Tourmaline (Chemical equation NaR3Al6[Si6O18][BO3]3(OH,F)4) belongs to the trigonal crystal system and occurs as long, slender to thick prismatic and columnar crystals that are usually triangular in cross-section, vitreous luster, resinous luster in sections, It is transparent to translucent and non cleavage with 7.0 - 7.5 Mohs hardness range and Specific gravity range from 2.98 to 3.20, Tourmaline shows pyroelectricity in addition to the piezoelectric, the tourmaline can generate negative air ions spontaneously and emit far infrared rays due to It's unique polar crystal structure.
The effect of potential difference, agitated by temperature and pressure change, could trigger ionization and generates Negative Ions for air purification. The application of super fine tourmaline powder in Terylene could build up or strengthen the functions such as infrared heat retention, deodorization, negative ions generation under room temperature condition and anti-bacteria performance, which make it well known as "magic fiber".
Size: 200mesh, 325mesh, 600mesh, 1250mesh, 200mesh and 6000mesh.
Color: Black or grey.
1. The tourmaline powder is mainly used in the fields of environment protection, tobacco, dope, spinning, cosmetics, water and air purifying, defending electoral radiation, health caring stuffs and so on.
2. The tourmaline can absorb the peculiar smell emitted from the paint or colloid.
The powder of tourmaline can be used to defending magnetism and moisture, warm keeping bedquilt, cotton mat, electrical radiation defending shirt, vest, and insole.
3.There are minim elements such as B, F, SRLI, and so on that conduce to the heath of the human body. Moreover, the infrared emitted from the heated super fine tourmaline powder can be used in cosmetics to activate the facial skin, and achieve the goal of disinfection and sterilization.
