Tourmaline powder is a kind of inorganic functional mineral powder made from natural tourmaline ore through crushing, grinding, purification and surface modification. As the most widely used functional mineral powder in health materials, building materials, textile and environmental protection fields, it has core advantages such as environmental safety, permanent negative ion release, far-infrared radiation and high cost-performance. Main types include: ordinary tourmaline powder, high-purity modified tourmaline powder, and nano-grade tourmaline powder.

1.Meticulous craftsmanship: Two production paths ensure controllable and traceable quality

（1）Natural mineral processing

Purified and processed from natural black tourmaline and color tourmaline ores via crushing, grinding, drying and impurity removal. It retains natural mineral activity, low cost, suitable for general scenarios with high costperformance requirements (such as ordinary coating filling, ceramic additives, agricultural soil improvement).

（2）Chemical modification and nano-grinding

Adopting precise processes such as high-purity purification, jet milling, surface activation and organic modification. Raw materials can utilize ore tailings for recycling, realizing “wastetotreasure” and complying with green production trends. Modified products feature high purity, uniform particle size, strong negative ion release ability and consistent performance, meeting the stringent requirements of high-end functional coatings, health textiles and foodcontact materials.

2.Core Features: Six Major Advantages Underpin “Abundant Value”

（1）Environmentally friendly and non-toxic, compliant and worry-free

Free of heavy metals and harmful substances, complies with EU REACH, RoHS and Chinese national standards. Non-radioactive, non-polluting, suitable for indoor building materials, health textiles, children’s products and home decoration.

（2）Weather-resistant and lightfast, long-lasting and stable

Excellent UV resistance, heat resistance and aging resistance. No fading, pulverization or failure after longterm outdoor use, stable in high temperature, humidity and acidbase environments, making it a “longlife functional powder” for building exterior and outdoor facilities.

（3）Acid and alkali resistant and corrosion resistant

Outstanding alkali resistance, perfectly compatible with cement, latex and resin systems; stable to weak acids and chemical corrosion, no deterioration, widely used in anticorrosion coatings and functional building materials.

（4）Strong negative ion performance and excellent functionality

Permanent release of negative ions and farinfrared rays, effectively purifying air, removing odor and formaldehyde. High functional efficiency, small dosage can achieve full effect, reducing material cost.

（5）Good dispersibility and convenient construction

Fine powder, good compatibility with waterbased and solventbased systems, no agglomeration. Suitable for coatings, mortar, plastics, rubber and ceramics, simple processing and construction.

（6）Batch stability and controllable quality

Formal manufacturers adopt ISO 9001 quality management system, ensuring consistent fineness, purity and negative ion index in each batch, avoiding production and construction losses.

3.Empowering all industries: From basic building materials to high-end manufacturing, covering all sectors

（1）Building Materials Industry

Functional coatings, interior wall putty, thermal insulation mortar: release negative ions, purify air, moistureregulating and anticracking;Ceramic tiles, sanitary ware: antibacterial, deodorant, healthcare function;Road and infrastructure: improve durability and antiaging performance.

（2）Plastics and Rubber Industry

Functional plastics, health textiles, shoe materials, cables: enhance antibacterial, anion and farinfrared functions, meeting environmental protection and health standards.

（3）Industrial Coatings and Health Applications

Antibacterial coatings, anticorrosion coatings, water treatment materials: purify water quality, inhibit bacteria, extend service life of steel structures and pipelines.
