r/rGongyi Tianhe Water Purification Materials Co., Ltd. produces activated alumina. The company has introduced top German technical equipment and imported raw materials from BASF Chemical Company. The products are globally leading adsorbents, activated alumina, which are directly exported to countries such as the United States, GE Corporation, Japan Itochu Corporation, Germany Siemens, and Henkel International. Gongyi Tianhe's products have won praise from foreign customers.<< r
rrActivated alumina is a porous, highly dispersed solid material with a large surface area. Its microporous surface possesses the characteristics required for catalysis, such as adsorption properties, fluoride removal capabilities, drying properties, surface activity, and excellent thermal stability. Therefore, it is widely used as a household desiccant, as well as a catalyst and catalyst carrier in chemical reactions.<< r
rrPurified active alumina is a white, spherical, porous particle with uniform particle size, smooth surface, high mechanical strength, strong moisture absorption, and does not expand or crack after absorbing water, maintaining its original shape. It is non-toxic, odorless, insoluble in water and ethanol, and has a strong adsorption capacity for fluoride. It is mainly used for removing fluoride from drinking water in areas with high fluoride levels.<< r
rr >>Modern activated alumina for water purification has the ability to selectively adsorb moisture from gases, water vapor, and certain liquids. After saturation, it can be heated at temperatures ranging from about 175-315°C to remove the water and be regenerated. The adsorption and regeneration processes can be repeated multiple times. In addition to being used as a desiccant, it can also adsorb the vapor of lubricating oils from polluted oxygen, hydrogen, carbon dioxide, natural gas, etc. It can also be used as a catalyst and catalyst carrier, as well as a chromatographic analysis carrier.<< r
