Description
Technical field
The present invention relates to deoxidier, be specifically related to a kind of difunctional quick dehumidifying/deoxidizing agent and preparation method thereof.
Background technology
In recent years, the strong request to improving the food antiseptic fresh-keeping effect makes foodstuff package inside be in hypoxemia and low wet condition at short notice, thereby the inhibition Food Oxidation goes bad or makes moist.Specifically, be with quick dehumidifying/deoxidizing agent with pack into the inside of foodstuff package of food, to reduce foodstuff package inner residual oxygen concentration and humidity, guarantee that food can be not putrid and deteriorated.
Deoxidier that is formed by organic type of material and the deoxidier that is formed by mineral-type materials are arranged at present.Consider from cost, security aspect, mainly use the iron series deoxidizers of inorganic material.In the application of reality, iron series deoxidizers and oxygen reaction must have enough moisture, and the water deficient in the atmosphere is so that oxygen drops to lower concentration, so need in the deoxidation component, add a spot of water usually; And, also need add the water imbibition material in order to guarantee that deoxidier has the dual-use function of dehumidifying, deoxidation.Add water for the deoxidation component, can influence the effect of dehumidifying, the water imbibition material also can influence the effect of deoxidation simultaneously.Therefore the most existing iron series deoxidizers has only the effect of deoxidation usually, and does not possess the function of dehumidifying.This to a great extent limit the use of such deoxidier, especially aspect the preservation of article such as dried food and nuts food, tealeaves.Though it is difunctional that some iron series deoxidizers has the dehumidifying deoxidation at present; Like Chinese patent " bactericidal dehydration and deoxidation preserving agent and preparation method thereof " (publication number: CN101199360A; Open day: on June 18th, 2008); Announced that a kind of iron is but that dehydration and deoxidation preserving agent this patent have only been listed the potential scope of application of dehydration and deoxidation agent, lacks concrete dehumidifying deoxidation data.。
Summary of the invention
The object of the invention is exactly in order to solve the problems referred to above that deoxidier of the prior art exists; Through a large amount of experiments, developed and a kind ofly can remove the oxygen in the atmosphere effectively, can remove the difunctional quick dehumidifying/deoxidizing agent of the moisture in the atmosphere again effectively; This difunctional dehumidifying/deoxidizing agent production technology is simple; Raw material is easy to get, and is with low cost, is convenient to industrialization promotion.
Technical scheme of the present invention is following: iron and copper sulphate reaction generate copper; Original position forms copper iron galvanic cell; Oxygen in so just can fast Absorption atmosphere consumes the moisture in the deoxidation component simultaneously, thereby the water influence dehumidifying of having alleviated in the deoxidation component has also been alleviated the water imbibition material to the oxygen uptake Effect on Performance.Slaine such as copper chloride, chloroplatinic acid and iron effect and copper sulphate have similar principle.Experimental result shows that adding the deoxidation component that constitutes behind copper sulphate, chloroplatinic acid or the copper chloride can utilize moisture efficiently, reaches the effect of quick deoxidation; Also suppressed simultaneously the dehumidifying component and absorbed the moisture in the deoxidation component, alleviated of the influence of dehumidifying component deoxidation speed.
Difunctional quick dehumidifying/deoxidizing agent of the present invention by the deoxidation component with the dehumidifying component form, said each component of deoxidation component and quality percentage composition (being the percentage that each constituent mass accounts for the dehumidifying/deoxidizing agent quality) thereof as follows:
Iron powder 32%～47%, auxiliary agent 0.03%～1%, catalyst 3%～7%, filler 9%～18%, sulfuric acid 0.3%～0.5%, water 7%～10%, wherein auxiliary agent is a metallic salt;
The quality percentage composition of said dehumidifying component is 30%～38%.
Iron powder is a deoxidation component main body, is preferably 100～200 purpose reduced iron powder or cast iron powders.
Said metallic salt is the salts substances of copper or the acids or the salts substances of noble metal, and wherein the salts substances of copper is cupric sulfate pentahydrate or copper chloride dihydrate, and the acids of noble metal or salts substances are chloroplatinic acid, gold chloride, palladium bichloride etc.
Said catalyst is more than one in sodium chloride, potassium chloride or the calcium chloride.
Said filler is two or more in active carbon, silica, kaolin, diatomite or the carbon fiber.
Said dehumidifying component is more than one in calcium oxide, the silica gel.
The preparation of above-mentioned difunctional quick dehumidifying/deoxidizing agent, its step is following:
1) by proportioning catalyst, auxiliary agent, the concentrated sulfuric acid and water are mixed after, stir rapidly;
2) by proportioning adds iron powder in step 1) after, stir 0.5～5min, make iron powder be able to activation, and with auxiliary agent in metal formation galvanic cell;
3) by proportioning again to step 2) in the adding filler, stir, obtain the deoxidation component;
4) with after the sealing of deoxidation component, put into obturator together with the dehumidifying component again and seal, promptly obtain dehumidifying/deoxidizing agent.
Difunctional quick dehumidifying/deoxidizing agent provided by the present invention can absorb oxygen and the moisture of removing in the atmosphere.
Compared with prior art, the present invention has the following advantages:
(1) dehumidifying/deoxidizing agent of the present invention can make the oxygen in the closed container drop to below 5% in a period of time, and humidity drops to below 13%, is applicable to the fresh-keeping and article preservation of numerous food.
(2) among the present invention, iron powder and auxiliary agent constitute galvanic cell, accelerate the speed that oxygen is removed in the confined space
,Consume the moisture in the deoxidation component simultaneously fast, thereby alleviated the water influence dehumidifying in the deoxidation component, not only reach the difunctional effect of dehumidifying deoxidation but also shortened the time.
(3) preparation technology of the present invention is simple, add easy to use, safe, persistent, cost of manufacture is low, the scope of application is extensive, is convenient to suitability for industrialized production.
