking water and washing water. As the best choice to comprehensively improve the water level and function, electrolyzed water equipment has begun to be effectively marketed and applied in recent years. The electrolytic water equipment directly generates two kinds of water after tap water or purified water is electrolyzed: one is alkaline negative potential water that can be directly drunk and has certain health care and therapeutic effects, and the other has bactericidal and cosmetic effects positively charged acidic water.

Problems solved by technology

However, at present, whether the electrolyzed water machines at home and abroad are continuous or tank-type, they can only generate positive-potential acidic water, and positive-potential acidic water has strong oxidative properties, and long-term use may have certain damage to skin surface cells.
