Problems solved by technology

Although the coated iron powder solves the pollution problem of the iron powder to the drug pack, "the coated iron powder (iron powder / composite electrolyte) has a structure in which the solid electrolyte can be directly attached to the iron powder", and does not contain Moisture, there will be no water film effect, it cannot activate the oxygen-absorbing iron powder, and it cannot create more favorable conditions for the oxygen absorption reaction and improve the oxygen absorption performance of the product

Embodiment Construction

[0053] The present invention will be specifically introduced below in conjunction with specific embodiments, emphatically introducing the situation of double-material packaging.

[0054] The finished medicament of the water film oxygen absorber includes treated iron powder and reactive base, and the weight ratio of the treated iron powder and reactive base is: 0.05-9:1; or according to the mass percentage of the treated iron powder and reactive base 90-99.5% and 0.5-10% respectively;

[0055] Another kind of water film oxygen absorber finished medicine can only deal with iron powder.

[0056] The treated iron powder is that the surface of the iron powder is covered with a water film layer containing medium and alkaline dielectrics. Wherein, the iron powder used in the treatment of iron powder is reduced iron powder, cast iron powder, and carburized high-carbon iron powder through a 60-300 mesh sieve, wherein the carbon content of the high-carbon iron powder is 0.3-7%.

Abstract

The invention discloses a water film oxygen absorbent. A finished medicament comprises processed ferrous powder and reactive group, wherein a ratio in parts by weight of the processed ferrous powder and the reactive group is (0.05-9):1; the processed ferrous powder is characterized in that neutral and alkaline dielectric water film layers are compounded on the surface of the ferrous powder. The invention discloses a preparation method of the water film oxygen absorbent. The water film oxygen absorbent is capable of effectively solving the problems of the great possibility of generating dehydrogenation depolarization corrosion reaction of the conventional deoxidant, mono-property and small application range of the conventional deoxidant. The water film oxygen absorbent is applicable to the sealed placess for absorbing oxygen and / or absorbing oxygen, carbon dioxide and inert gas and also applicable to the sealed places needing to be disinfected at the high temperature, the freshness retaining places at the storage temperature being lower than 4 DEG C and the sealed places with ultra-dryness or extra-high humidity.

Description

technical field [0001] The invention relates to a formula of a water film oxygen absorbing agent and a preparation method thereof, which are used for deoxygenation, preservation and storage, and belong to the technical field of food preservation and product storage. Background technique [0002] At present, the oxygen-absorbing agent or double-absorbing agent products circulating on the market in our country mainly include: the first domestic oxygen-absorbing agent "801" and its derivatives developed by the applicant as the chief technology officer, and the "Double-absorbing agent" invented by the applicant. Type fresh-keeping and sealing agent" (referred to as 504 double absorbent, patent number: ZL88105412.7) and its series of products. The "801 oxygen scavenger" and "504 double absorber" mentioned above all use reduced iron powder and cast iron powder as oxygen absorbing components, and use water-containing particles, salts, activated carbon and / or dry rice husk ash to fo...
