Steam eye mask is an advanced self-heating and temperature control technology that allows the moisture in the air and iron powder to react chemically inside the eye mask to form a heat generator, producing a fine, warm water vapour that cannot be seen by the naked eye. It is a class of products with a generic name developed in response to the market demand for eye care, which is named because it can spontaneously form heat and generate steam.

The reaction principle of the steam eye mask is that of the rapid oxidation of carbonyl iron powder in contact with oxygen in the air. In order for the temperature to last longer and be more constant, the product uses a very precise breathable film. Because the product cannot react before use, the bag material has to be very special. When in use, the outer bag is removed and the product is exposed to the air for 30 seconds before the oxygen in the air enters inside through the micro breathable film. The time as well as the temperature of the released heat is controlled by the quality of the breathable film. If the oxygen permeation is too fast, and subsequently, there is too much heat, it is very likely to burn the skin. If the oxygen permeation is too slow, the temperature is too low. After use it is a dark brown solid, which contains carbon powder, solids (this is table salt), and salts containing iron.

(1) The external reaction principle of the steam eye mask releases steam evenly through the high-grade medical non-woven fabric, using the warmth of the steam to promote the blood microcirculation of the eyes, relaxing the tense eye muscles, and eliminating the fatigue and discomfort of the eyes. (2) The internal reaction principle of the steam eye mask uses the primary battery reaction to accelerate the oxidation reaction speed, transforms the chemical energy into heat energy, and then uses the heat generated to make the water in the internal material evaporate steadily, so as to achieve the effect of using the heat and humidity of the steam to alleviate the fatigue of the eyes, promote the blood circulation of the eyes, and brighten the eyes and refresh the mind. In order to make the temperature can be sustained, and the inner pocket of the heat generating sheet produced is exposed to the air, the oxygen in the air enters inside through the breathable film, and reacts with the iron powder and releases heat. The process of producing steam for the internal material exothermic, so that the rate of evaporation of the water contained in the greatly accelerated, evaporated water vapour in the cold rapid liquefaction, the formation of steam.

(3) reaction equation negative: 2Fe-4e = 2Fe ² positive: O2 + 2H2O + 4e = 4OH – total reaction: 2Fe + O2 + 2H2O = 2Fe (OH) 22Fe (OH) 2 + H2O + ½ O2 = 2Fe (OH) 32Fe (OH) 3 = Fe2O3 + 3H2O

Among them, carbon powder and other substances for the reaction electron transfer, but also for the mixing of substances and the regulation of heat transfer has a certain role. Salt substances with the role of carbon powder is similar.

Carbon powder is a reaction electron transfer substance, and it also plays a role in the mixing of substances and the regulation of heat transfer. Salt substances play a similar role to carbon powder.

Steam eye mask history: Steam eye masks first originated in Japan. Later, Chinese companies developed a series of related technologies and passed the EU standard. Steam eye mask through the warm steam heat, to relieve eye fatigue, eye skin care, vision protection, sleep and other effects.

Steam eye mask use crowd : 1. Excessive eye use, eye discomfort caused by excessive eye use, such as dry eyes, eye fatigue and other symptoms; 2. Long-term insomnia patients; 3. Suitable for computer users, TV users, students; Steam eye mask product efficacy broadcast Promote blood circulation in the eyes, relieve eye fatigue, relax the eye skin, plus help sleep, protect eyesight; replenishment of water to reduce moisture loss, lighten eye wrinkles, dark circles, eye bags, delay eye aging; other eye fatigue, eye problems troubled people to use.
