Silica gel desiccants are largely used in the Consumer products like Food, Leather, and Packaging to protect goods from Moisture Depreciation. Silica gel is one of the most widely used desiccant due to its exclusive property of Moisture adsorption, various sizes, shapes and saturation indicating properties that can cater to any application. They are packed in form of small bags, tiny cylinders or tablets which help the user fit it in any type of packaging making it more users friendly. These desiccants can be regenerated by applying heat for a specific time period which lets it retain its original properties making it re-usable.
Silica Gel Beads are spherical forms of silicon dioxide which are derived artificially from Sodium Silicate. Beads are in colored and transparent forms. They are available in various sizes ranging from 1 mm to 8mm. They adsorb relatively up to 40% moisture of their weight which makes it amongst the most favorable moisture adsorbing inert material that can be in free forms or enclosed in some packaged forms. Silica beads are used in air breathers.
Specifications of Usage
For one liter volume container, half gram of silica gel is required to keep it safe. Change in relative humidity can also affect the absorption capacity. If the relative humidity is 20%, then the gel can absorb 10% of its weight. If the relative humidity is 50% or 90%, then the gel can absorb about 23% or 36% of its weight respectively.
When it comes to using an easy desiccant which is weightless and can be reused, then silica gel is the right choice. It can be used in many industries. It is also available in different packing sizes, enabling it to be used in various packages. Some companies prefer colored gel to indicate the presence of humidity and some prefer silica gel white.
