The use of negative ions; (1) air purification technology: anion anion powder in the air move is rendered "Z" shape. And transporting negative charge to the bacteria, dust, smoke particles and water droplets, a charge with which the particles combine together into a ball and sink, so as to achieve the purpose of purifying the air. (2) eliminate odors and indoor decoration materials harmful gases used in the process of interior decoration out of the volatile benzene, formaldehyde, ketones, ammonia and other irritating gases and everyday leftovers sour smell of cigarettes and other people The harmful odors, negative ion powder containing wall covering, curtains, etc., or containing anion powder coating, the release of negative air ions can effectively be eliminated. (3) health effects: The anion fiber processing fabrics such as clothing, linens and upholstery wallpaper, carpet, paint and other powders containing negative ions, have a dual function of health and environmental protection, such as the car made with negative ion fiber fabric, can eliminate the car smell, clean air, adjustable driver's nervous system excitatory and inhibitory state, improve the function of the cerebral cortex to maintain good mental state. (4) Water treatment: filter material with negative ion powder is added to water dispenser filter, can kill bacteria in the water, increasing dissolved oxygen, with negative ion fiber bath towels for the bathroom or water, can accelerate the movement of water molecules , so that ordinary water into activated water. Increased energy, easy to remove the body of dirt, eliminate fatigue. Treated water for high-grade green indoor load training can improve the survival rate of plants and shorten maturity, foliage sprayed flowers, fresh flowers can extend 5-10 times.
