Model: Superfine Powder anion ion complex functions is a natural gem-quality mineral powder - tourmaline (tourmaline TOURMALINE) as the main raw material, depending on the functional requirements and use with other inorganic oxides main parts, while using special composite processing technology, decentralized modification has made the release of negative ions and other features of the ultra-fine powder. It can be used as functional additives, widely used in many industries, chemical fiber, textiles, plastics, rubber, building materials, paint, health care, food packaging and aquaculture. Product Specifications Name Appearance light gray powder anion powder particle size (um) D50≤0.5 D97≤1.0, the number of negative ions released D20≤0.1 powder ≥1000 cells / cm 2 / sec products release negative ions in the number (number / cm 2 / sec) fiber (1.0%)> 400 Plastic (1.0%)> 400 paint (0.3%)> 400 total radioactivity level α (Bq / Kg) ≤15.0 total β (Bq / Kg) ≤16.3 Moisture (%) <1.0 The main composition and content TiO2 (%) ≥30 SiO2 (%) ≥27 Al2O3 (%) ≥25 B2O3 (%) ≥5 Fe2O3 (%) ≥3 Features 1, the product of small grain size (1.0μm or less) complex The maximum particle size of less than 1.25μm (more than 10,000 head). Narrow particle size distribution, surface area larger than the surface (interface) activity, and later modified by the composite particles decrease since reunification, and application product compatibility. Automatic efficient and long-lasting release negative ions, but also has far-infrared emission (4-14μm) function, the fresh air, anti-bacterial deodorant, promote micro-circulation, improve the biological immunity. 2, safe non-toxic side effects, raw materials are all non-toxic, non-irritating, non-radiation of natural minerals and inorganic oxides, the use of special equipment and processing technology to ensure the security, it can use as a new green materials. 3, light-resistant, not color, excellent heat resistance, can withstand temperatures above 450 ℃. 4, release high emission reached 20,000 and 30,000 per cubic centimeter of two kinds. Recommended dosage of 2 to 5%
