Microenvironmental gas permeable layer capable of supplying hydrogen

Abstract

A gas permeable layer capable of supplying hydrogen includes a thin layer, encapsulating a hydrogen production formula. An outer side of the thin layer is airtight. An inner side is air-permeable. An inner side surface has a plurality of small holes. The thin layer can be a single layer or a composite layer. The hydrogen production formula does not dissipate. The hydrogen production formula absorbs moisture in the air or liquid water, thereby generating hydrogen. The hydrogen is released onto the skin and into the human body through the small holes. The hydrogen production formula includes metal peroxides, metal hydroxides, or metal hydrides and aluminum powder, or microsilica. The gas permeable layer can be used in sanitary products including eye masks, mouth masks, face masks, cosmetic facial masks, bras, pasties, nursing pads, sanitary napkins (towels), diapers, panty liners, wound dressing, woundplasts, bandage gauze, decubitus pads.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) The present invention is exemplified by the following embodiments, but the present invention is not limited by the following embodiments. The following describes the features, applications and advantages of a gas permeable layer capable of supplying hydrogen of the present invention. Nevertheless, any equivalent implementations or modifications without departing from the technical spirit of the present invention are intended to be included in the scope of the appended claims.

(9) As shown in FIG. 1 to FIG. 3, the present invention provides a gas permeable layer 1, comprising: a thin layer 11 encapsulating a hydrogen production formula, wherein an outer side of the thin layer 11 is airtight and an inner side of the thin layer 11 is air-permeable, an inner side surface has a plurality of small holes 111, and the thin layer 11 can be a single layer or a composite layer; and a hydrogen production formula 12, encapsulated in the thin layer 11, does not dissipate, absorbs moisture in the air or liquid water, thereby generating hydrogen. It can be seen in FIG. 2 that, through the small holes 111, the hydrogen is absorbed into the human body through skin, nostrils, mouth cavity, eyes, and other parts of the human body in contact with.

(10) In the present invention, the hydrogen production formula 12 is encapsulated by the thin layer 11 with the outer side, which is airtight, and the inner side, which is air-permeable. The hole diameter of the small holes 111 of the inner side of the thin layer 11 is smaller than the diameter of the hydrogen production formula 12 to ensure that the hydrogen production formula 12 does not leak. The outer side of the thin layer 11 is an airtight material, and the inner side of the thin layer 11 is a skin-friendly material.

(11) When being stored, the gas permeable layer 1 is packaged with an airtight material to ensure that moisture in the air does not react with the hydrogen production formula 12 in advance; when being used, the airtight package is torn off and applied at a desired position. By using the gas permeable layer 1, sweat and moisture can be retained from leaking through the airtight material of the outer side, so that the hydrogen production formulation 12 can react sufficiently with water and supply hydrogen to the skin.

(12) A material of the inner side of the thin layer 11 for encapsulating the hydrogen production formula 12 can be a silica gel, a silicone rubber, a non-woven fabric, or a plastic gas permeable membrane. A material of the outer side of the thin layer 11 can be a polypropylene, polyethylene plastic film, an aluminum film, or a composite film.

(13) The hydrogen production formula 12 can be in the form of powder or granules comprising metal peroxides, metal hydroxides, or metal hydrides and aluminum powder, or microsilica.

(14) Wherein the metal peroxides are selected from a group consisting of calcium peroxides, magnesium peroxides, sodium peroxides, and potassium peroxides; and the metal hydroxides are selected from a group consisting of calcium hydroxides, magnesium hydroxides, sodium hydroxides, and potassium hydroxides.

(15) The hydrogen production formula can also comprise compounds that can form metal hydroxides through moisture, such as magnesium hydrides, calcium hydrides, and silicon hydrides.

(16) Optionally, the hydrogen production formula can be added with a solid acid that neutralizes the hydrogen production formula, so that the pH value is between 4-9 in order to avoid irritating the skin and enhance the hydrogen absorption effect. The solid acid is selected from a group composed of solid citric acid, solid lactic acid, solid oxalic acid, solid hydrochloric acid, solid phytic acid and solid silicic acid.

(17) The following reaction provides a mechanism of the hydrogen production formula for supplying hydrogen:

(18) In the case of peroxides, it will first react with water to form hydroxides and release oxygen, the reaction formula is:
2XO.sub.2+2H.sub.2O.fwdarw.2X(OH).sub.2+O.sub.2(X is calcium, magnesium) or
2Y.sub.2O.sub.2+2H.sub.2O.fwdarw.4Y(OH)+O.sub.2(Y is sodium, potassium)

(19) Hydroxides react with the aluminum powder to form hydrogen, referring to the following reaction formulas:
2Al+2H.sub.2O+X(OH).sub.2=X(AlO.sub.2).sub.2+3H.sub.2
2Al+2H.sub.2O+2Y(OH)=2YAlO.sub.2+3H.sub.2

(20) Metal hydrides react with moisture to form hydrogen and metal hydroxides, and metal hydroxides are then reacted with water to produce hydrogen continuously.

(21) In the aforementioned reactions, if a relatively large amount of hydrogen is to be rapidly formed, peroxides or hydroxides of an alkali metal (Group IA) (i.e. sodium or potassium) which is more active can be selected as reactants.

(22) Through the combined applications of the aforementioned exemplary hydrogen production formula, those skilled in the art can also associate with using silicon to react with hydroxides and water to generate hydrogen, which is an equivalent implementation of the combinations of the present invention and should be included in the scope of the appended claims of the hydrogen production formula of the present invention. The reaction formulas are as follows:
Si+4H.sub.2O=H.sub.4SiO.sub.4+2H.sub.2
H.sub.4SiO.sub.4+2NaOH=Na2SiO.sub.3+3H.sub.2

(23) In order to clarify the preferred dosage ratio, therefore, the hydrogen generation efficiency of each reactant in the range of 0.01-100 g is tested respectively. The hydrogen production formula can react to produce hydrogen when a weight ratio of metal peroxides or metal hydroxides:aluminum powder=1:100-100:1, and has the best hydrogen generation efficiency when the weight ratio is 1:10-10:1.
