Multifunctional tourmaline material and manufacturing method thereof

Abstract

The present invention is multifunctional Tourmaline material and its preparation process. Tourmaline material has permanent electric field characteristic, powerful pyroelectic effect to initiate emission of negative ion, hydroxyl ion and far infrared radiation and has trace element capable of bein absorbed by human body. During preparation, Tourmaline is heated at 800 deg.c inside electric furnace through temperature raising, temperature maintaining and temperature reducing for 12 hr each, and through heating in chlorine atmosphere and while adding silica, its silicon content reaches 45 %. The multifunctional Tourmaline material may be used in beautifying, purifying air and water and deodorizing in refrigerator.

Description

technical field [0001] The invention relates to a multifunctional tourmaline material and a manufacturing method thereof. It is a natural active gemstone, which has the functions of health care and beauty, air and water purification after processing, and belongs to the technical field of multifunctional materials. Background technique [0002] Multifunctional materials used today are artificial electret ferroelectrics. This material has the function of generating a magnetic field, but there must be an external force to determine the strength of the function, so the stability of the function is very poor, and its function is easy to attenuate or disappear, so it must be made by artificial electret; another method is to use electronic poles. Chemical, resulting in a single function. Although this method is relatively simple, the ozone produced is harmful to the human body, especially because it is expensive and inconvenient to use. As for the far-infrared ceramic powder materi...

This material has the function of generating a magnetic field, but there must be an external force to determine the strength of the function, so the stability of the function is very poor, and its function is easy to attenuate or disappear, so it must be made by artificial electret; another method is to use electronic poles. Chemical, resulting in a single function. Although this method is relatively simple, the ozone produced is harmful to the human body, especially because it is expensive and inconvenient to use. As for the far-infrared ceramic powder material, it only has the effect of infrared rays. Its cost is relatively high, and ordinary people are unable to use it.
