The crystal salt lamp can radiate natural negative ions, especially in the heated state, and can effectively balance the content of positive and negative ions in the air. It is a natural air purifier. The main component of the crystal salt rock is sodium salt. The salt lamp absorbs water from the air, and then evaporates, absorbs water, evaporates again and again, and generates negative ions continuously in this process. The heated salt lamp absorbs the water molecules in the surrounding air to the surface. When the salt is mixed with the water molecules, it will dissolve. After the water evaporates, Na+ and Cl- return to the neutral state, and the evaporated water carries The negative ions produced by the ionization of water molecules, so the air is purified by this constant reaction. This unique ion generation process is only available in crystal salt mines because the electrically neutral atomic structure of the salt mine determines the ability of the salt mine to generate such negative ions in the presence of water.
According to expert statistics, salt lamps can increase 500-700 negative ions per cubic centimeter of air, plus the negative ions originally contained in indoor air can effectively improve the quality of indoor air. It is especially suitable to be placed beside electrical appliances such as computers and TV to neutralize positive ions and shield the harmful radiation of electrical appliances.
