Negative ion powder, is the principle of human by nature generates negative ions, a complex mineral synthetic or ratio, are generally tourmaline powder + lanthanide or rare earth elements, including rare earth elements ratio greatly exceeds the tourmaline powder, rare earth accounted for more than 60%, is a rare earth to generate negative ions, or tourmaline to generate negative ions, at present academia still open to debate.

Classified according to purpose

(1) the purification of negative ion air negative ion powder in the air movement are presented "Z" shape of the. And conveying a negative charge to the bacteria, dust, smoke particles and water droplets, and the combination of charge particles together to sink into the ball, so as to achieve the purpose of purifying air.

(2) to eliminate the leftovers acid odor indoor smell and harmful gases used in interior decoration decoration materials volatile out in the process of benzene, formaldehyde, ketone, ammonia and other irritating gases and daily life, such as the harmful to human cigarette smell, with negative ion powder wall cloth, curtain or contain negative ion powder coating, the release of negative air ions can effectively be eliminated.

(3) the role of health care by the negative ion fiber processing fabrics such as clothing, bed sheets and upholstery wallpaper, carpet, or with negative ion powder coating, has the dual function of health care and environmental protection, such as negative ions fiber fabrics in the car, the car can eliminate endometriosis smell, purify air, adjustable driver's nervous system excitatory and inhibitory state, improve the function of the cerebral cortex to maintain a good state of mind.

(4) with negative ion powder adding filter material for drinking water machine filter water treatment, can kill bacteria in water, increase the dissolved oxygen in the water, with a negative ion fiber towels in the bathroom or for the bath water treatment, can accelerate the movement of water molecules, so that ordinary water into activated water. Increase the energy of human body, easy to remove dirt, eliminate fatigue. After the treatment of water used for high-grade indoor green plants cultivation, can improve the survival rate of the plant, and shorten the period of maturity, spraying to flowers foliage, can make the preservation period of flower 5-10 times longer.
