Description
Technical Field
The invention belongs to the technical field of quick refrigerants, and particularly relates to a refrigerant capable of being used for a closed self-refrigeration pop can.
Background
At present, cold drink products are stored through a refrigerator and a freezer before being purchased, and can be eaten after being purchased by a purchaser, but the storage condition of the cold drink is realized under the condition of power-on, but the stable storage of the cold drink cannot be realized in remote areas or under the condition that the stable power supply cannot be realized.
In view of the above problems, it is a technical problem to be solved in the art that how to provide a product that can be operated by a user to produce a cold drink as a current instant food through technical innovation, and the operation can be implemented safely, stably, conveniently and cheaply.
Disclosure of Invention
As a technical personnel in the industry, it is very necessary to develop a refrigerant which can be used for a closed self-refrigeration pop can, can solve the defects in the prior art, and has the advantages of safety, stability, no pollution and low price in the use process.
The technical scheme of the invention is described as follows: the paint comprises the following components:
according to the weight ratio: 45-60% of ammonium nitrate, 5-15% of an anti-riot inhibitor, 20-30% of carbamide and 20-30% of water.
Ammonium nitrate: absorbs heat through dissolution hydration reaction and is a main component of refrigeration.
Anti-riot inhibitors: the anti-riot inhibitor adopts potassium chloride or sodium chloride or monoammonium phosphate; because the ammonium nitrate is an explosive substance, the violent reaction of the ammonium nitrate in the transportation and use process can be effectively prevented by fully mixing the anti-explosion inhibitor and the ammonium nitrate.
And (3) carbonamide: the heat absorption is realized through the dissolution hydration reaction, and the refrigeration is assisted.
Water: solvent for hydration reaction, heat transfer medium.
The refrigeration principle can be embodied by the following chemical formula:
NH4NO3 ═ NH4+ + NO3- (dissolution enthalpy), which is a dissolution hydration reaction, according to the above formulation requirements, with a solubility in the range of 0-45 ℃.
The reaction is a dissolution hydration reaction, and the CO (NH2)2 ═ NH4+ + CO3- (dissolution enthalpy) may be in a proportion of solubility in the range of 0 to 45 ℃.
The reaction mainly uses ammonium nitrate, excessive addition of carbamide can influence the dissolution of nitric acid, and the carbamide can reduce the proportion as required, so that the aim of fully utilizing water and maximally dissolving, absorbing heat and refrigerating is fulfilled.
The invention has the beneficial effects that:
compared with the existing refrigeration mode, the invention has the following beneficial effects:
1. the refrigerant has no gas generation in the reaction process, can be suitable for use in any place, is not limited by a closed space, and is not limited and influenced by the actual environment of a use site;
2. the refrigeration reaction speed is controllable, the reaction time is short, the reaction can be fully completed within 1 minute, and after the reaction is finished, the zip-top can product can be subjected to harmless treatment;
3. the reaction refrigeration is controllable, the reaction refrigeration can be accurately prepared according to the heat requirement, when the quantitative refrigerated object is refrigerated, the powdery material can be prepared in advance according to the proportion, and a user can realize quantitative proportioning by adding quantitative water according to the specification requirement;
4. all the components can be obtained from the existing industrial materials, and the materials have low price and low manufacturing and using cost, thereby being convenient for large-scale popularization in the field.
5. Can be manufactured along with the package of drinks or cold food products, can be used at any time when needed, and saves energy sources required by cold storage drinks and foods to a certain extent.
6. The reacted matter of ammonium nitrate and carbamide can be used as agricultural fertilizer for plant growth and has no pollution to land.
Detailed Description
The invention is further described below with reference to examples.
In order to better explain the invention, the invention is further illustrated with reference to the following examples, but the invention is not limited to the following examples.
Example (b):
according to the weight ratio: 50 g of ammonium nitrate, 10 g of antiriot inhibitor, 20 g of carbamide and 20 g of water, and the chemical formula is as follows:
the reaction mainly uses ammonium nitrate, excessive addition of carbamide can influence the dissolution of nitric acid, and the carbamide can reduce the proportion as required, so that the aim of fully utilizing water and maximally dissolving, absorbing heat and refrigerating is fulfilled.
According to the technical scheme, the actual refrigerating capacity can be accurately measured and calculated through the two reaction equations. Measuring the initial temperature of 300ml of water by using a digital thermometer at 20 ℃, putting 50 g of ammonium nitrate particles into the water completely, stirring fully, continuously measuring the water temperature until the temperature is not reduced any more, measuring the lowest temperature C1, and finally obtaining the refrigerating capacity delta C/g of ammonium nitrate in unit mass;
the specific heat capacity of all substances and containers is fully considered when the refrigeration capacity is measured, the experimental environment is used, the loss of the cold quantity is controlled so as not to influence the calculation accuracy, and the refrigeration usage amount of the actual product can be obtained through the experimental data and the supplement of various substances added.
The method comprises the following steps: 50 g of ammonium nitrate and 10 g of potassium chloride are fully mixed, 20 g of carbamide is mixed with the mixture after the mixing is finished, 20 g of water is poured into the mixture after the mixing is finished, and the mixture is kept stand for 2 minutes to realize the complete reaction.
When the technical scheme is used as a finished product heating formula, attention needs to be paid to the following steps: mixing ammonium nitrate and carbamide according to the required proportion to form a reaction medicament which is necessarily moisture-proof; packaging the prepared aqueous solution by using a sealing device; the ammonium nitrate must not be shaken vigorously when mixed thoroughly with the anti-knock agent.
