Description
Technical field
The present invention relates to a kind of exothermic mixture and preparation method thereof, specifically a kind of exothermic mixture and preparation for food heating
Method.
Background technique
Exothermic mixture typically refers to heat of solution or the heat of oxidation to be generated with chemical reaction and reaches fever purpose hair as heat source
Thermit powder；Exothermic mixture is mainly the mixture that is made of aluminium, calcium oxide, copper oxide and zinc oxide etc., at the same also often containing other one
A little additives, such as adhesive and filler.The heat that the burning of exothermic mixture releases rapidly and when burning, has its applicability
There is decisive influence.In addition, its thermal conductivity and fusion temperature etc. also influence its applicability；It generates heat made of this exothermic mixture
Bag (body) is not required to thermal water source compared with usually used hot-water bottle, and temperature is stablized, and can choose thermophilic, the duration is long
The features such as, therefore, purposes is more extensive, such as warms oneself for field emergency, emergency, hand warmer, foot warmer, food heating and defrosting,
Pesticide fumigation, plastically welding, oxygen detection etc. can compare far from hot-water bottle, especially outdoors, heat food using exothermic mixture
With extremely widespread.
Currently, existing exothermic mixture burning velocity is slow, heating efficiency is low or local temperature is excessively high, while material cost is high,
Not easy to store, portability is also poor, needs non-toxic heating for food heating, and part heating agent is not available, and existing
There is exothermic mixture packaging not of uniform size, it has not been convenient to quantitatively be used according to food weight.
Summary of the invention
The purpose of the present invention is to provide a kind of exothermic mixtures and preparation method for food heating, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the invention provides the following technical scheme:
It is a kind of for food heating exothermic mixture, including calcium oxide, calcium hydroxide, copper oxide, zinc oxide, aluminium, sodium carbonate and
The weight percent of sodium bicarbonate, component is as follows: calcium oxide 20%~45%, calcium hydroxide 1%~10%, copper oxide 1%~10%,
Zinc oxide 1%~10%, aluminium 30%~50%, sodium carbonate 0.1%~10%, sodium bicarbonate 5%~19%.
As further scheme of the invention: adding anti-oxidizing agent in the exothermic mixture, it is ensured that aluminium powder is producing
With it is not oxidized during preservation.
A kind of preparation method of the exothermic mixture for food heating:
Calcium oxide, calcium hydroxide, copper oxide, zinc oxide, aluminium, sodium carbonate and sodium bicarbonate are granulated by the first step respectively
Processing, and partial size is between 0.1-3mm；
Calcium oxide, calcium hydroxide, copper oxide, zinc oxide, aluminium, sodium carbonate and sodium bicarbonate are carried out quantitative title by second step
Weight is then mixed by batch mixer；
Third step is quantitatively packed into nonwoven bag after mixing evenly and is sealed；
4th step, nonwoven bag outside carry out plastic film environmental sealing.
Compared with prior art, the beneficial effects of the present invention are:
The present invention is long relative to existing exothermic mixture duration of the reaction, and can guarantee heating food needed for high temperature, nontoxic nothing
Evil, the prices of raw materials are cheap, and dosage is few, and manufacturing cost is lower, while under the action of nonwoven bag, trip being facilitated to be carried,
Also meet the needs of mass and automated production, convenient for unified standard, become since calcium oxide easily absorbs the moisture in air
At calcium hydroxide, without easy to maintain, under the package of plastic film, be conducive to long-term preservation, so that present apparatus stability is more preferably,
It is easier to market transport and promotes, the present invention is suitable for crowd and environment is extensive, reduces cooking time and condition.
