  • 1. Activated alumina
    The desiccant is spherical, white, odorless, tasteless, nontoxic and insoluble in water and alcohol. It is resistant to thermal shock and abrasion with high mechanical strength and strongly absorbs moisture (draining). The desiccant particle does not expand or crack after absorbing water.
    Activated alumina is used in heatless dryer systems to produce a constant supply of dry air with better humidity than the dew point of -70 ° C.
    Activated alumina removes acid, Â transformer oils, lubricants and refrigerants that form acid degradation when used. Activated aluminum will remove corrosive acids, thereby protecting valuable equipment

    hat hut am

    Molecular is the synthetic crystallinity of zeolites, in which the atoms are arranged in a certain pattern. Inside, the porous structure is linked by smaller-sized cavities that form molecules. The molecule can absorb about 20% of the weight of water before the relative humidity of the surrounding air increases. These characteristics allow the molecule to maintain very low dew points (-50 ° C 10% by weight of absorbed water). This material is also capable of rapidly absorbing water vapor and maintaining a high adsorption efficiency at high temperatures up to 90 ° C.

    3. Some applications of desiccant particles (Activated alumina)
    Activated alumina is widely used as an effective adsorbent in gases such as acetylene, methane, oxygen along with liquids such as Benzene, Freon, hydraulic oil, Kerosene, transformer and vegetable oils.
    3.1 Used as catalyst
    Activated alumina is used for a wide range of adsorbent materials and catalyst applications such as the absorption of the catalyst in the production of polyethylene and hydrogen peroxide. Besides, it is used as a selective adsorbent with many chemicals including arsenic and fluoride.
    3.2 Moisture absorbent
    When used as a desiccant, activated alumina works by a process called adsorption. The water in the air actually sticks to the primary alumina in the middle of the fragments when the air passes through them. Water molecules are trapped to make sure that the air is dried out as it passes through the filter. This process is reversible. If the activated alumina is heated to ~ 200 ° C, it will release the trapped water. This process is called desiccant regeneration.
    3.3 Fluoride adsorbent
    Activated alumina is also widely used to remove fluoride from drinking water, especially in the US. However, in certain areas, such as the Jaipur region of India, fluoride in water is excessive. The new aluminum filter can easily reduce fluoride concentrations from 0.5 ppm to less than 0.1 ppm
    3.4 Vacuum system
    In the vacuum system, activated aluminum is used as a charged material in the fore-line trap to prevent oil generated by the rear-rotating vane pump from spilling into the system.
    3.5 Biomaterials
    Its mechanical properties and non-reactivity in biological media allow it to be used by a suitable material to cover frictional surfaces in the prosthesis (e.g., hip or prosthesis).
