Summary of the invention
The problem to be solved by the invention is to provide a kind of self-heatings to facilitate heating pack, and the fever starting time is short, reaction speed
Degree is fast, and at low cost, environmental-friendly, solid waste is few, the safety is improved for waste.
In order to solve the above technical problems, the invention the technical solution adopted is that: a kind of self-heating facilitates heating pack, including
Play heating box, hermetic bag, non-woven bag packet and the exothermic mixture of heating container, the exothermic mixture includes by weight percentage
Following components: calcium oxide accounts for 25~35%, and corrosion inhibiter accounts for 3~10%, and sodium hydroxide accounts for 10~15%, and weight regulator accounts for 3~
5%, metallic aluminium powder accounts for 38~45%, and metal magnesium powder accounts for 8~12%, and above-mentioned each component is food-grade;
The exothermic mixture is obtained after above-mentioned each component is carried out physical mixed, is fitted into the non-woven bag, passes through institute
It states hermetic bag to be sealed, when use opens hermetic bag, and the water of three times exothermic mixture weight is added in heating box.
The heating principle of exothermic mixture be based primarily upon two active metals of metallic aluminium powder and metal magnesium powder and water exothermic heat of reaction and
Minerals calcium oxide hydration reaction heat release.Reaction equation is as follows:
Al+3H2O=Al (OH)3+3/2H2+102.1kCal ①
Mg+2H2O=Mg (OH)2+H2+84.4kCal ②
CaO+H2O=Ca (OH)2+15.6kCal ③
Al(OH)3+ NaOH=NaAlO2+2H2O ④
(2) by above equation as it can be seen that energy density (i.e. the calorific value of unit mass pyrogen) 1. and is 2. much larger than
3. metallic aluminium powder and metal magnesium powder are main pyrogens, calcium oxide is auxiliary pyrogen.If only calcium oxide, Shi Bixu
There are many amount wanted, and temperature rise is low, and requirement is not achieved, so the main purpose of the invention is to make main exothermic mixture gold first
Belong to aluminium powder and metal magnesium powder releases contained energy to the maximum extent.But aluminium and water reaction can generate fine and close aluminium hydroxide and cover
It covers in metallic aluminum surface, hinders the progress of reaction.So suitable reaction environment will be provided, sodium hydroxide and hydroxide are utilized
Reactive aluminum generates water-soluble sodium aluminate, thus make fresh metal surface always with water haptoreaction and reach quickly, hold
Continuous, complete exothermic purpose.In addition to sodium hydroxide, pyrogen calcium oxide is assisted to react also generation alkaline matter hydroxide with water
Calcium and alkaline environment is provided, heat is that active metal and calcium oxide cooperation generate in a word.Another important function of calcium oxide is
Heating up triggering aluminum water, the reaction of magnesium water immediately are reacted with water, because magnalium is difficult to react in cold water.It is wanted to reach use
It asks, it is necessary to so that rate of heat production is greater than rate of heat dispation, and rate of heat production will be slightly larger than the hot-fluid conductivity of food product inside box, so
The temperature rise rate that can be needed.Although the more forward main hot stage the better, reaction cannot be made excessively fierce and be difficult to control and produce
Raw dangerous, the invention controls reaction speed by control partial size, dosage of each component ratio.The corrosion inhibiter can adjust heat release
Start the time.Weight regulator have heat preservation, make material dispersion uniformly, diluted material reaction speed, while because price is low
It is honest and clean and reduce cost, when needing the heating pack of different weight, can be used to adjust.
It further, by weight percentage further include 2~4% diatomite and 1~4% coke blacking.Diatomite has
The effect of water-absorbing-retaining heat preservation, reduces the excessive evaporation of moisture and uniform moisture is made to reach various pieces in heating pack.Coke blacking
Have the function of that loose porous structure adsorbs permeability using it and plays catalysis and accelerate and improve material fluidity.
Further, the partial size of the metallic aluminium powder is 46.93-55.68 μm, the partial size 46.93- of the metal magnesium powder
55.68μm.The excessive reaction speed of partial size is slow not to react even, the too small reaction of partial size excessively fierceness and increased costs.
Further, the proportion of the metallic aluminium powder and metal magnesium powder is 4:1.Although the dosage for increasing metal powder can improve
Reaction speed and temperature rise rate, but metal powder can react endless to cause to waste within the desired time, therefore having preferably makes
Dosage.The proportion of metallic aluminium powder and metal magnesium powder can also significantly affect reaction rate simultaneously.
Further, the exothermic mixture is made of the following components by weight percentage: calcium oxide accounts for 29%, and corrosion inhibiter accounts for
7.5%, sodium hydroxide accounts for 10%, and weight regulator accounts for 3.5%, and metallic aluminium powder accounts for 40.5%, and metal magnesium powder accounts for 9.5%.Pass through
Optimum proportioning and so that each component is generated a kind of synergistic effect to having reached preferably reaction speed and exothermal effect.Reaction speed
Raising reach maximum temperature in advance, shorten necessary heating time, meet requirement.
Further, it is added with water-absorbing resin in the non-woven bag, can make to start the time obviously in advance and in reaction process
Middle increase permeability rate accelerates reaction.
Further, the non-woven bag rushes punching technology using water and produces, and the starting time can be made obviously to shift to an earlier date and reacted
Increase permeability rate in the process and accelerates reaction.Non-woven bag also has the characteristics that heat preservation, water-permeable and air permeable but non-material leakage simultaneously.It is only few
Amount ion enters in outer box water, and the PH ≈ 7-8 of water is surveyed with PH test paper, and alkalinity reaches PH=14 or more in wrapping.To provide
Closed high temperature, high alkalinity environment, which are conducive to reaction, to carry out.Material leakage does not make food box keep clean and meet self-heating food to packet
The requirement of enterprise and user.
Further, the corrosion inhibiter is sodium metasilicate, prodan, borax, magnesia, sodium bicarbonate, sodium citrate, winestone
Sour potassium, sodium carboxymethylcellulose, mosanom, glucose, starch, dextrin one or more be combined.Corrosion inhibiter is in alkalinity
Under the conditions of be preferentially adsorbed on metal surface, with OH-Competition, delay start time.
Further, the heating box includes outer box and food Neto, and material is to add graphite formation in polypropylene to change
Property polypropylene is embedded in metal film strips in polypropylene, rate of heat transfer is significantly improved, thus before reaching same temperature rise rate
Exothermic mixture dosage can be reduced and reduce overall cost by putting.
Further, must consider for cost, to have many advantages, such as to hand over as weight regulator tell somebody what one's real intentions are, low toxicity, it is described heavy
Measuring regulator is that one or more of food grade talc powder, calcium carbonate, stone powder, silica, sodium chloride are combined.
The application method of the invention: the water of three times heating agent dosage is added in the outer box of heating box, in Neto
It is put into the food for needing to heat, the hermetic bag outside heating agent is opened, is put into outer box and starts timing, put Neto well, gives heating box
It closes the lid.30-60s fever starting, reach within 9-12 minutes 90 DEG C and kept for 5 minutes or more, 13-15 minutes fever main phases terminated
Temperature is begun to decline.Delay to start the time if necessary, then can increase the dosage of the corrosion inhibiter, if necessary to shorten starting
Time is then either to rush punching technology using water added with water-absorbing resin in the non-woven bag to produce.
The invention has the advantages and positive effects of:
1, metal powder fully reacting means to release more heats in heating pack usage time interval, so capacity usage ratio
It is high.The invention realizes that temperature rise rate is fast by the usage percentage of control each component, can reach institute in a relatively short period of time
Temperature need to be used, while maximum temperature is also met the requirements.The reaction main phase has been spent, usually 15-17 minutes, has been reacted substantially complete
Entirely, temperature also comparatively fast declines, i.e., metal exhausts substantially.That is the heating pack heat of releasing needs before the deadline, it is subsequent to put
Hot unnecessary and waste.
2, by dissecting the heating packet after reaction, find unreacted major ingredient (the greyish black part of color) obviously compared with
It is few, that is, it reacts at the appointed time relatively sufficiently, no material waste.
3, the waste after reacting is mainly that the properties such as diatomite, coke blacking, calcium carbonate, calcium aluminate are stable, nontoxic consolidates
Body substance, solubility is small in water, will not polluted underground water and surface water, common garbage disposal can be worked as.But if activity
Metal reaction is incomplete or surplus is more, will continue to heat release, hydrogen release even contacts other combustibles, highly basic, oxidant etc. and draws
Spontaneous combustion is played, there are security risks.It pollutes the environment simultaneously as a kind of unstable material degradation time length.
