On the other hand, the particle size of the amethyst powder contained in the polyurethane resin adhesive composition according to the present invention is preferably 900 to 1,000 mesh.

Korean-made amethyst according to the present invention is SiO ₂ and a reddish blue colored full-molecular structure 6-crystal system, the hardness is 7 ~ 7.4, is produced in the Martha loess and there is necessarily vein. In addition, it has the effect of mind and body stability at the most stable regular wavelength of 32.786 kHz / second. On the other hand, the far-infrared emissivity is 0.91 (5-20 μm, 37 ° C.), and the radiation energy is 6.20 × 10 ² (W / m ² · μm, 80 ° C.).

Amethyst is generally produced in several parts of the world. Brazil, Uruguay, Zambia, Africa, Korea, etc. are the main producers, and the application of amethyst jewelry is possible in all of the above countries. As a result, it was found that the application of new health materials was unreasonable except in Korea.

The reason is that it cannot oscillate at a certain frequency, and lead, arsenic, and some amethysts contain isotopes (radioactivity), which are fatal to the human body. For that reason, Korean amethyst made of 99.9% high-density SiO ₂ and generating a certain wave is recognized as the best product in the world.

In other words, Korean amethyst is good for clearing the head, and having excellent effects on mind stability, headache, migraine, etc., and Korean amethyst aged 60 million years in ocher mud attracts geomagnetism into the body due to the energy of 2 ~ 3 ℃ more than other materials More than 10,000 crystal particles are effective in promoting cerebral activity, reducing the body's accurate rhythm and health. In addition, the hexagonal molecular structure corrects and disturbs the disturbance of the biocurrent by vibrating millions of times (32.786) per second. Therefore, it cleans and cleanses and has sterilization and growth promoting effects, and is the best for arthritis, muscle pain, nerve stability, skin and fatigue recovery.

On the other hand, the research results of Japan and South Korea's research institutes emit far more than 91% of far infrared rays, which attracts a lot of attention recently, to balance the sugar balance of diabetes and help alcoholism.

For reference, there is a medical use record in consent bogam, non-emergency geumbangbang, distilled herbs and the like. In other words, the herbaceous wood has a pregnancy record of a woman who has been pregnant for more than 10 years because of the cold body, and the functional pollution-free plastic containing amethyst powder is excellent in preventing and treating various diseases. .
