Abstract

According to the invention, a sulfur-doped porous Ni-La/foam metal material is used as a cathode, an inert metal material is used as an anode, an electrolytic cell is divided into an anode chamber, amiddle chamber and a cathode chamber through an ion exchange membrane, a mixed solution of potassium carbonate, potassium bicarbonate and purified water is introduced into the middle chamber, water ispurified into the cathode chamber and the anode chamber, and the power supply is powered on to electrolyze to obtain the bactericide, wherein the pH value of the bactericide is equal to 12.5 +/-0.3,no surfactant, preservative or other additive is added, the main components are purified water and trace mineral elements, and the cleaning effect of the bactericide is greater than 99.9%.

Description

technical field [0001] The invention relates to a preparation method of a superalkaline bactericide, which belongs to the field of electrolyzing water to prepare superalkaline ionized water, which is used in the field of bactericides, disinfectants and cleaning agents. Background technique [0002] At present, the disposable antibacterial hand sanitizers on the market are based on various chemically synthesized surfactants. In order to make them have antibacterial functions, various bactericides are added. In order to avoid the damage of various agents to the skin, there are also Different skin care agents will be added, but although these products have a certain decontamination ability, they are relatively sticky after use, and the experience is not strong, and the hazards of the surfactants contained in the products have been widely concerned in recent years. The focus is mainly on the irritation to the mucous membrane, sensitization to the skin, toxicity, heredity, carcin...
