Today is the beginning of winter, the weather is getting colder, and the cold winter is coming soon. The practicality and safety of the warm baby have once again become important criteria for people to choose and buy warm babies. However, the quality of the warm babies on the market is uneven, and the heat generation and heating time are also different. This is because some manufacturers of warm babies use different quality heating materials in the production process for cost considerations, which determines the practicality and safety of the warm baby.
The heating raw material layer of the warm baby is a mixture of reduced iron powder, vermiculite, activated carbon, inorganic salts, water, etc., which can react with oxygen in the air to generate heat. The iron powder produced by our company has small particle size, good uniformity, and high chemical activity. Compared with traditional iron powder, it has high heat generation, long product life, uniform temperature, and good safety (advantages in the application of warm babies).
Reduced iron powder is used in medical heating patches
Good disposable self-heating materials are materials that the physiotherapy and health care industry has been trying to find. There are many public patents in China that use iron powder for heating, most of which are improved and upgraded based on the formula of warm baby. However, the disadvantages of these methods are mainly reflected in the fact that it is not easy to package during the production process, and it is easy to heat up when in contact with air, causing waste, and reducing the service life of the product; and the water will evaporate quickly during use, and will eventually reduce or lose the heating capacity.
Most mainstream formulas use polymer solid electrolyte (SPE), which is physically blended with reduced iron powder and activated carbon to prepare a solid heating material. The shortcomings of the above-mentioned warm baby formula are solved, and the amount of contact with air can be better controlled during use to achieve controlled release of heat, and the heat release effect is good. It is mostly used for disposable medical products such as heating mounting materials for rubber hard plasters or black plasters, human body hot compress materials, etc.
The reduced iron powder produced by our company, with its excellent chemical activity, high specific surface area, and good uniformity, can react more fully with air than traditional iron powder, and the temperature during the reaction is more uniform, and the heat utilization is more sufficient, and a smaller amount can achieve the same effect.
