Tourmaline powder is a powdery material made of natural tourmaline by crushing, grinding and other processes. The following is a detailed introduction to it:

1. Basic characteristics

Chemical composition: The chemical formula of tourmaline powder is NaRAlSiOBO(OH,F), where R represents metal cation.

Crystal structure: Tourmaline belongs to a triangular crystal system of a ring structure silicate mineral, the crystal is nearly triangular columnar, with glass luster and rosin luster, translucent to transparent.

Physical properties: Tourmaline powder has a high specific surface area and good thermal conductivity, and can produce negative ions and far infrared radiation.

2. Classification and specification

Classification: According to different uses and particle size, tourmaline powder is mainly divided into tourmaline powder, ultra-fine tourmaline powder, nano tourmaline powder and so on.

Specifications: The specifications of tourmaline powder are usually expressed by the number of mesh, such as 100 mesh, 325 mesh, 800 mesh, 1250 mesh, 3000 mesh, 6000 mesh, etc., and the domestic maximum can reach 20,000 mesh. The larger the mesh number, the finer the grain size.

3. Application fields

Water treatment: Tourmaline powder has the characteristics of spontaneous polarization, can form an electrostatic field, and effectively adsorb metal ions and acid ions in water, so as to purify water.

Health textiles: Tourmaline powder can improve the number of negative oxygen ions in the air, with health and physiotherapy effects, can be used to manufacture clothing and clothing with health functions, such as underwear, bed sheets, etc.

Coating additive: tourmaline powder is added to the coating as an additive, which can not only meet the basic requirements of the coating, but also release negative ions, and has a certain sterilization effect.

Photocatalytic material: tourmaline composite material combined with TiO2 can improve the photocatalytic activity and improve the efficiency of TiO2.

Plastics and rubber products: tourmaline powder can be used in the manufacture of various plastics and rubber products to improve the performance of products.

Agricultural applications: Tourmaline powder can be used in the research and development of soil remediation and plant growth promoters to promote plant growth.

Electromagnetic wave protection: Tourmaline powder can be used to develop electromagnetic wave protection products.

Building materials: Tourmaline powder can be used in the production of ceramic products, such as purple sand, Jun porcelain, ceramic vessels, as well as floor tiles, ceramic particles with ceramic filters, paints and coatings.
