Problems solved by technology

However, when the particle size of tourmaline is large, this effect is not obvious. Based on the understanding of crystal characteristics, people break large crystals into small crystals and find that their ability to emit electrons to negatively ionize the surrounding air is improved. The concentration of negative ions in the air in the instrument measurement unit has increased
Therefore, people naturally

Embodiment 1

[0021] Embodiment 1 Get 150 grams of tourmaline ≤ 50 μm obtained by finishing, 830 grams of deionized water and 20 grams of dispersant hexametaphosphate aqueous solution are placed in the stirring mill, and the corundum microbeads (particle diameter is about 2mm) At 180 rpm for 10 hours, 99.5% of the tourmaline slurry with a particle size of 1.0-2 μm is obtained. After the end, the slurry is discharged from the bottom of the mixer, and the grinding medium is separated by filtration. The grinding medium is deionized. After washing with water, it is dried and recovered. The filtered slurry is measured by an atmospheric ion concentration measuring and controlling instrument: the concentration of negative ions in the air around the tourmaline slurry is 35,000 / cm 3 (static point), the corresponding firing rate is 120 / sec.

Embodiment 2

[0022] Example 2 Take 200 grams of tourmaline ≤ 50 μm obtained by finishing, 770 grams of deionized water and 30 grams of dispersant hexametaphosphate aqueous solution are placed in the stirring mill, and the grinding medium corundum microbeads (particle diameter is about 1mm) At 180 rpm for 15 hours, 99.7% of the tourmaline slurry with a particle size of 1.0-1.5 μm is obtained. After the end, the slurry is discharged from the bottom of the mixer, and the grinding medium is separated by filtration, and the grinding medium is statically removed. Rinse with deionized water and recover by drying. The filtered slurry is measured by an atmospheric ion concentration measuring and controlling instrument: the concentration of negative ions in the air around the tourmaline slurry is 40,000 / cm 3 (static point), the corresponding firing rate is 160 / sec.

[0023] This shows, adopt the method of the present invention, can obtain stable nanoscale ultrafine tourmaline crystallite, thereby t...

Abstract

This invention discloses a method for preparing a kind of negative-ion material. When the particle diameter of tourmaline is disintegrated below 1 micrometr, its one end is electrically positive and the other end is electrically negative, and this will formide its further disintegrating. This invention solves this special electrical characteristic of tourmaline primarily. According to this method, we can get dimensional stable ultra-fine microcrystal tourmaline, advance its function of releasing negatron by times. This method uses wet agitation to mill super fine powder. The super fine ourmaline powder, whose particle size is fine, distribution is thin, particle shape is regular, is prepared through using disperser reasonably, milling medium, optimizing technological condition, and so on.

Description

technical field [0001] The invention relates to a preparation method of a paint raw material, in particular to a preparation method of a paint raw material with the function of releasing negative ions. Background technique [0002] Tourmaline is a silicate mineral with a complex ring structure characterized by boron and its main chemical composition is SiO 2 、FeO+Fe 2 o 3 , B 2 o 3 、Al 2 o 3 、Na 2 O, MgO, Li 2 O, MnO 2 Wait. Tourmaline minerals are characterized by piezoelectricity and pyroelectricity. Under the condition of temperature and pressure changes, it can cause the potential difference of tourmaline crystals, ionize the surrounding air, and the electrons that are hit will attach to adjacent water molecules and Oxygen molecules, and make it into air negative ions. The resulting negative ions move in the air, transporting negative charges to bacteria, dust, smoke particles, and water droplets, etc., and the charges combine with these particles to achieve t...
