What is tourmaline powder?
Tuomalin powder is a kind of powder obtained by removing impurities from Tuomalin ore and mechanically crushing it. The tourmaline powder after processing and purification has high negative ion generation rate and far infrared emissivity. Tourmaline is also called tourmaline.
Processing technology of tourmaline powder: The original tourmaline ore mined from the mine itself is very impure. The crystal structure needs to be completely selected by manual selection and washed in water. This process can remove many impurities and make tourmaline more pure. Dry the selected ore and treat it with a jet mill. The powder processed by jet mill has several characteristics, such as fine fineness and uniform distribution, which avoids the uneven thickness of powder.
Physical properties of tourmaline powder
The color of tourmaline powder varies with different components: tourmaline powder rich in Fe is black, tourmaline powder rich in Li, Mn and Cs is rose and light blue, tourmaline powder rich in Mg is often brownish yellow, and tourmaline powder rich in Cr is dark green.
In addition, tourmaline powder often has a color band phenomenon, and the vertical C axis forms a horizontal color band from the center outward, or the colors at both ends of the C axis are different. Sometimes there may be vertical L3 cracks. The hardness is 7 ~ 7.5. The relative density is 3.03 ~ 3.25. With the increase of iron and manganese content,
The relative density also increases. It is not only piezoelectric, but also pyroelectric (because its unidirectional axis L3 is the only polar axis). Specification of tourmaline powder
Tourmaline powder is mainly composed of tourmaline powder, ultrafine tourmaline powder and nano tourmaline powder according to different uses. Applicable industries include: hugs, cigarettes, coatings, textiles, cosmetics, water purification, air purification, electromagnetic radiation prevention, health care products, etc.
At present, tourmaline powder produced in China is mostly 100- 1000 mesh. Our factory can process 1000-4000 mesh tourmaline powder after upgrading. Ultra-fine tourmaline powder can be made into ultra-fine fibers, and made into anti-magnetic, fire-proof and warm quilts, cotton pads, shirts, vests and insoles against electromagnetic radiation.
What are the uses of tourmaline powder?
1, electronics industry.
In electronic industry, tourmaline can be used as a wavelength adjuster in radio industry and a polarizer in polarizer. Tourmaline has perfect crystallization, no bending and no cracks, and can be used as a piezoelectric instrument to measure stamping in air and water. 2. Acoustoelectric materials. Tourmaline can be used in sonar elements. Generally, natural tourmaline crystals are used, preferably colorless or pink gem-grade crystals.
3. Test material standards, instruments and components on industrial equipment. Tourmaline is often used as a standard when approving piezoelectric fluid pressure gauges and testing instruments.
4. Electromagnetic wave protector. In a new practical patent (CN2358663Y), a manufacturing method of a harmful electromagnetic protector is introduced. The protector consists of a layered structure, the first layer is a tourmaline particle layer; The second layer is the glue layer; The third layer is a plastic film layer; The fourth layer is also a glue layer; The fifth layer is the paper layer.
