Use
Mainly used in the dry, moisture, rust. prevent apparatus, meter,electrical equipment,drugs,food, textile and other various packaging items damp, also can be used as catalyst carrier and organic compound dehydration refined. Because of its high packing density and low humidity, moisture absorption effect obvious characteristics, more can be used for air purifying agent to control air temperature. Marine transportation for the goods during transport due to the water in large and damp metamorphism, with this product can be effective to wet moisture-proof, make the quality of the goods are protected. Also often used in parallel between two layers of the shutter seal dehumidification, can keep the two layers of glass lit degrees.
