Summary of the invention
The objective of the invention is to be to provide a kind of fast, high temperature, efficient, safe, inexpensive nothing fire heat-generating agent, after suitable packing, be mainly used in the direct heating of the box-packed various food and drink of metal tin.Also can for example be used for sterilization, dehydration and degraded as other occasion that needs flames of anger heating at environmental protection field heating waste.
As everyone knows, most dehydration inorganic salt all have hydrated reaction heat in various degree, and partial dehydration salt also has the solidification heat after the aquation.The active calcium oxide that Wingdale makes after calcining is a kind of siccative cheap and easy to get and heat-generating agent.Through screening and optimum combination, having constituted in the technical scheme of the present invention with dehydration aluminium strong acid salt and non-aluminium strong acid salt is acidic components, is the chemical heating agent prescription and the compound method thereof that startup is quick, high temperature efficient, safety is inexpensive of basic component with active calcium oxide, sodium hydroxide, potassium hydroxide etc.At least by the hydration heat of material, acid-base neutralisation heat release and curing exotherm three parts constitute its thermal value.
Heat-generating agent of the present invention comprises 40-120 weight part dehydration aluminium strong acid salt, the 10-50 weight part non-aluminium strong acid salt that dewaters, 20-200 weight part alkaline components, 0.5-15 weight part raising agent, optional an amount of spices (being generally the 0.01-0.5wt% of heat-generating agent), 20-300 weight part primer fluid.
Preferred heat-generating agent of the present invention comprises 60-80 weight part dehydration aluminium strong acid salt, the 20-40 weight part non-aluminium strong acid salt that dewaters, 20-180 weight part alkaline components, 1-10 weight part raising agent, 20-300 weight part primer fluid and optional an amount of spices (being generally the 0.01-0.5wt% of heat-generating agent).
The aluminium strong acid salt that wherein dewaters comprises dehydration Tai-Ace S 150, the dehydration aluminum chloride, and dehydration aluminum nitrate etc., dehydration Tai-Ace S 150 is particularly preferred; The non-aluminium strong acid salt that wherein dewaters comprises dehydration sal epsom, the dehydration manganous sulfate, dehydration ferric sulfate, dehydration copper sulfate, dehydration zinc sulfate, dehydration magnesium chloride, the dehydration cupric chloride, the dehydration zinc chloride, the mixture of one or more in the dehydration Manganous chloride tetrahydrate etc., the sal epsom that wherein dewaters, dehydration manganous sulfate, dehydration ferric sulfate are particularly preferred.
Industrial salt hydrate drying dehydration, the fragmentation of above-mentioned salt can be sieved and made described dehydration salt.
Alkaline components comprises active calcium oxide, no water sodium hydroxide, anhydrous potassium hydroxide etc., or the mixture of their arbitrary proportions.Active calcium oxide is preferred.Active calcium oxide be by with Wingdale through 900-1200 ℃ of calcining, fragmentation is sieved and is made, optimum burning temperature-forming will be determined by experiment according to the difference in Wingdale source.Simple definite method is: get calcined crushed piece grain and place water, immediate response presents the explosion phenomenon and is considered as active good.The active calcium oxide component also can be by white lime, and promptly calcium hydroxide is raw material, behind 500-600 ℃ of decomposition calcination for activation, makes through the granulation of adhesive-free tablets press again.Under the situation of using no water sodium hydroxide, potassium hydroxide etc., consumption answers the specific activity calcium oxide little, for example is generally the 10-60 weight part.And need now with the current.
Raising agent is raising agent commonly used, salinization haydite for example, and gac etc., the raising agent that wherein have fluffing action, has exothermic effects concurrently simultaneously is most preferred.
The salinization haydite is a common building haydite particle, and its main component is a silico-aluminate, soaks into through saturated sodium carbonate liquid, and drying makes again.It and water also produce thermopositive reaction.Improve the hydrophobicity of material after allocating into, improved the exothermicity of material.
The optional trace that adds or a small amount of spices are because how much inorganic dehydration salt has some peculiar smell when hydration reaction, and allocating the back into is that people can accept the degree until comfortable smelling good to remove, to align its smell.
Primer fluid can be ortho-water (as a tap water), beverage, and the aqueous solution etc. also can be weak acid or weakly alkaline fruit juice or other solution with urine or other in the occasion of lack of water and replace.When needs start, with water and heat-generating agent solid materials intermingling.
The heat-generating agent that adopts the arbitrary formulated in the said components prescription with water or urinate mix after, all have identical or close heating property.The consumption that is suitable for heating the primer fluid of diet jar box is the 50-100 weight part.
The material behavior of the technology of the present invention with the heating cardinal principle is:
Except that spices, each component is met water separately and is all produced thermopositive reaction in the prescription.With above-mentioned ready separately component all fragmentation sieve greater than 20 orders, diameter mixes to constitute less than 5 millimeters particle mutually looks the solid materials that specific volume is the 0.60-0.95 grams per milliliter.In several seconds to tens seconds, start thermopositive reaction fast after meeting water.Acidic components start fever time as the increase of sal epsom amount and shorten with the non-aluminium strong acid salt of dehydration, and total material is with alkaline components, and for example the activity of active calcium oxide increases, dosage increases and starts the fever time shortening.It is 105-175 ℃ that material is met water self-heating temperature, raises with the minimizing spontaneous heating temperature that adds the water yield, and the abundant degree of reaction reduces thereupon.The spontaneous heating time can continue several minutes.More for a long time, with the increase or the macrobead increasing proportion of solid particulate, the spontaneous heating reaction times prolongs in the water yield.Thermal value is made up of hydration heat, acid-base neutralisation heat release and curing exotherm three parts of material at least.When being suitable for heating diet jar box primer fluid consumption and being the 50-100 scope, the solid material melted thing in the pasty state when water vapor was emerged in reaction, became the solid piece grain with cooled and solidified at last, and its composition is the mixture of oxyhydroxide and complex vitriolate.Litter after the disposable use is water-soluble, and the aqueous solution is slightly acidic or weakly alkaline.The pH value of the complete material of reaction all approaches neutrality when active and proportioning is all suitable, and environment is not polluted.Wherein the Tai-Ace S 150 components selection is under harmless, cheap prerequisite, and in optional metal sulfate scope, it is not only the hydration heat value for maximum, always releases the big and aquation of acid amount and releases the acid-respons gentleness, presents the characteristics of releasing acid by rank.Can obtain maximum acid-base neutralisation heat like this, and reaction solution acidity is not high, has also prolonged the heat release time.Its aquation is released sour process and can followingly briefly be described:
The composition of the Litter that this reaction is finished is oxyhydroxide or the complex vitriolate or their mixture of original component such as its aluminium of forming, calcium, sodium, potassium, magnesium, manganese, iron, copper, zinc, and abandoning the back is harmless to water quality and soil on every side.In use just in case sputter on hand or the clothing, just through washing or soak self-dissolving.Heat-generating agent only needs drying and dewatering and calcined limestone and the fragmentation operations such as mixing of sieving in process for preparation, all be that nontoxic atmosphere can not cause big pollution to environment.Can be in the storage and transport process because of accident such as blast such as vibration, collision, solar radiation.As long as the nonhygroscopic preservation that just can the long period of sealing is effective.So this is a kind of safe in utilization, environment-friendly type heat-generating agent.
Heat-generating agent provided by the present invention, raw materials used wide material sources are abundant, cheap, the preparation convenient, production and use and Litter environmentally safe, start that heat release is rapid, thermal value is big, heating temp is high, exothermicity is good.Adopt suitable packing just to can be used to direct heating diet product and be used for the occasion that other can not have naked light heating.
