Abstract
The invention relates to a vermiculite double absorber/oxygen absorber. The double absorber (O2&/CO2 absorber)/oxygen absorber product taking vermiculite and/or diatomite and/or carbon white as main water absorption materials comprises the following components: 60 to 83 percent of iron powder, 9 to 39 percent of water-containing particles, 0.5 to 12 percent of salts, 0 to 12 percent of active carbon, 0-14 percent of lime and so on. The double absorber/oxygen absorber belongs to the technical field of deoxidized storage, and can be used for food preservation and product storage.
Description
Technical field
Vermiculite double-suction agent/oxygen absorbent of the present invention is meant with vermiculite and/or diatomite and/or white carbon makes a kind of double suction agent (O that the suction main material is mixed with
2﹠amp; CO
2Absorber)/oxygen absorbent (O
2Absorber) product belongs to deoxygenation and seals technical field up for safekeeping, can be used for food fresh keeping, product is sealed up for safekeeping.
Background technology
The first oxygen scavenger of China " 801 " came out in nineteen eighty-two, and I participate in and led (Technical Team Leader) this product development, knew that therefore this product mainly makes absorbent material with active carbon, butt rice hull ash; The first double suction agent of China " 504 " is first patented product (ZL88105412.7) of my application in application patent of invention in 1988, and it makes main absorbent material with active carbon, lime.Popular oxygen scavenger, double suction agent all is the derivative in above two product promotions on the present city field boundary, and therefore above two products are representative.These products all exist the relatively low problem of ability to take oxygen.Its reason is that the water absorbing capacity of the used absorbent material active carbon of these products, lime, butt rice hull ash is too low, has limited the raising of iron content in the prescription.Usually add the reactive group that salt is made into these absorbent materials, its water content is no more than 32%; Add the product that oxygen uptake composition iron powder is made into this reactive group, its iron content generally is no more than 65%, and the about 100～125ml/g of the actual level that reaches of unit oxygen absorbed generally is no more than 140ml/g.
Summary of the invention
For the certainly relatively low problem of existing product ability to take oxygen that is situated between, the present invention proposes and use vermiculite and/or diatomite and/or white carbon to replace active carbon, lime, butt rice hull ash do suction main material, add the reactive group that salt is mixed with, certainly this problem that can be situated between effectively can be brought up to 150～220ml/g level to the unit oxygen absorbed.
The technical scheme of vermiculite double-suction agent/oxygen absorbent of the present invention is:
A kind of double-suction agent/oxygen absorbent, by iron powder, contain compositions such as water particle, salt and form, its major technique is characterised in that---
(1), contains iron powder 60～83%;
(2), contain water particle 9～39%;
(3), contain salt 0.5～12%;
(4), contain active carbon 0～12%;
(5), limy 0～14%;
Composition in the prescription (1) is basic oxygen uptake composition, requires granularity generally more than 60 orders, and kind is not limit; Composition in the prescription (2) (3) (4) (5) anabolic reaction base, requiring the moisture content excursion is 25～59%; Reactive group can be shaped separately and be made into semi-finished product aborning, can require (oxygen absorbent) or oxygen uptake/suction carbon dioxide to require (double suction agent) to choose some parts of iron powders then according to oxygen uptake and mix with 1 part of reactive group and be made into the finished product medicament, the iron powder excursion can not be subjected to above-mentioned formulation restrictions at this moment.
Composition in the prescription (2) is vermiculite, diatomite, white carbon for the oxygen uptake reaction provides required moisture content, material therefor, and these materials all have very strong water absorbing capacity, can independent or reasonably combined use.Theoretically, the gram iron powder process of getting rusty can absorb 305ml oxygen approximately, consume about 0.16 gram water (generation Fe
2O
3H
2During O) or 0.48 gram water (generation Fe (OH)
3The time).Moisture content is not enough, and the oxygen uptake reaction is normally carried out with regard to difficulty, so moisture content is a kind of requisite important composition, and composition (2) institute water content can be selected for use in 40～71% scopes according to particulate material, to guarantee reactive group requirement moisture content;
The used salt of composition in the prescription (3): salt, calcium chloride, sulfate, sulphite, can independent or reasonably combined use;
Composition in the prescription (4) is used to eliminate peculiar smell and reaction speed, can select for use according to instructions for use, and reacting Su Du Sui activated carbon dosage usually increases and accelerate;
Composition in the prescription (5) is used for absorbing carbon dioxide and regulates acid-base value making PH 〉=7, can be according to the requirement of prescription PH 〉=7 and in using to the absorbing carbon dioxide amount what requirement choose consumption;
Because used iron powder no matter aerobic whether hydrogen all can take place goes the Veryization corrosion reaction, makes packaging bag a bloated bag of air-blowing phenomenon take place in storage, cause product rejection under acid condition in the prescription, thus this product requirement prescription be in, alkalescence; On the Cong Zhe Ma meaning, as the stable product of shelf characteric, the iron-based oxygen absorbent that some carbon dioxide are not inhaled almost is non-existent, and this paper is named the double-suction agent/oxygen absorbent reason and just is this;
Use for convenience, we seal the absorbing carbon dioxide amount product of environmental gas concentration up for safekeeping double suction agent (O greater than 2% in production application
2﹠amp; CO
2Absorber), being used for the field boundary that requirement will absorb oxygen and carbon dioxide gas simultaneously closes; The absorbing carbon dioxide amount is not more than 2% seals the product of environmental gas concentration up for safekeeping oxygen absorbent (O
2Absorber), be used for requirement and need do not absorb the field boundary of carbon dioxide and close, this moment, above-mentioned prescription lime consumption generally was no more than 1%.
Ordering-the invention vermiculite double-suction agent/oxygen absorbent and existing product relatively have ability to take oxygen Strong, and unit oxygen absorbed height can be prepared universal, drying type, high energy type, the multiple double suction agent of high wet type (O
2﹠amp; CO
2Absorber)/oxygen absorbent (O
2Absorber) product, of many uses, advantage is obvious, seldom gives unnecessary details.
