In particular, the ultrafine powder of unipolar mineral tourmaline is used as the main additive element, and the corresponding functional powder additive is produced by using the principle that unipolar mineral can ionize air water molecules to generate negative ions, and using rare earth elements to activate and strengthen its negative ion release function. Then the functional powder is combined with the existing ceramic raw materials in a reasonable formula to produce ceramic glazed tiles with the function of releasing negative ions. Negative ion glazed tile has the functions of health care, fitness, odor removal, air purification and formaldehyde elimination.

Negative ions and human health

8? 8 human feelings about negative air ions:

1. In nature, although atmospheric ions are invisible and intangible, people can feel the existence of negative ions. After the thunder and lightning, the air in the wild will be particularly fresh; The air by the sea will be very fresh. On the contrary, too many positive ions in the atmosphere can cause insomnia, headache, upset, high blood pressure and other reactions. For example, in stormy days, in crowded and polluted places, the number of positive ions in the air suddenly increases, which will make people feel upset, headache and fatigue.

8? 8 the nature and efficacy of negative ions:

1. The positive ions in the air are mostly mineral ions and nitrogen ions, and the negative ions are mostly oxygen ions and hydrated hydroxide ions.

2. Positive ions will snatch stable electrons from atoms of other elements, leading to oxidation. On the contrary, negative ions will give electrons to atoms of other elements to stabilize their properties and produce reduction.

3. Neutralization of negative ions into positive ions can produce the effects of deodorization, dust removal, anti-corrosion, anti-bacteria, preservation, decomposition of smoke and formaldehyde, and air purification.

8? 8 negative ions on the environment and health:

1. Improve lung function: After inhaling negative ions for 30 minutes, the lung can increase the oxygen uptake by 20% and expel 14.5% more carbon dioxide;

2. Improve myocardial function: it has obvious antihypertensive effect on cardiovascular system, which can improve myocardial function and increase myocardial nutrition;

3. Improve sleep and enhance memory: negative ions acting on the nervous system can improve the functional state of the cerebral cortex, make people refreshed, have better mental activities, be energetic, improve work ability, improve sleep and enhance memory;

8? 8 negative ions on the environment and health:

1. Promote metabolism and increase the body's disease resistance: it can improve the body's responsiveness, activate the function of reticuloendothelial system and increase the body's disease resistance;

2. Sterilization: the combination of negative ions and bacteria causes structural changes or energy transfer of bacterial viruses, leading to the death of bacterial viruses and no longer forming new varieties;

3. Fresh air: negative ions are combined with smoke floating in the air and precipitated by electrostatic treatment, thus achieving the purpose of purifying the air.
