Abstract
The invention discloses a chemical hot bag. The chemical hot bag is prepared from the following components in parts by weight: 50-70 parts of iron powder, 20-40 parts of activated carbon, 1-5 parts of sodium chloride, 30-40 parts of silica sand, 30-50 parts of calcium carbonate, 2-6 parts of sodium peroxide, 5-9 parts of sodium sulfate and 50-70 parts of water. The chemical hot disclosed by the invention is high in heating temperature and long in heating time.
Description
Technical field
The present invention relates to a kind of chemical heat bag, belong to chemistry and heat technical field.
Background technology
Chemical heat bag, mainly utilizes exothermic chemical reaction and obtains heat, and the principle that the temperature in bag is raised rapidly and making.It is mainly used in the heating of people or the hot compress physiotherapy etc. of human body, has good effect.In a word, chemical heat bag, plays an important role in daily life.
Chemical heat bag, be one of best-selling product on market in winter, common chemical heat bag, it is mainly made up of inorganic salt, iron powder and gac.This mainly utilizes electrochemical principle, and iron powder there occurs the heat that oxidizing reaction sends.This principle is also not difficult to find in Chinese patent literature, as Chinese patent literature discloses a kind of name and be called the chemical heat bag of " a kind of heating bag " (publication number: CN 1572263 A, publication date: on February 2nd, 2005).It is the chemical heat bag be made up of iron powder 25 ~ 85%, inorganic salt 1 ~ 12%, gac 3 ~ 50%, water 0 ~ 40%.In order to find the composition of better chemical heat bag, people conduct in-depth research chemical heat bag, and obtain certain achievement.As Chinese patent literature [application publication number CN 102936489 A; Shen Qing Publication day 2013.02.20] report the chemical heat bag be made up of calcium carbonate 50 ~ 75%, gac 10 ~ 30% and water 15 ~ 30%.This chemical heat bag heating effect is good, and production cost is low, but single owing to heating comparison of ingredients, heats the time not long.Therefore, develop a kind of new chemical heat bag and very important effect is played to people.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention proposes a kind of chemical heat bag heating time length.
The present invention for the taked technical scheme that solves the problem is:
A kind of chemical heat bag, is made up of each component of following weight: iron powder 50 ~ 70 parts, gac 20 ~ 40 parts, 1 ~ 5 part, sodium-chlor, silica sand 30 ~ 40 parts, 30 ~ 50 parts, calcium carbonate, sodium peroxide 2 ~ 6 parts, 5 ~ 9 parts, sodium sulfate, 50 ~ 70 parts, water.
Its weight is as follows:
Iron powder 60 parts, gac 30 parts, 3 parts, sodium-chlor, silica sand 35 parts, 40 parts, calcium carbonate, sodium peroxide 4 parts, 7 parts, sodium sulfate, 60 parts, water.
In the present invention, make use of the principle that electrochemical reaction produces heat, wherein metallic iron, gac, sodium-chlor form galvanic cell, and carbon is the positive pole of battery, and iron is negative pole, and sodium-chlor is electrolyte solution.Silica sand main component is silicon-dioxide, and it is good that it has chemically stable, the adsorptive power that thermal expansivity is low and strong.Wherein, strong adsorptive power, can make energy be gathered in a certain region, reduces power loss, adds the time of heating.Due in galvanic cell, ferrous ion and hydroxide radical react, and reduce the hydroxide radical of solution, make solution become acid.In the environment of acidity, calcium carbonate and acid react, the evolution of heat, increase and heat the time.Peroxidation sodium and water reaction, sends amount of heat, supplements energy in chemical heat bag.The oxygen simultaneously produced, can promote that ferrous hydroxide becomes iron hydride, continues heat release.Sodium sulfate electrolyte supplement effects of ion.
The invention has the beneficial effects as follows:
The present invention not only make use of common electrochemical reaction and heats, and utilizes peroxidation sodium and water reaction to heat, and increases heat widely, extends the time of heating.Meanwhile, also use the adsorptive power that silica sand is strong, make energy be gathered in a certain region, reduce power loss, add the time of heating.
