negative ion powder size:80-8000mesh Application: textile, paint, health products, plastics, silica, ceramic products
Tourmaline have the special properties of piezoelectricity and pyroelectricity. So it have the electromagnetic radiation of far-infrared region producing negative oxygen ion to antibacterial and deodorize. So it is used in functional fiber textile and clothing coating materials purifying of drinking water building materials, daily necessaries and composite materials. It can cause electric potential difference when the temperature and pressure change and ionize the air that is producing negative oxygen ions to have the result of air purification. Adding powder of tourmaline into melts of polyester can have the performance of infrared warmth retention and deodorization negative ion emission and antibacterial. So it is called fantastic fiber.
