Chemical hot bag

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 [0001] The invention relates to a chemical heat bag, which belongs to the technical field of chemical heating. Background technique [0002] The chemical heat bag is mainly made of the principle that the temperature inside the bag rises rapidly by utilizing the exothermic chemical reaction to obtain heat. It is mainly used in people's heating or hot compress physical therapy of the human body, etc., and has good effects. In short, chemical heat bags play a relatively important role in daily life. [0003] Chemical heat bag is one of the best-selling products in the winter market. The common chemical heat bag is mainly made of inorganic salt, iron powder and activated carbon. This is mainly due to the use of electrochemical principles, the heat generated by the oxidation reaction of iron powder. This principle is also not difficult to find in Chinese patent literature, discloses a kind of name as the chemical heat bag of " a kind of heating bag " (publicati...
