FOUNDATION

摘要

PURPOSE:To provide a foundation suitable for tissue paper that is able to hold OH- free radical with fungistatic action in a stable condition for a long time by infiltrating a certain amount of acid water containing OH- free radical and by covering the foundation with a shade film. CONSTITUTION:A certain amount of acidic water containing OH- free radical is infiltrated and a shade film covers the acid water. In OH- free radical, a dilute electrolytic solution of sodium chloride or potassium chloride is electrolyzed and a strong-acidic substance is created at the cathode. A shade film is used to prevent the OH- free radical from photochemical decomposition by shielding from ultraviolet light to visible light. The shade film is made of a laminated film which is composed of aluminum foil and resin film or made of a resin film vapor-deposited with aluminum, or both of these methods are applied.
