Activated alumina desiccant, strong moisture absorption, can effectively prevent the damage caused by condensation in the container due to temperature and humidity changes during the ocean transportation – moisture, mold, rust, oxidation, etc., such as the appearance of water stains in the carton Damage to the outer packaging, and even affect the quality of the product, such as rusting or detaching the metal parts. Principle of Moisture Absorption of Activated Alumina Desiccant: The composition of desiccant for container is calcium chloride. Under the condition of 25 ° C and relative humidity of 90%, the maximum capacity of adsorbed water vapor can reach 250% of its own weight, reaching the foreign similar products. Performance.
The activated alumina desiccant for the adsorption desiccant utilizes the micropores held by the material itself to adsorb the water molecules in the air by capillary action, and at the same time relies on the suction and desorption of the suction dryer and the heat of adsorption to remove the adsorption of the desiccant. Moisture. Material: Activated alumina, molecular sieve, life is different according to the temperature of the intake air, 2-6 years, according to the filter after the dryer to determine whether a desiccant is needed. If the filter is drained, it needs to be replaced immediately. The alumina desiccant can also be judged according to the form of the desiccant and the actual condition of the gas end. Excessive use of desiccant, activated alumina desiccant loses activity, can not drain moisture, compressed air moisture exceeds the standard. Affects the normal operation of gas equipment and product quality, activated alumina desiccant failure live powder shedding, affect Dryer life.
