Abstract
(EN)
The present invention discloses a method for producing white synthetic anorthite particles having an average particle size of 0.1-3 µm and a whiteness of at least 90, the method comprising: a step in which a calcium carbonate powder having a whiteness of at least 80, a purity of at least 99%, and an average particle size of 2-4 µm and selected from the group consisting of calcium carbonates, calcium hydroxides, calcium oxalates, calcium oxides, dolomites, and lead limes, an aluminum oxide powder having a whiteness of at least 90, a purity of at least 99%, and an average particle size of 4-6 µm and selected from the group consisting of aluminum hydroxides, aluminum oxides, aluminum nitrates, aluminum chlorides, aluminum sulfates, aluminum acetates, and commercially available aluminum, and a silica having a whiteness of at least 90, a purity of at least 99%, and an average particle size of 1-3 µm and selected from the group consisting of tetramethyl silicates, tetraethyl silicates, tetrapropyl silicates, tetraisopropyl silicates, ethyl silicate polymers, sodium silicates, potassium silicates, fumed silicas, and precipitated silicas are sequentially put into a dry attrition mill containing zirconia beads, in an amount constituting 70% or less of the attrition mill capacity, and are stirred to obtain a mixed raw material having a composition of CaO:Al2O3:SiO2 = 1:1.1:1.1-1:2.1:2.1; a step for removing the mixed raw material and transferring same to a heat treatment sagger, and then charging the sagger into a heat treatment furnace to perform a heat treatment; and a step for cooling the mixed raw material to room temperature in the furnace after the heat treatment and removing a synthetic anorthite from the sagger. Accordingly, the synthetic anorthite (CaAl2Si2O8) particles have infrared reflective properties, and can thus effectively reflect infrared rays among the energy rays emitted from sunlight and solve various problems such as the occurrence of the heat-island phenomena caused by infrared rays and infrared ray-induced ambient temperature increases.

En conséquence, les particules d'anorthite synthétique (CaAl2Si2O8) ont des propriétés de réflexion des infrarouges, et peuvent ainsi réfléchir efficacement les rayons infrarouges parmi les rayons d'énergie émis par la lumière solaire et résoudre divers problèmes tels que l'apparition des phénomènes d'îlot thermique provoqués par les rayons infrarouges et l'augmentation de la température ambiante induite par les rayons infrarouges.
